Description
Technical field
The utility model relates to the filtration processing equipment of water, refers in particular to urban water supply process, industrial water supply process, and a kind of open type bidirectional flow filter plant of the engineerings such as mark transformation is carried by Treated sewage reusing process and sewage treatment plant.
Background technology
In water filtration device, various types of filter plant is a feast for the eyes, these filter plant major parts adopt gravity filter, namely water (flow) direction from the top layer of filtrate by the bottom layered filtration of Action of Gravity Field to filtrate, and on filtering fabric, general upper strata is fine filtering material, lower floor is coarse media, this kind of filter plant filters industry at each a long time ago and is well applied, but in actual filtration, upper strata fine filtering material retains dirt and will to reach capacity very soon state, cut pollution layer and start downward transfer, lower floor is the coarse filtration bed of material that hole is larger, the effect retaining dirt cannot be met, one deck that the filter material layer effectively utilized in thick filter material layer only has surface very thin, be difficult to meet the good effect of effluent quality.At present, in water treatment filtering equipment, filtrate is existing adopts homogeneous particle filtrate, solve the waterpower layered filtration phenomenon under gravity current for the moment, but under the filtration backwash effect of gravity current, the collision between particulate material, friction, with the passing of time also will form the filter material layer of particle diameter inequality.
Chinese patent ZL201320865207.6 discloses a kind of open type double filter, is applicable to urban water supply process.Be made up of two different filter elements, be connected by the two filters on central dividing plate.Filter type is gravity filtration, namely current after the granule filter material coarse filtration layer of upper strata again through the water outlet of lowermost fibre filtrate filter bed of essence filtering emission, effluent quality is better, but during backwash, backwash current are the inverse process filtered, and namely the backwash water of washed fiber filtering rinses granule filter material again, can not realize two-layer independent backwash, consuming time longer, there is the problem of classification in the upper strata granule filter material after same backwash.
Utility model content
The utility model is intended to solve above-mentioned filter plant Problems existing in practical implementation, and provide a kind of rational in infrastructure, easy to operate, weight is little, with low cost, and filtrate is easily entered, the open type bidirectional flow filter plant of good maintenance.
In order to reach above object, the technical scheme that the utility model provides is: a kind of open type bidirectional flow filter plant, comprise the filter mechanism in cylindrical shell and cylindrical shell, the top of this cylindrical shell is worn-out open architecture, and this filter mechanism comprises the upper filtering layer and lower filtering layer that arrange from top to bottom; On this, filtering layer comprises the upper strata base plate be located in the middle part of this cylindrical shell, upper strata filter plate, bed course and upper filter material layer is set gradually from bottom to up above this upper strata base plate, the bottom of this upper strata filter plate arranges multiple upper strainer head, and this cylindrical shell between this upper strata filter plate and this upper strata base plate is provided with outlet pipe; This lower filtering layer comprises the lower floor's base plate being located at this cylinder body bottom, lower floor's filter plate, supporting layer, lower filter material layer is set gradually from bottom to up above this lower floor's base plate, the bottom of this lower floor's filter plate is provided with multiple lower strainer head, and this cylindrical shell between this upper strata filter plate and this lower filter material layer is provided with water hole, this cylindrical shell between this lower floor's filter plate and this lower floor's base plate is provided with inlet opening; This cylindrical shell outer upper arranges dirt discharge groove, and this water side crossing water square hole is communicated with this dirt discharge groove, and this dirt discharge groove groove rises out this cylindrical shell top, arranges blow-off pipe bottom this dirt discharge groove.
Being improved to further of such scheme, this cylindrical shell being positioned at this lower filtering layer arranges manhole, to facilitate the lower filtering layer of maintenance.
Being improved to further of such scheme, this dirt discharge groove groove rises out this cylindrical shell top 200cm.
Being improved to further of such scheme, this upper filter material layer is loose heap formula fiber filtering layer, and this lower filter material layer is quartz sand particle filter material layer.
Being improved to further of such scheme, this lower floor's base plate and this cylindrical shell are integrated.
Being improved to further of such scheme, around cylindrical shell in the form of a ring, and the bore of this dirt discharge groove lower end reduces and connects with this cylinder body outer wall this dirt discharge groove gradually.
The utility model is mainly used in urban water supply process, industrial water supply process, and the engineerings such as mark transformation are put forward by Treated sewage reusing process and sewage treatment plant.
Operation principle of the present utility model is: former water enters the utility model open type bidirectional flow filter plant from the inlet opening bottom lower filtering layer, supporting layer and lower filtering layer (quartz sand particle filter material layer) is entered by the strainer head be arranged on lower floor's filter plate, after quartz sand particle filtrate coarse filtration, upwards flow, enter dirt discharge groove through the water hole being arranged on lower filtering layer top; Water outlet in dirt discharge groove to cover after cylindrical shell by Action of Gravity Field, enters filtering layer, carries out secondary filter through upper filtering layer (loose heap formula fiber filtering layer), and after filter, water enters outlet pipe and discharges after long handle list filter, and like this, the effluent quality after secondary filter is better.During cleaning blowdown, the sewage in dirt discharge groove is discharged through blow-off pipe.
The beneficial effects of the utility model are: 1. rational in infrastructure, easy to operate, weight is little, with low cost, and its upper side is unlimited, and filtrate is easily entered.2. under equipment, filtering layer is quartz sand particle filter material layer, due to Action of Gravity Field, the filtrate of quartz sand particle filter material layer presents decrement states from bottom to up, when entering the upward flow filtration of lower filtering layer, filtrate in lower filtering layer successively decreases from big to small along the water (flow) direction of filtering, between filtrate, hole also successively decreases, and can hold more dirt, filtering layer coarse filtration of realizing ideal; On equipment, filtering layer is fiber filtering layer, and enter the lower to when flowing through filter of filtering layer, filtering layer is Uniform Slender filtrate, and filtering layer can retain less dirt, realizes secondary filter, ensures that effluent quality is good.3., during blowdown, the annular blowdown cone groove of setting can reduce the delay of dirt.4. the utility model filter plant is easy to make, carbon steel sheet can be adopted to be welded, also can build by laying bricks or stones with armored concrete, brick setting.
