Abstract

The invention discloses a smoke purifying system of a laboratory ventilation hood. The smoke purifying system comprises a purifying box (1), a smoke inlet pipe (2) penetrating through a top plate of the purifying box (1) to extend into the purifying box (1) and a ventilation pipe (3) communicated with the purifying box (1). The outer wall of the smoke inlet pipe (2) is in sealed connection with the top plate of the purifying box (1), and the end face of the smoke outlet end of the smoke inlet pipe (2) is sunken inwards to form a columnar concave cavity (2.1). The smoke purifying system has the advantages of being high in purifying efficiency, good in purifying effect, convenient to maintain and easy to use.

Description

technical field [0001] The invention relates to the technical field of environmental protection purification equipment, in particular to a laboratory fume hood flue gas purification system. Background technique [0002] Fume hoods are an integral part of laboratory ventilation design. In order to prevent laboratory workers from inhaling or ingesting some toxic, pathogenic or unknown toxic chemicals and organisms, there should be good ventilation in the laboratory. In order to prevent the absorption of some particles (smoke, soot, dust and aerosol), the pollutants must be removed with a fume hood, otherwise it will directly affect the health of the experimenters, but direct emission will seriously affect the air quality and destroy the ecology. environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above shortcomings of the prior art: to provide a laboratory fume hood flue gas purification system with...
