Abstract

The invention relates to a saline water desalting system which comprises a container, a condenser, a membrane distillation assembly, a heater and pipelines, wherein the container is provided with a bitter saline water inlet, a desalted wastewater discharge hole and a fresh water discharge hole, the condenser and the membrane distillation assembly are arranged inside the container, the heater is used for heating bitter saline water entering the end part of the membrane distillation assembly and generating steam; the pipelines include a first pipeline for communicating the bitter saline water inlet with the heater, a second pipeline for communicating the heater with the membrane distillation assembly and a third pipeline for communicating the membrane distillation assembly and the wastewater discharge hole; the condenser is positioned above the membrane distillation assembly; the heater is arranged at the outer side of the container and is a solar heater; and the condenser is arranged on the first pipeline. According to the saline water desalting system, on the one hand, as the solar heater is used, energy sources are saved; and on the other hand, the condenser is arranged on the first pipeline, heat energy is transferred onto the first pipeline by using a condensation and heat dissipation principle, so that the temperature of bitter saline water in the first pipeline is improved and resources are sufficiently utilized.

Description

technical field [0001] The invention belongs to the technical field of water desalination, in particular to a salt water desalination system. Background technique [0002] Desalination of salt water is mainly to desalinate water with high salt content, and the desalinated water meets the national drinking water standards, for example, brackish water (or sea water). my country's brackish water is mainly distributed in the northern and eastern coastal areas. There are more than 38 million people drinking brackish water in rural areas, such as Xinjiang, Inner Mongolia, Gansu and other central and western regions. The bitter and salty water has a bitter taste and is difficult to drink directly. Long-term drinking can lead to gastrointestinal dysfunction and weakened immunity. However, due to limited energy resources and sparsely populated areas in the western region, it is not suitable for large-scale fresh water purification. [0003] Currently, there are three methods of bri...
