<p>PROBLEM TO BE SOLVED: To protect the circumferential environment without scattering to the surroundings by a closed treatment shut out from the outside by surely adsorbing and removing dust, harmful components or the like in a waste gas to cool and release to the atmosphere. SOLUTION: After the dust, or the like, in the waste gas is classified and removed with a cyclone structure 10, the waste gas is cleaned and scrubbed with an adsorbent water solution, in which an adsorbent is dissolved and incorporated, in a waste gas cleaning column 20 to be released to the atmosphere. In the waste gas cleaning column 20, a double structural waste gas treating structure 30 composed of an upper part shutting guide part 31 for adsorbing and removing harmful components, or the like, by jetting the adsorbent water solution in the waste gas and vertically meandering and a lower part flow-out guide part 35 and a filter structure 50 formed by arranging detachably and exchangably filter panels 58, in which an adsorbing body 61 is filled, in layer are vertically installed in proper stages. The adsorption waste liquid is introduced into a separation and filtration structure 70 from a waste liquid port 42 opened at the bottom of the lower flow-out guide part 35 to settle and remove the harmful components, or the like, and the purified water is jetted to the waste gas cleaning column 20 as the adsorbent water solution to be recycled. The bottom of the waste gas cleaning column 20 is communicated with a blower 26 and the waste gas after the purification is released to the atmosphere from a stack 27.</p> |
