Abstract

The present invention provides a perfluoride treatment device and the like capable of more reliably removing acid components from decomposed gas and more smoothly replacing chemical agents for dry removal of acid components. A perfluoride treatment device, characterized in that it includes: a heating unit, which heats gas and water containing perfluoride, and uses a catalyst to hydrolyze the perfluoride to generate decomposition gas; it is arranged at the front and rear of the heating unit The heat exchange unit of the section; and the acid component removal unit for dry removal of the acid component in the decomposition gas. The acid component removal unit is equipped with a gate at the bottom of the device that can be opened and closed, and takes out the reacted chemical when it is opened. (251a-251e) (gate (251)); and the slit portion (252), which is arranged between the gates (251), has slopes (S1, S2) facing the gate (251) from above, and on the slope ( S1 , S2 ) have slits ( 252 a ) of a size that allow decomposition gas to pass through but not medicine to pass through.

Description

technical field [0001] The present invention relates to, for example, a perfluoride treatment device used for decomposing and treating perfluoride. Background technique [0002] For example, in the manufacturing process of a semiconductor device or a liquid crystal device, etching and cleaning may be performed in order to form a fine pattern. In this case, perfluorinated compounds are often used. In addition, perfluorinated compounds are generally stable and mostly harmless to the human body, so they are also used, for example, as refrigerants in air conditioners. [0003] However, among these perfluorinated compounds, when released into the atmosphere, many perfluorinated compounds have a large impact on the global environment. That is, since it exists stably in the atmosphere for a long period of time and has a large global warming coefficient, it becomes a factor of global warming. In addition, as described above, perfluorinated compounds are generally relatively stabl...
