The storage tank 10 is hermetically sealed, and a negative pressure is formed in the storage tank 10 under the action of the air pump 20 to drive the air flow from the suction port 301 to the storage tank 10. The mercury is sealed in the storage tank 10, so that the volatilization of the mercury along with the air flow can be reduced, the health and safety of operators can be protected, and the collected mercury can be safely stored. The absorbing mechanism 30 is connected with the storage tank 10 through a communicating pipeline, the liquid level of the sealing agent 11 is lower than the communicating pipeline at the outlet of the storage tank 10, so that after the gas flow carrying mercury is discharged from the communicating pipeline, the mercury in the gas flow falls downwards into the sealing agent 11, and the gas part is discharged outwards under the action of the air pump 20.
