摘要： PROBLEM TO BE SOLVED: To restrain an exhaust route of a trapping apparatus for exhaust gas from being clogged locally. SOLUTION: A diffusion plate 13 having the cross-sectional area larger than that of an opening of an exhaust gas introduction port 10 is arranged in a cylindrical housing 5 so that the diffusion plate is opposed to the introduction port 10. Cooling coils 17-22 are arranged between the diffusion plate 13 and a flange 7. The exhaust gas 23 introduced from the introduction port 10 is dispersed conically, made to flow in an upstream zone D along an inner wall of the housing 5 and then flow dispersedly in downstream zones E1-E4 and discharged through a discharge pipe 9 and a discharge port 8. Since the exhaust gas 23 flows dispersedly in the trapping apparatus for exhaust gas, the unreacted gas contained in the exhaust gas 23 is accumulated dispersedly in the trapping apparatus for exhaust gas. As a result, the exhaust route can be restrained from being clogged locally and the service life of the trapping apparatus for exhaust gas can be prolonged. COPYRIGHT: (C)2007,JPO&INPIT
