[0027] A crystallization apparatus, the crystallization apparatus including a first crystallization pool 300, the first crystallization pool 300 being connected to the MVR evaporator.

[0028] Furthermore, the MVR evaporator includes:

[0029] An evaporator tank includes a first heating chamber 120 and a first evaporation chamber 110. The first heating chamber 120 is located at the lower left end of the evaporation chamber. The lower end of the first heating chamber 120 and the lower end of the first evaporation chamber 110 are connected by a first connecting pipe 140. The upper end of the first heating chamber 120 and the middle of the left end of the first evaporation chamber 110 are connected by a second connecting pipe 150.

[0030] The heating assembly includes a first compressor and a plurality of first heating plates 130. The first heating plates 130 are disposed in the first heating chamber 120. The upper end of the first heating plate 130 passes through the first heating chamber 120 and is provided with a first steam inlet. The first steam inlet and the upper end of the first evaporation chamber 110 are connected by a third connecting pipe 160. The first compressor is disposed on the third connecting pipe 160.

[0031] Furthermore, the heating assembly includes a distilled water tank 170 and a first preheater 180. A first steam pipe is provided on the first steam inlet. A first condensate pipe is provided at the lower end of the first heating plate 130 through the first heating chamber 120. The first condensate pipe is connected to one end of the distilled water tank 170. One end of the first preheater 180 is connected to the other end of the distilled water tank 170. The other end of the first preheater 180 is connected to the first steam pipe.

[0032] Furthermore, the lower end of the first connecting pipe 140 is provided with a first feed pipe 141, and the left end of the first feed pipe 141 is provided with a second steam pipe, which is connected to the first preheater 180.

[0033] Furthermore, the crystallization device includes a first heater 310 and a plurality of first hydraulic cylinders 320. The first heater 310 is disposed at the lower end of the first crystallization pool 300, and the first hydraulic cylinders 320 are disposed at both ends of the first crystallization pool 300. The first hydraulic cylinders 320 are provided with first push plates 330.

[0034] Working principle: Wastewater is placed into the pretreatment tank 200, and coagulant is added. The first drive motor 210 drives the first stirring paddle 230 to rotate, causing impurities or high-valence ions in the wastewater to coagulate and settle. After the reaction, the wastewater is filtered through the first filter tank, and the clarified liquid is collected in the first clarified liquid pool 250. Water in the distilled water tank 170 is sent to the first preheater 180 for heating and evaporation, and the steam is sent to the first heating plate 130 for preheating treatment. Simultaneously, the first compressor creates a negative pressure in the first evaporation chamber 110 and the first heating chamber 120. The first feed pipe 141 draws wastewater from the first clear liquid tank 250 into the evaporator tank. Heated by the first heating plate 130, the water in the wastewater evaporates, forming low-temperature, low-pressure steam. This steam is then processed by the first compressor into high-temperature, high-pressure steam, providing secondary heating to the first heating plate 130. This utilizes the steam generated from wastewater evaporation to heat and evaporate the wastewater, resulting in greater energy savings and better heating performance; only initial preheating of the first heating plate 130 is required. Furthermore, while the steam provides secondary heating to the first heating plate 130, the steam undergoes heat exchange and condensation before flowing back into the distilled water tank 170 for reuse. Finally, the fully concentrated wastewater is placed into the first crystallization tank 300. The first heater 310 heats the first crystallization tank 300, while the first hydraulic cylinder 320 repeatedly pushes the first push plate 330, thus pushing the wastewater in the first crystallization tank 300, further enhancing its evaporation and crystallization effect. Furthermore, the lower end of the first pusher plate 330 is square-wave shaped, which provides better stirring effect for concentrated sewage or crystals.
