The wet sterilization is realized by vertically arranging an air filter outside the liquid strain culture tank and directly connecting a filter element with steam. The sterilization mode has the advantages of direct steam, high temperature, no dead angle, quick heating, thorough sterilization and relatively short sterilization time; the shortcoming is that direct steam can produce a large amount of comdenstion water, needs personnel constantly to get rid of the moisture that produces in the filter element casing, when formally ventilating the cultivation for the jar body, needs weather the filter core in advance to improve filter element filter fineness, it is loaded down with trivial details relatively, air cleaner's fixed mounting structure is also more complicated.
