Abstract
The invention relates to a hybrid power system with a waste heat recovery function and an environment air purification function and for a hydrogen vehicle. The hybrid power system with the waste heat recovery function and the environment air purification function and for the hydrogen vehicle comprises a vehicle body, a transmission system, a hydrogen fuel engine, a hybrid power transmission, a metal hydride storage tank, a turbine, a catalyst, a high-pressure surge tank, a hydrogen buffering tank and the like. The metal hydride storage tank is connected to an inlet of the turbine through the high-pressure surge tank. An outlet of the turbine is connected to an inlet of the hydrogen fuel engine through the hydrogen buffering tank or a high-pressure hydrogen buffering tank. An outlet of the hydrogen fuel engine is connected to a discharge outlet through the catalyst, a tail gas heat exchanger, a residual hydrogen absorption unit and a tail gas zero-stage purifier. The hydrogen fuel engine is connected with the hybrid power transmission through a power output shaft. According to the hybrid power system with the waste heat recovery function and the environment air purification function and for the hydrogen vehicle, the hydrogen fuel engine, the turbine and an exhaust gas waste heat recovery and purification system are combined to form the hybrid power system for the automobile, chemical energy of hydrogen is sufficiently used, various kinds of heat energy in the process is recovered, and the working efficiency of the power system is improved; and atmospheric pollution is avoided, the environment air is purified, and protection of the natural environment is facilitated.
Description
technical field [0001] The invention belongs to the technical field of power machinery and relates to a vehicle power system, in particular to a hydrogen energy vehicle hybrid power system capable of recovering waste heat and purifying ambient air. Background technique [0002] In the 21st century, the automobile engine industry has developed rapidly, but gasoline engines and diesel engines are still the main types of automobile engines. Gasoline and diesel are non-renewable resources. In order to alleviate a series of negative effects brought about by the shortage of petroleum resources and reduce air pollution and vehicle engine exhaust emissions, it is necessary to find alternative fuels for engines, and hydrogen energy is currently the most ideal clean fuel. . Hydrogen energy is a renewable resource among many alternative energy sources. It has a high calorific value and most of the products after combustion are water vapor. It is an ideal green fuel. Hydrogen energy a...
