The utility model discloses a pipe-type catch pot outside tank. The pipe-type catch pot mainly comprises a cylinder body, a cyclone, a hot water nozzle, and a packing layer, wherein the cylinder body has a columnar upper part, and a reversed conical lower part; a water outlet pipe is connected with the bottom of the reversed conical lower part; a juice steam inlet pipe is inserted into the cylinder body from the center of the top of the cylinder body; the lower part of the juice steam inlet pipe is connected with the cyclone; the hot water pipe is inserted into the center of the juice steam inlet pipe; the hot water nozzle is connected with the hot water pipe; the packing layer is placed on a support between the inner wall of the tank and the outer wall of a steam inlet pipe; a plurality of diversion plates are arranged on the inner wall of the tank below the packing layer at an interval of 100 mm to 300 mm; and a juice steam outlet pipe is mounted at the upper part of the cylinder body. Compared with the prior art, the pipe-type catch pot can reduce sugar entrainment loss, and the II-effect evaporation condensing water can meet the requirement of inlet water of the boiler, thereby saving the energy consumption for preheating the inlet water and reducing the water softening cost. In addition, the pipe-type catch pot can reduce the sugar content in the condensing water for boiling sugar, improve the repeated utilization rate, reduce the consumption of water resources and radically solve the pollution problem of the sugar-containing condensing water.
