花板的鋼板厚度一般為4-6mm ,主要取決于過濾室內懸掛除塵器濾袋的數量,為增加花板的剛度,花板上應增設加強筋。花板外觀應該平整、光潔,不應有翹曲或者凹凸不平等瑕疵,其平面度偏差不大于花板長度的2/1000,花板孔的價格應采用沖孔或者采用等離子切割,不允許采用氣割,用彈性脹圈固定濾袋花板孔徑D的公差為正負1mm?;ò宄?,所以脈沖除塵器制度尺寸之機。
The thickness of the steel plate for the flower board is generally 4-6 mm, mainly depending on the number of dust collector filter bags suspended in the filter room. To increase the stiffness of the flower board, reinforcement ribs should be added on the flower board. The appearance of the flower board should be flat and smooth, without any warping or uneven defects. Its flatness deviation should not exceed 2/1000 of the length of the flower board. The price of the flower board hole should be punched or plasma cut, and gas cutting is not allowed. The tolerance of the hole diameter D of the filter bag flower board fixed with an elastic expansion ring is plus or minus 1mm. The flower board ruler is the machine for measuring the size of pulse dust collectors.
花板上的圓孔以定濾袋,孔之中間去過小,必時除塵器內之版風速(即常言之灌口風速)高,阻力增,清時難粉塵沉灰;或有可使除塵濾袋向齷齪,短濾袋之用命,故須理而定濾袋中間去尺寸。
The circular holes on the flower board are used to fix the filter bag, and the middle of the holes is too small. When the plate wind speed (commonly known as the inlet wind speed) inside the dust collector is high, the resistance increases, and it is difficult for dust to settle during cleaning; Perhaps it can make the dust removal filter bag dirty or short, so it is necessary to adjust the size of the filter bag in the middle.
導致單機布袋除塵器工作效果差的原因有很多,比如清灰系統沒有設計好,使用時未按操作規程等等,這其中的任何一個細節,都可能造成單機布袋除塵器的除塵效果變差。所以企業在單機布袋除塵器采購以及使用的時候,要注意。
There are many reasons that can lead to poor performance of single machine bag filters, such as poorly designed dust removal systems and failure to follow operating procedures during use. Any of these details may cause a decrease in the dust removal efficiency of single machine bag filters. So when enterprises purchase and use single machine bag filters, they should pay attention.
單機布袋除塵器解決潮濕的注意事項:
Precautions for single machine bag dust collector to solve dampness:
1、慎用除塵布袋:應選用不易粘糊的光面除塵布袋,如光面滌綸濾料729、針/刺氈除塵布袋等等;
1. Be cautious when using dust removal bags: choose non stick smooth dust removal bags, such as smooth polyester filter material 729, needle/felt dust removal bags, etc;
2、較短的清灰周期:清灰周期短,有利于及時去除布袋表面石灰粉塵,減少粘結可能;
2. Short cleaning cycle: The cleaning cycle is short, which is conducive to timely removal of lime dust on the surface of the cloth bag, reducing the possibility of adhesion;
3、石灰粉布袋除塵器設置安全旁路管道:當空氣相對溫度升高的時候,進入除塵系統的含塵空氣很易結露,為避免水氣進入單機布袋除塵器粘結濾料,應設置安/全旁路,此時可避免袋式除塵器,讓含塵空氣只通過旋風除塵器,然后排入大氣,以上可采用自動控制;
3. A safety bypass pipeline should be set up for the lime powder bag filter: When the relative temperature of the air rises, the dusty air entering the dust removal system is prone to condensation. To prevent water vapor from entering the bonded filter material of the single machine bag filter, a safety/full bypass should be set up. At this time, the bag filter can be avoided, allowing the dusty air to only pass through the cyclone dust collector and then be discharged into the atmosphere. The above can be controlled automatically;
4、較低的過濾風速:過濾風速較高,將迫使微細石灰粉進入內曲折微孔中發生堵塞,反吹清灰不利時候,長期停留于布袋內部而形成粘接物堵塞濾孔,而采用低過濾風速,可避免上述弊病;
4. Lower filtration wind speed: When the filtration wind speed is higher, it will force fine lime powder to enter the internal winding micropores and cause blockage. When reverse blowing is not conducive to cleaning, it will stay inside the bag for a long time and form adhesive to block the filter holes. However, using a low filtration wind speed can avoid the above drawbacks;
5、足夠的清灰反吹能力:用反吹風清灰,可將進入濾料中的石灰風塵清洗出來,而足夠的壓力,有利于較清洗濾料中的粉塵。
5. Sufficient cleaning and backwashing ability: By using backwashing air to clean the ash, the lime dust entering the filter material can be cleaned out, and sufficient pressure is conducive to cleaning the dust in the filter material.
