Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, the energy-saving saline-alkali water multi-stage freezing and desalination device and the desalination process structure schematic diagram of the process of the present invention are provided, figure 2 and image 3 A schematic diagram of the overall structure of the first-stage freezing treatment device and the second-stage freezing treatment device of the present invention is given. The shown energy-saving multi-stage freezing and desalination device and process for saline-alkali water include a pretreatment system and a freezing system. After the pretreatment system is processed, it goes to the refrigeration system for cooling and desalination. The pretreatment system includes a reservoir 1, a high-density sedimentation tank 2, a V-shaped filter 3 and a multimedia filter 4. The reservoir 1 and the high-density sedi...

Abstract

The energy-saving saline-alkaline water multi-stage freezing desalination device and process, and the device comprises a pretreatment system and a freezing system, saline-alkaline water is treated by the pretreatment system and then enters the freezing system to be cooled and desalted, and the energy-saving saline-alkaline water multi-stage freezing desalination device is characterized in that: the pretreatment system comprises a water storage tank, a high-density sedimentation tank, a V-shaped filter tank and a multi-medium filter; the water storage tank is connected with a water inlet of the high-density sedimentation tank through a pipeline, a water outlet of the high-density sedimentation tank is connected with a water inlet of the V-shaped filter tank through a pipeline, a water outlet of the V-shaped filter tank is connected with a water inlet of the multi-medium filter through a pipeline, and a water outlet of the multi-medium filter is connected with the freezing system through a pipeline; a zero-pollution saline-alkali water purification process is achieved in the whole process, safety and environmental protection are achieved, the working efficiency is high, the pressure of fresh water resource shortage is greatly relieved, and a guarantee is provided for the life of people.

Description

technical field [0001] The invention relates to a saline-alkali water desalination device, more specifically, an energy-saving saline-alkali water multi-stage freezing and desalination device and a process. Background technique [0002] Fresh water resources are increasingly scarce, but saline water resources are abundant. Daily agricultural water, industrial water, and domestic water are all inseparable from fresh water. With the water shortage brought about by population growth, the fresh water source of natural resources is far from meeting the needs of current life, but the saline-alkali water resources in natural resources Abundant, there is an urgent need for saline-alkali water desalination devices to desalinate saline-alkali water for human use. In order to solve the problems caused by the scarcity of fresh water resources, the development and utilization of saline-alkali water resources will definitely be put on the agenda in the future. Contents of the invention...
