Pulse bag dust removal project
Advantage of long pulse pulse bag filter:
1., high efficiency, dust collection rate of 99%, dust collection can be less than 5um;
2., the internal use of pulse dedicated pleated filter cartridge, compact structure, tower design beautiful, general, small footprint;
3. special bag: oil proof, waterproof and antistatic;
4. Star automatic feeding valve, easy to operate, safe and reliable;
5., battery valve selection Taiwan Hui brand, durable (720 times a day can work continuously), not hot, waterproof, lightning protection, safe and reliable;
6., the equipment has good protection performance, can adapt to the harsh working environment and wide range of applications;
I. overview of pulse dust collector:
Pulse bag filter is a dry dust removal device, also known as the filter type dust collector, it is dust collector bag type filter element using fiber fabric made to capture solid particles of dust in the gas, its principle is dust in via the cloth fiber due to inertia effect and fiber contact and be intercepted, the bag on the dust collected by regularly cleaning device removed and then discharged into ash hopper, through the ash removal system.
First, Dragon Environmental Protection pulse bag filter definition:
Pulse bag filter with compressed air for cleaning power, the pulse blowing mechanism in the instant release of compressed air, the two air bag induced by high speed into several times, so that the bag has swollen on impulse and reverse flow and clear baghouse ash.
Purification equipment pulse filter a new high efficient dust removal, the cleaning method of low pressure pulse jet, and also has good cleaning effect, high purification efficiency, the advantages of processing capacity, maintenance workload is small, safe and reliable operation etc.. Pulse bag filter dust removal can be widely used in hardware, building materials, cement, ceramics, electronics, chemical, shoe, casting, plastic, aluminum products, electric power, metallurgy, leather, food processing machinery, nonferrous metals, various industrial fields such as purification.
Two. The working principle of pulse bag filter
Dusty gas from the upper part of the ash hopper inlet into the windscreen, under the action of air flow upward flow is reduced, partly due to inertia of large particles of dust are separated from the ash hopper, dust laden gas into the box in the bag filter, dust by the outer surface resistance in the bag, the purified gas the filter bag into the upper box is out from the outlet.
As the dust on the filter bag surface increases continuously, the pressure difference between the inlet and outlet of the dust collector also increases. When the resistance of the dust collector reaches a set value, the control system issues ash cleaning instructions, and the ash cleaning system starts to work.
First, the electromagnetic valve opens immediately after receiving the signal, the small upper part of the diaphragm chamber of the compressed air is discharged, due to the small diaphragm force change ends, the small diaphragm closes the exhaust passage opening, large diaphragm upper air chamber of compressed air discharged by the passage, so that both ends of the large diaphragm stress change, the diaphragm moves. The closure of the output port to open, compressed air in the air bag through the output pipe and nozzle spray into the bag, to achieve cleaning. When the control signal is stopped, the electromagnetic valve is closed, and the small diaphragm and the large diaphragm are reset successively, and the spraying is stopped. By shake off the dust falling into the ash bucket, ash valve through the discharge machine.

Advantages of long pulse pulse bag filter:
The high dust removal efficiency, can capture fine dust particles larger than 0.3 microns, the dust removal efficiency can reach more than 99%;
The use of flexible, air volume by millions of cubic meters per hour to hundreds of thousands of cubic meters, can be directly arranged on the indoor machine near a small unit, but also can be made into a large dust collector;
It has the advantages of simple structure, stable operation, convenient maintenance.
Applicable range of pulse bag filter:
The pulse dust remover is widely used in purification of hardware, building materials, cement dust, ceramics, electronics, chemical, shoe, casting, plastic, aluminum products, electric power, metallurgy, leather, food, machinery, non-ferrous metals and other industrial fields.
