<p>PROBLEM TO BE SOLVED: To surely decomposed a CFC or the like even in the case of keeping a high temp. only for a short time by using a compression section of a displacement type compressor as a decomposition section, feeding the CFC or the like and an auxiliary material in the decomposition section and adiabatically compressing the CFC or the like to increase the temp. once to the decomposition temp. to cause the exothermic reaction of the CFC by the adiabatic compression. SOLUTION: In the operation of a decomposing device 10, an air stop valve 32a is opened at first, warming-up and oiling are started by driving a driving means 17 and after that, the air stop valve 32a is closed, the recovered CFC and the auxiliary material are fed to the compression section 12 with a CFC stop valve 18a and an auxiliary material stop valve 19b opened. And the CFC and the auxiliary material are mixed with each other in the ascending process of a piston 11b and simultaneously the temp. is increased by the adiabatic compression. As a result, the decomposition reaction of the CFC and the synthetic reaction with the auxiliary material are performed. When the piston 11b shifts to the descending process, the gas in the compression section 12 is adiabatically expanded to decrease the temp. to the normal temp. and discharged to an exhaust passage 13. The decomposition gas in the waste gas is neutralized the contact with a neutralizing material at the time of passing through a neutralizing case 13a.</p> |
