When I used to detoxify the original fume hood of the mineralized laboratory, the sour gas directly passed through the fan and the air duct, which not only made it seriously corroded but also sour gas could easily spread to the entire laboratory, seriously affecting the health of laboratory personnel. To this end, we will be the original detoxification nozzle injection method, and achieved good results. Nozzle ejection detoxification system see attached map. When processing the sample, the fan 1 is started and the air flow is ejected from the nozzle 3 through the air duct 2 to create a negative pressure in the air duct 4 of the fume hood so that ventilation
