The anaerobic low-temperature continuous pyrolysis process of urban and rural domestic waste is used to treat urban and rural domestic waste harmlessly and resourcefully. On the basis of harmlessness and resource utilization, stabilization and reduction treatment are achieved. Domestic waste generated after pyrolysis treatment Inert solid carbon residue, pyrolysis fuel oil, bio-natural gas. Among them, solid carbon residue is sorted and some metals are recovered. The remaining carbon residue has many comprehensive utilization directions and good economic benefits; pyrolysis fuel oil is recycled for industrial fuel or personal use; bio-natural gas is used for pyrolysis equipment after dechlorination and purification. Circulating heating energy can meet more than 60% of its own energy self-sufficiency. After pyrolysis treatment, the mass reduction rate of domestic waste is higher than 50%, the volume reduction rate is higher than 90%, and carbon emissions can be reduced by 0.4-0.7 tons per ton.

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.
