The present invention is a body having an exhaust port at the top; A gas supply line for supplying gas for processing to the main body; A filling media installed in the main body to increase a contact area with the gas; A first cleaning liquid spraying unit configured to spray the first cleaning liquid into the gas supply line to remove dust and contaminants from the passing gas; A vortex-type moisture removal unit configured to separate the first cleaning liquid from the gas supplied from the main body from the gas supply line; A first cleaning liquid storage tank collecting the first cleaning liquid separated from the gas by the vortex-type moisture removal unit and discharging it to the outside; A second cleaning liquid spraying unit for spraying a second cleaning liquid onto the filler in the body to remove dust and contaminants when the gas contacts the filler; And a second cleaning liquid storage tank for collecting the second cleaning liquid sprayed from the second cleaning liquid spraying unit; and a pre-treatment cleaning device installed in the pipe and a vortex-type water removal device. According to the present invention, by pre-treating the pollutants using the reaction space in the gas supply pipe, the pollutant removal performance is excellent, the treatment efficiency can be improved at the same facility scale, and the facility is prepared for the introduction of various pollutants. Even if it is composed of several stages, it is possible to prevent the reduction in the economic efficiency and efficiency of the facility.
