Abstract
A water-saving ultrafiltration device comprises an ultrafiltration pump and an ultrafiltration component, which are connected according to the pipeline sequence. The utility model is characterized in that a concentrated water return pipe is introduced from a concentrated water drainage pipe on the ultrafiltration component and returned to a water inlet pipe in front of the ultrafiltration pump; and the concentrated water return pipe is provided with a control valve for regulating the flow of the reflux concentrated water. The ultrafiltration device in the utility model changes from the original complete drainage of the concentrated water to partial drainage and partial reflux and reutilization, so as to effectively improve raw water utilization ratio and save precious water resource.
Description
Technical field
The utility model relates to a kind of filter that purifies water with milipore filter.
Background technology
Ultrafiltration apparatus is as a kind of filter, because it is wide to the influent quality requirement, product water water quality is good, thereby makes it be used widely in each filtration art.But in its application process, when milipore filter adopted the mode of cross-flow filtration, ultrafiltration apparatus produced a certain amount of dense water in application process at present; And in the present ultrafiltration apparatus, to this part dense water, all be not utilized and directly discharged, cause the ultrafiltration apparatus water use efficiency lower.And be becoming tight water resource day at present, thereby should only may improve the water use efficiency of ultrafiltration apparatus.
Summary of the invention
The purpose of this utility model mainly is the lower situation of water use efficiency that exists at existing ultrafiltration apparatus, carries out technological improvement, to improve the water use efficiency of ultrafiltration apparatus, the water resource of saves valuable.
Technical solution of the present utility model is: in the ultrafiltration apparatus that the ultrafiltrate pump that is linked in sequence with pipeline, milipore filter are formed, especially from ultrafiltration apparatus concentrated water discharge pipe, draw and pick out a concentrate recirculation pipe to ultrafiltrate pump, this concentrate recirculation pipe is provided with control valve, is used to regulate the concentrate recirculation amount.
In the utility model, the dense water with ultrafiltration apparatus produces in running is all discharged by original, change partial discharge and partial reflux utilization into, guaranteeing that ultrafiltration apparatus produces under the water water quality prerequisite, has effectively improved the water use efficiency of ultrafiltration apparatus, thereby has saved great amount of water resources.
Description of drawings
Accompanying drawing is the utility model general structure schematic diagram.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
As accompanying drawing, the first processing water that obtains from first treatment system is as former water 1, it sends into ultrafiltrate pump 3 through pipeline 2, after ultrafiltrate pump 3 pressurizations, by ultrafiltrate pump outlet 4, deliver to hyperfiltration membrane assembly 5, water inlet is after hyperfiltration membrane assembly 5 is handled, and the filtered water of output is delivered to outer net and become outer for filtered water 7 by pipeline 6, the dense water of ultrafiltration module output is disposed to dense pond 9 by delivery pipe 8.The utility model draws and picks out a concentrate recirculation pipe 10 especially before the control valve of the concentrated water discharge pipe 8 of ultrafiltration apparatus, on the former water water inlet pipe 2 before making it be connected to ultrafiltrate pump 3, and on concentrate recirculation pipe 10 control valve is set, and is used to regulate the concentrate recirculation amount.
Following table is that the utility model and common ultrafiltration apparatus production performance compare.
By above table as seen, under the situation of identical working condition and the qualified filtered water of output (requiring to produce water SDI index≤2), the more common ultrafiltration apparatus water saving 5% of the utility model.
