Disinfecting and filtering device for air outlet of clean room

Abstract

The invention relates to a disinfecting and filtering device for an exhaust outlet of a clean room. The device comprises an exhaust duct assembly in which a filtering assembly is arranged, the exhaust duct assembly comprises a transition pipe and an air outlet and an air outlet respectively formed at two ends of the transition pipe; a U-shaped air channel is arranged in the transition pipe, the filtering assembly is installed in the U-shaped air channel, a water outlet is formed in the lowest point position of the U-shaped air channel, the transition pipe is provided with a liquid inlet assembly, and the liquid inlet assembly extends into the U-shaped air channel; meanwhile, the liquid inlet assembly is positioned above the filtering assembly; a second electromagnetic valve is mounted at the water outlet, and when the second electromagnetic valve is in a closed state, disinfectant is poured into the U-shaped air channel through the liquid inlet assembly, so that the disinfectant submerges the filtering assembly; and when the second electromagnetic valve is in an open state, the disinfectant in the U-shaped air channel is discharged from the water outlet, and then disinfection treatment on the filtering assembly in the exhaust duct assembly is completed.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a disinfection filter device for an air exhaust port of a clean room. Background technique [0002] In the field of filter ports, especially in clean cabins with high germ content, such as wards or germ research laboratories, in order to ensure the air quality in the cabin, an air circulation system will be used; during the air circulation process, through the filter element Filter the germs so that the germs stay on the filter element. In actual use, the filter element can only filter most of the viruses, and when the concentration of the germs is lower than the limit value, the exhausted airflow can be considered safe. When filtering After the element has been used for a period of time, the concentration of germs remaining on the filter element increases with time, which will lead to an increase in the concentration of germs in the exhaust airflow after filtering from the fi...

[0002] In the field of filter ports, especially in clean cabins with high germ content, such as wards or germ research laboratories, in order to ensure the air quality in the cabin, an air circulation system will be used; during the air circulation process, through the filter element Filter the germs so that the germs stay on the filter element. In actual use, the filter element can only filter most of the viruses, and when the concentration of the germs is lower than the limit value, the exhausted airflow can be considered safe. When filtering After the element has been used for a period of time, the concentration of germs remaining on the filter element increases with time, which will lead to an increase in the concentration of germs in the exhaust airflow after filtering from the filter element, thereby affecting the filtration efficiency. When the concentration of germs in the exhaust airflow increases When it reaches a certain value, it will be considered that the filter element can no longer be used and needs to be replaced. At present, the filter element needs to be taken out from the exhaust system for replacement. However, the accumulated germs on the filter element will come into contact with the operator. It will even spread into the air, causing damage to the human body
