Abstract
This utility model discloses a biological laboratory ventilation device, relating to the field of laboratory ventilation, including an activated carbon box. A box cover is rotatably mounted on the top plate of the activated carbon box. A bottom pipe is installed at the bottom end of the activated carbon box. A connection port aligned with the top opening of the bottom pipe is opened on the bottom plate of the activated carbon box. One bottom pipe near the air inlet is not connected to the other bottom pipes, while the other multiple bottom pipes are grouped together with adjacent bottom pipes. Bottom pipes in different groups are not connected. Two symmetrically distributed porous intercepting nets are fixedly installed at both ends of the inner wall of the activated carbon box. A first vertical plate is fixedly installed at the bottom end of the inner wall of the activated carbon box, and a second vertical plate is fixedly installed between the top and bottom ends of the inner wall of the activated carbon box. This utility model, by setting up the connection head, the first vertical plate, and the second vertical plate, can realize the flow of gas along the air channel formed by these three components, thereby improving the utilization rate of activated carbon.
