Description
Technical field
The utility model relates to the use of the flue gas displacement apparatus that cement kiln cooperates with refuse disposal system, particularly a kind of cement
The device of kiln cooperative disposal house refuse exhaust gas volumn equivalent displacement.
Background technology
As the improvement of people's living standards, the discharge of house refuse is also more and more.At present, China's domestic waste
Volume of cargo in storage is occupied cultivated land 500,000,000 square metres up to 6,000,000,000 tons of, and 200,000,000 tons of domestic wastes are produced every year, will also be with 9% speed
It is swift and violent to increase.The house refuse of these substantial amounts constitutes the prestige being on the rise to city and greenbelt ecological environment
The side of body.Traditional waste disposal method has landfill method, composting process and burning method, and Urban Garbage Treatment in China is started late, main at present
Will be based on sanitary landfills.It is few due to there is treating capacity although establishing waste incineration and power plant in some cities, processing
Process is along with harmful gas (bioxin), sewage (percolate), the emission problem, rubbish such as waste residue (content of beary metal high)
Rubbish burning method still suffers from certain dispute at present.Relevant expert just once appealed that China will inhale in the process problem of municipal refuse
Receive the Japanese eighties and popularize garbage incinerating power plant, do one's utmost to solve the experience and lessons of secondary pollution at present again, conscientiously study and exert
Power realizes " minimizing, innoxious, recycling " processing of municipal refuse.Manufacture of cement unique production technology (alkaline qi leel,
More than 1000 DEG C of high temperature) provide excellent condition, the life of overseas utilization cement kiln synergic processing for processing domestic waste
The existing nearly 30 years history of rubbish living.Using cement kiln collaboration processing domestic waste, one is available with cement firing system
Clear up the foul smell and noxious material in rubbish storage and burning process；Two be that the lime-ash that waste incineration is produced can be as cement raw
Noxious material in material or mixing material, rubbish can resolve into corresponding inorganic matter and heavy metals immobilization in clinker；
Three be the part high-temp waste gas that produces of quality coal in cement kiln systems can as waste incineration supplemental heat source or whole thermal source, make rubbish
Burning process it is more abundant, further reduction even eliminate bioxin discharge.Realize " the innoxious, money of garbage disposal
Source ".
In present published patent in involved technical scheme, majority draws the heat smoke produced in waste incinerator
Enter cement kiln dore furnace and carry out secondary burning decomposition, or be divided into after combustible and noncombustibles will be flammable by rubbish progress pretreatment
Burned in thing feeding kiln.The clinker that waste incineration is produced then more is used as cement raw material or cement mixture progress recycling profit
With.However, due to the characteristics of municipal refuse existence and stability is poor, calorific value is low, moisture is high, exhaust gas volumn that waste incineration is produced is big,
Oxygen content is low, introduces the just conventional wind that rotary system is have impact on after cement kiln dore furnace, have impact on the combustion of dore furnace fuel
Burn, the Yield and quality and stability of cement kiln is not greatly lowered freely in ventilation.
Utility model content
In order to solve the above-mentioned technical problem, a kind of cement kiln synergic processing house refuse exhaust gas volumn equivalent displacement is provided
Device, it draws flue gas in the kiln of the hot flue gas equivalent of waste incineration with entering kiln tail smoke-box by blower fan from kiln tail smoke-box
Into boiler, it is ensured that air quantity is steady in kiln, it is to avoid influence to kiln system.
A kind of device for cement kiln synergic processing house refuse exhaust gas volumn equivalent displacement that the utility model is provided, including：
Grate furnace, kiln tail smoke-box, dore furnace, boiler and blower fan, the grate furnace are connected by the first pipeline with the kiln tail smoke-box, institute
State dore furnace to be arranged on the top of the kiln tail smoke-box and connect with the kiln tail smoke-box, the kiln tail smoke-box passes through second pipe
Connected with the boiler, the blower fan is arranged on the pipeline of the boiler export and passes sequentially through the boiler, described second
Pipeline, the kiln tail smoke-box and first pipeline are connected with the grate furnace, and the blower fan is used to control flue gas in above-mentioned dress
Circulation in putting.
Further, the cross section of first pipeline is square-shaped or toroidal.
Further, the cross section of the second pipe is square-shaped or toroidal.
In summary, a kind of device of cement kiln synergic processing house refuse exhaust gas volumn equivalent displacement of the utility model is with showing
There is technology to compare to have the advantage that as it is drawn and the waste incineration into kiln tail smoke-box by blower fan from kiln tail smoke-box
Flue gas enters boiler in the kiln of hot flue gas equivalent, it is ensured that air quantity is steady in kiln, it is to avoid influence to kiln system；Rubbish
Processing does not influence the Yield and quality of kiln：Using gas displacement technology, the flue gas that incineration firing is produced enters after kiln tail smoke-box,
Add 60% gas flow, to avoid the influence to kiln system, from kiln tail smoke-box by the high-temperature flue gas entered out of kiln draw
60%, equivalent displacement is carried out, the balance of kiln system air quantity is maintained, it is to avoid influence to kiln system；At rubbish harmful components
Manage thoroughly：Burn the high-temperature flue gas produced and enter rotary kiln smoke-box, dore furnace by the harmful substance in flue gas in high temperature
Environment is by the thorough resolution process of harmful substance (especially to effective processing of dioxin).
