<p><P>PROBLEM TO BE SOLVED: To provide a double chamber type waste gas treatment apparatus which can prevent occurrence of thermorunaway at the time of regeneration treatment of an adsorbent and shorten the regeneration time of the adsorbent. <P>SOLUTION: When abnormal temperature increase occurs at the time of regeneration treatment, thermorunaway at the time of the regeneration is prevented by conducting some of operations such as nitrogen gas injection to a regeneration duct 29 from a nitrogen gas lead-in pipe 52, cease of circulation of a component gas by stopping a blower 33 for regeneration and at the same time closing a flow rate control damper 53, and shutdown of a power source of a heating part 31 in combination. Further, the time of regeneration of the adsorbent is shortened by efficiently carrying out cooling/heating of the component gas flowing in the regeneration duct 29 by installing a heat releasing bypass pipe 56 bypassing the regeneration duct 29 of the regeneration part 11 and equipped with a heat releasing fin 54a and a bypass damper 55. Furthermore, cooling/heating of the component gas is efficiently carried out by surrounding the heat releasing fin 54a with a heat insulator and blowing cold air/hot air to the heat releasing fin 54a. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
