Abstract
The invention provides a mortar recycling device for recycling waste mortar. The mortar recycling device comprises a primary centrifugal machine, a secondary centrifugal machine, a filter unit and a distillation unit. The primary centrifugal machine is used for primarily separating the waste mortar to obtain recyclable carborundum and to-be-separated liquid. The secondary centrifugal machine is used for secondarily separating the to-be-separated liquid to obtain polyethylene glycol liquid. The filter unit is used for filtering out impurities in the polyethylene glycol liquid to obtain purified polyethylene glycol liquid. The distillation unit is used for distilling and cooling the purified polyethylene glycol liquid to obtain recyclable polyethylene glycol.
Description
Technical field
Present technique relates to mortar online recycling device, be mainly used in silicon ingot cutting in photovoltaic industry or semicon industry, or the recycling of silicon chip cutting mortar used, it can improve the utilization rate of cutting mortar greatly, thereby reduced the cutting cost of silicon chip, reduced to greatest extent and take the mortar pollution on the environment.
Background technology
In the solar energy industry, the silicon chip cutting technique is to drive the cutting mortar with steel wire to come the grinding silicon ingot.Used cutting mortar becomes a kind of industrial production " refuse ".These refuses that produce in the cutting of photovoltaic industry silicon chip are mixed by liquid component (polyethylene glycol) and solid constituent (silicon carbide micro-powder).It is a kind of material of pulp, generally is called " useless cutting liquid ", " waste mortar " by people.These industrial wastes were once discarded by people in the past, and how manufacturer also for disposing these " waste materials ", and were not found and puzzle one's brains by the department such as environmental protection and the masses.But, in these so-called " refuses ", contain very high the utilized composition of a lot of value, as diamond dust, polyethylene glycol etc.
Cut the continuous decrease of reshuffling of industry and profit along with solar silicon wafers, silicon chip cuts enterprise and coincidentally begins the optimal control production process, reduces production costs.Be exactly the most directly to the cutting liquid in three large auxiliary materials and the recycling of silicon carbide micro-powder.By the recycling to waste mortar, can make the cost at least 50% of cutting liquid and silicon carbide micro-powder.Improve raw-material utilization rate, reduce spillage of material; Reducing processing charges etc. has become photovoltaic enterprise and has reduced production costs, the most urgent requirement of increasing economic efficiency.
Summary of the invention
The purpose of present technique is to provide a kind of mortar recovery device that waste mortar is recycled.
This mortar recovery device, but it comprises, waste mortar is carried out the first-stage centrifugal seperator that one-level is isolated reuse carborundum and liquid to be separated, treat separating liquid to carry out the second-order separation and obtain the secondary centrifugal separator of polyethylene glycol liquid, the polyethylene glycol impurities in liquid is filtered and obtains the filter of purifying polyglycol solution, but the purifying polyglycol solution is distilled cooling and obtains the distilling apparatus of reuse polyethylene glycol.
Above-mentioned mortar recovery device, but but it also comprises the mixing arrangement that reuse polyethylene glycol reuse carborundum, new carborundum, new polyethylene glycol are mixed.
Above-mentioned mortar recovery device, described filter comprise plate type pressure filter, the film filter of order series connection, the ion-exchanger of filtering type.
Above-mentioned mortar recovery device, it also comprises heats and reduces the heat exchanger of its concentration the polyethylene glycol liquid before filtering.
Centrifugal separator, filter (as the ion-exchanger of plate type pressure filter, film filter, filtering type), heat exchanger etc. all belong to prior art, no longer describe.
The beneficial effect of present technique: present technique can effectively be separated the carborundum in waste mortar and polyethylene glycol, make them again to be utilized, not only can reduce the photovoltaic industry production cost but also can reduce to greatest extent waste mortar to the pollution of environment.
Description of drawings
Fig. 1 is the schematic diagram of this retracting device.
Fig. 2 is the outflow schematic diagram that mortar reclaims.
The specific embodiment
By reference to the accompanying drawings present technique is further described below by embodiment.
Shown in Figure 1, this mortar recovery device comprises but waste mortar is carried out the first-stage centrifugal seperator that one-level is isolated reuse carborundum and liquid to be separated, treat separating liquid to carry out the second-order separation and obtain the secondary centrifugal separator of polyethylene glycol liquid, polyethylene glycol liquid is heated and reduces the heat exchanger of its concentration, the polyethylene glycol impurities in liquid after heat exchange is filtered and obtains the ion-exchanger of plate type pressure filter, film filter and the filtering type of purifying polyglycol solution; But the purifying polyglycol solution is distilled cooling and obtains the distilling apparatus of reuse polyethylene glycol.First-stage centrifugal seperator 1, secondary centrifugal separator 2, heat exchanger 3, plate type pressure filter 4, film filter 5, the ion-exchanger 6 of filtering type, distilling apparatus 7 grades are connected successively.
But but reuse polyethylene glycol reuse carborundum, new carborundum, the new mixed storage tank (mixing arrangement) 8 that adds of polyethylene glycol.
referring to Fig. 2, this online recycling device directly carries out two-stage centrifugal to waste mortar to be separated: first-stage centrifugal is isolated available carborundum and liquid to be separated, liquid to be separated goes out polyethylene glycol liquid via the secondary centrifugation, isolated liquid makes fluid temperature raise the reduction strength of fluid by by board-like press filtration, it being carried out the filtration of impurity through heat exchange again, and then filter through essence, ultrafiltration, the membrane filtration separating technologies such as carbon filter process to coarse filtration liquid that (membrane filtration is the relevant screening process of a kind of and membrane aperture size, take the pressure differential of film both sides as driving force, take film as filter medium, under certain pressure, when stoste flows through the film surface, the many tiny micropore that gathers in the film surface only allows water and small-molecule substance by becoming through liquid, in stoste, volume is trapped within the liquid feeding side of film greater than the material in film surface micropore footpath, become concentrate, thereby realize the separation of stoste and concentrated purpose), thereby the granule impurity in the polyglycol solution of coarse filtration is rejected, and because membrane filter media is the even non-individual body of being made by macromolecular material, it is pure physical methods of filtration, the variation (namely not affecting the molecular structure of material) of matter does not occur in material in separation process, pass through again at last ion-exchange and (usually adopt filter type, filter bed is made of exchanger, the bottom is the piping with filter) the purifying polyglycol solution.Replenish by a certain percentage fresh sand and new liquid after the polyglycol solution of purified mistake is cooling by distillation again, and mixes with carborundum that one-level is separated, be used in multi-line cutting machine through direct circulation after stirring.So not only can reduce the photovoltaic industry production cost but also can reduce to greatest extent waste mortar to the pollution of environment.
This is a kind of brand-new waste mortar online recycling treatment process, be equipped with advanced control system and on-line detecting system, make the operation fully automatically of this equipment, each operative employee can nurse two to three equipment simultaneously, greatly reduce workman's labour intensity, improved production efficiency.The waste mortar rate of recovery of this equipment reaches 85% left and right, through the mortar that reclaims, can guarantee that the yield rate of cutting into slices is the same with new mortar.
