WET TYPE SCRUBBER FOR EXHAUST GAS

摘要

The present invention relates to a wet type scrubber for wet-scrubbing noxious exhaust gas, and more particularly, to a wet type scrubber capable of effectively removing particulates and moisture contained in exhaust gas by spraying liquid into a scrubbing chamber with an eliminator. Further, the present invention relates to a wet type scrubber capable of scrubbing exhaust gas without discharge of wastewater by effectively treating sludge generated during scrubbing. A wet type scrubber for exhaust gas according to the present invention comprises a wet scrubbing chamber which is disposed such that the exhaust gas introduced through an inlet flows horizontally toward an outlet and includes a drain hole formed at a position in a side surface thereof spaced apart by a certain distance upwardly from the bottom thereof; an eliminator which is disposed within the wet scrubbing chamber and installed such that the bottom thereof is positioned below the drain hole, and includes a plurality of bent blades arranged to form a passage for the exhaust gas; an oil/water separation tank for scrubbing liquid received from the drain hole by sequentially passing the liquid through a plurality of reservoirs; a spray nozzle installed to spray the liquid into an inlet-side space of the wet scrubbing chamber; a concentrating tank for receiving sludge precipitated in the oil/water separation tank and concentrating the sludge therein; and a dehydrator for separating moisture from the concentrated sludge and discharging the sludge.
