Abstract
The utility model relates to a reversed return water outlet membrane component, belonging to the field of water treatment technologies. A water collection main pipe is connected with a plurality of water collection branch pipes which are uniformly distributed and mutually converged, and the plurality of water collection branch pipes are respectively connected with a plurality of groups of membrane components. The reversed return water outlet membrane component disclosed by the utility model has the advantages that the water outlet of all the membrane components realizes the reversed return to a water pump, the operation working conditions of all the membrane components are consistent, and the management and the maintenance are convenient; each membrane component has the same friction loss and partial loss so as to be favorable for prolonging the service life of membranes and reducing replacement; the placement of the membrane components is more centralized, and the arrangement shape can be regulated according to water treatment ponds in different shapes, so that the floor area is reduced; and compared with a direct return water outlet system, the reversed return water collection way can further shorten a water outlet pipeline for laying, and the cost can be also reduced.
Description
Technical field
The utility model belongs to water treatment field, particularly a kind of reversed return type water outlet membrane module.
Background technology
Along with the extensive utilization of membrane technique, process the increase of the water yield, the maximization of film processing system, integrated raising, adopt membrane technique more and more in whole water treatment field.And in membrane bioreactor the cost of the film height of comparing with other original paper, so how extend work-ing life of film, just become a key issue.The rising pipe of existing membrane module all is pooled in header, forms the form that series connection is catchmented, and aspirates away by producing water pump (being generally vacuum primingpump) at last, and this has just caused each membrane module is different apart from what produce water pump along journey.At the water outlet side that produces water pump, flow sensor is set, by the variable frequency control flow, the flow of using water pump is certain, carries out constant flow and filters.Due to the difference of linear loss, the water flow that causes membrane module is different, and along with the increase of distance, flow is more and more less.Therefore, because greatly easily causing dirt, filtration flux blocks up phenomenon near the membrane module that produces water pump, and minimum apart from the flux that produces water pump membrane module farthest, so two groups of films just are in different operating modes.And near produce the nearest membrane module of water pump dirty stifled after, the stifled speed of the dirt of the membrane module of back will be aggravated gradually thereupon, slows down the work-ing life of film, and causes medicine to wash the difference that time or film are changed, and is not easy to carry out integral body control.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, a kind of reversed return type water outlet membrane module is provided, it is a kind of new water outlet header design, make DRS formula outlet pipeline become reversed return type, the detrimentally affect that so just can avoid DRS to bring, every group of membrane module can be moved with identical mistake circulation, and operation condition is consistent.
The purpose of this utility model is achieved through the following technical solutions: a kind of reversed return type water outlet membrane module, it is characterized in that: it comprises many group membrane module, water header and the branched arms that catchment, said water header is connected with the branched arm that catchments that evenly distributes and mutually collect, and the branched arm that catchments is connected with many groups membrane module respectively.
A kind of reversed return type water outlet membrane module, it is characterized in that: it comprises many group membrane modules, water header, branched arm and the branched take-off pipe that catchments of catchmenting, said water header is connected with the branched arm that catchments that evenly distributes and mutually collect, the branched arm that catchments is connected with even distribution and the branched take-off pipe that catchments that mutually collects respectively, and the branched take-off pipe that catchments is connected with many groups membrane module respectively.
Advantage of the present utility model and beneficial effect are:
1, all with journey, the operation condition of each membrane module is consistent, conveniently administers and maintains to the distance of water pump in the water outlet of all membrane modules;
2, the linear loss of each membrane module and local losses are identical, are more conducive to extend the work-ing life of film, reduce and change;
3, membrane module is put more concentratedly, can regulate spread geometry according to difform water treating pond, thereby reduce floor space;
4, than the outlet system of DRS formula, the rainwater catchment of reversed return type shortens the laying of outlet pipeline more, can reduce cost.
Description of drawings
Fig. 1 is embodiment one structural representation of the present utility model.
Fig. 2 is embodiment two structural representations of the present utility model.
Wherein: the 1-arm that catchments, the 2-water header, the 3-membrane module, 4-goes out water pump, 5-membrane bioreactor, the 6-take-off pipe that catchments.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, embodiment, structure, the feature that the foundation utility model is provided and attack effect is described in further detail;
Embodiment one: as shown in Figure 1, a kind of reversed return type water outlet membrane module, membrane module is arranged in a round membrane bioreactor 5, and water header 2 is connected with 7 arms 1 that catchment that evenly distribute and mutually collect, and 7 arms 1 that catchment are connected with 7 groups of membrane modules 3 respectively.
Embodiment two: as shown in Figure 2, a kind of reversed return type water outlet membrane module, 8 groups of membrane modules 3 are arranged in square membrane bioreactor 5, water header 2 is connected with 4 arms 1 that catchment that evenly distribute and mutually collect, 4 arms 1 that catchment are connected with 2 take-off pipes 6 that catchment that evenly distribute and mutually collect respectively, and every support moisture arm 6 is connected with membrane module 3 respectively.
After water leaches from membrane module, by going out water pump 4, water is extracted out after focusing on house steward by arm, and by flow sensor variable frequency control flow, the water outlet of all membrane modules to the distance of water pump all with journey, the operation condition of each membrane module is consistent, linear loss is identical with local losses, is more conducive to extend the work-ing life of film, reduces and changes; Membrane module is put more concentrated, can regulate spread geometry according to difform water treating pond, thereby reduce floor space; Shorten the laying of outlet pipeline, can reduce cost.
The above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
