Dryer dust collector is designed for φ 1.5×12m, φ 1.5×15m, φ 2.2×12m, φ 2.4×16m and other specifications of the dryer flue gas dust removal development and development of new products, the product adopts the new technology of vertical kiln fiber bag dust removal which won the scientific and technological progress award of the ministry of the year, microcomputer control sub-chamber back blowing, timing, resistance, temperature detection and display, etc. So that the glass fiber bag dust collector in drying flue gas dust removal, stable operation, the chimney outlet emission concentration is lower than the prescribed 150mg/ m3N emission standard (the actual guarantee is no more than 100mg/ m3N), the equipment can not stop the room for bag change, simple operation, reliable, used for vertical kiln iron silicon furnace, industrial electric furnace, low operation cost, It is an ideal equipment for dust removal of domestic dryers.
Operating characteristics of dryer dust collector
Bag dust collector is stable, simple maintenance, reliable operation is widely recognized, it is 0.1 micron particles of dust gas, dust removal efficiency can be as high as 99%, dryer waste gas dust selection bag dust collector without considering the emission concentration exceeds the standard problem. Dryer anti-condensation glass fiber bag filter is an ideal dedusting and purification equipment at present.
The dedusting equipment of dryer adopts microcomputer control, chamber back blowing, timing dedusting, and equipped with temperature detection display, over temperature alarm device, cw300-FCA anti-condensation glass fiber filter bag, can effectively prevent the filter bag condensation, also won't burn the filter bag. The diameter of the slag dryer is 3×24 meters. The two-stage dust removal process is changed to the first stage LFEF7×358 -- HSY/H anti-condensation bag dust collector. According to the determination of the environmental protection department, the exhaust gas is 42621 standard cubic meters per hour, the dust concentration of the import is 69620 mg per standard cubic meter, and the dust concentration of the export is 147 mg per standard cubic meter. Meet emission standards.
Dryer dust catcher is specially used to deal with the tail gas of dust catcher and dryer. The dryer is by the front of the hot blast stove into the hot air to roll drying materials. Due to the burning of coal in the hot blast stove in front of the dryer, the exhaust gas produced contains a large amount of SO2 and water vapor, which is easy to condense and produce strong corrosion. Under the condition of high temperature and oxygen enrichment, it is also easy to generate highly corrosive H2SO3. Therefore, the exhaust gas treatment of the dryer has been a serious problem that troubles the production. In the treatment of this kind of gas, we must pay attention to the above exhaust gas characteristics. In view of this working condition, our company has carried out special treatment on the dust collector, the flowerplate made of ordinary 325 steel plate is changed to stainless steel, the filter bag is made of high temperature resistant and corrosion resistant filter bag -- Flumeis, and the framework is made of silicone (or stainless steel). Dust collector interior with epoxy polyester anticorrosive coating after three layers of treatment. The outer layer is insulated with 10 cm thick light rock wool and color steel plate. After the above improvement, the dust collector can meet the working conditions of the dryer.
Dryer dust removal equipment is suitable for food, pharmaceutical, feed, metallurgy, building materials, cement, machinery, chemical industry, electric power, light industry of dust gas purification and dust material recovery.
The use of dryer dust remover
Under normal cleaning conditions, the residual ash layer remains stable, that is, the resistance before and after cleaning is basically the same, which overcomes the phenomenon that the residual ash layer and the resistance accumulate with the extension of the running time. This kind of wind stop and impact vibration is the combination of the optimization of the ash removal method, thus producing high strength ash removal effect. The weight of the remaining ash layer is 10~20 times more than the average amount of ash settled in a filter cycle. In the glass fiber flat bag with vibrating dust removal, the weight of the remaining ash layer is less than one third of the average amount of deposition in a filtration cycle, or more than one time.
