The invention relates to the water supply of agriculture and can be used to obtain salt ore by expeditions engaged in the development and study of deserts, as well as marine and oceanic spaces.

The purpose of the invention is to increase the efficiency of the device by preventing pollution of the environment and the beneficial use of salts contained in water.

The drawing shows the proposed device, a longitudinal section.

A device for desalination of saline water includes a heat exchange pipe 1, the upper part of which is supplied by a flange 2 with a gasket 3, and the lower one contains an inlet 4 for introducing the original saline water and a chute 5 located at the bottom level and descending the heat exchange pipe 1, moreover, the chute 5 is connected to the drain pipe 6 for draining condensate from the device. A cavity of the evaporation chamber 7 is located around the heat exchange tube 1, which is equipped with a reservoir 8, which is filled with porous filler 9, for example, a soil of light mechanical composition and is installed above the stops 10 fixed to the bottom of the device. The outer lateral surface of the container 8 forms the main part of the device body and contains a vibrator 11 for peeling salts, ten5

Ziometer 12 for controlling the humidity of porous aggregate 9 and radiation plates 13 for absorbing solar radiation. Internal, bordering the evaporation chamber 7, the lateral surface and the bottom of the container 8 are made perforated, for example, in the form of a mesh frame 14 of stainless material. The upper part of the container 8 comprises a flat ring 15c with a sealing gasket 16 fixed flush to the inner side of the side surface of the device and connected by stiffeners 17 with the flange 2 of the heat exchanger tube 1 The capacity 8 and the heat exchanger tube 1 with the evaporation chamber 7 located between them are sealed by means of locking elements 18 and gaskets 3 and 16 of a hollow cover 19, having the form of a flat cylindrical container and provided with a hole 20 for inlet coaxial with the heat exchanging pipe 1 located in its bottom and the original saline water, above which a valve 21 is installed in a threaded sleeve arranged in the lid 19 to regulate the flow of water to the lid 19. For supplying water to the tank 8 with porous floor filler 9, the lid 19 has a water distributor in the form of circumferential and tubes 22 equidistant from each other, the lower part of which is perforated and placed in porous filler 9 of container 8, and the upper part 5 1

placed above the bottom of the lid 19. For storing the salts under the tank 8 in the slots of the device body between the lugs 10 there are salt pans 23 with grips 24 made with the possibility of extending out of the slots, for example, in the shape of the rectangular sector with an imaginary angle at the top of 90k and fitted with to prevent cold leakage by a sealing gasket 25 located at the seat of the pallet 23 against the outside of the side surface of the device. For the same purpose, the bottom of the device has thermal insulation 26. The dimensions of the device can be of any given size, for example, from mobile bucket size to stationary volumes up to 4000 m3 and more.

The device works as follows.

Open the inlet valve 21 at a given flow rate. As a result, the source mineralized water, which comes with a source of cold, enters the heat exchange pipe 1 through the inlet pipe 4, cools it and then goes through the opening 20 into the hollow cover 19. Here the water heats up and after filling the cover 19 to the upper edge of the pipes 22 in the heated form through the perforated part of the tubes 22 enters the porous aggregate 9 in the tank 8 and saturates it to a moisture content higher than the moisture content of the capillary rupture, but no more than the smallest moisture capacity of the porous filler 9. - existed by means of a tensiometer 12. Moisture entering the porous filler 8 moves capillary to the evaporation surface, which is the mesh frame 14, forming the bottom and inner walls of the vessel 8. When it reaches, the moisture evaporates, which is also promoted by heating the porous filler 9 by means of radiation plates 13 located on the outer side surface of the vessel 8. In this case, salts precipitate and are deposited on the mesh frame 14. The vapor-air mixture formed during evaporation of moisture, in accordance with the second m law of thermodynamics moves in the vaporization chamber 7 to the heat of decreasing and reaching the heat exchange pipe 1, kondensiruet106

with on its surface. The condensate formed flows into the drying heat exchanger tube 1 and the chute 5 located at the bottom of the device, from which the device is discharged out of the device through the pipe 6. The salt from the ore as it accumulates is removed from the mesh frame 14 by incorporating the vibrator 11 into the inlet pallets 23, located under the tank 8 in the slots of the device case between the stops 10. The salt pans 23, after filling with salt ore, are pulled out of the device case by means of the clamps 24, are emptied and again are pushed into the device. The resulting salt ore during desalination can be used as raw material in the chemical industry. The prevention of cold and heat leaks in the device is achieved by tightly fitting the hollow cover 19 by means of locking elements 18 to the gaskets 3 and 16 located respectively on the flange 2 of the heat exchange tube 1 and the flat ring 15 with which the upper outer side surface of the device is provided. For the same purpose, salt receptacles 23 are hermetically sealed by means of a sealing gasket 25 to the body of the device, and in the bottom of the device there is thermal insulation protection 26.

In the proposed device for intensifying the evaporation of saline water, radiation plates 13 are provided, by means of which solar energy is absorbed and the outer side surface of the container 8 made of heat-conducting material, for example aluminum, is heated, followed by transferring thermal energy contained in the container 8g to the porous filler - soil. Another technique that promotes increased evaporation of mineralized moisture is its preheating in the hollow cover 19, the saw-like upper surface of which allows solar energy to be captured at any angle from the sun's rays. For the same purpose, the floor cover 19 has the form of a flattened flat container (a large surface with a small volume of water in the vessel), which increases the contact area of water with the heat-absorbing surface of the cover and.

rapid heating of moisture to high temperatures.
