The lower section of auger 6 is provided with gas equipartition device 15, gas equipartition device 15 by system with molecular sieve for preparing at.
Working principle:
Laboratory enters air inlet due to doing after the exhaust gas that experiment generates passes through the exhaust apparatus centralized collection in house first
In pipe 1, there are also experiments will may generate a large amount of exhaust gas during the experiment, at this moment might have an individual air-breathing
Pipe sucking, the perpendicular air inlet pipe 4 being discharged into air inlet pipe 1, the exhaust gas for entering to erect air inlet pipe first passes around auger 6, by auger master
If can play the role that
Firstly, time-limited perpendicular air inlet pipe can be elongated the process length of exhaust gas by auger, in addition, metal material system
At perpendicular air inlet pipe can by the heat absorption in exhaust gas, and then pass through metal fin radiate；
Secondly, auger is by active carbon layer attached outside metallic framework, so as to carry out preliminary adsorption treatment to exhaust gas；Furthermore
Auger can take out, and update replacement, and and treated that auger can remove active carbon layer, to remake, follow
Ring uses；
Then, rotary shaft be it is hollow, outer wall is provided with aperture, can by rotary shaft to be located at auger at exhaust gas into
Row is passed through some gases or liquid is handled；In addition, being to be fixedly connected between packing auger blade and rotary shaft, the present invention is existing
It is technical, tracheae is provided between the two, in addition, packing auger blade below be provided with venthole, can be right by tracheae
The gas that exhaust gas at auger be passed through some sterilizings etc is handled；
Finally, due to which processing contains the exhaust gas of a large amount of dirts for a long time, perpendicular air inlet inside pipe wall may be attached with many attached
Object, auger rotation can be driven by magnet vertical bar by rotary magnetic iron hoop 14 at this time, so that attachment be removed, furthermore magnetic
Iron hoop 14 can be by magnetic force, fixed and adjustment auger position；
It is entered back into gas equipartition device by the gas of auger, it is assumed that without this device, most gas
Can enter the top half of activated carbon adsorption device 8, lower half portion then seldom has gas entrance, be based on this, the present invention this
On the one hand outer molecular sieve can carry out adsorption treatment to exhaust gas, on the other hand can carry out uniformly being distributed to activity to exhaust gas
In charcoal adsorbent equipment 8, one-way ventilating film 7 is provided between activated carbon adsorption device 8 and activated carbon adsorption device 8, thus gas
It enters activated carbon adsorption device 8 and has advanced to infeed tracheae, just can't get out；Activated carbon adsorption device is internally provided with more
The tiny pipeline of item, exhaust gas enter in each pipeline, carry out Batch absorption, so that absorption is more thorough；
It is adsorbed on into the exhaust gas after activated carbon adsorption device into mistake and high polymer absorption tree is entered by hydrophobic permeable membrane
In rouge ball, it is to carry out adsorption treatment to exhaust gas first, secondly, being to hydrophobic that the effect of high polymer absorption resin balls, which mainly has at 2 points,
Ventilated membrane, which is fixed, to be prevented from deforming, and exhaust gas is one-side after all passes through from hydrophobic permeable membrane one end, over time hydrophobic, air-permeability
The fenestra of film can become larger, to not have hydrophobic effect；
The exhaust gas entered in cooling bay later is then exhausted from, and the exhaust gas of discharge enters in escape pipe, and most of gas passes through
Escape pipe discharge, partial gas enter branched pipe, carry out mixed diluting cooling with new exhaust gas again, and circulation is handled.
