Technical field
The utility model relates to a kind of aerosol generator, in particular to a kind of aerosol generating device that generates testing efficiency of air filter with test dirt source.
Background technology
At present, the general method of testing with air strainer of ventilating is the atmospheric dust counting method, and test dirt source is an atmospheric dust.In early eighties proposition in last century, with regard at that time, the atmospheric dust counting method more tallies with the actual situation more accurate more advanced than total efficiency method of testings such as colourimetry, the heavy methods of meter this test method by domestic researcher.In addition, the object that air strainer purifies is an outdoor air mainly, and the filter clogging effect that records for the dirt source with the atmospheric dust is more consistent with actual conditions.But because atmospheric dust is unsettled, important parameters such as the concentration of atmospheric dust and size distribution change whenever and wherever possible, cause testing efficiency of air filter result's the uncertainty and the nonrepeatability of test.In testing efficiency of air filter, in order to reduce the error in the testing efficiency of air filter, the artificial gasoloid of determining with size distribution replaces atmospheric dust to be very important as test dirt source.
In the efficiency test of air strainer,, compare with atmospheric dust as test dirt source with artificial gasoloid, the dirt source stability is good, and particle dispersion degree and concentration are easy to control; Test result accuracy height, good reproducibility.Replace the efficient of atmospheric dust as test dirt source test air strainer with artificial gasoloid, testing result is more reliable, can satisfy the requirements at the higher level that filter industry proposes testing.At present, the test dirt source of American-European countries's testing efficiency of air filter is artificial gasoloid, but American-European selected gasoloid difference, and its aerosol generator is also different.
