Ducted high-pressure high-concentration gas-liquid dissolver for renovation of water environment

Abstract

The invention relates to a ducted high-pressure high-concentration gas-liquid dissolver for the renovation of a water environment, which is a water quality protection and renovation device used for the deterioration of water quality caused by the consumption of in-water dissolved oxygen of an environmental water area. As shown in picture 1, the ducted high-pressure high-concentration gas-liquid dissolver mainly comprises a high-pressure submersible pump 1, a ducted high-pressure gas-liquid dissolution cabin 3, a high-pressure oxygen gas overflow and emission component 11 and a tail oxygen-enriched water ejector 15, wherein anoxic water in an anoxic water area is sucked in through the high-pressure submersible pump and is pressurized to move into the ducted high-pressure gas-liquid dissolution cabin; when passing through a duct of the high-pressure gas-liquid dissolution cabin, the anoxic water is mixed with oxygen gas emitted by the high-pressure oxygen gas overflow and emission pipe; the oxygen can be quickly dissolved in the duct of the high-pressure gas-liquid dissolution cabin at high pressure, thus forming oxygen-enriched water; and the oxygen-enriched water passes through the narrow tail ejector and is horizontally ejected to the anoxic water area of the same layer, thereby improving and renovating the water ecology. Meanwhile, due to the counterforce of the backward ejection of the oxygen-enriched water, the dissolver can be pushed to slowly advance, so that the water quality of more areas can be improved and renovated.

Description

technical field [0001] The invention relates to a channel-type high-pressure high-concentration gas-liquid dissolving device for water environment restoration, mainly for the protection and restoration measures adopted for the deterioration of water quality caused by the consumption of dissolved oxygen in the environmental waters, and belongs to the field of environmental protection. Water quality protection field. Background technique [0002] In recent years, environmental water pollution has become more and more serious in all countries in the world, and it is also becoming more and more serious in our country. In many enclosed and semi-enclosed waters such as reservoirs, lakes, and oceans, due to the aggravation of environmental pollution and the decomposition of organic matter, the dissolved oxygen in the waters is gradually consumed. Eventually, a large number of anoxic water areas will form at the bottom of some closed or semi-closed waters, which will lead to the de...

Problems solved by technology

Eventually, a large number of anoxic water areas will be formed at the bottom of some closed or semi-closed waters, which will lead to the deterioration of environmental water quality and affect the protection of the environment and ecology. If it is allowed to continue to develop, it may bring environmental and ecological disasters
