Concentrated brine microwave desalination device

Abstract

The invention discloses a microwave desalination device for strong brine. The microwave desalination device for strong brine is used for desalinating strong brine by using microwaves. The device comprises a microwave generating area, a heating vaporization area and a condensation area, wherein a microwave radiator is arranged in the microwave generating area of the device; the heating vaporization area consists of a vapor-water separator, a spraying system, a bottom face, a reflecting face and a shell body; and a cooler is arranged in the condensation area. The device is provided with a vapor pipe, a strong brine heating pipe, a strong brine inlet, a desalinated water outlet, a supersonic wave inlet, at least two vacuumizing ports, at least one cleaning inlet, at least one cleaning outlet, at least one compressed air inlet and at least one crystal outlet. Through applying the microwave desalination device for strong brine to a strong brine system, the heat-transfer conversion efficiency can be increased by effectively utilizing the characteristics of the microwaves; and meanwhile, the investment and operating costs are saved, and breakthroughs are made in industrial zero emission and seawater desalination.

Description

technical field [0001] The invention relates to the technical field of concentrated brine desalination and environmental protection, in particular to a microwave desalination device for concentrated brine. Background technique [0002] At present, my country's economy is developing rapidly, and at the same time, with the huge consumption of energy, environmental problems are becoming more and more serious. In order to improve the current environmental situation, the country has become more and more strict on the management of the three wastes. Industrial zero emission has been accepted by many enterprises and professionals, and it has gradually begun to be implemented in the industrial field. As water is an indispensable resource in the industrial field, the discharge of concentrated brine is an important environmental indicator. The key problem of the implementation of zero discharge in my country's industrial field is that the high-concentration saline sewage at the end o...

AI Technical Summary

Problems solved by technology

[0004] Concentrated brine treatment can be roughly divided into membrane method and thermal method. From the perspective of investment and operation effect, it is bulky and expensive, or due to long system flow and high resistance, the driving power consumption increases sharply and the operating cost is high. , low efficiency, or due to complex manufacturing, difficult maintenance, or due to corrosion, scaling, critical equipment life, etc., it is limited in the treatment of concentrated brine
