Abstract

A motionless pumping design that reduces operation and maintenance costs, and enhances reliability in three aspects of pneumatics system configuration. A motionless and corrosion-resistant pump which uses the continuous generation of pressure variation push/pull force by relying on the venturi effect induced by a pair of gas ejectors together with an argon pneumatic sub-system.

First claim

What is claimed is:

1 . A motionless and corrosion-resistant pumping system that leverages the pressure variation of a push/pull force comprising: a plurality of gas ejectors located on a pulsation tube and a salt storage vessel wherein a pressure variation unbalance arises between the pulsation causing molten salt to be either pumped into the pulsation tube by the removal of gas or driven back to the salt vessel by the addition of gas; a first and second valve operable between an open and closed position; when said first valve is opened, and said second valve is closed, intake gas flow prompts the secondary flow out of the pulsation tube leading to the suction of molten salt from the salt vessel to the pulsation tube due to pressure decreasing; when said first valve is closed, and said second valve is open, intake gas flow prompts the secondary flow out of the pulsation tube leading to the molten salt suction from the salt vessel to the pulsation tube due to pressure owing to pressure increasing.

2 . The motionless and corrosion-resistant pumping system of claim 1 wherein a closed loop configuration allows for higher pump efficiency.

3 . The motionless and corrosion-resistant pumping system of claim 1 further including a plurality of flow diodes that regulate the fluid flow direction, and prevent reverse flow by exploiting vertex resistance generated by geometrical patterns.

4 . The motionless and corrosion-resistant pumping system of claim 1 wherein harmonic coordination between multiple gas flow circuits is fine-tuned by a microchip unit controllers and computer automation algorithms.

5 . The motionless and corrosion-resistant pumping system of claim 4 wherein stable and continuous flow of molten salt is controlled by opening and closing said plurality of valves.
