With the development of leak detection test and high efficiency air filter technology, the role of high efficiency filters in clean rooms is becoming more and more obvious. Therefore, I believe that in the near future, the development of efficient filtration technology will be better.

Cleaning function of high efficiency filter

The high efficiency filter uses high-frequency vibration to remove dust particles outside the filter bag as far as possible, does not affect the entanglement fastness of the fiber, and insists that the filter bag has good peel resistance. In dry and semi-dry desulfurization systems, it can further reduce the acrobatics contained in the flue gas.

Leak detection standards for high efficiency filters

For the leak detection of the HEPA filter, we should confirm the HEPA filter and the matching plifter after the installation of the HEPA filter to determine whether the leak is within the specified allowable range. If we confirm that the HEPA filter is qualified, then we can ensure the safe operation of the clean room. At the same time, it is necessary to distinguish between leak detection after the installation of HEPA filters and the manufacturer's efficiency test. The latter only tests the efficiency and performance of the reverse osmosis filter, while the former detects leaks from many factors during installation.

Filter leak detection process

In leak detection, we need to introduce aerosols from the upper side of the HEPA filter and detect leaks on the lower side. Do reverse osmosis media, seal gaskets and other leak detection HEPA filters have any leaks? If there is interference during the leak detection process, we can add an isolation cover in the tuyere and test in the cover. In particular, it should be noted that the leak detection between the filter and the mounting frame can be carried out separately from these two aspects, but the interference of entrainment air should be eliminated.

I believe that through the above introduction, you should have a good understanding of the relevant methods of leak detection of high efficiency filters. If there is such a problem, I believe it can also be solved. At the same time, the environmental protection requirements of all walks of life are increasing, and the role of high efficiency air filters has significantly changed in environmental protection.
