The present invention belongs to the technical field of the incinerator equipment, and particularly relates to a small-scale
domestic waste incinerator and a using method thereof. The incinerator includes a
drying pyrolysis chamber and a
combustion chamber arranged over a grate
assembly of the waste incinerator, a secondary
combustion chamber is in communication with the upper portion of the
combustion chamber, a position in proximity to the upper portion of the
combustion chamber is provided with a
pyrolysis gas
nozzle, a
drying pyrolysis chamber outlet
flue duct with an induced draft fan is installed at a position in proximity to the upper end of the
drying pyrolysis chamber, the drying pyrolysis chamber outlet
flue duct is in connection with a pyrolysis gas
nozzle through a condenser, a diversion chamber is situated between the same side of the
combustion chamber and the secondary
combustion chamber and the drying pyrolysis chamber, and the drying pyrolysis chamber is longitudinally provided with a
flue gas
nozzle, which is in communication with the diversion chamber. A secondary combustion chamber outlet flue and a circulating flue are arranged at the top of the secondary combustion chamber, the circulating flue is in communication with the diversion chamber, and a guide plate configured to regulate the quantity of the
flue gas is arranged at the top of the secondary combustion chamber. In the present invention, the
moisture content of the waste entering the incinerator is reduced, the heat value for the waste is increased, so that the requirement of 850 °C for at least 2 seconds in the incinerator can be satisfied without supplementing fuel, and the homogenization of the waste is completed before entering the furnace, which ensures that the temperature and the load fluctuation of the incinerator is relative little, the
waste combustion is sufficient, and the ignition loss of the slags is low.
