The filtration work of the filter is a meticulous thing, and the filtering effect of the filter has a great relationship with the filtering effect and the preparation work before the filtration. The filter plays an extremely important role in many industrial productions. It can effectively remove impurities such as particles or suspended matter in the filter, so that the substances that need to be filtered are purified and cleaned. The following are some of the factors that my company has summarized that affect filter filtration.
The
The first effect of the filter bag is related to the operating conditions. In order to obtain a good filtering effect, a relatively low flow rate is generally selected. The slower the flow rate, the better the interception effect and the clearer the filtration, but it will seriously affect the filtration efficiency and increase the burden on the company. If the flow rate is too fast, the filtration efficiency can be greatly increased in a unit of time, and the output of the enterprise can be increased. However, the excessive flow rate will increase the burden on the filter bag. If the pressure is too high, the filter bag will break easily; the clogging of the filter bag will occur more easily and the life of the filter bag will be shortened. , Increase the frequency of filter bag replacement to make work more frequent replacement bags; At the same time, the larger pressure is easy to make fine impurities out of the fabric of the filter cloth blocking the re-contamination of the filtered liquid. Therefore, before replacing the new equipment, a new filter bag should be used according to the advice of professionals and the appropriate flow rate should be used to maximize the filtration efficiency of the filter and to save costs for the customer.
The
In the filtration process, do not use high-precision filter bags, although the higher the sense of precision, the cleaner the experience of filtering out, but in fact to integrate the size of the impurities inside, you must choose the appropriate accuracy. Practice has proved that the high accuracy of the filter bag can easily lead to plugging of the filter bag. Once the filter bags with different precisions have been replaced, or the original filter bag manufacturers have been replaced, the filtering accuracy of the filter bags will be affected, which will affect the filtering effect.
The
The type of particles in the filtrate also has a certain influence on the filtering effect of the filter. Under normal circumstances, the filter fluid particles can be divided into deformable and non-deformable. Deformable particles in the filtration process will be deformed due to the influence of pressure, resulting in blockage of the filter mesh, thereby affecting the filtering effect.
The
The choice of filter bags is also crucial. Filter bags of the same precision have different product filtration results from different manufacturers. The main reason is that the domestic filter media industry does not have a clear industry norm. Many manufacturers are quoting the indicators of foreign manufacturers. Most of the filter media manufacturers are small-scale enterprises, and their production is affected by the process equipment and funds. The restrictions on the quality of the filter media produced are different. These factors have a great influence on the quality of the filter bags produced by the filter bag manufacturers. Therefore, consumers must pay attention to this issue when purchasing filter bags. The standards vary from one manufacturer to another, and the use of filter bags produced by different manufacturers requires high attention.
