车间整体除尘设备的工作原理

Working principle of the overall dust removal equipment in the workshop

　　除尘器的工作原理如下：含尘气体由下部敞开式法兰进入过滤室，较粗颗粒直接落入灰仓，含尘气体经滤袋过滤，粉尘阻留于袋表，净气经袋口到净气室，由风机排入大气。当滤袋表面的粉尘不断增加，程控仪开始工作，逐个开启脉冲阀，使压缩空气通过喷口对滤袋进行喷吹清灰，使滤袋突然膨胀，在反向气流的作用下，赋予袋表的粉尘迅速脱离滤袋落入灰仓，粉尘由卸灰阀排出。

The working principle of a dust collector is as follows: the dusty gas enters the filter chamber through the lower open flange, and the coarser particles directly fall into the ash bin. The dusty gas is filtered by the filter bag, and the dust is trapped on the bag surface. The clean gas is then transported to the clean gas chamber through the bag mouth and discharged into the atmosphere by a fan. When the dust on the surface of the filter bag continues to increase, the programmable controller begins to work. Pulse valves are opened one by one, allowing compressed air to spray and clean the dust on the filter bag through the nozzle, causing the filter bag to suddenly expand. Under the action of reverse airflow, the dust on the bag surface quickly separates from the filter bag and falls into the ash bin, and the dust is discharged by the ash discharge valve.

　　滤筒除尘器工作原理：含尘气体进入除尘器灰斗后，由于气流断面突然扩大及气流分布板作用，气流中一部分粗大颗粒在动和惯性力作用下沉降在灰斗；粒度细、密度小的尘粒进入滤尘室后，通过布袋扩散和筛滤等组合效应，使粉尘沉积在滤袋表面上，净化后的气体进入净气室由排气管经风机排出。

Working principle of filter cartridge dust collector: After the dusty gas enters the ash hopper of the dust collector, due to the sudden expansion of the airflow cross-section and the action of the airflow distribution plate, some coarse particles in the airflow settle in the ash hopper under the action of dynamic and inertial forces; After the fine particle size and low density dust particles enter the dust filter room, they are combined with bag diffusion and screening to deposit the dust on the surface of the filter bag. The purified gas enters the clean air chamber and is discharged by the exhaust pipe and fan.

　　滤筒式除尘器的阻力随滤袋表面粉尘层厚度的增加而增大。阻力达到某一规定值时进行清灰。此时程序控制电磁脉冲阀的启闭，首先一分室提升阀关闭，将过滤气流截断，然后电磁脉冲阀开启，压缩空气以及短的时间在上箱体内迅速膨胀，涌入滤筒，使滤筒膨胀变形产生振动，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。

The resistance of the filter cartridge dust collector increases with the increase of the thickness of the dust layer on the surface of the filter bag. Clean the dust when the resistance reaches a certain specified value. At this point, the program controls the opening and closing of the electromagnetic pulse valve. Firstly, the lifting valve of the first chamber is closed to cut off the filtered air flow. Then, the electromagnetic pulse valve is opened, and compressed air and a short period of time rapidly expand inside the upper chamber, flowing into the filter cartridge, causing the filter cartridge 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.

　　清灰完毕后，电磁脉冲阀关闭，提升阀打开，该室又恢复过滤状态。清灰各室依次进行，从第一室清灰开始至下一次清灰开始为一个清灰周期。脱落的粉尘掉入灰斗内通过缷灰阀排出。

After the ash cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the room returns to the filtering state. The cleaning process is carried out sequentially in each room, with one cleaning cycle from the first cleaning to the next cleaning. The detached dust falls into the ash hopper and is discharged through the ash discharge valve.
