| description | The utility model discloses a helium recovery device in the semiconductor wafer processing industry, relates to the technical field of wafer processing, and provides the following scheme aiming at the problems that a wafer drying device provided by the background technology is lack of a helium recovery and purification device, so that helium is wasted and the production cost is increased: the helium recovery device comprises a drying device body and a purification box body, an exhaust hole is formed in one side of the top of the drying device body, an air extracting pump is installed on one side of the top end in the purifying box body, the air extracting end of the air extracting pump is connected with an air extracting pipe, and one end of the air extracting pipe penetrates out of the purifying box body and is connected to the exhaust hole in the drying device body. According to the utility model, by utilizing the dual purification effects of the first separation filter and the second separation filter, the |
