According to the difference between the metal smelting method and the amount of gas production, the technical characteristics of the exhaust control (operation) line of the metal smelting can be divided into two forms: 1. Large dispersion smelting equipment, adopting the gathering hood to gather smoke and dust collecting chamber -- reducing (dust) speed, dust reduction, cyclone dust removal and spray dust removal - down (smoke and dust) temperature, deacid, flue gas Deodorization, dust water separation, water (concentration) treatment and collection (recycling); 2. Small centralized crucible stove, including gathering hood smoke gathering, cyclone dust removal, spray dust removal, deacid, deodorization, dust water separation, water (concentration) treatment and collection (recovery).
According to the principle of action, duster can be divided into the following:
1. Dry type mechanical dust remover mainly refers to the dust removal equipment, such as settling chamber, inert Dust Collector, Cyclone Dust Collector and so on, which are designed with dust inertia action and gravity action. It is mainly used for the separation or concentration of high concentration coarse particle size dust.
2. Wet dust remover relies on water power to separate and capture dust particles, such as spray tower, scrubber, impact dust collector and Venturi Tube, etc., in the process of processing production, high concentration and large air volume of dust gases are used more. The separation efficiency of the thicker hydrophilic dust is higher than that of the dry type mechanical dust collector.
3, granular bed dust remover uses different particle size material accumulation layer as filter material to block the equipment for filtering the dust contained in the gas solution. It is mainly used for dust discharge points in the production process of building materials, metallurgy and so on. It often filters dust containing high concentration, coarse particles and high temperature.
4. The Bag Filter is a dedusting device that uses fiber fabric or filling layer as the filter medium. It has wide range of use, form, dust size and efficiency. It is mainly used in the place of collecting fine dust, that is, in the exhaust dust collection system and in the air inlet system. In recent years, because of the continuous development of new type of filter materials, the development of fiber filtering technology has also accelerated, new products continue to appear, and the application field is widening.
5. The Electrostatic Precipitator is a dust collector that introduces the dust air into the electrostatic field. Under the action of the high voltage electric field, the gas is ionized and produces electrons and positive ions. They move to the positive and negative poles respectively. When the dust particles flow through the working electric field, they are charged at a certain velocity to the opposite of their negative charge. The plates are removed and settled there, thus being removed from the airstream and collected in the electrostatic precipitator. The dust collector has the advantages of high dust removal efficiency, low resistance, and convenient maintenance and management. It has the same effect as bag filter in collecting fine dust particles.
