The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model is further specified.
As shown in Figure 1; A kind of counter-infiltration system; Comprise the storage tank that connects successively through inlet channel 21, first valve 3, booster pump 4, check valve 5, second valve 6, high pressure protector 7, first Pressure gauge 8, reverse osmosis membrane assembly 9; Reverse osmosis membrane assembly 9 produce water outs through water producing pipe road 23 with the 4th valve 12, produce water tank 13 and be connected, reverse osmosis membrane assembly 9 dense water outs are connected with dense water circulating pipe 22 and concentrated water discharge pipeline 18, concentrated water discharge pipeline 18 is provided with the 7th valve 19; Dense water circulating pipe 22 is provided with the 8th valve 20 and flowmeter 21, and dense water circulating pipe 22 links to each other with booster pump 4 preceding inlet channels 2.In addition, also be provided with liquid flowing tube road 24 on the water producing pipe road 23, liquid flowing tube road 24 is provided with the 3rd valve 10, also is provided with second Pressure gauge 11 on the water producing pipe road 23; Also be connected with medicine on the reverse osmosis membrane assembly 9 dense water outs and wash a reflux line 15 and a flushing discharge tube 16, medicine is washed reflux line 15 and is provided with the 5th valve 14, and flushing discharge tube 16 is provided with the 6th valve 17.
During concrete the use; Water from storage tank 1 at first increases water flow pressure via booster pump 4, because hydrone will come out through reverse osmosis membrane separation, and pressure that must be certain; First valve 3, second valve 6 respectively are set in booster pump 4 front and back; When this setting is convenient to booster pump 4 and is broken down, can first valve 3, second valve 6 be shut, booster pump 4 is unloaded place under repair.A check valve 5 is set behind booster pump 4, and the adverse current phenomenon appears in anti-sealing.On the inlet channel 2 before current get into reverse osmosis membrane assembly 9, a high pressure protector 7 is set, when water flow pressure was excessive, high-voltage switch gear can cut off the power supply of pump automatically, plays the high voltage protective effect; First Pressure gauge 8, second Pressure gauge 11 also are set simultaneously, and immediate observation water inlet and produce the pressure of water if pressure is higher, then is that dirty stifled phenomenon has appearred in reverse osmosis membrane.
Product water multiparity waterpipe 23 after reverse-osmosis treated gets into and produces water tank 13 storages, and liquid flowing tube road 24 and the 3rd valve 10 are set on water producing pipe road 23, and as sampling usefulness, the 4th valve 12 is regulated aquifer yields; And the dense moisture that produces is four the tunnel to walk, and the utility model increases dense water circulating pipe 22 on the basis of traditional dense water lines of counter-infiltration system, increase the flux of water, prevents that dirty stifled phenomenon from appearring in film, with the stability and the rate of recovery of raising system.The concrete Fig. 1 that combines describes this four pipeline:
1) first via is that medicine is washed reflux line 15,15 controls of this route the 5th valve, and this valve also is to be in normally off, washes Shi Caihui and opens when this system carries out medicine;
2) the second tunnel is flushing discharge tube 16, is controlled by the 6th valve, and this valve normally is in normally off, when cleaning this counter-infiltration system, just can open;
3) Third Road is dense water circulating pipe 22, and by 20 control and regulation of the 8th valve, flowmeter 21 can be read dense water circular flow, and pipeline takes back to booster pump 4;
4) the four the tunnel is concentrated water discharge pipeline 18, by 19 control and regulation of the 7th valve, with concentrated water discharge.
The utility model increases by one road dense water circulation pipe on the discharge pipe of the dense water of counter-infiltration system, be circulated to booster water pump before, reduce concentrated water drainage high-volume; Improve utilization rate, the service life of film and the stability of system of water, have advantages such as simple in structure, control convenience; Circulating through dense water increases the water inlet of reverse osmosis membrane flux; Prevent that dirty stifled phenomenon from appearring in film, reduce the discharging of dense water, improve the stability and the rate of recovery of system.Its water saving principle such as Fig. 2, shown in Figure 3, the rate of recovery of supposing reverse osmosis membrane is 50%, aquifer yield is 0.5m
3/ h:
1) in the traditional no concentrate recirculation counter-infiltration system technology, aquifer yield will reach 0.5m3/h, and inflow need have 1m
3/ h, and concentrated water discharge 0.5m
3/ h, the system recoveries rate only has 50%;
2) this patent adopts in the counter-infiltration system of concentrate recirculation, and aquifer yield will reach 0.5m3/h, and inflow only need have 0.67m
3/ h, and dense water circulation 0.33m
3/ h, discharging 0.17m
3/ h, the system recoveries rate can reach 75%.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
