What hazards will occur when the temperature of the filter cartridge dust collector is deviated?

The operating temperature of the filter cartridge dust collector is an important basis for the design. When the operating temperature deviates from the design temperature, the filter cartridge dust collector will not work properly. Therefore, if the dust with high temperature, it needs to be cleaned before entering the dust collector. Cooling work, otherwise it will cause the resistance of the device to increase sharply, so that it will not work properly.

During the dust removal process of the filter cartridge dust collector, water vapor will enter the dust removal filter cartridge with the exhaust gas. If the temperature is too low, the filter cartridge will be damp and then freeze, resulting in the filter cartridge dust collector unable to play its original role and reducing the dust removal efficiency. If this phenomenon is not properly handled in time, the corrosion of the filter cartridge dust collector will be aggravated and the service life of the dust collector will be shortened.

In severe cases, the dust will even stick to the surface of the filter cartridge, blocking the pores of the filter bag, resulting in a sudden increase in resistance, which makes it unable to work normally. Therefore, it is particularly important to keep the filter cartridge dust collector warm in winter.

When the exhaust temperature of the filter cartridge dust collector exceeds 160 °C, the temperature has a significant impact on the life of the filter cartridge. As the temperature increases, the life of the filter cartridge will gradually increase, and the filter cartridge will be burned when the corresponding temperature is reached. For high temperature gas, cool it to below the temperature that the filter material can withstand, generally it should be controlled below 120 °C.

There are various cooling methods, the more typical ones are natural air duct cooling, forced air cooling, water cooling, etc., which can be designed and selected according to different processes, cooling temperature, layout size requirements, etc.

For high temperature flue gas dust removal, the filter cartridge dust collector should control the excessive temperature of the flue gas to prevent the filter cartridge from burning, and control the too low temperature to prevent the flue gas from condensing and corroding on the dust removal filter cartridge, as long as the temperature resistance conditions of the filter cartridge allow , the flue gas temperature should be made as high as possible, so that the inside of the dust collector can be kept dry and the ash cleaning can be carried out normally, so as to create good operating conditions.
