Description
Technical field
The present invention relates to cutting waste liquor treatment facility field, especially a kind of equipment for separating liquid from solid for cutting waste liquor.
Background technology
Silicon chip is the main production material in semiconductor and photovoltaic field, Multi-wire wafer cutting technique is current more advanced silicon chip process technology in the world, it is different from traditional knife saw sheet, the cutting modes such as grinding wheel, also be different from advanced laser cutting and inner circle cutting, its principle is to drive the cutting liquid being attached on steel wire to rub to silicon rod by the steel wire of a high-speed motion, thereby reach cutting effect, in whole process, steel wire is by the guiding of line roller, on online roller, form a bracing cable net, and workpiece to be processed is realized the feeding of workpiece by the decline of workbench.Multi-wire wafer cutting technique has compared with other technologies that efficiency is high, and production capacity is high, precision advantages of higher, and therefore, multi-wire saw technology is silicon chip cutting technique the most widely at present.
In multi-wire saw technology; the cutting liquid using is normally formulated according to a certain percentage by the silicon-carbide particle of polyethylene glycol and 1200 orders left and right; cutting liquid inevitable meeting in the process of cutting silicon rod mixes with the silica flour under cutting; form a large amount of cutting waste liquors; and in cutting liquid can there is breakage because of dissection in part silicon-carbide particle; the order number of partially carbonized silicon is increased, and therefore, cutting waste liquor cannot directly reuse.In cutting waste liquor, contain a lot of resources, such as carborundum, silica flour etc., if directly emitted, not only cause waste resource, also pollute the environment simultaneously, therefore, be a difficult problem for photovoltaic industry for the processing of cutting waste liquor always.
At present, processing method for cutting waste liquor adopts following mode conventionally: first, cutting waste liquor is carried out to Separation of Solid and Liquid, separate with silicon-carbide particle, silicon powder particle by the polyethylene glycol liquid in cutting waste liquor, obtain polyethylene glycol liquid and the carborundum solid that is mixed with silica flour, isolated polyethylene glycol liquid can again be mixed with cutting liquid recycling as raw material after further processing; Then, the carborundum that is mixed with silica flour of separating is carried out to classification processing, remove order number and be greater than 1300 object superfine silicon carbides, the carborundum that remaining order number is less can be made into new cutting liquid to be continued to use, because the density of carborundum and silica flour is more or less the same, therefore, in remaining carborundum or the superfine silicon carbide of separating, all contain silica flour no matter be; Finally, the superfine silicon carbide that is mixed with the silica flour larger number of separating is emitted after chemical treatment.Existing cutting waste liquor processing mode only can be recycled polyethylene glycol and a part of carborundum, generally cannot effectively recycle for the superfine silicon carbide in cutting waste liquor and silica flour.
At present, for polyethylene glycol liquid and carborundum in cutting waste liquor, silicon grain separates the main mode that adopts centrifugal separation, , first in cutting waste liquor, add a certain amount of water, polyethylene glycol is dissolved in water completely, then aforesaid liquid is passed into horizontal spiral centrifuge, by multistage centrifugal processing, realize polyethylene glycol liquid and carborundum, silicon grain separates, then polyethylene glycol is distilled process and can obtain polyethylene glycol, this mode needs special centrifugation apparatus and the distillation equipment bought, the cost dropping into is larger, and, these two kinds of equipment need to consume a large amount of electric energy in the time of work, further increase production cost.
Summary of the invention
