Air treatment system for biological laboratory

Abstract

The invention discloses an air treatment system for a biological laboratory. The system comprises a fresh air unit, a fresh air pipe set, a fresh air distribution device, an exhaust pipe set, an exhaust unit and a flow guide device, wherein a surface air cooler, a primary filter and a medium-efficiency filter are sequentially arranged between the fresh air unit and the fresh air pipe set, the fresh air pipe set comprises a main fresh air pipe and all levels of secondary fresh air pipes, tail ends of the secondary fresh air pipes are connected with a fresh air distribution box body, a tail endof the fresh air distribution box body is connected with the fresh air distribution device, the exhaust unit comprises a main exhaust pipe and all levels of secondary exhaust pipes, the exhaust pipe at the tail end is connected with the flow guide device, and the main exhaust pipe is connected with the exhaust unit after being connected with a waste gas treatment device so as to exhaust the treated waste gas. The system is advantaged in that the airflow runs in one direction, backflow and disorder are avoided, and the fresh air distribution device of an air supply outlet effectively prevents the airflow from directly blowing the head of a worker.

Description

technical field [0001] The invention relates to an air treatment system, in particular to a biological laboratory air treatment system. Background technique [0002] With the rapid development of pathology, new technologies, new methods and new instruments are widely used in pathological diagnosis and research, which improves the accuracy of case diagnosis and improves the understanding of disease etiology, pathological changes and disease development process. regularity of research levels. However, the accompanying problems such as exhaust gas and other harmful gas emissions and environmental pollution in the pathology laboratory are also concerned. Strengthening the emission of laboratory exhaust gas is conducive to improving the working environment of the laboratory, avoiding environmental pollution, maintaining public safety and protecting the health of laboratory staff. [0003] In order to solve the problem of air pollution in the biological laboratory and the harm t...

AI Technical Summary

Problems solved by technology

In order to ensure the air quality of the laboratory, it is unreasonable to increase the exhaust air volume and the number of exhaust outlets, increase the suction volume and the number of suction outlets, and only increase the air volume to solve the problem of air pollution, because Blindly increasing the air volume will cause the airflow in the laboratory to form a vortex area and splash back, causing the toxic gas to spread to other corners of the laboratory, which is not conducive to the discharge of toxic gas
