[0022] The water collecting tank comprises a shell component, and the water collecting tank is arranged below the drainage mechanism and is used to receive the sewage discharged by the drainage mechanism;

[0023] The sealing water is filled in the water collecting tank to seal the outlet end of the drainage mechanism and form a sealing water column in the drainage mechanism;

[0024] The drain port is arranged on the side wall of the water collecting tank and is used for draining water exceeding the setting position.

[0025] Compared with the prior art, the beneficial effect of the present invention lies in that, in the flue gas and sewage separation drainage device provided by the present invention, a drainage mechanism and a receiving mechanism are arranged.

During use, it is used to calculate the water seal height corresponding to the telescopic tube 13 under different pressures according to the detection result of the detection module 11, and adjust the length of the telescopic tube 13 extending into the receiving mechanism 2 according to the calculated water seal height, so as to ensure that the sewage will not destroy the negative pressure environment in the flue gas channel 3 during the discharge process; the setting position of the control module 12 can be on the outer wall of the flue gas channel 3, or on other positions, such as the telescopic tube, and its setting method can be clamping, pasting and threaded connection. One end of the telescopic tube 13 is connected to the flue gas channel, and the other end extends into the receiving mechanism, which is used to output the sewage in the flue gas channel 3 and is sealed by the water seal in the receiving mechanism 2 to prevent the negative pressure in the flue gas channel 3 from being destroyed; the connection method of the telescopic tube 13 can be clamping, plugging and threaded connection.
