In general, a high efficiency filter (HEPA) is a filter having a collection efficiency of 99.97% or more for particles having a particle diameter of 0.3 μm or more. Now widely used in various industries.
There is a partition in it.high efficiency filterBecause it is folded by special folding equipment, special glass fiber paper must be used as filter material or special aluminum foil or paper spacer, which can provide three structures: gasket type, liquid tank type and knife edge type. And "high efficiency filter" has wood, aluminum alloy, steel plate and stainless steel frame, mainly used in hospitals, electronics, food, precision machinery, semiconductors and other occasions requiring high cleanliness filtration. The "high efficiency filter" has a large filtering area and low resistance, so it has a long service life.
high efficiency filterUsing high-end dust removal high-frequency vibration, this technology can enter the filter bag appearance of relatively large dust particles as much as possible to clean. And it will not have any bad effect on the entanglement fastness of the fiber, and it can insist that the filter bag has good peeling resistance. At the same time, in the dry and semi-dry desulfurization system, it has the effect of further reducing the acrobatics contained in the flue gas.
For the leak detection of the high-efficiency filter, we must confirm the high-efficiency filter and the supporting static pressure box after installation, and carefully check to see if there is any leakage and whether the leakage is within the specified allowable range. Once the high efficiency filter is confirmed to be qualified, we can ensure that the clean room can be operated safely. But we also have to make a distinction, because the leak detection after installation and the efficiency test before the manufacturer are completely different. In general, the latter is only in the reverse osmosis filter efficiency and related performance of these aspects of the test, the former is relatively the installation of a variety of factors in the process of leak detection.
high efficiency filterThe service life is changing. For the clean room in operation, the value of the end high-efficiency filter is relatively low, and it may all add up to less than two hours of output value of the user, but if the filter is replaced, the risk and overhead will be very high. Therefore, once the filter is to be replaced, it is necessary to stop production, and the loss of production is definitely higher than the cost of spare parts for the filter.
