Peculiar smell eliminating system for SPF (specific pathogen free)-grade experimental animal room

The utility model discloses a peculiar smell eliminating system for an SPF-level experimental animal room. The peculiar smell eliminating system comprises a fresh air processing section, an air inlet pipe is arranged on the left side of the fresh air processing section, an air supply pipe is arranged on the right side of the fresh air processing section, a conveying fan is installed on the inner side of the air supply pipe, a storage chamber is arranged at the bottom of the air supply pipe, and an exhaust section is arranged at one end of the storage chamber. By the adoption of the structure, fresh air can be preliminarily filtered through the primary filter screen in the fresh air treatment section, impurities are prevented from entering the fresh air treatment section, then peculiar smell doped in the fresh air can be adsorbed through the activated carbon net, and therefore the peculiar smell eliminating effect is achieved; and then the efficient filtering assembly is used for completely filtering fresh air
