Membrane filtering machine
One, technical field
The utility model relates to a kind of filter, specifically a kind of Membrane filtering machine.
Two, background technology
The research of membrane filtration and use are existing for many years, are engaged in film filtering element research, the mechanism or the enterprise that produce and use the manufacturing enterprise of these element combinations produce Membrane filtering machines also a lot.The technical development of film filtering element is very fast, the price of film filtering element also reduces greatly, but the Membrane filtering machine technology does not have too big progress, the equipment of producing mainly due to prior art, can not give full play to the performance of film filtering element, can't improve filter capacity to greatest extent, prolong film filtering element stream time and service life, thereby can't reduce user's use cost, make the scope of application of membrane filtration further not enlarge.The reason that produces the problems referred to above mainly is a prior art does not have breakthrough on the acquisition of technology to the regeneration of membrane component.
What present most of Membrane filtering machine adopted is the backwash renovation process, and its workflow is as follows, sees Fig. 2:
Stoste is filtered by raw liquor pump 4 input membrane modules 2 from original fluid container 1, and the clean liquid after the filtration enters filtering tank 3, returns original fluid container 1 after the stoste of process membrane module 2 is concentrated; After membrane module work a period of time, owing to increase gradually attached to solid phase impurity on the filtering surface, the rate of filtration is more and more slower, must stop to filter, and the regeneration that recoils is handled; Backwashing pump 9 extracts the clean sap cavity that the clean liquid of fraction is squeezed into membrane module from filtering tank, oppositely, will dash from filtering surface, enter original fluid container through the concentrate pipe attached to solid phase impurity on the membrane filtration face by the membrane filtration face, the membrane filtration face obtains regeneration, can carry out the filter operation of following one-period.
There is following shortcoming in this periodicity backwash renovation process:
1, used the clean liquid of part as counter-flushing liquid, this part liquid also will carry out filtration treatment once more, thereby has reduced the complete machine disposal ability, has increased energy consumption; As use other liquid as counter-flushing liquid, before recoil or with the liquid emptying in the membrane module, or, cause the material waste with the mixing of the liquid backwash liquid in the membrane module; After the counter-flushing liquid operation is finished, also must the fluid discharge in the membrane module is clean, just can carry out the filter operation of following one-period, reduced the effective time, overall efficiency is descended;
2, in a filter cycle, some is squeezed in the filtering micropore by compacting gradually attached to the solid phase impurity on the filtering surface, this can not be come out by super backflush, the filter capacity of membrane module decreases, along with increasing of the micropore that loses filtration, these filtering micropores will be stopped up fully, have lost filtration, and whole membrane component finally will be scrapped;
3, the life-span of membrane module is depended on technical parameter, global design level of former liquid-solid phase impurity content, backwash process or the like.For the more stoste of solid phase impurity content, must shorten filter cycle, increase the backwash number of times and just can keep filter operation, at this moment the life-span of membrane component will shorten greatly.
In a word, the backwash renovation process of membrane filtration has reduced the operating efficiency of membrane module, has increased energy consumption, reduces the life-span of membrane module, has limited the scope of application of membrane filtration.Many materials that must improve filtering accuracy with membrane filtration are arranged, because impurity is more, the membrane component life-span is too short, can not directly use membrane filtration, makes the application of membrane filtration be very restricted.
