The invention relates to a C4F7N mixed gas recycling and inflating device, and belongs to the technical field of recycling and inflating of insulating gas. According to the method, the C4F7N mixed gas is recycled and purified firstly, then the C4F7N mixed gas is stored in a liquid state through low-temperature refrigeration and pressurization, and when inflation is needed, C4F7N, CO2 or O2 is added into the vaporized C4F7N mixed gas to adjust the concentration of the mixed gas for inflation. The C4F7N mixed gas is recycled in a low-temperature refrigeration and pressurization mode and then stored in the container in a liquid state, the filling rate of the container is effectively improved, when inflation is needed, the mixed gas is supplemented to adjust the concentration of the mixed gas, and compared with existing pure C4F7N gas adjustment, the gas adjustment time is shortened, and the adjustment efficiency is improved. 本发明涉及一种C4F7N混合气体回收充气装置，属于绝缘气体的回收充气技术领域。本发明首先对C4F7N混合气体进行回收净化，然后通过低温制冷加压使C4F7N混合气液态储存，在需要
