How to do the maintenance of the microporous filter to extend the service life
Microporous filter is a new type of filtering equipment, which can filter out particles and bacteria above 0.1um of liquid and gas. It has high filtration precision, fast transition speed, less adsorption, no media shedding, acid and alkali corrosion resistance, and operation. Convenience and other advantages. It is now widely used in industries such as water treatment.
According to the principle of the micropore filter, it is completely a mechanical separation technology. After the liquid (or gas) is passed through the filter element (or the filter membrane) by pressure, the impurities of the large particles in the medium are trapped by the micropores to achieve the purification effect. .
The industry said that microfiltration has an advantage at this point, but one drawback of microfiltration is that it can hardly be regenerated. After the filter life is reached, it cannot be cleaned or repaired. It must be replaced once it is used up. Filtration can only remove granulated magazines, and it is impossible to remove ions or separate molecules with different molecular weights. Therefore, microfiltration can only be applied in filtration without strict changes in raw materials.
Many users are concerned about the longevity of their choice when using or using a microfiltration filter. In fact, in addition to the quality, operation and other factors, the life of the equipment is closely related to its usual maintenance work. Regular maintenance of the micro-filter can not only improve the filtration accuracy, but also prolong the service life of the micro-filter. So, how should the user do the maintenance of the microporous filter?
“Microporous filters must look at what type of filter before maintenance. Different types require different maintenance methods.” According to the industry, there are two types of microporous filters, one is precision microfiltration. The other is a coarse filter microporous filter.
For precision microporous filters, care should be taken when performing maintenance. Since the core of the precision microporous filter is a filter element, and the filter element is made of a special material, it is a suitable part and therefore requires special protection.
When the precision microporous filter works for a period of time, the filter cartridge blocks a certain amount of impurities. At this time, the pressure drop increases, the flow rate decreases, and the impurities in the filter need to be removed in time, and the filter element is cleaned at the same time.
When removing impurities, pay special attention to the precision filter element, and it must not be deformed or damaged. Otherwise, the filter element installed again will not meet the design requirements after filtration. If the filter element is found to be deformed or damaged, it needs to be replaced immediately.
In addition, some precision filter elements can not be used repeatedly, such as bag filter, polypropylene filter and so on.
For the coarse filter, the core part of the coarse filter microfilter is the filter core, the filter core is composed of the filter frame and the stainless steel wire mesh, and the stainless steel wire mesh is a suitable piece, which needs special protection.
The industry said that, like the precision filter, when the filter of the coarse filter works for a period of time, certain impurities are precipitated in the filter core. At this time, the pressure drop increases, the flow rate decreases, and the impurities in the filter core need to be removed in time. .
When cleaning impurities, pay special attention to the stainless steel wire mesh on the filter core can not be deformed or damaged. Otherwise, the filter will be installed again. The purity of the filtered media will not meet the design requirements, and the compressor, pump, instrument and other equipment will be destroyed. .
