        Cloth bag filter

          Working principle of a dust remover

          Dust - containing gas enters the air inlet, the lower chamber and the upper chamber through the filter bag due to various effects of the filter bag. Dust gas is separated, dust is absorbed on the filter bag, and the gas enters the upper chamber through the filter bag through venturis tube and is discharged from the air outlet. During the process of dust gas purification through the filter bag, with the increase of time, more and more dust will accumulate on the filter bag, so the resistance of the filter bag will gradually increase and the amount of gas passing through the filter bag will gradually decrease. In order to make the dust collector work normally, the resistance should be controlled within a limited range (generally 120-150 mm water column). In this way, when the resistance rises to a limited range, the control instrument will issue instructions to trigger each control valve in order to open the pulse valve. The compressed air in the air bag is sprayed into the corresponding filter bag by the passage tube through each hole of the blowpipe. The filter bag expands rapidly under the action of the reverse airflow instantly, which makes the dust accumulated on the surface of the filter bag fall off and the filter bag is regenerated. The dust that has been cleared will fall into the dust hopper and be discharged from the body through the ash discharging system. The dust accumulated on the filter bag will be cleaned regularly and the purified gas will pass through normally to ensure the normal work of the dust collector.

          The bag features of two pulse back - blow filter

          1. Large air volume per unit volume, high dust removal efficiency.

          2. It can directly treat the dust gas with a concentration of up to 1000g/Nm3, and the emission concentration of the treated gas is lower than 50mg/Nm3. It can also meet more stringent emission standards according to the special requirements of users.

          3. For different types of flue gas, different filter materials can be used to treat it so that it can meet the emission requirements and has strong adaptability.

          4, the use of advanced pulse valve, reliable performance. The service life of pulse valve is 1 million times.

          5, the use of advanced PLC programmable controller, timing or constant resistance automatic spray cleaning, automatic operation, small gas consumption, clean thoroughly, stable performance.

          6, online maintenance. Room bag changing maintenance will not affect the operation of the main engine. The structure and working principle of the bag filter is composed of the upper box, bag chamber, ash discharging device and the control system of pulse ash cleaning

          Bag filter application:

          With its excellent performance in casting, metallurgy, machinery, electric power, building materials, ores, cement, chemical industry and other industries, has become the best choice of enterprise dust control.

          Furniture carpentry industry: wood industry, furniture industry cutting, saw, planer, cutting, gong edge, grinding, polishing.

          Chemical industry: Polymer: polypropylene, polyethylene, polyester compound, polyacrylamide, melamine, ion exchange resin, activated carbon fiber, starch, cellulose derivatives, etc.

          Fine chemicals: medicine, pesticide, dyeing cloth material, pigment, chemical fertilizer, explosive, detergent, catalyst, rubber plastic additive, concrete additive, water treatment agent, oil field chemical.

          Inorganic chemicals: acid, alkali, salt, oxide, hydroxide, silica, whitening agent, fine ceramics.

          Industrial kiln: cement kiln, coal-burning glass furnace, coking furnace, compound fertilizer drying rotary kiln, urban garbage drying rotary kiln, ceramic and various building materials combustion phenomenon furnace exhaust dust.

          The dust containing less than 1 m in the gas from the cement shaft kiln accounts for 7.92%, the dust containing less than 2 m accounts for 19.05%, and the dust containing less than 3 m accounts for 24.83%.

          Industrial boiler:

          All kinds of coal, oil, gas industrial boiler and blast furnace gas, pulverized coal furnace, fluidized bed boiler exhaust dust.

          Building materials and mining industry:

          Ultrafine calcium carbonate, kaolin, bentonite, bauxite, magnesium hydroxide, ultrafine quartz, silica gel particles, graphite dust, metal dust, ore dust, coal fly ash dust.

          Metallurgical industry:

          High temperature flue gas dedusting of blast furnace, electric furnace, converter and heating binder in iron and steel industry and dedusting of ore and coke.
