Filter cartridge dust collector
Under the action of the main fan of the system, the dust-containing gas enters the air box at the bottom of the dust collector from the air inlet of the lower part of the dust collector to pre-treat the dust-containing gas, and then enters into the dust-removing chamber of the upper tank from the bottom; dust adsorption On the outer surface of the filter cartridge, the filtered clean gas permeates through the filter cartridge into the clean air chamber of the upper tank and is collected and discharged to the air outlet.
As the filtration conditions continue, the dust accumulated on the outer surface of the filter cartridge will accumulate more and more, which will increase the running resistance of the equipment. In order to ensure the normal operation of the system, the upper limit of the dust collector resistance should be maintained in the range of 1400-1600Pa. Within this limit, the three-state cleaning should be performed by the PLC pulse automatic controller through a fixed resistance or a timing command.
The cleaning process of the filter cartridge type dust remover is to cut off the clean air outlet passage of a certain chamber, so that the chamber is in a state of airflow still state, and then the compressed air pulse is blown back to clean the dust, and after a few seconds of cleaning. After the natural settlement, the clean air outlet passage of the chamber is opened, not only the ash is completely cleaned, but also the secondary adsorption of the dust generated by the spray cleaning is avoided, so that the chamber is circulated and cleaned.
Multi-tube dust collector
The dust-laden gas enters the gas distribution chamber from the total intake pipe and then enters the annular space between the ceramic cyclone body and the baffle. The deflector changes the gas from a linear motion to a circular motion. The majority of the swirling airflow spirals downward from the cylinder to the cone, and the dust-containing gas generates centrifugal force during the rotation, which is greater than the density. The dust particles of the gas smash toward the wall of the cylinder. When the dust particles are in contact with the wall of the cylinder, the inertia force is lost and the momentum of the inlet velocity and the downward gravity fall down the wall toward the ash discharge port into the total ash hopper. When the rotating external swirling airflow reaches the lower end of the cone, the conical body continues to make a spiral flow (purifying air) from the bottom to the top in the direction of the cyclone axis due to the contraction of the cone, and passes through the ceramic cyclone exhaust pipe. Enter the exhaust chamber and discharge from the total exhaust port.
