Sea water desalination and poor water purification device and method

Abstract

The invention relates to a device of seawater desalination and poor quality water purification and a method thereof. A treatment pool has at least a transparent surface on the top; a three-dimensional network body is placed inside the treatment pool and contains10 percent to 99 percent of porosity and specific surface area thereof is not less than 0.05m<2> / g of a pass-through micro-pore. A water inlet, an air inlet and a high moisture airflow outlet are arranged in the treatment pool. The high moisture airflow outlet is connected with a condensing chamber, which is connected with a refrigerator. The lower part of the refrigerator is provided with a purifying water outlet. Raw water is filtered in advance to remove relatively large impurities and then is fed into the treatment pool so as to be fully permeated to the three-dimensional network body; the liquid absorbed inside the three-dimensional network body evaporates under the function of the airflow; the high moisture airflow going out of the three-dimensional network body after cooled is sent into the condensing chamber to become fresh water or pure water, and the fresh water or pure water comes out of the condensing chamber is absorbed by active carbon and / or is treated by ultraviolet sterilization in become drinking water. The invention is characterized by small energy consumption, high efficiency and good stability.

Description

(1) Technical field

[0001] The invention relates to a device and method for seawater desalination and water purification. (2) Background technology

[0002] As we all know, it is very difficult to directly convert seawater, brackish water and other low-quality water into drinkable pure water. The sea or brackish water must first be completely desalinated. From a global perspective, there are many traditional water desalination methods, mainly three types of methods: distillation, electrodialysis and reverse osmosis. At present, the desalination of brackish water mostly adopts reverse osmosis and electrodialysis, mainly reverse osmosis. In seawater desalination, the main methods are distillation and reverse osmosis. Here are the pros and cons of the three:

[0003] * Distillation

[0004] Distillation methods, including multi-effect evaporation ME, flash evaporation FLASH and pressure steam distillation VC, etc., are the process of heating brackish water or seawater to m...
