Abstract

The utility model provides a microporous aeration pipe used for a microporous aeration device. The aeration pipe is formed by an inner pipe and a breathable spongy layer, wherein air holes running through the pipe walls are uniformly distributed on the surrounding pipe walls of the inner pipe; the spacing between the adjacent air holes is 2-3mm; the outer surface of the inner pipe is wrapped by the breathable spongy layer; all the air holes in the inner pipe are covered by the breathable spongy layer. The microporous aeration pipe has the beneficial effects that by arranging the breathable spongy layer outside the aeration pipe, gases from the breathable spongy layer can be distributed more uniformly, and the generated bubbles are tinier, thus improving the aeration effects.

Description

The micro-pore oxygenation pipe that a kind of micro-pore aeration oxygen increasing device is used

Technical field

The utility model relates to a kind of oxygen-increasing device of water body, the micro-pore oxygenation pipe that specifically a kind of micro-pore aeration oxygen increasing device is used.

Background technology

The method that improves at present water body dissolved oxygen amount mainly contains two kinds: aeration oxygen replenishing and oxygenation agent oxygenation, and wherein take aeration oxygen replenishing as main method.Aeration oxygen replenishing is divided into again two kinds of blast aeration and mechanical aerations.Mechanical aeration is exactly impeller, waterwheel, jetting type etc., by agitate water, causes water to contact with the interface of gas, can only solve the oxygenation of upper strata water body, and gas-to-liquid contact interface is interrupted, and contact area is little, and duration of contact is short.From noise aspect, mechanical aeration is placed directly in waterborne, and the sound of patting water is very large, affects the normal growth of aquatic organism.Blast aeration is that the air of blower fan being carried by pipeline passes into the bottom, carries out aeration from the bottom, can allow dissolved oxygen be distributed in whole water body.And it is best with microporous pipeline oxygenation effect in blast aeration, produce small bubble by the micropore on the pipeline of underwater, and the very small gas so of bubble and liquid contact surface are long-pending also just large, it is slow that bubble rises speed, duration of contact is just long, oxygen in gas is just more abundant like this, in more dissolving easily in water.But the oxygen increasing tube design in microporous aeration device is at present perfect not, bubble distribution inequality, oxygenation effect needs further to improve.

Utility model content

Technical problem to be solved in the utility model is to provide the micro-pore oxygenation pipe that a kind of bubble is tiny and be evenly distributed.

The utility model for solving the problems of the technologies described above adopted technical scheme is: the micro-pore oxygenation pipe that a kind of micro-pore aeration oxygen increasing device is used, oxygen increasing tube is made up of inner tube and ventilative spongy layer, on the tube wall of inner tube surrounding, be evenly distributed with the breather hole that connects tube wall, the spacing of adjacent breather hole is 2-3mm, ventilative spongy layer is wrapped on inner tube outer surface, and all breather holes in inner tube are all covered by ventilative spongy layer.

The beneficial effects of the utility model are: be provided with ventilative spongy layer in the outside of oxygen increasing tube, can make the gas distribution that appears more even, and the bubble producing is more small, has improved oxygenation effect.

Embodiment

Illustrate by reference to the accompanying drawings embodiment of the present utility model.

The micro-pore oxygenation pipe that a kind of micro-pore aeration oxygen increasing device is used, oxygen increasing tube is made up of inner tube 1 and ventilative spongy layer 2, on the tube wall of inner tube 1 surrounding, be evenly distributed with the breather hole 3 that connects tube wall, the spacing of adjacent breather hole 3 is 2-3mm, ventilative spongy layer 2 is wrapped on inner tube 1 outside surface, and all breather holes 3 in inner tube 1 are all covered by ventilative spongy layer 2.Ventilative spongy layer can make the gas distribution that appears more even, and the bubble producing is more small, has improved oxygenation effect.And ventilative spongy layer has water sorption, sky G&W is mixed in the space of ventilative spongy layer, be more conducive to oxygen and dissolve in water.

Claims

1. the micro-pore oxygenation pipe that micro-pore aeration oxygen increasing device is used, it is characterized in that: oxygen increasing tube is made up of inner tube (1) and ventilative spongy layer (2), on the tube wall of inner tube (1) surrounding, be evenly distributed with the breather hole (3) that connects tube wall, the spacing of adjacent breather hole (3) is 2-3mm, ventilative spongy layer (2) is wrapped on inner tube (1) outside surface, and all breather holes (3) in inner tube (1) are all covered by ventilative spongy layer (2).
