Description Of
degassing unitReferring to FIG. 1, the sonic energy wave
degassing unit generally indicated at 10 includes a fluid supply pipe 12 which has an outlet 14 through which sonic energy treated fluid emerges after passing through the sonic energy transducer and aeration assemblies 16, 18, and 20.
Power is applied to the assemblies 16 and 18 respectively from the frequency oscillator and amplifier units 24 and 26 along lines 28.
The fluid containing enlarged gaseous bubbles from the unit is discharged from the pipe end 14 to appropriate discharge devices.
FIG. 2 is a section of the sonic energy transducer and aeration assemblies of FIG. 2 showing fluid flow proceeding from a direction of right to left. The fluid initially encounters first stage high frequency sonic generator 16. This unit has a cylindrical high frequency sonic transducer housing 30 fabricated from aluminum with radial ribs 32. Rubber spacer gaskets are disposed between each end of the housing 30 and the adjacent fluid conduit sections. A piezoelectric transducer 34 is disposed on the ribs 32. They transmit sonic energy from the sonic transducer housing to the passing fluid. This is the initial primary gas bubble stage in which high frequency sonic waves produce small nuclei of gas 36 in the standing wave zone 38 within the immediate confines of the cylindrical housing 30. The high frequency sonic generator 16 develops in this zone a standing wave having a frequency and intensity that is matched with the frequency and intensity of the standing wave developed in zone 50 by the low frequency generator stage 18.
