Technical field
The utility model relates to ultrafiltration apparatus field, specially refers to the concentrated ultra-filtration equipment of using of a kind of aluminium colloidal sol depickling.
Background technology
Aluminium colloidal sol is as a kind of inorganic polymer multivalence polymkeric substance, and its good performance more and more comes into one's own.It is applied to the binding agent of catalytic cracking catalyst, can strengthen its abrasion resistance, can improve again activity, and adopts sol-gel method to prepare activated alumina material, not only aperture structure homogeneous, and can regulate and control with comparalive ease preparation parameter.Aluminium colloidal sol can also be directly as petrochemical catalyst, support of the catalyst simultaneously; The high temperature resistant moulding bonding agent of aluminum products and ceramic; The binding agent of precision casting section bar; The additive of pottery, frit for porcelain enamel; The membrane-forming agent of yarn fabric and fabric processing treatment, emulsifying agent and the tranquilizer etc. of static inhibitor and pigment, coating, it is widely used, and is a kind of rare good inorganic materials.
That on world market, sells is generally the more than 4 aluminium colloidal sol of pH value, and is domesticly mostly the acidic aluminum sol that pH value is 2-3.For a long time, domesticly developing always, developing the more than 4 aluminium colloidal sol product of pH value, existing producer is in the trial production stage, but the product of producing is commonly creamy paste pasty state, and its particle size analysis is also in micrometer level.
In order to shorten and the gap of world level, domestic expert through further investigation developed multiple pH value be 4-7, particle size analysis 60 nanometers left and right, transparency aluminium colloidal sol products preferably, and product has more typical colloid feature, its outward appearance is translucent to transparent thickness colloid.
Research is found, aluminium colloidal sol produce in the control of the removing of acid and small-molecule substance, colloidal particle size, it is the key factor that obtains high-quality aluminum colloidal sol product, tradition reduction vaporization concentration method can be removed most of moisture and volatile acid, but soluble small molecular is difficult to remove, and adopts evaporating and concentrating process energy consumption and pollute larger.Ultra-filtration membrane is a kind of perviousness separatory membrane of selecting, can effective elimination water and soluble small molecular including acid, guarantee that the macromole of certain molecular weight can not see through, in adopting, pressure-pipe type ultra-fine filter puts forward just for the depickling of aluminium colloidal sol is concentrated under this background.
Summary of the invention
The purpose of this utility model is to provide a kind of hyperfiltration membrane assembly that utilizes to carry out the concentrated ultra-filtration equipment of using of the concentrated aluminium colloidal sol depickling of depickling to aluminium colloidal sol.
For achieving the above object, the technical solution of the utility model is:
The depickling of a kind of aluminium colloidal sol is concentrated with ultra-filtration equipment, comprise cleaning case, ultrafiltrate pump, web member, hyperfiltration membrane assembly, clear liquid collection tube, turbid liquid collection tube, electrical control cubicles and work tank, the hyperfiltration membrane assembly two ends of this device are connected with web member and are contained on membrane stack support, work tank is connected with ultrafiltrate pump with stoste transfer lime, the other end of ultrafiltrate pump is connected with the inlet end of hyperfiltration membrane assembly, hyperfiltration membrane assembly two ends purified liquor outlet is connected with clear liquid collection tube, one end of clear liquid collection tube is connected with clear liquid discharging pipe and clear liquid transfer lime, clear liquid transfer lime is connected with cleaning case top, the dope exit end of hyperfiltration membrane assembly is connected with turbid liquid collection tube and turbid liquid output tube, turbid liquid collection tube is connected with cleaning case top by turbid liquid input tube, turbid liquid output tube is connected with work tank, delivery pipe is equipped with in cleaning case bottom, cleaning case top is connected with pure water transfer lime, electrical control cubicles is connected with each valve and ultrafiltrate pump on pipeline with wire.
Positively effect of the present utility model is: this device is applied to ultra-filtration technique in aluminium colloidal sol depickling concentration technology first, and it is low to have investment cost compared with traditional normal pressure, underpressure distillation thickening equipment, enrichment factor is high, less energy consumption, floor space is little, and programmable control, dependable performance, processing ease, saves labor force and reduces the advantages such as environmental pollution.

Fig. 2, the concentrated ultra-filtration equipment structural representation of using of aluminium colloidal sol depickling.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with attached Fig. 1 and 2.
Referring to Fig. 1 and Fig. 2, electrical control cubicles 14 is switched on power, each valve of controlling on pipeline enters aluminium colloidal sol depickling ultrafiltration concentration operating mode, starting ultrafiltrate pump 4 is contained in the aluminium colloidal sol feed liquid in work tank 15 in the hyperfiltration membrane assembly 6 being together in series with web member 5 on membrane stack support 16 through 1 input of stoste transfer lime, carry out the ultrafiltration work of stoste, wherein clear liquid is collected by clear liquid collection tube 7, clear liquid is input to subsequent handling by clear liquid discharging pipe 13 and processes, the turbid liquid in hyperfiltration membrane assembly 6 dope exits, be transported in work tank 15 by turbid liquid collection tube 8 and turbid liquid output tube 9, so iterative cycles, aluminium collosol concentration in stoste is improved constantly, make the water in stoste simultaneously, the small-molecule substances such as acid and salt constantly reduce, thereby obtain the low sour aluminium colloidal sol product of processing requirement.
In the time that the transmitance of hyperfiltration membrane assembly 6 is reduced to certain limit value, need to carry out clean cycle.Stop the concentrated circulation of depickling, enter cleaning pattern.Inject pure water and add clean-out system in cleaning case 3 by pure water transfer lime 12, be flushing channel state by electrical control cubicles 14 by each valve regulated on pipeline, start ultrafiltrate pump 4, scavenging solution self-stip case 3 enters in hyperfiltration membrane assembly 6 through ultrafiltrate pump 4, impurity effect in pollutent by scavenging solution and ultra-filtration membrane surface and passage, form solubility or flow composition and enter cleaning or turbid liquid, clear liquid turns back in cleaning case 3 by clear liquid collection tube 7 and clear liquid transfer lime 11, turbid liquid is inputted in cleaning case 3 by turbid liquid collection tube 8 and turbid liquid input tube 10, circulate for some time at a certain temperature, enter in solution until pollute the material of ultra-filtration membrane, stop circulation, open the delivery pipe 2 of cleaning case 3 bottoms discharges scavenging solution from cleaning case 3, ultra-filtration membrane surface affects the material of ultrafiltration performance and is removed, ultrafiltration performance must be in recovery.
