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.

脈沖水泥罐頂除塵器的清灰系統中清灰壓力是設計的重要參數。區分成高壓、中壓和低壓。根據氣包內壓力，清灰系統脈沖閥可分成高壓閥和低壓閥。

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.

脈沖袋式除塵器主要是以壓力氣包內壓縮氣作為清灰能源，使脈沖閥啟動時形成一股脈沖氣流逆向從濾袋頂部到袋底進行脈沖抖動。通過脈沖噴吹抖動，把濾袋外側結合的塵層抖進除塵器灰斗。

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.

如果壓力或流量不足，這個氣流太弱，那么清灰粒度不能再在到濾袋底部，則塵層不能及時剝落，造成局部積灰，就會導致設備阻力增高、濾袋負荷不均勻等現象，縮短濾袋壽命。

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，如果清灰力度太強，已經滲透進濾料表層的微細顆粒將被吹出表面，產生“二次揚塵”現象。由此濾袋也可能因震蕩力太強導致與籠骨的摩擦過高而裂袋。

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.

總之，除塵清灰系統的壓力必須根據工藝、煙塵和濾料的性質而合理配置。不能用單一清灰壓力解決所有除塵問題。更多有關混凝土攪拌機設備的詳細信息可以直接關注：http://www.thecxg.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.thecxg.com
