High-efficiency power generation device by utilizing automobile tail gas

Abstract

The invention discloses a high-efficiency power generation device by utilizing automobile tail gas. The device mainly comprises an air suction pipe, a spark plug, a device for preparing carbon dioxide by tail gas, a motion cylinder, a sliding body, a spring, a crank link mechanism, a power generator, a thermoelectric power generation sheet, a tail gas gathering chamber, a liquid carbon dioxide cooling chamber and the like. According to the invention, the flow rate of the high-temperature tail gas at the position of a horn at the connecting end of an exhaust pipe and the motion cylinder is accelerated, and negative pressure is caused, thus the air suction pipe sucks fresh air, a mixed gas is formed, and enters the motion cylinder; the spark plug is ignited continuously for secondary combustion, high-temperature and high-pressure tail gas is generated, the sliding body is pushed to move forward, and simultaneously, after the high-temperature tail gas generated by the secondary combustion enters the tail gas gathering chamber through small holes at the bottom of the motion cylinder, pressure is reduced, the power generator is driven by a crank shaft and a crank link mechanism to generate electricity through the reciprocating pulling effect which is formed by the reversal motion of the sliding body by the spring, at the same time, electric power is generated through temperature sensing of the temperature difference of the tail gas gathering cavity and the liquid carbon dioxide cooling cavity by utilizing the thermoelectric power generation sheet, and the electricity energy is stored in an automobile battery.

Description

technical field [0001] The invention relates to the field of tail gas power generation, belongs to the technical field of energy regeneration, and particularly refers to a high-efficiency power generation device using tail gas. Background technique [0002] As the economy continues to develop, cars are becoming more and more common. However, automobiles are the main way to consume energy such as oil. The temperature of the exhaust gas emitted by automobiles is as high as 500°C~600°C. If it is directly discharged into the atmosphere, it will easily pollute the atmosphere and cause a large amount of heat energy loss. Therefore, how to fully and effectively utilize the heat energy of exhaust gas is a hot spot worthy of attention. Using automobile exhaust to generate electricity is one of the measures to make full use of fuel energy, improve efficiency, and be beneficial to environmental protection.
