  • 袋式空气过滤器滤袋堵塞怎么办?
    来源: 浏览:次 发布日期:2019-06-19
      袋式空气过滤器是一种结构新颖、体积小、操作easy灵活、节能高效、密闭work、适用性强的多用途过滤空气净化设备。袋式过滤器是一种新型的过滤系统。滤袋由滤袋内的金属网篮支承,空气通过入口进入。通过滤袋过滤下,从出水口流出。杂质被截留在滤袋里。
      Bag air filter is a multi-purpose air purification equipment with novel structure, small volume, simple and flexible operation, energy saving, high efficiency, closed operation and strong applicability. Bag filter is a new type of filtration system. The filter bag is supported by a metal mesh basket in the filter bag, and air enters through the inlet. After being filtered through a filter bag, it flows out of the outlet. Impurities are trapped in the filter bag.
      袋式空气过滤器滤袋堵塞的主要原因是过滤速度快、粉尘细、粘尘、粉尘清洗差、糊袋、凝结、硬化。当除尘器的过滤风速超过滤袋的策划准则时,烟气中的细粉尘很匆子 侄媒肼舜南宋校黾勇舜淖枞枇ΑT诼舜砻嫱磕す酥柿稀⑼磕す酥柿匣蛟ね磕な且恢纸虾玫姆椒ā6杂诟哒扯鹊姆鄢荆枰档凸怂俣龋蛟黾勇龀迮缌苎沽Γ虿扇∮τ美胂呗龀迩寤衣舜5牵玫姆椒ㄊ窃黾庸嗣婊档凸怂俣龋映ぢ舜氖褂檬倜
      The main reasons for the blockage of filter bags in bag air filters are fast filtering speed, fine dust, sticky dust, poor dust cleaning, bag pasting, coagulation and hardening. When the filter air speed of the filter exceeds the design standard of the filter bag, the fine dust in the flue gas can easily enter the fiber of the filter bag and increase the blocking resistance of the filter bag. It is a better method to coat the filter material, the filter material or the pre-coated film on the surface of the filter bag. For high viscous dust, it is necessary to reduce the filtering speed, or increase the pulse spraying pressure, or use off-line pulse ash cleaning filter bag. However, the better way is to increase the filtering area, reduce the filtering speed and prolong the service life of the filter bag.

      The main manifestations of bad cleaning of filter bags are more cleaning times and longer cleaning time. Too many times of cleaning and too much pressure of cleaning can easily loosen the fibrous tissue of the filter bag, increase the fine dust in the flue gas and block the filter bag. If the cleaning time is too long, the initial powder layer on the surface of the filter bag will be washed out, which will result in the decrease of the filtering accuracy of the filter bag. If the cleaning time is too short and the dust on the surface of the filter bag is not completely cleaned, then start the filter. Dust gradually accumulated on the surface of the filter bag, resulting in blockage of the filter bag. In order to solve this problem, the spray controller can be adjusted after several trial runs.
      水是遭成滤袋堵塞的一大原因,水的原因一贯是低温凝结,尤其是在处理 摄氏烟气时,要用这种环境来预防:避免不当开机;电阻大时,避免启动除尘器;打开露点以下。如果除尘器运行在露点以下,很匆子 侄贸鱿中ase。如果进气分布不均匀,匆子 侄靡鸺酒骺翘宓木植扛础R子 ,应避免除尘器work在露点以下。如果不可避免地要在低温下启动,请使用绝缘装置,如蒸汽绝缘或电加热绝缘。
      Water is a major cause of filter bag clogging, water is usually caused by low temperature condensation, especially in the treatment of high-temperature flue gas, to prevent this situation: to avoid inappropriate start-up; high resistance, to avoid starting the dust collector; open below dew point. If the dust collector operates below dew point, it is easy to cause problems. If the intake air distribution is not uniform, it is easy to cause local corrosion of the dust collector shell. Therefore, it should be avoided that the dust collector works below dew point. If it is inevitable to start at low temperature, please use insulation devices, such as steam insulation or electric heating insulation.
      空气渗漏。空气渗透一贯发生在除尘器的法兰,检修门或集尘器的移动设备,如果密封不严格,外部空气进入除尘器,在处理 摄氏烟气时,它将在除尘器内部生产低温区,导致低温冷凝,腐蚀除尘器,导致粘贴袋滤袋或董事会。
      Air leakage. Air infiltration usually occurs in the flange of the dust collector, the overhaul door or the mobile device of the dust collector. If the seal is not strict, the external air enters the dust collector. When dealing with the high-temperature flue gas, it will produce a low-temperature zone inside the dust collector, resulting in low-temperature condensation, corrosion of the dust collector, resulting in sticking bag filter bags or board of directors.
