The invention discloses an organic Rankine cycle-based automotive tail gas waste heat recovery and power generation system. The organic Rankine cycle-based automotive tail gas waste heat recovery andpower generation system comprises a first heat circulation unit, a second heat circulation unit and a power generation unit, wherein the first heat circulation unit, the second heat circulation unit and the power generation unit are separately connected to a second heat exchanger, a third heat exchanger and an expansion machine circularly, and a second working medium finishes thermoelectric conversion through a circulation path; the second working medium is output from the third heat exchanger, the second heat exchanger absorbs heat of a first working medium, and the expansion machine convertsheat energy into mechanical energy for acting to drive a generator to generate electricity; and the second working medium after acting returns to the second heat circulation unit through the third heat exchanger for condensation. The organic Rankine cycle-based automotive tail gas waste heat recovery and power generation system disclosed by the invention not only improves the energy utilization ratio of the engine, but also reduces emission of automotive tail gas on environmental heat pollution, so that the purpose of saving energy and reducing emission is achieved. Meanwhile, development offuel-electricity mixed novel automobiles is facilitated.
Description
technical field [0001] The invention belongs to the field of waste heat recovery of automobile exhaust, and in particular relates to a power generation system for recovery of waste heat of automobile tail gas based on an organic Rankine cycle. Background technique [0002] Energy is the support and driving force of national economic development, and also an important material basis for social development. However, for many years, the low efficiency, high consumption and environmental pollution in my country's energy development and utilization have been restricting the sustainable development of economy and society. Effective recovery of waste heat resources is an important means to improve energy utilization efficiency. [0003] At present, automobile engines, especially the engines of heavy-duty transport vehicles, will emit a large amount of low-temperature exhaust gas at 80-200°C, and its energy utilization rate is generally low. Studies have shown that the heat equival...
