Whole water purification unit includes tertiary water treatment process, in leading active carbon filter core department, effectively get rid of the chlorine residue in aquatic, humus, disinfection accessory substance, stink, heterochrosis etc. during the water that passes through first grade filtering layer treatment entered into the PP filter core, the aperture is small, about a micron, get rid of iron rust, fine grit, later water enters into the reverse osmosis filter core, the membrane aperture that the reverse osmosis filter core used is minimum, adopt the membrane of commonly-used 0.5 ~ 1 nanometer, hold back bacterium, virus, heavy metal ion and organic matter molecule, water at user side exhaust is superior to the drinking water standard, reach and prepare the straight drinking water purpose.
Furthermore, the water purification equipment also comprises a water storage tank, the water storage tank is arranged on a branch of the pipeline between the reverse osmosis filter element and the user end, and a branch with a tail end used as a flushing discharge end is arranged between the water inlet end and the front active carbon filter element of the water pipeline. After adding the water storage tank, can stabilize the pressure stability of user side play rivers greatly, prevent that the user side water from leading to booster pump department supply untimely often play water pressure fluctuation too fast, exactly, leading activated carbon filter core, the PP filter core, reverse osmosis filter core live time is one long, can pile up impurity in filter position department, pull down and wash too troublesome, so, reserve some waters in water storage tank department, when needs wash three filter core, the water drainage in the water storage tank comes, reverse pass three filter core in proper order, outside the discharge end eduction gear of following washing, during rivers reverse flow, through taking place to cut off the water way pipe and intake the end be connected, prevent that the foul from flowing toward the water pipe.
Further, the water storage tank is a gas pressure stabilizing tank. The top in the water storage tank accumulates the gas of compression state, and the pressure of this part of gas both is the water pressure in the water storage tank, and gaseous steady voltage back can obtain more invariable water outlet pressure, two kilograms or three kilograms for example, this water outlet pressure no longer is restricted to the intake pressure fluctuation of intaking the end and the acting of booster pump unstable, also no longer receives the play water pressure change that the interior filtration principle of reverse osmosis filter core felt, and the user can dispose accurate play water pressure on the water storage tank according to self demand.
Further, the reverse osmosis filter core includes the membrane shell and sets up the two-layer semipermeable membrane in its inside, be three runners by two-layer semipermeable membrane separation in the membrane shell, be the first runner respectively, intermediate level runner and last stage runner, set up three interface respectively on the membrane shell wall, be the water inlet respectively, delivery port and waste liquid mouth, first runner one end is connected the water inlet, one end sets up the first discharge pipe and is connected to the waste liquid mouth, intermediate level runner one end is sealed, one end sets up the intermediate level discharge pipe and is connected to the waste liquid mouth, last stage runner one end is sealed, one end is connected to the delivery port, the intermediate level runner is located between first runner and the last stage runner, the water pipe that the booster pump was come is connected to the water inlet, the delivery port is even to the water storage tank, set up the first waste liquid valve on the first discharge. The booster pump pumps water into a first-stage flow passage, a pressure area can be formed in the first-stage flow passage by adjusting the opening degree of a first-stage waste liquid valve, a clean water body can penetrate through a semipermeable membrane between the first-stage flow passage and a middle-stage flow passage to enter the middle-stage flow passage as long as the pressure difference between the first-stage flow passage and the middle-stage flow passage is higher than the osmotic pressure of liquid in the two flow passages, the pressure in the middle-stage flow passage is higher than that in the last-stage flow passage, the water body can continuously enter the last-stage flow passage from the middle-stage flow passage, so that a pressure gradient is formed, the concentration gradient of reverse osmosis filtration is gradually reduced from the first-stage flow passage to the last-stage flow passage, compared with only one layer of semipermeable membrane, the double-layer semipermeable membrane can realize the integral larger pressure difference under the smaller single-stage pressure difference, for example, a single, the water body is firstly purified into the middle-stage flow passage, the concentration of the water body solute in the middle-stage flow passage is lower, the water body solute can easily penetrate through the semipermeable membrane to enter the final-stage flow passage, the concentration difference between the water in the first-stage flow passage and the water in the middle-stage flow passage is smaller, therefore, a larger proportion of the water body in the first-stage flow passage enters the middle-stage flow passage, the concentration of waste liquid discharged from a first-stage discharge pipe can be very high, the waste of water resources is inhibited, the higher pressure of the middle-stage flow passage relative to the final-stage flow passage is established through the water body coming from the first-stage flow passage, the pressure of the first-stage flow passage is increased to be higher than that of the final-stage flow passage after the first-stage flow passage enters the middle-stage flow passage, then the reverse osmosis process from the middle-stage flow passage to the final-stage flow passage is carried out, and it needs to be noted that the removal, when the water body is lifted to influence the reverse osmosis of the middle-stage runner to the final-stage runner, the middle-stage waste liquid valve needs to be opened to discharge a part of the water body in the middle-stage runner, and then the water body in the first-stage runner or the final-stage runner enters the middle-stage runner to be diluted.
Furthermore, a first differential pressure gauge is arranged between the primary flow channel and the middle flow channel, the primary waste liquid valve is an electromagnetic opening valve, and the primary waste liquid valve is electrically connected with the first differential pressure gauge. The first differential pressure gauge detects the pressure difference between the first-stage flow channel and the middle-stage flow channel, when the pressure difference is overlarge, the concentration is increased due to the fact that more solutes are accumulated in the first-stage flow channel, the osmotic pressure between the first-stage flow channel and the middle-stage flow channel is increased, and at the moment, in order to guarantee that the first-stage semipermeable membrane is not damaged, the first-stage waste liquid valve is required to be enlarged.
Furthermore, a second differential pressure gauge is arranged between the middle-stage runner and the final-stage runner, the middle-stage waste liquid valve is an electromagnetic opening valve, and the middle-stage waste liquid valve is electrically connected with the second differential pressure gauge. When the second differential pressure gauge detects that the differential pressure is larger, the concentration is increased due to more accumulated solutes in the middle-stage flow passage, and at the moment, part of water in the middle-stage flow passage needs to be discharged and enters purified water from two sides for dilution.
Furthermore, the aperture of the semi-permeable membrane between the middle-stage runner and the first-stage runner is smaller than that between the middle-stage runner and the last-stage runner. The pressure difference between the middle-stage runner and the first-stage runner is directly supplied by a booster pump, so the requirement of the pressure difference can be met, the average concentration of water bodies on two sides of the semi-permeable membrane is higher than that on two sides of the semi-permeable membrane on the second layer, the salt, bacteria and the like in a larger proportion can be quickly filtered away by using a higher concentration difference on the first stage, the pressure difference on two sides of the second-stage semi-permeable membrane is not directly provided by a pump, and only fluid pressure leaked from the first-stage runner can be used, so the aperture of the semi-permeable membrane on the second stage is larger, the maximum osmotic pressure value on two sides is lower, more proportions of purified water are allowed to be discharged from the middle-stage runner to the last-stage runner, the accumulation speed of the salt in the middle-stage runner is not high, and the whole number of times that the middle-stage runner needs to open a middle-stage waste liquid valve to discharge liquid, the desalting rate of the whole reverse osmosis filtering process is not reduced, and the waste liquid discharge frequency of the middle-stage flow passage is greatly reduced.
Compared with the prior art, the invention has the following beneficial effects: the invention is formed by a combined filter element, which respectively removes disinfection byproducts, organic matters, peculiar smell, heterochrosis, pipeline rust, fine sand stones, bacteria, most metal ions and other impurities of inlet water, so that the water body directly meets the drinking water standard; wherein be used for filtering the bacterium, the virus, among metal ion's the reverse osmosis filter core, use doublestage pellicle structure, the concentration of waste liquid has been improved greatly, thereby the waste that the waste liquid emission caused has been reduced, single booster pump supplies the pressure, need not extra energy structure, as the intermediate level runner of intermediate medium, the bacterium, the concentration of salinity promotes slowly, so, open the waste reduction that the intermediate level runner comes the flowing back, the aperture of doublestage pellicle is different, the primary is great and the secondary is less, when guaranteeing whole desalination rate, improve the waste liquid frequency of intermediate level runner, the setting of two differential gauges, let the intermediate level runner can purposeful allotment with the emission of primary runner, the control emission concentration proportion, thereby the life-span of two overall pellicle is unanimous.

The water storage tank 5 is a gas pressure stabilizing tank. The top in the water storage tank 5 accumulates the gas in a compressed state, the pressure of the gas is the water pressure in the water storage tank 5, after the gas is stabilized, a more constant water outlet pressure, for example, two kilograms or three kilograms, can be obtained at the user end 72, the water outlet pressure is no longer limited by the inflow pressure fluctuation of the inflow end 71 and the work instability of the booster pump 3, and the water outlet pressure change caused by the filtering principle in the reverse osmosis filter element 4 is no longer received, so that the user can configure the accurate water outlet pressure on the water storage tank 5 according to the self requirement.
The reverse osmosis filter element 4 comprises a membrane shell 41 and two layers of semipermeable membranes 45 arranged in the membrane shell 41, the membrane shell 41 is divided into three flow channels by the two layers of semipermeable membranes 45, the three flow channels are respectively a first-stage flow channel 411, a middle-stage flow channel 412 and a last-stage flow channel 413, three interfaces are respectively arranged on the wall surface of the membrane shell 41 and are respectively a water inlet 42, a water outlet 43 and a waste liquid port 44, one end of the first-stage flow channel 411 is connected with the water inlet 42, one end of the middle stage discharge pipe is provided with a first stage discharge pipe 441 and is connected to the waste liquid port 44, one end of the middle stage flow passage 412 is closed, one end of the middle stage discharge pipe 442 is provided and is connected to the waste liquid port 44, one end of the last stage flow passage 413 is closed, one end of the middle stage flow passage 412 is positioned between the first stage flow passage 411 and the last stage flow passage 413, the water inlet 42 is connected with the water pipeline 8 from the booster pump 3, the water outlet 43 is connected to the water storage tank 5, the first stage discharge pipe 441 is provided with a first stage waste liquid valve 443, and the middle stage discharge pipe 442 is provided. As shown in fig. 2 and 3, the booster pump 3 pumps water into the first-stage flow passage, a pressure area can be formed in the first-stage flow passage 411 by adjusting the opening degree of the first-stage waste liquid valve 443, a pressure difference between the first-stage flow passage 411 and the middle-stage flow passage 412 is higher than osmotic pressures of liquids in the two flow passages, so that clean water passes through the semipermeable membrane 45 between the first-stage flow passage 411 and the middle-stage flow passage 412 and enters the middle-stage flow passage 412, a pressure in the middle-stage flow passage 412 is higher than that in the last-stage flow passage 413, water continues entering the last-stage flow passage 413 from the middle-stage flow passage 412, a pressure gradient P0/P1/P2 is formed, a solute concentration gradient of reverse osmosis filtration is decreased from the first-stage flow passage 411 to the last-stage flow passage 413, compared with only one layer of semipermeable membrane, a double-layer of semipermeable membrane can realize an integral larger pressure difference under a single-stage pressure, the three-flow-channel structure of the double-layer semipermeable membrane can bear six atmospheric pressure differences, the water body is purified to the middle-stage flow channel 412 in advance, the concentration of the solute of the water body in the middle-stage flow channel 412 is low, the water body can easily penetrate through the semipermeable membrane to enter the final-stage flow channel 413, the concentration difference between the water body in the first-stage flow channel 411 and the water body in the middle-stage flow channel 412 is small, therefore, a large proportion of the water body in the first-stage flow channel 411 enters the middle-stage flow channel 412, the concentration of the waste liquid discharged from the first-stage discharge pipe 441 is high, waste of water resources is suppressed, the high pressure of the middle-stage flow channel 412 relative to the final-stage flow channel 413 is established through the water body from the first-stage flow channel 411, the first-stage flow channel 411 enters the middle-stage flow channel 412 and is boosted to a pressure higher than that of the final-stage flow channel 413, and then the process from the middle-stage flow channel 412 to the, still, some ions can pass through the semi-permeable membrane, so the solute concentration of the water in the intermediate flow channel 412 will rise slowly, and when the solute concentration rises to affect the reverse osmosis from the intermediate flow channel 412 to the final flow channel 413, the intermediate waste liquid valve 444 needs to be opened to discharge a part of the water in the intermediate flow channel 412, and then the water in the first or final flow channel enters the intermediate flow channel 412 for dilution treatment.
A first differential pressure gauge 461 is arranged between the first-stage flow passage 411 and the middle-stage flow passage 412, the first-stage waste liquid valve 443 is an electromagnetic opening valve, and the first-stage waste liquid valve 443 is electrically connected with the first differential pressure gauge 461. As shown in fig. 4, the first differential pressure gauge 461 detects the pressure difference between the first flow channel 411 and the middle flow channel 412, when the pressure difference is too large, which indicates that more solute is accumulated in the first flow channel 411 and the concentration is increased, the osmotic pressure between the first flow channel and the middle flow channel is increased, and at this time, the first waste liquid valve 443 should be adjusted to ensure that the first semi-permeable membrane 45 is not damaged.
A second differential pressure gauge 462 is disposed between the intermediate stage flow passage 412 and the final stage flow passage 413, the intermediate stage waste liquid valve 444 is an electromagnetic opening valve, and the intermediate stage waste liquid valve 444 is electrically connected to the second differential pressure gauge 462. When the second differential pressure gauge 462 detects a larger differential pressure, it indicates that more solute is accumulated in the middle stage flow passage 412 and the concentration is increased, and at this time, it is necessary to discharge part of the water in the middle stage flow passage 412 and enter the clean water from both sides for dilution.
The pore diameter of the semipermeable membrane 45 between the intermediate flow passage 412 and the first flow passage 411 is smaller than the pore diameter of the semipermeable membrane 45 between the intermediate flow passage 412 and the last flow passage 413. Specifically, the aperture of the semipermeable membrane 45 between the intermediate flow channel 412 and the first flow channel 411 may be about 0.5 nm, the aperture of the semipermeable membrane 45 between the intermediate flow channel 412 and the last flow channel 413 may be about 0.7 nm, and the pressure difference between the intermediate flow channel 412 and the first flow channel 411 is directly supplied by the booster pump 3, so that the requirement of the pressure difference can be satisfied, and the average concentration of the water body at the two sides of the semipermeable membrane is higher than that at the two sides of the semipermeable membrane of the second layer, the first layer uses the higher concentration difference to rapidly filter out a larger proportion of salt, bacteria and the like, the pressure difference at the two sides of the second semipermeable membrane is not directly supplied by the pump, only the fluid pressure leaked from the first flow channel 411 can be used, so that the aperture of the semipermeable membrane of the second layer is larger, the maximum osmotic pressure at the two sides is lower, a larger proportion of purified water is allowed to be discharged from the intermediate flow channel 412 to the last flow channel, and the accumulation, because the aperture of the first-stage semipermeable membrane is small, the desalination rate is high, so, on the whole, the number of times that the middle-stage waste liquid valve 444 needs to be opened for liquid drainage in the middle-stage flow channel 412 is not large, compared with the condition that the apertures of the two layers of semipermeable membranes are equal, the desalination rate of the whole reverse osmosis filtration process is not reduced, and the waste liquid drainage frequency of the middle-stage flow channel 412 is greatly reduced.
The rear active carbon filter element 6 can be additionally arranged in front of the user end 72 to improve the taste of the discharged water and ensure that the water stored in the water storage tank 5 can be in a fresh state when being discharged.
