布袋除塵器可以處理多種類(lèi)型的粉塵，對于一些特殊的粉塵也可以得到很好的處理效果。比如高溫粉塵，有粘度的粉塵，潮濕的粉塵等。當然對于處理特殊情況的粉塵布袋除塵器在處理過(guò)程中也是要特別注意的。下面我們就針對潮濕工況的粉塵布袋除塵器如果進(jìn)行處理做一下詳細的介紹。

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.

布袋除塵器潮濕粉塵的注意事項：

Precautions for using bag filter to solve humid dust:

1）布袋除塵器清灰有足夠的反吹壓力：進(jìn)入濾袋的石灰粉塵可以通過(guò)反吹進(jìn)行清理，足夠的壓力由利于清理濾料中的粉塵。

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）石灰粉袋式除塵器配有穩定的旁通管：當空氣相對濕度增加時(shí)，進(jìn)入除塵系統的含塵空氣容易冷凝。為了防止濕氣進(jìn)入袋式除塵器并粘結過(guò)濾材料，應設置穩定的旁通管。此時(shí)，可避免使用袋式除塵器，使含塵空氣只能通過(guò)1級旋風(fēng)分離器，然后排放到大氣中。

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）小心使用除塵布袋：應選用不易粘在湖面上的光滑除塵布袋，如光滑聚酯濾料729、針氈除塵布袋等。

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）布袋除塵器清灰周期短：清灰周期短，有利于及時(shí)清理布袋表面的石灰粉塵，減少粘結的可能性。

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）布袋除塵器低過(guò)濾風(fēng)速：高過(guò)濾風(fēng)速會(huì )迫使細石灰粉塵進(jìn)入內部鋸齒狀微孔堵塞。當反吹失敗時(shí)，它將在濾袋中停留很長(cháng)時(shí)間，并形成粘合劑堵塞過(guò)濾孔。采用低過(guò)濾風(fēng)速可避免上述缺點(diǎn)。

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.
