▎ 摘　　要

NOVELTY - The device has a box body provided with a vaporizing cavity and a nitrogen output pipe. The nitrogen output pipe is connected with the vaporizing cavity. A feeding component comprises multiple feeding pipes. Each feeding pipe is connected with a top of the box body and the vaporizing cavity. A microwave generating component comprises microwave generators that are fixed on opposite sides of the box body, and used for emitting microwave in the vaporizing cavity. A wave absorbing component comprises graphene absorbing components arranged in the vaporizing cavity. Each graphene absorbing component is fixed below a connecting port of the corresponding feeding pipes and the box body, and absorbs the microwave energy emitted by the microwave generating component. USE - Microwave liquid nitrogen vaporizing device for use in a liquid nitrogen power converter of a power generating system (all claimed) for converting energy storage of liquid nitrogen into mechanical energy. ADVANTAGE - The device converts the energy storage of the liquid nitrogen into mechanical energy, and is environment-friendly, and has better energy-saving and satisfies use requirement of spare energy, and realizes secondary application of liquid nitrogen. The structure is skilfully designed to satisfy liquid nitrogen, and uses microwave to carry out non-contact heat transfer, which effectively avoids the liquid Nitrogen vaporization of the heating device. The device avoids damage of heating devices caused by partial overheating of nitrogen explosion cylinder phenomenon, ensures vaporized nitrogen stable output, and realizes secondary utilization of the nitrogen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a power generation system.
