The utility model provides an exhaust
system for a laboratory, which comprises a suction unit, a
waste gas treatment unit and a
waste gas discharge unit, and the suction unit is used for capturing
waste gas; the waste gas
treatment unit comprises a dust removal mechanism, a
spray tower, a
drying tower and a
carbon adsorption box which are connected in sequence, and the dust removal mechanism is connected with the suction unit; the waste gas
discharge unit is connected with the
carbon adsorption box and is used for discharging waste gas to the outside; the suction unit comprises a first pipeline, a second pipeline and a main pipeline, the first pipeline is used for being connected with an exhaust outlet of the synthesis experiment cabinet, the second pipeline is connected with a fixed exhaust hood and a universal exhaust hood which are located above the detection experiment operation table, the air inlet end of the main pipeline is connected with the first pipeline and the second pipeline, and the air outlet end of the main pipeline is connected with the dust removal mechanism. The exhaust
system for the laboratory, provided by the utility model, can effectively remove pollutants such as
smoke dust, flammable and explosive substances, organic non-
methane hydrocarbons and the like in waste gas, so that the possibility of safety accidents is reduced, and the safety of the surrounding environment and personnel is guaranteed.
