The process is cumbersome, labor-intensive, and workers are easily exposed to a dangerous environment with high mercury concentrations. In addition, a large amount of mercury-containing dust is generated, which is extremely dangerous.

[0026] Specifically, during use, the filter module 5 is the core component of the entire structure. Four electric actuators 502 are bolted and fixed inside the mounting cylinder 501. These four actuators 502 are arranged symmetrically in two groups. Each group of actuators 502 has a second mounting plate 503 fastened to both sides to enhance structural stability and distribute stress. A placement frame 504 is fixedly mounted on the upper surface of each of the four actuators 502. When the placement frame 504 is activated, it moves upwards. Sliding blocks are fixed to the inner walls of both sides of the placement frame 504, allowing the adsorption bed 505 to slide within it.
