Abstract

PURPOSE: To remove malodorous sulfur compound components in exhaust gases efficiently by subjecting the exhaust gases contg. sulfur compound components to two-stage absorption treatment by means of a sodium hypochlorite absorbing soln. of specific pH and specific available chlorine concn.
CONSTITUTION: An exhaust gas 1 contg. odorous components such as hydrogen sulfide and methyl mercaptan is introduced into the 1st absorption column A. Caustic soda is fed into the column A from a tank 7, and sodium hypochlorite is fed from a tank 8 into the 1st absorption column washing tank 5, whereby the pH of the washing liquid is controlled 9W11, and the available chlorine concn. of the sodium hypochlorite to 100W1,000ppm. This washing liquid is sprayed from spray nozzles 3 and is contacted with the exhaust gas ascending in a packed tower 2. Thence it is introduced into the 2nd absorption column B, where the absorbing liquid of 7W9pH and 200W1,500ppm available chlorine of sodium hypochlorite is sprayed spray nozzles 3', and is contacted with the exhaust gas ascending in the packed column 2'.
