The adsorption box 30 is capable of adsorbing organic matter in the exhaust gas. In one embodiment, the adsorption box 30 may be placed with activated carbon. The coordination of the first air duct 20, the adsorption box 30, and the exhaust gas absorption tower 40 can reduce the amount of organic matter entering the exhaust gas absorption tower 40.

[0042] The hose 21 can be extended into the air outlet of the FRP reaction container 11 or covered on the outside of the air outlet of the FRP reaction container 11 to ensure that all organic exhaust gas flowing out of the air outlet of the FRP reaction container 11 can flow into the hose 21 and the first air duct 20.

[0043] In application, the hose 21 and the first air duct 20 can both be made of stainless steel, which is safer and less flammable.
