The invention provides an escape pipe opening liquid recycling device. The escape pipe opening liquid recycling device comprises an escape chimney opening, a water receiving tank, a liquid guide pipe and a U-shaped water sealed joint. The escape pipe opening liquid recycling device is characterized in that the water receiving tank is connected to the outer part of an escape chimney opening; the bottom of the water receiving tank is provided with a liquid guide pipe which is movably connected with the water receiving tank; the liquid guide pipe and the inner part of the chimney opening is tightly fit; the lower part of the liquid guide pipe is provided with the U-shaped water sealed joint which is movably connected with the liquid guide pipe. The escape pipe opening liquid recycling device has the beneficial effects that water flowing out of the chimney opening centrally returns to the inner wall of the chimney, and flows back close to the wall of the water sealed joint, and air cannot blow from the liquid guide pipe, so that the issue of water at the chimney opening is recycled is solved; equipment is effectively prevented from being rusted by water.
