Anti-break paddle type aeration support tube and aeration method thereof

Abstract

The invention belongs to the technical field of sewage treatment plants, and particularly relates to an anti-rupture paddle-board-type aeration support tube. The invention is characterized in that the anti-rupture paddle-board-type aeration support tube is composed of a tube body, a ball check valve, a saddle-type connecting seat, air holes, a plug and an air duct, wherein the tube body is in the shape of a paddle board; one end of the tube body is connected with the saddle-type connecting seat; the air duct, which is perforated left and right, is arranged in the tube body; one end of the air duct is plugged by a plug, and is connected with and communicates with the valve seat; the ball check valve is arranged in the valve seat; the ball check valve can translate in the valve seat; and the lower part of the tube body is uniformly provided with the plurality of air holes. Compared with the traditional tubular aeration support tube, the support tube provided by the invention increases the aeration area by 50%, and replaces the circular air outlet surface of the tubular aeration with the cambered air outlet surface, thereby enhancing the aeration uniformity. The overall aeration efficiency is enhanced by 50% or above. The cost and energy consumption are saved.

Description

[technical field] [0001] The invention belongs to the technical field of sewage treatment devices, and in particular relates to an anti-crack paddle type aeration support tube. [Background technique] [0002] At present, as a kind of oxygen supply equipment, the aerator is widely used in the sewage treatment industry. The microporous tube aerator is a commonly used aerator. It wraps a diaphragm with tiny self-closing pores on the support tube and tightens it with clamps at both ends. When working, the air blower is used to transport the air through the air pipeline to the aerator located at the bottom of the pool. The compressed air enters between the support tube and the diaphragm, and the micropores on the surface of the diaphragm will automatically open under the air pressure while the diaphragm expands. The air diffuses out in the form of bubbles, dissolves oxygen into the water at the air-liquid interface, and oxygenates the water; if the air pressure disappears, the d...

Problems solved by technology

[0003] The diaphragms of the current tubular and plate diaphragm microporous aerators are easy to tear. Once part of the diaphragms in the biochemical tank are torn, the bubbles will be enlarged, which not only affects the aeration efficiency, but also increases energy consumption. And affect the normal operation of the sewage plant

Often need to stop running, turn on the water and replace
