Fig. 3 is that the structure of the water-purifying machine of the dense water waste of minimizing that a kind of high water yield washes away membrane cartridge analyses and observe diagram:
(1), virgin state: all terminal valves are all in closure state.
(2) process of water purification, is manufactured:,
Source water enters into connecting passage 1A (1A), 0 grade or 1 grade from water-in (1) or is greater than 1 grade of preposition or mid-filter core (2), connecting passage 2A (2A), enter into RO film or nanofiltration membrane or ultrafiltration membrane filter element (3) to filter, water purification after filtration enters into 0 grade or 1 grade from pure water inlet connecting passage 3A1 (3A1) or is greater than 1 grade of rearmounted filter core (31) and filters further, last water purification is through connecting passage 3A2 (3A2), flow out from clear water faucet (4), Here it is manufactures the complete procedure of water purification.
(3), dense water flows out the process of avoiding wasting from water tap (11):
Play blowdown effect reduce TDS value reduce concentration polarization effect dense water be that sewer outlet connecting passage 6A (6A) that RO film or nanofiltration membrane or ultrafiltration membrane filter element (3) are communicated with enters into water tap (7) outflow, avoid traditional concentrated water discharge waste or in the extreme difficultly by the drawback of the water receivings such as washbowl, dense water can water tap (7) realize wash avoid dense water to waste target.
(4), dense water flows out the process of avoiding wasting from water tap (11):
Source water enters into connecting passage 1A (1A) from water-in (1), 0 grade or 1 grade or be greater than 1 grade of preposition or mid-filter core (2), connecting passage 2A (2A), filter through RO film or nanofiltration membrane or ultrafiltration membrane filter element (3), dense water is from sewer outlet connecting passage 6A (6A), and flow out from water tap (7), when opening water tap (7) at ordinary times, tap water clear water is with higher flow velocity flush clean RO film or nanofiltration membrane or ultrafiltration membrane filter element (3), reason due to the pumps design had causes the phenomenon of the flows decrease of tap water after water pump, slow down for preventing flow velocity the flush clean effect affected reverse osmosis membrane or nanofiltration membrane, can adopt and be communicated with tap water pipe line respectively with after pump before pump, ensure when opening water tap, the enough large thus flush clean strengthened reverse osmosis membrane or nanofiltration membrane etc. of flow velocity, see the position in Fig. 4 in detail, also can be according to actual needs, 0 or at least 1 waste water ratio or blowoff electromagnetic valve or manual valve or flow-limiting valve or pipe (10) all or part of outflow or cancel is not flowed out, facilitate water receiving due to water tap (7) water and hold, when opening clear water faucet (4), water tap (7) can be opened simultaneously, realize existing water purification or pure water, the effect of wasting dense water can be avoided again, if net water flux is large, also water tap (7) can not simultaneously be opened, dense water water-quality ratio tap water generally wants clean, may be used for washing one's hands, wash dish, wash the dishes, or connect and be put into washbowl etc. for other washing purposes, due to tap water open time, maximum amount of water or comparatively big yield can be reached, play the effect of better washing away membrane cartridge, simultaneously, when 0 above grade or 1 grade or be greater than 1 grade of preposition or mid-filter core (2) and such as adopt calcium sulfite filter core, then water tap (7) water chlorine residue out also can major part be removed.
Fig. 4 is the schema that water-in adopts when underfed:
Reason due to the pumps design had causes the phenomenon of the flows decrease of tap water after water pump, slow down for preventing flow velocity the flush clean effect affected reverse osmosis membrane or nanofiltration membrane, can adopt before pump be communicated with by-pass channel and connecting passage 1A1 (1A1) after pump respectively, namely water inlet can walk around 0 from connecting passage 1A (1A) or at least 1 pump 91 (91) directly enters into next pipeline or filter core, thus increase the flow of tap water, play the effect of the pollutent of the former water cavity deposition of flush clean RO film or nanofiltration membrane or ultrafiltration membrane filter element (3), thus play the life-span double utility saved dense water and extend filter core.
