Abstract
A pressure exchange device is provided that utilizes an integral high pressure boost pump that is in fluid communication with a pressure exchange unit. An optional low pressure boost pump unit may also be provided. The pressure exchange unit comprises a rotating rotor assembly inside a housing to transfer the pressure of a fluid from one high pressure fluid to another low pressure fluid.
Claims16
A pressure exchange device for the transfer of a fluid comprising:
- a high pressure boost unit comprising;
- a high pressure conduit in fluid communication with an impeller, said impeller configured to raise the pressure of a fluid received through a high pressure inlet port;
- a low pressure conduit in fluid communication with a low pressure fluid source;
- a pressure exchange unit comprising;
- a spinning rotor having a first and second conduit running therethrough;
- wherein said first and second conduit intermittently and opposingly align with said high pressure conduit and said low pressure conduit as said rotor spins;
- a shaft running coaxially through said pressure exchange device, said shaft being further connected to said rotor and said impeller;
- a motive force attached to said shaft.
A system for the filtration of contaminated water to produce potable water comprising:
- a low pressure pump configured to pump the contaminated water to a high pressure pump;
- a high pressure pump configured to receive contaminated water from said low pressure pump and communicate the contaminated water to a filtration device at an elevated pressure;
- said filtration device configured to produce filtered water and waste water, said waste water being expelled at a relatively elevated pressure;
- a pressure exchange device configured to receive said waste water from said filtration device and contaminated water from said low pressure pump, said pressure exchange pump further comprising;
- a high pressure boost unit comprising;
- a high pressure conduit in fluid communication with an impeller, said impeller configured to raise the pressure of a fluid received through a high pressure inlet port;
- a low pressure conduit in fluid communication with a low pressure fluid source;
- a pressure exchange unit comprising;
- a spinning rotor having a first and second conduit running therethrough;
- wherein said first and second conduit intermittently align with said high pressure conduit and said low pressure conduit as said rotor spins;
- a shaft running coaxially through said pressure exchange device, said shaft being further connected to said rotor and said impeller;
- a motive force attached to said shaft.
A pressure exchange apparatus for transferring the energy of pressurization between two fluids, wherein one fluid is at a relatively higher pressure than the other, comprising:
- a high pressure boost unit comprising;
- a high pressure conduit in fluid communication with an impeller, said impeller configured to raise the pressure of a fluid received through a high pressure inlet port;
- a low pressure conduit in fluid communication with a low pressure fluid source;
- a pressure exchange unit comprising;
- a spinning rotor having a first and second conduit running therethrough;
- wherein said first and second conduit intermittently align with said high pressure conduit and said low pressure conduit as said rotor spins;
- a shaft running coaxially through said pressure exchange device, said shaft being further connected to said rotor and said impeller;
- a motive force attached to said shaft.
