[0046] Figure 1 The flow chart of the modular hospital pure water supply system provided by the embodiments of this application is as Figure 1As shown in the figure, the present application provides a modular hospital pure water supply system. The supply system includes a raw water tank 110, a pretreatment module 100, a first-stage reverse osmosis module 200, and a first-stage pure water distribution station 220. The raw water tank 110 is used to provide raw water. The pretreatment module 100 is composed of a plurality of pretreatment skids 120 assembled by skid-mounted combination; the inlets of the plurality of pretreatment skids 120 are all connected to the raw water tank 110, and the outlets of the plurality of pretreatment skids 120 are all connected to the softened water tank 130; the pretreatment skid 120 is used to filter and convert the raw water into softened water and input the softened water into the softened water tank 130. The first-stage reverse osmosis module 200 is composed of a plurality of first-stage reverse osmosis skids 210 assembled by skid-mounted combination; the inlets of the plurality of first-stage reverse osmosis skids 210 are all connected to the softened water tank 130; the first-stage reverse osmosis skid 210 is used to filter and convert the softened water into first-stage pure water. The outlets of the plurality of first-stage reverse osmosis skids 210 are all connected to the first-stage pure water distribution station 220, and the first-stage pure water distribution station 220 is used to output the first-stage pure water externally.
[0047] In the modular hospital pure water supply system provided by the embodiment of the present utility model, the pretreatment module 100 is composed of a plurality of pretreatment skids 120 assembled by skid-mounted combination to filter the raw water, so that the raw water is converted into softened water. The first-stage reverse osmosis module 200 is composed of a plurality of first-stage reverse osmosis skids 210 assembled by skid-mounted combination to filter the softened water, so that the softened water is converted into first-stage pure water for medical use. Compared with building the water supply system in the form of existing engineering projects, in the present application, the water supply system is built by skid-mounted combination of the pretreatment skids 120 and the first-stage reverse osmosis skids 210. There is no need to install equipment such as valves and instruments, and only one skid base is required to complete the overall hoisting, with less on-site workload; the error caused by on-site construction is greatly reduced; the water supply quality is ensured by factory production of each functional module; the number of each module can be flexibly adjusted according to the water consumption level to reduce the use cost; each module with the same function is used as a backup for each other, which is convenient for maintenance and replacement; it runs stably and occupies less space.
[0048] In some embodiments, as Figure 1 shown, the softened water tank 130 is connected to the softened water supply device 140, and the softened water supply device 140 is used to output softened water externally. When each department of the hospital needs to use softened water, the softened water is obtained through the softened water supply device 140 for medical use.
[0049] Figure 2 For Figure 1 the connection schematic diagram of the first-stage reverse osmosis module in Figure 2As shown, in some embodiments, the primary reverse osmosis skid 210 includes a primary high-pressure pump 211 and a primary reverse osmosis membrane module 212. The primary high-pressure pump 211 and the primary reverse osmosis membrane module 212 are connected in sequence. The water inlet of the primary high-pressure pump 211 is connected to the softened water tank 130, the water outlet of the primary reverse osmosis membrane module 212 is connected to the primary pure water distribution station 220, and the water outlet of the primary reverse osmosis membrane module is also connected to the primary pure water tank 310. The primary high-pressure pump transports the softened water in the softened water tank 130 to the primary reverse osmosis membrane module. The primary reverse osmosis membrane module performs primary reverse osmosis filtration on the softened water to obtain primary pure water and transports the primary pure water to the primary pure water distribution station 220 for use by each department in the hospital.
[0050] In some embodiments, the primary reverse osmosis skid 210 includes a primary high-pressure pump, a primary reverse osmosis membrane module, a valve group, and on-line monitoring equipment for flow rate, pressure, and conductivity, as well as a stainless steel integrated rack. The primary reverse osmosis skid 210 is supplied as a complete set with an automatic control system. Primary pure water is a kind of high-purity water processed by reverse osmosis technology. Reverse osmosis technology is a technology that utilizes the selective permeability of a semi-permeable membrane. A pressure greater than the natural osmotic pressure is applied on one side of the membrane, causing the solvent water molecules to perform reverse osmosis against the direction of natural osmosis, thereby intercepting impurities such as ions, organic substances, bacteria, and viruses in the water to achieve the purpose of separation and purification. The driving force for this phenomenon comes from the pressure difference between the feed water (concentrate water) pressure and the osmotic pressure (which varies with the type and form of the reverse osmosis membrane).
[0051] In some embodiments, a globe valve is provided at the inlet of the primary reverse osmosis skid 210 to adjust the total water inlet volume to the designed water volume. The product water flow rate and the concentrate water pressure are adjusted by a pressure regulating needle valve installed on the concentrate water pipeline. When the primary pure water production volume is lower than the designed value, it indicates that the feed water (concentrate water) pressure is too small and the pressure difference is too small. The pressure regulating needle valve should be closed to increase the concentrate water (inlet water) pressure until the primary pure water production volume is equal to the designed value. Before starting the primary reverse osmosis membrane module, open the primary high-pressure pump and the total inlet valve, control the total inlet water pressure of the device < 0.5 MPa and flush for 5 minutes, and check whether the high- and low-pressure pipelines and instruments are normal. Adjust the inlet valve and the concentrate water discharge valve to make the inlet water pressure reach 1.0 - 1.4 MPa.
[0052] In some embodiments, such as Figure 1As shown, the primary pure water distribution station 220 is composed of a plurality of primary pure water distribution skids 221 assembled by skid-mounted units; each primary pure water distribution skid 221 includes a primary pure water tank 222, a primary pipeline 223, and a plurality of primary pure water supply devices 224. The outlets of a plurality of primary reverse osmosis skids 210 are all connected to the primary pure water tank 222. The outlet and the inlet of the primary pipeline 223 are both connected to the primary pure water tank 222. A plurality of primary pure water supply devices 224 are all arranged on the primary pipeline 223, and the primary pure water supply devices 224 are used to output the primary pure water circulating inside the primary pipeline 223 to the outside. The primary pure water obtained by primary reverse osmosis filtration enters the primary pure water tank 222. Since the outlet and the inlet of the primary pipeline 223 are both connected to the primary pure water tank 222, the primary pure water continuously circulates inside the primary pipeline 223. Each department in the hospital obtains the primary pure water inside the primary pipeline 223 through the primary pure water supply devices 224 for medical use.
[0053] In some embodiments, as Figure 1 shown, the water supply system further includes an acidification module 230. The acidification module 230 includes an acidified water generator 231, an acidification pipeline 232, and a plurality of acidified water supply devices 233. The inlet of the acidified water generator 231 is connected to the outlet of a part of the primary pipeline 223, and the outlet of the acidified water generator 231 is connected to the inlet of a part of the primary pipeline 223. The inlet and the outlet of the acidification pipeline 232 are both connected to the acidified water generator 231. A plurality of acidified water supply devices 233 are all arranged on the acidification pipeline 232. The acidified water generator 231 is used to convert the primary pure water into acidified water, and the acidified water supply devices 233 are used to output the acidified water circulating inside the acidification pipeline 232 to the outside. Each department in the hospital obtains the acidified water inside the acidification pipeline 232 through the acidified water supply devices 233 for medical use. The primary pure water that is not acidified inside the acidified water generator 231 then returns to the primary pure water tank 222 through the inlet of the primary pipeline 223. It should be noted that the primary pure water in the primary pure water tank 222 enters the primary pipeline 223 through the outlet of the primary pipeline 223, and the primary pure water circulating inside the primary pipeline 223 returns to the primary pure water tank 222 through the inlet of the primary pipeline 223.
[0054] In some embodiments, as Figure 1As shown in the figure, the water supply system further includes a primary pure water tank 310, a secondary reverse osmosis module 300, and a secondary pure water distribution station 330. The outlets of multiple primary reverse osmosis skids 210 are also connected to the primary pure water tank 310. The secondary reverse osmosis module 300 is composed of multiple secondary reverse osmosis skids 320 assembled together. The inlets of multiple secondary reverse osmosis skids 320 are all connected to the primary pure water tank 310. The secondary reverse osmosis skid 320 is used to filter and convert the primary pure water into secondary pure water. The outlets of multiple secondary reverse osmosis skids 320 are all connected to the secondary pure water distribution station 330, and the secondary pure water distribution station 330 is used to output the secondary pure water externally. The primary pure water obtained by primary reverse osmosis filtration enters the primary pure water tank 310. The secondary reverse osmosis skid 320 performs secondary reverse osmosis filtration on the primary pure water in the primary pure water tank 310 to obtain secondary pure water, and transports the secondary pure water to the secondary pure water distribution station 330 for use by each department in the hospital.
[0055] In some embodiments, the secondary reverse osmosis skid 320 includes a secondary high-pressure pump and a secondary reverse osmosis membrane module. The secondary high-pressure pump and the secondary reverse osmosis membrane module are connected in sequence. The water inlet of the secondary high-pressure pump is connected to the primary pure water tank 310, and the water outlet of the secondary reverse osmosis membrane module is connected to the secondary pure water distribution station 330. The secondary high-pressure pump transports the primary pure water in the primary pure water tank 310 to the secondary reverse osmosis membrane module. The secondary reverse osmosis membrane module performs secondary reverse osmosis filtration on the primary water to obtain secondary pure water, and transports the secondary pure water to the secondary pure water distribution station 330 for use by each department in the hospital.
[0056] In some embodiments, as Figure 1 shown, the secondary pure water distribution station 330 is composed of multiple secondary pure water distribution skids 331 assembled together; the secondary pure water distribution skid 331 includes a secondary pure water tank 332, a secondary pipeline 333, and multiple secondary pure water supply devices 334. The outlets of multiple secondary reverse osmosis skids 320 are all connected to the secondary pure water tank 332. The outlet and inlet of the secondary pipeline 333 are both connected to the secondary pure water tank 332. Multiple secondary pure water supply devices 334 are all arranged on the secondary pipeline 333, and the secondary pure water supply device 334 is used to output externally the secondary pure water circulating inside the secondary pipeline 333. The secondary pure water obtained by secondary reverse osmosis filtration enters the secondary pure water tank 332. Since the outlet and inlet of the secondary pipeline 333 are both connected to the secondary pure water tank 332, the secondary pure water continuously circulates in the secondary pipeline 333. Each department in the hospital obtains the secondary pure water in the secondary pipeline 333 through the secondary pure water supply device 334 for medical use.
[0057] The conductivity of the primary pure water can be controlled below 10 μS / cm, the resistivity of the secondary pure water can reach above 1 MΩ·cm, the desalination rate reaches above 99%, and the membrane recovery rate exceeds 65%. The primary pure water and the secondary pure water can meet the needs of most departments in the hospital.
[0058] It should be noted that both the primary pure water distribution station 220 and the secondary pure water distribution station 330 are composed of a pure water water tank, a disinfection device and a pump set, and are process nodes for distributing and circulating qualified pure water. The distribution station is required to maintain the water supply quality, and when the water demand of hospital departments is large, the return water volume to the pure water distribution station is reduced to meet the maximum peak water consumption requirements of the system. It mainly monitors the water quality online in real time, and disinfects or sterilizes periodically to control the microbial load of the system, generally once a week, and specifically judged according to the results of water quality monitoring.
[0059] In some embodiments, as Figure 1 shown, the water supply system further includes a cleaning module 340, and the cleaning module 340 includes a cleaning water tank 341 and a cleaning filter 342. The first water inlet of the cleaning water tank 341 is communicated with the primary pure water tank 310, and the water outlet of the cleaning water tank 341 is communicated with a plurality of primary reverse osmosis skids 210. The inlet of the cleaning filter 342 is communicated with a plurality of primary reverse osmosis skids 210, and the outlet of the cleaning filter 342 is communicated with the second water inlet of the cleaning water tank 341. As the primary reverse osmosis membrane module in the primary reverse osmosis skid 210 is continuously used, scale, microorganisms and other impurities will be generated in the primary reverse osmosis membrane module. The primary pure water in the primary pure water tank 310 enters the cleaning water tank 341 for disinfection, and the disinfected primary pure water enters the primary reverse osmosis skid 210 to clean the primary reverse osmosis membrane module. The waste water generated by the cleaning is filtered by the cleaning filter 342 and then returned to the cleaning water tank 341. By continuously circulating the primary pure water among the cleaning water tank 341, the primary reverse osmosis membrane module and the cleaning filter 342, the primary reverse osmosis membrane module is cleaned. Sodium hypochlorite or sodium hydroxide disinfectant can be placed in the cleaning water tank 341 to disinfect the primary pure water.
[0060] In some embodiments, as Figure 1 shown, the water supply system further includes a plurality of PH adjustment modules 350, and the plurality of PH adjustment modules 350 are respectively arranged at the inlets of the secondary reverse osmosis skids 320, and the PH adjustment modules 350 are used to adjust the PH value of the secondary pure water. The primary pure water obtained by primary reverse osmosis filtration is acidic, and the primary pure water is adjusted by the PH adjustment module 350 so that the PH value of the primary pure water is within the range of 4-10.
[0061] It should be noted that Figure 3 is a connection schematic diagram of the thermal disinfection module. The raw water tank 110 is communicated with the raw water source 111 to obtain raw water from the raw water source 111. The raw water is Figure 2 the tap water in
[0062] In some embodiments, as Figure 3As shown, the water supply system further includes a heat disinfection module 360, which includes a heat disinfection unit 361 and a heat disinfection pipeline 362. The heat disinfection unit 361 is arranged between the second-stage reverse osmosis skid 320 and the second-stage pure water supply device 334.

[0063] It should be noted that the second-stage pure water supply device 334 can be Figure 3 the dialysis water supply device provided at each bed, that is, the second-stage pure water can be used as dialysis water. In addition, the first-stage pure water can be used as biochemical test water, pathology department water, central supply room water, surgical irrigation water, DSI catheter irrigation water, dental irrigation water, obstetric baby washing water, preparation room water, etc.
[0064] In some embodiments, as Figure 1 shown, the water supply system further includes a second-stage pure water tank 410, an EDI module 400, and an EDI pure water distribution station 430. The outlets of multiple second-stage reverse osmosis skids 320 are also connected to the second-stage pure water tank 410. The EDI module 400 is composed of multiple EDI skids 420 assembled in a skid-mounted manner. The inlets of multiple EDI skids 420 are all connected to the second-stage pure water tank 410. The EDI skid 420 is used to filter and convert the second-stage pure water into EDI pure water. The outlets of multiple EDI skids 420 are all connected to the EDI pure water distribution station 430. The EDI pure water distribution station 430 is used to output EDI pure water externally. The EDI module 400 removes ions from the second-stage pure water in the second-stage pure water tank 410 to obtain EDI pure water and transports the EDI pure water to the EDI pure water distribution station 430 for use by each department in the hospital.
[0065] In some embodiments, as Figure 1 shown, the EDI skid 420 includes an EDI pump and an EDI deionization unit. The EDI pump and the EDI deionization unit are connected in sequence. The water inlet of the EDI pump is connected to the second-stage pure water tank 410. The water outlet of the EDI deionization unit is connected to the EDI pure water distribution station 430. The EDI deionization unit is also connected to the concentrated water tank 700. The EDI pump transports the second-stage pure water in the second-stage pure water tank 410 to the EDI deionization unit. The EDI deionization unit conducts deionization on the second-stage pure water to obtain EDI pure water and transports the EDI pure water to the EDI pure water distribution station 430 for use by each department in the hospital.
[0066] EDI pure water is high-purity water prepared by using the electro-deionization technology. The EDI technology is a new desalination process that combines electrodialysis and ion exchange. Under the action of an electric field, the cations and anions in water molecules move towards the cathode and anode respectively, and through the ion exchange membrane and the ion selective membrane, the separation and removal of ions are achieved. The treated water entering the EDI deionization unit is divided into a concentrated chamber and a dilute chamber inside. The hydrogen ions and hydroxide ions generated by the ionization of water in the concentrated chamber, under the action of the electric field, enter the dilute chamber through the cation exchange membrane and the anion exchange membrane respectively, and exchange with the cations and anions in the dilute chamber, so as to achieve the purpose of removing ions. At the same time, through the electrochemical reaction, the generated hydrogen ions and hydroxide ions are converted into water, realizing the removal of ions and the regeneration of water. EDI pure water has higher purity and better stability. Generally speaking, the conductivity of EDI pure water can be controlled below 0.1 μS / cm, and the resistivity can reach above 18 MΩ·cm. Water of this purity can almost remove all ions and impurities, reaching a very high purity standard. When higher-standard pure water is required in hospital departments, it can be achieved through the combined process of reverse osmosis filtration technology and electro-deionization technology.
[0067] In some embodiments, the EDI pure water distribution station 430 is composed of a plurality of EDI pure water distribution skids 431 assembled by skid-mounted combination; the EDI pure water distribution skid 431 includes an EDI pure water tank 432, an EDI pipeline 433, and a plurality of EDI pure water supply devices 434. The outlets of a plurality of EDI skids 420 are all communicated with the EDI pure water tank 432. The outlet and the inlet of the EDI pipeline 433 are both communicated with the EDI pure water tank 432. A plurality of EDI pure water supply devices 434 are all arranged on the EDI pipeline 433. The EDI pure water supply device 434 is used to output the EDI pure water circulating inside the EDI pipeline 433 to the outside. The EDI pure water obtained by deionization enters the EDI pure water tank 432. Since the outlet and the inlet of the EDI pipeline 433 are both communicated with the EDI pure water tank 432, the EDI pure water continuously circulates in the EDI pipeline 433. Each department in the hospital obtains the EDI pure water in the EDI pipeline 433 through the EDI pure water supply device 434 for medical use.

The first outlet is communicated with the primary pure water distribution station 220, the second outlet is communicated with the secondary pure water distribution station 330, and the third outlet is communicated with the EDI pure water distribution station 430. The ozone generator 520 is used to prepare oxygen into ozone and transport the ozone to the primary pure water distribution station 220, the secondary pure water distribution station 330, and the EDI pure water distribution station 430 for disinfection of the above distribution stations.
[0069] Figure 5 For Figure 1 the three-dimensional structural schematic diagram of the pretreatment skid. In some embodiments, as Figure 1 and Figure 5 shown, the pretreatment skid 120 includes a front pump 121, a multi-media filter 122, a carbon filter 123, a softener 124, and a precision filter 125. The front pump 121, the multi-media filter 122, the carbon filter 123, the softener 124, and the precision filter 125 are connected in sequence. The water inlet of the front pump 121 is communicated with the raw water tank 110, and the water outlet of the precision filter 125 is communicated with the softened water tank 130. The front pump 121 transports raw water to the multi-media filter 122, and the raw water is converted into softened water after passing through the multi-media filter 122, the carbon filter 123, the softener 124, and the precision filter 125 in sequence. Specifically, the multi-media filter removes suspended particles with a size > 25μm and substances such as mud and sand in the raw water; the activated carbon filter is a chlorine removal device that removes the odor and by-products of chlorine in the raw water, making the residual chlorine value in the raw water < 0.1mg / L, meeting the requirements of the feed water for the first-stage reverse osmosis filtration; the softener exchanges Ca + in the water through the ion exchange resin + , Mg 2+ etc., so that the hardness of the effluent ≤ 0.03mmol / L; the 5μm filter element of the precision filter filters the raw water to protect the first-stage reverse osmosis membrane and prevent scaling on the surface of the first-stage reverse osmosis membrane. The raw water treated above is converted into softened water, and the softened water meets the requirements of the feed water for the first-stage reverse osmosis filtration.
[0070] In some embodiments, as Figure 1As shown in the figure, the pre-pump 121, multi-media filter 122, carbon filter 123, and softener 124 are all connected to the sedimentation tank 600, and multiple primary reverse osmosis skids 210 are all connected to the concentrated water tank 700. The wastewater generated by the filtration of the pre-pump 121, multi-media filter 122, carbon filter 123, and softener 124 enters the sedimentation tank 600 and is discharged. The concentrated water generated by the filtration of multiple primary reverse osmosis skids 210 enters the concentrated water tank 700 for use. The sedimentation tank 600 is connected to the sewage pipe network 610 so that the sewage inside the sedimentation tank 600 can be discharged to the sewage pipe network 610. The concentrated water tank 700 is connected to the concentrated water supply device 710 so that each department of the hospital can obtain concentrated water through the concentrated water supply device 710 for use.
[0071] It should be noted that the existing technology is an engineering project with disadvantages such as a long design cycle and construction cycle. The process equipment is single-set without backup. Moreover, there are a series of uncertain factors in on-site construction, which may lead to the operation start time not meeting the hospital's requirements. The water supply system provided by the embodiment of the present utility model realizes the goal of centralized water production and quality-separated water supply for the whole hospital through a modular skid-mounted process. The skid-mounted module generally includes a large number of loose materials such as main process equipment, ladders and platforms, process pipelines, valve automatic control instrument equipment, cables, distribution boxes, junction boxes, and skid steel structure bases, and it is an integrated module with valves, pumps, and other equipment already installed. When the skid-mounted module is connected to other equipment on the system, there is no need to install valves, instruments, and other equipment in the middle, and only one skid base is required to complete the overall lifting and connection. The on-site workload is small, and only the external connection of pipelines and electricity needs to be completed. It can be parallel to other work, greatly saving the construction period and reducing costs.
[0072] Compared with the existing technology that conducts overall design according to the water supply requirement, constructs a set of treatment equipment to meet the water consumption, and then supplies water to the hospital according to different water qualities. In the water supply system provided by the embodiment of the present utility model, modules with the same function can be combined in a skid-mounted manner to meet the water consumption requirements of different hospitals, and then through the distribution module of each type of water, it is distributed to the using departments to achieve the goal of centralized water production and quality-separated water supply. For example, for a water supply system with a water production capacity of 1 ton per hour, the water production capacity of the water supply system is increased to 2 tons per hour through skid-mounted combination. Skids with the same function can be combined in parallel through pipelines.
[0073] The above are only the preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model are included in the protection scope of the present utility model.
