Abstract
The invention relates to a device for preparing a cement water reducing agent by a physical method. Flyash is taken as a raw material and moves in a friction charged pipeline to rub with the pipeline wall, coal particles in the flyash lose electrons and carry positive charge, decarburized coal ash obtains electrons with negative charge, most coal particles with the positive charge move to a negative high voltage electrode plate and most decarburized coal dust with negative charge moves to a positive high voltage electrode plate under the action of an electric field when passing through a high voltage electrostatic separation cavity, and the flyash is separated into the coal particles, middlings (a mixture of the coal particles and the decarburized coal ash) and the decarburized coal ash for respective collection. The decarburized coal ash is the cement water reducing agent prepared by the device. The loss on ignition (LOI) of the water reducing agent is less than 5 percent and is higher than the requirement on first-grade products of China.
Description
Technical field
The present invention relates to a kind of device for preparing cement water reducing agent with physical method; Especially a kind ofly utilize the metallic conduit friction to make fly ash grain charged earlier; In electrostatic field, it is separated the device that to utilize swirler-to collect highly purified decarburization ash then be cement water reducing agent then.
Background technology
Cement concrete is the maximum material of construction of consumption in the world, but cement concrete exists from great, and intensity is low, the weakness that fragility is big.Along with the high speed development of construction industry, its performance has been proposed to upgrade higher requirement.In cement, adding admixture is to improve concrete strength, improves effective, easy, the economic method of its various performances.
Admixture commonly used and that consumption is maximum is a cement water reducing agent; At present use maximum water reducers like modified lignin resin class water reducer; The naphthalenesulfonate formaldehyde condensation compound high efficiency water reducing agent, polychlorostyrene amine sulfonate and formaldehyde condenses high efficiency water reducing agent, the decarburization ash concrete water reducer of low loss on ignition etc.Described low loss on ignition decarburization ash concrete water reducer; Be that flyash that flyash is carried out obtaining after the sorting is again behind decarbonization process and get; Be a kind ofly can effectively improve the cement concrete quality, the admixture that reduces cost is usually used in producing building materials, chemical fertilizer, extraction metal etc.
China is that a few is one of country of main energy sources with coal in the world, and coal accounted for 72.9% in China's energy expenditure constitutes in 1998.Coal accounts for about 60% in China's primary energy source structure of consumer demand in 2010, this shows that China is that main Energy production can not change in long-time with the consumption general layout with coal.The environmental problem that the fire coal that consumption is huge produces becomes increasingly conspicuous, China discharging SO in 1998
2Be 2,090 ten thousand tons, 1,452 ten thousand tons of flue dust; Discharging SO in 1999
2Be 1,857 ten thousand tons, 1,159 ten thousand tons of flue dust, wherein relevant more than 75% with coal burning pollution.Along with the increase of large-size thermal power plant, China's flyash quantity discharged is increased sharply to 1.6 hundred million tons of 2000 by 2675.2 ten thousand tons of 1979, and described flyash is a kind of pozzolanic materials that gives off behind the coal dust firing, has another name called flying dust, cigarette ash.The average year quantity discharged of China's flyash is about 1.8 hundred million tons at present.Present national fuel-burning power plant is always stored the flyash amount and is surpassed 2,200,000,000 tons, about 440,000 mu of ash disposal area land occupation and good farmland, but China's utilization of coal ash rate is only paced up and down about 30% always.This shows that a large amount of depleted flyash are not used, not only polluted water and air destroy environment, have have also occupied many arable lands simultaneously, influence weather, destroy ecological.Therefore being familiar with flyash as a kind of resource and making full use of, is to be related to strategy of sustainable development urgent problem.
Flyash is carried out can obtaining three kinds of products after the triboelectric separator sorting: decarburization ash, middle ash and coal grain.The decarburization ash of low loss on ignition has a lot of purposes, can make the cement blended stock and produce various pulverized fuel ash cements.This water reducer is for improving cement quality, and it all is very beneficial reducing cement cost and mass consumption flyash.Simultaneously, the decarburization ash of this low loss on ignition also can be used for having the flyash water reducer of very high practical value and economic worth, i.e. cement water reducing agent; And the coal dust that sorting flyash obtains can be done the inferior fuel sale or boiler of feeding flashes back, because its highly porous reticulated structure can also be processed into activated carbon, further opens up it and utilizes approach
China's coal ash sorting technical study originates in the end of the seventies, forms dry method and wet method two big series.The wet split technology is floated pearl in sorting, selects iron and is selected aspects such as carbon to obtain certain progress; But; In view of wet processing flow process complicacy; Must rely on drying plant, and produce waste water and contaminate environment, thereby dry process flyash technology has more meliority than wet method sorting technology under comparing; The dry separation technology then demonstrates its meliority aspect the qualities such as fineness of pulverized-coal ash, loss on ignition improving.Can reduce its carbon content effectively and adopt electrical concentration to handle flyash, and produce decarburization ash with industrial application value.Loss on ignition (LOI) is one of most important parameter in the national standard of flyash grade classification (GB1596-91): I level flyash: LOI≤5%; II level flyash: LOI≤8%; III level flyash: LOI≤15%.The flyash grade is high more, and it is low more to take off coal ash loss on ignition LOI, and the output of taking off coal ash is just high more.
The charged sorting unit of disclosed electrostatic particle among the CN2745653Y, this sorting unit install one cylindraceous charged in roller, it and hub support and connection are enclosed two semicircular exterior cover pipelines in charged roller outsourcing; Form charged chamber between exterior cover pipeline and the charged roller, in the exterior cover pipeline bottom, order is connected pedestal with exterior cover pipeline lower plate and insulation and connects, in the middle of two exterior cover pipeline bottoms; Be formed with discharge port, above exterior cover pipeline, be connected with the exterior cover pipeline upper plate; Be the material uniform device between the exterior cover pipeline upper plate, the coflow pipe is equipped with at material uniform device open upper end place; In the middle of the coflow pipe, charged grid is installed, charged grid is connected with Charging system respectively.During work, material gets into from the material uniform device, squeezes into air-flow from the coflow pipe, charged material order through charged chamber, discharge port gets into separator and carries out the material sorting.Though this device effect is high, cost is low, is not suitable for being similar to the sorting of this powder of flyash, and assorting room do not have complete closed, and dust pollution is big.
Disclosed frictional static sorting unit among the CN2304472Y; It comprises has the positive or negative high voltage electrode and rolls over band around its discharging by the transmission shaft drive in the separation chamber; Form electrostatic field between two hardboards; The separation chamber lower end connects hopper, and the other end has nozzle, and each links to each other the strigil two ends with load hopper and nozzle.Outside air feed system provides the high speed current-carrying gas for this device, and material is under high velocity air carries and strigil collides, friction, makes coal and mineral substance be with opposite polarity electric charge respectively, realizes separating through electrostatic field.It is rational in infrastructure simple, and is effectively succinct, and not thorough but ore particle separates, yield rate is low.
