Claims

[Scope of Claim for Utility Model Registration] (1) A collection container filled with activated carbon, an inlet pipe whose one end is connected to one end of the collection container, and which sends gas containing harmful gas into the collection container; A first on-off valve provided in the middle of the inlet pipe, a discharge pipe whose one end is connected to the other end of the collection container and whose other end is open to the atmosphere, and a second valve provided in the middle of this discharge pipe. an on-off valve, a jacket provided to surround the collection container, a heater provided at the bottom of the jacket to heat and evaporate the water collected at the bottom of the jacket, and a heater provided on the side of the jacket that is lower than the bottom. A drain pipe is provided slightly above, a third on-off valve is provided in the middle of the drain pipe, and a third on-off valve is provided in the middle of the inner circumferential surface of the jacket, which directs cooling water toward the outer circumferential surface of the collection container. A cooling nozzle that sprays air, one end of which is connected to the recovery container, and the other end of which is connected to a recovery device that condenses and recovers harmful gases.
A hazardous gas recovery device consisting of recovery pipes connected to each other, and a fourth on-off valve and a vacuum pump provided in the middle of the recovery pipes. (2) A water pump is installed in the middle of the circulation pipe installed in place of the drain pipe, and the downstream end of the circulation pipe is communicated with the cooling nozzle, and the water vapor present in the jacket is condensed into the jacket. 2. The hazardous gas recovery device according to claim 1, further comprising a cooler for controlling the harmful gas. (3) The harmful gas recovery device according to claim 2, wherein instead of omitting the cooling nozzle, circulation pipe, and water pump, the cooling pipe constituting the cooler is directly wound around the recovery container.
