Superconducting pipe garbage cracking gasification furnace.
Background technique
The processing of domestic waste has become an important process of the energy, environment and socio-intangible asset development, becomes me
One important and pressing task of governments at all levels, state.
House refuse cracking gasification is to realize garbage decrement, innoxious, recycling advanced technology, at " garbage-surrounded city "
As today of public hazards, with cracking gasification technical treatment rubbish by the great attention of the Chinese government.
The cracking gasification of rubbish is placed on house refuse in one special equipment, under certain temperature and pressure,
Make organic matter and gasifying agent (such as water vapour and oxygen etc.) in rubbish occur sequence of chemical reaction convert garbage into for have CO,
H2、CH、CNThe imflammable gas such as Hm and CO2、N2The process of equal non-combustible gas.The garbage cracking equipment for gasification of standard is necessary
Have three conditions, i.e., balanced Pintsch process gasification furnace, suitable gasifying agent, by the heat that thermic load requirement supplies, three is lacked
One can not.Garbage cracking gasification is complicated a multinomial physics and chemical process, be rubbish and gasifying agent in high temperature and centainly
Pressure issues the biochemical complex process reacted and the organic matter in house refuse is transformed into imflammable gas, therefore is gasifying
In the process, there are strict requirements to the temperature in gasification furnace, pressure, gasifying agent, especially stable balanced reacting field is high
Temperature is the key that garbage cracking gasification.
Currently, China, which in garbage processing procedure, has, burns " gasification " rubbish using vertical heater, rubbish is substantially being burnt
It burns in furnace and burns, discharged in burning goes out volume of smoke, particulate matter, sour gas, uncombusted waste, heavy metal and micro organic compound
Object etc. generates a large amount of carcinogenic dioxin therewith, and the rubbish amount of simplifying is low, and lime-ash needs subsequent processing, cannot work continuously, running cost
With and fixed investment it is all very high.Also have using traditional pyrolysis furnace and handle rubbish, but existing traditional single layer furnace wall cracking
Furnace reaction zone does not have temperature balancing device, is not able to maintain the high moderate pressure of reaction zone relative equilibrium, so that pyrolysis furnace is difficult to connect
Continuous stablize generates fuel gas, and the generation of unavoidable flue gas, does not shield the deleterious molecular of lysate release to environment
Pollution.Especially traditional cracking furnace body is single tube single layer structure, and single layer furnace body heats in heater localized hyperthermia outside furnace body,
Radiations heat energy is conducted to the rubbish of local heating by single layer furnace body, axial long because garbage cracking furnace body diameter is big, single layer furnace body
By thousand degree of flame high temperature, temperature field results in the rubbish heating temperature in furnace along the inhomogeneities of furnace body axially and radially for part
Unevenly, hot-spot is formed, garbage cracking side reaction is generated, or even appears in furnace internal cause hot-spot and rubbish charing knot occurs
Burnt accident.In addition from input end, the temperature in advancing to outlet end is in decline state to rubbish always in single layer horizontal chamber furnace (oven) furnace, greatly
The temperature condition of cracking gasification is not achieved in part rubbish, highly impacts the efficiency of garbage cracking gasification, less economical.
Summary of the invention
It maintains cracking in-furnace temperature relative equilibrium, keep the suitable balanced high moderate pressure of rubbish in furnace, be to implement life
Rubbish living efficiently cracks gasification, prevents the necessary condition of the noxious materials such as dioxin pollution environment.
The present invention for above-mentioned traditional defect of pyrolysis furnace and the operating condition of pyrolysis furnace, design it is a kind of efficiently, safety,
The vertical vibrating high-temperature super-conducting pipe garbage cracking gasification furnace that expense is low, can work continuously is super using heater heating furnace body high temperature
The evaporation ends of conduit make the radiant heat of heater balancedly be conducted to the rubbish in pyrolysis furnace by high-temperature super-conducting pipe, generate heat
It is worth higher fuel gas, then its reuse is burnt, provides endlessly thermal energy for garbage cracking gasification and machine operation is dynamic
Power.The high-temperature super-conducting pipe poly- thermal property of evaporator section rapid phase transition, high-temperature superconductor under vibrating state is utilized in the cracking gasification furnace
Pipe heat shielding characteristic, high-temperature super-conducting pipe rapid thermal conduction characteristic, quickly thermal characteristics and working medium shakes dynamic quick backflow principle,
Conventional pyrolysis furnace is replaced with this vertical vibrating high-temperature super-conducting pipe garbage cracking gasification furnace, cracking temperature can be in entire pyrolysis furnace
Up to 800 DEG C or so, in the presence of gasifying agent water vapour, rubbish reaction speed can be made to accelerate, rubbish factor of created gase and fugitive constituent ease
