Carbon dioxide pre-energized fracturing equipment

The invention discloses carbon dioxide front energizing fracturing equipment which comprises a liquid carbon dioxide pumping set, a buffer tank, a pressurizing manifold, a backflow manifold, a carbon dioxide separation device, a fracturing fluid pumping set, a fracturing blender truck and a pump truck. A plurality of tank bodies in the liquid carbon dioxide pumping group are communicated with a buffer tank through an integrated manifold; the buffer tank is communicated with the liquid inlet end of the carbon dioxide separation device through a pressurizing manifold; the liquid outlet end of the carbon dioxide separation device is communicated with the pump truck, and the gas outlet end of the carbon dioxide separation device is communicated with the buffer tank through a reflux manifold; a plurality of tank bodies in the fracturing fluid pumping group are communicated with a fracturing blender truck through an integrated manifold; the fracturing blender truck is connected to a connecting pipeline of the carbo
