[0019] Reference Figures 1-5 An energy-saving evaporator crystallizer includes a crystallization structure 1, a heating component 2 inside the crystallization structure 1, and a circulation component 3 between the heating component 2 and the crystallization structure 1. The crystallization structure 1 includes a crystallization shell 101, a feed pipe 102 welded to the outer surface of the crystallization shell 101, a coolant pipe 103 at the bottom of the inner surface of the crystallization shell 101, and a demister plate 104 fixed to the top of the inner surface of the crystallization shell 101 by bolts. A control valve 105 is connected to the bottom end of the crystallization shell 101 by a flange, and a discharge pipe 106 is connected to the bottom end of the control valve 105 by a flange. The crystallization structure 1 and the heating component 2 are combined for the crystallization of materials. The heating assembly 2 includes a support plate 201 and a gas distribution box 202. The support plate 201 is fixed to the inner surface of the crystallization shell 101 by bolts. Multiple heat-conducting pipes 203 are welded between the support plate 201 and the gas distribution box 202. The heat-conducting pipes 203 are connected to the top space of the crystallization shell 101 and the gas distribution box 202. One end of the feed pipe 102 is located between the multiple heat-conducting pipes 203. A bottom pipe is welded to the bottom end of the gas distribution box 202. The bottom pipe passes through the crystallization shell 101 and is fixedly connected to the crystallization shell 101. One end of the bottom pipe is connected to the air inlet pipe 204 through a flange. Multiple connecting rods 206 are welded to the outer surface of the gas distribution box 202. One end of the multiple connecting rods 206 is welded to the same connecting ring 205. The connecting ring 205 is fixed to the inner surface of the crystallization shell 101 by bolts. The heating assembly 2 plays the role of heating the material. The circulation assembly 3 includes a side shell 301. A connecting pipe 302 connects the side shell 301 to the crystallization shell 101 via a flange. A one-way valve 303 is connected to the bottom end of the side shell 301 via a flange, and the one-way valve 303 is connected to a fixed pipe on the outer surface of the gas distribution box 202 via a flange. The one-way valve 303, the connecting pipe 302, and the outer surface of the side shell 301 are all provided with the same heat insulation shell 4. Through the design of the external heat insulation shell 4 of the circulation assembly 3, the steam inside the side shell 301, the connecting pipe 302, and the one-way valve 303 can be insulated, reducing temperature loss during steam recycling and further protecting the steam heat in the evaporator crystallizer. To fully utilize the steam, the inner surface of the side shell 301 is fixed with a perforated plate 304 and a support frame 306 by bolts. The bottom of the support frame 306 is fixed with a waterproof fan 307 by bolts, and the upper surface of the perforated plate 304 is fixed with multiple heating rods 305 by bolts. The top and bottom of the connecting pipe 302 in the circulation assembly 3 are connected to the crystallizing shell 101 and the gas distribution box 202 by the connecting pipe 302 and the one-way valve 303 respectively, which reduces the path length during steam circulation. The use of the waterproof fan 307 increases the steam flow rate, making the heat utilization of the steam more complete and ensuring the energy-saving use of the evaporator crystallizer.

[0020] The outer surface of the crystallization shell 101 is provided with a ventilation assembly 5, which includes multiple ventilation pipes 501. The ventilation pipes 501 are welded to the outer surface of the crystallization shell 101. The bottom ends of the multiple ventilation pipes 501 are welded to the same ventilation shell 502, and the bottom end of the ventilation shell 502 is snapped with a filter plate 503. Through the design of multiple ventilation pipes 501 in the ventilation assembly 5, the ventilation assembly 5 can enter air from multiple positions, which not only ensures the air intake of the ventilation assembly 5, but also makes the air intake of the ventilation assembly 5 more uniform, so that the steam in the crystallization shell 101 can be fully absorbed by the circulation assembly 3, which facilitates the use of the evaporation crystallizer. The filter plate 503 can filter the air entering the crystallization shell 101.

[0021] The working principle of this embodiment is as follows: The operator first connects the boiler steam exhaust pipe to the inlet pipe 204. Steam enters the gas distribution box 202 from the inlet pipe 204, then enters the heat conduction pipe 203. The steam heats the heat conduction pipe 203. The steam then enters the upper part of the crystallization shell 101. At this time, the waterproof fan 307 generates suction, drawing air in through the ventilation assembly 5. The steam inside the crystallization shell 101 is then drawn into the side shell 301 through the connecting pipe 302. The steam then passes through the heating rod 30... At 5 o'clock, the steam is heated by the heating rod 305. The heated steam re-enters the steam distribution box 202 through the one-way valve 303, and then enters the heat conduction pipe 203 to heat the heat conduction pipe 203. In this way, the heat of the steam can be fully utilized. Then, the coolant tank is connected to the coolant pipe 103. The coolant in the coolant tank enters the coolant pipe 103 through the pump body to cool the coolant pipe 103. The other end of the coolant pipe 103 is connected to the collection box for collection. In use, the operator feeds the material into the crystallization shell 101 through the feed pipe 102. After entering the crystallization shell 101, the material is located between multiple heated heat conduction pipes 203, which heat the material. The heated material is then conveyed downwards within the crystallization shell 101, where the cooling liquid pipe 103 absorbs the heat, causing the material to crystallize. The crystallized material is located at the bottom inside the crystallization shell 101. Then, the operator can open the control valve 105 to discharge the material from the crystallization shell 101 through the discharge pipe 106. This completes the use of the evaporator crystallizer.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
