Bag filter When working, the side leakage rate of the filter bag is small, which can effectively ensure the filtering quality, the device can withstand greater working pressure, the pressure loss is small, the operating cost is low, the energy consumption is low, and the energy saving effect is obvious. The filter accuracy of the filter bag has been continuously improved, reaching 0.5μm.

Compared with other types of filtration equipment, the bag filter has a large processing capacity, a small volume and a large amount of dirt. According to the working principle and structure of the bag filter system, it is convenient and quick to replace the filter bag, and the filter is free of cleaning, which saves time and effort. The filter bag can be reused after cleaning to save costs. Bag filters have a wide range of applications, flexible uses and multiple installation methods.

The filter system at work should always check the pressure difference between the inlet and the outlet. When the pressure difference reaches 0.05-0.1Mpa, the filter bag should be replaced in time to avoid excessive pressure difference, the filter bag ruptures, and the support net is damaged. Open the filter top cover correctly. Be careful not to open the top cover under the pressure of the bag filter, otherwise the remaining liquid may be spit out, causing liquid loss and personal injury.

When operating, please close the input valve first; when there is pressure at the outlet, close the output valve. After confirming that the pipe connected to the exhaust valve has been connected to the safety or suction port, open the exhaust valve to prevent the liquid from causing harm and pollution to workers and the surrounding environment.

Check the pressure gauge to make sure that the internal pressure is zero and the bag filter should be separated from the piping system. If there is a drain valve, make sure that the drain liquid is connected to the recovery point and open the drain valve; the remaining liquid in the bag filter is drained through the drain valve, and the drain valve is closed. The discharge work can be performed in a pressurized manner. Release the top cover, and then lift the top cover. Multi-bag filters need to be rotated at a certain angle.
