The inventor of the scheme finds that in the prior art, a method for preparing water for injection by adopting a distillation technology is adopted to derive two branches of a multi-effect distilled water machine and a hot-press water machine. However, both branches have very high energy consumption, and the multi-effect distillation machine needs to consume a large amount of industrial steam, and the hot-press type water machine consumes a large amount of electric energy, so that the production cost is increased, which is unfavorable for sustainable development of enterprises. The embodiment of the utility model provides the following scheme:
as shown in fig. 1, an embodiment of the present utility model provides a water for injection preparation system, which includes a pretreatment unit and a preparation unit, wherein the pretreatment unit is connected to the preparation unit. The pretreatment unit comprises a source water tank 1, a chlorine-containing medicament adding device 2, a source water pump 3, a first heat exchanger 4 and a pretreatment filter 5 which are connected in sequence.
The chlorine-containing chemical adding device 2 adds residual chlorine, such as sodium hypochlorite, to the water from the source water tank 1 to inhibit the growth of microorganisms. The source water pump 3 conveys the source water in the source water tank 1 to the first heat exchanger 4 to adjust the outlet water temperature to be about 25 ℃. In addition, if cooling is required in summer and heating is required in winter, the optimal separation effect of ultrafiltration is satisfied. The source water then enters a pretreatment filter 5 to remove some particulate impurities from the source water.
The pretreatment filter 5 includes a mechanical filter 51 and a second ultrafilter 52, the input end of the mechanical filter 51 is connected to the first heat exchanger 4, the output end of the mechanical filter 51 is connected to the input end of the second ultrafilter 52, and the output end of the second ultrafilter 52 is connected to the input end of the water filter tank 12. The output of the mechanical filter 51 is connected to the input of the source water tank 1, forming a loop that can be used to homogenize the concentration of sodium hypochlorite in the body of water. Secondly, when the first heat exchanger 4 is just started, the temperature of the first heat exchanger is relatively passive, and the water enters the second ultrafilter 52 after the temperature of the water body is stable, so that the second ultrafilter 52 is prevented from being damaged due to the temperature.
The mechanical filter 51 replaces the traditional multi-medium filter which is easy to collect dirt in the bed layer, is convenient to use and regenerate, is convenient for automatic control, and occupies a much smaller space. The mechanical filter 51 may set the period from backwash depending on the time of use or the quality of the effluent. The two parallel self-back washing filters work and back washing work alternately, and can be disassembled for cleaning if necessary.
The second ultrafilter 52 replaces the conventional fixed bed activated carbon filter, which on the one hand is a filter itself prone to microorganism proliferation and on the other hand the product water is in the same chamber as the microorganism enriched layer, avoiding the possibility of cross contamination.
In the ultrafiltration process, the aqueous solution flows through the membrane surface under the pushing of pressure, the solvent (water) smaller than the membrane pores and the micromolecular solute permeate the membrane to become purified liquid (filtered liquid), and the solute and solute groups larger than the membrane pores are trapped and discharged along with the water flow to become concentrated liquid. The ultrafiltration process is dynamic filtration, and the separation is accomplished in a flowing state. The solute is only deposited on the membrane surface in a limited way, the ultrafiltration rate decays to a certain extent to approach equilibrium, and can be recovered by washing.
The pretreatment unit further comprises a water filter tank 12, a second heat exchanger 19 and an electrolytic descaling device 6. The input end of the water filtering tank 12 is connected with the pretreatment filter 5, namely, the second ultrafilter 52, the output end of the water filtering tank 12 is connected with the second heat exchanger 19 through the first booster pump 13, the second heat exchanger 19 is connected with the electrolytic descaling device 6, and the electrolytic descaling device 6 is connected with the preparation unit.
The output of the water filter tank 12 is connected to a second ultrafilter 52 by a backwash pump 18, and the backwash pump 18 is used to backwash the pre-treatment filter 5.
The water filter tank 12 connected downstream of the second ultrafilter 52 has two functions, on the one hand the ultrafilter itself needs to be rinsed with clean water and on the other hand it needs to take over the pasteurization cycle of the downstream preparation unit. The water in the water filtering tank 12 enters the electrolytic descaling device 6 after being sent into the second heat exchanger 19, the second heat exchanger 19 is mainly started during pasteurization, the upstream water temperature does not need to be started when the temperature of the water is slightly changed at ordinary times, or a cooling function is started when the water is circulated in a preparation system for a long time so as to control the water temperature rise caused by mechanical work of the system.
The electrolytic descaling device 6 adopts an electrolytic descaling instrument to replace the traditional fixed bed softener. The conventional fixed bed softener is also a warm bed of microorganisms and its regeneration produces much waste water with salts. This wastewater contains a high concentration of monovalent metal ions, which are difficult to remove from the water by typical wastewater treatment. Electrolytic descaling is based on the concentration of electric scale on the cathode, which is then removed by manual or automatic means. This process also reduces contaminants with high silica, ferrite and manganese content. This is a particular advantage because removal of these impurities is difficult to accomplish with typical softeners or without the addition of scale inhibitors.
The output end of the electrolytic descaling device 6 is connected with the input end of the water filtering tank 12 to form a loop. The return flow is continuously operated at ordinary times if the system is not producing water, thereby continuously reducing the concentration of calcium and magnesium ions in the ultrafiltration tank so that the return flow is relied upon to reduce scale in the system. When the system needs to produce water, the return circuit also maintains a certain flow of backwater.
The preparation unit comprises a residual chlorine remover 7, a particulate filter 8, a plurality of reverse osmosis devices 9, an EDI ultra-pure water device 10 and an injection water tank 11 which are sequentially connected, wherein the reverse osmosis devices 9 comprise a multi-section reverse osmosis unit.
The residual chlorine remover 7 adopts a medium-pressure ultraviolet lamp, the particulate filter 8 adopts a cartridge filter, and the water passing through the electrolytic descaling device 6 flows through the residual chlorine remover 7 during water production. Under the action of the medium-pressure ultraviolet lamp, residual chlorine in the water body can be removed, TOC (total organic carbon) in the water body can be degraded, and gram-negative bacteria in the water body can be killed.
The number of the reverse osmosis devices 9 is preferably two or more than two, and two reverse osmosis devices 91 and 92 are respectively arranged, so that good effects can be achieved under the condition of low cost, and the first reverse osmosis device 91 is connected with the second reverse osmosis device 92.
The number of the reverse osmosis units of the primary reverse osmosis device 91 is preferably two, or more than two, for example, three, and the arrangement of two sections can achieve good effect under the condition of lower cost. The first stage reverse osmosis device 91 is a first stage reverse osmosis unit 911 and a second stage reverse osmosis unit 912, respectively, and the first stage reverse osmosis unit 911 is connected to the second stage reverse osmosis unit 912.
The number of the reverse osmosis units of the secondary reverse osmosis device 92 is preferably two, or more than two, for example, three, so that the arrangement of two stages can achieve good effect under the condition of lower cost. The second-stage reverse osmosis device 92 is a first-stage second-stage reverse osmosis unit 921 and a second-stage reverse osmosis unit 922, respectively, and the first-stage second-stage reverse osmosis unit 921 is connected to the second-stage reverse osmosis unit 922.
The input end of the first stage reverse osmosis unit 911 is connected to the particulate filter 8 through the first high pressure pump 16, the first stage reverse osmosis unit 911 and the second stage reverse osmosis unit 912 produce water and are combined and then connected to the first stage second reverse osmosis unit 921 through the second high pressure pump 17, and the produced water output ends of the first stage second reverse osmosis unit 921 and the second stage second reverse osmosis unit 922 are combined and then connected to the EDI ultra-pure water device 10.
The finished product injection water obtained after the pretreated water enters the first stage reverse osmosis unit 911 is input into the second stage reverse osmosis device 92, and then is conveyed to the EDI ultra-pure water device 10, and the concentrated water obtained through the second stage reverse osmosis unit 912 is relatively dirty with poor quality and is directly discharged.
The concentrate output of the second stage reverse osmosis unit 922 is connected to the input of the water filter tank 12. Since the water quality of the first stage second stage reverse osmosis unit 921 output to the second stage reverse osmosis unit 922 is good, the concentrate water obtained through the second stage reverse osmosis unit 922 is returned to the water filtering tank 12. The output end of the injection water tank 11 is connected with the input end of the water filtering tank 12 to form a loop.
The preparation unit further comprises a heat source removing terminal ultrafilter 14, wherein the input end of the heat source removing terminal ultrafilter 14 is connected with the output end of the EDI ultra-pure water device 10 through a second booster pump 15, and the output end of the heat source removing terminal ultrafilter 14 is connected with the injection water tank 11 when producing water; the heat source removing terminal ultrafilter 14 is connected to the water filtering tank 12 during the internal circulation of the output end, the heat source removing terminal ultrafilter 14 is used for removing the heat source in the finished product injection water obtained after the heat source in the water is removed after passing through the whole reverse osmosis device 9 and the EDI ultra-pure water device 10, and finally the finished product injection water is conveyed to the injection water tank 11 for storage.
During the system operation, add chlorine-containing medicament on the output passageway of source water jar 1 when the preliminary treatment, chlorine-containing medicament adopts sodium hypochlorite, adjusts the temperature to about 25 degrees through first heat exchanger 4, filters the impurity in the source water through mechanical filter 51 and second ultrafilter 52, carries out electrolytic descaling through relieving salt device 6 and obtains the preliminary treatment water.
The filtered water in the filtered water tank 12 is passed through a backwash pump 18 to clean the pretreatment filter 5 for filtering impurities in the source water. The filtered water after the impurity filtration is stored in the water filter tank 12, and scale in the water is reduced by a circuit formed between the water filter tank 12 and the residual chlorine remover 7. The chlorine concentration in the water is equalized by a circuit formed between the pretreatment filter 5 for filtering impurities in the water and the source water tank 1, i.e., a circuit formed between the mechanical filter 51 and the source water tank 1.
The residual chlorine in the pretreated water is removed by a residual chlorine remover 7 during preparation, the particulate matters are removed by a particulate matter filter 8, and the pretreated water is subjected to reverse osmosis treatment to obtain the finished product of the water for injection. When the water is subjected to reverse osmosis treatment, the pretreated water enters a primary reverse osmosis device 91, a secondary reverse osmosis device 92, an EDI ultra-pure water device 10 and a heat source removing terminal ultra-filter 14 for treatment to obtain finished product injection water; the concentrate obtained through the second stage reverse osmosis unit 912 is discharged, and the concentrate obtained through the second stage reverse osmosis unit 922 is returned to the water filter tank 12.
The reverse osmosis produced water is further purified by the EDI ultra-pure water device 10, and the EDI produced water is subjected to heat source removal by the heat source removal terminal ultra-filter 14 to finally obtain finished product injection water, and then the finished product injection water is stored in the injection water tank.
