Description
Technical field
The utility model relates to garbage reclamations to utilize technical field, and in particular to a kind of garbage derivatived fuel thermal decomposition system
System.
Background technique
Solid waste including raw rubbish is that soil, water and the primary pollution source of atmosphere pollution, environmental improvement are answered
Start with from solid waste reducing and less disposal process pollutant emission.In terms of constituent, solid waste is all inorganic
The mixture of object and organic matter.Wherein inorganic matter is divided into metal and nonmetallic；Organic matter is usually divided into according to short-term corrupt characteristic
Hold perishable organic matter and is difficult to rotten organic matter.Solid waste after eliminating inorganic matter and perishable organic matter is main
It is made of plastics, fabric, rubber, bamboo and wood, paper etc., referred to as garbage derivatived fuel (being called RDF), is after coal, petroleum, natural
Forth generation green energy resource product after gas.Since last century mid-term RDF concept is born, people are unanimously in the money for exploring RDF
Source utilization technology, environmentally friendly, efficient, the versatile process that do not generally acknowledge so far.
It is all initially using coal-fired electricity in American-European countries to reduce and inhibit dioxin due to component is containing chlorine
The mode of burning is mixed using RDF by factory, also once had and rejects the way that chlorine-containing components prepare " cleaning " RDF in source, someone grinds again in the recent period
Study carefully the thermal decomposition gasification combustion technology of RDF.All explorations are all desirable in the same of energy to greatest extent or resource utilization RDF
When, and can be reduced or eliminate the pollutant emission of resource utilization process generation, the especially discharge of dioxin.
Although fire coal, which mixes burning, is able to solve partial contamination emission problem, while proposing higher requirement to RDF product, no
Then boiler system must be just transformed.RDF is low value resource, deep processing, and long distance transportation can all offset itself
Production by recycling bid value, fire coal, which mixes burning, only just can be used under the conditions of certain specific, be unable to get popularization.It rejects in source
Chlorine-containing components are that a kind of way to lose more than gain is eliminated substantially because commercial value is low.
So-called pyrolytic gasification is to allow RDF in the first combustor section under conditions of controlling oxygen concentration first in fact
Burning generates the flue gas containing combustible gas, and then flue gas burns in dual firing chamber's secondary high-temperature, has with the high temperature raising of second-time burning
Machine object destroys rate by fire, reduces the generation of dioxin.Still a kind of burning process in fact.Dust, oxysulfide, nitrogen oxides, two dislike
The discharge of the pollutants such as English can not be eliminated, and only discharge has lacked a bit, therefore, so far also without being that industry and the public are complete
It is complete to receive.
RDF thermal decomposition truly should be in the case where completely cutting off air conditions, and organic matter is warming up to point by indirect heating
Temperature or more is solved, the organic matter in RDF is allowed to occur the fracture of molecular link, the gaseous state small organic molecule of formation, with evaporation and raw
At hydrone form pyrolysis gas；The inorganic matter (ash content) and fixed carbon that RDF is mingled with form carbon slag.Pyrolysis gas is condensed collection
Afterwards, incoagulable combustible gas under pyrolytic behavior and room temperature is obtained；Pyrolytic behavior is made of high boiling point organic compound and water, can after water-oil separating
Stored, transported and utilized convenient pyrolysis oil.The combustible gas that room temperature can not coagulate generates after dedicated combustion chamber high-temp combustion
High-temperature flue gas for heating to pyrolysis reactor, fixed gas need not be stored, also not wasted, and entire pyrolysis does not need additionally to add
Heat energy.
Pyrolysis is not high to the morphological requirements of RDF, without forming, without excessively refining and drying, only consumes RDF energy itself
15%-20% full dose resourcable transformation can be realized, the energy of 80%-85% is kept down.Relative to burning, burning be through
Cross the small molecule fixed gas for only accounting for RDF organic component 15%-20% of purification, smoke discharge amount, dust, oxysulfide, nitrogen oxidation
The pollutant concentrations such as object all substantially reduce, and are emission reduction, environmental protection, efficient RDF disposal of resources technology.
So, how to ensure to completely cut off in RDF pyrolytic process air, guarantee that system is long-term, safe and stable operation；How to pacify
Entirely, high efficiente callback avoids shutting down caused by blocking because of pipeline and tower, accident occurs using the various components in pyrolysis gas；How
Pyrolysis oven production capacity is improved, to meet big industrial production needs；And improve pyrolysis system the degree of automation；Etc. all become mesh
Preceding urgent problem to be solved.
