Abstract
The present disclosure concerns liquid ring systems, including (i) a fixed or rotating casing adapted to contain a liquid, (ii) a rotor located within the casing and having at least one impeller, (iii) a liquid ring formed by rotation of the rotor or the casing, and (iv) a plurality of gas cells formed between the inner surface of the liquid ring and vanes of the impeller. For example, at least one compressing gas cell is in fluid connection with at least one expanding gas cell integrated with the rotor. A liquid valve may include a small gas cell with a reciprocating liquid surface and at least two fluid connections having a free pathway between the connections during an angle of rotation of the rotor and a closed pathway between the connections during 360° minus the angle of rotation.
Claims20
A liquid ring system comprising;
- a housing;
- a rotor mounted inside said housing;
- and
- a liquid ring inside said housing and engaged by said rotor, said liquid ring comprising a liquid and having an inner gas-liquid surface, and said rotor having a number of gas cells defined in part by the liquid in the liquid ring, and at least one wall of each of said gas cells consisting of a part of the inner gas-liquid surface of said liquid ring;
- wherein said part of the inner gas-liquid surface performs a radial reciprocating movement relative to an axis of rotation of said rotor;
- at least one of said gas cells is in fluid connection with at least a positive displacement space integrated with or formed at least in part by said rotor;
- and
- a plurality of the gas cells are in cell to cell gas connection in a chain with at least one other gas cell of said number of gas cells, the plurality of gas cells having a phase difference of between 0° and ±180°, inclusive of ±180°, between minimum gas volumes of the gas cells in cell to cell gas connection.
