WASTE HEAT RECOVERY SYSTEM FOR PUMP SYSTEM Russian patent published in 2016 - IPC F02G5/04 F02B63/04 F01P3/18 F04D25/06 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in pump systems with internal combustion engine for pumping of liquids. System (10) includes internal combustion engine (28), generator (29), driven by internal combustion engine, and pump unit (12), powered by generator (29). Pump unit (12) includes first pump (24A) configured to obtain first liquid component, second pump (24B) configured to obtain second liquid component, manifold (22) configured to receive first and second liquid components from first and second pumps (24A), (24B), dispensing device, receiving first and second liquid components from manifold (22), and heat recuperation system. Dispenser comprises mixing head, mixing first and second liquid components. Heat regeneration system provides thermal coupling of internal combustion engine (28) with pump unit (12). Heat recuperation system produces heat generated by internal combustion engine (28), and sends extracted heat to pump unit (12) for separate heating of first liquid component and second liquid component before mixing first and second liquid components by means of mixing head. Disclosed are versions of systems design.

EFFECT: technical result consists in improvement of waste heat recovery.
