Low energy liquid degasification system and method
A low energy liquid degasification device has a liquid reservoir connected to an input channel above it and a cylinder below it. The input channel has several embedded isolation valves which allow the channel to be closed off into several independent chambers. The cylinder has a piston capable of moving up and down under the action of an actuator located below it and which seals the cylinder. Upon filling the liquid reservoir, input channel, and cylinder above the piston with a largely incompressible and inexpansible liquid and sealing the isolation valves, the piston is moved downward increasing the enclosed volume and generating a vacuum. Agitation of the assembly produces cavitation and pressure waves inside, generating bubbling that removes dissolved gas from the liquid.
1 . A low energy degasification system, comprising:
a chamber assembly having interior surfaces, the chamber assembly configured to contain a quantity of liquid;
one or more of a plurality of valves configured to enable liquid to enter and exit the chamber assembly, wherein at least one of the one or more valves is a top valve that is attached to a top of the chamber assembly, wherein the liquid injected into the chamber assembly completely fills an internal volume of the chamber assembly to the top valve, displacing any gas inside the chamber assembly during the filling of the chamber assembly;
an expansion system configured to expand and contract the internal volume of the chamber assembly while the chamber assembly remains sealed, wherein the expanding of the internal volume of the chamber assembly by the expansion system causes the liquid to move towards the bottom of the chamber assembly, creates a vacuum within the chamber assembly, and create a head space above the liquid in the chamber assembly; and
a cavitation generator associated with the chamber assembly, wherein activation of the cavitation generator creates motion in the liquid within the pressurized chamber assembly that generates cavitation events within the liquid, and accelerates the generation of bubbles from dissolved gas in the liquid, wherein gas bubbles emerge, rise to, and empty into the head space above the liquid,
wherein the interior surface of the chamber assembly has a shape, construction, and surface smoothness that enables release of the gas bubbles which adhere to the interior surfaces in response to liquid flow within the chamber assembly, and
wherein contraction of the chamber assembly, via the expansion system, creates the liquid flow within the chamber assembly that releases any gas bubbles adhering to interior surfaces of the chamber assembly, prevents dead zones from forming within the head space that was created when the chamber assembly was expanded, and pushes the gas in the head space out of the chamber assembly through the one or more top valves.
2 . The system of claim 1 , wherein the expansion system comprises a piston and cylinder that are attached to the chamber assembly to form the internal volume capable of being expanded by moving the piston within the cylinder.
3 . The system of claim 1 , wherein the activation of the cavitation generator further comprises physical movement of the chamber assembly at a velocity and direction that generates one or more cavitation events.
4 .

an expansion system configured to expand and contract the internal volume of the chamber assembly while the chamber assembly remains sealed, wherein the expanding of the internal volume of the chamber assembly creates a vacuum within the chamber assembly and creates a head space above the liquid in the chamber assembly; and
a cavitation generator associated with the chamber assembly, wherein activation of the cavitation generator creates motion in the liquid within the vacuumed chamber assembly that accelerates the generation of gas bubbles within the liquid,
wherein the interior surface of the chamber assembly has a shape, construction, and surface smoothness that enables release of the gas bubbles from interior surfaces of the chamber assembly, in response to liquid flow within the chamber assembly from contraction of the chamber assembly that pushes the gas in the head space out of the chamber assembly through the valve.
9 . The system of claim 8 , wherein the expansion system comprises a piston and cylinder that are attached to the chamber assembly to form the internal volume capable of being expanded by moving the piston within the cylinder.
