Embodiment
As shown in Figure 1, a kind of environmentally protective Muffle furnace apparatus, including Muffle furnace main body, the Muffle furnace main body include
Heating unit 5 and the heating furnace 12 above heating unit 5.Operating surface is installed on the housing of the heating unit 5
Plate 3, the top of the heating furnace 12 offer exhausting-gas hole 1 and are provided with push button switch door 2 in the sidepiece of heating furnace 12.
The Muffle furnace apparatus further includes exhaust gas processing device, and the exhaust gas processing device includes vertically-mounted heat sink 8 and lives
Property charcoal adsorbent equipment 9.In the present embodiment, a leakage switch 4, and the heating are installed on the housing of the heating unit 5
Burner hearth 12 selects light aluminum oxide ceramic fibre burner hearth.
In the present embodiment, the heat sink 8 is specially the internal babinet that aqueous solution is housed.The lower end of heat sink 8 leads to
Cross that appendix 6 is connected with exhausting-gas hole 1, its top is connected by pipe fitting with the top of activated carbon adsorption device 9.The activated carbon is inhaled
The lower end of adsorption device 9 is connected with exhaust pipe 11, for further filtration, purification pernicious gas, under activated carbon adsorption device 9
End is provided with slotted plate 10.In order to control gas to enter the flow of heat sink 8, a control valve is installed on appendix 6
7。
In the present embodiment, the activated carbon adsorption device 9 includes the hollow housing of both ends open, the hollow housing it is interior
Portion is provided with activated carbon adsorption bed, and is connected with the device for being filled with ammonia in the side of hollow housing.
When the utility model is used, first, power on, after opening earth leakage circuit-breaker on inspection operation panel 3
Temp control indicator is then shut off earth leakage circuit-breaker whether in the range of 25-30 DEG C of room temperature；Then push button switch door is opened
2, check whether heating furnace 12 has the sample not taken out or catalyst to roast debris, opening exhausting-gas hole 1 after inspection, and with
Appendix 6 connects, and opens control valve 7, and ammonia is filled with into activated carbon adsorption bed, you can added into heating furnace 12 to be added
The material of heat/burning, Muffle furnace main body are started to work.The tail gas that the substance release of heating/roasting goes out in Muffle furnace main body exists
The process of the exhaust gas processing device is as follows：
1) tail gas subsequently enters activated carbon adsorption bed after exhausting-gas hole 1 out carries out cooling processing into heat sink 8
In, the SO2 wherein in tail gas is first subject to the physisorption of activated carbon, and under the action of O2 and H2O, SO2 further by
Catalysis, H2O4 and NH4SHSO4 is generated after oxidation reaction occurs, and is stored in the micropore of activated carbon；And NOx is in the condition of NH3
Under, after being subject to the catalytic action of activated carbon surface, redox reaction generation N2 occurs.That is the change of the generation of activated carbon adsorption bed
It is as follows to learn reaction：
SO2+2H2O+O2 → H2SO4,
H2SO4+NH3 → NH4HSO4,
4NO+4NH3+O2→4N2+6H2O。
2) tail gas after exhaust gas processing device, SO2 and NOx gases removal rate can reach 95% and 90% respectively；And
And after activated carbon adsorption bed is reaching saturation absorption, it is sent in regenerating unit and carries out heating desorption, activated carbon is not failing
On the premise of it is reusable.
SO2 and NOx content are relatively low in the tail gas gone out due to Muffle furnace body bleeder, and the floor height of activated carbon adsorption bed can be set
Put between 92-100mm, to avoid the replacement repeatedly of activated carbon, activated carbon adsorption bed except by SO2 in tail gas and NOx and into
Row purification is outer, can also remove the noxious material such as volatile organic matter in tail gas, at the same by accessory substance H2SO4 and NH4HSO4 into
Row recycles.
It these are only the embodiment of explanation the utility model, be not intended to limit the present invention, for this area
For technical staff, where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
