Description
Technical field
The present invention relates to coking technology field, more particularly to it is a kind of using tamping coke furnace to containing low-order coal,
The technique that rubbish and the molding mass of biomass carry out coking.
Background technology
Since 18th century, coal turns into one of widely used energy of human world, with regard to China
Energy consumption structure for, current coal occupies 70% or so, is the national main energy sources depended on for existence.
According to the difference of structure and composition, coal is divided into lignite, bituminous coal and anthracite three major types, its metabituminous coal
It is divided into lower-grade metamorphic bituminous and mesometamorphism bituminous coal again, lower-grade metamorphic bituminous also referred to as ub-bituminous coal, itself and lignite one
Rise and be referred to as " low-order coal ".According to statistics, the reserves of China's low-order coal account for national explored coal reserves
More than 55%, up to 561,200,000,000 tons, but due to product of the low-order coal as incoalation initial stage,
With phosphorus content is low, moisture is high, it is easy efflorescence, easy spontaneous combustion, high fugitive constituent, immersion intensity difference, anti-dropping
The features such as intensity difference, thus the serious direct exploitation for limiting low-order coal, this undoubtedly causes huge
The big wasting of resources.In addition, increasingly increase and high-quality coal stock number with domestic energy demand
Fall sharply, upgrading conversion and the comprehensive utilization of low-order coal already turn into current China's energy research and exploitation
Major fields.
So far, the Upgrading Processes both at home and abroad for low-order coal are broadly divided into pyrolysis upgrading skill
Art, non-evaporating dehydrolysis upgrading technology and shaping upgrading technology three major types, wherein, for shaping upgrading skill
For art, low-order coal is in forming process, and the physical action such as high pressure or shearing is to its gel structure and hole
Slot sytem generates irreversible destruction, it is thus possible to inherently lifts the coal rank of low-order coal, makes it
Degree of coalification is also improved therewith, so that the dust for solving drying low-order coal is big, easily absorb water again, easily
In deficiencies such as spontaneous combustions.But current low-order coal upgrading technology is in experimental study and engineering initially should
With the stage, the equipment in the absence of its heavy industrialization is applied thus limit the exploitation of low-order coal
Utilize.
Biomass energy is that green plants converts solar energy into chemical energy and is stored in the energy inside biomass
Amount, i.e., using biomass as the form of energy of carrier, it directly or indirectly derives from the light of green plants
Cooperation is used, and can be converted into conventional solid-state, liquid and fuel gas, inexhaustible, nexhaustible,
It is a kind of regenerative resource, while being also a kind of unique reproducible carbon source.The biology researched and developed in recent years
Matter curing molding technology changes traditional mode of biomass energy utilization, and loose biomass is converted into
Highdensity shaped fuel, directly burns or as gasification, liquefaction raw material, as biomass energy exploitation
A kind of effective way utilized, is also the effective ways for substituting conventional energy resource, Unfortunately, mesh
It is preceding not possess the equipment for applying biomass fuel heavy industrialization still.
There is the garbage compost work carried out at present in China for the recycling mode of house refuse at this stage
Skill and the garbage derivatived fuel technology studied, wherein for garbage derivatived fuel technology, though
The right technology has obtained commercial application in day, moral, Mei Deng developed countries, but because China is current
Do not possess the separate waste collection system of specification still, so the external sorting rubbish stable for component
Fuel manufacturing technology can not be applied to the high humidity composting of China, therefore, should be directed to the rubbish of China
Rubbish reclaims present situation, and design research and development are adapted to the process for treating garbage as resource of China's national situation.
Tamping coke furnace is the maximization equipment used in the coking process of coal, and its floor space is wide, investment
Capital cost is big.Coking of coal be by raw material of coal through high-temperature retorting produce coke, while obtain coal gas,
Coal tar and a kind of coal conversion process for reclaiming other chemical products, its coke product are mainly metallurgical coke
Or chemical industry is burnt.Due to industrially very high to the quality requirements of this kind of coke so that production metallurgy is burnt or changes
The coal raw material that work Jiao is used is mainly coking coal, 1/3 coking coal, bottle coal, rich coal, lean coal, meager lean coal
Etc. coal, belong to mesometamorphism bituminous coal, but the shortage of coal resources in recent years, particularly for coking
The reduction of the middle high-quality coal raw material of industry so that the cost of material of coking industry is growing day by day, in addition
Steel, metallurgy etc. were a large amount of in recent years needs the decline of metallurgical coke or the burnt industry of chemical industry, causes coke to produce
The demands of product is reduced, price declines, so as to force coke-oven plant drastically to reduce coke output, thus band
Come consequence be that tamping coke furnace is out of service, once and coke oven disable will scrap, then in order to protect
Furnish a huge amount of money for the tamping coke furnace equipment invested to build, would have to maintain the operation of coke oven in minimum level, this
Sample not only reduces the availability of tamping coke furnace, can also cause the production capacity surplus of coking industry.Therefore,
The coking industry for being on the verge of negative growth how is saved, the availability of tamping coke furnace is improved, coking industry is solved
The problem of production capacity surplus, has turned into the bottleneck of current containment coking industry development.
In summary, how tamping coke furnace is applied to low-order coal, rubbish under current situation
It is puzzlement this area skill with the exploitation field of biomass so that above mentioned problem is all readily solved
The technical barrier of art personnel.
The content of the invention
Present invention solves the technical problem that being to overcome prior art can not realize low-order coal, rubbish and life
The problem of defect of material energy large-scale application and low existing tamping coke furnace availability, and then provide one
