Here are Two Types of Dust Removal Equipment
Vortex Wet Dust Collector
A vortex wet dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a vortex wet dust collector consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air purifiers, which use disposable filters to remove dust.
Bag Filter
A bag filter is a type of air pollution control device that uses a series of bags to remove particulate matter from gas streams. The bags are made of a filter media, such as polyester, nylon, or glass fiber, that has small pores that trap the particles. The gas stream flows through the bags, and the particles are captured on the surface of the bags. The bags are then cleaned periodically to remove the captured particles. In industries, we use something called a bag filter to keep the air clean. This is especially important when we're dealing with boilers. The bag filter has special bags made of materials like polyester or nylon. These bags have small holes that trap the particles when the dirty air passes through them. This is particularly useful in processes involving boilers, where keeping the air clean is crucial.
Improve Health and Safety
When the air is filled with dirt, dust, debris, chemicals or gasses, it can affect the lungs of anyone who breathes this air in. Not only that, but this particulate can collect on or near equipment, posing a significant fire hazard. With a vortex wet dust collector, these contaminants are removed from the air, cleaning the air and improving the safety of everyone inside.
Increase Productivity
When dirt, dust and debris collect on equipment, it can make its way inside, interfering with the mechanics of the equipment. This can lead to slower machines and broken equipment. Compromised machinery constantly needs attention and repairs. Vortex wet dust collectors remove this risk, allowing your machinery to work at optimal performance.
Lead to Better Product Quality
With dust in the air, it can collect on products throughout the manufacturing process. This can negatively impact the quality of the finished product. Vortex wet dust collectors, however, significantly reduce the dust, smoke and fumes in the air, keeping them away from finished products and thus improving their quality and increasing customer satisfaction.
Help You Meet Compliance Regulations
There are numerous laws and regulations in place for workplace safety. Some of these regulations are related to the environment and the quality of the air. Poor air quality can cost you heavily, not just in fines, but by creating potential hazards that can damage your factory or affect your employees. Vortex wet dust collectors help you to comply with governmental regulations, as well as keeping everyone (and everything) inside the building safe.
Installation Guidelines of Vortex Wet Dust Collector
Pipe and Fittings
All piping connections should be made using good general practices for the materials involved. For pipe that is made from PVC or other thermoplastic materials, follow guidelines established by the Plastic Pipe Institute. Before continuous operation is attempted, all connections should be checked for leaks using water. Use care in attaching all pipe connections to avoid excessive piping stresses, especially if the dust collector is of plastic construction. A flexible type of connection, such as hose connection, is generally preferred. To prevent air becoming entrapped, the pipe should rise in the direction of flow and be fitted with a vent valve at each high point. Pipe the vent to a drain. Install a dirt trap and drain valve at every low point and the bottom of every riser to permit flushing. Pipe to a drain. Drain fittings must be isolated from each other. Use a plumber's P-trap or submerge the end of each drain line. Either method will prevent air from flowing in the drain line. Such flows can cause by-passing, or they can interfere with proper drainage of the vessel. Support and anchor all pipe and fittings in order to prevent damage to the equipment or to the pipe itself. Piping should never be supported by the flanges on equipment. It should be supported independently. This will prevent deformation or twisting of the equipment. Heat trace pipe and fittings, if necessary, to prevent freezing.
Duct and Fittings
Support and anchor all duct and components in order to prevent damage to the equipment or to the duct itself. Duct should never be supported by the flanges on vessels or air moving equipment. It should be supported independently to prevent deformation or twisting of the equipment. Use a flexible connection whenever vibration isolators are used, and to minimize noise. Avoid sudden changes in duct size. The included angle of an inlet transition should be 14 degrees or fewer. The outlet transition should be not more than 30 degrees. Elbows should be kept to a centerline radius of at least one and one-half duct diameters. Branches entering a trunk line should be spaced so that they do not enter directly opposite each other. They should enter at an angle of no greater than 45 degrees. Place access doors in the ductwork just ahead of the vessel inlet and outlet connections. Slope duct toward the equipment to prevent splash, spray or condensate from getting into the duct system. Stack height should be sufficient to avoid introducing exhaust air into windows or air intakes. Use guy wires to brace against wind loads. Guy wires and hardware should be stainless steel or other corrosion-resistant material.
Electrical Equipment
Electrical connections should be made only by a qualified electrician. Make sure that all electrical work is done in accordance with applicable codes. Lock out the power source prior to any work being done. Be sure to follow the wiring diagram on the nameplate or terminal box of the electrical equipment. Make sure that motors are wired for the correct supply voltage. Provide ample overload protection and other safety devices. After electrical connections have been made, check the rotation of the fan. Arrows show proper direction of rotation.
How to Maintain Vortex Wet Dust Collector
Use the Right Parts
Make sure your vortex wet dust collector is using the right parts, from the blower, dust filter, a filter-cleaning system, dust receptacle or dust removal system, to cartridges and bag house solenoids, fans and valves. Each part plays a role to ensure the collector is operating at the design point. We recommend using factory recommended replacement parts and be leery of less expensive alternatives.
Free Dust of Hopper
A vortex wet dust collector's hopper should never be used to store dust. The hopper is intended to funnel process dust to a storage bin. Dust accumulating in a hopper creates a potential fire or deflagrating risk. Dust in your hopper will also clog the system and diminish the collector's performance and prevent the pulse-cleaning from doing its job.
Check Diaphragm Valves
It's smart to make checking your diaphragm valves a priority each year. Particularly when new bag houses or cartridges are installed, it is recommended to check the valves and ensure that all filters are cleaned properly from the beginning. Remember that it's always cheaper to replace diaphragm valves than it is to buy new filters because of inadequate pulsing.
Regularly Check Your Ductwork
It's smart to equip your ducting with a flow-activated isolation valve, protecting downstream work areas from the propagation of flame and pressure through the inlet duct when deflagrating occurs in a vortex wet dust collector. If there is deflagrating in a vortex wet dust collector, the pressure will close the valve, preventing the passage of flame and smoke to areas upstream from the valve. The valve latches shut and must be reopened manually. Some parts of the valve may be damaged, and a thorough inspection is required before the valve is back in service.
Make Sure You're Using the Correct Air Pressure in Your Vortex Wet Dust Collector
Compressed air pressure is crucial for the performance and longevity of a dust When compressed air is too low, filter cartridges are not properly cleaned which results in rapid downgrade and saturation. When air pressure is too high, filter cartridges are used up faster and need to be replaced more frequently, driving up cost and maintenance. It's very important to always have your compressed air pressure within the limits of manufacturers recommendations. Your compressed air should be oiled and water free, and the amount should be sufficient for all users performing simultaneous tasks.
Keep an Eye on Pressure Drop
Increasing pressure drop (typically measured in inches of water column)across the vortex wet dust collector affects the ability of the collection system to capture dust. As a safety measure, change filters when airflow reaches a differential pressure. New filters have the lowest pressure drop because of the inherent permeability of the media. As the bags develop dust, some particulate embeds itself into the filter media, which increases the pressure drop.
Create an Inspection or Maintenance Program
To ensure a vortex wet dust collector is working properly, periodic inspections and a maintenance program will go a long way toward keeping your vortex wet dust collector functioning at a high level. Scheduled inspections on a daily, weekly, monthly, semi-annual and annual basis will keep your vortex wet dust collector working efficiently and keep your maintenance costs down. Failing to routinely inspect and maintain your dust collector can hurt its performance, and continued neglect will lead to your vortex wet dust collector not meeting outlet emissions standards.
Inspect the Filter Media
The filter is the most important part of a vortex wet dust collector because it accumulates and supports dust cake. Dust cake is what provides high filtering efficiencies during operation. Regularly inspect the clean-air side of the vortex wet dust collector for leaks and the bags for tears. If pressure drop within a vortex wet dust collector becomes extremely high compared to normal, it may be caused by excessive dust cake or "blinding" of the filter bags.
Types of Bag Filter
Pulse Jet Type:
Pulse jets are the most preferred bag filters in process industries, designed to ensure low-pressure drop and ease of installation and maintenance with components like cages, tube sheets, and venturis. It assures complete gas tightness across the tube sheet that prevents polluted gases' ingression into clean air. It is designed with an optimal air-to-cloth ratio as per its process requirements. Pulse jet type bag filters are primarily used in process industries such as cement, power, steel, etc.
Reverse Airbag:
The Reverse Airbag is ideal for handling high-temperature gases in large volumes. It can facilitate the emission level of 20 to 50 mg/ nm3. The PLC control panel ensures its cleaning operations, optimum pressure drop, and longer lifespan of the bag house. The hook assembly and springs at the top help in the suspension of filter bags and appropriate tensioning. The complete gas tightness is ensured by casing, hopper, and tube sheet that prevents ingression of polluted gases to clean air side. The design of the reverse airbag includes balanced gas distribution of the inlet and outlet plenums that ensures uniform distribution of gases.
Mechanical Shakers:
The mechanical shaker bag filters are designed by attaching tubular filter bags on a cell plate at the bottom and suspending it from the horizontal beams at the top. The polluted gases enter from the bottom and pass through the filter. On the other hand, the pollutants get collected on the internal surface of the bags. Mechanical shaker filter bags have high space requirements due to relatively low air-to-cloth ratio.
Here's How The Bag Filter Works
Inlet of Gas Stream
The gas stream containing particles and contaminants enters the bag filter system.
Filter Housing
The filter housing is a chamber that contains a series of fabric bags. These bags are made from materials such as woven or felted fabric with varying degrees of porosity, allowing them to capture particles of different sizes.
Filtration Process
As the gas stream flows into the filter housing, its velocity decreases due to the larger space available. This reduction in velocity causes the particles carried by the gas to lose their kinetic energy. As a result, the particles start to settle and are unable to maintain their suspension in the gas.
Particle Capture
The fabric bags within the housing act as the primary filtration medium. The bags are strategically placed in such a way that the gas must pass through them. As the gas flows through the bags, the particles are intercepted by the fabric's surface due to various mechanisms such as direct impaction, interception, and diffusion.
Accumulation on Bag Surface
Over time, the captured particles accumulate on the outer surface of the fabric bags. This accumulation forms a layer of dust and contaminants.
Pressure Differential
As the layer of captured particles builds up, it creates a pressure differential between the gas inside the bags and the gas outside the bags. This pressure differential, also known as the pressure drop, is a crucial parameter indicating the performance and efficiency of the bag filter.
Cleaning Mechanism (Pulse Jet Cleaning)
To maintain the efficiency of the filtration process and to prevent excessive pressure drop, the accumulated particles must be periodically removed from the bags. One common cleaning method is the pulse jet cleaning system. This system involves the use of compressed air directed into the bags in a controlled manner. The sudden release of compressed air creates a shockwave that causes the fabric to flex and vibrate. This action dislodges and releases the accumulated particles from the fabric's surface, allowing them to fall into a collection hopper at the bottom of the housing.
Particle Disposal
The collected particles are then disposed of properly, often as waste material.
Continuous Operation
The bag filter system operates continuously, with the filtration, accumulation, and cleaning cycles repeating as needed based on factors such as the type of particles being filtered, the gas flow rate, and the desired filtration efficiency.
How to Maintain Bag Filter
Regular Inspections
Perform routine inspections of your bag filter housing to identify any signs of wear, damage, or leaks. Check for loose bolts, damaged gaskets, or any signs of corrosion. Inspect the housing body, lid, seals, and gaskets for any visible issues. Regular visual inspections enable timely detection of issues and allow for prompt repairs or replacements. Promptly addressing minor problems can prevent major failures and extend the overall lifespan of the housing.
Proper Filter Bag Installation
Ensure proper installation of filter bags within the housing. Follow manufacturer guidelines to guarantee a proper fit, alignment, and sealing of the bags. Avoid over-tightening or under-tightening of closure mechanisms to minimize the risk of leaks or inconsistent filtration.
Ensure Proper Sealing
Check the seals and gaskets of the bag filter housing regularly to ensure they provide a proper and reliable seal. Damaged seals or gaskets may result in bypassing of unfiltered fluid, reducing the efficiency of the filtration system. Replace worn-out or damaged seals promptly to maintain optimal filtration performance.
Scheduled Filter Bag Replacement
Establish a regular schedule for filter bag replacement based on the anticipated filter life and the specific requirements of your application. Proactive bag replacement ensures consistent filtration performance and avoids excessive pressure drop, which can lead to reduced flow rates and system inefficiency. Regularly change the filter bags according to the scheduled maintenance intervals or when they reach their maximum dirt-holding capacity. Neglecting to change the bags in a timely manner can lead to insufficient filtration and potential damage to the housing. Follow proper procedures for bag installation, ensuring a secure and proper fit.
Cleaning and Maintenance of Housing Interior
Establish a regular cleaning routine for your bag filter housing. This involves removing the filter bags, thoroughly cleaning the housing interior, and inspecting the internals for any debris or buildup. Use appropriate cleaning solutions or solvents as recommended by the manufacturer to avoid damage to the housing material. Thoroughly rinse and dry the housing before installing new filter bags to prevent contamination and maintain optimal filtration efficiency.
System Flushing
Perform system flushing or backwashing to remove any particles or contaminants that may have accumulated within the housing. This flushing process helps prolong the life of both the filter bags and the housing, preventing clogging and ensuring uninterrupted filtration performance.
Pressure Testing
Perform periodic pressure tests on the bag filter housing to verify its integrity and ensure there are no leaks. This helps identify any potential issues before they lead to more significant problems or breakdowns. Follow proper protocols and use pressure testing methods recommended by the manufacturer.
Proper Disposal of Used Filter Bags
Follow proper disposal procedures for used filter bags, especially if they contain hazardous or specialized material. Adhering to proper disposal regulations safeguards the environment and prevents any potential contamination. Consult local regulations and guidelines for the correct disposal practices in your region.
Document Maintenance Records
Maintain a comprehensive record of maintenance activities, including inspection dates, cleaning routines, filter change outs, pressure test results, and any repairs or modifications performed. This documentation will help you track maintenance history, anticipate future needs, and identify any recurring issues that require attention.
