Abstract
The utility model discloses a device for filtering and recycling hypo acid for soaking a silicon material. The device comprises a pickling tank, wherein a filtering baffle net is arranged at the inlet end of the pickling tank, the outlet of the pickling tank is connected with an acid storage pond, a filtering basket is arranged on the inlet end of the acid storage pond, and the outlet of the acid storage pond is connected with a pump. According to the utility model, problems of filtration and recovery of silicon material pickling solution can be solved. The device has the characteristics of simple structure and capability of recycling recovery liquid.
Description
Technical field
The utility model relates to a kind of filtering recovering device, and particularly a kind of silicon material soaks the hypo acid filtering recovering device.
Background technology
Solar energy polycrystalline silicon ingot casting or pulling monocrystal silicon rod all need use polysilicon to be raw material.Because the polycrystalline silicon raw material surface has some impurity and dust, so before polycrystalline silicon raw material is used, all need to clean with pickle.The tiny silicon material of normal discovery falls into descaling bath or soak groove in silicon material acid cleaning process; Having partly, the silicon material can be discharged from along with one of hypo acid; There is part silicon material in the acid discharge process, to block valve or acid tube easily in the dimension acid, brought great trouble for production and maintenance, and also have the minor amount of silicon materials flow to lose; Cause certain material loss rate, reacted hypo acid also has the material of considerable part not react and can also utilize again in fact.Before utilizing again, need to use filter that the pickle that contains the silicon material is filtered, could realize that the silicon material no longer runs off, and the utilization again that hypo acid also can be clean.At present the photovoltaic industry does not also have special retracting device in producing, and directly drains hypo acid after just using up once.
The utility model content
Its purpose of the utility model just is to provide a kind of silicon material to soak the hypo acid filtering recovering device, has solved the problem that silicon material pickle filters, reclaims.Have characteristics simple in structure, as to reclaim the liquid reusable edible.
The technical scheme that realizes above-mentioned purpose and take comprises pickling tube, and said pickling tube entrance point is provided with the baffle net, and the pickling tube outlet connects the sour pond of storage, stores up sour pond entrance point and is provided with filter basket, and said storage acid pond outlet connects pump.
Compared with prior art the utlity model has following advantage,
Owing to adopted the structural design of baffle net and filter basket, thereby solved the problem that silicon material pickle filters, reclaims.Have characteristics simple in structure, as to reclaim the liquid reusable edible.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to detail.
Fig. 1 is this apparatus structure principle schematic.
Fig. 2 be among Fig. 1 A to view.
The specific embodiment
This device comprises pickling tube 1, and is as shown in Figure 1, and said pickling tube 1 entrance point is provided with baffle net 2, and pickling tube 1 outlet connects the sour pond 6 of storage, stores up sour pond 6 entrance points and is provided with filter basket 3, and said storage sour pond 6 outlets connect pump 7.
6 upper ends, the sour pond of said storage are provided with exhaust outlet 5 and lid 4.
Said baffle net 2 is an acid resisting material PP plate, and the aperture is 3mm; Said filter basket 3 acid resisting material PP plates, the aperture is 1.5mm.
The material of its preparation have the PPR of PP plate one and half, ∮ 63 pipe (6m), a ∮ 63PPR elbow, threeway, each three; Three on the falling sphere valve alive of ∮ 63, one on the pipe of two of the ball valves of PPR ∮ 32 and PPR ∮ 32.With macromolecule PP plate punching, the baffle net of making the aperture and be 3mm is put into pickling tube and is carried out filtration first time; Use the PP plate to make the aperture again and be the 1.5mm filter basket, the end of discharging at pickling tube carries out the filtration second time, can realize that acid separates fully, reclaims with the silicon material.
Adopt the still recyclable utilization of hypo acid after twice filtration, also alleviated pressure simultaneously to sewage disposal, finally practiced thrift product cost of material, also brought benefit to environmental protection.Cost through using soak after the two road acid recovery systems reduces about half.
The effect of its twice filtration is: filter for the first time and can prevent that the silicon material of some is discharged greatly when discharging; Filter for the second time, can prevent that the little silicon material of particle diameter is discharged from.Filter the hypo acid recycling just capable of circulation of silicon material, improved the utilization rate of pickle.
