移动碎石机租赁中布袋除尘器布袋更换因素都有哪些?

  移动碎石机租赁中布袋除尘器布袋频繁更换因素都有哪些,解决措施都有哪些,那么今天就由济南大黄蜂工程机械有限公司带大家了解一下吧!
  In the leasing of mobile crusher, what are the frequent replacement factors of bag filter and bag, and what are the solutions? Today, Jinan Bumblebee Construction Machinery Co., Ltd. will take you to know about it!
  原因一:烧毁
  Cause 1: burning
  主要原因是布袋表面的初始层厚度不够,烟气的温度过高所致。如果除尘器处理的烟气温度一直超过布袋的工作条件,容易使除尘布袋硬化收缩或融化产生破洞。如果初始层厚度不够,烟气中的火星流入、或粉尘发热,也可能使布袋烧出孔洞。
  The main reason is that the thickness of the initial layer on the surface of the bag is not enough and the temperature of the flue gas is too high. If the temperature of the flue gas treated by the precipitator always exceeds the working conditions of the bag, it is easy to make the bag harden, shrink or melt, resulting in holes. If the initial layer thickness is not enough, the sparks in the flue gas flow in, or the dust heats up, the bag may also burn out holes.
  防止烧毁措施:确保除尘器布袋表面的初始层厚度,对薄弱部位进行加厚;保证排烟温度不超温。
  Measures to prevent burning: ensure the initial layer thickness of the bag surface of the dust remover, thicken the weak parts, and ensure that the exhaust gas temperature does not exceed the temperature.

  原因二:磨损
  Cause 2: wear
  主要发生在中间部位,原因是烟气分布不均,在单室中间部位流速过高,在单个除尘布袋上靠出口处的过滤气速过高,致使粉尘冲击、磨损布袋。同时也会导致布袋的织物纤维张力受损,容易局部穿孔,使用周期过短。
  It mainly occurs in the middle part, because the flue gas distribution is uneven, the flow velocity in the middle part of a single room is too high, and the filter gas velocity at the outlet of a single dust bag is too high, which causes dust impact and wear of the bag. At the same time, it will also cause the fabric tension of the bag to be damaged, easy to partial perforation, and short service life.
  减少磨损措施:针对经常磨损部位的除尘布袋,可以更换成更加耐磨的布袋。
  Measures to reduce wear: for the dedusting cloth bag in the frequently worn part, it can be replaced with a more wear-resistant cloth bag.

  原因三:布袋间距过小、龙骨弯曲
  Cause 3: too small space between bags, bent keel
  布袋与龙骨的直径相差关系,太小时清洗效果不佳,将造成剪短清洗周期和提高喷吹空气的压力;太大时布袋与龙骨的摩擦会加速磨损。
  The difference between the diameter of the cloth bag and the keel results in poor cleaning effect when it is too small, which will shorten the cleaning cycle and increase the pressure of air injection; when it is too large, the friction between the cloth bag and the keel will accelerate wear.
  措施:布袋在安装过程中,对距离过小、龙骨弯曲的布袋进行调整更换;除尘布袋与龙骨配合要合适,且长度应该一致;龙骨在使用前应严格检查,破损的龙骨严禁使用。
  Measures: during the installation of the cloth bag, the cloth bag with too small distance and bent keel shall be adjusted and replaced; the dust removal cloth bag and keel shall match properly and have the same length; the keel shall be strictly inspected before use, and the damaged keel is strictly prohibited to use.
  原因四:过滤气速过高
  Reason 4: too high filtration gas speed
  过高的过滤气速,会使初始粉尘层破碎,以及粉尘冲击布袋而造成过度磨损。如果此时清洗布袋次数过高极易导致布袋的织物松散,加速布袋的磨损。
  Too high filtration gas velocity will make the initial dust layer broken, and the dust will impact the bag and cause excessive wear. If the cleaning times are too high at this time, it is easy to cause the fabric loose and accelerate the wear of the bag.
  措施:在运行过程中,防止过滤速度过高、布袋的清洗周期过短。
  Measures: in the process of operation, prevent the filter speed from being too high and the cleaning cycle of the cloth bag from being too short.
