<p><P>PROBLEM TO BE SOLVED: To provide a device and a method for controlling an absorbing liquid level in a detoxification column which can efficiently control the absorbing liquid level in the detoxification column for exhaust gas discharged intermittently. <P>SOLUTION: This device for controlling the absorbing liquid level in the detoxification column which carries out detoxification by putting the exhaust gas discharged intermittently into contact with an absorbing liquid includes the following first to third means: the first means is a detecting means for the variation value of the amount of an exhaust gas installed at the inlet part of the exhaust gas in the detoxification column, the second means is a control means of an absorbed liquid which starts or increases the supply of the absorbing liquid when the signal of the variation value of the amount of the exhaust gas from the detecting means exceeds a predetermined value A, and the third means is a control means of the absorbing liquid which stops or decreases the supply of the absorbing liquid through a delay timer when the signal of the variation value of the amount of the exhaust gas from the detecting means does not reach a predetermined value B. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
