Abstract
During the storage of the ash for discharge, transportation and production, the fly ash is a serious pollution source because of small volume weight, small particle size and good fluidity and dust is raised when meeting wind. The invention provides a new covering material and a method for preventing fly ash from flying. The covering material is made of inorganic material, and is mechanically sprayed on the surface of fly ash to form physical and chemical covering, and has the properties of water resistance, heat aging resistance, weak alkali resistance, frost resistance and the like, and the covering thickness is thin, and the effective acting period is more than 9 months.
Description
Power system both at home and abroad is mainly based on the coal thermal power generation, and China only discharge coal ash in 1989 reaches 6215.4 ten thousand tons, and utilization rate is 25.7%, is taking a large amount of soils.Because of flyash unit weight is little, grain diameter is little, is garden ball-type shape, good fluidity, and in flyash discharging, transportation and producing with grey storage process, meeting wind is airborne dust, contaminated area is big, is serious pollution sources.Traditional covering method is to cover with soil and water.Cover with soil, the manpower construction, cladding thickness is big, reduces storage capacity, and labour intensity is big, and efficiency of construction is low, expense is high; Water covers, and damages grey dam or because of the good penetrability of flyash, the very fast infiltration flyash of water bottom, and under wind-force, temperature effect, the flyash dry tack free, meeting wind is airborne dust.The present invention provides new cladding material and method for preventing flyash dust pollution environment.Covering material for coal powder ashes mainly is made up of inorganic material, as silicate of soda colloidal sol, potassium silicate colloidal sol, CaSO
4, CaO, portland cement, magnesia oxychloride cement, kaolin, swell soil, starch etc. and asbestos fiber, glass fiber, string, polymer fiber etc. and Na
2SIF
6, NaNO
2, Na
2SO
4CaCL
2Deng curing compound early strength admixture, as portland cement: fiber: Admixture=89: 6: 2. and according to circumstances add suitable water and be stirred to pulpous state, adopt machinery to spray, form cured layer to the flyash surface.The theoretical foundation that the present invention develops proportioning is creatively to have proposed " cladding thickness relatively ", " rupture load relatively " and " covering economy " three basic conceptions, and proposes should adopt the cladding material with certain intensity the mechanical property of the material of relative rupture load evaluation when necessarily covering the square meter expense.
Because this covering material for coal powder ashes system is made up of inorganic material, and adopt the machinery spray to construct, have water-fast, heat-proof aging, anti-weak base, freeze proof, to performances such as environment non-secondary pollutions, the cladding thickness a surname, do not reduce storage capacity, the efficiency of construction height, the covering expense is little, through the commerical test of two phases, the useful effect phase this more than 9 months, do not influence the further utilization again of comprehensive utilization and ash of flyash, remarkable social benefit is arranged, environmental benefit and economic benefit, and be tested and appraised on December 13rd, 1993, " this achievement provides new cladding material and method for preventing the flyash airborne dust to one of its expert's conclusion; have important practical significance; have broad application prospects, and belongs to domestic initiation, fills the domestic gaps.”
Claims (2)
- Covering material for coal powder ashes and job practices principal character thereof are creatively to have proposed " covering economy ", " cladding thickness relatively " and " relative rupture load " three basic conceptions, proposition should adopt relative rupture load to evaluate its mechanical property to the cladding material with certain intensity, develop covering material for coal powder ashes that is composited and the job practices thereof be made up of inorganic material, its claim is as follows:1, cladding material: silicate of soda colloidal sol, potassium silicate colloidal sol, CaSO 4, one or more are compound or mix asbestos fiber, glass fiber, string, polymer fiber etc. or mix NaSIF for CaO, portland cement, magnesia oxychloride cement, kaolin, swell soil, starch etc. 6, NaNO 2, NaSO 4, CaCL 2, curing compound such as NaCL or add the cladding material of suitable quantity of water through formulated pulpous state.
- 2, job practices: to the cladding material slurry for preparing, adopt construction appliance, get final product mechanized construction as foul water pump, mortar pump, centrifugal pump, spraying spray etc. with certain pressure.
