        家具廠除塵設備的操作注意事項
        Operation precautions of dust removal equipment in furniture factory
        家具廠除塵設備的操作注意事項:一般在干凈織物使用后的頭幾個過濾周期內,清灰所除去的沉積粉塵比較多,以后越來越少。經過一段時間,清灰后的剩余粉塵便達到大致是恒定的數值。
        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,電能消耗大,不經濟。
        1. The power consumption is large and uneconomical.
        2,阻力超過了通風系統設計所取的大數值,通風不能滿足需要。
        2. The resistance exceeds the large value of the ventilation system design, so the ventilation can not meet the needs.
        3,粉塵堆積在濾袋上后,孔隙變小,空氣通過的速度就要增加。當增加到一定程度時,會使粉塵層產生“針孔”,以致大量空氣從阻力小的針孔中流過,形成所謂“漏氣”現象,影響除塵效果。
        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,濾料容易損壞。因此,袋式除塵器在使用過程中都要通過某種方塵清除濾袋上累積的粉塵(即使單從收集粉塵的角度來說,也要把濾袋上捕集的粉塵除下來,才能收集)。不過,一般在清灰以后還有相當多的粉塵殘留在織物的孔隙內,清灰后的剩余阻力和時間以及從損傷織物的角度來看,這樣做是不經濟的,而且在清灰后,下一個過濾器周期開始時,剩余粉塵還可以起相當大的捕塵作用,所以清灰不需要徹底。
        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.
