[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable seawater desalination apparatus using a reverse osmosis membrane.

[0002]

[Technical background of the invention] According to the rules of the ship's lifesaving equipment regulated by the Ministry of Transport, the required amount of rescue food, 1.5 liters of drinking water per person, drinking cup, emergency medical equipment as a load on the life raft It is obligatory to equip a complete set with the required amount of seasicks, seasickness bags and the required amount of warming equipment. However, with regard to drinking water, it is stated that 0.5 liters of drinking water per capita can be replaced by a seawater desalination device deemed appropriate by the Public Administration.

[0003]

2. Description of the Related Art According to the Marine Equipment Inspection Association, a life raft maker in Japan has not developed a seawater desalination device that the Pipe and Marine Agency deems appropriate, and a manual desalination device made in the United States has not been developed. It is commercially available. The specifications of this hand-made water generator are as follows: Water production amount: 0.24 liters / 13 minutes ± 15% Weight: 1.1 kg Height: 13 cm Length: 20 cm Width: 6 cm Salt removal rate: 98.4% (average) , 95.3% (minimum) Average number of hand presses: 40 times / minute, the price per car is expensive, and the cost for equipment for each car is high, and the equipment cost is high. In addition, with the performance of 0.24 liters / 13 minutes ± 15% seawater desalination with a manual pump action of 40 times / min, it takes 26 minutes to produce 0.5 liters of water, and the labor is excessive. There is also the irrationality of mounting a device weighing 1.1 kg instead of 0.5 kg of water, which is 1/3 of 1.5 liters per person.

An object of the present invention is to provide a desalination apparatus for seawater which uses a gas cylinder of a container of 100 cc or less which is not regulated by the High Pressure Gas Control Law and requires no labor.

[0005]

SUMMARY OF THE INVENTION In order to solve the problems of the prior art, the construction of the present invention is to provide a filter chamber through a partition having a small hole at the lower part of a grippable seawater storage cylinder having a pressure resistance. A reverse osmosis membrane filter is exchangeably housed in the chamber, while a lid that can be screwed upside down is detachably screwed into the upper opening of the seawater storage cylinder, and a ventilation pipe equipped with a cock is provided on this lid. Provided,
The vent pipe is provided with a holder having a stopper for opening a cartridge type gas cylinder having a capacity of 100 cc or less.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a vertical sectional front view of an unused state, that is, a portable state, and FIG. 2 is a vertical sectional front view of a used state.

Reference numeral 1 denotes a seawater storage cylinder having a pressure resistance and a size that can be gripped, and a filtration chamber 4 is provided below the seawater storage cylinder 1 through a partition 3 having a small hole 2. Provide. A reverse osmosis membrane filter 5 is exchangeably accommodated in the filtration chamber 4. In the figure, 6 is a fresh water supply pipe, and 7 is a cock. On the other hand, a lid 8 that can be screwed up and down is detachably and airtightly screwed into the upper opening of the seawater storage cylinder 1, and a ventilation pipe 11 having a cock 9 and a pressure reducing valve 10 is provided on the lid 8. The vent pipe 11 is provided with a holder 14 having a stopper 13 for a cartridge type gas cylinder 12 having a capacity of 100 cc or less. The lid 8 is formed by joining two plate-shaped lid members 8a back to back so that they can be screwed together. In addition, a bottom cover 15 having a dish-like structure is screwed to the attachment / detachment itself at the lower opening of the filtration chamber 4 so that the reverse osmosis membrane filter 5 can be replaced.

[0008]

Next, the operation of the embodiment will be described.
The lid 8 is removed from the posture shown in FIG. 1, and about 80 to 90% capacity, that is, 100 cc or less of seawater is stored in the seawater storage cylinder 1.
The top and bottom of the lid 8 are exchanged and screwed to the seawater storage cylinder 1 while maintaining airtightness. Next, the cock 9 is opened through the stopper 13 and the pressure reducing valve 10, and high-pressure gas is supplied into the seawater storage cylinder 1 to pressurize the seawater. The seawater is desalinated by the high-pressure gas through the reverse osmosis membrane filter 5 and is continuously recovered from the freshwater supply pipe 6. When about 90% of the seawater is desalinated, the cock 7 is closed leaving the seawater with a high salt concentration. At the time of refilling the seawater or at the end of desalination of the seawater, the cock 9 is closed and the gas pressure is stopped, and then the cock 7 is opened. The inside of the seawater storage cylinder 1 is returned to normal pressure, and the lid 8 is opened.

[0009]

According to the configuration of the present invention as described above, the following effects can be obtained. (A) Since seawater is desalinated by using a high-pressure gas pressure and by a reverse osmosis membrane means, desalination of seawater is automatically performed by a manual pump means without labor compared with the prior art. I can do it. Further, since a gas cylinder of 100 cc or less is used, it is not subject to the regulations of the High Pressure Gas Control Law, it is convenient to handle, and it can be reduced in size and weight, so that the loading weight is not pressed. (B) Since the gas cylinder is attached to the lid that can be screwed up and down, the cylinder can be stored in the seawater storage cylinder as shown in FIG.
Further, compactness can be achieved.
