The operation principle of de-waxing exhaust processor 4 is as follows：
Coagulation device 41：The mechanical devolatilisation (waste gas) to come from de-waxing technique, passes through one-level chilling Immersion treatment first
Device, normal-temperature water (mono- Ban≤30 DEG C entered in the processor), waste 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 reclaim to solid state wax,
It is recycled in solvent recovery with paraffin pond 414, part oleic acid liquid is collected and reused.Remaining gaseous state waste gas by after chilling liquid from one-level
The top of processor 41 is discharged, and sets gas-liquid separator 44 in delivery pipe 43, the moisture taken out of, which is separated, delivers to secondary processor
42 recycle.
Secondary processor 42 uses submerged combustion, and the gases come out from coagulation device 41 Jing Guo gas-liquid separation enter
Enter into two level submerged combustion processor, the waste gas substantially belongs to organic matter, in energy-efficient submerged burner fully
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 waste gas the combustion process of other organic matters with it is upper similar.
To make discharge efficiently up to standard, the gas after burning is adsorbed by the water-bath of secondary processor 42 (normal-temperature water)
In addition coagulation device 41 plays double insurance for taste removal.Submerged burner is (useless using low discharge natural gas machinery diffusion type burner
Air burner 421), energy-conservation.Waste gas after two stage treatment naturally drains into chimney 5.
As shown in figure 4, de-waxing exhaust processor 4 and the connection diagram on kiln basis 1 for the present invention.Coagulation device
41 are connected with the blower fan for burning till section of tunnel cave, and waste gas is discharged into quenching device 415 and handled；Given up in secondary processor 42
Heat caused by air burner 421, 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.
