Description
Technical field
The utility model relates to cross-flow filtration equipment.
Background technology
Filter element filtering is divided into end-filtration and cross-flow filtration.Stoste when adopting end-filtration (liquid before filtering) does not produce face and flows on the filter membrane surface, so the cake layer progressive additive on the filter cycle lining endothelium, and filtration yield reduces rapidly along with the increase of filtration time, and the backwash cycle is shorter.Stoste can flow along face with certain speed when adopting cross-flow filtration, become clean liquid (liquid after promptly filtering) in this process behind the pressured difference infiltration of a part of stoste filter membrane, and liquid being filtered does not continue to flow to become concentrate and be back to circulate in the former liquid pool along face, therefore filter cycle, lining endothelium only formed a small amount of filter cake, filtration yield is along with the increase of filtration time slowly reduces, and the backwash cycle is longer.Because the filter type of end-filtration and cross-flow filtration is different, therefore there is significantly difference in the structure of existing ultimate filter and cross-flow filter.
But no matter be ultimate filter or cross-flow filter, element kit wherein all is a key equipment of realizing its filtration.A kind of structure of known filter element assembly for cross-flow filtration mainly comprises the container that is provided with stoste inlet, clean liquid outlet and concentrated solution outlet, be provided with tubular element in this container, the space that is positioned at this tubular element outside in the container becomes the clean sap cavity that holds filtration back liquid, and tubular element inside then is provided with the flow channel of stoste.The described stoste inlet in back, clean liquid outlet and concentrated solution outlet are installed to communicate with feed pipe, discharge nozzle and the return duct of filter respectively.Stoste is pressed in the pipe of tubular element through the stoste inlet during filtration, and with certain velocity axis to the filter membrane surface of flowing through, the pressured difference of part stoste is penetrated in the outer clean sap cavity of pipe becomes clean liquid, and by clean liquid outlet discharge, liquid being filtered does not then continue to flow to concentrated solution outlet and finally being back to by return duct in the former liquid pool at inner axial tube, the stoste in the former liquid pool is pressed into the stoste inlet by pump at last again and circulates.
The tubular element that above-mentioned this element kit adopted is a single layer structure, and the area of passage of filter core is fully by the decision of the size of filter core, so the restriction that is subjected to the filter core size of the filter capacity of this element kit is difficult to the state that reaches desirable.Especially for accurate micro-filtration core material such as the intermetallic compound porous material for core of aperture at 0.3～30 μ m, the filter capacity of this element kit is still waiting to improve.
