<p>PURPOSE:To control the deodorizing device so that the approximately 100% adsorbing capacity of an adsorbent be utilized regardless of the variation of malodorous components being contained and gas is not exhausted to the outside as it remains as it is malodorous gas by a method wherein a progress condition of deodorizing is confirmed by detecting the malodorous components and the residual time of an effective adsorption capability of the tower is estimated by the thickness of an adsorbent layer. CONSTITUTION:Inlet gas at the first gas sampling point 13 is first analyzed by means of a gas analyzer 17 according to a gas sampling point selector 16, and the value is inputted to a computer 18 and memorized. The gas sampling point selector 16 functions by the instructions 19 of the computer 18, gas in an adsorbing layer at the second gas sampling point 15 mounted into the layer 11 is analyzed by means of the gas analyzer 17, and the value is inputted to the computer 18 and memorized. The ratio Cx/Co of the concentration Cx of the malodorous components of the gas in the said layer to the concentration Co of the malodorous components of the said inlet gas is computed by means of the computer 18. When the value reaches 0.5, an alarm is given while the signals of the residual life of an adsorption tower 10 are put out.</p> |
