最高液面を示す。One aspect of a conventional reverse osmosis desalination apparatus will be described with reference to FIG. The conventional reverse osmosis desalination apparatus comprises a high pressure pump 1, a reverse osmosis membrane module 2 and a desalination water tank 3, raw water is supplied to the reverse osmosis membrane module 2 by the high pressure pump 1, and desalination water is supplied through a pipe 6. The high-pressure pump 1 and the reverse osmosis membrane module 2 were arranged to be stored in the demineralized water tank 3 at approximately the same level. This is because when the operation of the apparatus is stopped, the pressure on the demineralized water side causes vacuum bubble generation due to the positive osmotic pressure (natural osmotic pressure), which causes membrane deterioration. In the figure, 3'represents the bottom liquid level and 3 "the highest liquid level.

問題点があった。If the high-pressure pump, the reverse osmosis membrane module and the desalination water tank like the above-mentioned conventional equipment are installed on the same level surface, the installation area becomes wide, and the connecting pipe between the high-pressure pump and the reverse osmosis membrane module rises and rises. Since a portion is generated, there is a problem that raw water is accumulated in the pipe and the pipe is easily corroded.
本考案は上記技術水準に鑑み、設置面積が狭まくてす
み、かつ原水の溜りによる配管の腐蝕などの心配のない
逆浸透法脱塩装置を提供しようとするものである。In view of the above-mentioned state of the art, the present invention aims to provide a reverse osmosis desalination apparatus which has a small installation area and is free from fear of corrosion of pipes due to accumulation of raw water.

ることを特徴とする逆浸透法脱塩装置である。The present invention is a desalination device comprising a high-pressure pump, a reverse osmosis membrane module, and a desalination water tank. The reverse osmosis membrane module is installed above the high-pressure pump, and one room divided by a baffle always stores a certain level of desalination water. The reverse osmosis desalination apparatus is characterized in that the desalination water tank configured as described above is installed at the same level position as the high-pressure pump.

る。As in the device of the present invention, by arranging the high-pressure pump and the reverse osmosis membrane module vertically, not only the space for the entire arrangement can be reduced, but also the raw water in the pipe is not accumulated and the pitting corrosion of the pipe is prevented. be able to. By doing so, the height of the reverse osmosis membrane module becomes high, and when the operation is stopped, bubbles may be generated in the reverse osmosis membrane module due to vacuum due to the osmotic pressure, and the performance of the membrane of the reverse osmosis membrane module may be deteriorated. However, this problem is that the inside of the tank is divided into two by a baffle, and one room has a structure such that desalinated water is always stored, and the desalinated water piping from the reverse osmosis membrane module is stored. The device of the present invention has been solved by immersing it in demineralized water.
