Title:
SAFETY CABINET AND PHOTOCATALYST FILTER UNIT USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/023880
Kind Code:
A1
Abstract:
Provided is a safety cabinet capable of reliably preventing a situation in which an anticancer agent in a workspace is diffused into an installation chamber by an external discharge airflow, thereby exposing an operator to the anticancer agent.　A housing 51 has provided therein a photocatalyst filter 52 and a black light 53, as well as a plenum 57 that causes a first external discharge airflow Z1 to flow into the photocatalyst filter 52 at a desired filter inflow air velocity while satisfying a prescribed air velocity condition pertaining to the air velocity of an unpurified airflow X. The desired filter inflow air velocity is selected from an appropriate range in which the anticancer agent decomposing action of the photocatalyst filter 57 is attained at a desired level or higher. The inflow-side cross-sectional area Aa of the plenum 57 is set to be the same as or larger than the opening area Ac of an exhaust port 19. The outflow-side cross-sectional area Ab of the plenum 57 is set according to the air volume of a second external discharge airflow Z2 such that the first external discharge airflow Z1 flows into the photocatalyst filter 57 at the desired filter inflow air velocity.
