Medical waste containing a large number of biological pollution of infectious objects, as a highly hazardous waste, must be harmless disposal. As the most safe and effective way to deal with, high temperature incineration has its irreplaceable advantages.
The medical waste incineration treatment system adopts vertical rotary pyrolysis gasification incinerator as the core equipment, equipped with high quality flue gas purification equipment, has the following characteristics:
* primary waste without missing experience high temperature combustion;
* the burning temperature is above 1100, burn in high temperature flue gas containing toxic organic compounds;
* features such as broken glass containers, metal products, etc.;
* exhaust gas, residue, sewage, fly ash to properly handle and discharge standards;
* no contact, no leakage, no pollution;
* the system running without interruption, thus avoiding the outfit, the material of the secondary pollution and frequent starting and shutdown temperature fluctuations caused by the excessive exhaust.
Medical waste incineration treatment process system mainly includes feeding, burning system, waste heat utilization and flue gas cooling, flue gas purification and other systems. All system parameters are measured and controlled by the instrument and the automatic control system to ensure the stability, economy and efficiency of the incineration process.
Medical waste by the special transport car sent to the centralized disposal center, the hoist and into the incinerator by hopper and the double roller feeder into the incinerator. Pyrolysis gasification incineration furnace from the top down, followed by drying and pyrolysis section, combustion section, combustion section and cooling section. Garbage in the pyrolysis and gasification furnace (pyrolysis furnace) through the drying, thermal decomposition and gasification. After pyrolysis and gasification, the residues continue to burn in the furnace. Burnout after coking like residue is at the bottom of the furnace for air cooling, the grate mechanical extrusion, broken into clumps with a 100 mm below the discharge to water seal groove of the bottom of the, after wet out discharge slag system.
Pyrolysis and gasification furnace to produce mixed flue gas in the second combustion chamber, the secondary air supplying oxygen, full combustion, furnace temperature control in 850 degrees centigrade, after high temperature flue gas after burning through the fire tube waste heat boiler heat energy recovery, the temperature dropped to 600 DEG C into the quench cooling tower water spray to 200 DEG C into the exhaust gas treatment system. Exhaust gas treatment system includes a semi dry except for the acid tower, bag filter and activated carbon points injection device, can effectively remove acid gases in flue gas, heavy metal group and dioxin like substances, treatment compliance after discharged into the atmosphere.
Main operating parameters
* the daily processing capacity: according to the need to change the production line, up to 845 tons / day treatment capacity;
* equipment year running time: not less than 8000 hours;
* all the gas treatment standards; * incineration efficiency: >99.9%;
* destruction removal rate: >99.99%;
* the residence time of the flue gas in the two combustion chamber: >2s;
* dioxin concentration: <0.1TEGng/Nm3
Industrial waste incineration
The system is also suitable for the incineration of solid industrial waste because of the burning temperature of up to 1100.
