The working principle of the dust collector is as follows: Dust gas from the lower open flange into the filter room, coarse particles directly into the ash warehouse, dust-laden gas filter bag filter, dust retention in the bag table, net gas through the pocket to Clean room, by the fan into the atmosphere. When the filter bag surface dust continues to increase, the programmer began to work, one by one to open the pulse valve, so that compressed air through the nozzle on the filter bag for cleaning, so that the bag suddenly inflated, in the reverse airflow, Of the dust quickly from the filter bag into the ash bin, dust discharged from the discharge valve.
Dust catcher mainly by the upper box, the box, ash bucket, into the wind flow tube, bracket filter bag and injection device, ash removal device and other components. Dust-laden gas from the dust into the inlet manifold into the sub-room ash bucket, and in the ash bucket diversion device under the diversion of large particles of dust is separated directly into the hopper, and more fine dust into the The middle of the box and adsorbed on the outer surface of the filter bag, clean gas through the filter bag into the upper box, and by the off-line valve and exhaust pipe into the atmosphere. With the filtration conditions, the dust on the filter bag accumulates more, when the resistance reaches a limited resistance (usually set to 1500Pa), by the cleaning control device by the differential pressure set value or cleaning time Set the value of automatically close a room off the valve, according to set the program to open the electronic control pulse valve, the air blows, the use of compressed air instantly blows the pressure inside the bag to increase the dust on the filter bag to shake off (Even if the sticky dust can be more thoroughly cleaned) to the hopper, discharged by the ash discharge mechanism.
LFEF dryer series fiberglass generation of bag filter is designed for ￠1.5
* 12 m, ￠1.5 * 15 m and 12 m, ￠2.4 ￠2.2 x x 16 m and other specifications of the
dryer flue gas dust removal developed new products, the product is for the 1989
annual ministry of science and technology progress prize of shaft kiln glass
fiber bag dust removal technology, microcomputer control chamber blow, timing,
resistance shows such as soot, temperature detection, make glass fiber bag
precipitator in dryers dust removal efficiency, stable operation, the chimney
outlet concentration below 150 mg/nm3 emissions standards stipulated by the
state (the actual can guarantee 100 mg/nm3) or less.The device can not stop
chamber in bag, simple operation, safe and reliable, low operating cost, is the
most ideal equipment at present domestic dryers dust removal.
LFEF series of glass fiber filter bag is designed for ￠ 1.5 × 12M, ￠ 1.5 × 15M, ￠ 2.2 × 12M, ￠ 2.4 × 16M and other specifications of the dryer flue gas dust developed the development of new products, the product The use of access to the 1989 Ministry of Science and Technology Progress Award kiln glass fiber bag dust removal technology: microcomputer control sub-room backflush, timing, fixed resistance ash, temperature detection display, so that the glass bag filter in the drying Flue gas dust in the efficient and stable operation, chimneys export emissions below the national standard of 150mg / nm3 emission standards (actually can guarantee ≤ 100mg / nm3). The equipment can be non-stop sub-room for bags, simple operation, safe and reliable, low operating costs, is the current domestic dryer dust desulfurization the best equipment.
