1. A purging system for a turbine fracturing apparatus group, wherein the turbine fracturing apparatus group comprises a plurality of turbine fracturing apparatuses, each of the plurality of turbine fracturing apparatuses comprises a gas turbine, each gas turbine comprises a plurality of fuel supply pipelines, the purging system comprising:
a first air compressor and a purging pipeline, wherein the purging pipeline is configured to communicate the first air compressor with the plurality of fuel supply pipelines of each gas turbine in the turbine fracturing apparatus group, the first air compressor is configured to, in a case where at least part of the plurality of fuel supply pipelines is stopped from supplying fuel, supply compressed air to the at least part of the plurality of fuel supply pipelines which has been stopped from supplying fuel, so as to perform purging;
an air storage device connected to the purging pipeline, wherein the purging pipeline comprises a first purging pipeline and a second purging pipeline, an air inlet of the air storage device is communicated with the first air compressor through the first purging pipeline, and an air outlet of the air storage device is communicated with the plurality of fuel supply pipelines of each gas turbine in the turbine fracturing apparatus group through the second purging pipeline;
a pressure sensor configured to detect a pressure inside the air storage device and generate a pressure signal;
a power device connected to the first air compressor and configured to drive the air compressor; and
a control device connected to the power device and configured to control the power device,
wherein:
the power device comprises a hydraulic motor, and the control device comprises a processor and a solenoid valve, the processor is respectively communicatively connected to the pressure sensor and the solenoid valve, and is configured to control the solenoid valve according to the pressure signal of the pressure sensor so as to adjust a rotating speed of the hydraulic motor, thereby adjusting a pressure and a flow rate of the compressed air generated by the first air compressor, or;
the power device comprises an electric motor, and the control device comprises a processor, wherein the processor is communicatively connected to the pressure sensor and configured to control a rotating speed of the electric motor according to the pressure signal of the pressure sensor, thereby adjusting a pressure and a flow rate of the compressed air generated by the first air compressor.
