[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-5 The high-efficiency distillation equipment shown includes a distillation mechanism 1, a guiding mechanism 4 at the feed inlet of the distillation mechanism 1, a waste heat recovery mechanism 3 around the guiding mechanism 4, and a collection tank 2 outside the distillation mechanism 1. The guiding mechanism 4 includes a feed pipe section 41, a heat absorption pipe section 44, and a feed pipe section 42 that are connected to each other in sequence. One end of the feed pipe section 42 is connected to the inside of the distillation mechanism 1. Six spiral inserts 43 are arranged around the heat absorption pipe section 44. The waste heat recovery mechanism 3 includes a condenser ring box 31 and spiral condenser pipes 32 surrounding the heat absorption pipe section 44 inside the condenser ring box 31. The distillation mechanism 1 includes a distillation tank 11 and a steam conduit 15 at the top of the distillation tank 11. The feed pipe section 41, the heat absorption pipe section 44, and the feed pipe section 42 are pipes used to connect to an external pump body to inject the liquid to be distilled into the distillation tank 11.

[0021] In this embodiment, an arc-shaped slot 45 is provided around the heat absorption tube section 44. One side of the spiral insert plate 43 is inserted into the arc-shaped slot 45. The spiral insert plate 43 is penetrated by the spiral condenser tube 32. The spiral insert plate 43 is spiral-shaped and has holes for the spiral condenser tube 32 to pass through, thereby introducing the heat in the spiral condenser tube 32 into the interior of the heat absorption tube section 44. An inner conical guide tube 46 is fixedly connected to the middle of the heat absorption tube section 44. An outer conical guide tube 47 is provided between the inner conical guide tube 46 and the heat absorption tube section 44. 47 is fixedly connected to the inner side of the spiral insert plate 43; the outer periphery of the outer conical guide tube 47 is connected to the spiral insert plate 43 by bolts, thus facilitating disassembly; when the chemical solution enters from the feed pipe section 41, it is blocked by the outer conical guide tube 47 and enters the heat absorption chamber 48. The solution then passes through the bottom of the outer conical guide tube 47 to reach the inner side of the outer conical guide tube 47, and finally flows into the feed pipe section 42 from the inner side of the inner conical guide tube 46, thereby increasing the contact time between the solution and the outer conical guide tube 47, thus enabling better preheating; the inner conical guide tube 46... The interior is a discharge channel 49, and the space between the outer conical guide tube 47 and the heat absorption tube section 44 is a heat absorption chamber 48. A spiral insert plate 43 connects the outer shell of the heat absorption tube section 44 to the periphery of the outer conical guide tube 47, dividing the heat absorption chamber 48 into six zones. One end of the spiral condenser tube 32 has an inlet end 33, and the other end has a connecting end 34. The inlet end 33 connects to a steam conduit 15. A drain port 35 is located on one side of the condenser ring box 31. The condenser ring box 31 is fitted around the heat absorption tube section 44, connecting... There are seals at the condenser ring box 31, and cooling water is inside the condenser ring box 31. A drive motor 12 is installed on the top of the distillation tank 11, and a stirring paddle 13 with uniform vertical arrangement is installed at the output end of the drive motor 12. A discharge end 14 is provided at the bottom of the distillation tank 11. An electric heating element is provided in the base of the distillation tank 11, so as to heat the chemical solution entering it, while the operation of the drive motor 12 is to stir the chemical solution. The input end of the collection tank 2 is connected to the connecting end 34. The collection tank 2 collects the condensed liquid, and its output end has a solenoid valve.

[0022] The working principle of this utility model is as follows: When the solution is pumped to the guide mechanism 4, it will pass through the feed pipe section 41, the heat absorption chamber 48, the discharge channel 49, and the feed pipe section 42 in sequence before reaching the interior of the distillation tank 11. At this time, the heating device inside the distillation mechanism 1 heats the solution. As the temperature rises, the solution will evaporate. The evaporated gas will be introduced into the interior of the spiral condenser tube 32 through the steam conduit 15. At this time, the liquid inside the condensation ring box 31 will absorb the heat of the evaporated gas and then conduct this heat through the spiral insert plate 43 to the interior of the heat absorption pipe section 44, thereby heating the solution in the heat absorption chamber 48 and preheating it. In this way, the heat in the steam during condensation can be utilized, and the solution at the time of feeding can be preheated, realizing energy recycling. In addition, when the solution passes through the heat absorption tube section 44, it passes through the heat absorption chamber 48, the discharge channel 49 and the feed tube section 42 in sequence before entering the interior of the distillation tank 11. This process prolongs the flow distance of the solution, thereby increasing the contact time between the untreated solution and the spiral baffle 43, and further improving the efficiency of waste heat recovery and utilization of preheated solution.

[0023] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
