UNIT FUNCTIONING AS HEAT-AND MASS EXCHANGER, TURBINE AND PUMP - HTP Russian patent published in 2011 - IPC F03B3/10 F01D1/36 F28C3/06 F04F5/14 

FIELD: machine building.

SUBSTANCE: unit functioning as heat and mass exchanger, turbine and pump consists of case, of ferrule (section of pipe) or of two ferrules of different diametre successively interconnected and equipped with front and back end covers, of washer (circular partition) with central orifice for water inlet installed at distance from front cover, and of tangential or radial branches for water supply connected to case between front cover and washer. The unit also consists of a steam line connected with an internal part of the case via an intermediate steam chamber around the case and via tangential nozzles passing through the wall of the case. The unit includes an outlet pipeline of hot water connected to the case tangentially. Disks are successively put on at a distance from each other and fixed on the shaft inside the case along its axis. A working wheel of the pump (centrifugal or axial) is arranged and fixed between the washer and disks on the shaft; or an elongated end of the shaft projects beyond the front end cover and is connected to the shaft of the centrifugal pump, while the pump proper is installed into an inset of the pipeline supplying water to the unit.

EFFECT: simultaneous utilisation of internal power of steam for water contact heating and for kinetic power of steam for mechanical operation with satisfactory efficiency of utilisation of steam kinetic energy.
