As shown in fig. 1-2, the technical scheme adopted by the utility model is as follows: an experimental console for purifying return air and waste gas in a laboratory, comprising: laboratory bench 6, purification cabin 5, equipment compartment 3 and exhaust duct 1. The purification cabin 5 is fixedly arranged at the lower part of the experiment table 6, the upper part of the purification cabin 5 is provided with an exhaust hole, the exhaust hole is used for communicating the purification cabin 5 with the experiment table 6, and two purification adsorption materials 51 are fixedly arranged in the purification cabin 5. The equipment cabin 3 is fixedly arranged at the lower part of the purification cabin 5, an exhaust assembly is fixedly arranged in the equipment cabin 3, and the exhaust assembly is communicated with the purification cabin 5. The exhaust duct 1 is fixedly arranged at one end, close to the exhaust hole, of the experiment table 6, the exhaust duct 1 is vertically arranged, and the lower end of the exhaust duct 1 is communicated with the equipment cabin 3. The exhaust assembly is used for exhausting the air in the purification cabin 5, so that the air pressure near the exhaust hole is reduced, the exhaust gas generated in the experimental process is conveniently introduced into the purification cabin 5 through the exhaust hole, and is exhausted outdoors through the exhaust duct 1 after being filtered by the purification adsorption material 51, so that the harm of harmful gas generated in the experiment to the health of a human body is avoided.

The experiment table 6 top symmetry is provided with backup pad 8, fixedly be provided with reagent frame 7 between the backup pad 8, be convenient for put and use of experimental reagent. The fixed guide plate 2 that is provided with in below of reagent frame 7, the lower extreme of guide plate 2 is located the top of exhaust hole, and the gas that the experiment produced is blocked by guide plate 2 to follow guide plate 2 and get into purification cabin 5 from the exhaust hole under exhaust assembly's suction, improved the purifying effect of this operation panel. The middle part of the guide plate 2 is fixedly provided with an illuminating lamp 21, so that experiment illumination is facilitated, and favorable support is provided for experiment.

The exhaust assembly comprises an exhaust fan and an exhaust tube 33, the shock absorber 4 is fixedly arranged in the equipment compartment 3, the exhaust fan 32 is fixedly arranged on the shock absorber 4, and adverse effects on the experimental process caused by vibration of the operation of the exhaust fan 32 are avoided. One end of the exhaust pipe 33 is communicated with the purification cabin 5, and the other end of the exhaust pipe 33 is communicated with the input end of the exhaust fan. The equipment compartment 3 is close to the one end of exhaust duct 1 and has seted up through-hole 31, through-hole 31 communicates exhaust duct 1 and equipment compartment 3, and exhaust duct 1 corresponds with the output of exhaust fan.
