Description
Technical field:
The present invention relates to the fine powder waste material of silica sand is carried out harmless treatment and comprehensive utilization method, it belongs to the technical field of energy-saving, emission-reducing, environment friendly engineering, specifically a kind of working method and application thereof that utilizes the silica flour waste material to prepare the composite particles frit.
Background technology:
We know that (have another name called: silica sand) be a kind of important industrial mineral raw material, its main chemical compositions is SiO to silica sand
2, and contain Al
2O
3, dirt such as CaO, it is a main bulk raw material of producing glasswork.Study carefully the production technique of its glasswork: it is to adopt to be granular Soda Ash Danse and to mix with silica sand (can allocate raw materials such as feldspar or rhombspar again into according to the needs of production technique) that meets granularity requirements and required auxiliary material and become admixtion; Admixtion is dropped in the glass melter; Making admixtion under about 1500～1700 ℃ temperature, begin to found reacting melt becomes glass metal, again through making glasswork after moulding, the anneal.Obviously, the granularity index of silica sand and distribution of particle sizes composition state are key factors of glasswork quality after directly determining the glass metal quality of being founded and having a strong impact on moulding in admixtion.Cross conference when the particle of silica sand and be difficult to fusing evenly, this will cause chemical reaction not exclusively to produce " calculus " and product defectses such as " stripeds "; When the particle of silica sand is too small, though can improve burn-off rate; The as easy as rolling off a log formation of meticulous silica sand " is flown upward ", " conglomeration " phenomenon also can occur, makes admixtion be difficult for mixing; Particularly in the process of feeding intake, too trickle silica sand powder is very easily brought into by combustion gas flowing and is stopped up cone brick in the regenerator, and this will greatly reduce the working life of kiln; Also can cause the equipment breakdown of being forced to stop production when serious, cause great financial loss.Therefore, the glass production industry all to strictly control the silica sand that uses, soda ash etc. cooperate the granularity index of raw material and the distribution of granularity to form state, and allow to use the fine powder below 150 orders anything but.This also existing just glass production enterprise all generally uses expensive but is particulate state and Soda Ash Danse that density is high and be difficult to use inexpensive but be the basic reason place that Powdered low density Soda Ash Light 99.2min. is made raw materials for production.But; Study carefully its essence; Soda Ash Danse and Soda Ash Light 99.2min. are not distinguishing with a kind of chemical substance on chemical ingredients, and just their physical aspect is different, that is: the profile of Soda Ash Danse is particulate state and Soda Ash Light 99.2min. is Powdered; The density of Soda Ash Danse is high, and the density of Soda Ash Light 99.2min. is low.And the domestic method of existing production Soda Ash Danse is: the water-soluble post crystallization that reaches capacity of Soda Ash Light 99.2min. is generated crystal carbonate crystal grain, again through calcining and keeping intensive crystalline network promptly to become the Soda Ash Danse of high density granular shape.That is to say: Soda Ash Danse is obtained through hydration (increase crystal water) by Soda Ash Light 99.2min..Understand according to existing market: the price of Soda Ash Danse per ton is higher about 200 yuan than Soda Ash Light 99.2min., and this is a reason of glass production enterprise " to cause producing the glass cost as raw material high because of the expensive Soda Ash Danse of use valency " just also.And for the silicon ore deposit manufacturing enterprise that the silica sand raw material is provided for glass industry, it is through repeatedly fragmentation, multilayer are sieved and washed the silica sand raw material that operation just can sub-elect the requirement of granularity accords with production glasswork with silicon ore piece material.Need not to dare not or would not speak up, in silica nugget material being carried out repeatedly fragmentation, screening operation process, can produce a large amount of fine powder waste materials inevitably, the border produces investigation statistics factually: the fine powder waste material of out of use silica sand below 150 orders just accounts for 25～35%.At present; Quantity so huge silica sand fine powder all is that directly discharging is discarded in peripheral place; Pile up like a mountain year in year out; Become a serious threat ecotope, still be difficult to digest " powder mound design " source of pollution public hazards of solution so far, this seat " powder mound design " can fly upward with the wind through sun drying and be spread in the air and rain and can pour field rivers serious environment pollution.Environmental administration orders to forbid to efflux and require to take measure such as landfill or storehouse stacking on the spot again and again, but this needs bigger landfill place or builds very big stores.To be objective, this measure also is difficult to realize real implementing for the moment, and in fact this also can not really solve the pollution problem of the fine powder dead meal of silica sand.Up to now, do not retrieve relevant report as yet in the document at home and abroad about " the fine powder dead meal of the recycling comprehensive utilization following silica sand of 150 orders " yet.How could develop this huge " powder mound design " and it is used as the raw material of producing glass and then the manufacturing cost that reduces glass? This be present China silica sand production industry face jointly be related to the great environmental protection problem that can survive and develop; Also be the great technical difficult problem that China's silicon Mineral industry and glass production industry press for solution simultaneously, this present invention just wants the problem that solves.
