负压组合除尘器是一种常见的工业烟尘处理设备，其工作原理主要涉及负压吸引、气体过滤和灰尘收集三个方面

　　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.

　　首先，通过风机产生负压效应，将含有粉尘颗粒的废气吸入到负压除尘器内部。

　　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，废气经过预处理后，进入到过滤室。在过滤室内设置了一系列过滤装置，如滤筒、滤袋、过滤板等，这些过滤装置具有多孔结构或纤维材料，能够有效地阻拦和截留粉尘颗粒。当废气通过过滤装置时，较大颗粒的尘埃会被直接阻拦在过滤装置表面，而微小颗粒的尘埃会因空气流动而悬浮在空气中。

　　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.

　　最后，经过过滤后的相对洁净的气体进入出口处，而被截留下来的灰尘颗粒则通过定期清灰操作进行收集和处理。清灰操作可以采用物理方法（如震动、冲击等）或化学方法（如喷水洗涤）来将灰尘颗粒从过滤装置中清除，然后将其输送到灰尘收集仓或其他处理设备中进行后续处理。

　　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.

　　通过以上的工作原理，负压组合除尘器能够有效地去除废气中的粉尘颗粒，保障环境的清洁和生产过程的正常进行。同时，为了保证除尘效果和设备的可靠性，还需要对除尘器进行定期的检修和维护。。

　　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..
