[0019] See also Figure 1-2 , the utility model provides a technical solution:

[0020] A high-salt wastewater concentration and crystallization device comprises a device body 1, an inner cavity is opened on the top of the device body 1, a second baffle 14 and a first baffle 13 are arranged above the inner cavity of the device body 1, the first baffle 13 is located above the second baffle 14, the first baffle 13 and the second baffle 14 divide the inner cavity of the device body 1 from high to low into a first inner cavity, a second inner cavity, and a third inner cavity, the first inner cavity is connected to the second inner cavity through a first connecting pipe 5, the second inner cavity is connected to the third inner cavity through a second connecting pipe 6, and the tops of the first baffle 13 and the second baffle 14 are respectively provided with a first inner cavity and a second inner cavity. A second heating plate 16 and a first heating plate 15, a device cover 2 is provided at the top opening of the device body 1, a first steam pipe 3 is provided on the top of the device cover 2, the other end of the first steam pipe 3 is connected to the second inner cavity, a second steam pipe 7 is provided on the other side of the second inner cavity, the other end of the second steam pipe 7 is connected to the third steam pipe 9, a third steam pipe 9 is provided on the back of the third inner cavity, the other end of the third steam pipe 9 is connected to the condenser 10, the other end of the condenser 10 is connected to the third connecting pipe 11, and the other end of the third connecting pipe 11 is connected to the liquid storage tank 12.

[0021] Furthermore, the first steam pipe 3 is divided into a hard pipe and a corrugated pipe, the hard pipe is connected to the device cover 2, one end of the corrugated pipe is connected to the surface of the device body 1, and the hard pipe and the corrugated pipe are connected through the first dryer 4.

[0022] Furthermore, the second steam pipe 7 is divided into two pipes, and the two pipes are connected via a second dryer 8 .

[0023] Specifically, the water vapor generated in the first inner cavity or the second inner cavity will enter the second inner cavity or the third inner cavity through the first steam pipe 3 and the second steam pipe 7 respectively. Considering that the water vapor is generated during the evaporation and crystallization of wastewater, it is easy to have a certain impact on the crystallization if it enters the wastewater again. Then, it is dried through the first dryer 4 and the second dryer 8 respectively, and it only needs to transfer the heat.

[0024] Furthermore, a third heating plate is provided at the bottom of the inner cavity of the device body 1 .

[0025] Furthermore, a salt outlet 17 is provided at the bottom center of the device body 1 .

[0026] Working principle: When in use, first turn on the first heating plate 15, the second heating plate 16, and the third heating plate, and heat up the internal temperatures of the first inner cavity, the second inner cavity, and the third inner cavity of the device body 1. After the temperature is appropriate, open the device cover 2, pour the high-salt wastewater into the first inner cavity inside the device body 1, and then quickly close the device cover 2. At this time, the steam generated in the first inner cavity is transported to the second inner cavity through the first steam pipe 3, and the steam generated in the second inner cavity is transported to the third inner cavity through the second steam pipe 7, so as to recycle the heat and prevent heat waste.

[0027] After the waste water inside the device body 1 is completely evaporated, the surface sealing cover of the salt outlet 17 is removed to take out the crystallized salt.

[0028] It should be noted that during the evaporation and crystallization process, the liquid enters the second inner cavity from the first inner cavity through the first connecting pipe 5 and the second connecting pipe 6 in sequence, and the second inner cavity enters the third inner cavity. When the wastewater enters the third inner cavity, the water vapor generated here will enter the condenser 10 from the third steam pipe 9. The water vapor is condensed into water in the condenser 10 and enters the liquid storage tank 12 through the third connecting pipe 11.
