Description
Technical field
The invention belongs to technical field of cement production, and in particular to prepare the device and preparation method of cement additive.
Background technique
Cement concrete is the maximum construction material of dosage in the world, but cement concrete exists from great, intensity is low, crisp
The big weakness of property.With the high speed development of construction industry, its performance is proposed and updates higher requirement.Outer add is added in cement
Agent is to improve concrete strength, improves effective, easy, the economic method of its various performance.
The common and maximum additive of dosage is cement water reducing agent, current most commonly used water-reducing agent such as: modification is wooden
Plain class water-reducing agent, naphthalenesulfonate formaldehyde condensation compound high efficiency water reducing agent, polychlorostyrene amine sulfonate and formaldehyde condensation product high efficiency water reducing agent, low fever
Vector decarburization ash concrete water-reducing agent etc..Wherein, low loss on ignition decarburization ash concrete water-reducing agent is obtained after sorting to flyash
Flyash obtained after decarbonization process again, be it is a kind of can effectively improve cement concrete quality, reduce the additive of cost, often
For producing building materials, chemical fertilizer, extraction metal etc..
China is that a few is using coal as one of country of main energy sources in the world, and 1998 in China's energy-consuming structure
Cheng Zhong, coal account for 72.9%.Into China's non-renewable energy structure of consumer demand in 2010, coal accounted for 60% or so, it can be seen that, China
Production of energy and consumptio based on coal will not change in a long time.The huge coal-fired environment generated of consumption figure is asked
Topic becomes increasingly conspicuous, and SO is discharged in China within 19982It is 20,900,000 tons, 14,520,000 tons of flue dust；Discharge SO in 19992It is 18,570,000 tons, cigarette
11,590,000 tons of dirt, wherein 75% or more is related with pollution that caused by coal burning.With the increase of large-size thermal power plant, the discharge of China's flyash
Amount surges by 2675.2 ten thousand tons in 1979 to 1.6 hundred million tons in 2000, and flyash is the one kind given off after coal dust firing
Pozzolanic materials also known as flying dust, cigarette ash.The average annual emissions of China's flyash are about 1.8 hundred million tons at present.Whole nation fire now
Fine coal ash quantity is always stored more than 2,200,000,000 tons in power power plant, about 440,000 mu of ash disposal area land occupation and good farmland, but China's fine coal
The utilization rate of ash is only hovered 30% or so always.It can be seen that largely discarded flyash is not used, not only contaminant water
Matter and air, welding, while many arable lands have also been occupied, weather is influenced, ecology is destroyed.Therefore using flyash as one kind
Resource is recognized and is made full use of, and is be related to strategy of sustainable development urgent problem.
Decarburization ash and coal grain can be obtained after carrying out friction charged sorting to flyash.Low loss on ignition decarburization ash has many use
On the way, cement blended stock can be made to produce various pulverized fuel ash cements.This water-reducing agent for improve cement quality, reduce cement at
Originally and a large amount of consumption flyash are all very good.Meanwhile this low loss on ignition decarburization ash can also be used in very high practical
The flyash water-reducing agent of value and economic value, i.e. cement water reducing agent；And low-grade fuel can be made by sorting the coal dust that flyash obtains
It sells or boiler of feeding flashes back, due to its highly porous reticular structure, activated carbon can also be processed into, further open up it using way
Diameter.
However, existing cement water reducing agent preparation method belongs to chemical preparation mode mostly, material needed for preparation is big
