Combustion heat energy utilization device for mine windblown mine gas

The utility model discloses a combustion heat energy utilization device for mine windblown mine gas, which comprises a main pipeline, a combustor and a backflow pipeline, wherein the main pipeline is provided with a gas inlet and a high-temperature smoke outlet. The combustion heat energy utilization device for the mine windblown mine gas is characterized in that a plurality of copper pipes are evenly distributed along the axial direction of the main pipeline in the main pipeline; two ends of each copper pipe are used for separating a main pipeline cavity and a copper pipe cavity into two separated heat exchange channels by a porous fixed baffle; one end of a first heat exchange channel formed by the copper pipes is connected with the high-temperature smoke outlet; the other end of the first heat exchange channel is connected with an air outlet of the backflow pipeline; a second heat exchange channel surrounded by the inner wall of the main pipeline and the outer wall of each copper pipe is communicated with
