Attorney, Agent or FirmForeign Application Priority Data1973-06-09 JAAbstractA gas-liquid contacting method and a scrubber used therefor are disclosed which are adapted to remove harmful components, such as SOx, NOx, CO, Cl2 and HCl contained in exhaust gases. According to this invention, liquid is sprayed to follow a conical form and the mist of liquid which is thus being diffused in a conical form is encompassed with a gas flowing in parallel relation therewith. To this end, at least one nozzle for spraying liquid and an encompassing tube for ejecting gas are arranged to specific forms and relations to the effect that an excellent contacting efficiency will result, without increasing energy consumption due to pressure loss. | |
