Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, and in particular to a desalination device for treating high-salinity industrial wastewater. Background Technology

[0002] In the food processing industry, such as seafood processing and pickled food production, high-salinity wastewater is generated. Direct discharge of this wastewater without treatment will lead to water pollution. Desalination equipment can help treat this wastewater, reduce environmental pollution, and enable the recycling and reuse of some resources.

[0003] A high-salinity industrial wastewater treatment and desalination device includes a condensate inflow ring, an activated carbon plate, a floating plate, etc. The wastewater is heated and evaporated into water vapor, while the salt does not evaporate due to its high boiling point and remains in the evaporator. After the vapor is cooled by the condensation system, it turns back into water, resulting in desalted fresh water. It is suitable for wastewater with high salt concentration.

[0004] In existing technologies, some high-salinity industrial wastewater treatment and desalination devices focus on removing salt and impurities from wastewater through reverse osmosis, evaporation, and other methods to purify the water. However, the recycling of condensate is often neglected during the treatment process. Condensate is a byproduct of evaporation and cooling operations in industrial wastewater treatment, containing some water and recyclable resources. If it is not used properly, it will lead to the waste of water resources. Therefore, a high-salinity industrial wastewater treatment and desalination device is proposed to solve the above problems.

The crystallized salt can be collected by the scraping device and used directly for salt recovery or further treatment. This realizes the recovery of salt and reduces secondary pollution, and can effectively treat high-salinity industrial wastewater. Attached Figure Description

A condensate outlet pipe 17 is fixedly connected to the left side of the condensate purification tank 9. After the condensate is purified, it is discharged from the condensate outlet pipe 17.

[0037] Reference Figure 2 , Figure 4 , Figure 6A heating tank 18 is fixedly connected to the bottom of the condensate inlet ring 6. The left side of the heating tank 18 is fixedly connected to the right side of the condensate purification tank 9. Multiple heating tubes 19 are fixedly connected inside the heating tank 18 to heat the condensate, causing it to evaporate and leaving behind crystalline salt. The multiple heating tubes 19 inside the heating tank 18 provide a heat source to accelerate the evaporation process. A crystalline salt receiving disc 20 is fixedly connected to the bottom of the heating tank 18 to receive the residual crystalline salt after evaporation. The disc is designed with a sloping shape, with one end of the crystalline salt outlet pipe 26 being the lowest point of the slope, allowing the crystalline salt to flow smoothly out of the outlet pipe 26.

[0038] Working principle: Multiple water cooling pipes 2 carry away heat through circulating water to maintain the temperature of the device. Water pump 4 draws cooling water from the circulating water tank 5 and pushes the circulating water through the circulating water pipe 3 to flow in the water cooling pipes 2, ensuring continuous circulation of cooling water in the device, thereby enhancing the cooling effect. The inclined design of the conical top cover 1 helps guide the condensate and reduce accumulation. The condensate flows into the ring 6 and is then guided to the condensate purification tank 9 through the condensate water pipe 7 for further treatment. In the condensate purification tank 9, the condensate passes through the filter plate 10 and the activated carbon plate 11 to remove impurities and harmful substances from the water, ensuring that the purified water meets the usage standards. The floating plate 16 rises, driving the semi-circular rising rod 15 to rise and open the rotating plate 14. The drugs in the chemical drug storage tank 13 enter the condensate purification tank 9 through the fixed pipe 12 to further improve the water quality. The purified water is discharged through the condensate outlet pipe 17.

[0039] Wastewater is heated in the heating tank 18 by multiple heating tubes 19 to evaporate the water and leave behind crystalline salt. The motor 22 drives the bottom scraper 24 and the side wall scraper 25 through the output shaft 23 to scrape off the crystalline salt on the inner wall of the heating tank 18. The evaporated crystalline salt flows into the crystalline salt receiving disc 20 through the bottom hole. The inclined design of the disc ensures that the crystalline salt can flow out smoothly. Finally, the treated crystalline salt is discharged through the crystalline salt outlet pipe 26.
