Floating solar seawater desalination device

Abstract

The invention discloses a floating solar seawater desalination device, which comprises a salt water tank and a fresh water tank; an evaporator is arranged on the top of the salt water tank, the sidewall of the salt water tank is provided with a salt water outlet, the salt water outlet is connected to the evaporator through a salt water pipe, the salt water tank is connected to the evaporator through a salt water outlet pipe, and the evaporator is connected to a condenser through a return gas pipe and a vapor pipe; a solar photovoltaic panel is arranged on the top of the fresh water tank, the fresh water tank is connected to the condenser through a fresh water pipe and a fresh water motor is arranged at the joint, a power supply and control device is arranged on the sidewall of the fresh water tank, and the power supply and control device is respectively connected to the condenser, the fresh water motor, the evaporator and the solar photovoltaic panel. The floating solar seawater desalination device disclosed by the invention uses a condensing panel to gather scattered sunlight, uses an evaporating plate in cooperation with trace water supply to rapidly heat seawater to evaporate, uses floating to break through the bottleneck of wide application on the sea, and uses the low temperature of seawater at certain depth to rapidly condense vapor.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination equipment, in particular to a floating solar seawater desalination device. Background technique [0002] my country has a vast sea area and is in the process of vigorously developing the marine economy. One of the major factors restricting the development of the marine economy is the lack of fresh water. Many islands and ocean-going platforms must be replenished with fresh water by boat regularly so that the stationed personnel can live normally. And plant some vegetables to effectively improve the living standards of the stationed personnel. [0003] At present, there are two main types of technologies for obtaining fresh water from seawater: (1) Osmotic membrane—this method is the development direction of seawater desalination in the future, but its technical requirements are high, and it is still difficult to be widely used in the production of drinking fresh water. The cost of de...

[0003] At present, there are two main types of technologies for obtaining fresh water from seawater: (1) Osmotic membrane—this method is the development direction of seawater desalination in the future, but its technical requirements are high, and it is still difficult to be widely used in the production of drinking fresh water, and it is used The cost of desalination of seawater by osmotic membrane is also relatively high; (2) Evaporation and condensation—this method is the most widely used, but the efficiency of seawater desalination is relatively low. The effect of factory waste heat to achieve low-carbon environmental protection

[0004] my country has a long coastline, and coastal areas are very suitable for the development of saline-alkali industry. Evaporating seawater can provide primary raw materials for enterprises, but seawater evaporation is a very energy-consuming and time-consuming process. How to extract high-concentration brine efficiently and economically is an urgent need research topic
