Application development and China's industrialization process technology is closely related dedusting equipment, dust removal equipment generally include a mechanical filter, wet scrubber, electrostatic precipitators and fabric filters. Technical performance comparison of four kinds of dust removal equipment as follows: 1, mechanical dust collector is to use gravity settling dust, inertia or centrifugal separation of dust, its collection efficiency is generally 90% or less, low collection efficiency, low resistance, advantages that save energy. 2, the wet scrubber principle is the use of gas-liquid contact wash the dusty gas dust separation into the liquid to remove the dust in the gas. Its slightly higher mechanical dust collection efficiency, but easy to cause secondary pollution washing liquid. 3, the electrostatic precipitator is dusty gas through a strong electric field, so that dust particles charged by the dust at the time the electrode, positively / negatively charged particles were negative / positive electrode plate adsorption of the gas to remove dust. High efficiency electrostatic precipitator dust, but the dust collection efficiency than the impact resistance by large, easily lead to instability in collection efficiency. After the 1990s, electrostatic precipitators are widely used in thermal power generation, cement kilns and other high-temperature, gas opium, conditions more complex in dust pollution. 4, bag filter using fiber filter traps dust and gas in the solid particles form a dust filter cake, and further filtered through a fine dust filter dust cake to achieve efficient dust removal purposes. Bag filter can stably achieve high collection efficiency, dust emissions can be achieved within 5mg / m3, and the collection efficiency than the dust from dust impact resistance, and other characteristics. In general, a particle size less than 10 microns dust (particulate matter can be inhaled) a greater impact on human health, baghouse for particulate matter with a high separation efficiency. Baghouse in dealing with normal temperature flue gas (<120 ℃) ??in the range of application of pollution gradually expanded, with the further development of high temperature and pulse filter cleaning and other technologies, baghouse dust with excellent performance in handling high temperature, get more and more widely used high concentrations of smoke control areas. Zhengzhou Pu Technology Co., Ltd. is specialized in environmental protection equipment research and development of technology-based manufacturing enterprises. Company R & D, design, production and sales, specializes in designing complete a variety of automatic batching, automatic sorting conveyor, industrial dust, air purification, water treatment and other large projects, be modified to optimize the entire system and provide related equipment manufacturing, installation and commissioning and other improved services.
