In view of the special characteristics of the shape of medical waste, the principle of waste pyrolysis and gasification is adopted. The waste is pyrolyzed and gasified under oxygen-deficient conditions in the pyrolysis furnace. The gas temperature in the pyrolysis furnace is controlled at about 200~400°C, and the center temperature of the slag can reach At about 850°C, organic waste is converted into combustible components such as CO and CH4, as well as inorganic water vapor, acidic gas and slag. After the combustible gas enters the mixing chamber, it is strongly mixed with the tangentially entering air and then sent to the secondary chamber for combustion. The flue gas temperature at the outlet of the secondary chamber can reach 850-1100°C, and the flue gas residence time is more than 2 seconds. The organic matter in the flue gas is completely burned. The operation of the pyrolysis furnace and the secondary combustion chamber implements integrated control, which not only ensures the safe combustion of waste but also fully stimulates the heat of the waste itself, reducing operating costs.
