Residue heat temperature difference electricity conversion power generation system for internal combustion engine

Abstract

The invention relates to an internal combustion engine waste heat temperature difference electric conversion generation system, which comprises an engine, an exhaust main pipe, a side branch pipe, a flue gas heat exchanger inlet, a flue gas heat exchanger outlet, a silencer, an electrode connecting wire, an electric device, a battery, a circulating water heat exchanger inlet and a circulating water heat exchanger outlet, wherein a temperature difference generating device is arranged between an exhaust port and the silencer of a diesel locomotive, an engine exhaust pipe is divided into the exhaust main pipe and the side branch pipe, the exhaust main pipe is connected with the temperature difference generating device, a flue gas heat exchanger and the flue gas heat exchanger inlet, and the waste heat which is discharged by an internal combustion engine is used as a heat source, circulated cooling water is used as a cold source, thereby doing temperature difference thermoelectric conversion. The internal combustion engine waste heat temperature difference electric conversion generation system has the beneficial effects that a part of power is used to supply power for the electric device of a locomotive, residual parts charge for the battery of the locomotive, thereby being capable of replacing an engine of the locomotive itself, and being capable of saving about 5 percent of fuel oil.

Description

Technical field [0001] The invention belongs to the technical field of thermoelectric power generation by recycling the waste heat of internal combustion engines such as automobiles, trucks, railway locomotives, tanks, armored vehicles and sea ships, and relates to a thermoelectric conversion power generation system of internal combustion engine waste heat. Background technique [0002] Generally, only 30% of the energy generated by the combustion of fuel in an internal combustion engine is converted into mechanical energy. Even if exhaust gas turbocharging technology is adopted, only 50% of the energy is converted into mechanical energy at most. The exhausted flue gas takes 30%-45% of the heat. About 600K~1100K. A large amount of high-grade waste heat is discharged into the atmosphere with the exhaust gas of the internal combustion engine, causing huge energy loss and environmental pollution. How to effectively use the waste heat of the internal combustion engine escaping into t...
