Pipeline compound aerating device

Abstract

The invention relates to a pipeline compound aerating device. A water conveying pipe is horizontally arranged at the bottom of a pool, wherein a starting end is provided with a water inlet, the tail end of the water conveying pipe is communicated with the lower end of an inner pipe, the outer side of the inner pipe is provided with a separating pipe, the bottom of the separating pipe is higher than the bottom of the inner pipe, the outer side of the separating pipe is provided with an outer pipe, the bottom of the outer pipe is in sealing connection with the side wall of the inner pipe, the lower part in the inner pipe, and the lower part of an annular space between the outer pipe and the separating pipe are provided with aerating heads, and the aerating heads are connected with an air pump. Through secondary pipeline aeration, the pipeline compound aerating device is capable of improving a dissolved oxygen value in water and volatilizing hazardous substances, such as volatile organicmatters, NH3 and H2S, in the water, and enabling the bottom layer water in the pool to overflow and mix with a water surface by an overflowing pipe through the aeration, under the photosynthesis of sunshine, absorbing the hazardous substances in the water by algae, releasing oxygen, and improving the dissolved oxygen value in the water again; and efficiently oxygenating, evaporating and oxidizingthe hazardous substances deposited on the bottom layer of a water area, and guaranteeing the good water quality.

Description

technical field [0001] The invention relates to an aeration device, in particular to a pipeline multiple aeration device. Background technique [0002] The sedimentation of fish dung and residual bait is the biggest problem in farming, and it is also the biggest headache for farmers. See image 3 , 24-hour monitoring of the oxygen content of the water quality of the aquaculture pond, it is found that the oxygen content of the water layer above 0-0.5 meters is 6.3mg / L, while the oxygen content of the water layer below 1.5 meters is only 0.8mg / L, which shows that the oxygen content in the pond culture The residual bait excrement settles on the bottom layer, and when the organic matter does not get enough oxygen to oxidize, the sediment undergoes anaerobic fermentation and releases a large amount of organic matter and NH 3 and H 2 Harmful substances such as S are dissolved in the bottom water to make the oxygen content ultra-low, which affects aquaculture, and will cause heav...

Problems solved by technology

[0004] Aeration and oxygenation in the prior art, see figure 1 , aeration can lift the water but not all the lower water contains organic matter, NH 3 and H 2 Harmful substances such as S are mixed with the upper water

Therefore, the existing aeration and oxygenation devices are subject to certain restrictions in use.
