粉尘除尘设备该选择哪样的除尘布袋较为合适呢?
Which dust bag is more suitable for dust removal equipment?
1、分室反吹类粉尘除尘设备
1. Dust removal equipment of chamber back blowing type
此类粉尘除尘设备属于低动能清灰类型,除尘布袋可选用薄型除尘布袋,如729,mp922等,这类除尘布袋质地轻柔,容易变形且尺寸稳定。对于分室反吹类粉尘除尘设备,无论是内滤还是外滤,除尘布袋的选用都无差异。大中型除尘器优先选用缎纹(或斜纹)机织除尘布袋,在特殊场合也可选用基布加强的薄型针毡除尘布袋。小型除尘器优先选用耐磨性,透气性好的薄型针毡除尘布袋,单位面积质量350~400g/m2,也可用纬二重或双重织物除尘布袋。
This kind of dust removal equipment belongs to the type of low kinetic energy dust removal. Thin dust removal bags can be selected, such as 729, mp922, etc., which are soft in texture, easy to deform and stable in size. There is no difference in the selection of dedusting cloth bag for indoor and outdoor reverse blowing dust dedusting equipment. Satin (or twill) woven dedusting cloth bag is preferred for large and medium-sized deduster, and thin needle felt dedusting cloth bag strengthened by base cloth can also be selected for special occasions. The thin needle felt dust bag with good wear resistance and air permeability is preferred for small dust remover. The unit area mass is 350-400g / m2, and the double weft or double fabric dust bag can also be used.

2、机械振打类粉尘除尘设备
2. Mechanical vibration dust removal equipment
此类粉尘除尘设备的特点是振动粉尘层的力量较小而次数较多,为使能量易于传播,保证过滤面上振击力足够,应该选择薄而光滑,质地柔软的除尘布袋。例如化纤缎纹或斜纹织物,厚度0.3~0.7mm,单位面积质量300~350g/m2,过滤速度0.6~1.0m/min,对小型除尘器机组可提高到1.0~1.5m/min。
This kind of dust removal equipment is characterized by small power and more times of vibrating dust layer. In order to make the energy easy to spread and ensure sufficient vibrating force on the filter surface, thin and smooth dust removal cloth bag with soft texture should be selected. For example, for chemical fiber satin or twill fabrics, the thickness is 0.3-0.7mm, the mass per unit area is 300-350g / m2, and the filtration speed is 0.6-1.0m/min, which can be increased to 1.0-1.5m/min for small dust remover units.
3、脉冲喷吹类粉尘除尘设备
3. Dust removal equipment of pulse injection type
此类粉尘除尘设备的除尘布袋选用原则与分室反吹类除尘器大体相同,以缎纹(或斜纹)机织除尘布袋为主。目前已开始逐步使用薄型针刺毡。
The selection principle of dust removal cloth bag of this kind of dust removal equipment is basically the same as that of the chamber back blow type dust remover, with satin (or twill) woven dust removal cloth bag as the main one. At present, thin needle felt has been gradually used.
4、喷嘴反吹类粉尘除尘设备
4. Nozzle back blowing dust removal equipment
回转反吹粉尘除尘设备和往复反吹粉尘除尘设备主要采用带除尘框架的外滤扁袋形式,结构紧凑,此类粉尘除尘设备要求选用比较柔软,结构稳定,耐磨性好的除尘布袋,优先用中等厚度针刺毡除尘布袋,单位面积质量为350~500g/m2。
Rotary back blowing dust removal equipment and reciprocating back blowing dust removal equipment mainly adopt the form of outer filter flat bag with dust removal frame, which is compact in structure. Such dust removal equipment requires the selection of relatively soft, stable in structure and good in wear resistance. Medium thickness needled felt dust removal bag is preferred, with unit area mass of 350-500g / m2.
粉尘除尘设备是一种应用较广的除尘设备,除尘布袋是其核心部件,除尘布袋的选择对粉尘除尘设备的除尘至关重要。从最初大部分采用国外除尘布袋到逐渐采用国产除尘布袋替代,见证了国内除尘布袋发展的历程。
Dust removal equipment is a kind of widely used dust removal equipment, and dust bag is its core component. The selection of dust bag is very important for dust removal equipment. From the initial use of foreign dust bags to the gradual use of domestic dust bags to replace, witnessed the development of domestic dust bags.
