Embodiment Construction

[0007] The present invention will be further described below in conjunction with accompanying drawing:

[0008] See accompanying drawing 1, seawater lift pump (1) is lifted and controlled by seawater. The valve (2) is connected with the decompression evaporation chamber (6), and the seawater lifting control valve (2) is opened except when pumping seawater, and is generally closed to ensure the airtightness in the decompression evaporation chamber (6). , 4-solar heat absorption pipe (4) is airtightly connected with decompression evaporation chamber (6), and seawater heating circulation pump (5) is connected in series therebetween, and it is between solar heat absorption pipe (4) and decompression evaporation chamber (6) Continuously beat circulation, improve the temperature of seawater in the decompression evaporation chamber (6). The decompression evaporation chamber (6) is connected with the A-way air-water separation tank (12-1), the B-way air-water separation tank (12-2), ...

Abstract

The present invention discloses one circulating energy converter for heating water with solar energy. The circulating energy converter includes one calandria with coating capable of absorbing solar heat and insulating heat, one evaporator connected hermetically to the calandria, one lift pump in between, and one temperature control system to raise the temperature of sea water to 50-85 deg.c for boiling at relatively low pressure. It has low power consumption and capacity of producing fresh water continuously. It may be applied in places with lack of fresh water, such as island, pelagic ship, etc.

Description

1. Technical field: [0001] The solar-powered seawater desalination device of the invention relates to the technical field of seawater desalination, and is mainly used in coastal water-deficient areas (such as coastal islands) or ships sailing in the ocean. Background technique: [0002] At present, seawater desalination methods are roughly divided into three categories. One is the traditional distillation method, which is to collect the desalinated distilled water after boiling seawater. Because this method consumes a lot of energy, it is generally not used. The second is the vacuum distillation method. The existing example is to use the steam waste heat of the thermal power plant to heat the seawater, and then reduce the pressure in a closed container to reduce the boiling point of the seawater to obtain distilled water. The defect of this method is that the conditions are specific, that is, it needs There are thermal power plants to provide heat, but in water-scarce areas,...
