When the bag filter is used, the structure of the filter device is reasonable and the operation is simple and flexible. The utility model has the advantages of energy saving, high efficiency, wide application range, strong adaptability and the like, and the multi-purpose filtering device is effective when used. Its fine polishing, high-pressure shot peening polishing process, so that the inner and outer walls are smoother, easier to clean, less filter residue, replacement of the filter bag is very convenient.
The bag filter is capable of filtering the liquid to a certain extent, and can also be applied to food, sanitation, and pharmaceutical industries, and is also capable of performing in a harsh corrosive harsh application environment. Bag filter stainless steel shell, the appearance of a mirror treatment, good-looking and small footprint; at the same time according to the customer’s chemical properties of the material in the stainless steel barrel to do acid and alkali, resistant to organic solvents; internal stainless steel mesh, Acid and alkali resistant, solvent-resistant filter bag, bag filter change filter bag is very convenient.
In the condition that the liquid input pressure is stable, the bag filter is closely related to the filter quality inside and outside the filter bag. If the pressure difference is too large during use, it will directly indicate that the filter hole of the filter bag has appeared. As a result of the clogging, the filtration rate decreases. Therefore, it is recommended that when the bag filter starts to work, the pressure difference should be checked regularly, and the time for replacing the filter bag is determined by the pressure difference shown by the front and rear pressure gauges. Generally, the pressure difference that the filter bag can withstand is 0.5 to 1 kg/. About cm2, when the pressure difference reaches this range, the filter bag should be replaced in time to avoid the filter bag from breaking, affecting the filtering effect.
If the pressure difference suddenly drops in the bag filter, stop the filtration immediately and check for leaks. The bag filter can operate normally under certain pressure during the process of production, to a certain extent, ensuring that the outlet pressure meets the processing requirements of the water quality, and the purified water of the bag filter can be directly sent to the high water tower. To the extent that the secondary water pumps and supporting facilities required for general water supply projects are saved, investment and operating costs are saved.
