Abstract
The utility model relates to a structure of ceramic filtrating component, which is characterized in that the central hole of the ceramic film tube can be utilized as a filter side for filtration without film coating. A drainage tube is arranged at the central hole to pull the filtered liquid out. The clearance between the epoxide resin sealed central hole and the drainage tube can prevent the mixture of the filtered liquid and the material liquid. The structure is characterized in the short distance of filtered liquid going through the component, which simplifies the manufacturing technique and reduces the manufacturing cost.
Description
Technical field
The utility model relates to a kind of structure of ceramic film filtering element, and this structure has permeation liquid by the short characteristics of the distance of this element.
Background technology
The film separation process of micro-filtration, ultrafiltration contains the solute of dissolving or the liquid of suspended particulates in order to separation, and wherein the little molecule of solvent and solute sees through film, and big molecule of solute and suspended particulate tunicle are held back.
The core of film filter is a filter membrane, compares with organic film, and it is good that ceramic membrane has chemical stability, and mechanical strength is big, and anti-microbe ability is strong, and is high temperature resistant, and pore-size distribution is narrow, the separative efficiency advantages of higher.
The ceramic membrane element of industrial general application is based on the multichannel form, because the filter element membrane area of multichannel form is bigger, and the filter efficiency height, in order further to increase membrane area, the ceramic honey comb structure can be applied to ceramic filter element.The weak point of ceramic membrane element is that the liquid osmotic resistance of multi-channel structure is bigger.
The structure of the ceramic supporting body among U.S. Pat 5009781 and the US5108601 is cellular, its passage is very many, in order to reduce osmotic resistance, it must open a lot of groove water conservancy diversion, penetrating fluid is pooled to drainage trough, also will perhaps connects a drainage tube drainage by STH or fluting drainage outside in the perforate of the center of supporter, therefore, its processing technology complexity.
Summary of the invention
Problem to be solved in the utility model is to overcome the bigger shortcoming of ceramic membrane filter resistance, a kind of structure that the filter element of two per-meate side is arranged has been proposed, this structure is compared with former multichannel ceramic membrane element, has short liquid by the distance of element and less liquid osmotic resistance.
The technical solution of the utility model is: the key of membrane filtration is film, is filtered liquid and sees through film under the effect of pressure, and the more little energy consumption of resistance that liquid sees through film is more little, efficient is high more, and liquid is more little by the short more resistance of distance of supporter.Under the certain condition of the resistance of film, the structure of filter element supporter can exert an influence to the distance of liquid by supporter, and now employed ceramic membrane great majority all are the multichannel forms in the engineering, employing be the mode of cross-flow filtration.Liquid enters from an end of film pipe, trapped fluid flows out from the other end of film pipe, penetrating fluid sees through film and supporter, and to be penetrated into per-meate side be the outside water outlet of film pipe, because multichannel design feature, the liquid that is in film tube hub position will could arrive per-meate side through film and one section very thick supporter, this has just increased liquid and has arrived the distance of per-meate side, thereby has increased the resistance of liquid by supporter.
The utility model has proposed to increase a per-meate side at this problem, reduces the supporting body structure of liquid infiltration distance.Concrete technical scheme is: a kind of ceramic film filtering element, the central duct 2d that it is characterized in that ceramic-film tube 3 does not film, as the filtration and infiltration side, this per-meate side duct directly prepares when the extrusion molding of ceramic membrane element, there is a drainage tube 1 that permeation liquid is drawn at central duct 2d place, and, prevent that permeation liquid from mixing with material liquid with the gap between binding agent center seal duct 2d and the drainage tube 1.
The structure of wherein said ceramic-film tube 3 is multichannel ceramic-film tube or ceramic honey comb film pipe; Described drainage tube 1 is ceramic of compact, engineering plastics or stainless steel material.
Wherein said drainage tube 1 can be on a termination of membrane component, and the other end is blocked and sealed with stopper, and perhaps both sides all connect drainage tube.
The structure of this filter element as shown in Figure 1.
Liquid infiltration routes in the multi-channel membrane tube as shown in Figure 2, can be divided into 4 layers to the passage of multi-channel membrane tube, represent by sequence number a, b, c, d respectively, penetrating fluid in a layer arrives per-meate side through the shortest distance, be b, c, d layer then successively, wherein the permeation liquid in the passage of film tube hub to arrive per-meate side will be through the longest distance, the osmotic resistance meeting is very big like this, almost do not have filter effect, flux is little.
As shown in Figure 3, if filter without central duct, but as the per-meate side drainage, the efficient in c layer hole will improve greatly so, though the present invention has abandoned the filter area of central duct, but improved the utilization rate in c layer hole greatly,, improved flux so generally speaking reduced osmotic resistance.
This structure also can be applicable to ceramic honey comb film pipe, and is similar with multi-channel membrane tube, the liquid infiltration routes in the film pipe of ceramic honey comb structure as shown in Figure 4, the liquid infiltration routes is as shown in Figure 5 in the structure of the present utility model.
Need add a drainage tube to central duct at the central duct place as a per-meate side, this drainage tube can use materials such as ceramic of compact pipe, engineering plastics, stainless steel tube, adopts the gap between organic encapsulant sealing drainage tube such as epoxy resin, polyurethane and the passage can reach the effect of sealing fully.
This membrane component can be applied to micro-filtration, the ultra-filtering element of cross-flow filtration device.The material of supporter and film is the mixture of pure aluminium oxide, zirconia, titanium oxide or above-mentioned material and cordierite, mullite or the like.
The utility model is mainly used in water treatment field, and the preprocessing process that is applied to reverse osmosis process also can be used for other various liquid filterings.
Beneficial effect:
1, shortened the distance of liquid from feed side arrival per-meate side.Multi-channel structure has only a per-meate side, be exactly the film pipe outside, in the multi-channel structure, the distance that the liquid in the central passage arrives per-meate side is the longest, the resistance maximum.The present invention draws penetrating fluid from the central passage of film pipe, the film pipe is with regard to many per-meate side like this, liquid is many again selections in arriving the path of per-meate side, according to the minimum principle of energy, liquid always can select the shortest distance to arrive per-meate side, in structure of the present invention, it is the longest to have become the distance that the liquid in the passage in the middle of exosmosis side and the interior per-meate side will pass through, this distance and former multichannel reduced in comparison many.
2, compare with United States Patent (USP), structure of the present utility model has had centre bore during in extrusion molding at the multichannel supporter, if an external drainage tube, and also realization easily of sealing fully.Also be the same for the ceramic honey comb structure, because used the arranging of honeycomb hole of the utility model is the center diverging, so has extruded when extrusion modling in middle hole, perforate in addition also needn't be slotted.So for machine-shaping has reduced difficulty, and can realize the membrane area that requires by the increase membrane module.
3, easy manufacturing process has reduced production cost.
