Seawater desalination treatment system and method

Abstract

The invention relates to a seawater desalination treatment system and method.The device comprises a waste heat recovery device, the waste heat recovery device absorbs heat of high-temperature gas and generates power steam, and the power steam enters a steam compressor through a first pipeline and drives the steam compressor to generate first-effect heating steam; first-effect heating steam enters a heat exchange pipe arranged in the evaporation system through a second pipeline, the first-effect heating steam releases heat in the heat exchange pipe and heats seawater outside the heat exchange pipe, the seawater enters a spraying pipeline from an original seawater input pipeline through a third pipeline, one end of the spraying pipeline is connected with a sprayer, and the other end of the spraying pipeline is connected with a second pipeline. The sprayer is arranged in the evaporation system, steam generated by seawater outside the heat exchange pipe enters the condenser through a fourth pipeline, and the condenser is connected with a fresh water discharge pipeline. The system is stable in operation, convenient to maintain, low in energy consumption and suitable for seawater desalination in environments such as islands and the like.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and relates to a seawater desalination treatment system and a method thereof. Background technique [0002] Due to special physical and geographical constraints, many islands in the South my country Sea lack fresh water. Some islands even rely on rainwater and ships to transport fresh water all year round. It is difficult for island residents to use fresh water for living. Desalination of seawater to produce fresh water in an effective way, as an incremental, open source and alternative technology for water resources, is an effective way to solve the shortage of fresh water resources in my country's island areas. [0003] At present, the mainstream seawater desalination methods can be divided into two categories according to the desalination principle: thermal method and membrane method. . The reverse osmosis seawater desalination system has a large amount of operation and mainten...

AI Technical Summary

Problems solved by technology

However, the existing thermal seawater desalination technology has shortcomings such as high energy consumption, high water production cost, and complex system, which limits its further application in island seawater desalination where resources and energy are relatively scarce.
