In order to achieve the above purpose, the utility model adopts the following technical scheme:
an electric-catching water-sealed tank tail gas recovery device comprises an electric-catching water-sealed tank body, a water-sealed tank tail gas main pipe, a steam cleaning pipeline and a water-sealed tank; the electric catching water seal tank bodies are connected in parallel, each electric catching water seal tank body is provided with a first transverse pipe, the first transverse pipes are connected with a water seal tank tail gas main pipe through first connecting pipes, one end of the water seal tank tail gas main pipe is connected with a steam cleaning pipeline, the other end of the water seal tank tail gas main pipe is connected with a negative pressure gas pipeline, and a gate valve is arranged at the connecting position; the water seal tank is installed in the blast-cooling underground groove, the first transverse pipe is connected with the full-flow main pipe through the second connecting pipe, and the full-flow main pipe is inserted into the bottom of the water seal tank. And an observation valve is arranged at the tail end of the first transverse pipe.
And a liquid discharge pipe is arranged on the side wall of the middle upper part of the water-sealed tank.
Compared with the prior art, the beneficial effects of the utility model are that:
1) the utility model discloses an electric water catching water seal tank body is connected with a water seal tank tail gas main pipe through a first horizontal pipe and a first connecting pipe, one end of the water seal tank tail gas main pipe is connected with a negative pressure gas pipeline, and the other end is connected with a steam cleaning pipeline; and further, the tail gas of the electric water seal tank is effectively recycled, the electric water seal tank is thoroughly cleaned, the environmental protection requirement is met, and the personal safety of operating personnel is ensured.
2) The electric catching water seal tank body is connected with a full-flow main pipe through a first transverse pipe and a second connecting pipe, and the full-flow main pipe is inserted into the bottom of the water seal tank; when the drainage capacity of the electric water seal tank is small, air is prevented from entering a tail gas system from a full flow main pipe in a blast-cooling underground tank, and then the safety risk caused by the fact that air enters a negative pressure gas system is avoided.
