It is preferable that the mixing time with the hot air is delayed as much as possible to maximize the cooling efficiency of the hot air and to maximize the adsorption efficiency in which fine dust of the outside air is adsorbed by the hot air.

Therefore, according to the outside air inflow body 120, the outside air supplied into the space S of the space structure 110 and the hot air exhausted from the scrubber housing 10 are mixed with each other, so that the hot air is cooled to a low temperature state, and the fine dust is hot air. It can be made to have a state that is adsorbed to.

The exhaust path structure 130 is an exhaust to allow hot air including white smoke exhausted from the scrubber housing 10 through the induction cylinder 131 and the induction cover 132 to be evenly diffused into the space (S) of the spatial structure 110 It is a means of providing a furnace to maximize the function of adsorbing fine dust and lowering temperature due to mixing with outside air.
