Abstract

The invention belongs to the technical field of safety cabinets, in particular to a ventilation biological safety cabinet, and aims to solve the problem that diffusion of harmful suspended solids and biological aerosol cannot be prevented or reduced in time in the prior art. The ventilation biological safety cabinet comprises a cabinet body, wherein an operation reaction cavity and a storage groove are formed in the upper end and the lower end of the interior of the cabinet body, side doors are fixedly mounted on the two sides of the cabinet body, the middle upper end of one end of the cabinet body is an inclined surface, and a first purification mechanism, a drainage fan and a flow equalizing frame are sequentially and fixedly mounted in the operation reaction cavity from top to bottom. According to the invention, a negative pressure fan and a drainage fan work in sequence, so that filtered and disinfected airflow is purified through a first purification mechanism, subjected to flow speedand direction averaging through aflow equalizing frame, subjected to negative pressure adsorption through a first negative pressure adsorption plate and a second negative pressure adsorption plate, purified through a second purification mechanism in sequence, the whole airflow is discharged from top to bottom, and the possibility of secondary pollution of harmful suspended matters and biological aerosol scattered on the surface and the upper end of the substrate to an experimental sample is avoided.

Description

technical field [0001] The invention relates to the technical field of safety cabinets, in particular to a ventilated biological safety cabinet. Background technique [0002] The biological safety cabinet is a box-type air purification negative pressure safety device that can prevent the aerosol dissipation of certain dangerous or unknown biological particles during the experimental operation process; its working principle is mainly to draw the air in the cabinet outward, so that The cabinet maintains a negative pressure state, and the staff is protected by vertical airflow, and the outside air enters the safety cabinet after being filtered by a high-efficiency air filter to avoid contamination of the processed samples, and the air in the cabinet must also be filtered by a HEPA filter And then discharged into the atmosphere to protect the environment. [0003] The biological safety cabinet can effectively control the emission of polluted air in the operating area through a ...
