Description

Tubular aeration device Technical Field The utility model relates to the technical field of aeration equipment, in particular to a tubular aeration device. Background The tubular aeration device is core equipment for oxygenating water in a sewage treatment process, and mainly conveys air (or oxygen) into water through a pipeline or an aeration head to provide oxygen required by metabolism for aerobic microorganisms so as to ensure the stable operation of treatment processes such as an activated sludge method, a biomembrane method and the like. The structural design and performance of the sewage treatment device directly influence the sewage treatment efficiency, energy consumption and operation cost. In the traditional tubular aeration device, bubbles are released through fixed micropores, mesopores or gaps, the particle size of the bubbles is larger, the gas-liquid contact area is limited, so that the oxygen mass transfer efficiency is lower, and especially when treating high-concentration organic wastewater or deep water scenes, longer aeration time or larger aeration flow is needed to compensate, so that the energy consumption is increased, the aeration time is prolonged, repeated cleaning is needed when the aeration Kong Pinfan is blocked, the aging of materials is possibly accelerated, and the service life is shortened. When using, the aeration pipe can be influenced by air current impact and water flow fluctuation easily, and severe vibration and shaking are generated, so that abrasion of a pipeline, an aeration hole and a connecting part is accelerated, the pipeline is broken and the air leakage risk is caused, once the pipeline breaks down, the whole system is required to be shut down and emptied during maintenance, the disassembly is complicated, the maintenance period is long, a large amount of manpower and material resources are required to be consumed for integral disassembly, the maintenance workload and cost are increased, the equipment downtime is further prolonged, and the sewage treatment cost is increased.
