A device for generating electricity by using exhaust waste heat and sound waves

Abstract

The invention discloses a device of conducting power generation by utilizing waste heat and sound waves of tail gases, which comprises a tail gas waste heat power generating unit and a tail gas sound wave power generating unit, wherein the tail gas waste heat power generating unit comprises a heat collector, a Stirling generator, and a radiator, the heat collector is connected with a heat cavity of the Stirling generator through a heat cavity pipe, a cold cavity of the Stirling generator is connected with the radiator through a cold cavity pipe, and the radiator is connected with the heat collector through an air inlet pipe; the tail gas sound wave power generating unit comprises a helmholtz resonator, a magnet, and a metal ring, the metal ring is connected onto a drumhead of the helmholtz resonator, and the magnet generates a magnetic field cut by the metal ring when the metal ring vibrates repeatedly with the drumhead; the tail gas waste heat power generating unit and the tail gas sound wave power generating unit are arranged in sequence in the flowing direction of the tail gases. The device can effectively reduce the energy consumption, relieves the growing global greenhouse effect, and achieves the effect of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of automobile energy saving and emission reduction, in particular to a device for generating electricity by using waste heat and sound waves of exhaust pipe exhaust gas of automobiles. Background technique [0002] Energy shortage and environmental pollution are global problems, which are increasingly attracting people's attention, and are also two major problems restricting the sustainable development of the automobile industry. The exhaust gas produced after engine combustion is discharged into the atmosphere through the exhaust pipe. It has the characteristics of high temperature, high pressure, and high energy. The energy contained in the exhaust gas accounts for most of the energy consumed and wasted by the engine. A lot of heat is wasted, making engines burn fuel inefficiently, while also putting more pressure on the already serious global warming effect. [0003] There are three ways to deal with aut...
