Biomass waste pyrolysis incinerator

Abstract

The invention discloses a pyrolysis incineration device for biological garbage. The pyrolysis incineration device comprises a fixed incinerator and a rotary incinerator. The rotary incinerator carries out ignition and thermal insulation through a fire pipe, carries out oxygen debt combustion on the biological garbage to generate sensible heat required for a pyrolysis process, carries out innocent treatment on the biological garbage and generates carbon-based materials. Combustible gas generated by pyrolysis and oxygen debt is introduced into the fixed incinerator through a pipeline so as to carry out oxygen replenishment and full combustion, an environmental-friendly high-temperature heat source is generated, and the dust emission generated by direct combustion of the biological garbage is reduced. The pyrolysis incineration device adopts a two-furnace matching structure and has the advantages of clear function allocation and stable and reliable equipment operation.

Description

technical field [0001] The invention relates to equipment for high-temperature pyrolysis and incineration of biomass waste to generate high-temperature heat sources and carbonized materials, in particular to a pyrolysis and incineration device for biomass waste. Background technique [0002] Domestic organic waste such as plastic bags and kitchen waste, and industrial organic waste such as straw, weeds, bark, sawdust, asphalt, and rubber are actually huge renewable resources. On the one hand, the harmless treatment of these domestic and industrial wastes and conversion into carbon-based organic fertilizers or carbonized materials have obvious economic and social values. On the other hand, during the conversion process, using the gaseous products of its high-temperature pyrolysis as a clean energy source for heat supply is also an important technical route for the development and utilization of renewable energy sources. [0003] But at present, for the treatment of these dom...

AI Technical Summary

Problems solved by technology

[0003] But at present, for the treatment of these domestic organic wastes and industrial organic wastes, most of them adopt the method of direct combustion, but the combustion efficiency of this method is very low, and the energy utilization is very limited, especially secondary waste such as smoke and tar will be produced. Pollution

The technology and equipment for carbonization are not ideal either. The traditional earth-steamed charcoal method is too inefficient and pollutes significantly; although the new external heating carbonization furnace solves the problem of mobility and operability, it consumes a lot of energy, especially Strict requirements on the shape and composition of organic raw materials

The pool-type carbonization furnace has the advantage of low cost, and the carbonization efficiency and adaptability to raw materials have also been greatly improved, but there are also problems such as continuous production, continuous feeding, and the need to extinguish the fire and cool down when the carbon is discharged.

[0004] The above-mentioned existing organic waste treatment equipment and methods all have obvious technical problems, mainly manifested in poor working environment, secondary pollution problems such as smoke, tar, etc.; The efficiency of incineration is very low, which restricts the development of this environmentally friendly renewable energy technology
