  The instructions of process of medical waste pyrolysis incineration system

  The process of this system: put medical waste in transient room through loading system into pyrolysis gasification incinerator, put around 6tons one time. Then close seal. When the temperature of the second burner up to 850℃,fire the waste on the bottom of the incinerator meanwhile bring air which is less than theoretical quantity(0.3-0.5),the long-chain organic compounds in medical waste will soon split as short-chain flammable gas (hydrocarbon, carbonic oxide , hydrogen)for anoxic environment. The flammable gas go into premixes and mixed with excessive air together into the second burner and proceed high temperature peroxide(excess air coefficient 1.8) so as to burn completely, thus the molecular structure of poisonous and harmful substance will be completely destroyed. After the reaction is discharging system. This item is two parallel furnace form (A and B) , when A incinerator is almost finished then B incinerator will be on fire and start pyrolysis, thus in steady operation, gas output is stable and can self ignition in pyrolysis process. Oil consumption in premixes can be ignored.

  The high temperature flue gas after incineration will go into the after heat boiler through cooling, so the temperature will be reduced to 550℃, then the gas will go into half dry quenching acid removal equipment be cooled down very quick as in one second the temperature will be changed from 550℃ to 200℃,meanwhile to wipe off the acid gas from flue gas to ensure there will be no gas dew in subsequent line and equipment. And the water spray inside half dry quenching deacidification tower will be completed evaporation, so there will be no mud and clod formed by dust deposition and also no more waste water go out. The spray water after being heated becoming water gas which will go into the back end equipment together with flue gas. Then spray carbon active and ground hydrated lime into the pipeline this absorbent will mixed with flue gas homogeneously and will be deposited in the bag of bag-type dust remover thereby become dust net, this net can absorb heavy metal, dioxin in flue gas and disacidify deeply. So through this way, the flue gas was de-dusted by bag-type remover and vent environmentally through chimney.
