Reasons for clogging of filter bag

Causes of bag failure of biomass boiler dust collector
1. Dust collector clogging Because the amount of ash carried by the flue gas greatly exceeds the design value, a large amount of dust particles are attached to the cloth bag. Cloth bag dust collector is blocked for a long time, which increases the bag end difference, especially when the ash content and humidity are high.
2. When the injection pressure starts the injection, a large pressure is generated in the bag. When the bag of the dust collector is tightly wrapped by ash and the pressure cannot be discharged, it will have repeated impacts on the bag. When the bag cannot withstand the impact Torn.
3. High exhaust temperature The exhaust temperature is 150 ℃ for a long time. This temperature exacerbates the embrittlement effect of the gas on the bag and is also a cause of damage to the bag.
4. Corncob's viscosity Corncob contains a large amount of sugar. At higher temperatures, ash particles with large viscosity adhere to the cloth bag, which is not easy to fall under the action of blowing, which is also the reason for the tearing of the bag. It is also prone to spontaneous combustion and burn the cloth.
5. Inflation air source Bags must use a medical compressed air source for injection. The moisture and ash in the miscellaneous air source are combined to easily stick to the cloth bag.
