Abstract

The invention discloses a purification system for a laboratory fume cupboard. The purification system comprises a purification box (1), a gas inlet pipe (2) penetrating through a top plate of the purification box (1) and stretching into the purification box (1), and an exhaust pipe (3) communicated with the purification box (1). The outer wall of the gas inlet pipe (2) is connected with the top plate of the purification box (1) in a sealed mode. The end face of the gas outlet end of the gas inlet pipe (2) is recessed to form a cylindrical recessed cavity (2.1), and the outer wall of the gas inlet pipe (2) surrounds the wall of the cylindrical recessed cavity (2.1) to form a cavity (2.2). The purification system has the advantages of being high in purification efficiency, good in purification effect, convenient to maintain and easy to use.

Description

technical field [0001] The invention relates to the technical field of environmental purification equipment, in particular to a purification system for laboratory fume hoods. 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. surroundings. 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 purification system for laboratory fume hoods with high purification...
