Energy recovery device of automobile exhaust

Abstract

An energy recovery device of automobile exhaust comprises a thermoelectric power generation device and an electrolytic hydrogen production device, wherein the electrolytic hydrogen production device comprises an electrolyzer, a hydrogen separator, a supercharger and a hydrogen storage device. The thermoelectric power generation device supplies power to the electrolyzer, the hydrogen separator and the electrolyzer are communicated with the supercharger, an outlet of the supercharger is communicated with an inlet of the hydrogen storage device, and the hydrogen storage device is sequentially communicated with an air intake channel of a motor through a hydrogen permeation control valve and a backfire preventing device. The hydrogen control valve is connected with a controller in a control mode, wherein the controller is connected with the hydrogen permeation control valve and the throttle valve opening sensor which is installed at the position of a throttle valve of the motor simultaneously. A safety switch valve which is used for pressure limiting is further arranged on the hydrogen storage device. The invention relates to a technology of energy recovery and recycling. Electric power generated by the thermoelectric power generation device can be utilized continuously, and the energy recovery utilization effect of the automobile exhaust is good. Changes of the motor are hardly needed, performances of the motor can be improved, the power performance and the emission performance of the motor are improved, and fuel consumption of the automobile is reduced.

Description

technical field [0001] The invention relates to energy recovery and recycling technology, in particular to a recycling and recycling device for automobile exhaust energy. Background technique [0002] The automobile industry is one of the pillar industries of my country's national economy. With the development of the automobile industry, the energy consumed by vehicles is also increasing day by day. At present, the power conversion efficiency of automobiles is only about 40%, and as many as 60% of the energy in fuel has not been effectively utilized. If 10% of this energy is utilized, it will bring good social and considerable economic benefits. [0003] Announced on October 21, 2009, the Chinese patent document with the announcement number CN 201332370Y and the name "A device for generating electricity by temperature difference using a vehicle exhaust pipe" discloses a vehicle exhaust energy recovery device, which "can provide vehicles with Part of the electric energy. It ...

AI Technical Summary

Problems solved by technology

"According to the description of the patent specification, the device described in this patent that utilizes the vehicle exhaust pipe for thermoelectric power generation is electrically connected to the vehicle battery, and the recovery and utilization of vehicle exhaust energy is realized by charging the generated electric energy to the battery. The existing problem is that : When the car battery is in a saturated state, it is necessary to cut off the electrical connection between the thermoelectric power generation device and the car battery to prevent the car battery from being overcharged and damage or reduce the service life. The problem of poor recycling
