Abstract
The utility model discloses a reverse osmosis treatment structure for high-hardness brackish water. The reverse osmosis treatment structure comprises a membrane element, wherein the water inlet end of the membrane element is connected with a pure water replacement inlet pipeline through an acid and alkaline resistant membrane metering pump; a hydrochloric acid feeding device is connected with the pure water replacement inlet pipeline; a test opening in the bottom of the membrane element is connected with a water storage device through a valve; an on-line PH meter capable of setting an upper limit and a lower limit and outputting a passive signal is arranged on a pipeline between the valve and the water storage device. In case of treatment, the high-flow flushing time is prolonged through the acid and alkaline resistant membrane metering pump; the hydrochloric acid feeding device feeds hydrochloric acid for cleaning and peeling a trace scale layer of the membrane element in time, and the valve is opened; and if the on-line pH meter measures that the pH value of discharged water is close to that of raw water, a quick flushing device and the hydrochloric acid feeding device are switched off, and normal running is recovered. The reverse osmosis treatment structure disclosed by the utility model guarantees the yield and the desalinization ratio of the membrane element, and the service life of the reverse osmosis treatment structure is prolonged.
Description
Technical field
The utility model relates to high rigidity brackish water reverse osmosis technology field, is specifically related to a kind of high rigidity brackish water reverse-osmosis treated structure.
Background technology
At present, in high rigidity brackish water reverse-osmosis treated process, the preventive measures that the easy fouling of membrane element is stopped up, generally adopt: add Scale inhibitors 1.; 2. be interrupted and carry out high flux flushing; 3. shut down and implement pure water displacement cleaning; still there is in actual applications membrane element surface scale latch up phenomenon in these three kinds of methods; because above measure still can cause micro-fouling, along with dirt layer Rapid Accumulation finally can cause shutting down the performance that matting can be recovered membrane element.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of high rigidity brackish water reverse-osmosis treated structure, guarantees output and the ratio of desalinization of membrane element, prolongs life.
In order to reach Shanghai Soviet Union object, the technical scheme that the utility model is taked is:
A kind of high rigidity brackish water reverse-osmosis treated structure, comprise membrane element 1, the feed-water end of membrane element 1 is connected with displacement pure water entrance pipe by acid and alkali-resistance METERING DIAPHRAGM PUMPS 2, hydrochloric acid adding device 3 is connected with displacement pure water entrance pipe, the bottom test port of membrane element 1 is connected with water reservoir 5 by valve 4, is provided with the PH in-line meter 6 that can set bound and output passive signal on the pipeline between valve 4 and water reservoir 5.
The utility model can guarantee below saltiness 4000ppm, and the brackish water of total hardness 3000ppm, when adopting reverse osmosis membrane desalination operation, reduces membrane element surface scale, guarantees output and the ratio of desalinization of membrane element, prolongs life.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to accompanying drawing, a kind of high rigidity brackish water reverse-osmosis treated structure, comprise membrane element 1, the feed-water end of membrane element 1 is connected with displacement pure water entrance pipe by acid and alkali-resistance METERING DIAPHRAGM PUMPS 2, hydrochloric acid adding device 3 is connected with displacement pure water entrance pipe, the bottom test port of membrane element 1 is connected with water reservoir 5 by valve 4, is provided with the PH in-line meter 6 that can set bound and output passive signal on the pipeline between valve 4 and water reservoir 5.
Principle of work of the present utility model is:
In the time of need to processing, first by acid and alkali-resistance METERING DIAPHRAGM PUMPS 2, increase the high flux flushing time, then by hydrochloric acid adding device 3, add hydrochloric acid to the timely clean stripping of membrane element 1 trace dirt layer, open valve 4, by PH in-line meter 6, survey and rinse when going out water ph value and former water ph value and approach, close Rapid washing device and hydrochloric acid adding device 3, recover normally operation.
