过滤原理：含尘气体由进风口进入，经过灰斗时，气体中部分大颗粒粉尘受惯性力和重力作用被分离出来，直接落入灰斗底部。含尘气体通过灰斗后进入中箱体的滤袋过滤区，气体穿过滤袋，粉尘被阻留在滤袋外表面，净化后的气体经滤袋口进入上箱体后，再由出风口排出。

Filtering principle: Dust containing gas enters through the air inlet, and when passing through the ash hopper, some large particles of dust in the gas are separated by inertia and gravity, and directly fall into the bottom of the ash hopper. Dust containing gas enters the filter bag filtration area of the middle box after passing through the ash hopper. The gas passes through the filter bag and the dust is trapped on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag mouth and is then discharged through the air outlet.

清灰原理：随着过滤时间的延长，滤袋上的粉尘层不断积厚，除尘设备的阻力不断上升，当设备阻力上升到设定值时，清灰装置开始进行清灰。一个分室提升阀关闭，将过滤气流截断，然后电磁脉冲阀开启，压缩空气以极短促的时间在上箱体内迅速膨胀，涌入滤袋，使滤袋膨胀变形产生振动，并在逆向气流冲刷的作用下，附着在滤袋外表面上的粉尘被剥离落入灰斗中。清灰完毕后，电磁脉冲阀关闭，提升阀打开，该室始为一个清灰周期。又恢复过滤状态。清灰各室依次进行，从室清灰开始一次清灰开

Ash cleaning principle: With the extension of filtration time, the dust layer on the filter bag continues to accumulate, and the resistance of the dust removal equipment continues to rise. When the resistance of the equipment rises to the set value, the ash cleaning device begins to clean the dust. Firstly, a chamber lifting valve is closed to cut off the filtered airflow, and then the electromagnetic pulse valve is opened. Compressed air rapidly expands in the upper chamber in a very short time, flowing into the filter bag, causing it to expand and deform, resulting in vibration. Under the action of reverse airflow erosion, the dust attached to the outer surface of the filter bag is peeled off and falls into the ash hopper. After the cleaning is completed, the electromagnetic pulse valve closes and the lifting valve opens, and the room begins a cleaning cycle. Restore filtering status again. The cleaning process is carried out sequentially in each room, starting from the first room and continuing until the first cleaning operation

粉尘收集：经过滤和清灰工作被截留下来的粉尘均落入灰斗，再由灰斗口集中排出

Dust collection: The dust intercepted by filtration and cleaning work falls into the ash hopper and is then centrally discharged through the ash hopper mouth
