  "abstract": "The present invention discloses an air intake and exhaust system of a turbine engine, including an air intake system and an exhaust system. The air intake system is connected to an air inlet of the turbine engine, and the exhaust system is connected to an exhaust port of the turbine engine. The air intake system includes air intake filters and air intake pipings, which are connected to each other. The air intake filters are in V-shaped structures. The exhaust end of the exhaust system is provided with a rain cap. The beneficial effects are as follows: the air intake area is large, the flow rate of the air intake is relatively low, and the air filter has a long life time. The exhaust port is additionally provided with the rain cap, preventing rainwater from accumulating in an exhaust silencer and thus preventing rainwater from possibly flowing backward into and damaging the turbine engine; the opening of the rain cap faces away from the air inlet, preventing the discharged exhaust from being inhaled by the air inlet, and ensuring the quality of air inflow.",

  "description_excerpt": "The present invention relates to the technical field of turbine fracturing, and specifically to an air intake and exhaust system of a turbine engine.\n\nCurrently, power systems for fracturing equipment in oil and gas fields around the world mainly include: diesel engines and electric motors. With the current oil and gas exploitation environment changes, well sites are getting smaller, and the roads to well sites are becoming more and more rugged. For economic reasons, mining costs need to be continuously reduced, including equipment investment costs, equipment maintenance costs, fuel costs, and so on.\n\nHowever, diesel engines have disadvantages of large volumes and heavy weights, exhaust pollution and noise pollution, high fuel costs, and limited access of electric motors to the power grid, making the new trend of turbine engines become very popular. Turbine engines rely on energies released from the combustion of air provided by the air intake system with fuels (wellsite natural gas) for work. Turbine engines have very high requirements on the air intake and exhaust system. The reasonable performances of the air intake and exhaust system of turbine fracturing equipment may affect the operating status of turbine engines, and in turn affect the whole operation progress at fracturing fields. On the one hand, turbine engines have very high air intake demand, which is several times that of an ordinary diesel engine. The air intake area of the existing turbine engine is relatively small. To meet the air intake demand of a turbine engine, due to the small air intake area, the air intake flow rate has to be high.",
