Description
Technical field
It is specifically a kind of to be cut with polycrystalline silicon ingot casting waste material and crystalline silicon the present invention relates to siliceous fertilizer production technical field
The method of slug siliceous fertilizer.
Background technology
With the development of society, the photovoltaic industry using list, polysilicon solar cell as representative has obtained development at full speed.
Wherein, list, the growth of polysilicon, the cutting of ingot casting and silicon chip are to prepare one of important step of crystal silicon solar energy battery.
During this, silica crucible used in polycrystalline silicon ingot casting is disposable product, and consumption is especially big.It is completed in ingot casting
Afterwards, the silica crucible of melting is converted into cristobalite material, and turns into trade waste.Past processing mode is usually simple broken
As building filler to use after broken, have developed into needs pay the freight ability someone to be ready to pull away at present.From now on, with environmental protection
The constantly improve of policy, it will also be handled as Industrial Solid Waste and pay huge disposal costs.For list, polysilicon chip
Cutting, although Buddha's warrior attendant wire cutting technology just progressively substitutes mortar cutting, no longer need from now on processing be difficult to the carborundum that separates and
Silica flour, but slug caused by Buddha's warrior attendant wire cutting at present, mainly or after carrying out separation of solid and liquid are directly sold to individual consumer,
Added value is relatively low.So not only cause the great wasting of resources, at the same also add prepare crystal silicon solar energy battery into
This.Therefore, how effectively whole photovoltaic industry has been turned into urgently using fused silica crucible and crystalline silicon diamond wire cutting waste material slurry
The problem of to be solved.If discarded crucible and cutting waste material slurry can be transformed into high added value by certain processing
Product, it can not only save the expense spent in the past on the useless crucible of processing and solve the environmental problem that industrial residue is brought,
Objective income can be also brought, reduces the cost of crystal silicon solar energy battery.
The granted patent " fused silica crucible renovation process after polycrystalline silicon ingot casting " that Chinese invention patent specification is announced, specially
Profit number for " ZL201410155232.4 " and " it is a kind of using waste quartz crucible preparation cristobalite matter electroceramics ", Patent No.
The method that " ZL2012105532204.0 " describes two kinds of disposal fused silica crucibles respectively.But both approaches are required for
High-temperature calcination is carried out to silica crucible, production cost is high, and its value-added content of product is relatively low, and economic feasibility is poor.In addition,
Granted patent " a kind of side of crystalline silicon diamond wire saw slug recycling that Chinese invention patent specification is announced
Method ", Patent No. " ZL201610086247.9 " describe a kind of method for disposing diamond wire cutting waste material slurry.This method is same
It is to dispose cutting waste material slurry using the method for high melt, the silica flour in slug is smelted into HIGH-PURITY SILICON.But this side
The production cost of method is high, is only suitable for the relatively low region of electricity price, and adds cost of transportation, and generalization is poor.
On the other hand, important element of the silicon as content on the earth second, it is that plant institute is necessary in addition to nitrogen, phosphorus, potassium
The fourth-largest nutrient.For happiness silicon plant especially this kind of to rice, supplement element silicon can in time in its growth course
To form siliceous cell, hence it is evident that strengthen disease resistance, lodging tolerance of crop etc..Moreover, the presence of element silicon can also promote
Absorption of the plant to other nutritional ingredients, strengthen photosynthesis of plant, have the function that further to improve crop yield.At present,
The siliceous fertilizer of in the market is mainly " solubility in citric acid " siliceous fertilizer using blast-furnace cinder as raw material, and its Determination of Soluble Silicon is extremely low, and fertilizer efficiency is very poor.
Therefore, how to improve the validity of siliceous fertilizer is always to restrict the bottleneck of siliceous fertilizer development.
Chinese invention patent specification discloses a granted patent " a kind of liquid silicon fertilizer and its production technology ", the patent No.
It is that other auxiliary materials are made with raw material of industry potassium silicate or sodium metasilicate for " ZL200810238522.X ".In production by adding
The auxiliary materials such as biochemical fulvic acid, chelating agent, trace element, urea are added to be mixed to prepare liquid silicon fertilizer.Its main function composition is " soluble
Silicon " and other auxiliary materials are direct purchase gained, from cost, do not possess competitiveness.
The content of the invention
