This product uses the electronic dust cleaning. Tobacco and exhaust fan suction piping, the primary device - purification rectifier room, the use of inertial gravity purification technology, the special structure of the room gradually graded physical separation of large particle contaminants and balanced rectifier. Isolated from the large-particle droplets under its own gravity into the discharge tank. The remaining small particle pollutants into the secondary device - high-voltage electrostatic field, electrostatic floor part two, the first stage of ionization, a strong electric field so that the particle charge, the charged particles, these charged particles reach the second level of dust device immediately after collecting electrode adsorption, and some charring. Meanwhile, the high-voltage electrostatic field degradation of harmful ingredients play disinfection, in addition to taste effect. Finally, filter grille, clean air from the outdoors. The company recently developed the production of complex industrial waste gas purification device using a plasma electrostatic field dust to taste technology, efficient and fast to handle all types of industrial waste gas, so that after dealing with emissions to the outdoor air to achieve the required discharge standards GB. The device has the following six characteristics: (a) absorption in addition to fine dust, powder, and degradation of toxic and harmful gases, to remove all kinds of smell. (B) high purification efficiency and fast long-lasting, no secondary pollution. (C) energy-saving and low consumption, low wind resistance, low noise. (D) standard modular design, a series of products to adapt to the requirements of a variety of waste gas treatment. (E) Easy to install, easy maintenance, low running costs. (F) intelligent control, set security, failure to display. The device has been successfully applied to woo established American owned lighting (Shanghai) Co., Ltd. and Philips Electronics (Shanghai) Co., Ltd., the factory floor to the national emission standards, and achieved satisfactory results. The scope of application can be widely used to produce all kinds of smoke and fine dust, industrial sites, such as tobacco, rubber, chemical, welding, paint, casting, heat treatment, plastic, textile, machinery and cutting industry and enterprise.
