Causes of Black Smoke from Boiler Bag Dust Collector


Black smoke emission analysis of boiler bag filter : The tightness of the bypass valve is very important for the bag filter of the bypass device of the boiler bag filter. As long as there is a slight leak, the dust concentration in the exhaust gas may exceed the standard.


The solution should be to use a bypass valve with sealing performance. If necessary, a bypass valve with a double-layer valve plate and air-tight device should be used. The bypass valve should be dustproof. If the valve is not closed tightly due to a fault, it should be repaired in time.


The cloth bag damage of the boiler dust collector is caused by mechanical damage, aerodynamic damage, thermal damage or polymer fiber cracking. The deformation of the flower plate causes the filter bag to tilt, and the bottom of the dust bag is uneven. Under the action of mechanical vibration and air flow The bottom of the filter bag collided, causing holes and cracks in the filter bag near the entrance of the dust collector, causing mechanical damage. The filter bag did not cooperate well with the frame. During the dust removal process, the expansion and contraction of the filter bag would contact the skeleton, thereby aggravating the damage. degree.

Analysis of the cause of black smoke emission from the boiler bag dust collector The aerodynamic damage of the bag of the dust collector is mainly due to the dust accumulation in the clean room caused by the erosion of the high-speed dust-containing airflow at the inlet of the dust collector or the damage of the filter bag. The movement scours the filter bag, increasing the damage of the filter bag.


In addition, the inlet of the vacuum cleaner is also provided with a deflector to disperse and guide the airflow to prevent high-speed dust-laden airflow from directly washing the bag of the cleaner. However, it was found that the improper design and installation of the deflector not only failed to guide and disperse properly. The effect of air flow, and can reduce the dust scouring of the bag. In addition, it will be flushed to produce holes, forming a local high-speed dust air flow, and causing new flushing points to accelerate the damage of the bag. When the rotary pulse dust cleaning device appears When the fault occurs, the observation well cannot see the condition of the rotating arm. When the rotating arm stops rotating, it is not detected in time. Therefore, continuous blowing at one position for a long time, and other filter bags are not cleaned, resulting in increased resistance instead of falling. Due to continuous blowing in a place for a long time, some filter bags were damaged. Field observation of a large number of damaged filter bags showed that the damaged parts of the boiler dust filter bag were almost all round holes and strip-shaped cracks. The test also showed that the damaged The undamaged part of the dust collector bag and other filter bags in the filter unit were not significantly deformed, and the remaining strength was basically normal. This indicates that no significant cracking of the polymer fiber filter material occurred during use.
