Abstract

The invention discloses a sleeve type bubbling-humidifying seawater desalinating device. The device comprises a solar heat collector, a bubbling evaporation cylinder, bubblers, a condensing cylinder, hot pipes, corrugated heat conducting plates, a seawater cooling cylinder, a fresh-water tank, a concentrated seawater heat exchange slot, a solar photovoltaic panel, a storage battery, an air pump, a water pump and an automatic water changing system, wherein the bubbling evaporation cylinder, the condensing cylinder and the seawater cooling cylinder form a sleeve structure from inside to outside; the solar heat collector is connected to the bubbling evaporation cylinder through a pipeline; the hot pipes and the corrugated heat conducting plates are arranged on the wall of the condensing cylinder; and the bubblers are mounted at the bottom of the bubbling evaporation cylinder. According to the sleeve type bubbling-humidifying seawater desalinating device, solar energy is utilized for supplying heat and power, and bubbling humidification and dehumidification principles are adopted, so that the device is compact in structure, high in energy utilization rate, can be used for acquiring fresh water from seawater and has very important significance to the fresh water production for fresh water resource poor regions such as islands.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a sleeve type bubbling humidification solar seawater desalination device. Background technique [0002] With the shortage of fresh water resources, seawater desalination technology has been paid more and more attention by various countries. Desalination of seawater is the process of separating the salt and water in seawater to obtain fresh water and concentrated brine. Traditional seawater desalination methods mainly include distillation, reverse osmosis, electrodialysis, freezing, hydrate and solvent extraction. At present, the distillation method has achieved industrial production, but the traditional distillation method has high energy consumption, low economic benefits, complex structure of seawater desalination equipment, difficult operation, large seawater corrosion and low heat transfer efficiency. Reverse osmosis has gradually replaced distillation as th...
