Exhaust Gas Treatment Method Exhaust Gas Treatment Apparatus Apparatus for Manufacturing Glass Article and Method of Manufacturing Glass Article

The present invention provides an exhaust gas treatment method capable of sufficiently removing a sulfur component, a boron component, and the like in an exhaust gas and suppressing the investment cost and operation cost of a wet facility. The method for treating the exhaust gas of the present invention comprises: a glass melting step (ST1); a cooling step (ST2) of bringing a cooling water solution into contact with the exhaust gas to obtain an exhaust gas after cooling; a powder recovering step (ST3) of recovering a reaction product of the exhaust gas and the powder as a powder after cooling, while contacting the exhaust gas with a powder of an alkali metal salt or an alkaline earth metal salt after cooling to obtain an exhaust gas after contact; a drain treating step (ST5) of obtaining a clean gas by bringing the cooling liquid into contact with the exhaust gas after contact, and recovering the reaction solution of the exhaust gas after contact and the cooling liquid as a drain. In the drain treatment step
