Synchronous recycling method with high-calorific-value dangerous waste and municipal solid waste
The invention provides a synchronous recycling method with high-calorific-value dangerous wastes and municipal solid wastes, which includes following steps: (1) mixing dewatered sludge, building solid wastes and fuel residues from power plants according to the mass ratio of (3-5):(2-4):(1-3), and aging the mixture for 20-30 days to obtain a stacked material; (2) mixing dangerous wastes and homogenizing and crushing the dangerous wastes, anaerobic pyrolyzing the dangerous wastes at higher than 1500 DEG C for 1-2 h to obtain pyrolyzed gas and pyrolyzed residue, performing plasma gasification to the pyrolyzed gas at a temperature of higher than 5000 DEG C for 5-10 s to obtain artificial flammable gas; (3) water-quenching the pyrolyzed residue and mixing the pyrolyzed residue with the stacked material according to the volume ratio of 1:(60-80) uniformly, and performing granulation to obtain raw material granules; and (4) sintering and moulding the raw material granules and cooling the moulded granules to obtain a finished product of ceramic granules. The synchronous recycling method can reduce exploitation of primary energy resource and primary resources, can reduce damage on natural environment, is beneficial to maintenance and optimization of original ecologic system and can increase industrial benefit.
