1. A turbine fracturing equipment, comprising:
a turbine engine comprising an exhaust end configured to discharge an exhaust gas;
an exhaust pipe comprising a first end and a second end, the first end of the exhaust pipe being configured such that the exhaust gas discharged from the exhaust end of the turbine engine enters the exhaust pipe via the first end, and the second end of the exhaust pipe being configured to discharge the exhaust gas in the exhaust pipe; and
an exhaust gas energy recovery device comprising a thermal energy recovery mechanism and a kinetic energy recovery mechanism, the thermal energy recovery mechanism being configured to recover thermal energy of the exhaust gas, and the kinetic energy recovery mechanism being configured to recover kinetic energy of a flow of the exhaust gas via wind power generation, wherein at least a part of the thermal energy recovery mechanism and at least a part of the kinetic energy recovery mechanism are arranged in the exhaust pipe,
wherein the kinetic energy recovery mechanism comprises a wind power generation device with fan blades coupled to a rotating shaft, connected to a wind power electric generator, the fan blades covering ¼ to 9/16 of a cross-section of the exhaust pipe when rotating.
