Description

TECHNICAL FIELD

[0001] The present application relates to the air purification technical field, especially to an IVC deodorization system. BACKGROUND

[0002] IVC is the abbreviation of individual ventilated cages, and the Chinese name is called independent ventilation cage. The independent ventilation cage refers to a feeding and experimental equipment that can operate and feed SPF experimental animals in a clean bench, in which clean air is sent into a closed independent unit (such as a cage or a box), and waste gas is concentrated and discharged. SPF animals (specific pathogen-free animals) refer to animals that do not carry specific pathogens and parasites that may interfere with experiments on the basis of clean animals, and need to be fed in a barrier system and implement strict microbial and parasite control.

[0003] At present, when the IVP discharges waste gas, the waste gas is directly sucked from the environment of the animals being fed into the exhaust duct through the exhaust pipe, and then passes through the ultraviolet catalytic unit and the activated carbon adsorption unit to remove harmful substances in the waste gas before being discharged into the external environment.

[0004] However, impurities such as animal hair inevitably exist in the animal feeding environment. If the animal hair is directly filtered through the filter screen, since the diameters of the animal hair are different, the filter holes of the filter screen are too small to affect the ventilation rate. The animal hair is in the form of a long strip and is extremely easy to pass through the filter holes. If the filter holes are too large, the filtering effect is not good. Therefore, most of the existing IVP exhaust systems do not set animal hair filtering devices, and directly suck the waste gas in the animal feeding environment into the exhaust pipe. Impurities such as animal hair are easy to adhere to the exhaust duct or be adsorbed on the activated carbon adsorption unit, which has the defect of easily causing pollution of the duct and clogging of the activated carbon adsorption unit.
