Abstract

The invention relates to a power plant for desalinating seawater using solar energy and improves the desalination plant performance. In the solar desalination plant, which contains a vapor-coated evaporation chamber, a condenser, a chimney and a condensate trap, a condenser is installed under the exhaust pipe for rotation and is made of two spherical elements, the upper of which is adjacent to the transparent coating and the lower one to the condensate trap, and it is equipped with heat pipes fixed on it with upper ends and vertical blades, while the condensate collection trap is made in the form of an annular chamber located between the bottom and the bottom spherical element. Placing the upper ends of the tubes in the condensation chamber, installing the condenser with the possibility of rotation, and the presence of blades make it possible to improve heat transfer from the lower ends of the heat pipes due to the rotation of the condenser under the influence of air drawn through the exhaust pipe, i.e. without energy. 3 il.

Description

The invention relates to power plants designed to desalinate seawater, in particular to floating desalination plants using solar energy, and can be used in areas with existing freshwater deficiency.

The aim of the invention is to increase the productivity of desalination plant.

Figure 1 shows the desalination plant, a longitudinal section; FIG. 2 is a view A in FIG. fig.Z - section BB in fi 1.

The solar watermaker contains an evaporation chamber 1 having

translucent fiberglass coating 2 and bottom 3, permeable to water, exhaust pipe 4, equipped with a plastic jacket 5, an annular condensate collector 6 located above the water level in the reservoir 7, a condensation chamber 8 formed by spherical upper 9 and lower 10 elements, heat pipes 11, vertical blades 12, installed tangentially.

Each heat pipe 11 consists of several successively connected pipes with a liquid energy carrier at the lower end. As an energy carrier heat pipes can

The lower ends of the pipes 11 are inserted from the bottom 3, and the upper ones are hermetically mounted into the element 10, made of a material with high thermal conductivity, for example copper or aluminum. 1 A spherical element 10 is mounted on a rotating support 13 coaxially with the pipe 4 so that its edges are located above the condensate container 6. Camera 1 is additionally connected to the atmosphere by side air intakes 14 with an anti-fungal fungus 15. the pipe 4 is connected to the chamber 1, the upper spherical element 9, which protects the condenser from being heated by the sun's rays.

The surveyor works as follows.

The desalinated seawater enters the evaporation chamber 1 through the permeable bottom 3. Once in the chamber, the water is heated by infrared radiation from the sun, penetrating through the coating 2. From the rise in temperature and HIGH thrust through pipe A formed by the air inlets 14, the chamber 1 s Atmosphere, the air transported by the air gaps moves from the periphery to the center of the center and comes into contact with the upper ends of the heat pipes 11 and the cooled top element 9 and the blades 12. The water vapor condenses: Cam 12, pipe 11, element 10 in condensate collector 6, and air goes into pipe A, creating a rotating moment on element 9 which rotates element 9, which causes it to rotate in support 13 together with heat pipes 11, which causes the necessary. water circulation at the lower ends of heat pipes immersed in water.

From the condensate collector 6 water flows by gravity through a pipeline 16

for example, in floating storage cistern)) s (not pokachany).

Performing each heat pipe 11 of several heat pipes connected in series allows heat exchange from considerable depths, where the water is colder, and, with a great deal, to obtain a significant decrease in the temperature of the upper ends of these pipes, i.e. to create a garden of sufficiently high performance and with increased efficiency.

The technical and economic effect of the proposed device is to increase productivity. In addition, the desalination plant does not require an auto energy source for pumping desalinated water and the desalination plant, which reduces operating costs, and, consequently, reduces the cost of desalinated water, increases the cost-effectiveness of the desalination plant.
