Problems solved by technology

At present, the most widely used desalination technology is high-pressure reverse osmosis technology. Although the cost of this technology has decreased, it still consumes more electric energy and other materials. The cost should not be underestimated, and the produced Freshwater quality is not ideal

Embodiment 1

[0026] refer to figure 1, the device for improving seawater desalination efficiency with a heat pump in this embodiment includes an evaporator I8, an evaporator II11, a condenser 5, a heat exchanger 6, a fresh water circulation tank 3, a brine extraction pump 4, a jet absorption circulation pump I10, a jet Absorption circulation pump II14, jet pump I9, jet pump II12, generator 13 and absorber 15, the condenser 5 is connected to the heat exchanger 6 through pipelines, the heat exchanger 6 is connected to the evaporator I8 through pipelines, and the evaporator I8 Connect with concentrated brine extraction pump 4 through pipelines, the vacuum chamber of evaporator I8 is connected to the injection interface of jet pump I9 through pipelines, the inlet of jet pump I9 is ​​connected to jet absorption circulation pump I10, and the jet outlet of jet pump I9 is ​​connected to fresh water circulation tank 3. The outlet of fresh water circulation tank 3 is connected to the inlet of evapor...

Embodiment 2

[0039] The difference between this embodiment and embodiment 1 is that the heat exchanger 6 and the absorber 15 are manufactured as one body, and the seawater can directly go to the absorber 15 to obtain heat after the temperature of the condenser 5 is raised. All the other are with embodiment 1.

Abstract

Provided are a device and a method for improving sea water desalinization efficiency through a heat pump. The device comprises an evaporator I, an evaporator II, a condenser, a heat exchanger, a fresh water circulation box, a strong brine extraction pump, a spraying absorption cycle pump I, a spraying absorption cycle pump II, a jet pump I, a jet pump II, a generator and an absorber. The method for improving the sea water desalinization efficiency through the heat pump is further provided. The device for improving the sea water desalinization efficiency through the heat pump is simple in structure, fewer in circulating pump, small in size, less in occupation space, stable and reliable in operation and good in output fresh water quantity. By means of the device and the method, equipment manufacture cost is reduced, and sea water desalinization cost reduces by lower than 2 yuan / ton. The device and the method are suitable to manufacture of fresh water in scale, particularly suitable to manufacture of drinkable fresh water on submarines, steamers, islands and places with poor water quality in the west of our country and the like and wide in application scope.

Description

technical field [0001] The invention relates to a device and method for improving seawater desalination efficiency by using a heat pump. Background technique [0002] With the continuous growth of the population and the rapid development of the economy, people's demand for water resources has been intensified, and the further development of the urbanization process has also accelerated the demand for fresh water resources. The shortage of fresh water resources in the world has become a growing concern. [0003] China is one of the 13 water-poor countries in the world. The per capita fresh water resources are only 1 / 4 of the world's per capita. Due to the uneven distribution of water resources, a large amount of fresh water is concentrated in the south, and the fresh water resources in the north are only 1 / 4 of the south. It can be said that the overall situation of fresh water resources is not optimistic. [0004] For this reason, people are looking for fresh water resourc...
