Device for air vortex cooling flame detector

The utility model discloses a device for an air vortex cooling flame detector. The device comprises an air inlet pipe, the vortex tube is provided with a cold/hot air outlet end, and the flame detection mechanism is provided with a probe shell; the flame detector is arranged in the probe shell; the protective goggles are embedded in the probe shell and directly face the detection end of the flame detector; the space between the flame detector and the inner wall of the probe shell forms an air chamber, the probe shell is provided with an air inlet hole which is connected with the cold air outlet end of the vortex tube so as to cool the air chamber, and the probe shell is also provided with a plurality of air outlet holes; according to the device, only a low-pressure air source of 0.4-0.7 MPA is matched with the vortex tube for use, low-temperature gas below 0 DEG C can be generated through the vortex effect of the vortex tube, the temperature of the flame detector is stabilized between 10 DEG C and 15 DEG C al
