The structural design of the bag filter is mainly to seal the top cover and the filter cartridge by four sets of rocker ring bolts, which will make the filter more able to withstand extremely high filtration pressure and water hammer pressure when used. Impact, bag filter consists of filter cartridge, filter basket, filter bag in three parts, the structure is compact and simple; the liquid to be filtered enters through the filter’s inlet, flows into the filter bag, and is intercepted by the filter bag, after the filter’s Outflow.
The design of the bag filter inlet and outlet generally adopts the side-in and bottom-out mode. The cleaning of the whole device is very convenient. It is simple and quick to replace the filter bag. The first step is to close the inlet valve and open the exhaust valve. Valve, let the pressure inside the filter drop to normal pressure.
The bag filter needs to open the four sets of head bolts on the top cover, open the top cover, open the retaining ring fixing the filter bag, put forward the plugged filter bag, put on a new filter bag, close the top cover, and lock the four rings First bolt; fifth step, open the inlet valve, and close the exhaust valve when the exhaust valve has liquid flowing out. The total process is usually completed in about 10-15 minutes.
The bag filter is generally when the pressure difference of the filter reaches 2-3 kilograms, it proves that the filter bag has been basically blocked, and at this time, the outlet of the filter is also very little. Therefore, the filter bag should be replaced at this time. Depending on the conditions of use, if the process requires maintaining the flow rate of the filter not lower than half of the maximum flow rate, the filter bag should be replaced when the differential pressure reaches about 1 kg. The service life of the filter bag is determined by the turbidity of the raw water, the filtration time, the filtered flow rate, and the filter area of the filter bag.
During the operation of the bag filter, it is first necessary to confirm whether the accessories required for installing the bag filter system have been prepared. Check the Ο-type seal ring and the Ο-type groove on the filter. Replace the new accessories. Place the bag filter on the station to be filtered and fix it after connecting the inlet and outlet flanges or the tube teeth; suffocate the exhaust port or configure the exhaust valve.
