Description
Technical Field
The invention relates to a water body oxygenation system, in particular to a system which can push the whole water body by an air pump with low energy consumption when large-area and deep water body oxygenation is needed in the aquatic organism culture and transportation and the odor river water treatment process, so that the whole water body can be ventilated and oxygenated.
Background
At present, the known methods for increasing oxygen in water bodies can be roughly divided into four categories.
1) The air pump and the air stone or the air disk are directly thrown into the water, and the air bubbles are continuously released in the water, so that the method is generally only suitable for small-area water bodies. 2) The propeller and the water groveling vehicle are used for increasing oxygen, which is generally used for large-area aquaculture of fish ponds, reservoirs and the like, but only can stir the surface layer of the water body. 3) The water pump type oxygenation is to utilize a water pump to lift water and then fall back. 4) The patents (patent numbers: ZL201120192020.5 and ZL201010177387. X) obtained in 2011 by the inventor are subjected to air explosion oxygen increasing, and the oxygen increasing mode is relatively suitable for increasing oxygen in large and deep water bodies.
Disclosure of Invention
It is first to be understood what is effective oxygenation of the water body, as it is now generally accepted that oxygenation is the addition of oxygen to the water. However, according to the henry principle, the water-soluble gas has a saturation, and the water is always in the saturated state of the dissolved gas under the condition that the air pressure, the salinity and the water temperature of the water are not changed in a certain period of time, and the total amount of the gas capable of being dissolved in the saturated state comprises the mixed total amount of each gas capable of being dissolved in the water. Generally, the total amount of oxygen and carbon dioxide contained therein is in ascending and descending order. To dissolve more of a gas, the first step is to release the gas dissolved in the original water so that the gas can be saturated. The so-called aeration is common at present, and basically only a larger amount of air and the only air in water are mixed once, because the oxygen content of the large amount of air is fixed at 21%. The oxygen value of water is usually reduced after the organisms in the water consume the oxygen, and if the mixing is successful, the oxygen value is increased, which is known as oxygenation. According to the theory, I draw a conclusion that the oxygen increasing of the water body is proportional to the degassing capacity of the water body, and the gas in the water to be removed needs to be changed according to three major factors of the Henry principle, wherein I choose to change the pressure. The most effective method for changing the pressure of the gas in the water is to generate a relative movement speed between the water and the gas, so that the water can flow in the air (for example, the existing method is a water pump type, a flying water type, a climbing water type and the like), and the gas can also slide in the water (for example, the gas pump releases bubbles in the water through air stones). And I think that the larger the speed of the relative movement, the larger the low-pressure area generated in the water is like the tornado, so that the more the gas is removed from the water, the larger the amount of air mixed into the water is, and the better the oxygenation effect is.
The inventor of the invention obtains patents (patent numbers: ZL201120192020.5 and ZL201010177387. x) in 2011 by air explosion oxygen increasing, and the biggest problem is that an air compressor does not directly fill the ballast with the shunted air bubbles, so the pressure of the ballast cannot rise within a certain time, namely, the air collector cannot be closed in the time, so the system can be established only by using a relatively quick air compressor.

The air guide opening in the upper part of the ballast chamber is at a clearance distance from the upper wall of the air collector, and air bubbles can enter the air guide opening through this position to reach the upper part of the ballast chamber.

The air gate is a soft cushion which can be concave-convex up and down, the area of the air gate covers the air discharge port and the air guide port of the pressure detecting cabin, and the pressure detecting cabin can be isolated into an upper cabin body and a lower cabin body, but the two cabin bodies can transmit pressure due to the soft cushion.
