Aeration pipe with pipe end being hemispheric aeration plate

Abstract

An aeration pipe with pipe end being a hemispheric aeration plate comprises an air-inlet connection pipe, an air-inlet sleeve head, a gas guiding chamber, an inner pipe, an outer pipe, a rubber aeration pipe membrane and a hemispheric pipe end; the inner pipe and the outer pipe are coaxially arranged, and a gas channel is formed between the outer pipe and the inner pipe; the rubber aeration pipe membrane is adhered to the exterior of the outer pipe; the peripheral body of the outer pipe is uniformly provided with multiple equal-diameter circular through holes; the rubber aeration pipe membrane is densely provided with multiple aeration micropores; the inner pipe, the outer pipe and the rubber aeration pipe membrane form a pipe body of the aeration pipe, two ends of the pipe body are both the hemispheric pipe ends which both have a structure same to that of the pipe body and are in mutual communication; the air-inlet sleeve head is disposed between the air-inlet connection pipe and the gas guiding chamber; the connection pipe guides air into the gas guiding chamber at two sides through the air-inlet sleeve head; and the gas guiding chamber is U-shaped and has an enclosed inner segment, and the bottom of the gas guiding chamber is provided with a gas port communicated with the gas channel. The pipe end, which cannot participate aeration, of a conventional aeration pipe is modified and designed as a hemispheric aeration plate, so that the aeration acting scope of the aeration pipe is effectively expanded, and also aeration effect is improved.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aeration tube whose tube end is a hemispherical aeration plate. Background technique [0002] When treating urban domestic sewage, an aerobic process is often used to treat the sewage. How to improve the treatment effect of the aeration and oxygenation system while saving engineering costs has always been a key issue in sewage treatment. [0003] In the Chinese patent (application number: CN200920105273) titled "A perforated aeration tube for sewage biochemical treatment", a perforated aeration tube for sewage biochemical treatment is disclosed, including a perforated aeration tube, A number of equal-diameter circular perforations are evenly arranged on the wall of the perforated aeration tube on a straight line in the length direction, and the diameter of the circular perforations is 6-9mm. Install the perforated aeration pipe in the sewage treatment tank through a fixed ...

AI Technical Summary

Problems solved by technology

This type of aerator adopts a flat plate structure, which can only diffuse air bubbles in the direction perpendicular to the plate, and cannot achieve 360° all-round aeration. On the one hand, the aeration service area will be too limited compared with the tubular aerator, requiring more Large laying density increases the material consumption; on the other hand, it will cause the rising trajectory of the diffused bubbles in the water to be parallel to each other. The effect of sewage treatment
