Pulse jet bag dust collector is composed of the following parts:

Shell part: including cleaning room (or gas purification box, the box), filtering room, compartment partition, access door and shell structure. The cleaning room is equipped with lifting valve and flower plate, blowing short pipe: the filter room is equipped with filter and its skeleton.

Ash hopper and ash unloading mechanism: there are ash hopper and according to different series, different dust concentration, respectively set up screw conveyor, air conveying inclined chute and rigid impeller unloader (ash unloading valve).

Inlet and outlet air box: including inlet and outlet air pipeline and centre partition. Single-row (or single-row) structure is arranged on one side of the shell, double-row (or double-row) structure is arranged in the middle of the shell.

Pulse ash cleaning device: including pulse valve, air bag, lifting valve cylinder and its solenoid valve.

Compressed air pipeline and pressure reducing device, oil-water separator, oil mist, etc..

Pulse jet Baghouse Dust Collector is when the dusty gas enters into the dust collector from the air inlet, and touches the inclined plate and baffle plate in the middle of the air inlet and outlet, then the gas flow will turn to flow into the dust hopper, and at the same time, the gas flow slows down, and due to the inertial effect, the coarse particles of dust in the gas flow into the dust hopper directly. Pre-collection of dust, into the dust hopper of the gas flow followed by folding and up through the interior equipped with a metal skeleton of the filter bag dust is arrested in the outer surface of the filter bag, after purification of the gas into the filter bag room clean room, convergence to the outlet discharge, dusty gas purification process through the filter bag, with the increase in time and the accumulation of dust attached to the filter bag more and more to increase the resistance of the filter bag, resulting in the processing of air volume gradually reduced for the normal operation, to control the resistance of the filter bag to the filter bag to the filter bag. Normal work, to control the resistance within a certain range (140 - 170 mm water column), once more than the scope of the filter bag for cleaning, cleaning by the pulse controller sequentially triggered by the control valve to open the pulse valve, the compressed air from the airbag blowing tube holes through the Vinzel tube jet to the corresponding filter bag, the filter bag instantaneous and rapid expansion, so that the accumulation of dust attached to the surface of the filter bag fall off, the filter bag to return to the initial state. The dust falls into the ash hopper and is discharged from the machine through the ash discharge system. Thus, the dust accumulated on the filter bag is periodically pulse blown to clear the dust, pulse jet bag filter so that the purified gas passes through normally, to ensure the operation of the dust removal system.

Pulse jet bag dust collector refers to the method of removing the dust attached to the filter medium (bag or cartridge) by blowing compressed air; according to the size of the pulse jet bag dust collector, there may be several sets of pulse valves, controlled by the pulse controller or PLC, each time to open a set of pulse valves to remove the dust of the part of the bag or cartridge that it controls, and the other bag or cartridge work normally, after a period of time the next set of pulse valves open to clean up the next part of the dust collector by After a period of time, the next set of pulse valves will be opened to clean the next part of the dust collector, which consists of dust hopper, upper box, middle box, lower box and so on, and the upper, middle and lower boxes are divided into chambers. When working, the dusty gas enters into the dust hopper from the inlet duct, the coarse dust particles fall into the bottom of the dust hopper directly, the fine dust particles enter into the middle and lower box with the airflow turning upwards, the dust accumulates on the outer surface of the filter bag, the filtered gas enters into the upper box to the clean gas collection pipe - exhaust duct, through the exhaust fan to the atmosphere. Cleaning process is to cut off the clean gas outlet duct of the room first, so that the bag in the room is in the state of no airflow through the state (room air cleaning). Then open the pulse valve with compressed air pulse blowing cleaning, cut off the valve closure time is enough to ensure that after blowing from the filter bag on the stripping of dust settling to the dust hopper, to avoid the dust in the surface of the filter bag and then with the airflow attached to the neighbouring filter bag surface of the phenomenon, so that the filter bag clearing thoroughly, and by the programmable programmable control instrument on the exhaust valve, the pulse valve and the ash removal valve, etc., for fully automatic control. The dusty gas enters through the air inlet, and when it passes through the grey hopper, some of the large particles of dust in the gas are separated by inertial force and gravity, and fall into the bottom of the grey hopper directly. The dusty gas passes through the grey hopper and enters the filter bag filtration area in the middle box, the gas passes through the filter bag, the dust is blocked on the outer surface of the filter bag, and the purified gas enters the upper box through the filter bag mouth, and then is discharged from the air outlet.
