The carbonization slag charge that structure ejects is containing glass fibre, valuable metal and white carbon black, through dispensing, send smelting shop reclaim glass fibre,
Valuable metal and white carbon black；
4. thing is torn up by mixed gas produced after pyrolysis, containing CO2, CO, methane, HBr, lower aliphatic hydrocarbon, relatively low point
The aromatic hydrocarbons of protonatomic mass, phenol, methylphenol, bisphenol-A, bromophenol and two English；Under the effect of the first air-introduced machine (2), advanced
Enter expansion chamber group (3) heavy oil separation；Gained heavy oil passes through air-distillation pyrolysis oil, obtains light naphthar, heavy naphtha, light oil
Gas and 4 kinds of fractions of heavy oil gas；The high-temperature fraction with higher thermal value is sold as lower grade fuel oil；Hydrogenate and de-through appropriateness
Oxygen, the low temperature fraction Petroleum of processed and light petroleum gas can reclaim as gasoline and bavin main body of oil and use；
5. from afterbody expansion chamber gas out containing CO, methane and two English, a part enters waste heat boiler (4) as gas
Fuel combustion；Another part is as the fuel providing pyrolysis treatment apparatus (1) thermal source；In waste heat boiler (4), gas is at combustor
Oxygenation fully burns, and two English burn processing are fallen, and furnace temperature is up to 1000 DEG C-1300 DEG C；It is overheated to be produced by moisture film heat exchange
Water vapour drives turbine unit (10) generating；
6. the flue gas discharged from waste heat boiler (4), the flue gas naturally cooling to 180 DEG C through U-shaped air cooling pipe (5) enters pulse bag
Gather dust；Cool down taste removal in flue gas sends into desulfurization taste removal tower in the two poles of the earth under the effect of the second air-introduced machine (7) after gathering dust, pass through in tower
Water wash desulfurization, cool down, add sheet alkali arsenic removal, reach national environmental standard discharge；Washing water recycles.
