Muffle furnace apparatus, it can handle the pernicious gases such as S02, NOx that inanimate matter roasting process in Muffle furnace is discharged.
To achieve the above object, the present invention is achieved through the following technical solutions：
A kind of Muffle furnace apparatus of environmental protection, including Muffle furnace main body, the Muffle furnace main body include heater and
Guidance panel, the heating furnace are installed on the heating furnace above heater, the housing of the heater
Top offer steam vent and key switch door, in addition to exhaust gas processing device, institute be installed in the sidepiece of heating furnace
Exhaust gas processing device is stated including vertically-mounted heat sink and absorbent charcoal adsorber, the lower end of the heat sink passes through defeated
Tracheae is connected with steam vent, its top is connected by the top of pipe fitting and absorbent charcoal adsorber, under absorbent charcoal adsorber
End is connected with blast pipe；One control valve is installed on appendix.
In such scheme, for further filtering noxious gas, it can be provided with the lower end of absorbent charcoal adsorber with holes
Sieve plate.
It is the structure of predigested running device and cost-effective in such scheme, the absorbent charcoal adsorber includes two
The hollow housing of end opening, the inside of the hollow housing is provided with activated carbon adsorption bed, and is connected in the side of hollow housing
There is the device for being filled with ammonia.
In such scheme, the heat sink is specifically as follows the internal casing that the aqueous solution is housed.
In such scheme, to be further ensured that security that Muffle furnace is used, it can pacify on the housing of the heater
Equipped with a leakage switch；While the heat insulation effect in order to improve Muffle furnace, the heating furnace is excellent from milk high temperature, heat insulation effect
Good light aluminum oxide ceramic fibre burner hearth.
The present invention beneficial aspects be：
The present invention is improved in the Muffle furnace apparatus of existing structure, and by the exhaust gas processing device of setting, high temperature is roasted
The pernicious gases such as the SO2 and NOx that are produced during burning carry out purified treatment, have purified environment, have reduced pernicious gas to environment
Luxuriantly, simple in construction, environmental protection, is beneficial to promote.

Embodiment
As shown in figure 1, a kind of Muffle furnace apparatus of environmental protection, including Muffle furnace main body, the Muffle furnace main body includes
Heater 5 and the heating furnace 12 installed in the top of heater 5.Operating surface is installed on the housing of the heater 5
Plate 3, the top of the heating furnace 12 offers steam vent 1 and is provided with key switch door 2 in the sidepiece of heating furnace 12.
The Muffle furnace apparatus also includes exhaust gas processing device, and the exhaust gas processing device is including 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 heater 5
Burner hearth 12 selects light aluminum oxide ceramic fibre burner hearth.
In the present embodiment, the heat sink 8 is specially the internal casing that the aqueous solution is housed.The lower end of heat sink 8 leads to
Cross that appendix 6 is connected with steam vent 1, its top is connected by pipe fitting with the top of absorbent charcoal adsorber 9.The activated carbon is inhaled
The lower end of adsorption device 9 is connected with blast pipe 11, for further filtration, purification pernicious gas, under absorbent charcoal adsorber 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 absorbent charcoal adsorber 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.
In the use of the present invention, first, switching on power, the temperature control on inspection operation panel 3 after earth leakage circuit-breaker is opened
Display is then shut off earth leakage circuit-breaker whether in the range of 25-30 DEG C of room temperature；Then key switch door 2, inspection are opened
Look into whether heating furnace 12 has the sample not taken out or catalyst roasting debris, steam vent 1, and and gas transmission are opened in inspection after finishing
Pipe 6 is connected, and opens control valve 7, and be filled with into activated carbon adsorption bed ammonia, you can added into heating furnace 12 it is to be heated/
The material of burning, Muffle furnace main body is started working.The tail gas that the substance release of heating/roasting goes out in Muffle furnace main body is described
The process of exhaust gas processing device is as follows：
1) tail gas out enters heat sink 8 from steam vent 1 and carried out after cooling processing, subsequently enters activated carbon adsorption bed
In, the SO2 wherein in tail gas is first by the physisorption of activated carbon, and in the presence of O2 and H2O, SO2 further by
Catalysis, occurs to generate H2O4 and NH4SHSO4 after oxidation reaction, and be stored in the micropore of activated carbon；And NOx is in NH3 condition
Under, after the catalytic action of activated carbon surface, occur redox reaction generation N2.That is the change of the generation of activated carbon adsorption bed
Learn reaction as follows：
SO2+2H2O+O2 → H2SO4,
H2SO4+NH3 → NH4HSO4,
4NO+4NH3+O2→4N2+6H2O。
2) tail gas after exhaust gas processing device, SO2 and NOx gases clearance can reach 95% and 90% respectively；And
And after activated carbon adsorption bed is reaching saturation absorption, be sent in regenerating unit and carry 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 is except by SO2 in tail gas and NOx and entering
Row purification is outer, the noxious material such as volatile organic matter in tail gas can also be removed, while accessory substance H2SO4 and NH4HSO4 are entered
Row is recycled.
Explanation embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in this hair
Within bright protection domain.
