What is the efficiency of oxygen transfer in a tube aerator?

The tubular aerator product is a new tubular rubber aerator developed by our company. It consists of a membrane tube, a liner, a connector, a plug and a clamp. The gas supply main pipe and the pilot gas groove can be opened with a rubber membrane for microporous aeration. The utility model has the advantages of simple structure, high oxygen utilization rate, reliable performance, no clogging of air holes, no backflow of sewage, uniform circumferential force, long service life, convenient installation and maintenance, and the like.

First, the effect of oxygen transfer efficiency of tubular aerator:

The tubular aerator has good chemical stability, no plasticizer, long-lasting elasticity, acid and alkali resistance, no hardening, no embrittlement, no aging, 360 ° all-round oxygenation, small bubble diameter, both Maintaining a high oxygen conversion rate can also agitate the bottom sludge.

Tubular aerator - can improve the gas distribution system of the aeration pipe is relatively simple, a 1m (8m3 / h) aeration pipe tube ventilation equivalent to four 200m3 / h disk, making the entire system leakage rate Low, at the same time, due to the small number of joints of the aeration pipe system, its air resistance loss is small and energy consumption is small.

The aeration tube adopts a gas guiding groove to make the air distribution inside the aerator quickly and evenly, so that the aeration membrane tube is evenly stressed, prolonging the life of the aeration membrane tube and releasing the uniformity of the bubble, and improving the aeration effect; The gas trough is a narrow groove, and the rubber membrane tube area on the gas groove does not open the aeration hole. When the gas supply is stopped, the rubber film is closely attached to the gas guiding groove, thereby preventing the sewage from being poured.
