Abstract
The utility model discloses a closed radiopharmaceutical ventilation cabinet with an activated carbon filtering mechanism, which comprises a machine body for radiopharmaceuticals and an air pump for air exhaust, and a control panel is mounted at the upper end of the front surface of the machine body for radiopharmaceuticals. The active carbon filters and the like are installed, so that when the device is used, on one hand, the air pump for exhausting air is started, and air in the radiopharmaceutical machine body can be continuously exhausted through branch exhaust pipes at the tail ends of the three active carbon filters communicated with the air pump for exhausting air; by means of the air pump for exhausting air, air can be continuously exhausted from the interior of the radiopharmaceutical machine body through the exhaust system, pollution caused by outward diffusion of the air during operation can be effectively prevented, and on the other hand, the air exhausted by the air pump for exhausting can be filtered and purified under the filtering and purifying effect of an activated carbon filtering layer in the activated carbon filter. And the discharged gas is ensured to reach the emission standard.
