With the vigorous implementation of environmental protection policy, cement tanks manufactured by cement tank manufacturers are equipped with dust collectors. Of course, different types of dust collectors have different effects. Pulse dust collector is a large amount of dust removal equipment, this paper expounds the factors that affect the pressure of the dust removal system of the pulse dust collector of the concrete mixer.

脉冲水泥罐顶除尘器的清灰系统中清灰压力是设计的重要参数。区分成高压、中压和低压。根据气包内压力，清灰系统脉冲阀可分成高压阀和低压阀。

The cleaning pressure is an important parameter in the design of the cleaning system of the pulse cement tank top dust collector. It is divided into high pressure, medium pressure and low pressure. According to the pressure in the air bag, the pulse valve of ash cleaning system can be divided into high pressure valve and low pressure valve.

脉冲袋式除尘器主要是以压力气包内压缩气作为清灰能源，使脉冲阀启动时形成一股脉冲气流逆向从滤袋顶部到袋底进行脉冲抖动。通过脉冲喷吹抖动，把滤袋外侧结合的尘层抖进除尘器灰斗。

The pulse bag filter mainly uses the compressed gas in the pressure air bag as the energy source of ash cleaning, which makes a pulse air flow formed when the pulse valve starts up and vibrates reversely from the top of the filter bag to the bottom of the filter bag. Through pulse injection shaking, the combined dust layer outside the filter bag is shaken into the dust hopper of the dust collector.

如果压力或流量不足，这个气流太弱，那么清灰粒度不能再在到滤袋底部，则尘层不能及时剥落，造成局部积灰，就会导致设备阻力增高、滤袋负荷不均匀等现象，缩短滤袋寿命。

If the pressure or flow is insufficient and the air flow is too weak, the ash cleaning particle size can no longer reach the bottom of the filter bag, and the dust layer can not peel off in time, resulting in local ash accumulation, which will lead to increased equipment resistance, uneven load of the filter bag, and shorten the service life of the filter bag.

反之，如果清灰力度太强，已经渗透进滤料表层的微细颗粒将被吹出表面，产生“二次扬尘”现象。由此滤袋也可能因震荡力太强导致与笼骨的摩擦过高而裂袋。

On the contrary, if the dust removal force is too strong, the fine particles that have penetrated into the surface of the filter material will be blown out of the surface, resulting in "secondary dust" phenomenon. As a result, the bag may crack due to the high friction between the bag and cage bone.

总之，除尘清灰系统的压力必须根据工艺、烟尘和滤料的性质而合理配置。不能用单一清灰压力所有除尘问题。更多有关混凝土搅拌机设备的详细信息可以直接关注：http://www.zkhntjbc.com

In a word, the pressure of dust removal system must be reasonably allocated according to the process, the nature of dust and filter material. All dust removal problems can not be solved by single dust removal pressure. For more details about concrete mixer equipment, you can directly pay attention to: http://www.zkhntjbc.com
