Description
Technical field:
The invention belongs to building materials field, relate to a kind of cement clinker production, relate in particular to a kind of full waste residue low temperature and sharply calcine cement of high index grog method.
Background technology
Generated by polyvinyl chloride by calcium carbide technology mainly is through water and calcium carbide reaction; Produce acetylene gas; Acetylene have " organic chemical industry's mother " laudatory title; It is one of most basic raw material of organic chemical industry's product in the world at present; But generated by polyvinyl chloride by calcium carbide production process; One ton of PVC of every production will produce 1.6 tons of carbide slags; Produce 25 tons of carbide slag slurries simultaneously; Expect the end of the year in 2011, China's generated by polyvinyl chloride by calcium carbide output will break through 1,000 ten thousand tons, will produce calcium carbide waste slag more than 1,600 ten thousand tons every year; Produce 2.5 hundred million tons of carbide slag slurries simultaneously; Handle by traditional landfill method, not only need increase the huge investment that the carbide slag transportation is buried, the more important thing is to cause environment to seriously influence.
In outdoor stacking, the wastewater from acetylene slag of formation is strong basicity, high suspended matter waste water to carbide slag, also contains hazardous and noxious substances such as sulfide simultaneously as for a long time, and many index is violated discharging standards.After the direct discharging of waste water, wherein suspended substance produces deposition in course of conveying, can cause line clogging, directly causes the riverbed to silt up.
Acetylene sludge wastewater PH is 12-14, and sulfides from wastewater exceeds standard, and changes but work as environment water PH, when being neutrality or subacidity, will cause a large amount of hydrogen sulfide to escape.In addition sulfide enter behind the river course bacterium participate in down with river in the dissolved oxygen reacting generating salt, exhaust dissolved oxygens a large amount of in the water, cause the hydrocoles mass mortality, water body turns black smelly.Carbide slag is stacked and to be taken a large amount of soils in addition, piles up seriously to land invasion for a long time, and the carbide slag water ratio surpasses more than 50%, is starchiness, and easy to leak pollutes the road surface in transit.
So generated by polyvinyl chloride by calcium carbide will develop, must solve this difficult problem of a large amount of waste residues that produces in the production process around the industry development sound development, this is the key of generated by polyvinyl chloride by calcium carbide industry Sustainable development.The drying acetylene technology is the novel acetylene generation technique that progressively develops in recent years, and its reaction water loss only is about 20% of a wet method acetylene, and the carbide slag of generation is moisture about 5%, the generation of having stopped carbide slag slurries, and water-saving result is remarkable.Simultaneously, because the carbide slag water ratio that produces is low, for development carbide slag new type nonaqueous cement technology provides condition, many in succession research and development institutions and enterprise have carried out concentrated research and development to its gordian technique and have captured.
A kind of dry discharging carbide slag slag 100% that discloses of Chinese patent 200810072854.5 substitutes natural stone grey matter raw material for producing cement chamotte processing method; With the carbide slag is main raw material; Adopt kiln to decompose the method for producing cement clinker outward; Its proportioning raw materials is that carbide slag 71.8-77.8%, sandstone are 8%-12%, sulfate slag 1.5-2.5%, flyash 11.2-15.2%; This method substitutes natural stone grey matter raw material for producing cement chamotte with carbide slag 100% and has solved the few problem of carbide slag consumption, and a large amount of pollution waste residues is turned waste into wealth.But carbide slag is an elaboration calcareous raw material of producing cement clinker in this method, in the carbide slag generative process, can produce a series of calcareous waste residues such as lime rock ballast, lime mud, calcium carbide collected ash, and collocation is not disposed, and also can cause certain environment to pollute; Secondly, during sandstone 8%-12% high silicon ingredient, because sandstone crystallization SiO
2Difficult tribulation is burnt, and the power consumption coal consumption is high, and output, quality will reduce, and cause chemical matching problem to calcining process; Three, this method prescription can cause preheater outlet spent air temperture high in process of production, causes system's skinning, and fault is many.
As everyone knows; Carbide slag 100% substitutes natural stone grey matter raw material for producing cement chamotte and produces solid phase reaction at preheater; 850 ℃ of dore furnace temperature of lower; 960 ℃ of upper temps; Go out 930 ℃ of material quick heatings of three grades of preheaters; Liquid phase appearance early; There has been grog to burn till three grades of porch; Frequent jams tremie pipe and preheater; 750 ℃ of secondary outlet temperatures, one-level heater outlet temperature are at 680 ℃, and it is fast to cause calcium hydroxide to decompose; Make the one-level preheater produce 22% calcium carbonate back reaction, 1.5%CaCO is arranged
3Back reaction gets into high-temperature blower and adheres to blade, causes the blower fan vibrations big, and bearing heats up high, can't run well.Secondly, the siliceous raw material sandstone is a crystalline silica, goes out just can transfer chemical combination SiO to after decomposing furnace is gone into kiln
2A large amount of calcium oxide do not have corresponding many active SiO
2The reaction, can only with the CO in the waste gas
2Form reversed reaction, add the water vapour of chlorine, sulphur, potassium, sodium and 18%, cause the preheater skinning to stop up, kiln ventilation is not smooth, and the flame retraction burns out kliner coating, kiln brick, and operation factor is low, phenomenons such as the frequent generation of equipment failure.
The installation method of a kind of calcining cement by carbide slag replacing whole limestone that Chinese patent 200720098247.7 is announced; The feeding mouth that the import that it is characterized in that being first and second grades of cyclone preheaters connects airduct connects material distributing valve through emission of baiting chute respectively; Raw material advance secondary respectively, " high-temperature calcination, middle temperature are decomposed " carried out in three grades of cyclone preheater outlets, and this method has solved the first class outlet temperature problem of too.But have following deficiency, one of which, first class outlet temperature if adopt oven dry wet slag efficient better, adopt dried slag temperature out still high at 550 ℃, and hear rate is wasted big; Its two, the main effect of the whole replacing lime stone of carbide slag decomposing furnace be the calcining sandstone since sandstone in crystallization SiO
2Be converted into chemical combination SiO
2The calcium oxide active passivation slower, that carbide slag is decomposited, the kiln body of having to extend increases process complexity, causes equipment failure many.
Also announced a kind of method in the document, Jin Yanyu etc. write utilizes waste residue low temperature calcination high grade variation grog [J] " Chinese cement " in April, 2011.It is poor that this technology has solved clinker strength; Problems such as burn-ability is bad; One-level cyclone preheater outlet temperature is reduced to 600 ℃ for 680 ℃; The back reaction minimizing absorbs through drying tube suspension raw material again, and the high-temperature blower impeller has been eliminated skinning, and clinker strength improves about 10MPa; Coal consumption reduces; But, still to adopt 5% efflorescence sandstone batching in one of which, this method, cause each oxide to decompose, dewater, can not overlap with solid phase reaction; Two, do not consider that the lime rock ballast can reduce one-level cyclone temperature significantly, it decomposes slow than carbide slag, and this part calcium oxide passivation time weak point is in kiln and C relatively
2S is swift in response and forms C easily
3S, this part lime mud is the raising the output part, more can reduces coal consumption on the contrary; Three, also have 300 ℃ of waste heats to lean on to increase spray painting to wet and reduce, be roughly equal to the 650kJ/kg calorific value, account for the 24% not utilization of burning till hear rate; Four, waste heat boiler reaches 600 ℃ and locates easy skinning.Its five, what rely in the method is thermal activation and chemical activation principle, occurs wild effect in operation easily; Six, with the siliceous raw material drift-sand by weight 11% proportioning change 5% efflorescence sandstone into; Rest part is replenished by slag and flyash; The decomposing furnace coal consumption descends significantly; Calciner temperature control drops to 800 ℃-850 ℃ by 850 ℃-900 ℃; Advancing three grades of preheater temperature is 870 ℃, and going out three grades of preparatory actuator temperatures is 860 ℃, goes out 730 ℃ of the preparatory actuator temperatures of secondary; Go out 600 ℃ of the preparatory actuator temperatures of one-level, wherein waste gas is by 300 ℃ of spray humidification coolings.But, because the high reversed reaction of temperature is not eradicated and spray water is mixed sticking often wall, reach certain thickness and smash the awl end from high falling, producing leaks out influences ordinary production.
In sum; Solved this problem of carbide slag in the existing technology; Fail to solve but be used for the above-mentioned shortcoming that cement production process exists, provide a kind of stable continuously, cost is low, utilization rate of waste heat is high cement clinker production is that the sector is thirsted for the problem that solves.
