Abstract
The utility model relates to a multi-stage homogeneity anti-granularity filter for filtering and processing water. The multistage homogeneity anti-granularity filter is mainly composed of multistage filter chambers with a single filter layer, and the filter chambers are connected in series. Filter materials in each filter chamber are homogeneous materials of which the particle diameters are uniform, and the sizes of the particle diameters of filter materials in different filter chambers are corresponding to the sequence that raw water is fed into the filter chambers. The utility model has the advantages that the structure is simple, and the utility model can chronically preserve the best anti-granularity filtering effect. The utility model is suitable for being used for filtering water supply for cities and countries, and is also suitable for being used for processing industrial sewage and domestic sewage.
Description
The utility model belongs to water treatment field.
Be used at present water quality is carried out the filtration treatment device; effect is preferably a kind of anti-granularity filter; this filter is to place which floor filtering material in a container; the particle diameter size of each layer filtering material is arranged by the order from the upper strata to the lower floor; former water portion's inflow from container with the needs filtration; filter grain through the major diameter particle filters earlier; pass through the small diameter particles media filtration again; flow out from the container bottom at last; has filter effect advantage preferably; but this kind filter is when recoil cleaning and filtering material; putting in order of filtering layer can be upset; become granule on the upper strata; the phenomenon that bulky grain mixes in lower floor or size particles greatly hinders the raising that contains dirty ability and effluent quality, has lost the advantage of anti-granularity.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and designing does not a kind ofly influence putting in order of filtering layer when the recoil cleaning and filtrating equipment, makes filter can keep the anti-granularity filter of multistage homogeneous of optimum efficiency for a long time.
The anti-granularity filter of multistage homogeneous of the present utility model, comprise filter bed and former water mixed flocculation device and recoil cleaning water tank, major measure is the filter chamber composition that the filter bed of single-stage multi-filtering layer is changed into the multistage single filtering layer that is connected in series, filter course in the filter chambers at different levels is made up of the uniform filtering material of the same race of particle diameter, the size of filtering material particle diameter is corresponding with the sequencing that former water enters filter chamber in the different filter chambers, raw water inlet and air vent and venting valve are arranged at the top of filter chambers at different levels, water dispensing board and recoil delivery port are arranged at top, the middle part has filtrate to load lid, there is water collection sheet the bottom and filters out the mouth of a river, the recoil water inlet is arranged at the bottom, filtering material is enclosed on the water collection sheet from loading lid, its annexation is: the raw water inlet of first order filter chamber is connected with former water mixed flocculation device, the filtering out the mouth of a river and filter out water pipe and be connected of afterbody filter chamber, the mouth of a river that filters out of other filter chambers at different levels is connected with the raw water inlet of next stage filter chamber respectively successively, the recoil water inlet of filter chambers at different levels cleans water tank through water pipe and recoil and is connected, and the recoil delivery port is connected with the recoil outlet pipe.For the ease of control, can filter chambers at different levels filter out the mouth of a river and recoil water inlet and recoil delivery port and valve is housed between the water pipe connecting separately, if this valve magnetic valve can be connected with computer and use the computer centralized Control.The filter chamber sum of series of this device filtering material at different levels can and be handled index and decide according to pending former aqueous nature.
Accompanying drawing 1 is the structural representation of three grades of anti-granularity filters of homogeneous in the utility model;
Accompanying drawing 2 is vertical views of accompanying drawing 1.
Referring to accompanying drawing, filtering material 8 is built 7 filter chambers of packing into from loading, during the equipment operation, that opens filter chambers at different levels filters out penstock 11, former water after dosing reaction flocculation enters filter chambers at different levels successively by water inlet pipe, open simultaneously venting valve 2 successively, after bleeder pipe 1 drains air in the filter chamber valve 2 is closed, equipment puts into operation.At this moment, pending former water flows to from the water inlet 3 of first order filter chamber, behind water dispensing board 4, filtering material 8 and water collection sheet 9, flow to the next stage filter chamber through valve 11 again after flow out at the mouth of a river 10 and further filter from filtering out, from the filtered water that the mouth of a river 11 can obtain standard up to specification that filters out of afterbody filter chamber.When the against regulation standard of effluent quality index (or the pressure differential between water inlet and the water outlet surpass setting), show that filtering material absorption (or dam to dirt) amount has reached limiting value, should stop into water, cleaning need recoil, make filtering material recover strainability, when recoil is cleaned, close former water inlet valve and filter out penstock 10, open backwashing intake valve door 13 and recoil flowing water Valve 5, recoil water enters from the filter chamber bottom through backflushing water intake pipe 12, and from recoil outlet pipe 6 outflows on filter chamber top, filter chambers at different levels can clean simultaneously, also can clean respectively, recoil can drop into next circular flow after cleaning and finishing.
The utility model is owing to load homogeneous filtering material from coarse to fine respectively in the filter chambers at different levels, promptly use the filtration order of anti-granularity, former water at first passes through the coarse granule media filtration, flocculate bigger in the former water is at first held back, pass through thin again and fine grained media filtration, respectively less flocculate and microfloc are trapped in the filtrate, filter beds at different levels all can be played a role preferably, avoided the big very fast gap of flocculate to stop up with the fine grained filtrate, and the gap of coarse granule filter is more greatly to the inoperative shortcoming of trickle flocculate, preferably resolve the problem of layering of filter chamber layer and backwash contradiction again because of this device, filter chambers at different levels can not be interacted when recoil cleaning and filtering material, so can keep best filter effect for a long time, this device also has simple in structure, advantages such as fabrication and installation are convenient, be applicable to that urban water supply and rural area central water supply filter, and also are applicable to the processing of trade effluent and sanitary sewage.
