With the continuous development of China's urban construction, construction machinery industry has also been developed, the demand for commercial concrete is also increasing, investors mixing station users are also increasing, but the concrete mixer dust removal system is not ideal, dust removal system problems, dust pollution will become serious, so what are the problems of dust removal system?

目前，混凝土搅拌机主体部分的除尘系统广泛采用的是脉冲反吹式除尘器，将高压空气以脉冲方式周期间歇式地吹入滤芯内部，将粘附在滤芯外表面的灰尘吹落。这种除尘机的除尘效率很高，但前提是能够真正地将粘附在滤芯外表面的灰尘吹落，否则，即便是除尘效率再高，也会产生严重的粉尘污染。

At present, the main part of the concrete mixer dust removal system is widely used pulse back blowing dust collector, high-pressure air is blown into the filter element intermittently in pulse mode, and the dust adhering to the outer surface of the filter element is blown off. The dust removal efficiency of this kind of dust remover is very high, but the premise is that the dust adhering to the outer surface of the filter element can be blown off. Otherwise, even if the dust removal efficiency is higher, serious dust pollution will be produced.

许多厂家为了节省成本，直接将搅拌机的引风管接在除尘机积尘料仓的下方，是滤芯始终处于潮湿灰尘的包围之中，打打降低了除尘系统的除尘效率。

In order to save the cost, many manufacturers directly connect the induced draft pipe of the mixer to the bottom of the dust storage bin of the dust collector, so that the filter element is always surrounded by wet dust, which reduces the dust removal efficiency of the dust removal system.

多数厂家生产的除尘系统，都采用的是脉冲反吹的维护方式，是通过自带的控制器自动控制将高压空气以脉冲方式反吹滤芯，将粘附在滤芯外表面的灰尘吹落，这种情况可能会造成一边吹掉灰尘，一边又在吸附灰尘。

The maintenance mode of pulse back blowing is adopted in the dust removal system produced by most manufacturers. The self-contained controller automatically controls the high-pressure air to blow back the filter element in pulse mode, which will blow off the dust adhered to the outer surface of the filter element. This situation may cause dust to be blown off and absorbed at the same time.

除尘系统中存在的问题是会影响混凝土搅拌站的生产的，如果不达标就可能会面临停产的问题，因此，除尘系统在混凝土搅拌站中的作用影响还是比较大的。

The problems existing in the dust removal system will affect the production of the concrete mixing station. If the environmental protection is not up to standard, it may face the problem of production stop. Therefore, the effect of dust removal system in the concrete mixing station is still relatively large.
