Device for detecting and comparing performance of filters as well as detection method

Abstract

The invention relates to a device for detecting and comparing the performance of filters as well as a detection method. The device comprises a filter performance detecting device, a detecting source generating device used for generating a detecting source, a detecting source processing device used for detecting post-processing detecting source, and a vacuum-pumping device used for vacuumizing before detection, wherein the filter performance detecting device comprises a sealing outer housing, a detection atmosphere chamber and a vacuum chamber; a detecting filter device used for mounting of a detected filter is arranged in the vacuum chamber; the detecting source generating device is communicated with detecting atmosphere chamber through an detecting source inlet; the detecting source processing device and the vacuum-pumping device are communicated with the vacuum chamber through detecting source discharge outlets respectively; a pre-filtration detecting instrument and a post-filtration detecting instrument are arranged at the tops of the detecting atmosphere chamber and the vacuum chamber respectively. The sealing outer housing is transparent, so that the filter effect of each filter can be observed relatively intuitively, and the filter effects of different filters can be observed relatively intuitively.

Description

technical field [0001] The invention relates to the field of filter detection, in particular to a device and a detection method for detecting and comparing the performance of filters. technical background [0002] With the increasingly serious environmental pollution, various filters have emerged as the times require, including breathing filters, air filters, water filters and so on. At present, there are many types of filters on the market, and the quality is uneven. Each manufacturer advertises that their filters have remarkable effects, but some do not follow the actual situation, exaggerate and mislead consumers. Even if some manufacturers can come up with test reports, consumers cannot be sure whether the test reports are of the variety, batch, etc., and cannot directly observe the effect. [0003] At present, the cost of various filter testing equipment is high, and some manufacturers do not purchase them out of cost considerations. They can only go to special testing...

Problems solved by technology

At present, there are many types of filters on the market, and the quality is uneven. Each manufacturer advertises that their filters have remarkable effects, but some do not follow the actual situation, exaggerate and mislead consumers.

Even if some manufacturers can come up with test reports, consumers are not sure whether the test reports are of the variety, batch, etc., and cannot visually observe the effect

[0003] At present, the cost of various filter testing equipment is high, and some manufacturers do not purchase it out of cost considerations. They can only go to special testing institutions for testing. The testing cost is high and the testing cycle is long.

[0004] Moreover, the filtration effect of the current test mainly uses several gases formulated by the standard, and it is not possible to filter and detect the specified gas according to the actual use needs.
