Closed sampling device for wet chlorine gas in electrolytic bath

The utility model relates to the technical field of chlorine gas sampling, in particular to a closed sampling device for wet chlorine gas in an electrolytic bath. Comprising an outlet connector, an inlet connector, a sampling bottle, a pure water bottle, a chlorine analysis tube and a flow guide hose, the inlet connector is arranged at the upper end of the sampling bottle, the outlet connector is arranged at the lower end of the sampling bottle, the flow guide hose is communicated with the pure water bottle, the flow guide hose is matched with the outlet connector, and the chlorine analysis tube is matched with the inlet connector. The pure water after standing is adopted, the pure water after standing is connected to the sampling bottle through the flow guide hose, the pure water is naturally pressed into the sampling bottle through liquid level difference, negative pressure in the sampling bottle is counteracted, chlorine is replaced for analysis, and the situation that the chlorine content cannot be analyz
