For some of the performance aspects of multi bag filters, they may not be particularly outstanding, but the ability to use multiple filter bags is even more important in showcasing their multi filtration advantages, allowing for more comprehensive filtration work.
By modifying old-fashioned products, the multi bag filter will become more convenient for users to operate. Multi bag filters have been widely used in various aquaculture industries, and in the coal industry, bag filters with high flow rates such as "straight through" bag filters are widely used.
Fully automatic filter, filter, fully integrated water processor, electronic descaling device, backwash filter with high filtration accuracy: The fully automatic bag filter backwash filter has two or more sets of filter elements inside, with a large flow area and small original pressure loss, which can achieve high flow and high-precision filtration, which is difficult to achieve with traditional filters.
Users who have chosen multi bag filters are aware that they may encounter some problems during daily operation. Now, let's introduce the methods for handling them:
1. The installation of filter machines in series can achieve step-by-step filtration. If installed at the front end of a filter used for high-precision filtration, it can significantly reduce filtration costs. Similarly, sand filtration and other filtration methods can be combined with bag filtration to further improve filtration quality and reduce the consumption cost of filter bags. By combining self-cleaning machines, centrifugal and bag filters, we can use them separately or in series with other principle filters to achieve the desired effect.
2. When to replace the filter bag of a multi bag filter? In practical applications, there are two ways to determine when to replace the filter bag: to roughly determine the replacement time based solely on experience.
Pressure gauges are installed on the inlet and outlet pipes of the bag filter machine, and the time to replace the filter bag is determined by the pressure difference displayed on the front and rear pressure gauges. Generally, the filter bag can withstand a pressure difference of about 0.5-1kg/cm2. When the pressure difference reaches this range, the filter bag should be replaced in a timely manner to avoid bag rupture and affect the filtration effect. Do not sacrifice the big for the small.
3. The more impurities there are, the more frequent the replacement of filter bags, and the longer the standby time, the more unfavorable it is for production. Therefore, in system design, it is necessary to increase the filtering area appropriately.
4. If the interception medium is hard, surface filtration such as metal mesh, nylon mesh, etc. should be selected. If it is soft or colloidal particles, deep filtration should be selected.
5. Pay attention to the working conditions of the filter medium, such as chemical compatibility, flow rate, and temperature, to determine the type of filter: single bag or multiple bags, which grade of stainless steel (such as 304, 316L, etc.) is used for the filter material, and the sealing material.
