Seawater desalination system

Abstract

The present invention relates to a seawater desalination system, comprising: an evaporation mechanism and a condensation mechanism communicated with the evaporation mechanism. The evaporation mechanism comprises two conductors spaced at intervals, spaced and side-by side thermoelectric cooling sheets and thermo power wafers being installed at the intervals of two conductors. Thermoelectric sheet has a cold face and a hot face, which combined with the top and bottom faces of the thermo power chip is fitted in with the two conductors. The temperature induced by the cold face and the hot face of the thermoelectric cooling sheets is transmitted to thermo power chip. By temperature difference of thermoelectric cooling sheets, current is generated by the thermo power chip. The thermo power chip is connected to a condenser which transmits and stores the current to provide the thermoelectric cooling sheets with current. The invention generates regeneration energy and reduces heat discharging capacity by the temperature difference of thermoelectric cooling sheets in the process of seawater desalination.

Description

technical field [0001] The present invention relates to a seawater desalination system, in particular to a structure for generating renewable energy during the desalination process. Background technique [0002] Due to the large increase in population and the improvement of life, the demand for fresh water is constantly increasing. On the one hand, the impact of the greenhouse effect on the earth is becoming more and more significant, so human beings are already facing the problem of fresh water supply. Desalination of seawater is an effective way to solve the problem of freshwater supply. Since 70% of the earth is covered by seawater, the supply of seawater is inexhaustible for human beings. [0003] Most of the existing seawater desalination uses the principle of distillation to obtain fresh water. Its structure is simple, and the amount of water produced for desalination is large, but the energy consumption and pollution are also relatively large. It is mainly burned by ...

Problems solved by technology

[0003] Most of the existing seawater desalination uses the principle of distillation to obtain fresh water. Its structure is simple, and the amount of water produced for desalination is large, but the energy consumption and pollution are also relatively large. It is mainly burned by an incinerator to heat the seawater to the boiling point and vaporize it. The produced water vapor is guided to a condensation chamber through a steam pipe, and fresh water is condensed through the condensation chamber. The fuel required by the incinerator is heavy oil, which causes great pollution to the environment after burning; in addition, a large amount of Seawater is heated from normal temperature to boiling point in order to generate water vapor, so it requires a lot of energy; there is also a seawater desalination device based on electric energy, which uses a large amount of electric energy to heat seawater to boiling point to vaporize, and obtain fresh water through condensation, so It also requires a lot of energy

[0004] Due to the rising awareness of environmental protection, coupled with the shortage of coal and oil and the difficulty of mining, the use of electric energy continues to increase, so we often face the crisis of power outages and power outages, and also face the crisis of producing a large amount of carbon dioxide due to heat emissions. Although kinetic energy generation devices using solar and wind power have been developed, the cost of the equipment is extremely expensive, and is affected by natural uncertain factors such as terrain, weather, sunlight angle, wind direction, etc., resulting in poor stability in obtaining kinetic energy , the cost is not low, so it is necessary to study and improve it.
