Abstract
The utility model relates to a dynamic membrane water treater, which is composed of an air dissolving tank 3, a dynamic membrane filter 8, a circulating reflux hopper 16, and a circulating pump 15, wherein, the inner part of the dynamic membrane filter 8 is provided with a dynamic membrane pipe 11, and the inner wall is made with a dynamic membrane; when the dynamic membrane pipe 11 is blocked by a filtering cake, a valve V1 is closed, a valve V7 is opened, as the pressure relief is suddenly carried out, air dissolved in sewerage is suddenly released, and the filtering cake is caused to become loose; then, flush water is pumped from the circulating reflux hopper 16 into the dynamic membrane filter 8 through the circulating pump 15 to flush the dynamic membrane pipe 11, and the filtering residue is flushed into the circulating reflux hopper 16 and is treated. The utility model can be continuously operated, and the dynamic membrane does not need prepared repeatedly.
Description
The utility model relates to the Dynamic Membrane water treatment device.
Dynamic membrane filtering is having bigger superiority than fixing film aspect preparation and the working cost, but Dynamic Membrane is (generally showing as filter cake blocks) when taking place to pollute, if adopt the back flushing of similar fixedly film, then Dynamic Membrane is simultaneously destroyed when flushing, this just needs heavy duplicating film, consequently preparation cost rises, and operation can not be continuous, thereby limited Dynamic Membrane greatly in industrial application.
The purpose of this utility model provides a kind of Dynamic Membrane water treatment device that can easily remove filter cake and don't destroy Dynamic Membrane.
The technical solution of the utility model is as follows:
A kind of Dynamic Membrane water treatment device, it is made up of dissolving, dynamic membrane filtering device, pump around circuit bucket and recycle pump.Inlet pipe is arranged on the dissolving, and inlet pipe stretches into the bottom of dissolving, and it is not held can gas distributor.Into waste pipe is arranged at the top of dissolving, the sewage blow-off pipe is arranged at the bottom, the sewage blow-off pipe links to each other with dynamic membrane filtering device bottom bulkhead, the dynamic membrane filtering device is a shell and tube strainer, the vertical installation, the base material of Dynamic Membrane pipe is by micropore ceramics, plastics, glass, or poromerics such as metal is made, its inwall is shaped on Dynamic Membrane, "+" word filtering outlet is arranged on the upper cover of dynamic membrane filtering device, it is communicated with dissolving through valve and filtering and concentrating water reflux pump, crosses filterable clear water through the Dynamic Membrane pipe in the dynamic membrane filtering device and discharges through the pure water inlet valve from the pure water inlet on the dynamic film filter sidewall.The upper cover of dynamic membrane filtering device has the wash-down water circulation port, it is communicated with the pump around circuit bucket through the wash-down water outlet valve, pump around circuit bucket bottom is doline, rinse water import and flocculation agent import are arranged at its top, there is pipeline to be communicated with on the sidewall through the lower cover of recycle pump with the dynamic membrane filtering device, the funnel-shaped bottom portion of pump around circuit bucket has the bucket outlet valve, and it is connected with mud slurry outlet pipe.
A plurality of eddy flow are housed in the inside of above-mentioned Dynamic Membrane pipe, and it is fixed on the axis by the eddy flow plate of twisted shape forms, the spacing of eddy flow be the Dynamic Membrane pipe internal diameter 2-5 doubly.
Pure water inlet valve at the dynamic membrane filtering device can be connected with under meter, is connected with electric signal process unit on the under meter, with the automatic switchover that realizes filtering or washing.
The utility model is following operation:
Sewage enters dissolving through advancing waste pipe, from inlet pipe the sewage that air is pressed into to the 3-5Kg/cm2 dissolving is pressed into the dynamic membrane filtering device through the sewage blow-off pipe simultaneously, sewage filters clear water through the Dynamic Membrane pipe and discharges from the pure water inlet valve, part of contaminated water is through "+" word filtering outlet, the condensed water reflux pump is returned in the dissolving after filtration, constantly filter, when having filter cake, blocks the Dynamic Membrane pipe, the effusive clear water flow of pure water inlet valve reduces, "+" word filtering outlet valve and filtering and concentrating water reflux pump and the sewage blow-off pipe valve that can close dynamic membrane filtering device top this moment, open the wash-down water outlet valve, because step-down suddenly, molten gas is separated out from water, make filter cake become loose, open recycle pump simultaneously, clear water is squeezed into from dynamic film filter lower cover, filter cake in the flushing Dynamic Membrane pipe, filter residue is poured in the pump around circuit bucket, flushing finishes, close wash-down water outlet valve and recycle pump, open "+" word filtering outlet valve and filtering and concentrating water reflux pump, proceed water treatment, be added to flocculation agent in the pump around circuit bucket by the flocculation agent import this moment, make the suspended substance in the sewage be deposited to the interior leakage capitiform bottom of pump around circuit bucket, discharge through bucket outlet valve and mud slurry outlet pipe then, the upper strata clear water is used for next round flushing Dynamic Membrane pipe.Dynamic Membrane pipe with eddy flow, its filter cake are difficult for forming and block, and the filter cake that forms is rinsed easily.
Adopt Dynamic Membrane treatment unit of the present utility model, the filter cake in the Dynamic Membrane pipe can rinse out easily, and Dynamic Membrane is not destroyed, and therefore can move continuously and need not repeat to make Dynamic Membrane.
