Pollution such as sulfur dioxide, nitrogen oxides, and fine particulate matter (PM2.5) has become a prominent environmental pollution problem in my country. Since 2013, the state and departments at all levels have successively promulgated strict laws on the prevention and treatment of air pollution. Our company responded quickly and took the lead in the development of the wet electric demister (WESP), which can be widely used in the treatment of waste gas from coal-fired power plants, chemical, petrochemical, non-ferrous metal smelting, iron and steel, coking, biological, pharmaceutical and other industries. It can effectively remove the acid mist, aerosol particles, dust and other harmful impurities in the exhaust gas, especially the removal of fine particles such as PM2.5.
