preferably, the inner pipe and the outer pipe are both made of 316L stainless steel material.
According to the scheme, the pipeline leakage caused by strong corrosivity of methanol fuel is avoided through the 316L stainless steel material, and meanwhile, the conditions that the inner pipe and the outer pipe are welded to form a closed environment are met through the inner pipe and the outer pipe which are made of the same material.
Preferably, the inner pipe and the outer pipe are welded and fixed into a whole.
The supporting frame comprises a ring body and a plurality of connecting rods arranged on the periphery of the ring body, the connecting rods are uniformly distributed along the circumferential direction of the ring body, and the inner diameter of the ring body is matched with the outer wall of the inner pipe.
According to the scheme, the support frame is fixed on the inner pipe through the ring body, and the support frame is connected with the inner pipe and the outer pipe through the connecting rod.
Preferably, the ring body is provided with four connecting rods, and the outer end faces of the connecting rods are in contact with the inner wall of the outer pipe.
Preferably, the methanol concentration detector is electrically connected with an external alarm.
According to the scheme, the methanol concentration detector is electrically connected with the external alarm, so that when the methanol concentration in the pipeline space between the outer pipe and the inner pipe is too high, a crew is reminded to execute safety measures in time.
