To reduce the bag filter corrosion

1, reduce the gas moisture content

Reducing the moisture content of the gas reduces the dew point temperature of the gas, and also increases the temperature of the gas as much as possible, so that the temperature difference between the gas temperature and the dew point temperature increases. Practice has also proved that this empirical value is small, because many working conditions are difficult to predict, if the air leakage rate is relatively large, the gas temperature is better than the dew point temperature of 30 degrees or more.

2, reduce the bag leakage rate

Leakage is also an important cause of the corrosion of the dust collector, because the air leakage is closely related to the negative pressure inside the dust collector. The greater the negative pressure, the more serious the air leakage will be; while the positive pressure operation will not adversely affect the performance of the dust collector. , but dust is relatively easy to enter inside the dust bag, so be sure to improve his sealing structure. This will not be so obvious fan wear.

3, strengthen the system's seal

This method mainly includes the seal of the dust collector itself and other equipment and pipes in the dust collector system. Because the density of the dust collector itself depends on the housing, in order to maintain good sealing of the housing, it is first necessary to ensure the quality of manufacture and installation. Moreover, continuous welding is preferably used for all joints of the housing, and heat-resistant silicone rubber is also used for sealing around the door.
