Description
Utility model relates to ceramic filter tube and the filter that produces the waste water recycling in a kind of titanium dioxide manufacture process.
In the Titanium White Production By Sulfuric Acid Process process, there are a large amount of acid pickles and waste water to produce, and contain available metatitanic acid particulate and titanium dioxide particulate in acid pickle and the waste water respectively.The present traditional sedimentation process of the general more employing of processing to titanium dioxide waste water, because metatitanic acid particulate and the tiny sinking speed of titanium dioxide particulate are slower, thereby sedimentation process not only floor space is big, and separative efficiency is low, reclaims not exclusively the sludge dewatering difficulty, it is big to handle back body refuse amount, limited the recycling of spent acid and water, gone out aqueous suspension after the separation and be difficult to reach discharge standard, contaminated environment.For overcoming the deficiency of above-mentioned prior art, Chinese patent 88211495 discloses a kind of continuous concentration seperator, but still is to adopt filter plate, filter cloth to filter, and the low labour intensity of efficient is big.The porous ceramic pipe of employing isolated by filtration is from inside to outside also arranged, and separating particles is delayed in the screen pipe, and filter cake is discharged difficulty, causes the obstruction of screen pipe easily, and is especially very undesirable to the isolated by filtration effect of fine particle.Thereby porous ceramic filter pipe generally is not suitable for the many and small isolated by filtration of suspended particulate medium, and the titanium dioxide waste water of and fine particles big for liquid-solid ratio causes screen pipe to stop up easily.Therefore the titanium dioxide wastewater treatment becomes the Industrial Wastewater Treatment a great problem.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provide metatitanic acid particulate and titanium dioxide particulate in a kind of effectively isolated by filtration titanium dioxide waste water, and it is little to have filtration resistance, and the separative efficiency height is difficult for stopping up the caducous ceramic filter tube of filter cake.
Another purpose of utility model is to provide a kind of filter of using above-mentioned ceramic filter tube filtration treatment titanium dioxide waste water.
Utility model first purpose realizes that main the improvement is to cover in the porous ceramic filter pipe periphery to carry one deck inorganic ceramic membrane, forms the polymer-coated ceramic powder screen pipe with compound structure.Specifically, the ceramic filter tube of particulate comprises porous ceramic pipe in the utility model separating titanium white powder waste water, it is characterized in that said porous ceramic pipe is covered with the aperture inorganic ceramic membrane working lining directly thin than the porous pore outward.
Utility model composite ceramics screen pipe, because the pore footpath, the more hole of inorganic ceramic membrane aperture of periphery is little, so isolated by filtration mainly relies on the inorganic ceramic membrane working lining, and the porous ceramic pipe of internal layer mainly works the inoranic membrane effect of supporting, and is called supporter in this patent.According to the size of metatitanic acid particulate in the titanium dioxide waste water, the inorganic ceramic membrane average pore size is made as 1-5 μ m, inoranic membrane work bed thickness 20-50 μ m.For reducing filtration resistance, the inorganic ceramic membrane aperture is from strengthening inwards outward, in the thickness direction distribution gradient.The visual inoranic membrane thickness of supporter average pore size, than the big 4-10 of inoranic membrane average pore size doubly, supporting mass thickness of pipe wall 5-12mm.Look the isolated by filtration frame mode, the polymer-coated ceramic powder screen pipe can an end seals an end and opens wide, also can open at both ends.
Another purpose of utility model realizes, is to make filter element with above-mentioned polymer-coated ceramic powder screen pipe.Specifically, the utility model filter, form by filtration barrel body and built-in filter element, the be draped porous plate of screen pipe of said filtration barrel body is separated into filtering area and exhalant region, it is characterized in that said filter element forms side by side for the polymer-coated ceramic powder screen pipe that is covered with the aperture inorganic ceramic membrane working lining directly thin than the porous pore by porous ceramic pipe outward and forms.
Description below in conjunction with a non-limiting embodiment further specifies utility model.
Fig. 1 is the multiple film ceramic filter tube organigram of utility model embodiment.
Fig. 2 is a utility model embodiment titanium dioxide effluent filter structural representation.
Embodiment: referring to Fig. 1,2, the polymer-coated ceramic powder screen pipe is composited by tubular type porous ceramics supporting layer 1 and inoranic membrane working lining 2, and the screen pipe lower end closed is unidirectional outlet.Supporting layer thickness of pipe wall 5-8mm wherein, average pore size is 18 μ m, inoranic membrane work bed thickness 20-30 μ m, the top layer average pore size is 1.5-2 μ m.The filter element that filter is made up of filtration barrel body 7 and built-in multiple film ceramic filter tube 6 is formed.The be draped porous plate 4 of screen pipe of cartridge filter inner chamber is divided into little go out space, liquid zone 7.1 and big filtering area space 7.2, goes out the liquid zone and is provided with liquid outlet 3, and filtering area is provided with charging aperture 8, exhaust outlet 5 and controlled row's filter cake (slag) mouthfuls 9.
During isolated by filtration, waste liquid pressure is delivered to the filtering area space, because the barrier effect of the inorganic ceramic membrane minute aperture on screen pipe surface, high pressure makes that particulate is blocked in polymer-coated ceramic powder screen pipe appearance in the waste liquid and forms cake layer, clear filtrate behind the removal particulate is by filtering tube wall by the uncovered liquid zone that drains into out of screen pipe, discharge through liquid outlet, filter process gas is discharged by exhaust outlet.When filter cake accumulates to certain thickness, filtration resistance increases, stop the pumping waste liquid, open slag-drip opening, the compressed air of being sent into by the top is come off the filter cake attached to the screen pipe periphery by the blowback of filtration openings end, discharges from slag-drip opening, gas is then discharged from exhaust outlet, thereby reaches separating of acid solution and metatitanic acid particulate and water and titanium dioxide particulate.Can obtain comparatively pure metatitanic acid and titanium dioxide particulate and acid solution and water by separating, reuse respectively.
Utility model is not limited to the foregoing description, supporting layer, especially working lining average pore size can adjust according to particle requirement in the separated titanium dioxide waste water, working lining outermost layer aperture can doubly be determined by the 2-5 of minimum separation particle diameter, specifically decided by waste strength.Filter cake comes off and also can adopt the chimney filter mode of vibration to realize, these unsubstantialities change all true novel protected scope of using.
Utility model is because screen pipe adopts the bigger porous ceramic pipe in aperture to make supporting layer, and the aperture is tiny and the inoranic membrane of distribution gradient is made working lining composition composite ceramics screen pipe, and makes the filter that filter element is formed with this screen pipe.Thereby have a little efficient height of filtration resistance, and good separating effect and thoroughly, screen pipe is difficult for stopping up, long service life, separating particles is thin, outer filter mode filter cake characteristics such as easily come off.Thin inoranic membrane working lining is because the crane span structure effect, can the isolated by filtration minimum grain size be the particulate of working lining surface average pore size 1/5-1/2, not only metatitanic acid and titanium dioxide can all be recycled in the waste water, and the comparatively pure spent acid waste water that obtains after separating also can be directly used in reuse, both saved resource preferably, significantly reduced environmental pollution again, this difficult problem of liquid waste processing in the production process of titanium pigment of having determined preferably is situated between.
