The invention discloses a kind of method of cement kiln synergic processing house refuse, it is characterized in that：House refuse is sub-elected into the materials such as metal using screening installation, then will be crushed in remaining house refuse input crushing system；The temperature that house refuse after will be broken is sent into disposal stove at 1000 DEG C~1100 DEG C by conveying equipment carries out incineration disposal, burn the raw material after the flue gas produced, cinder and pre- thermal decomposition and enter most final stage cyclone preheater together, gas enters mulitistage cyclone above and discharged after multiple gas solid separation after gas solid separation, and then clinker is made into calcining in rotary kiln in solid.Using the present invention, the ignition temperature disposed in stove is controlled at 1000 DEG C~1100 DEG C, ensure the poisonous and harmful substance that house refuse is fully burnt, thoroughly decomposed in house refuse, it is to avoid the formation of bioxin, realize the minimizing of house refuse, innoxious and recycling treatment.
Description
Technical field
The invention belongs to the preparation of the burning disposal of solid waste and cement, it is related to a kind of cement kiln synergic processing life rubbish
The method of rubbish, is particularly suitable for use in the effective disposal and beneficial utilization of house refuse.
Background technology
Due to the quickening of ur- banization speed, the yield of house refuse increasingly increases, the scientific and effective disposal of house refuse
It is the significant problem that we face at present.China's domestic waste total amount in 2013 is up to 1.8 hundred million tons, and national rubbish total amount is about
600000000 tons, by the end of the year 2011, China's domestic waste accumulating amount is up to 8,000,000,000 tons, and the phenomenon of garbage-surrounded city is increasingly serious.So
And, the disposal options such as traditional sanitary landfills, compost have the shortcomings that addressing is difficult, resource recovery is low, there is secondary pollution, rubbish
Rubbish burning electricity generation has that investment is high, dispose.With the increasing and sustainable development of environmentally friendly dynamics
Requirement, recycling economy with recycle just widely paid attention to, selection rationally effectively domestic garbage resource utilization side
Formula is increasingly paid close attention to by people.
Cement kiln synergic processing house refuse technology has the incomparable advantage of traditional life refuse disposal mode, at it
Put temperature high, gas and material are long in the high temperature section residence time, burning state is easy to stable, and high-temperature alkaline environment suppresses bioxin
Production, can curing heavy metal ion, fuel and raw material can be saved, cost of investment is relatively low.Also, at cement kiln collaboration
" minimizing, the innoxious, recycling " of rubbish can really be realized by putting house refuse, be proved to be a kind of by project practices at home and abroad
Reasonable effective disposal options.
During rubbish cooperative disposal, what harmfulness was maximum in terms of secondary environmental pollution is exactly bioxin.Suppress Er Evil
The generation of English needs incineration temperature more than 850 DEG C（Preferably more than 1000 DEG C）, flue gas has 2 s in stove（Or it is longer）'s
Residence time, flue gas has higher turbulivity, and ensures enough oxidizing atmosphere.
For the cement kiln synergic processing system of existing practical engineering application, mainly there is CONCH in the prior art
Kawasaki Kiln system systems（Abbreviation CKK systems）, hot plate furnace system and RDF technologies.
For CKK systems, single refuse gasification boiler is provided with, house refuse is introduced into gasification furnace, burns and produces
Flue gas enter dore furnace.But refuse gasification temperature is at 450 DEG C~600 DEG C, and the relatively low rubbish that easily causes of gasification temperature is in gasification
During produce bioxin.In addition, row enters back into feed proportioning system outside the lime-ash that gasification furnace is produced, and raw material together dispose by dispensing,
So easily cause the secondary pollution of heavy metal, bioxin etc..In addition, rubbish dosage or physicochemical property gasify when fluctuating
Easily occur flame-out phenomenon in stove, be that the generation of bioxin creates conditions.
For hot plate furnace system, hot plate stove is set between tertiary-air pipe and dore furnace, rubbish fires into hot plate stove
Burning may form stacking states in hot plate stove, cause house refuse fully to burn, local reduction is formed in hot plate stove
Atmosphere easily produces bioxin, the risk that there is secondary environmental pollution.
For making garbage derivatived fuel（Abbreviation RDF）Direct plunge into for dore furnace progress cooperative disposal, dore furnace is set
Meter and the temperature of operation are general at 850~880 DEG C, and the furnace gas residence time is shorter, also exists in stove a certain degree of
Reducing atmosphere.This all can not effectively be avoided the generation of bioxin, similarly there is the risk of secondary environmental pollution.
The B of the Chinese patent CN 104058614 and B of patent CN 104058615 set single waste incinerator, by cooling
The machine lingering remnants of past customs introduce incinerator carry out rubbish it is combustion-supporting, after burning high-temperature flue gas entered back into after boiler of power generation by waste heat dore furnace or
Person enters grate-cooler, but the system involved by the two patents is all transported to dispensing in the presence of being arranged outside the lime-ash produced after burning again
The situation for dispensing of standing, so easily causes secondary environmental pollution problem.
The content of the invention
The purpose of the present invention is intended to overcome that of the prior art not enough there is provided a kind of cement kiln synergic processing house refuse
Method.Using the present invention, house refuse is under oxidizing atmosphere in 1000 DEG C~1100 DEG C burnings, can effectively solve existing
It is relatively low because there is local reduction atmosphere, the insufficient, ignition temperature of house refuse burning in house refuse cooperative disposal（Existing point
Furnace gas temperature is solved at 850~950 DEG C）And the problem of be also easy to produce harmful substance bioxin；House refuse can be made full use of
Fuel value and material value realize the minimizing of house refuse, innoxious and recycling treatment.

Ensure house refuse in the environment higher than calciner temperature, rubbish fills in the sufficient environment of oxygen under fluidized state
Divided combustion, is not in the phenomenons such as accumulation, incomplete combustion, it is possible to prevente effectively from bioxin is generated；
（3）Using the present invention, most carbonate are decomposed in dore furnace, and a large amount of heat absorptions are not present in Disposal of Domestic stove,
Be conducive to preferably ensureing that rubbish is higher in disposal stove ignition temperature, and the material entered in disposal stove is essentially alkaline oxygenated
Calcium, the high temperature and alkaline environment can avoid bioxin from producing；Disposal of Domestic stove is arranged on behind dore furnace, can be kept away
Exempt from the disposal that carbonate mineral decomposes a large amount of heat absorptions in disposal stove and has influence on house refuse, more avoid giving birth in cooperative disposal
Caused secondary pollution hidden danger during rubbish living；
（4）Using the present invention, Disposal of Domestic stove is adapted to the burning of waste particles, while RDF burnings are also suitable for, and with
Traditional RDF directly enters dore furnace and compared, and its incineration temperature is higher, and in the absence of local reduction atmosphere；House refuse of the present invention
Cooperative disposal free of waste process, incineration residue directly enters the calcining that rotary kiln carries out clinker together with raw material.
