Household garbage pyrolysis and incineration integrated device

Abstract

The invention discloses a household garbage pyrolysis and incineration integrated device. The household garbage pyrolysis and incineration integrated device mainly consists of a charge hipper, a pyrolysis rotary kiln, an incineration furnace and a tube type heat exchanger, wherein parameters such as a slenderness ratio, an angle of inclination, rotation speed and a pyrolysis temperature of the rotary kiln are designed, and parameters such as the shape, a furnace hearth temperature, a combustion chamber outlet temperature, a combustion chamber size and a fire grate area of the incineration furnace are designed. The parameters are designed, so that the size of an incineration room is relatively high in matching degree with the size of the rotary kiln, standing time, in the device provided bythe invention, of materials is moderate, and cracking reaction is complete.

Description

technical field [0001] The invention relates to a domestic waste pyrolysis and incineration combined device, which belongs to the field of waste recovery and recycling. Background technique [0002] With the development of the economy and the improvement of people's living standards, the output and removal volume of domestic waste is increasing, and it is expected to reach 200 million tons per year by 2020. Compared with the incineration technology, the domestic waste pyrolysis technology can effectively recycle the organic matter in the material, and has lower secondary pollution emissions and higher energy utilization rate, which is very suitable for small-scale distributed domestic waste in small and medium-sized towns deal with. In the pyrolysis treatment of domestic waste, rotary kilns are widely used in industry due to a series of advantages. However, the design of the rotary kiln, including the influence and effect of important parameters such as inclination angle, ...
