<p>PROBLEM TO BE SOLVED: To simplify the inner structure of a reaction tank to make it economical, and also to feed the uniform quantity of air for oxygen over the whole liquid storing part, and furthermore, to uniformly feed makeup water for humidification added to the air for oxygen and to reduce the used quantity thereof. SOLUTION: In a reaction tank, a liquid storing part 4 for housing a liquid absorbent is formed in the bottom part thereof, and a waste gas introducing pipe and an oxidizing air pipe for feeding oxidizing air into the liquid absorbent are arranged. In this case, plural support beams 22-25 disposed inside it are constituted of a tubular member to form flow passages for oxidizing air and to make them introducing pipes for oxidizing air, and also one takeoff 30 pipe for oxidizing air provided with an air nozzle for oxidizing air at the head part thereof is connected to one of the support beams 22-25.</p> |
