Problems solved by technology

[0004] The existing technology does not have effective measures for the improvement of saline-alkali land, so it is necessary to propose a cold energy desalination system and process, which can desalinate and fix the salt water underground in saline-alkali land, and can actively promote the development of saline-alkali land salt water, etc. The development and utilization of unconventional water resources, in the areas where fresh water resources are scarce, realize the ecological management of saline-alkali land with low investment, low energy consumption and no pollution

Embodiment 1

[0038] Example 1 A cold energy desalination system for salt water treatment

[0039] like figure 1 As shown, the present invention provides a cold energy desalination system for salt water treatment, including a cold energy crystallization system 1 , an ice-water separation system 2 , and an evaporation desalination and salt fixation system 3 .

[0040] The cold energy crystallization system 1 utilizes cold energy to realize the crystallization of salt water, and the crystallized ice crystals and concentrated salt water mixture enter the ice-water separation system 2 for separation, and the separated concentrated salt water and ice crystals enter the evaporation desalination and salt fixation system 3 , concentrated salt water is evaporated to solidify salt, and ice crystals are melted to obtain fresh water.

[0041] like figure 2 and image 3 Commonly shown, the cold energy crystallization system 1 includes a box body 11, the inside of the box body 11 is provided with a p...

Embodiment 2

[0068] Example 2 A cold energy desalination process for salt water treatment

[0069] The invention provides a cold energy desalination process for salt water treatment, which specifically includes the following steps:

[0070] S1. Drill shallow shafts to pump underground salt water;

[0071] S2. Utilize cold energy for desalination by freezing; salt water enters the cold energy crystallization system and flows along each partition one by one. During the flow process, the vacuum heat pipe absorbs the heat in the salt water and transfers the heat to the upper part and releases it to the cold air through the fan, so that Salt water produces a large number of ice crystals, forming a mixture of ice crystals and concentrated salt water;

[0072] S3, Separation of ice and water: the mixture of ice crystals and concentrated salt water is separated from the mixture of ice crystals and concentrated salt water under the action of the filter plate. , Complete the efficient separation o...

Abstract

The invention discloses a cold energy desalination system for salt water treatment. The cold energy desalination system comprises a cold energy crystallization system, an ice-water separation system and an evaporation desalination and salt solidification system, the invention further discloses a cold energy desalination process for salt water treatment. The cold energy desalination process specifically comprises the following steps: S1, digging a shallow shaft to pump underground salt water; s2, freezing and desalting by using cold energy; s3, separating ice from water; s4, evaporation desalination and salt solidification; s5, using ice-melting fresh water and condensed water for irrigation and salt leaching; the system can carry out desalination and salt fixation treatment on the underground salt water of the saline-alkali soil, and realizes salt water freezing desalination and ice-melting fresh water irrigation salt leaching; the salt water freezing and desalting process is efficient; development and utilization of unconventional water resources such as saline water of the saline-alkali soil can be actively promoted, and ecological management which is low in investment, low in energy consumption and free of pollution on the saline-alkali soil is achieved.

Description

technical field [0001] The invention relates to a cold energy desalination system and process for salt water treatment, belonging to the technical field of salt water treatment and desalination. Background technique [0002] my country is a big country with saline-alkali land, and its total area ranks third in the world. According to the development concept of "clear water and lush mountains are golden mountains and silver mountains", there is still a gap in the treatment of saline-alkali land in my country. For example, there is no national standard for saline-alkali land treatment; There are many individual measures, few comprehensive measures, more short-term governance, and less long-term mechanisms. Saline-alkali land is a stubborn disease on the earth, and it is a very precious land resource. At present, my country's saline-alkali land restoration is in a critical period, and it is also a golden period. Ecological restoration of saline-alkali land is an important tas...
