Description
Technical field
The present invention relates to a kind of improvement haze powder shipping storage process airborne dust environmental protection covertures.
Background technology
Flyash refers to that coal-burning power plant and gangue, coal slime resources-comprehensive utilization power plant boiler smoke are received by deduster
The tiny flying dust and clinker obtained after collection.The yield of flyash is very big, usually often consumes 2 tons of coals and just will produce 1 ton of flyash.
It is introduced according to national building materials industrial technology Institute of Social Science Information professor Cui Yuansheng, as coal big country, the flyash in China produces
Amount remains high always, and national 6.2 hundred million tons of flyash yield in 2015, potentiality to be exploited is huge." power industry is the production of flyash
Raw rich and influential family.From 2002, China's firepower filled motor group and explosive growth is presented, and flyash yield also sharply increases, from
2001 to 2013, yield increased 3.1 times." flyash stacked of flood tide not only pollutes environment, but also causes resource unrestrained
Take.Gangue is the solid waste of discharge during coal mining process and coal washing, and main component is Al2O3、SiO2, in addition also contain
There is Fe in varying numbers2O3、CaO、MgO、Na2O、K2O、P2O5、SO3With micro rare element (gallium, vanadium, titanium, cobalt).According to incomplete
Statistics, Chinese gangue yield reaches 700,000,000 tons within 2015.
According to parties concerned's data statistics, coal in China industry general status is by the end of the year 2015, national coal mine total scale
It it is 5,700,000,000 tons, 36.8 hundred million tons of national coal production, Railway Coal ships 2,000,000,000 tons.Coal is in storage, transportational process, due to wind-force
Etc. reasons can be lost in, shed airborne dust, long term storage will appear dieseling, cause damages.According to statistics, it is transporting and is storing at present
In the process, coal loss is about 2.6%-2.8%.
It announces in national environmental protection portion：2015, the whole nation shared 246 big or middle cities and has issued solid waste to society
It pollutes environment and prevents information.This big or middle city general industrial solid waste yield to release news is 19.1 hundred million tons, industry
Hazardous waste yield is 2801.8 ten thousand tons, and clinical waste yield is about 68.9 ten thousand tons, and Output of Domestic Waste is about 18564
Ten thousand tons.The extra large cloud of Urban Construction in China research institute professor of engineering Xu is told《Maeil Business Newspaper》Reporter, China city
The refuse production per capita of practical resident population is not compared with developed countries high, but future is with economic development, the level of consumption
Raising, the trend that Municipal Garbage Yield comparatively fast increases will continue.
Northern China city haze phenomenon is increasingly severe in recent years, and haze is at a pain spot in the minds of the common people, seriously
Ground affects national economy.Dust raising phenomenon during powder class material (flyash, coal, rubbish etc.) shipping storage, after shedding
One of the reason of pollution environment, the health for seriously affecting staff is also generation haze phenomenon.Tradition prevents powder from transporting
The method of the dust raising phenomenon of defeated storage process, use is two methods of watering and tarpaulin.Watering method：Moisture evaporation is fast, no viscous
Knot property, persistence are bad；Tarpaulin method：It is of high cost, use inconvenience.
Invention content
Based on the above shortcoming, the present invention relates to a kind of improvement haze powder shipping storage process airborne dust environmental protection coverings
Agent sprays one layer of coverture on powder material surface, after so that its surface is formed cured layer, prevents powder airborne dust from avoiding to ring
The pollution in border, while cured layer has completely cut off air circulation, additionally it is possible to prevent the dieseling of coal dust.
Above-mentioned purpose is realized by following technical scheme：A kind of improvement haze powder shipping storage process airborne dust environmental protection
Coverture, formula includes following weight ratio：30-50 parts of gangue, 5-10 parts of kaolin, 5-10 parts of magnesia, gypsum 5-10
Part, 15-25 parts of maize straw, 15-20 parts of rice husk, 5-10 parts of binder.
The present invention also has following technical characteristic:
1, a kind of improvement haze powder shipping storage process airborne dust environmental protection coverture, formula includes following weight ratio：Powder
35-40 parts of coal ash, 5-10 parts of kaolin, 5-10 parts of magnesia, 5-10 parts of gypsum, 15-25 parts of maize straw, 15-25 parts of rice husk,
5-10 parts of cement.
2, above-described bastard coal mountain flour is 30-200 mesh, and gypsum is 60 mesh hereinafter, maize straw is 2-5 mesh, and rice husk is
2-5 mesh.
3, above-described fine coal ashes is 100 mesh hereinafter, gypsum is 60 mesh hereinafter, maize straw is 2-5 mesh, and rice husk is
2-5 mesh.
Beneficial effects of the present invention are as follows：Commerical test the domestic coal mine in Heilongjiang Province, thermal power plant, refuse depot into
Row.After coal, flyash, rubbish heap spray the coverture, after 4 to 12 hours, that is, complete hard formation (6-12 millimeters thicks) is condensed into.
The hard formation is washed away through multiple summer rainwater with after Heavy snow thawing, is not ruptured.During commerical test, to hard formation
Compressive resistance, anti-shearing force are tested.Hard formation compression strength is 3500-4500pa, shearing force 900-1100pa.Resistive,
When wind-force reaches eight grades, hard formation does not rupture.The hard formation intensity that the coverture of the present invention generates is high, and use is easy to operate, reaction
Temperature room temperature, formula raw material sources are extensive, at low cost.
Specific implementation mode
The gangue that the present invention uses is the solid waste discharged during coal mining process and coal washing, is one kind in coal-forming mistake
The black and gray rock relatively low, harder than coal with a kind of phosphorus content of coal seam association in journey.Flyash is from the flue gas after coal combustion
The fine ash that middle catching is got off, flyash are the primary solids wastes of coal-burning power plant's discharge.The main oxygen of power plants flyash
Compound group becomes：SiO2、Al2O3、FeO、Fe2O3、CaO、TiO2Deng.With the development of power industry, the flyash of coal-burning power plant
Discharge capacity increases year by year, becomes larger one of the industrial residue of the current discharge capacity in China.A large amount of flyash is untreated, will produce
Raw airborne dust, pollutes air；River can be caused to silt up if being discharged into water system, and toxic chemical substance therein can also be to human body and biology
It causes damages.But flyash can resource regeneration, such as powder shipping storage environmental protection coverture of the present invention development blending
Material etc..First, selecting chemical binder, two class of hydraulic cementing materials cement to make curing agent, carrying out reasonable grade to material particles degree
Match；Second is that network polymerisation and hy-dration reaction occur between Applied Physics principles of chemistry material.
