Thermoacoustic driving magnetohydrodynamic electricity generation system using ion liquid of room temperature

Abstract

The invention discloses a thermoacoustically driven magnetic fluid power generation system which adopts room temperature ionic liquid. The invention includes a first loop of traveling wave thermoacoustic core, a resonance tube, room temperature ionic liquid, a power generation device and a second loop of traveling wave thermoacoustic core which are connected sequentially ; the invention also includes a frequency stabilizer between the two traveling wave thermoacoustic cores. The traveling wave thermoacoustic core loop includes a feedback tube, an acoustic inductance tube, an acoustic capacitance tube, a first water cooler, a heat regenerator, a heater, a thermal buffer tube and a second water cooler. The power generation device is composed of a rectangle stainless steel outer sleeve, a insulation interlayer, a permanent magnet, electrodes and connecting terminals; and also includes the room temperature ionic liquid which surges periodically. The frequency stabilizer is connected with the traveling wave thermoacoustic cores by two stop valves through two gas storages which has two regulating valves. The thermoacoustically driven magnetic fluid power generation system of the invention brings room temperature ionic liquid into the traditional thermoacoustic engine as the liquid piston, and forms a coupling surge by two phase working medium of gas and liquid; the surge drives the ionic liquid to move back and forth to cut the magnetic line perpendicular to the moving direction, thereby realizing the generation of electricity power.

Description

technical field [0001] The invention relates to a power generation system, in particular to a thermoacoustic driver using room temperature ionic liquid and a magnetic fluid power generation system driven by the same. Background technique [0002] Magnetic fluid power generation, also called MHD power generation, is a power generation technology that has gradually emerged since the 1950s. Magnetic fluid power generation is a new type of high-efficiency power generation method, which is defined as when the magnetic fluid passes through the magnetic field, according to the law of electromagnetic induction, electricity is generated by cutting the magnetic field lines; electrodes are installed on the channel through which the magnetic fluid flows, and are connected to the external load When connected, electrical energy can be output. The traditional generator mainly uses the coil to rotate relative to the magnetic field to generate electricity, because when the coil moves relati...

[0006] It is worth noting that the traveling-wave thermoacoustic system with a loop structure has attracted the attention of researchers and industries due to its high thermoacoustic conversion efficiency. However, the gas working medium may form a DC flow in the traveling-wave loop structure. And cause serious heat loss, even affect the stability of the system

People have developed jet pumps with asymmetric flow resistance and loop DC suppression structures such as elastic membranes to control and eliminate DC and its effects. However, the former has poor adaptability to different working conditions and needs targeted adjustments. The operating life of the operator has yet to be further verified
