In the practical use of the bag filter, although the equipment has some characteristics such as good sealability and strong circulation ability, if it is not cleaned for a long time, it will cause its machine to a great extent. Internal pollution occurs.
Although the bag filter has the characteristics of good sealability and strong flowability, if it is not cleaned for a long time, it will cause pollution inside the machine to a great extent. Therefore, we must pay attention to the cleaning and maintenance of bag filters. For cleaning time, under normal circumstances, we can refer to the value of the pressure gauge installed on the inlet and outlet pipes of the bag filter, and determine the time for replacing the filter bag by the pressure difference shown by the front and rear pressure gauges. Generally, the filter bag can The differential pressure is about 0.5-1kg/cm2. When the pressure difference reaches this range, we should replace the filter bag in time to avoid the filter bag breaking and affecting the filtering effect.
For the cleaning steps of the filter bag, first of all, we can stop the original pump and close the inlet and outlet valves. Second, we can open the drain valve and the exhaust valve, empty the filter and store the water; finally, disassemble the filter. Filter bag cleaning. In the cleaning, we only need to put a little cleaning liquid, soak for more than ten minutes, you can clean out the impurities in the filter bag. It should be noted that it is necessary to use warm water for cleaning as much as possible.
If you want to extend the useful life of your bag filter, in addition to regular cleaning, you need to pay attention to its maintenance. We must always check the connection pipe is firm, whether there is leakage and damage; When the filter bag is replaced, if it is a sewn filter bag, it is necessary to pay attention to the folding of the filter bag after the edge of the sewing machine. This can improve the filter effect of the sewn filter bag, place the filter bag, pay attention to the filter bag ring mouth and metal The inner net collar fits in.
We found that the pressure at the outlet of the bag filter, they must be timely closing the outlet valve. If you do not pay attention to this, it will have a rather bad effect. When you open the exhaust valve, you must check whether the pipes of the bag filter have been correctly connected and whether they are connected properly. If you ignore this, then when you filter out some harmful substances, it will cause harm to the relevant staff, and it will also pollute the surrounding environment.
