Eddy flow bubble formation fine gas bubbles and produce vortex with collision cutting, ensure stable dissolved oxygen to improve the utilization rate of oxygen.
The beneficial effects of the invention are as follows：
1st, drag losses is small, and air blower discharge pressure of fan reduces, and power of motor reduces, and reduces operating cost.
2nd, bubble is collided through multiple rotary and cut, and is formed fine gas bubbles and is produced vortex, increase dissolved oxygen amount is so as to effectively carry
The utilization rate of high oxygen.
3rd, under gaseous mixture water impact rotating flow guidance plate, spiral groove type bubble cutter device, mud will not be hung and block exposure
Device of air.
4th, the check valve that aerator is set will not produce suck-back sewage backflow in the air blower stopping time, protect steam line and
Air blower.
5th, cyclone-static mixed aeration device is with service area is big, dissolved oxygen efficiency is high, drag losses is small, energy consumption is low, stirs
Mix that power is strong, do not block, can intermittent duty, the advantages that service life is long.
