Description

Water treatment facilities and hemodialysis system

Technical Field

The application relates to the technical field of water treatment, in particular to a water treatment device and a hemodialysis system.

Background

Hemodialysis is one of the kidney replacement treatment regimens used by patients with acute and chronic renal failure. In hemodialysis, the blood in the patient is drained to the outside of the body, purified by a dialyzer containing a large number of hollow fibers, and then returned to the patient. Through hemodialysis, the treatment aims of clearing metabolic waste and redundant water in vivo and maintaining electrolyte and acid-base balance can be fulfilled. In the dialyzer, blood flows in the hollow fibers, dialysate flows outside the hollow fibers in the opposite direction, and the blood and the dialysate exchange substances in modes of dispersion, ultrafiltration, adsorption, convection and the like, so that the aim of purifying the blood is fulfilled.

The dialysate is generally obtained by diluting a dialysate concentrate containing electrolytes and bases with pure water in a proportion, and the concentration of the electrolyte is close to that in normal blood. Since city tap water contains various trace elements, particularly heavy metals, and also contains disinfectants, endotoxins, bacteria and the like, water treatment equipment is required, but the water treatment effect of the water treatment equipment in the related art is not good enough, so that the hemodialysis effect of a hemodialysis system is affected.

Embodiments of the first aspect of the present application provide a water treatment apparatus, as shown in fig. 1, comprising a first water inlet conduit 110, a hydrogenation unit 20, a first reverse osmosis unit 30, a first water outlet conduit 120 and a first water return conduit 130. The hydrogenation device 20 comprises a first water inlet 201 and a first water outlet 202, one end of the first water inlet pipe 110 is communicated with the first water inlet 201, the other end is communicated with the water supply equipment 100, and the hydrogenation device 20 is used for increasing the hydrogen ion content in the water to be treated; the first reverse osmosis device 30 comprises a second water inlet 301, a third water inlet 303 and a second water outlet 302, the second water inlet 301 is communicated with the first water outlet 202, and the first reverse osmosis device 30 is used for performing reverse osmosis treatment on water to be treated; one end of the first water outlet pipeline 120 is communicated with the second water outlet 302, and the other end is communicated with the water using equipment 40; one end of the first return water pipe 130 is communicated with the water using device 40, and the other end is communicated with the third water inlet 303.

In the embodiment of the present application, as shown in fig. 1, the first water inlet pipe 110 communicates the water supply apparatus 100 with the first water inlet 201, and further communicates the water supply apparatus 100 with the hydrogenation apparatus 20, so that the water to be treated flows from the water supply apparatus 100 to the hydrogenation apparatus 20. The hydrogenation unit 20 is in communication with a first water inlet conduit 110 and a first reverse osmosis unit 30.

Further, the hydrogenation apparatus 20 may be an electrolytic water apparatus, and further, the hydrogenation apparatus 20 may include a first chamber, a second chamber, and a hydrogen permeable membrane disposed between the first chamber and the second chamber. First cavity and first water inlet 201 intercommunication can be provided with the brineelectrolysis spare in the first cavity, and the brineelectrolysis spare can be with the pending water electrolysis that gets into first cavity through first water inlet 201, forms hydrogen-soluble water in first cavity, and wherein hydrogen-soluble water is the higher water of hydrogen ion content, can improve the hydrogen ion content of the pending water in the first cavity from this. Then the water with higher hydrogen ion content in the first chamber is filtered through the hydrogen permeable membrane, and the water with higher hydrogen ion content is filtered from the first chamber to the second chamber. The hydrogen permeable membrane may be a hollow fiber membrane which is a porous membrane through which hydrogen molecules pass, and hydrogen ions dissolved in a liquid can be passed from a high-concentration fluid side to a low-concentration fluid side. The water having a high hydrogen ion content generated by the electrolytic water element is located in the first chamber, and therefore the water in the first chamber has a greater hydrogen-soluble concentration than the water in the second chamber. Therefore, the hydrogen permeable membrane moves the hydrogen ions dissolved in the liquid from the first chamber having a high dissolved hydrogen concentration to the second chamber having a low dissolved hydrogen concentration. The second chamber is communicated with the first water outlet 202, and the water with higher hydrogen ion content is sent to the second water inlet 301 through the first water outlet 202 and then enters the first reverse osmosis device 30. The hydrogen permeable membrane may be another polymer membrane that can allow hydrogen ions dissolved in a liquid to pass from a high-concentration fluid side to a low-concentration fluid side, and the present application is not limited thereto. Further, the hydrogenation apparatus 20 may have other configurations, which is not limited in the present application.

As shown in FIG. 1, the first reverse osmosis device 30 is connected with the hydrogenation device 20 and the water using device 40, and the first water outlet pipeline 120 is communicated with the first reverse osmosis device 30 and the water using device 40. The first reverse osmosis apparatus 30 can further filter water having a high hydrogen ion content to form dialysis water usable for human hemodialysis. The dialysis water is then supplied to the water consuming device 40 via the first water outlet line 120 for use. The water using device 40 may be a dialysis device such as a dialysis machine. The first return conduit 130 connects the water consuming device 40 and the first reverse osmosis apparatus 30, and the first reverse osmosis apparatus 30 and the water consuming device 40 form a closed circulation loop through the first outlet conduit 120 and the first return conduit 130. The unused dialysis water can flow into the first reverse osmosis device 30 again through the first return water pipe 130 and enter the next circulation supply water equipment 40 for use, so that the dialysis water which is not used by the water equipment 40 is recycled again, the waste of the dialysis water is reduced, the use cost of the water treatment equipment is reduced, and the use cost of the hemodialysis equipment is further reduced.

In the embodiment of the present application, as shown in fig. 1, the water to be treated flowing out from the water supply apparatus 100 enters the first water inlet 201 through the first water inlet pipe 110, and then enters the hydrogenation apparatus 20, and the hydrogenation apparatus 20 can improve the hydrogen ion content in the water to be treated through the modes of electrolyzing water and the like, so as to improve the water treatment effect of the water treatment apparatus and improve the hemodialysis effect. Then the water to be treated with high hydrogen ion content flows out from the first water outlet 202, flows into the first reverse osmosis device 30 through the second water inlet 301 communicated with the first water outlet 202, filters the water to be treated with high hydrogen ion content to form dialysis water after filtering, and the dialysis water flows out from the second water outlet 302, is sent to the water using equipment 40 through the first water outlet pipeline 120, and is supplied to the dialysis machine. The dialysis water that is not used in the water treatment apparatus 40 flows into the third water inlet 303 through the first water return line 130, and re-enters the first reverse osmosis device 30, and is further recycled to the water treatment apparatus 40, so that the pressure and flow rate of the dialysis water in the first water outlet line 120 and the first water return line 130 can be stabilized, and the stability of the water treatment apparatus can be improved. In the embodiment of the present application, the hydrogenation device 20 in the water treatment apparatus can increase the hydrogen ion content in the water treated by the water treatment apparatus, that is, increase the hydrogen ion content in the water for dialysis, thereby increasing the water treatment effect of the water treatment apparatus. The dialysis water with high hydrogen ion content can reduce oxidative stress and inflammatory reaction caused by using the dialysis water in human body, and improve hemodialysis effect. In addition, the dialysis water with high hydrogen content can reduce fatigue and pruritus caused by human body dialysis, reduce side effects such as hypertension caused by dialysis water, and further improve hemodialysis effect.

In some embodiments, as shown in fig. 1, the water treatment apparatus further includes a filtering device 10, the filtering device 10 is disposed on the first water inlet pipe 110, the filtering device 10 is located on a side of the hydrogenation device 20 away from the first reverse osmosis device 30, and the filtering device 10 is used for filtering water to be treated.

In the embodiment of the present application, the filtering apparatus 10 is disposed between the water supply apparatus 100 and the hydrogenation apparatus 20. The water to be treated flowing out of the water supply apparatus 100 has many impurities harmful to the human body, such as silt particles having a diameter of less than 500 μm, soluble organic matters, and magnesium, calcium, etc. The filtering device 10 can filter impurities in the water to be treated, and improve the water treatment effect of the water treatment equipment. In this case, the water to be treated is untreated raw water.

In some embodiments, as shown in fig. 1, the filter device 10 includes a sand tank 11, a carbon tank 12, and a resin tank 13, which are sequentially disposed in a flow direction of water to be treated in the first water inlet pipe 110.

In the embodiment of the present application, the sand tank 11 is used as a first stage filter of the filtering device 10, and can reduce the content of silt particles with a diameter smaller than 500 μm in raw water. The canister 12 is a second stage filter of the filtering apparatus 10, and the filtering material in the canister 12 may be activated carbon or other filtering material with strong adsorptivity, which is not limited in this application. The activated carbon has a microporous structure and a large surface area, and can adsorb impurities such as soluble organic matters, active chlorine and chloramine, pyrogen, pigments and the like in the water to be treated and reduce the content of the impurities such as the soluble organic matters, the active chlorine and the chloramine, the pyrogen, the pigments and the like in the water to be treated. The resin tank 13 is a third stage filter of the filtering device 10, and the filtering material in the resin tank 13 may be cationic resin, i.e. the surface of the resin is wrapped with sodium ions. The resin tank 13 can be used as an ion exchanger, and sodium ions coated on the surface of the resin can be exchanged with calcium ions, magnesium ions and the like in the water to be treated, so that the content of the calcium ions, the magnesium ions and the like in the water to be treated is reduced.

In the embodiment of the application, sand tank 11, carbon tank 12 and resin tank 13 can filter the diameter that the pending aquatic has and be less than impurity such as 500 mu m's silt particle, soluble organic matter, magnesium ion and calcium ion, improve water treatment facilities's water treatment, improve the hemodialysis effect.

In some embodiments, the first reverse osmosis device 30 further comprises a water storage tank located inside the first reverse osmosis device 30 and communicating with the first return water conduit 130 through the third water inlet 303.

In the embodiment of the present application, a water storage tank may be located inside the first reverse osmosis apparatus 30 for storing dialysis water that is not used by the water using device 40. The unused dialysis water flows through the first return water pipe 130, enters the third water inlet 303, further flows into the first reverse osmosis device 30, and enters the circulation loop supply water equipment 40 again for use, so that the use cost of the water treatment equipment can be reduced, and the use cost of the hemodialysis can be further reduced.

Further, the water storage tank may be located outside the first reverse osmosis device 30, and is communicated with the second water outlet 302 of the first reverse osmosis device 30 via a pipeline or the like, so as to realize water circulation.

In some embodiments, the first reverse osmosis device 30 further includes a concentrate chamber, a pure water chamber, and a reverse osmosis membrane disposed between the concentrate chamber and the pure water chamber, the second water inlet 301 is communicated with the concentrate chamber, and the second water outlet 302 is communicated with the pure water chamber.

In this embodiment, the concentrated water chamber is communicated with the second water inlet 301 for holding the water to be treated which is not treated by reverse osmosis, and the water to be treated enters the pure water chamber after being filtered by reverse osmosis membrane, and then flows into the second water outlet pipeline through the second water outlet 302, and then is supplied to the water consuming device 40. Wherein, the reverse osmosis membrane can be a semipermeable membrane. The reverse osmosis membrane can block soluble inorganic matters, organic matters, bacteria, endotoxin viruses and particles with the molecular weight of more than 300, and can reject 90-95% of bivalent ions and 95-99% of monovalent ions. The water having a high hydrogen ion content is separated into two parts by the reverse osmosis membrane after entering the first reverse osmosis device 30, and the water having a high hydrogen ion content passing through the reverse osmosis membrane is called reverse osmosis water (pure water) and is located in a pure water chamber. The other part of the water with higher hydrogen ion content which is not rejected by the reverse osmosis membrane is called reject water (concentrated water) and is positioned in a concentrated water chamber, and the concentrated water chamber contains 90-99% of inorganic substances and organic substances. The first reverse osmosis device 30 can reduce the content of impurities such as soluble inorganic substances, organic substances, bacteria and the like in water with high hydrogen ion content, improve the water treatment effect of the water treatment equipment, and improve the hemodialysis effect.

Further, the first reverse osmosis device 30 may further include a high pressure pump for applying pressure to the concentrate chamber such that the pressure of the concentrate chamber exceeds osmotic pressure of the reverse osmosis membrane. In general, the solvent moves from the low concentration solution side to the high concentration solution side, and the osmotic pressure is a force that urges the solvent in the low concentration solution to the high concentration solution side. The concentrated water chamber contains 90% -99% of inorganic matters and organic matters, so that the water concentration of the concentrated water chamber with higher hydrogen ion content is higher than that of the pure water chamber. The high pressure pump can move the water with high hydrogen ion content from the high concentration solution side to the low concentration solution side, i.e. the water with high hydrogen ion content enters the pure water chamber from the concentrated water chamber through the reverse osmosis membrane, and then forms the dialysis water for the water supply device 40.

The first reverse osmosis device 30 and the second reverse osmosis device 60 may be substantially the same in type and structure. The structure of the second reverse osmosis device 60 can be referred to the detailed description of the first reverse osmosis device 30, and the detailed description thereof is omitted.

Further, the first return water pipe 130 may be connected to the second reverse osmosis device 60, and the unused dialysis water in the water using device 40 may be introduced into the second reverse osmosis device 60, so that the unused dialysis water may be recycled to the next circulation for use by the water using device 40. Correspondingly, the second reverse osmosis device 60 may further include a water storage tank, the water storage tank is used for storing the unused dialysis water of the water consuming device 40, the water storage tank may be disposed inside the second reverse osmosis device 60, or disposed outside the second reverse osmosis device 60, and may be disposed according to actual requirements, which is not limited in this application.

Therefore, the pressure pump can ensure that the water treatment equipment has constant water supply pressure and water supply flow, can maintain the minimum water supply pressure and water supply flow necessary for the water treatment equipment, and can also improve the flow rate of water in the pipeline, thereby improving the water treatment efficiency of the water treatment equipment and improving the stability and the safety of the water treatment equipment.

Accordingly, the operation states of the first pressurizing pump 111 and the second pressurizing pump 121 may be determined according to the water supply pressure and the water supply flow rate in the first water inlet pipe 110 and the first water outlet pipe 120. The operation states of the first pressure pump 111 and the second pressure pump 121 include, but are not limited to, on, off, on time, off time, and the like of the first pressure pump 111 and the second pressure pump 121.
