Waste enameled wire, namely furnace charge is crushed to 25-40mm through pulverizer, and rotary conveyor takes loading hopper 19 to, and star feeder is added the flue 1 of pyrolysis liquating furnace.Ring-type charging guide plate 6 guides furnace charge transmission direction, and enterprising tracheae 3 injects high-pressure air, and lower inlet duct 4 is channel of nitrogen, and high-pressure air and nitrogen are driven to central airway by outer wall, guarantees that in stove, furnace gas flows to central airway 2 by outer wall, and makes it to center heat transfer.
Pyrolysis oven heating adopts top to establish burner, discharge fume in bottom, heating and temperature control is at lower part outlet place 800-900 DEG C, indirectly enameled wire in flue 1 is heated, enameled wire pyrolysis output oil gas is discharged from flue 1 central airway 2 and is received top, furnace side second burner 13 through cross escape pipe 5, i.e. oil gas burner, and preheated air about 300 DEG C burning is joined in the effect via gas blower 21 and interchanger 17, two-stage natural gas combustion nozzle is established at middle part again, heats up and supplements not enough heat.Enameled wire through 3 meters of indirect heating, more than the 1 hour residence time, complete pyrolysis.
Tin, Aluminum-aluminum alloy furnace charge are heated to 800 DEG C, and liquate comparatively at the bottom of Beecher, can collect through hopper 9, and liquid discharge pipe 8 is established in exit, derive ingot casting, and the outage passed for liquid discharge pipe 8 can be established in the lower end of worm conveyor 24.Furnace charge is delivered to Material collecting box for harvesting 32 through two 8.6 meters of stainless steel spirals coolings.Temperature is down near ambient temperature, and copper can not be oxidized under the protection of gac.Furnace charge through broken selection by winnowing, isolate copper cash section, shot copper, through magnetic separator 35 deironing, the qualified high purity copper of output.The flue gas that the oil smoke of pyrolysis output and combustion of natural gas produce is in charge of 14 from bottom smoke evacuation, the house steward 15 that discharges fume drains into air heat exchanger 17, flue gas washing tower 26 is delivered to through induced draft fan 18 effect, then by Wingdale neutralization, coke adsorption treatment, via chimney 31 qualified discharge under induced-draft fan 30 acts on.
Waste enameled wire has paint, plastics, paper, greasy dirt, Deng organism, joint has tinsolder, disassemble and also may be mixed into aluminium wire, make paint, plastics, paper, greasy dirt pyrolysis by enclosed system, 200 ~ 300 DEG C, start pyrolysis, one-level, second-order kinetics mechanism is by diffusion control, and strengthening driveing oil gas can accelerated reaction.Technique is taked high-pressure air drive, be maintained reducing atmosphere, be unlikely to He Cheng dioxin, make furnace gas walk toward centre pilot pipe simultaneously, and heat is reached center.450 DEG C start unsaturated compound and produce, polymkeric substance hinge, form coke.Third order reaction belongs to Dynamics Controlling Model, and the higher reaction of temperature is faster.For obtain evacuate coke, fast reaction speed, simultaneously consider prevent dioxin from generating, control Heating temperature at 800-900 DEG C, even if You dioxin at high temperature 2 seconds with regard to decomposition combustion.Waste enameled wire is reaching 800 DEG C, can pyrolysis complete completely in 20 minutes, discharges oil gas, only has a small amount of coke to be attached to copper surface.Complete 800 DEG C of pyrolysis, aluminium wire 660 DEG C completely can liquate out, produce and ensure more than 1 hour time and Aluminum-aluminum alloy containing than its low-melting metal and alloy liquate thereof out, can be separated with main metallic copper (fusing point 1083 DEG C).Under reducing atmosphere, gather with metal liquid form.
Waste enameled wire pyrolysis produces oil gas (anoxic reducing atmosphere can not synthesize Dioxins) in enclosed system and discharges, 800-900 DEG C of tissue burning, Dioxins is complete decomposition combustion in 2 seconds 800 DEG C time, 1000 DEG C of perfect combustions in 1 second are decomposed, and are the most effective ways of current Dioxins harmless treatment.
Flue gas washing recirculated water, periodic cleaning settling pool throw out, throw out mixes with gravity collected ash, adds river sand cement making cement brick and makes pavement construction material, supplements part evaporation and throw out absorption consumption water, arranges outward without waste water.Waste enameled wire is leaded, tin and alloy thereof are the granular Separation and Recovery of block at pyrolysis liquate, becomes precious resources recycling, can not produce heavy metal contamination to environment.The gac that pyrolysis coking generates is the scavenging agent that golden production removes prussiate.And copper is the catalyzer of its reaction, but output is few, can focus on export trade.Suitable caliber is selected in air blast, and induced-draft fan 30 outlet establishes sound damper to reduce noise pollution.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
