Advantages Of Treating Industrial Waste Gas

Advantages of treating industrial waste gas
Dust removal equipment is mainly applied to cement, steel, non-ferrous metals, electric power, machinery, chemical industry, garbage incineration and other dust pollution industry. The change of total output value of dust removal equipment industry is closely related to internal and external economic development environment and development status of downstream industry. In recent years, the total output value (sales revenue) of our dust removal equipment fluctuated from 13.998 billion yuan in 2005 to 29.07 billion yuan in 2008, with an annual compound growth rate of 27.49%. In 2009, due to the impact of the international financial crisis, the growth rate of the cement, steel, non-ferrous metals, machinery and other industries slowed down significantly, and the output value of some industries even experienced negative growth, which made the total output value of the dust removal equipment industry temporarily drop slightly.
Treatment of dust particles in industrial waste gas by mechanical forces (commonly referred to as gravity, centrifugal force, gravity, etc.). Mechanical dust removal equipment because it only relies on a single mechanical force to carry out dust removal work, so it is relatively simple in structure, operation and maintenance management is also very convenient. But it is more difficult to deal with small particle size dust particles. At present, the dust containing waste gas generated in the activities of iron and steel smelting, cement factory production and other industrial enterprises, contains relatively fine dust proportion is quite large, so it can be used as a first-stage dust removal equipment, filter part of the dust in the waste gas, so as to do the basic work for the filtration of dust containing waste gas in the next stage.
At present, the representatives of mechanical dust removal equipment are gravity dust collector, inertia dust collector and cyclone dust collector. Using the principle of electrostatic dust removal invented by Cottrey more than 100 years ago, when the dust-containing waste gas passes through the dust collector, uneven electric field is generated between the electrodes, the airflow is ionized, and the dust falls into the ash hopper after charging. In the practical application of dust removal cases, the structure of the selection of electrostatic dust removal technology is relatively complex, for the filter of 0.01μm dust particles is not difficult, so the effect of dust removal is very high, but also by increasing the electric field, but also to further improve the efficiency of dust removal, and dust containing waste gas flow, electrostatic dust removal unit can also be processed, but also more economic. Only in use need to pay attention to, electrostatic precipitator in the corona discharge moment, will produce cremation, here need to pay attention to the explosion of dust and other problems.
