The structure of a filter cartridge dust collector consists of an inlet duct, an exhaust duct, a box, an ash hopper, a cleaning device, a guide device, an airflow distribution plate, a filter cartridge, and an electrical control device, similar to the structure of an air box pulse bag dust collector.

The arrangement of the filter cartridge in the dust collector is very important. It can be vertically arranged on the box flower board or tilted on the flower board. From the perspective of dust cleaning effect, vertical arrangement is more reasonable. The lower part of the flower board is the filtering chamber, and the upper part is the pulse chamber of the air box. An airflow distribution plate is installed at the inlet of the dust collector.

Dust cleaning device

Traditional filter cartridge dust collectors have two cleaning methods, one is high-pressure air flow back blowing, and the other is pulse air flow blowing. Practice has shown that the former has the advantage of uniform air flow, but the disadvantage is high air consumption; The advantage of the latter is low gas consumption, but the disadvantage is weak airflow. Two improvements can be made for this: on the one hand, a guide device can be added to the pulse blowing tube to enhance the airflow induction effect, and on the other hand, the upper guide duct of the filter cartridge can be removed to allow both pulse airflow and induced airflow to fully enter the filter cartridge at the same time. After this improvement, the air consumption is reduced, the airflow is uniform, and the dust cleaning effect is good. According to calculations, the dust cleaning airflow flow rate after the technical improvement is 3-5 times that of the pulse airflow.

Gas distribution board

The airflow distribution of the filter cartridge dust collector is crucial, and it is important to consider how to avoid high wear areas on the filter material caused by high wind speeds at the equipment location. The airflow distribution plate is used for filter cartridge dust collectors with requirements for stable and uniform airflow distribution. It is beneficial for the increase of airflow and the decrease of dust, and the opening rate of the airflow distribution plate is 35%. According to calculations, the drag coefficient is less than or equal to; 2. It can be seen that when the airflow velocity is less than or equal to; At a speed of 0.8m/s, the porous airflow distribution plate can meet the requirements of the filter cartridge dust collector.
