单机布袋除尘器的花板的承重问题介绍

花板的钢板厚度一般为4-6mm ,主要取决于过滤室内悬挂除尘器滤袋的数量,为增加花板的刚度,花板上应增设加强筋。花板外观应该平整、光洁,不应有翘曲或者凹凸不平等瑕疵,其平面度偏差不大于花板长度的2/1000,花板孔的应采用冲孔或者采用等离子切割,不允许采用气割,用弹性胀圈固定滤袋花板孔径D的公差为正负1mm。花板尺,所以脉冲除尘器制度尺寸之机。

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.

花板上的圆孔以定滤袋,孔之中间去过小,必时除尘器内之版风速(即常言之灌口风速)高,阻力增,清时难粉尘沉灰;或有可使除尘滤袋向龌龊,短滤袋之用命,故须理而定滤袋中间去尺寸。

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.

导致单机布袋除尘器工作效果差的原因有很多,比如清灰系统没有设计好,使用时未按操作规程等等,这其中的任何一个细节,都可能造成单机布袋除尘器的除尘效果变差。所以企业在单机布袋除尘器采购以及使用的时候,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.

单机布袋除尘器潮湿的注意事项:

Precautions for single machine bag dust collector to solve dampness:

1、慎用除尘布袋:应选用不易粘糊的光面除尘布袋,如光面涤纶滤料729、针/刺毡除尘布袋等等;

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、较短的清灰周期:清灰周期短,有利于及时去除布袋表面石灰粉尘,减少粘结可能;

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、石灰粉布袋除尘器设置旁路管道:当空气相对温度升高的时候,进入除尘系统的含尘空气很易结露,为避免水气进入单机布袋除尘器粘结滤料,应设置安/全旁路,此时可避免袋式除尘器,让含尘空气只通过旋风除尘器,然后排入大气,以上可采用自动控制;

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、较低的过滤风速:过滤风速较高,将迫使微细石灰粉进入内曲折微孔中发生堵塞,反吹清灰不利时候,长期停留于布袋内部而形成粘接物堵塞滤孔,而采用低过滤风速,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、足够的清灰反吹能力:用反吹风清灰,可将进入滤料中的石灰风尘清洗出来,而足够的压力,有利于较清洗滤料中的粉尘。

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.
