Micro gas turbine power generation range extender

Abstract

The invention discloses a micro gas turbine power generation range extender which comprises a shell assembly, a generator composed of a stator and a rotor, a rotating shaft connected to the rotor, anda compressor turbine and a gas turbine arranged on the rotating shaft, wherein the shell assembly comprises an air inlet part shell, a compressor volute, a gas volute and an exhausting volute. The generator is arranged at the center in the air inlet part shell. A generator shell is arranged outside the generator. An annular air inlet is formed between the generator shell and the air inlet part shell. The compressor turbine and the gas turbine are separately arranged in the compressor volute and the gas volute, a compressor outlet is formed in the compressor volute, and a gas inlet is formed in the gas volute. A combustor is arranged on the outer side of the shell assembly. The micro gas turbine power generation range extender is compact in structure. Compared with a conventional gas turbine, the integral length is further reduced, a product is miniaturized, the micro gas turbine power generation range extender is mounted to an automobile conveniently, and the automobile body space issaved.

Description

technical field [0001] The invention relates to the technical field of automobile range extension, in particular to a micro gas turbine power generation range extender. Background technique [0002] At present, the number of vehicles in the world is about 1.12 billion, and the total daily fuel consumption is about 403.2 billion liters per day. The number of vehicles in my country has exceeded 310 million, and the number of car drivers in the country has reached 320 million. The volume is about 108 billion liters per day, and the carbon monoxide and hydrocarbons in the exhaust emissions exceed 80%, and the nitrogen oxides and particulate matter exceed 90%. [0003] Motor vehicles are the main contributors to air pollution emissions. Diesel trucks, which account for 7.8% of the car population, emit 57.3% of nitrogen oxides and 77.8% of particulate matter. As the main source of urban air pollution, respiratory diseases caused by air pollution are increasing day by day, seriousl...
