Classification and characteristics of dust collector baghouse
There are many kinds of dust collector equipment, namely: filter cylinder dust collector, pulse dust collector, cloth bag dust collector, welding dust collector, industrial dust collector, cyclone dust collector, etc. The upper, middle and lower box structure of the dust removal equipment is the partition structure, so the dust collector is composed of the ash bucket, upper box, middle box, lower box structure and other components. In operation, the dust gas by the air duct into the dust bucket, coarse dust grain straight to the bottom of the dust bucket, fine dust particles with the flow turn up into the middle, the box structure, dust, product attached on the outer surface of the filter bag, after the filtered gas into the box structure to the net gas collector-exhaust duct, through the exhaust fan to the atmosphere. The process of ash removal is to first cut off the net air outlet air duct of the chamber, so that the cloth bag is in a state of no air flow through. Secondly, after opening the pulse valve, ash removal is with air compression and equipment pulse blowing, shut off valve shutdown time is enough to ensure that the dust removed from the filter bag, sinking into the ash bucket, also avoid the dust from the surface of the surface of the filter bag, and with the airflow adhesion to the adjacent filter bag surface phenomenon, make the filter bag ash removal thoroughly, and by the programmable controller of exhaust valve, pulse valve and impeller feeder equipment automatic control. Features of dust collector The use of chamber air stop pulse blowing ash removal technology has overcome the disadvantages of conventional pulse and dust collector and chamber reverse blowing dust collector, not only strong dust removal capacity, high dust removal efficiency, low emission concentration, less air leakage rate, less energy consumption, less steel consumption, less area, stable and reliable operation, and good economic benefits. Suitable for metallurgy, building materials, cement, machinery, chemical industry, electric power, light industry and other industries of the dust-containing gas purification and material recovery. Due to the use of separate chamber air stop pulse spraying to clear the ash, spraying once can achieve the purpose of thorough ash cleaning, so the ash cleaning cycle is extended, reducing the ash cleaning energy consumption, and the pressure gas consumption can be greatly reduced. At the same time, the fatigue degree of filter bag and pulse valve is correspondingly reduced, so as to multiply the life of filter bag and valve sheet. Maintenance, bag change or filter cartridge can be carried out in non-stop system fan and normal operation conditions of the system. Change the bag or filter tube mouth with elastic rising ring, good sealing performance, firm and reliable. The filter bag keel is polyangular, reducing the friction between the bag and the keel, extending the life of the bag, but also easy to unload the bag. The dust collector also adopts the upper bag pumping method. After the skeleton is drawn out when changing the bag, the dirty bag falls to the lower part of the box and is removed by the human hole, which improves the operating conditions of changing the bag or the filter tube. The box adopts gas tightness design, good sealing, the inspection door with excellent sealing material, in the production process with kerosene leak detection, the air leakage rate is very low. The inlet and outlet air duct are compact and the airflow resistance is small. The applicable scope of application of dust collector is applicable to the flue gas treatment and dust removal system of ironworks, steel plant, ferroalloy plant, refractory plant, foundry plant, power plant, etc. Waste incinerator, coal-fired boilers, fluidized bed boilers and other flue gas filtration. Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production places. Alumolysis, lead, tin, zinc, copper and other rare metals smelting flue gas filtration, fine material recovery, liquid and solid separation. Chemical industry, coke, carbon black, dye, pharmaceutical, plastic and other fields of liquid and solid separation and fine material recovery. Dust treatment and purification collection for mining, grain processing, flour, electronics industry, wood processing, etc.
