Design principles of waste gas purification equipment

Design principles of waste gas purification equipment
1. Safety elements are the first principle. Organic waste gas is usually flammable, explosive, toxic and harmful gas. Therefore, the safety index of the large concentration of volatile organic compounds must be operated below the lower explosive limit 1/4 value. Experienced designers take into account sudden concentration volatilization. If the manufacturer's process formula feeding error, production line temperature or pressure parameters abnormal, there should be emergency control and measures. This is particularly important in the chemical industry.
2. Environmental protection standard emission is the second principle of organic waste gas purification device selection must be optimized and reliable, which lays a foundation for standard emission. Because of the various components of organic waste gas, the quality of the purification device directly affects the safe operation and purification effect.
3. The function of all organic waste gas purification devices is not omnipotent, and the purification object is highly targeted. Therefore, organic waste gas contains particulate matter, halogen waste gas, heavy metals and other compounds, which will interfere with the organic waste gas purification device and even destroy the purification effect. Therefore, such compounds must be thoroughly purified before entering the organic waste gas purification device.
4. Electric control and automatic control is the command center of organic waste gas treatment engineering system, so the design of electric control principle should be simple and reliable. Electrical components should be safe and reliable. There should be a good working environment.
5, the safety of organic waste gas purification and treatment project: the vast majority of organic waste gas is flammable and explosive, toxic and harmful compounds, because this dangerous chemical in the purification and treatment project, especially important for safety. Our design and manufacturing principle: safety first, followed by standard. Without security, nothing is meaningful. The safety of organic waste gas purification project consists of two parts. First, the safety and reliability of the organic waste gas purification device itself; Second, the safety and reliability of the design of organic waste gas purification system. As long as there is a safety problem, there must be a safety hazard.
6, organic waste gas pretreatment system in organic waste gas is usually particulate matter, paint fog, heavy metals, halogen compounds and other mixtures. Therefore, these mixtures should be strictly purified before the purification of organic waste gas, so as not to affect the purification effect of the post-stage. Pre-treatment usually uses pre-processor, water curtain type purifier, spray purifier, dust collector, high efficiency dust collector and other supporting purification equipment and accessories.
