Problems solved by technology

[0003] Existing low-energy seawater desalination devices generally use solar energy evaporation methods, such as the "solar seawater desalination system" described in the invention patent with application number 201310232944.7, which uses solar heating devices to heat and distill, and increases heat through temperature-increasing heat storage devices The utilization rate can avoid heat loss and waste, but the cost of the solar heating device used in this invention is relatively high, and the desalination of seawater only through distillation will lead to the formation of more mineral scale deposits in the distillation header as the water evaporates. Affect the pressure in the distillation header, the pressure may be too high and cause damage to the device if used for a long time

Abstract

The invention discloses a low-energy seawater desalination system, which comprises a seawater pump and a seawater desalination tank. A light energy heating mechanism is commonly connected to the tube, and the light energy heating mechanism includes a plurality of seawater heating mechanisms arranged in a matrix; the present invention also discloses a low-energy seawater desalination method, which includes the following steps: S1: seawater extraction; S2 : split heating; S3: confluence; S4: reverse osmosis filtration; S5: steam condensation; S6: fresh water collection. The present invention heats seawater through blackened metal plates and blackened metal semicircular tubes, reduces equipment costs, increases seawater evaporation speed and evaporation through atomizing nozzles, and further desalinizes seawater through reverse osmosis membranes without analyzing salt in seawater Desalinated high-concentration seawater is used as a condensing agent for water vapor, which reduces material costs and energy consumption.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a low-energy seawater desalination system and method. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure stable water supply such as drinking water for coastal residents and supplementary water for industrial boilers. Currently, Seawater desalination equipment is increasingly being researched in the direction of low energy consumption equipment, in order to achieve the purpose of increasing production and reducing costs. [0003] Existing low-energy seawater desalination devices generally use solar energy evaporation methods, such as the "solar seawater desalination system" described in the invention patent w...
