Device for oxygenation by pressurizing and spraying bottom water in pond

Abstract

The invention discloses a device for oxygenation by pressurizing and spraying bottom water in a pond. The device comprises a high pressure water pump and a plurality of water spray branch pipes erected above the water surface of the pond. A water inlet of the high pressure water pump is connected with a water inlet pipe, the water inlet pipe stretches into the bottom water in the pond, a water outlet of the high pressure water pump is connected with a main water conveying pipe, the main water conveying pipe is connected with the water spray branch pipes, and small holes for spraying water are formed in each water spray branch pipe. Through the device, on the one hand, oxygen-deficient water at the bottom layer of the pond is pumped to the water surface through the high pressure water pump, and thus vertical circular flow of water in the pond can be accelerated; on the other hand, the oxygen-deficient water is sprayed out of the small holes in the water spray branch pipes, formed water mist or spray can further expand the area of contact between water and air, the water mist or spray falls into the water after being oxygenated through friction with air, and thus the oxygenation effect is greatly improved.

Description

technical field [0001] The invention relates to an oxygenation device, in particular to a pressurized water spraying oxygenation device utilizing the bottom water of a pond. Background technique [0002] The aerator is a kind of machine that is often used in the aquaculture industry, among which the impeller aerator is the most widely used one in recent years. The impeller type aerator floats it on the water surface through the buoyancy of multiple floating balls, the impeller only rotates on the water surface, only a small amount of air is stirred into the water, the oxygenation effect is only about 50 cm deep, and the bottom water is always dissolved oxygen It is not conducive to the oxidative decomposition of harmful substances such as organic matter and nitrite deposited at the bottom of the water body, resulting in the enrichment of harmful substances such as sulfide, nitrite and ammonia nitrogen in the bottom water. To this end, my country's aquatic industry is vigoro...

AI Technical Summary

Problems solved by technology

For this reason, my country's aquatic industry is vigorously advocating and promoting underwater aeration and oxygenation technology to achieve effective bottom oxygenation. Oxygen time is short, water body flow is less, so the range of water body for effective aeration and oxygenation is small, which leads to unsatisfactory promotion effect of this technology
