Abstract
The invention discloses a conversion furnace for the reutilization of combustible materials, which comprises a framework, wherein a cylindrical furnace body is mounted on the framework in a tilted manner; a supporting roller device and a furnace body rotating drive device are mounted between the cylindrical furnace body and the framework; the framework is fixedly provided with a material inlet and gas outlet device and a gasifying agent inlet device; and since the whole cylindrical furnace body is rotary and is tilted, materials can move in the vertical direction based on gravity in the cylindrical furnace body, so that the layer of the materials has good gas permeability, and coal gas can rise smoothly, thereby avoiding the bias burning phenomenon. Since the whole cylindrical furnace body is rotary and is tilted, the conversion furnace has the following advantages: 1,after being molten, plastics and other materials in wastes are continuously wrapped by slag of other wastes, thereby avoiding the adhesion phenomenon, ensuring that the materials move smoothly and the slag is discharged smoothly, preventing the furnace blocking phenomenon and realizing a stable and continuous gasification process; and 2, the lower wastes a bear lower pressure from the upper wastes, and the layering of the wastes is dynamic and variable, thereby ensuring that the gas permeability is very good, the reaction is stable and quick and the gas production efficiency is extremely high.
Description
Technical field
The present invention relates to a kind of device that combustiblerefuse, agricultural stalk the like waste are carried out resource utilization conversion, relate in particular to a kind of conversion stove with combustiblerefuse, agricultural stalk the like waste resource utilization, innoxious and minimizing.
Background technology
Along with the progress of society, sustainable development becomes the human target of pursuing.Rubbish becomes the burden of the earth as the product of mankind's activity, also becomes the serious hindrance that hinders human social development.Whole world rubbish average annual growth is 8.42%, and Chinese rubbish rate of increase reaches more than 10%.4.9 hundred million tons of rubbish of the annual generation in the whole world, only China just produces nearly 1.5 hundred million tons of municipal wastess every year, and Municipal Solid Waste in China accumulation volume of cargo in storage is huge.
The treatment process of rubbish mainly adopts landfill method, burns and send out and three kinds of processing modes of Unareobic fermentation now.
1, landfill method
Landfill method is to use maximum waste disposal methods, allows rubbish reach steady state through long-term physics, chemistry and biological action, and shortcoming is to have foul smell to produce, refuse landfill is away from the urban district, trucking costs is larger, and selection of land is subjected to more restriction, causes easily earth's surface and groundwater pollution.Especially serious is: can't degrade in the short period of time behind the landfills such as the plastic waste in the rubbish, waste chemical fiber, waste rubber, and degradable centuries even the more than one thousand years of needing is quite serious and extremely remote to the harm of environment at all.
2, burning method
Burning method is that rubbish is sent in the incinerator, oxygen carries out violent chemical reaction in combustiblecomponents in the rubbish and the air, and the advantage of burning disposal is that decrement is effective, and the residue volume after the burning reduces more than 90%, weight reduces more than 80%, processes comparatively thorough.Shortcoming is to destroy resource, rubbish contains the moisture about 70%, the water-bearing organic consumed energy, combustiblerefuse releases energy, and consumed energy offsets with releasing energy in burning process, dump energy seldom or be negative energy, therefore refuse thermal value there is requirement, will consumes coal, the combustion-supporting energy of wet goods in the burning, wasted a large amount of recyclable resources, and can form Dioxins when burning, easily cause atmospheric pollution.
3, Unareobic fermentation is the novel method of processing municipal wastes, but be to be a kind of effective ways of the energy with anaerobism garbage conversion in the rubbish, but its shortcoming is: all need to carry out the classification of rubbish before the processing, this is the maximum bottleneck of restriction refuse treatment, inorganics in the rubbish such as glass, metal, plastic waste, waste chemical fiber, waste rubber etc. can't participate in anaerobic reaction, cause the significant wastage of resource, and refuse classification difficulty, decrement is less, processing cost is huge, process not thorough, can't large-scale promotion application.
Prior art also have adopt producer gas generator or similar devices with combustiblerefuse destructive distillation carbonization changing into the technical scheme of inflammable gas, but often factor of created gase is low, the operation troubles rate is high.Trace it to its cause, the firstth, component of refuse is complicated, and bed permeability is bad, and coal gas rises and is obstructed, and the coal gas of generation participates in again burning, causes easily inclined to one side burning; The secondth, rubbish is varied, easily slagging scorification, and after temperature surpassed 200 ℃, the plastics in the rubbish etc. will melt adhesion, no longer move downward, and make gasification unsustainable; The 3rd is the pressure that the rubbish of lower floor also will bear upper strata rubbish, and ventilation property extreme difference, burning zone are difficult to blaze up and extinguish easily, makes the gasification difficulty.
