Description
Technical field
The utility model relates to the membrane separation technique field, relates in particular to a kind of configuration of inorganic membrane element.
Background technology
It is that a kind of operation is relatively simple, the low separating technology that consumes energy that film separates, and can reclaim and recycle the component in mixture in principle, thereby be widely used in bioengineering, oil, chemical industry, metallurgy, medicine and other fields.Film separates to be realized by membrane module, and its core is the filter membrane element.With organic film, compare, chemical stability is good, mechanical strength is large, anti-microbe ability is strong, high temperature resistant, pore-size distribution is narrow, the separative efficiency advantages of higher as ceramic membrane has for inoranic membrane, but can't as organic film, by folding mode, improve membrane area/volume ratio (the membrane filtration area in the elementary membrane component size).For improving membrane area/volume ratio, the currently available technology ceramic membrane is to adopt the mode (as 7,19 and 37 passages) that increases the duct number mostly, or uses ceramic honey comb film, hollow fiber ceramic membrane.
Yet, in prior art multi-pore channel/ceramic honey comb film configuration, discharge problem for solving penetrating fluid, need to consider the spread configuration of infiltration lane, so just, make the ceramic honey comb film 1/3 even half passage need be for the discharge of penetrating fluid, thereby the effective filtration area of ceramic honey comb film that caused reality to reduce.For hollow fiber ceramic membrane, employing will separate the pattern that rete is prepared in the doughnut film outer surface, can obtain higher membrane area/volume ratio and bear higher intermembranous pressure, but this pattern need to adopt the external-compression type membrane filtration pattern (to be about to pressure-acting in feed liquid, feed liquid flows at film outer surface, penetrating fluid flows out in the film internal channel), therefore exist following technical problem: it is different that (1) and organic film have good morphotropism, and the violent turbulence of feed liquid makes to have than big L/D ratio and hangs down the easy fracture of inorganic hollow fibers ceramic membrane of morphotropism.Especially for meeting the needs of membrane module, usually inorganic hollow fibers ceramic membrane two ends are fixed to the caused disturbance of feed liquid and the destruction that produces is stronger.(2) generally speaking, hollow-fibre membrane is arranged tightr, and the disturbance of feed liquid easily causes rubbing, colliding between the film pipe, thus the destruction that causes separating rete.Therefore, the contradiction between the configuration of prior art hollow fiber ceramic membrane and its filtered model is unusual distinct issues.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of inorganic membrane element with high membrane area/volume ratio is provided, when effectively improving the membrane area/volume ratio of inoranic membrane, effectively solve the configuration of doughnut inoranic membrane and the contradiction between its filtered model.
The purpose of this utility model is achieved by the following technical programs:
A kind of inorganic membrane element with high membrane area/volume ratio that the utility model provides, comprise the honeycomb inoranic membrane, and described honeycomb inoranic membrane consists of porous supporting body and filtration duct, and the inner surface in described filtration duct is for separating rete; In addition, in the filtration duct of described honeycomb inoranic membrane, be provided with the doughnut inoranic membrane, described doughnut inoranic membrane is hollow columnar and has internal channel and as the outer surface that separates rete.
The utility model inorganic membrane element, separate rete and be distributed in the outer surface of doughnut inoranic membrane and the inner surface in its filtration duct of honeycomb inoranic membrane, be that passage between doughnut inoranic membrane outer surface and honeycomb inorganic membrane filtration duct is the feed liquid passage between the two, the porous supporting body of the internal channel of doughnut inoranic membrane and honeycomb inoranic membrane is permeate passageway.Like this, just greatly improved the membrane area/volume ratio of inoranic membrane, simultaneously, because the filtration duct of honeycomb inoranic membrane gives the supporting of doughnut inoranic membrane, the fracture of doughnut inoranic membrane be can avoid, thereby the configuration of doughnut inoranic membrane and the contradiction between its filtered model are conducive to solve.
For further reducing the impact of feed liquid turbulence on the doughnut inoranic membrane, its inwall that filters duct of the described honeycomb inoranic membrane of the utility model inorganic membrane element contacts with the doughnut inoranic membrane.Can take following concrete measure: described honeycomb inoranic membrane is provided with at least one doughnut inoranic membrane in its single filtration duct, only single or assemblys many doughnut inoranic membranes are filled in the filtration duct of honeycomb inoranic membrane as much as possible, make the space that keeps less between the two, increase the supporting of honeycomb inorganic membrane filtration duct to the doughnut inoranic membrane.
In such scheme, for ease of end-blocking, stretch out outside the honeycomb inoranic membrane at the two ends of doughnut inoranic membrane described in the utility model; Described doughnut inoranic membrane one end is provided with the end-blocking thing in internal channel, and its other end is provided with the end-blocking thing between the outside.
The utlity model has following beneficial effect:
(1) effectively improved the membrane area/volume ratio of membrane component
In the configuration of the utility model inorganic membrane element, in identical volume, for the honeycomb inoranic membrane, its all filtration duct inner surface is effective membrane area.Although the discharge resistance of penetrating fluid increases to some extent, membrane area is 1.3～1.5 times of original honeycomb inoranic membrane configuration, and total permeation flux increases on the contrary.In addition, the doughnut inoranic membrane add the effective area that has further increased membrane filtration, the membrane area/volume ratio that makes the utility model inorganic membrane element configuration is 2～5 times of conventional film configuration.
(2) efficiently solve the film configuration of doughnut inoranic membrane and the contradiction between filtered model
In the configuration of the utility model inorganic membrane element, the doughnut inoranic membrane contacts as far as possible with the honeycomb inoranic membrane, has reduced because of the caused doughnut inoranic membrane of feed liquid disturbance resonance problem, has avoided the fracture of doughnut inoranic membrane.Simultaneously, under the constraint in honeycomb inorganic membrane filtration duct, feed liquid flows along doughnut inoranic membrane axial direction, thereby has also reduced the impact of feed liquid turbulence on the doughnut inoranic membrane.
(3) there is existing equipment adaptability preferably
The utility model, for the honeycomb inoranic membrane, adopts the feed liquid circulation pattern, therefore can be applicable to existing most of membrane filter systems; For the doughnut inoranic membrane, the filtration duct of honeycomb inoranic membrane is equivalent to outer die pressing type, without feed liquid is additionally added to supercharging equipment, thereby can effectively reduce the film device cost.
