布袋除尘器可以处理多种类型的粉尘，对于一些特殊的粉尘也可以得到很好的处理效果。比如高温粉尘，有粘度的粉尘，潮湿的粉尘等。当然对于处理特殊情况的粉尘布袋除尘器在处理过程中也是要特别注意的。下面我们就针对潮湿工况的粉尘布袋除尘器如果进行处理做一下详细的介绍。

Bag dust collectors can handle various types of dust, and can also achieve good treatment results for some special types of dust. For example, high-temperature dust, sticky dust, humid dust, etc. Of course, special attention should also be paid to the dust bag filter in handling special situations during the processing. Below, we will provide a detailed introduction to the treatment of dust bag filters under humid working conditions.

布袋除尘器潮湿粉尘的注意事项：

Precautions for using bag filter to solve humid dust:

1）布袋除尘器清灰有足够的反吹压力：进入滤袋的石灰粉尘可以通过反吹进行清理，足够的压力由利于清理滤料中的粉尘。

1) The bag filter has sufficient backflow pressure for dust removal: the lime dust entering the filter bag can be cleaned by backflow, and sufficient pressure is conducive to cleaning the dust in the filter material.

2）石灰粉袋式除尘器配有稳定的旁通管：当空气相对湿度增加时，进入除尘系统的含尘空气容易冷凝。为了防止湿气进入袋式除尘器并粘结过滤材料，应设置稳定的旁通管。此时，可避免使用袋式除尘器，使含尘空气只能通过1级旋风分离器，然后排放到大气中。

2) The lime powder bag filter is equipped with a stable bypass pipe: when the relative humidity of the air increases, the dusty air entering the dust removal system is prone to condensation. To prevent moisture from entering the bag filter and bonding the filter material, a stable bypass pipe should be installed. At this point, the use of bag filters can be avoided, allowing dusty air to only pass through the first stage cyclone separator and then be discharged into the atmosphere.

3）小心使用除尘布袋：应选用不易粘在湖面上的光滑除尘布袋，如光滑聚酯滤料729、针毡除尘布袋等。

3) Be careful when using dust removal bags: Smooth dust removal bags that are not easily adhered to the lake surface should be selected, such as smooth polyester filter material 729, needle felt dust removal bags, etc.

4）布袋除尘器清灰周期短：清灰周期短，有利于及时清理布袋表面的石灰粉尘，减少粘结的可能性。

4) Short cleaning cycle of bag filter: The short cleaning cycle is conducive to timely cleaning of lime dust on the surface of the bag, reducing the possibility of adhesion.

5）布袋除尘器低过滤风速：高过滤风速会迫使细石灰粉尘进入内部锯齿状微孔堵塞。当反吹失败时，它将在滤袋中停留很长时间，并形成粘合剂堵塞过滤孔。采用低过滤风速可避免上述缺点。

5) Low filtration wind speed of bag filter: High filtration wind speed will force fine lime dust to enter the internal serrated micropores and block them. When the backwash fails, it will stay in the filter bag for a long time and form adhesive to block the filter holes. The use of low filtering wind speed can avoid the above drawbacks.
