An ultrasonic-assisted solar desalination device based on thermovoltaic coupling technology

Abstract

The invention discloses an ultrasonic assisted solar seawater desalination device based on a thermal coupling technology. The ultrasonic assisted solar seawater desalination device mainly comprises a solar photovoltaic cell, an evaporation and condensation integrated tank, a medium-high temperature solar heat collecting tube, a tank-type heat exchanger, an ultrasonic atomizer, wherein solar radiation energy is collected through the medium-high temperature solar heat collecting tube to directly seawater in an evaporation cabin, so that the generated steam flows into the tank-type heat exchanger to form fresh water; electric heating can be started in rainy days or at night; the power is from electric energy which is stored in a storage battery by the solar photovoltaic panel; meanwhile, assisted evaporation is carried out employing the ultrasonic atomizer; and scale formation is prevented. In the manner, a traditional energy source is not consumed. The ultrasonic assisted solar seawater desalination device has the advantages of high water production rate, small size, simple arrangement, convenient use, environment friendliness, low price and the like, can be suitable for fresh water shortage areas such as island residents, island garrison, ocean vessels, offshore drilling platforms, island tourist areas and coastal water shortage cities.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization and seawater desalination, and in particular relates to an ultrasonic-assisted solar seawater desalination device based on thermovoltaic coupling technology. Background technique [0002] In recent years, under the guiding ideology of building a maritime power, the speed of developing the marine economy and protecting the marine ecological environment has been significantly accelerated, especially in island areas. However, one of the important reasons affecting its faster development is the lack of fresh water resources. and industrial development have brought many problems. Since the island is far away from the mainland, the current solution to the problem of fresh water shortage requires a huge amount of money to transport fresh water to the island, which is too expensive. The introduction of seawater desalination equipment on the island can effectively alleviate the problem of ...

Since the island is far away from the mainland, the current solution to the problem of fresh water shortage requires a huge amount of money to transport fresh water to the island, which is too expensive, and the introduction of seawater desalination equipment on the island can effectively alleviate the problem of fresh water shortage

At present, the two relatively mature methods of seawater desalination technology are reverse osmosis and distillation. Reverse osmosis requires electricity to drive a high-pressure pump to make water molecules in seawater enter the other side through the osmotic membrane to play a role in desalination. Obviously, in the absence of electricity Or it is difficult to popularize and use on islands where power is lacking
