技术:环保除尘设备除尘布袋容尘量与过滤效率的关系

文章发布: 发表时间: 2017-03-21 10:04:13

除尘布袋容尘量又称粉尘负荷指到达给定阻力值时单位面积滤料上积存的粉尘量。除尘布袋的容尘量影响滤料阻力的巨细和清灰周期的长短。为了防止环保除尘设备的频频地清灰,延伸滤袋寿数,通常请求除尘布袋的容尘量要大些。除尘布袋的容尘量与滤料的孔隙率,透气率有关,毛毡滤料比织物滤料的容尘量大。
Dust bag dust also known as dust load refers to reach a given resistance value of the unit area of the amount of dust stored on the media. The dust holding capacity of the dust collecting bag affects the size of the filter resistance and the length of the cleaning cycle. In order to prevent the removal of environmental protection equipment frequently cleaning, extended his bag, usually request dust bag dust holding capacity larger. The dust content of the dust bag is related to the porosity and permeability of the filter material, and the dust content of the felt filter material is larger than that of the fabric filter material.
滤料的过滤功率一方面与滤料构造有关,另一方面也取决于滤料上所形成的粉尘层,从滤料构造看,短纤维的过滤效果比长纤维高。毛毡滤料比织物滤料高。从粉尘层的形成来看,关于薄滤料,清灰后,粉尘层被损坏,功率下降许多,而厚滤料,清灰后还可保存一部分粉尘在滤猜中,防止过度清灰。通常来说,在滤料不决裂的情况下,均可到达最高的效率。所以,只需规划参数选择妥当,环保除尘设备的除尘效果应无问题。
On the one hand, the filter power is related to the structure of the filter material, on the other hand, it also depends on the formation of the dust layer on the filter material, from the filter structure, the short fiber filtration effect is higher than the long fiber. Felt material is higher than fabric filter. From the formation of dust layer, a thin filter, after cleaning, the dust layer is damaged, power down many, thick dust filter, also can save a part of the dust filter in the right, to prevent excessive dust. Generally speaking, in the case of the filter material does not break, can achieve the highest efficiency. Therefore, only the appropriate choice of planning parameters, environmental protection dust removal equipment should be no problem.
怎么收购优异除尘布袋
How to acquire excellent dust bag
收购好的除尘布袋具体来说,为了满意公司生产的需求,除尘布袋应当契合以下的请求:
The acquisition of a good dust bag specifically, in order to meet the needs of the company's production, dust bag should meet the following requirements:
1、有杰出的透气性,环保除尘设备的功用,即是用来去掉粉尘的,所以滤料的容尘量,有必要足够大。如今商场上有一些质量对比差的除尘布袋,每敞开一起清灰功用,就会“缩水”一次,这即是不合格的商品。
1, has the good permeability, environmental protection dust removal equipment function, that is used to remove dust, so the amount of dust filter material, it is necessary to large enough. Today, there are a number of poor quality shopping on the dust bag, each with a clear ash function, it will shrink once, which is not qualified goods.
2、抗温、抗腐蚀性较强。相信大多数公司都知道,除尘布袋假如不能有良好的抗温和抗腐蚀性,很快就会被损坏,丧失除尘的功能,影响到环保除尘设备的正常运用。
2, temperature resistance, corrosion resistance. I believe that most companies know that if the dust bag can not have a good anti - corrosion resistance, will soon be damaged, the loss of dust removal function, affecting the normal use of environmental protection dust removal equipment.
3、易于清灰。清灰质量的好坏,和除尘布袋自身的质量,也有必定的联系。比如长纤维和短纤维两者原料,短纤维的原料,虽然有非常好的滤尘性,但要清理上面的粉尘,就显得比较艰难。
3, easy ash cleaning. The quality of the ash removal is good or bad, and the quality of the dust bag itself has certain connection. For example, long fiber and short fiber raw materials, the raw material of short fiber, although there is a very good filter dust, but to clean up the dust above, it becomes more difficult.
