A power transmission assembly is arranged inside the exhaust pipe 1. At the output end of the power transmission assembly, two meshing bevel gears 3 are provided. The bevel gear 3 far from the power transmission assembly is connected to the input end of a speed change device 4 through a transmission shaft 13. The output end of the speed change device 4 is connected to the input end of a generator 5. A voltage stabilizing transformer 6 is arranged at the output end of the generator 5.

[0022] By setting the power transmission assembly, this device can utilize the pressure energy during the emission of fermentation tail gas in the biological fermentation process for transmission, transmit it to the generator, and then convert it into electric energy. It has a simple structure, is easy to use, reduces the energy consumption during the fermentation process, and increases the economic benefits of the enterprise.

[0023] In this embodiment, the power transmission component includes an impeller 2, an impeller shaft fixing bracket 8, an impeller fixing seat 9, and an impeller shaft 10. Both ends of the impeller shaft 10 are arranged in the exhaust pipe 1 through the impeller shaft fixing bracket 8. A plurality of impeller fixing seats 9 are evenly arranged on the outer wall of the impeller shaft 10, and a plurality of impellers 2 are evenly arranged on the impeller fixing seats 9.

[0024] Four impeller fixing seats 9 are provided, and three impellers 2 are respectively arranged on each impeller fixing seat 9. The impellers 2 on different impeller fixing seats 9 are staggered.

[0025] Limit clips 7 for clamping on the impeller shaft fixing bracket 8 are arranged at both ends of the impeller shaft 10.

[0026] The impeller shaft fixing bracket 8 is in a circular ring shape. The outer diameter of the impeller shaft fixing bracket 8 is adapted to the inner diameter of the exhaust pipe 1, and a card slot 14 for inserting the impeller shaft 10 is arranged at the center of the impeller shaft fixing bracket 8.
