[0040] As a preferred embodiment, the cross-sectional area of ​​the nozzle blade grid gradually decreases along the axial direction.

[0041] As a preferred embodiment, the guide vane cascade has a constant blade cross-sectional area.

[0042] The working process of the utility model is roughly as follows:

[0043] The exhaust gas enters the upper shell 1 and the upper shell 23, flows to both sides of the shell through the branching port, and then flows through the nozzle blade grid, expands, and the pressure is reduced, thereby increasing the intake speed. At the same time, the combined action of each nozzle blade grid and each guide blade grid makes the gas move along the corresponding trajectory, and successively impacts the moving blade grids on the left and right sides, so that each moving blade grid rotates, driving the main shaft 37 to rotate. The utility model device converts the kinetic energy and thermal energy of the exhaust gas into mechanical energy for the rotation of the main shaft 37, and finally converts it into electrical energy to realize the recycling of energy. The device is miniature and lightweight, economical and practical, highly feasible, and highly practical in design, and has broad market prospects and good economic benefits.

[0044] The working process of the utility model is specifically as follows:

[0045] The external exhaust gas first passes through the upper shell 1 and the pneumatic quick connector 28 into the upper shell 23, first flows to both sides of the shell through the branch port, and then flows through the nozzle blade A29, the nozzle blade B30, the nozzle blade C32, the nozzle blade D33, the nozzle blade E35, and the nozzle blade F36. The fan blade curve is designed so that the cross-sectional area of ​​each nozzle blade gradually decreases along the axial direction, so that the channel between two adjacent fan blades gradually increases along the axial direction, so that the gas expands and the pressure decreases, thereby increasing the intake speed. At the same time, through the combined action of each nozzle cascade and the guide cascade A31 and guide cascade B34, the gas runs along the corresponding trajectory. The gas flowing to the left side sequentially impacts the moving blade E42, the moving blade F43, the moving blade G44, and the moving blade H45 according to the corresponding trajectory, and the gas flowing to the right side sequentially impacts the moving blade D41, the moving blade C40, the moving blade B39, and the moving blade A38 according to the corresponding trajectory. Each moving blade is matched with the main shaft 37 through a key. Due to the curvature of each moving blade blade, the kinetic energy of the gas impacting each moving blade is converted into mechanical energy, so that each moving blade rotates, driving the main shaft 37 to rotate, while the nozzle cascade and the guide cascade are fixed to the upper shell 23 and the lower shell 20, and do not rotate with the main shaft 37. The rotating main shaft 37 is connected to the torque speed sensor 9 through a coupling, and the torque is further transmitted for power generation, realizing the conversion of wind energy and thermal energy into mechanical energy, and then further converted into electrical energy, realizing the recycling of energy.
