Problems solved by technology

In the existing filter devices for the operation and processing of biological experiments, the drainage and inhalation effect of gas is poor, causing some gases not to flow into the filter device for a long time, and the direct-flow airflow guide into the biological experiment cabinet cannot fully drive out its interior The gas has low filtration efficiency, poor sealing, and easy leakage. The in-situ leak detection of the filter is not accurate and the disinfection is not thorough, resulting in gas overflow and environmental pollution.

Abstract

The invention discloses an air port type biological exhaust efficient filtering device which comprises a workbench, a flow collecting cover, a flow guiding device, a circulation monitoring device and a filtering device, the flow collecting cover is arranged on the bottom table top of the workbench, the flow guiding device is installed at the lower end of the flow collecting cover, and air on the bottom table top of the workbench is continuously extracted in real time; the circulation monitoring device is installed at the upper end of the flow collecting cover, the filtering device is installed in the circulation monitoring device, air from the drainage device is filtered through the filtering device, the filtered air is transmitted to the circulation monitoring device to be filtered and detected again in real time, and the filtered air flows back to the filtering device to be circularly filtered.

Description

technical field [0001] The invention relates to the technical field of biological safety protection, in particular to a tuyere-type biological air exhaust high-efficiency filter device. Background technique [0002] During the process of biological experiment operation, some dangerous or unknown biological particles may be produced, and aerosols will be dissipated. Moreover, with the outbreak of the global high-risk and highly contagious new crown pneumonia epidemic, scientific and reasonable epidemic prevention has been launched in various places. Measures, therefore, in the process of biological experiments, it is necessary to carry out exhaust and filtration of the environment where the experiment is located, and filter and discharge the dangerous or unknown biological particles produced in time. In the existing filter devices for the operation and processing of biological experiments, the drainage and inhalation effect of gas is poor, causing some gases not to flow into ...
