Description
Technical field
The present invention relates to field of solar energy more particularly to solar panel to fabricate, and in particular to a kind of solar energy
Solar panel processing-waste circulation recycle system.
Background technology
Currently, world energy sources structure develops towards determining direction, although at present mainly with oil, coal, natural
Based on the non-renewable resources such as gas, but with socio-economic development, new energy technology develops, the transformation of the theory of people,
The utilization of the novel renewable resource of pay attention to day by day, wherein solar energy, and can be as due to the advantage with cleanliness without any pollution
Can almost limitless exploitation the energy, have maximum potentiality to be exploited.
At this stage, the main Land use systems of solar energy have converts solar energy into thermal energy by way of thermal-arrest, Huo Zheli
It is converted solar energy into electrical energy with photovoltaic effect, it is clear that be converted into the mode more with prospects of electric energy, solar cell
(photovoltaic cell) is the most crucial device of solar energy.
In recent years with the development and change in photovoltaic solar market, solar cell is constantly sent out to high-efficiency and low-cost
Exhibition.Polysilicon is widely used as suitable semi-conducting material in photovoltaic solar power industry.As needed, polycrystalline
Silico briquette needs the silicon chip that specific thickness is cut by cutting machine.Since polysilicon hardness is high, it is directed at present large-sized
The cutting of polysilicon, it is contemplated that the pressure that the expansion of industry size and cost increase in terms of silicon chip is constantly sought in the industry efficiently
The silicon chip cutting mode of rate low cost.
There are mainly two types of the cutting modes of existing world photovoltaic industry crystal silicon chip.
One is mortar cuttings, i.e., are looped around drive using more stainless steel finer wire (SW) silks for being coated with silicon carbide and slurry oil
Driving wheel and the upper high-speed rotation of nervous wheel, the grinding slurry high speed based on silicon carbide micro-powder are brought cutting region into and are applied to abrasive material
Lotus is loaded, abrasive material carries out grinding cutting to silicon material.
Another kind is diamond wire (DW) slice, i.e., is embedded in diamond particles using plating or the fixed method of resin
On stainless steel wire, this stainless steel wire runs at high speed carries out grinding cutting with certain pressure to silicon material.From cell making process
Angle changing rate, mortar cutting damage acutely silicon chip surface rubbing crack, silicon chip surface can be made to occur more small and irregular recessed
Hole, is easy to cause follow-up cleaning and texturing complex process and control is unstable, and pyramid matte variation range is big, monolithic pyramid suede
The face uniformity is poor, and nucleation rate is low.
Silicon chip surface also has in addition to there is lighter mantle friction fracture damage and is cut by ductile grinding after diamond wire saw
The smooth cutting line to be formed is cut, the smooth line of plasticity is presented in silicon chip surface and brittle crush is broken the mixing pattern of slight pit, this
Kind of silicon chip surface it is not perishable go out pyramid.But compare from slice process, cutting effect high compared to mortar cutting processing cost
The shortcomings of rate is low, and the exhaust emission of waste mortar is big after cutting, diamond wire saw do not use expensive and reluctant mortar,
Easy to operate, cutting speed can be 2 to 3 times fast, and the throughput rate of promotion is more than 1.5 times, while silicon chip surface damage is lighter, single
Piece consumptive material is cut well below mortar.Therefore Buddha's warrior attendant line cutting technology because its efficiently, environmental protection, good characteristic, gradually at
For the substitute technology of mortar wire cutting.
However, carrying out silicon chip cutting using Buddha's warrior attendant line technology, special cutting liquid is used, what Buddha's warrior attendant wire cutting used cuts
It is Water Soluble Cooling Liquid to cut liquid, for example, the cutting liquid generally used includes mainly nonionic surfactant, polyethylene glycol, alcohol
Class bleeding agent, antirust agent are water-based mixture.For water-based mixture, there is preferable hydrophily to play dispersion silica flour, cooling drop
The effect of temperature ensures to carry out deslagging and cooling during cutting.It can be with water rapidly and uniformly mutual phased soln, emulsibility
It is good, and with certain cleaning, lubrication, antirust function, can effectively prevent silicon chip generation brittleness in cutting process and burst apart or produce
Raw cut, can clean the silicon chip surface after cutting, reduce board and get rusty, express delivery reduces the temperature of cutting region, after cutting
Silica flour energy Effective Suspension, does not generate precipitation；And the coolant liquid is not allowed volatile, such machine for cleaning and cutting platform is with regard to relatively easy.
In addition to this, it is also necessary to carry out the process operations such as degumming, cleaning, cooling, water consumption is very big, therefore needs to prepare in advance
Good water source simultaneously needs to keep process water water supply sufficient for a long time, only in this way just can guarantee the quality of finally obtained product.But
It is that under present water resource present situation more in short supply, a large amount of water resource is not only resulted in using this existing processing method
Waste and in many cases because of processing when workshop in can not ensure the supply of good water resource for a long time, thus processing can be made
It can not safely and effectively ensure water supply during processing, to which the poor product quality processed, processing efficiency can be caused
It is low.The water that current each step has used usual water quality after having used can become very poor, therefore existing equipment is carrying out
Just directly sewage is discharged by drainage pipeline after the processing of complete step process, not only result in the waste of water resource in this way and
And arbitrarily sewage effluent can also cause a large amount of water pollution.
Therefore at present although industry solar energy is clean energy resource, but solar element can pollute in the production process, especially
It is that can consume great lot of water resources, and generate discharge of wastewater.There is the case where " environmental protection industry is not environmentally ", the pollution of industry front end is
Unavoidable problem is needed, is intended to that cutting liquid and other process waters can be recycled in industry, reduces to water source
It relies on, reduces the consumption of water resource, and reduce externally discharge, promote environmental protection index.

It is following to consider：
On the one hand, the main function of cutting liquid is cooled down when diamond wire carries out silicon chip cutting, due to cutting speed
Quickly, the temperature of cutting liquid will certainly be sharply increased, for circulating and recovering cutting liquid, for cutting liquid carry out cooling treatment just at
For necessity.
On the other hand, one of master operation of cutting liquid circulating and recovering is exactly to carry out press filtration to the silica flour carried in cutting liquid
Separation, so as to recycling.And filter press itself will produce many heats during the work time, lead to the raising of temperature,
Temperature is excessively high to generate filter press many influence.
Temperature to filter press working condition influence it is maximum be exactly by the temperature of filtered fluid, it is direct by the temperature of filtered fluid
Influence filter press filter efficiency, filtering whether can normally run.By taking plate and frame type filter-press as an example, when by the temperature of filtered fluid
Degree has been more than the temperature of filter press design, when being more than the temperature of filter plate, can directly result in the deformation of filter press filter board, or make filter
The acid-fast alkali-proof reduced performance of plate, or to accelerate filter plate putrid and deteriorated.So the cutting liquid temperature into filter press is also required to control
System is in reasonable range.
On the other hand, it needs to carry out degumming process after cutting because of silicon chip, cutting liquid is guaranteed at used in degumming process
70 DEG C or so just can be used normally；In order to ensure the sufficient supply for the degumming liquid that degumming process uses, setting liquid is needed to add
The concerned process steps of heat, such as heating or directly de- with such as water configuration of the solvent after heating can be carried out to the degumming liquid configured
Glue.
Based on above-mentioned consideration, technical solution provided by the present invention is provided and is detached to used cutting liquid by press filtration
