Miniature low-temperature sulfur hexafluoride recovery device

The miniature low-temperature sulfur hexafluoride recovery device comprises an air pump, a condensation generator and a refrigerating machine, the air pump is installed on the condensation generator, the condensation generator comprises a cavity and a heat exchanger arranged in the cavity, one end of the cavity is provided with an opening, the refrigerating machine is installed at the opening and connected with the heat exchanger, and the refrigerating machine is connected with the heat exchanger. The cavity and the refrigerating machine form a closed space for containing sulfur hexafluoride gas, and the gas pump is communicated with the closed space through a gas pipe. The air pump and the refrigerating machine are both integrated on the condensation generator, the size of the device can be greatly reduced, sulfur hexafluoride gas is pressurized by the air pump and introduced into the cavity of the condensation generator, the sulfur hexafluoride gas can be subjected to heat exchange with the heat exchanger t
