[0002] In the high-salt wastewater treatment industry, multi-effect evaporation or multi-stage flash evaporation technology is generally used. The above treatment technologies require steam consumption. In recent years, with increasingly stringent environmental protection requirements, steam boilers are used less and less, and the energy consumption of electric heating is too high. In the existing technology, heat pump devices for high-salt wastewater treatment are used to treat high-salt wastewater. The heat pump device for high-salt wastewater treatment is an efficient, environmentally friendly and energy-saving wastewater treatment equipment. The device uses a heat pump circulation system and the heat exchange rate on both sides of the evaporator and the condenser to achieve efficient treatment of wastewater. In this way, not only the original heater device is eliminated, but also the cost and energy consumption are greatly reduced. The heat pump device for high-salt wastewater treatment is an advanced wastewater treatment technology with broad application prospects.

The wastewater in the treatment tank 9 generates solid matter after heating, and the ultrasonic transducer 121 emits ultrasonic waves to make the inner wall of the treatment tank 9 and the pipeline produce mechanical vibration, so that the solid matter cannot adhere to the inner side of the treatment tank 9. The concentrated wastewater and solid matter enter the inner side of the filter box 2341 through the drain solenoid valve 22. Multiple filter plates 2345 can absorb the solid matter in the concentrated wastewater. The filtered concentrated wastewater is discharged through the second drain pipe 235. The setting of the ultrasonic component 12 and the filter drainage component 23 can prevent the solid matter generated by the wastewater from being adsorbed on the inner side of the treatment tank 9 and can collect the solid matter.

[0018] Workflow: Power on the equipment before use and connect the equipment to an external control device. When high-salt wastewater treatment is required, first assemble the various components on the equipment, connect the condenser tube 212 on the outside of the condensation jacket 211 to cold water, insert the filter plate 2345 on the box cover 2343 into the inside of the filter box 2341 and align the box cover 2343 and the mounting plate 2346 on the filter box 2341 vertically, so that the sealing ring 2344 is inserted into the inside of the sealing groove 2342, and then insert the bolt 2348 into the inside of the circular hole 2347 and screw the nut 2349 on the outside of the bolt 2348, so that the outside of the sealing ring 2344 fits tightly with the inside of the sealing groove 2342, thereby completing the installation of the filter assembly 234. The next step is to connect the water inlet solenoid valve 15 to the wastewater and open the water inlet solenoid valve. The magnetic valve 15 starts the evaporator body 2, the compressor 4, the ultrasonic generator 123 and the drain solenoid valve 22. At this time, the wastewater enters the inner side of the preheating tank 14 through the water inlet solenoid valve 15, and enters the inner side of the treatment tank 9 through the water inlet pipe 13. The compressor 4 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the inner side of the hollow plate 7 located above through the first connecting pipe 3, and enters the inner side of the hollow plate 7 located below through the heat conducting pipe 8. The gas in the heat conducting pipe 8 emits heat to heat the wastewater. The wastewater fully absorbs the heat emitted by the gas and begins to evaporate. The pressure sensor 11 can detect the pressure inside the treatment tank 9 in real time. The setting of the safety valve 10 can burst and release the pressure when the pressure inside the treatment tank 9 is too high, so as to prevent the pressure inside the treatment tank 9 from In case of excessive explosion, water vapor is discharged through the steam exhaust pipe 16, and part of the water vapor enters the inner side of the preheating coil 20 inside the preheating tank 14 through the first exhaust pipe 17, thereby preheating the waste water inside the preheating tank 14, increasing the temperature of the waste water before entering the treatment tank 9, and improving the heating efficiency of the waste water. The gas releasing heat in the heat conducting pipe 8 condenses into a condensing agent, enters the inner side of the evaporator body 2 through the second connecting pipe 5 and the expansion valve 6, and becomes a low-temperature and low-pressure gas again. Such a cycle can continuously heat the waste water, and another part of the water vapor enters the inner side of the hollow frame 192 and the heat dissipation pipe 193 through the second exhaust pipe 18 and the pipe group 191 located above. The water vapor in the heat dissipation pipe 193 continuously adds heat to the evaporator body 2 inside the evaporator shell 1, thereby reducing the cost and Energy is saved. The water vapor and distilled water in the heat dissipation component 19 and the preheating coil 20 all enter the inner side of the condensing coil 213. At this time, the heat of the water vapor that has not been cooled down is quickly absorbed by the cold water in the condensing jacket 211, thereby becoming distilled water and being discharged. The condensing component 21 can condense the water vapor that has not been completely cooled into distilled water to prevent the high-temperature water vapor from escaping and scalding the staff. The water content of the wastewater in the treatment tank 9 is reduced after heating, and solid matter begins to be generated. The ultrasonic generator 123 causes the ultrasonic transducer 121 to emit ultrasonic waves through the wire 122. The ultrasonic waves cause the inner wall of the treatment tank 9 and the pipeline to generate mechanical vibrations, so that the solid matter cannot adhere to the inner side of the treatment tank 9. The concentrated wastewater and solid matter enter the inner side of the first drain pipe 231 through the drain solenoid valve 22.The condensing fins 232 on the outside of the first drain pipe 231 can continuously reduce the temperature inside the first drain pipe 231 to prevent the temperature of the discharged concentrated wastewater from being too high. The wastewater inside the first drain pipe 231 enters the inside of the filter box 2341 through the one-way valve 233. The multiple filter plates 2345 can absorb the solid matter in the concentrated wastewater. The filtered concentrated wastewater is discharged through the second drain pipe 235. The ultrasonic component 12 and the filter drainage component 23 can prevent the solid matter generated by the wastewater from being adsorbed on the inside of the treatment tank 9 and can collect the solid matter. After the device has been used for a period of time, the nut 2349 can be unscrewed and the box cover 2343 can be opened to clean the filter box 2341 and the filter plate 2345.
