High efficiency pulse bag filter BH industrial dust collector
Description:
The pulse dust collector is a new high-efficiency
pulse dust collector improved on the basis of bag filter. It
combines the advantages of sub-chamber back-blowing various pulse
jet dust collectors, and overcomes the shortcomings of insufficient
chamber dust-removing strength and uneven distribution of inlet and
outlet winds. Expanded the scope of application.
The pulse dust collector is when the dust-containing
gas enters the dust collector from the air inlet, first hits the
sloping plate and the baffle in the middle of the air inlet and
outlet, the air flow turns into the ash hopper, and the air flow
speed is slowed down, and the coarse particles in the gas are
caused by the inertia. The dust flows directly into the ash bucket.
As a function of pre-collection, the airflow entering the ash
bucket is then folded upwards and collected through the filter bag
dust containing the metal skeleton inside, and is collected on the
outer surface of the filter bag, and the purified gas enters the
upper cleaning chamber of the filter bag chamber, and is collected.
When the tuyere is discharged and the dust-containing gas is
purified through the filter bag, the dust accumulated on the filter
bag increases with time, increasing the resistance of the filter
bag, causing the treatment air volume to gradually decrease, for
normal work, to be controlled. The resistance is within a certain
range (140--170 mm water column). Once the range is exceeded, the
filter bag must be cleaned. When the dust is cleaned, the pulse
control device sequentially triggers each control valve to open the
pulse valve. The compressed air in the air bag is blown by the
blowing pipe. Each hole is sprayed into each corresponding filter
bag through the venturi tube, and the filter bag is suddenly
expanded rapidly, so that the dust accumulated on the surface of
the filter bag is detached, and the filter bag is restored to its
original shape. The dust falls into the ash bucket and is
discharged through the ash discharge system. Thereby, the dust
accumulated on the filter bag is periodically pulsed and cleaned,
so that the purge gas passes normally, and the dust removal system
is operated.

Application:
The pulse dust collector adopts the off-line off-line pulse cleaning technology to overcome the shortcomings of anti-air cleaning and general pulse cleaning. It has strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate and low energy consumption. Less, the operation is reliable and stable. This series of dust collectors is especially suitable for the following occasions: dust removal in calcium carbide furnaces, dust removal in various electric furnaces in iron alloy plants; flue gas purification in steel plants; dust removal in small boilers for coal-fired boilers and power plants; dust removal in waste incinerators; high-temperature flue gas dedusting in smelters; Flue gas purification; cement plant rotary kiln kiln tail, kiln head dust removal; carbon black plant exhaust gas dust removal. Its application area is characterized by high temperature and large smoke volume.
Trouble shooting method:
| Malfunction | Reasons | Remedy |
| Large running resistance | 1 filter bag knot; 2 pulse valve does not work or damage; 3 compressed air pressure is too low; 4 pulse valve operation when the poppet valve is not closed; 5 one or more poppet valves are closed | 1 clean the filter bag, strengthen ventilation; 2 maintain or replace the pulse valve; 3 check the gas circuit and air compressor; 4 check the cleaning controller |
| small running resistance | 1 smoke short circuit; 2 filter bag breakage
| 1 Check the pipeline and repair the damage; 2 Check and replace the filter bag |
| The pulse valve does not work | 1 power failure or cleaning controller failure; 2 pulse valve has debris, has been leaking; 3 pulse valve coil burned; 4 compressed air pressure is too low | 1 restore power supply or repair the cleaning controller; 2 carefully clean the pulse valve; 3 replace the pulse valve coil; 4 check the pneumatic system and compressor |
