[0002] The tubular aerator is a device that injects high-pressure gas into the aeration pipe; the tubular aerator is composed of a membrane tube, a liner, a center tube, a plug, a threaded sleeve and a gasket. The air supply main pipe and the pilot air groove can be opened with a rubber membrane to perform microporous aeration, disperse the gas into small bubbles and spread them in the activated sludge. Through the relative flow between the bubbles and the water, the mass transfer between the gas and the water is accelerated, and the dissolved oxygen concentration is increased. The installation of the tubular aerator is to screw the tubular aerator into the prefabricated distributor, and the distributor is connected to the air distribution branch pipe.

[0003] In the prior art, tubular aerators mostly use square tube distributors, which are in the form of thread heads. The thread head square tube distributor is a square tube that is directly welded with a thread head, which is then connected to the distributor. The inevitable deformation of the thread head welding causes the end of the aeration tube to be severely tilted, making it difficult to make the aeration tube parallel and horizontal, affecting the uniformity of aeration. Therefore, we propose a connector for tubular aerators to solve the above problems. Utility Model Content
