Description

technical field

The utility model relates to the field of seawater desalination, in particular to a solar bubbling humidification-semiconductor seawater desalination device.

Background technique

Freshwater resources are scarce, and seawater desalination technology has actually become a key technology for many countries in the world to solve the problem of water shortage.

Seawater desalination is the process of separating the salt and water in seawater, and finally obtain fresh water and concentrated brine. The main traditional seawater desalination methods include distillation, reverse osmosis, electrodialysis, freezing, hydrate and solvent extraction. . Among them, the reverse osmosis method uses the difference in the solubility of water and salts in the molecular lattice gaps in the semipermeable membrane to separate them; the distillation method uses the different boiling points of the components in seawater to achieve the separation of water and salt components. 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. The reverse osmosis method has gradually replaced the distillation method as the most widely used technology in the seawater desalination market due to its simple equipment structure and easy maintenance.

The bubbling solar seawater desalination technology uses solar energy as energy and uses the principle of humidification and dehumidification to desalinate seawater. The basic idea is to use air to pass into hot seawater to form bubbles, and absorb the heat of seawater and evaporated water vapor during the rising process of the bubbles, which is the humidification process; collect water vapor and condense to obtain fresh water, which is the dehumidification process . Wet dehumidification seawater desalination method is currently a research hotspot.
