Gas liquid convection-type water and salt separator

Abstract

The invention discloses a gas liquid convection-type water and salt separator. The gas liquid convection-type water and salt separator comprises an inlet pipe, a evaporation and gas liquid convection glass box, an air exhaust pipe, a heat-insulation steam cylinder, a steam return pipe, a cooling water sleeve, a pneumatic tube, a fresh water case; the evaporation and gas liquid convection glass box can be divided into a front chamber and a reach chamber, the tails of two chambers are communicated, the inlet pipe is connected with the rear chamber after passing through the cooling water sleeve, the rear chamber, the air exhaust pipe and the heat-insulation steam cylinder are connected in order, a suction pump is used for extracting heating steam from the rear chamber into the heat-insulation steam cylinder, the heat-insulation steam cylinder is connected with the steam return pipe, a bidirectional valve is arranged on the steam return pipe, when the bidirectional valve enables unidirectional opening, the heating steam is returned to the front chamber through the steam return pipe, when the bidirectional valve enables bidirectional opening, a part of hot steam is returned to the front chamber through the steam return pipe, and the other part passes through the steam return pipe and is introduced into the cooling water sleeve, the pneumatic tube and the fresh water case in order. The gas liquid convection-type water and salt separator has the beneficial effect that haline water is processed, so that salt and water can be effectively separated, salt crystal and fresh water are respectively obtained, the desalting efficiency is high, the production is simple, compared with the prior art, the operating efficiency is obviously increased, and the separator has wide application prospect.

Description

technical field [0001] The invention relates to a gas-liquid convection type water-salt separation device. Background technique [0002] my country's southern Xinjiang region is extremely scarce in water resources, and is one of the most water-scarce areas in Xinjiang and even the whole country. At the same time, southern Xinjiang is the most concentrated distribution area of ​​brackish water in my country, accounting for about half of the country's brackish water distribution area. Resource-related water shortages Coupled with the lack of water quality, it has become a bottleneck restricting the sustainable development of the economy. The country attaches great importance to the desalination and utilization of brackish water, and listed it as the national "Twelfth Five-Year" and "Thirteenth Five-Year" development planning outline. At present, the mainstream technologies for treating brackish water are distillation, reverse osmosis, electrodialysis and nanofiltration, etc., ...

Problems solved by technology

[0003] Aiming at the abundant sunlight resources in southern Xinjiang, this invention draws on the traditional sun-dried salt method to avoid the disadvantages that fresh water cannot be collected and the efficiency of salt production is low during sun-dried salt treatment, and provides a gas-liquid convection type water-salt separation device
