Aeration system for fishery breeding

Abstract

The invention relates to an aeration system for fishery breeding. The aeration system comprises breather pipes which comprise multiple horizontal air feed pipes vertically arranged in a culture pond, one end of each air feed pipe is communicated with an air outlet of a fan while the other end thereof is closed, multiple aeration pipes used for aeration are arranged on each air feed pipe and communicated with the air pipe, the external diameter of each aeration pipe increases gradually along the direction away from each fan, and all the aeration pipes are annular pipes made of carbon nanomaterials; an air valve is further arranged on each air feed pipe. The aeration system has the advantages that the independent air valves are arranged on the upper-lower breather pipes for the convenience of making aeration control on top and bottom sea water and different growth stages of shrimp, the diameter of aeration rings at the near ends of the air valves is small, the diameter of the aeration rings at the far ends of the air valves is large, and by the design, aeration resistance at the near ends is small to be beneficial to keeping air at the far ends under enough air pressure.

Description

technical field [0001] The invention relates to the field of breeding, in particular to an aeration system for fish farming. Background technique [0002] At present, in the field of fish farming where seawater is used to breed shrimp or fish, the aeration system adopted is generally a surface aeration machine, which lifts water into the air and scatters it into sprays to increase the contact area between water droplets and air to achieve the purpose of oxygenation. However, the oxygenation of the surface aerator has a certain effect on the oxygenation of the upper layer of seawater. This method has the disadvantage of slow oxygen mass transfer rate, resulting in poor oxygenation effect of the lower layer of seawater and high energy consumption. It is a relatively simple and extensive method. Oxygen way. [0003] Arranging mesopore aeration tubes in shrimp ponds is also a commonly used method of aeration and oxygenation. However, due to the large air bubbles produced by me...

AI Technical Summary

Problems solved by technology

However, the air pressure loss in the straight pipe aeration process will lead to insufficient exhaust at the far end of the aeration pipe. If the carbon nanometer aeration pipe is arranged too long, the material cost will be high

When the long and straight carbon nanometer aeration tubes are placed horizontally on the bottom of the pool, pond mud will also accumulate and cause the aeration tubes to be blocked, and the clear ponds are easy to break when recycled, and it is not easy to use them on a large scale
