Two-stage distilled brackish water desalting device

Abstract

The invention discloses a two-stage distilled brackish water desalting device, and belongs to the technical field of removing salt through brackish water desalination and evaporation. The two-stage distilled brackish water desalting device comprises a first-stage distillation chamber, wherein the first-stage distillation chamber is connected with a brackish water inlet pipe; the first-stage distillation chamber is connected with a first-stage condensation chamber through a steam pipe I; the first-stage condensation chamber is connected with a second-stage distillation chamber through a condensation water pipe I; the second-stage distillation chamber is connected with a second-stage condensation chamber through a gas taking pipe; a salt discharging pipe is also arranged at the bottom part of the first-stage distillation chamber. The first-stage distillation chamber is used for evaporating introduced brackish water and generating a mixed gas of steam and air, and condensed water is continuously introduced in the second-stage distillation chamber for treatment as the obtained condensed water can contain impurities of salt carried by the steam, so that purified distilled water can be obtained. The two-stage distilled brackish water desalting device disclosed by the invention is reasonable in structural design, simple in operation, convenient in maintenance and low in cost, is small-sized and environment-friendly, and is particularly suitable for being used in a family.

Description

technical field [0001] The invention belongs to the technical field of desalination and evaporation desalination of brackish water, and relates to a double-stage distillation brackish water desalination device. Background technique [0002] The distribution of fresh water resources in my country has obvious regional differences between the north and the south. The south is rich and the north is relatively scarce, especially in the Yulin area of ​​Shaanxi Province. In Shangyanwan Town, Yuyang District, Yulin City, there are huge reserves of rock salt. Both rivers and groundwater in this area are bitter and salty water with excessive fluorine content. The villagers in this area drink the underground brackish water for generations. According to incomplete statistics, residents of Shangyanwan area suffer from dental fluorosis and skeletal fluorosis. Long-term drinking of brackish water has caused a huge threat to the lives of people in Shangyanwan area. Therefore, how to make t...

Problems solved by technology

Although there are good seawater desalination technologies, such as low-temperature multi-effect and reverse osmosis membrane technologies, they are expensive and cumbersome to maintain, making it difficult to enter the homes of rural residents.
