PLANT FOR THE RENATURALIZATION OF WATER IN LAKES, SEAS AND OCEANS

摘要

The invention relates to a method and a plant for the renaturalization of deep polluted water in lakes, seas or oceans. According to the invention, the method consists in extracting polluted water as a consequence of priming a conduit by obtaining vacuum in a container attached to the said conduit, at whose base there is gas-free water which can be brought back to the sea by introducing atmospheric air into the container, through a turbo-expansion device coupled to an electric generator, at the same time there being eliminated the blow out effect by closing the valve of the vertical conduit and there being achieved the conversion of the compressed gas energy by expanding the same in a turbo-expansion device coupled to an electric generator, for compressing the air required for the combustion of sulphuretted hydrogen resulting in sulphuric acid, as well as the expansion of spent gases in a turbine, by actuating an electric generator. The claimed installation for carrying out the method comprises a vertical conduit (1) provided with a valve (2) integral with an enclosure (3) for storing non-polluted water (L) which is lifted through the conduit (1), due to the vacuum, the air (A), being eliminated by opening a valve (4) and using a vacuum pump (5) driven by a motor (6), the water (L) being removed by closing a valve (4) and opening another valve (7), the air introduced through the turbo-expansion device (8) actuating an electric generator (9), by using the liquid flowing through a valve (10) mounted at the base of the enclosure (3) and by using a pump (11) driven by a motor (12); before the valve (2), the conduit (1) has a side connection (13) provided with a valve (14) for closing the column with gas, which, under pressure condition is expanded through the turbo-expansion device (15), actuating a turbo-blower (16) for the compression of the air (A) required for the combustion of sulphuretted hydrogen (HS) in a burner (17), wherefrom gases are expanded into a turbine (18), actuating a generator (19) and finally being accumulated in a container (20).
