Microporous aerating oxygenation device for oxygenating water body

Abstract

The invention relates to a microporous aerating oxygenation device for oxygenating a water body. The microporous aerating oxygenation device comprises an air blower, an air delivery pipe and an oxygenating disc, wherein the air delivery pipe is connected with an air outlet of the air blower, the oxygenating disc is shaped like a disc rising gradually from the center towards the periphery and is formed by spirally winding an oxygenating pipe, two ends of the oxygenating pipe are connected through a connecting pipe, a joint pipe is arranged at the center of the oxygenating disc along with the winding axis of the oxygenating pipe, two ends of the joint pipe are connected with the air delivery pipe and the connecting pipe respectively, an impeller is arranged on the joint pipe and arranged on the outer wall of the joint pipe in a sleeved manner through a bearing, the axial direction of the impeller and the joint pipe form an included angle of 10 degrees to 30 degrees, the oxygenating pipe consists of an inner pipe and a breathable sponge layer coating the outer surface of the inner pipe, and breathable holes penetrating through the wall of the pipe are distributed in the wall of the inner pipe. According to the microporous aerating oxygenation device, the problem that a conventional oxygenating disc sinks to the bottom of water to cause unsmooth air out of breathable holes below can be overcome; as the oxygenating disc has driving force forcing the oxygenating disc to move, the motion range of the oxygenating disc in water can be enlarged, and the oxygenation effect can be further enhanced.

Description

technical field [0001] The invention relates to a water body oxygenation device, in particular to a microporous aeration oxygenation device for water body oxygenation. Background technique [0002] At present, there are two main methods to increase the dissolved oxygen in water: aeration and oxygenation and oxygenation, among which aeration is the main method. Aeration and oxygenation can be divided into blast aeration and mechanical aeration. Mechanical aeration is the impeller, water wheel, jet, etc., by stirring the water, causing the interface contact between water and gas, which can only solve the oxygenation of the upper water body, and the gas-liquid contact interface is intermittent, the contact area is small, and the contact time is short. In terms of noise, the mechanical aerator is placed directly on the water, and the sound of beating the water is very loud, which affects the normal growth of aquatic organisms. Blast aeration is to pass the air delivered by...

Problems solved by technology

However, the current design of the microporous aeration device is not perfect, the distribution of air bubbles is uneven, and the effect of oxygenation needs to be further improved.
