鍋爐除塵器使用效果好壞和它的外殼設計也有重要關系。從材料本身來看，現在已經可以達到很高的效率，但是，往往由于鍋爐除塵器外殼設計不良，或者除塵器的布置、安裝存在缺點，以致灰塵不經過濾介質而旁通過去，造成不好的后果。 The use effect of the boiler dust collector and its shell design also has important relations. From the point of view of the material itself, now you can achieve very high efficiency, however, often because of poor design of the boiler precipitator shell, or dust collector arrangement, installation has some shortcomings, so that dust without filter media and bypass the past, resulting in bad consequences. 關于外殼設計的基本要求，有這樣一些: Basic requirements on the shell design, there are such a number of: (1)把鍋爐除塵器裝在外殼內，應當讓氣流通過過濾器的方向傾向于把過濾器向密封面壓緊。如果不能這樣做，就必須采取適當辦法把過濾器對著它的密封面夾緊,保證任何時候都不會松開。 (1) the boiler dust collector is installed in the housing, should let the air flow through the filter in the direction of the filter to the sealing surface. If you can not do so, you must take the appropriate approach to the filter facing its sealing surface, to ensure that no time will be released. (2)如果氣流是垂直經裝在外殼內的過濾器，通常應使空氣從上向下流動，因為這樣可以防止過濾器捕集的污染物在進行維修等工作時失落。 (2) if the air flow is a vertical filter installed in the enclosure, the air is normally to be made to flow downward from the air, as this prevents the filter from being lost when it is being repaired. (3)外殼應授有能聚集灰塵的突出面。 (3) the enclosure shall be granted with a prominent surface capable of gathering dust. (4)外殼折曲處應成圓弧狀，以免形成集聚灰塵的角落。所有內部焊接處，特別是密封面，均應磨光。 (4) the shell should flex arc shape, so as to avoid the formation of agglomeration of dust in the corner. All internal welds, especially the sealing surface, should be smooth. (5)外殼尺寸應當便于對過濾器進行維修等工作。這樣可能使鍋爐除塵器外殼體積稍大，但因維修方便，可以避免發生事故。 (5) the size of the enclosure shall facilitate the maintenance of the filter. This may cause the boiler dust collector shell size slightly larger, but the maintenance is convenient, can avoid the occurrence of accidents.
