烧毁:若使除尘布袋长时间处在烟气超过布袋正常使用温度时,很容易使除尘布袋硬化收缩,或融化产生破洞.布袋初始层的厚度不够

1、布袋除尘器厂家分享烧毁:若使除尘布袋长时间处在烟气超过布袋正常使用温度时,很容易使除尘布袋硬化收缩,或融化产生破洞.布袋初始层的厚度不够,被烟气带入的火星进入布袋、或粉尘发热,同样会使除尘布袋烧出孔洞.除尘布袋烧毁主要体现在更换除尘布袋除上.由于在线更换后未进行预涂灰,高温烟气携带火星直接触布袋,易使除尘布袋受到烧损.防止烧毁措施:确保除尘布袋表面的初始层厚度.

1. Bag dust collector manufacturers share burning: if the dust bag is kept in the flue gas for a long time beyond the normal temperature of the bag, it will easily make the bag harden and shrink, or melt to produce holes. Inadequate thickness of the initial layer of the bag, Mars brought by the flue gas into the bag, or dust heating, will also make the bag burn out holes. The burning of the bag is mainly reflected in replacing the bag to remove dust. As the pre coating is not carried out after the on-line replacement, the high-temperature flue gas carrying Mars directly touches the bag, which is easy to burn the bag. Measures to prevent burning: ensure the initial layer thickness of the bag surface.

2、磨损:磨损除尘布袋主要发生在除尘器中间部位,在单个除尘布袋上主要发生在布袋距出口1米范围内.其主要原因为烟气分布不均,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,也使除尘布袋的织物纤维张力受损,容易局部布 袋穿孔、使用周期过短.针对经常磨损部位的除尘布袋更换成耐磨损的布袋.

2. Wear and tear: Wear and tear cloth bags mainly occur in the middle part of the dust collector, and on the single bag, they mainly occur within 1 meter from the outlet. The main reasons are uneven distribution of flue gas, high velocity of flow in the middle part of the single room and high velocity of filter gas near the outlet of the single bag, which results in dust impact and wear, and also damages the fabric tension of the bag. Local cloth bags are perforated and their service life is too short. Dust removal bags for frequently worn parts are replaced by wear-resistant cloth bags.

3、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.烟气中含尘超过设计标准,也会使布袋加速磨损.小灰斗积灰过多,致使烟气室中烟气含尘过大会加速布袋的磨损.

3. Excessive filtration gas velocity will break the initial dust layer and cause excessive wear and tear when dust impacts the cloth bag. If the frequency of cleaning the cloth bag at this time is too high, it will easily lead to loosening of the fabric and accelerating the wear and tear of the cloth bag. Dust in the smoke exceeds the design standard, it will also accelerate the cloth bag wear and tear. Too much dust accumulates in the small ash hopper will accelerate the cloth bag wear and tear if the smoke in the smoke chamber contains too much dust.

4、除尘布袋间的距离过小、龙骨弯曲等容易造成布袋间的磨损.布袋与龙骨的直径相差关系,太小时清洗效果不好,将造成减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.对某些滤布随温度变化较大、而且有伸长的特性,需特别注意.

4. It is easy to cause wear and tear between bags when the distance between bags is too small and the keel is bent. The difference between the diameter of bags and keel is not good when the cleaning time is too small. It will shorten the cleaning cycle and increase the pressure of air injection. The friction between bags and keel will accelerate wear and tear when it is too large. Special attention should be paid to the characteristics of some filter cloths which vary greatly with temperature and have elongation.

5、龙骨焊接处有破洞或毛刺时,或因腐蚀产生的粗糙的表面,亦会加速布袋的磨损.布袋与多孔板密封不严,会造成布袋顶端反褶处磨损.

5. When there are holes or burrs in the keel weld, or rough surface caused by corrosion, the wear of cloth bags will also be accelerated. Lack of sealing between cloth bags and porous plates will cause the wear of the fold at the top of cloth bags.

6、文氏管或脉冲管相对布袋对齐不正,容易使喷吹管喷出气流直接冲刷布袋上段产生磨损.布袋清洗太频繁,会加速布袋的磨损.http://www.sdxhyhbgc.com/

6. The misalignment of the Venturi tube or pulse tube with the cloth bag can easily cause the jet flow from the nozzle to wash the upper part of the cloth bag directly and cause wear. Too frequent cleaning of the cloth bag will accelerate the wear of the cloth bag. http://www.sdxhyhbgc.com/
