負壓組合除塵器是一種常見的工業煙塵處理設備，其工作原理主要涉及負壓吸引、氣體過濾和灰塵收集三個方面

　　The negative pressure combined dust collector is a common industrial smoke and dust treatment equipment, and its working principle mainly involves three aspects: negative pressure suction, gas filtration, and dust collection.

　　，通過風機產生負壓效應，將含有粉塵顆粒的廢氣吸入到負壓除塵器內部。

　　Firstly, the negative pressure effect is generated by the fan, which sucks the exhaust gas containing dust particles into the interior of the negative pressure dust collector.

　　其次，廢氣經過預處理后，進入到過濾室。在過濾室內設置了一系列過濾裝置，如濾筒、濾袋、過濾板等，這些過濾裝置具有多孔結構或纖維材料，能夠有效地阻攔和截留粉塵顆粒。當廢氣通過過濾裝置時，較大顆粒的塵埃會被直接阻攔在過濾裝置表面，而微小顆粒的塵埃會因空氣流動而懸浮在空氣中。

　　Secondly, after pre-treatment, the exhaust gas enters the filtration chamber. A series of filtration devices, such as filter cartridges, filter bags, filter plates, etc., are installed in the filtration room. These filtration devices have porous structures or fiber materials that can effectively block and intercept dust particles. When the exhaust gas passes through the filtering device, larger particles of dust will be directly blocked on the surface of the filtering device, while smaller particles of dust will be suspended in the air due to air flow.

　　，經過過濾后的相對潔凈的氣體進入出口處，而被截留下來的灰塵顆粒則通過定期清灰操作進行收集和處理。清灰操作可以采用物理方法（如震動、沖擊等）或化學方法（如噴水洗滌）來將灰塵顆粒從過濾裝置中，然后將其輸送到灰塵收集倉或其他處理設備中進行后續處理。

　　Finally, the relatively clean gas after filtration enters the outlet, while the intercepted dust particles are collected and processed through regular cleaning operations. The dust removal operation can use physical methods (such as vibration, impact, etc.) or chemical methods (such as water spray washing) to remove dust particles from the filtering device, and then transport them to the dust collection bin or other processing equipment for subsequent processing.

　　通過以上的工作原理，負壓組合除塵器能夠有效地去除廢氣中的粉塵顆粒，保障環境的清潔和生產過程的正常進行。同時，為了保證除塵效果和設備的可靠性，還需要對除塵器進行定期的檢修和維護。。

　　Based on the above working principles, the negative pressure combined dust collector can effectively remove dust particles in the exhaust gas, ensuring the cleanliness of the environment and the normal operation of the production process. At the same time, in order to ensure the dust removal effect and equipment reliability, it is also necessary to regularly inspect and maintain the dust collector..
