Description
Technical field
The utility model relates to liquid filtering field, is specifically related to a kind of fluid filter system.
Background technology
Liquid filtering refers to and the liquid containing impurity is flow through the filter medium with certain porosity, and the impurity in liquid is trapped within dielectric surface or inner and remove.Use comparatively general filter type to comprise two kinds in current liquid filtering, one is terminal type liquid filtering, and another kind is cross-current type liquid filtering.Terminal type filter element is adopted in terminal type sedimeter, go out in entering beyond stoste to be filtered or in the form entering to go out pass through filter element, impurity in stoste to be filtered is intercepted at filter element surface, after filtering a period of time, filter element surface can deposit one deck filter cake, the filter efficiency of filter element is caused to reduce thus, regenerate to make filter element, need the filter cake of scheduled shut down cleaning and filtering element surface, this kind of filter in use needs repeatedly to stop, make production process discontinuous, also larger economic loss can be caused time serious.What adopt in cross-current type sedimeter is cross-flow filtration element, stoste to be filtered also can wash away filter element surface when being filtered by this kind of filter element, after filtration, the clear liquid of gained is concentrated and is discharged, after filtration, remaining concentration stock solution reenters in cross-flow filtration element after discharging and filters under circulating pump effect, realize the circulating filtration of concentration stock solution in cross-flow filtration element, this kind of filter can realize continuous seepage in filter, but its process circulating pump needs to overcome the circulating filtration that larger resistance realizes concentration stock solution, considerably increase production cost thus.
Utility model content
Technical problem to be solved in the utility model is that providing a kind of can realize continuous seepage and the fluid filter system of reduction production cost.
In order to solve above-mentioned prior art problem, the utility model is achieved through the following technical solutions:
The utility model fluid filter system comprises at least double-filtration unit, filter is provided with in described filter element, filter has the stoste import entered for stoste to be filtered, for crossing the purified liquor outlet that cleaner liquid is discharged and the stoste outlet of discharging for the concentration stock solution formed when filtering, purified liquor outlet connects clear liquid gathering-device, the stoste outlet of each filter element middle filtrator is connected with the stoste import of adjacent subordinate's filter element middle filtrator, the stoste import of the filter in chopped-off head filter element connects raw liquor pump, the stoste outlet of the filter in final stage filter element connects stock solution collection device.Stoste to be filtered realizes continuous seepage step by step by above-mentioned multistage filtering unit and filters, improve filtering accuracy, after filtration, remaining concentration stock solution enters into subordinate's filter element continuation filtration under the effect of raw liquor pump, continue filtration kinetic energy, and do not need in filter process additionally to overcome resistance, thus reduce plant energy consumption, decrease production cost.Concentration stock solution collecting pit, makes the concentration stock solution of discharging from whole fluid filter system obtain centralized collection thus, is convenient to thus focus on it.
As the further improvement of aforesaid liquid filtration system, the consistent and quantity of the filter specification of filter element at different levels is successively decreased step by step.The clear liquid filtered is had to export in every grade of filter element, therefore the concentration stock solution amount that every grade of filter element middle filtrator receives from upper level is reducing gradually, in order to more reasonably distribute the number of filters of every grade of filter element, according to the principle that above-mentioned concentration stock solution amount reduces gradually, should ensure that the filter area of every grade of filter element is successively decreased step by step, when each metre filter area is certain, the number of filters of every grade of filter element is successively decreased step by step.
