[0019] In the above specific embodiment, a screw feeder 2 is provided at the top of the impregnation bin 1 to realize automatic loading of the catalyst carrier. The catalyst carrier is impregnated with the impregnation liquid in the impregnation bin 1. After the impregnation is completed, the catalyst carrier and the impregnation liquid are separated by a separation component, and the catalyst carrier is discharged through a screw discharger 6. The impregnation liquid passes through the filter plate 5 and enters the containing box 4. In the reverse operation of the present utility model, the catalyst carrier is convenient to load and unload, and the impregnation liquid carried on the catalyst carrier can be filtered through the filter plate 5, and the impregnation liquid is convenient to collect.

[0020] An electric butterfly valve 7 is provided above the separation component, and the electric butterfly valve 7 is used to control the closing of the discharge port 3. When the catalyst carrier is in an impregnation state, the electric butterfly valve 7 is in a closed state.

The catalyst carrier is transported upward by the first spiral rod 62, which can realize the separation of the catalyst carrier and the impregnation liquid. The catalyst carrier is unloaded through the discharge port 3 of the shell 61. During the catalyst transportation process, the liquid impregnation liquid carried on the catalyst carrier can fall into the collecting shell 64 through the liquid leakage port 63. The collecting shell 64 is also inclined and is arranged coaxially with the shell 61. The impregnation liquid in the collecting shell 64 slides along the inner wall of the collecting shell 64 and enters the containing box 4 through the pipeline.
