Description of drawings
Accompanying drawing is used for understanding the utility model better, does not constitute improper restriction of the present utility model.Wherein:
Fig. 1 is the schematic diagram according to the basic structure of a kind of counter-infiltration water cleaning systems of the prior art;
Fig. 2 is the schematic diagram according to a kind of basic structure of the counter-infiltration water cleaning systems of the utility model embodiment;
Fig. 3 is the schematic diagram according to the another kind of basic structure of the counter-infiltration water cleaning systems of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing one exemplary embodiment of the present utility model is explained, to help understanding, they should be thought it only is exemplary comprising the various details of the utility model embodiment.Therefore, those of ordinary skills will be appreciated that, can make various changes and modification to the embodiments described herein, and can not deviate from scope and spirit of the present utility model.Equally, for clarity and conciseness, omitted the description to known function and structure in the following description.
Fig. 2 is the schematic diagram according to a kind of basic structure of the counter-infiltration water cleaning systems of the utility model embodiment.As shown in Figure 2, improvement has been done on the basis of the counter-infiltration water cleaning systems of the counter-infiltration water cleaning systems of the utility model embodiment in Fig. 1, except reverse-osmosis membrane element 11, inlet pipeline 12, wastewater effluent pipeline 13 and pure water outlet pipeline 14, also have a branch road 15, be connected between the entering water electromagnetic valve 121 and water pump 122 in the inlet pipeline 12.An air inlet magnetic valve 151 and an air pump 152 are arranged in this branch road.
This counter-infiltration water cleaning systems shown in Figure 2 is when bringing into operation, supposing does not have water in the current reverse-osmosis membrane element, close air pump 152 and air inlet magnetic valve 151 this moment, thereby opening scouring electromagnetic valve 132(makes wastewater effluent pipeline 13 be in unobstructed state), start water pump 122, former like this water (normally running water can carry out some preliminary treatment to running water and for example filter) just can enter reverse-osmosis membrane element 11 via entering water electromagnetic valve 121.Through the default time, for example behind the 8-15S, close scouring electromagnetic valve 132, make waste water waste water flowing proportional controller 131, wastewater effluent pipeline 13 is in waste water proportion control state like this, and this moment, counter-infiltration system shown in Figure 1 just began to produce pure water.
After the pure water of producing; shut down if desired; then stop water pump 122; close entering water electromagnetic valve 121; open air inlet magnetic valve 151; and scouring electromagnetic valve 132 is opened, thus booster air pump 152 in reverse-osmosis membrane element, inflate, the former water of its inside and gas that condensed water is all charged into are replaced.After replacement is finished; stop air pump 152; close air inlet magnetic valve 151; be air in the reverse-osmosis membrane element 11 like this; avoided in the prior art when the counter-infiltration water cleaning systems is shut down in the reverse-osmosis membrane element 11 because thereby two-way penetration has increased TDS, TDS is lower when so just having guaranteed in the early stage pure water processed.The gas that charges into can be air, also can be other safe gases.
Fig. 3 is the schematic diagram according to the another kind of basic structure of the counter-infiltration water cleaning systems of the utility model embodiment.The structure of counter-infiltration water cleaning systems shown in Figure 3 is to shown in Figure 1 similar, and difference is the water pump 122 among Fig. 2 is replaced with water and gas dual-purpose pump 123 among Fig. 3, and namely this pump 123 can pump water, also can pump gas.
The method of operation of the method for operation of counter-infiltration water cleaning systems shown in Figure 3 and counter-infiltration water cleaning systems shown in Figure 2 is similar, all be after producing pure water in the reverse-osmosis membrane element fill gas style such as air.Particularly, after counter-infiltration water cleaning systems shown in Figure 2 is produced pure water, open air inlet magnetic valve 151, close entering water electromagnetic valve 121, make wastewater effluent pipeline 13 be in unobstructed state, keep pump 123 to be in running status, thereby inflation is replaced the former water of its inside and gas that condensed water is charged in the reverse-osmosis membrane element 11.Close air inlet magnetic valve 151 after inflation, close scouring electromagnetic valve 132, counter-infiltration this moment water cleaning systems is in stopped status.
When needs are produced pure water, open entering water electromagnetic valve 121, close air inlet magnetic valve 151, make wastewater effluent pipeline 13 be in unobstructed state thereby open scouring electromagnetic valve 132, keep pump 123 to be in running status, thereby make water enter reverse-osmosis membrane element 11 via entering water electromagnetic valve 121; Next close scouring electromagnetic valve 132 after the time that process is preset, thereby make waste water waste water flowing proportional controller 131 make wastewater effluent pipeline 13 be in waste water proportion control state, like this, the counter-infiltration water cleaning systems begins to produce pure water.
From above description as can be seen; among the utility model embodiment; under the situation that counter-infiltration water cleaning systems production pure water is shut down then; the water inlet of the reverse-osmosis membrane element this counter-infiltration water cleaning systems of the Zhi Luxiang that connects between entering water electromagnetic valve and water pump charges into gas; the gas that the interior former water of this reverse-osmosis membrane element and condensed water are charged into is replaced; two-way penetration in the time of can avoiding shutting down like this in the reverse osmosis membrane, thus when making start operation again the initial stage during pure water processed TDS lower.This method is not only applicable to the counter-infiltration water cleaning systems of two kinds of structures in the present embodiment, and is suitable equally for the counter-infiltration water cleaning systems of other structures.
The above-mentioned specific embodiment does not constitute the restriction to the utility model protection domain.Those skilled in the art should be understood that, depend on designing requirement and other factors, and various modifications, combination, sub-portfolio and alternative can take place.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the utility model protection domain.
