ABSTRACT:
In order to economically remove harmful components in exhaust gases by using a simple and extremely durable system, an exhaust gas to be treated is introduced into a neutralizing tower provided with a first duct and a second duct. Harmful components in the exhaust gas chemically react with a neutralizing agent randomly stacked within the neutralizing tower, and such components become deposited on the surface of the neutralizing agent. Water is supplied from a water supply pipe to the surface of the neutralizing agent by driving a pump after passage of a predetermined period of time, and the surface of the neutralizing agent is washed thereby. Additional exhaust gases are further fed and reacted with the neutralizing agent, which has a renewed surface exposed again. The neutralizing agent can thus be repeatedly used for removal of harmful components in the exhaust gases.
