Liquid-state fuel expansion fission device capable of refrigerating, and liquid-state fuel expansion fission method

The invention relates to the technical field of liquid-state fuel treatment, particularly to a liquid-state fuel expansion fission device capable of refrigerating, and a liquid-state fuel expansion fission method. According to the present invention, a liquid-state fuel is sprayed into a fission pipe in a high-speed atomizing flow manner through a high-pressure gas, and continuously collides the fission pipe and various high-speed atomizing flows to form a liquid-gas fuel, and the liquid-gas fuel is output through an outlet pipe so as to be used; through a resonance box, the impact on the fission pipe by the high-pressure gas in the resonance box and the liquid-state fuel vaporization in the fission pipe is subjected to resonance so as to strengthen the liquid-state fuel vaporization; the outlet pipe uses a T-shaped pipe, and the large mist droplets entrained in the gas fuel flow fall into a liquid outlet due to gravity so as to be recovered; an atomization endothermic process is used for a cold gas preparatio
