Abstract

The invention provides a solid waste decoupling combustion device, a solid waste decoupling combustion system device and a combustion method of the solid waste decoupling combustion device. The combustion device comprises a shell, wherein the interior of the shell is divided into a feeding combustion channel, a flue gas mixed combustion channel and a flue gas afterflame channel which are sequentially communicated through partition plates in the material flowing direction, and the feeding combustion channel is divided into a preheating drying area, a pyrolysis gasification area, a semi-coke area and a burnout area in the material flowing direction; an air distribution device is arranged below the feeding end in the feeding combustion channel, and vent holes are formed in the outer wall of the side, close to the preheating drying area and the pyrolysis gasification area, of the air distribution device; at least one deflection baffle is arranged in the flue gas afterflame channel, and a rotary deflection flue gas flow channel is formed in the flue gas afterflame channel through the deflection baffles; and an air-smoke heat exchanger is arranged in the flue gas afterflame channel close to the outlet. Through the reasonable flue and air distribution design and the optimized combustion process, materials are fully combusted, and the combustion device has the advantages of being compact in structure, small in pollutant emission and the like.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and relates to a solid waste decoupling combustion device, in particular to a solid waste decoupling combustion device, a combustion system device and a combustion method thereof. Background technique [0002] Low calorific value solid waste includes industrial solid waste containing organic matter, sludge and various types of garbage. The components of this type of low-calorific value solid waste are complex and changeable, and there are many problems, such as high water content, many solid non-combustible components, difficult to decompose, difficult to ignite and difficult to burn out, etc., making the theoretical combustion temperature of this type of solid waste low and the ignition time Long, poor combustion stability, not easy to burn out. With the traditional combustion method, the flue gas contains a large amount of pollutants such as dioxins and tars that have not been fu...
