Abstract

The invention relates to a semi-submersible embedded aeration pipe. The semi-submersible embedded aeration pipe comprises a breather pipe and a micro-nano aerator pipe sleeved on the outer side of thebreather pipe. A plurality of air holes are sequentially formed in the breather pipe along the length direction of the breather pipe. Each air hole is radially formed in the pipe wall of the breatherpipe. The breather pipe is sequentially defined as a first section air pipe, a second section air pipe and a third section air pipe along the length direction. Each section of air pipes is respectively provided with air holes which accord with respective rules, so that the whole aeration pipe can generate micro-nano bubbles which are approximately uniformly distributed from the front section to the rear section, and the problem that the existing aeration pipe cannot simultaneously meet the requirements of higher oxygen mass transfer efficiency and underwater water dissolved oxygen concentration is solved.

Description

technical field [0001] The invention relates to the field of aeration devices in the water treatment industry, in particular to a semi-submerged embedded aeration tube. Background technique [0002] The air blower is used to transport the air into the water through the aeration pipe, and then diffuse and escape in the form of bubbles, and dissolve oxygen into the water at the air-liquid interface, which is a common method for providing dissolved oxygen in water. [0003] Existing aeration tubes are divided into perforated aeration tubes and micronano aeration tubes. The perforated aeration tube is to open small holes with diameters of millimeters or centimeters on both sides of the aeration tube. During aeration, the gas is ejected from the small holes on both sides to achieve the purpose of oxygenation and hydraulic disturbance; The larger the pore size, the larger the bubbles formed, which is not conducive to the mass transfer of oxygen in water, and because the oxygen ma...
