Abstract
The present invention is a novel bubble generator that can be used in many different industrial applications. The design of the bubble generator of the invention allows its user to selectively generate gas bubbles in a liquid having a wide range of diameters in the range from microns to millimeters simply by changing the ratio of the flow rate of the gas to that of the liquid. The bubbles are generated at low liquid and gas supply pressure values. The bubble generator of the invention is able to create an unstable liquid flow regime having large amplitudes and frequencies for liquid containing bubbles without the use of moving mechanical parts and drives.
Claims16
A bubble generator that has no moving parts and is configured to generate gas bubbles having a wide range of diameters in a liquid simply by changing the ratio of the flow rate of the gas to that of the liquid, the bubble chamber comprising:
- a. a vortex chamber having a cylindrically shaped wall that defines a vortex chamber cavity;
- b. openings in the cylindrically shaped wall through which the liquid is introduced tangentially into the vortex chamber cavity;
- c. a cylindrical bushing with a blind gas channel that is coaxial with the vortex chamber;
- and
- d. orifices at the lower end of the gas channel in the bushing through which low-velocity gas jets are radially injected into the liquid flow near the center of the vortex chamber cavity.
