The Following Requirements Should Be Noted in The Daily Use of Stainless Steel Bag Filters

The structural design of the stainless steel bag filter is to seal the top cover and the filter cartridge with four sets of pendulum-type ring bolts, so that the filter can better withstand extremely high filtration pressure and water hammer-type pressure shocks. The bag filter consists of a filter cartridge, a filter basket, and a filter bag. The structure is compact and simple; the liquid to be filtered enters through the filter inlet, flows into the filter bag, and flows out of the filter outlet after being intercepted by the filter bag. The inlet and outlet design of the bag filter generally adopts the side-in and bottom-out method for easy cleaning.

1. Daily use

The working filtration system needs to frequently check the pressure difference between the inlet and outlet. When the pressure difference reaches 0.05-0.1Mpa, the filter bag should be replaced in time to avoid excessive pressure difference, which may cause the filter bag to rupture and the support net to be damaged.

2. Open the filter cover after filtration correctly

Warning: Do not open the cover when there is pressure in the bag filter, otherwise the remaining liquid may spray out, causing liquid loss and personal injury.

Therefore, please strictly follow the following order:

1. Close the input valve; when there is pressure at the outlet, close the output valve.

2. After confirming that the pipe connected to the exhaust valve has been connected to a safe place or the suction port (especially when filtering toxic and corrosive liquids), open the exhaust valve to prevent the liquid from causing harm and pollution to the staff and the surrounding environment.

3. Check the pressure gauge to make sure that the internal pressure is 0. At this time, the bag filter should be separated from the pipeline system.

4. If there is a drain valve, confirm that the drain liquid is connected to the recovery point and open the drain valve; wait until the remaining liquid in the bag filter flows out through the drain valve, and close the drain valve. This discharge work can be completed in conjunction with the pressurization method (please refer to the pressurized discharge process).

5. Unscrew the upper cover cap, lift the upper cover, and the multi-bag filter needs to be turned to a certain angle.
