Marine methanol fuel supply system heat exchange equipment

The invention discloses marine methanol fuel supply system heat exchange equipment which comprises a vortex tube unit connected with a compressed air supply unit and a methanol heat exchanger unit used for exchanging heat with the vortex tube unit, the vortex tube unit comprises a tee joint internally provided with a vortex tube, the inlet end of the tee joint is a normal-temperature compressed air inlet, and the outlet end of the tee joint is a normal-temperature compressed air outlet. The two outlet ends are a high-temperature hot air outlet and a low-temperature cold air outlet respectively, the normal-temperature compressed air inlet is communicated with the compressed air supply unit, and the low-temperature cold air outlet and the high-temperature hot air outlet are communicated with a heat exchange medium inlet of the methanol heat exchanger unit respectively. A vortex tube heat exchange mode is adopted, a compressed air system directly discharges methanol into a fuel preparation room or the atmosphere
