The bag filter can select the corresponding filter elements according to the different filter media, and then meet the needs of the water quality. In order to let everyone know more, Shandong snyli Purification shares the operating principle and advantages of the bag filter
The working principle of the bag filter is that the suspension is pumped into each closed filter chamber of the filter. Under the action of the operating pressure, the bag filter or other filter materials are discharged through the outlet and the filter residue is left in The filter cake is formed in the frame, and then reaches the solid-liquid separation.
In the process of application, the bag filter has many characteristics such as strong corrosion resistance, good temperature resistance, high dirt holding capacity, convenient operation, long service life and large flow rate. It is very popular with its wide range of users. Filtering at work The system needs to check the pressure difference between the inlet and outlet frequently. When the pressure difference reaches 0.05-0.1Mpa, the filter bag should be replaced in time to avoid rupture of the filter bag and damage to the support net.
After the bag filter admits that the pipe connected to the exhaust valve has been connected to its safety or suction port, open the exhaust valve, which can effectively prevent its liquid from polluting the staff and the surrounding environment. As well as damage, it is useful to check the pressure gauge to confirm that the internal pressure is 0. At this moment, the bag filter should have been separated from the pipeline system.
The high efficiency filter bag of the bag filter is made of fine fiber, and the hydrophilicity of these materials is weak. The surface of the fiber will not be wetted by water, so like other filter elements using the same material, it must be wetted with some other liquid with lower surface tension before use. Before installation, you must immerse the filter bag in a pre-wet liquid that matches the filtered liquid for several minutes.
