Compared with prior art, the utility model has the beneficial effects that：
1) the pressure water inlet of the efficient dissolved air pot of the utility model utilizes ejector principle similar to ejector, water inlet：①
Make air by high-velocity flow cutting, be ground into microbubble, gas-water contact area is significantly greatly increased, accelerates air solution rate.2. penetrating
Stream forms negative relative, reduces pressure needed for air inlet, saves energy consumption.The admission pressure of traditional dissolving need to be more than or equal in tank
Pressure, and this equipment admission pressure can reduce by more than 50, general pressure inside the tank about 0.4MPa, admission pressure only needs 0.15MPa.
2) flow high speed tangentially enters, and forms eddy flow, moves ahead in efficient dissolved air pot inside spin, it is short to avoid flow
Road extends the air-water contact time --- and this equipment hydraulic detention time only needs 60-90 seconds；Eddy flow forms centrifugal force simultaneously,
Water is set to be moved to tank skin, and undissolved air pocket is then assembled to center, and air pocket is avoided to be escaped from outlet, influences air supporting effect
Fruit.
3) efficient dissolved air pot installs (≤90 °) at a certain angle, convenient for remaining undissolved collect air in high-efficiency dissolued-air
Tank top is discharged.
4) compressed air inlet sets needle valve and flowmeter, convenient for pressing in runoff investigation air mass flow；Surplus air exports
If automatic exhaust steam valve, pressurize can exclude rapidly surplus air simultaneously, and dissolving slack tank is avoided to run.
