Abstract

The invention relates to an engine waste heat recovery system based on organic rankine cycle, specially a waste heat recovery system for heavy engine. The whole system comprises a plurality of heat exchanger, an energy converting apparatus (turbine power generation apparatus) and corresponding link pipe and valve, wherein the waste heat recovery unit includes a boiling device unit comprising an engine waste gas recycling cooler, an overheating unit and an engine waste gas cooling unit or the like, a reheater of refrigerant, a precooler for pressed air. The working fluid of the whole system is refrigerant such as R245fa. The present waste heat recovery system is more efficient in energy recovery then the waste heat recovery systems in prior art, the operation is more stable, the structure is more compact, and the problem of aluminum material application limitation due to double stage boosting of the high boosting of the engine is solved.

Description

technical field [0001] The invention relates to an engine waste heat recovery system, in particular to an engine waste heat recovery system based on an organic Rankine cycle. Background technique [0002] The ordinary Rankine cycle system is used for steam turbine power generation. This Rankine cycle includes turbines, condensers, pumps, evaporators and other devices. The working medium used is generally water vapor. Water absorbs heat from the evaporator and turns it into high-temperature and high-pressure steam, which drives the turbine to do work and generate electricity. device, to achieve a system loop. The organic Rankine cycle is similar to the ordinary Rankine cycle, except that the working medium is different. Generally, organic fluids are used instead of water, such as R134a, R245fa, etc. [0003] The engine waste heat recovery device based on the organic Rankine cycle uses the energy of the exhaust gas (exhaust gas) from the engine. The low-temperature liquid re...
