Problems solved by technology
After the heat exchange is completed, this part of the ambient cooling medium with heat is usually re-discharged into the environment to dissipate the heat naturally. This part of the heat is wasted to a certain extent, which does not conform to the current production concept of energy saving and environmental protection.

Embodiment Construction
[0030] Such as figure 1 As shown, a seawater desalination system using the waste heat of the refrigeration system compressor according to the present invention is based on the refrigeration system in the prior art. The refrigeration system includes four components connected in sequence: a compressor 1, a water-cooled condenser 2, a throttling element 3 and an evaporator 4. The four components form a refrigerant circulation loop. Driven by the compressor, the refrigerant circulates circulation in the circuit. The water-cooled condenser 2 includes a hot fluid pipe and a cooling medium pipe, and the hot fluid pipe and the cooling medium pipe are in contact with each other so that the fluid in the two pipes can exchange heat through the pipe wall. The two ends of the hot fluid pipeline are respectively a refrigerant inlet and the refrigerant outlet, and the two ends of the cooling medium pipeline are respectively a seawater inlet and a seawater outlet. The outlet of the compress...

The invention discloses a seawater desalination system and method utilizing waste heat of a compressor of a refrigerating system, and relates to the technical field of seawater desalination. The system comprises a water pump, a vacuum evaporation chamber, a vacuum pump, a condensing device and a water storage tank; a seawater inlet of a water-cooled condenser communicates with seawater, and a seawater outlet communicates with an inlet of the vacuum evaporation chamber; an outlet of the vacuum evaporation chamber communicates with an inlet of the condensing device through the vacuum pump, and an outlet of the condensing device communicates with the water storage tank. The method comprises the steps: extracting seawater, introducing the seawater into the water-cooled condenser to exchange heat with refrigerant steam, heating the seawater, introducing the heated seawater into the vacuum evaporation chamber, carrying out boiling evaporation, and condensing to obtain fresh water. Waste heatof the refrigerating system is utilized to desalinate seawater, the heat is fully utilized, and energy conservation and environmental protection are achieved.
Description
technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a seawater desalination system and method utilizing waste heat from a refrigeration system compressor. Background technique [0002] Fresh water is the most basic material for human survival and production, and one of the most important resources. In recent years, the lack of available fresh water has gradually become one of the problems of general concern to the society, and seawater desalination is one of the ways to solve the problem of water shortage. Seawater desalination can convert abundant seawater resources into freshwater, especially suitable for islands, ships and other environments where freshwater supply is inconvenient. On the one hand, local materials can be used to convert freshwater, and on the other hand, it can reduce the amount of freshwater carried and prevent freshwater from breeding bacteria for a long time . Seawater desalination is one of ...
