過濾原理：含塵氣體由進(jìn)風(fēng)口進(jìn)入，經(jīng)過灰斗時(shí)，氣體中部分大顆粒粉塵受慣性力和重力作用被分離出來，直接落入灰斗底部。含塵氣體通過灰斗后進(jìn)入中箱體的濾袋過濾區(qū)，氣體穿過濾袋，粉塵被阻留在濾袋外表面，凈化后的氣體經(jīng)濾袋口進(jìn)入上箱體后，再由出風(fēng)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：隨著過濾時(shí)間的延長，濾袋上的粉塵層不斷積厚，除塵設(shè)備的阻力不斷上升，當(dāng)設(shè)備阻力上升到設(shè)定值時(shí)，清灰裝置開始進(jìn)行清灰。首先一個(gè)分室提升閥關(guān)閉，將過濾氣流截?cái)?，然后電磁脈沖閥開啟，壓縮空氣以極短促的時(shí)間在上箱體內(nèi)迅速膨脹，涌入濾袋，使濾袋膨脹變形產(chǎn)生振動，并在逆向氣流沖刷的作用下，附著在濾袋外表面上的粉塵被剝離落入灰斗中。清灰完畢后，電磁脈沖閥關(guān)閉，提升閥打開，該室始為一個(gè)清灰周期。又恢復(fù)過濾狀態(tài)。清灰各室依次進(jìn)行，從第一室清灰開始至一次清灰開

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

粉塵收集：經(jīng)過濾和清灰工作被截留下來的粉塵均落入灰斗，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
