          家具厂除尘设备的操作注意事项
          Operation precautions of dust removal equipment in furniture factory
          家具厂除尘设备的操作注意事项:一般在干净织物使用后的头几个过滤周期内,清灰所除去的沉积粉尘比较多,以后越来越少。经过一段时间,清灰后的剩余粉尘便达到大致是恒定的数值。
          Precautions for operation of dust removal equipment in furniture factory: generally, in the first few filter cycles after the use of clean fabrics, the deposited dust removed by dust removal is more and less, and less and less in the future. After a period of time, the residual dust after dust removal will reach approximately constant value.
          1,电能消耗大,不经济。
          1. The power consumption is large and uneconomical.
          2,阻力超过了通风系统设计所取的大数值,通风不能满足需要。
          2. The resistance exceeds the large value of the ventilation system design, so the ventilation can not meet the needs.
          3,粉尘堆积在滤袋上后,孔隙变小,空气通过的速度就要增加。当增加到一定程度时,会使粉尘层产生“针孔”,以致大量空气从阻力小的针孔中流过,形成所谓“漏气”现象,影响除尘效果。
          3. After the dust accumulates on the filter bag, the pore becomes smaller and the air passing speed will increase. When it is increased to a certain extent, the "pinhole" will be produced in the dust layer, so that a large amount of air will flow through the pinhole with small resistance, forming the so-called "air leakage" phenomenon, affecting the dust removal effect.
          4,阻力太大,滤料容易损坏。因此,袋式除尘器在使用过程中都要通过某种方尘清除滤袋上累积的粉尘(即使单从收集粉尘的角度来说,也要把滤袋上捕集的粉尘除下来,才能收集)。不过,一般在清灰以后还有相当多的粉尘残留在织物的孔隙内,清灰后的剩余阻力和时间以及从损伤织物的角度来看,这样做是不经济的,而且在清灰后,下一个过滤器周期开始时,剩余粉尘还可以起相当大的捕尘作用,所以清灰不需要彻底。
          4. The resistance is too large, and the filter material is easy to be damaged. Therefore, in the process of using the bag filter, the dust accumulated on the filter bag must be removed by some kind of square dust (even from the perspective of dust collection, the dust collected on the filter bag must be removed before collection). However, in general, there are still quite a lot of dust left in the pores of the fabric after ash removal. From the perspective of residual resistance and time after ash removal and damage to the fabric, it is uneconomical to do so. Moreover, after ash removal, at the beginning of the next filter cycle, the residual dust can also play a considerable role in dust collection, so ash removal does not need to be thorough.
