As shown in figure 3, tunnel oven of the invention, further includes de-waxing exhaust processor 4, de-waxing exhaust processor 4 includes phase
Coagulation device 41 and secondary processor 42 even is provided with the chilling pipe 411 with quenching device 415 in coagulation device 41
And connect with the first normal temperature water pipe 412, the upstream end of chilling pipe 411 is connected with exhaust output tube 413, under coagulation device 41
End is connected for anxious cold liquid outlet and with solvent recovery with paraffin pond 414；Gas flare 421 is plugged in secondary processor 42 and with second
Normal temperature water pipe 422 is connected, and the lower end of gas flare 421 is immersed in the normal-temperature water in secondary processor 42, secondary processor
42 exhaust outlet is connected with chimney 5；It is connected between coagulation device 41 and secondary processor 42 by delivery pipe 43, delivery pipe 43
On gas-liquid separator 44 is installed, the gas flare 421 in the end connection secondary processor 42 of delivery pipe 43.
The gas discharge outlet of gas-liquid separator 44 is connect by pipeline with gas flare 421, and liquid outlet is connected to
Collector 45 is simultaneously input to secondary processor 42 with normal-temperature water jointly；Bubbling pipe 423 is provided in secondary processor 42.
The working principle of de-waxing exhaust processor 4 is as follows:
Coagulation device 41: the mechanical devolatilisation (exhaust gas) to come from de-waxing technique passes through level-one chilling Immersion treatment first
Device, Ban≤30 DEG C normal-temperature water (mono- entered in the processor), exhaust gas is entered in quenching device 415 by chilling pipe 411, portion
Dividing wax steam coagulation, the liquefaction of part oleic acid, chilling liquid is discharged by the pulse of bottom pulse valve, and relief liquor can recycle solid state wax,
It is recycled in solvent recovery with paraffin pond 414, part oleic acid liquid is collected and reused.Remaining gaseous state exhaust gas passes through after chilling liquid from level-one
It is discharged at the top of processor 41, gas-liquid separator 44 is set in delivery pipe 43, the moisture taken out of, which is separated, to be sent to secondary processor
42 recycle.
Secondary processor 42 uses submerged combustion, from coagulation device 41 come out gases Jing Guo gas-liquid separation into
Enter into second level submerged combustion processor, which substantially belongs to organic matter, in energy-efficient submerged burner sufficiently
Burning, such as following equation is a certain form of wax, and carbon dioxide and water are generated after burning:
C25H32+33O2→25C02Ten 16H20 (a kind of form of wax)
In exhaust gas the combustion process of other organic matters with it is upper similar.
To keep discharge efficiently up to standard, the gas after burning is adsorbed by 42 water-bath of secondary processor (normal-temperature water)
In addition coagulation device 41 plays double insurance for taste removal.Submerged burner is (useless using small flow natural gas mechanic diffusion formula burner
Air burner 421), energy conservation.Exhaust gas after two stage treatment enters the natural excrement of chimney 5.
As shown in figure 4, for the connection schematic diagram of de-waxing exhaust processor 4 of the invention and kiln basis 1.Coagulation device
41 are connected with the blower of the firing section of tunnel oven, and exhaust gas is discharged into quenching device 415 and is handled；It gives up in secondary processor 42
The heat that air burner 421 generates, can also be by the de-waxing section 11 or/and pre-heating temperature elevation section 12 of pipeline to kiln, with section
Save the energy.
