High-efficiency divergent type microporous aerator

Abstract

The invention discloses a high-efficiency divergent type microporous aerator. The high-efficiency divergent type microporous aerator comprises a supporting pipe and a diaphragm sleeving the surface of the supporting pipe, wherein aerating holes are uniformly distributed on the supporting pipe; and the thickness of the diaphragm coated on the upper surface of the supporting pipe is larger than that of the diaphragm coated on the lower surface of the supporting pipe. The high-efficiency divergent type microporous aerator disclosed by the invention has the advantages that the thickness of the diaphragm is gradually changed, the resistance is uniform, the ventilation volume is large, the service life is long, the aeration area is large and the bottom of a pond is not easy to deposit mud.

Description

technical field [0001] The invention relates to a high-efficiency divergent aerator for water treatment and oxygenation, in particular to a microporous aerator with a thick upper layer and a thinner lower layer of an aeration membrane, uniform aeration, long service life, and high utilization rate of the aeration area. Background technique [0002] Diaphragm aerator is used in water treatment to supply the required air (oxygen) as a kind of oxygenation equipment. Because of its advantages of small diffusion bubbles, large air-water contact surface and high oxygen exchange rate, it is widely used at present. The basic structure is the air pipe, the support pipe connected to the air pipe, etc., and the diaphragm wrapped on the support pipe is generally made of EPDM rubber, silicone rubber, plastic and other mixed materials. Air (or oxygen 〉It is sprayed out from the micropores of the dia...

AI Technical Summary

Problems solved by technology

[0004] Ordinary tube-type microporous aerators have low aerator area utilization rate, uneven aeration, aeration rubber diaphragm is only in the upper half, and the convex shape is bulging when working, the upper aeration volume is large, while the lower aeration The air volume is small or even non-existent; the aeration pressure and aeration volume are concentrated in the upper part of the tube aerator, resulting in a large pressure on the upper part of the aerator, which is easy to tear and strain

There are disadvantages of low utilization of the aeration area of ​​the aerator, poor aeration effect, low efficiency, fragile diaphragm, high oxygen utilization rate, and high energy consumption.
