Heavy salt water treatment device using ultrasonic atomization combined with solar evaporation

Abstract

Provided is a heavy salt water treatment device using ultrasonic atomization combined with solar evaporation. The device achieves the simultaneous recovery of fresh water and salt, can be used for middle and small scale desalination treatment of seawater and brackish water, and is applicable to the treatment of concentrated water generated by reverse osmosis. The device includes an ultrasonic atomization system, a solar evaporation system, a low-temperature condensation system and a photovoltaic power generation system, wherein the photovoltaic power generation system provides power for the other systems. The ultrasonic atomization system atomizes the heavy salt water into small liquid droplets, and the small liquid droplets go into the solar evaporation system; the small liquid droplets have large specific surface areas which can make them rapidly gastified in the solar evaporation system, and the salt in the small liquid droplets is separated out into small salt particles; the small salt particles impinge on a baffle and are collected according to the principle of inertial dust collection; hot steam goes into the low-temperature condensation system, a semiconductor cooling chip makes a bionic condensation plate in a low-temperature state, and the hot steam on the condensation plate is quickly condensed to form fresh water and flows into a water storage tank. The whole process is without any adverse effects, the removal rate of salt is high, the structure is simple, and the treatment of the heavy salt water is efficient.

Description

technical field [0001] The invention relates to a high-salt water treatment device, in particular to a high-salt water treatment device which can recover fresh water and salt synchronously by utilizing ultrasonic atomization combined with solar evaporation. It is suitable for desalination of seawater (brackish water), especially for concentrated water treatment after membrane treatment to prepare fresh water. Background technique [0002] The lack of fresh water resources has become an indisputable fact, especially with the modernization of industrial technology, the only fresh water resources have also been greatly damaged. At present, the fresh water that humans can directly use comes from groundwater, lake fresh water and river water. With the deteriorating environment, these fresh water resources are gradually scarce, especially in some arid areas and island areas. Arid areas are short of water due to insufficient surface and shallow groundwater, while islands and coast...
