<p>PURPOSE:To effectively remove malodor especially from a vacuum vehicle by using deodorizing liquids having mutually different properties, removing oil mist at the preceding stage and malodorous components at the poststage and preventing blowing-up of the deodorizing liquids by providing many sheets of porous straightening plates. CONSTITUTION:Adequate quantities of deodorizing liquids having mutually different properties are respectively poured into a first room 21 and a second room 22. An inflow pipe 3 from a generation source of malodorous gas is extended downward the first room 21, and the gas is diffused from an air diffusing pipe having porous holes at the bottom into the deodorizing liquid. The diffused gas is introduced into an air diffusing pipe 5 in the second room 22 via a vent pipe 7 and is diffused into another deodorizing liquid. At that time, the straightening plates 9, 11 are provided respectively at the middle position of the first room 21 and also at the upper part of the air diffusing pipe 5 of the second room 22, and a baffle board 13 is also provided at the upper part of the straightening plate 11. Thus, influence due to pressure fluctuation of the inflow gas is prevented.</p> |
