If such exhaust gas is released into the atmosphere as it is, not only will the atmosphere be polluted by metal compounds such as 5nC1O and Snug, but also other parts of the equipment will be damaged by halides such as 1ICI gas. Since these metal compounds and halides may be corroded, it is necessary to remove them.

It has been disclosed. However, since this conventional technology is a wet method in which a caustic soda aqueous solution is sprayed, it is difficult to handle and has the disadvantage of corroding parts such as electrodes.In addition, since it is an electrostatic method, the removal efficiency is poor. There are drawbacks.

、除去処理に危険物や刺激臭のある物質を用いないので
、安全でありかつ環境衛生上での問題がない。As explained above, in the present invention, after filtering the exhaust gas through a filter to remove metal compounds such as 5nOz+5nCL contained in the exhaust gas, the exhaust gas after passing through the filter is converted into a solid. Since the halides such as 11Cl gas contained in the exhaust gas are adsorbed by the adsorbent, harmful substances in the exhaust gas can be removed by a so-called dry method. Done, outfit! The structure can be simplified and the handling operation can be facilitated. Furthermore, since no hazardous substances or substances with irritating odor are used in the removal process, it is safe and poses no problems in terms of environmental hygiene.
