Description

[Detailed Description of the Invention] The present invention relates to an ultrasonic shower that is used, for example, to atomize seawater to make it easier to evaporate when producing fresh water from seawater.

For example, in the past, to atomize seawater, a rock-like object was placed with a large surface area, and the seawater was poured over it, causing it to flow down like a waterfall and evaporate. According to this method, uniform atomization could not be achieved and efficient evaporation could not be expected.

The present invention proposes an ultrasonic shower consisting of a cylindrical body with one side open, a slit plate that closes the opening, and a horn disposed inside the cylindrical body opposite to the slit plate. According to this configuration, seawater can be sprayed onto the slit plate by ultrasonic waves from the horn, uniformly atomized, and injected, and efficient evaporation can be expected.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1 is a concave path formed by an outer box 2 and an inner box 3, including a descending route 1A and a descending route 1A.
It consists of a lateral path 1B that communicates with the lower part of the lower lateral path 1B, and an ascending path 1C that communicates with the terminal end of this lower lateral path 1B.
Reference numeral 4 denotes an ultrasonic shower installed in the upper part of the descending path 1A, which includes a cylindrical body 5 with only the lower part open, a wire mesh-like slit plate 6 that closes the lower part opening, and is arranged downward in the cylindrical body 5. and a horn 8 supported on the side of the cylindrical body 5 by a support rod 7, and a seawater supply pipe 9 communicates with the upper part of the cylindrical body 5. This seawater supply pipe 9 pumps up seawater 11 with a pump 12 and passes through a heater 10 . 13 is a controller connected to the horn 8. The lower end of the descending route 1A is formed in a seawater receiver 14, and this seawater receiver 1
4 is connected to a seawater discharge pipe 16 having a pump 15. The lower surface of the horizontal path 1B is the upward path 1C.
It is formed into an inclined surface 17 whose side is the lower side. The lower end of the ascending path 1C is formed in a product water receiver 18, and a product water outlet pipe 20 having a pump 19 communicates with the product water receiver 18. A fresh water injection nozzle 21 is disposed at the upper part of the ascending path 1C, and a fresh water supply pipe 23 that is branched from the produced water take-out pipe 20 and has a pump 22 in the middle is connected to this fresh water injection nozzle 21. The descending route 1
A suction port 27 is provided at the upper part of the ascending path 1C to which a suction pipe 26 having a pump 25 communicates.

Next, the water production effect will be explained. First, the pump 25 is operated to create a vacuum in the concave path 1. In this state, the seawater 11 pumped up by the pump 15 is heated to the heater 10.
For example, heat to 80℃ and use an ultrasonic shower 4
is supplied into the cylindrical body 5 of. The seawater 11 filling the cylindrical body 5 is blown onto the slit plate 6 by ultrasonic waves from the horn 8, and is sprayed downward in the form of mist. At this time, the concave path 1 is evacuated (depressurized), so that the mist is easily evaporated. The injected mist consists of a heavy mist (a) containing salt and a light mist (fresh water vapor) (b) without salt. Of these, the heavy mist (a) falls along the descending path 1A and enters the seawater receiver. It was accepted by 14. As described above, an air current is generated in the concave path 1 by the operation of the fan 24, and therefore light mist enters the ascending path 1C through the horizontal path 1D and ascends the ascending path 1C. I'll go.
Fresh water injection nozzle 2 for the rising light mist
A high-pressure shower of fresh water is sprayed from 1, whereby the light mist is cooled and turned into water droplets, which become product water 28 and are collected in the product water receiver 18.

According to the ultrasonic shower of the present invention described above,
Since the seawater inside the cylindrical body is sprayed onto the slit plate by ultrasonic waves from the horn, it can be uniformly atomized and sprayed through the slit plate, and efficient evaporation can be expected.
