Title:
METHOD FOR ORIENTED PYROLYSIS OF COMBUSTIBLE WASTE
Document Type and Number:
WIPO Patent Application WO/2015/196688
Kind Code:
A1
Abstract:
Disclosed is a method for oriented pyrolysis of a combustible waste. The combustible waste is placed into a pyrolysis furnace, a gas replacement is performed on the pyrolysis furnace by inputting nitrogen to discharge air inside the pyrolysis furnace, with the nitrogen pressure in the pyrolysis furnace being maintained between 0.05 and 0.1 MPa, and heating is started to enter a pyrolysis state, wherein the combustible waste is subjected to different pyrolysis steps according to different pyrolysis requirements including: a step of obtaining pyrolytic carbon of the combustible waste, a step of obtaining pyrolytic tar of the combustible waste, and a step of obtaining a pyrolytic combustible gas of the combustible waste; and in the method of the present invention, the combustible waste is orientally pyrolyzed into an organic carbon, a high heat value fuel gas and tar by means of adjusting the pyrolysis temperature, pressure, and temperature rising rate and adding a catalyst using the heat value of the combustible waste, which greatly improves the utilization rate of combustible solid wastes. Since in this method, air is isolated, and the combustion of carbon and the volatilization of heavy metals and chlorine are reduced, the emission of dioxins is at not greater than 0.1 ng/Nm3.
