DETAILED DESCRIPTION
[0024] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0025] To achieve the above-mentioned purpose, the embodiment of the present invention adopts the following technical scheme: a disinfectant production system, including a raw water tank 10, and also including a front-end processing mechanism, a dialysis water tank 30, a preparation mechanism, a filling and filtering device and a filling machine 50. Further, the front-end processing mechanism includes a front-end filtering device, a multi-stage reverse osmosis device and an EDI device 230, wherein the front-end filtering device is arranged at the output end of the raw water tank 10, the multi-stage reverse osmosis device is arranged at the output end of the front-end filtering device, the EDI device 230 is arranged at the output end of the multi-stage reverse osmosis device, the dialysis water tank is arranged at the output end of the EDI device 230, and the preparation mechanism includes a preparation tank 410 and a mixing tank 420. Specifically, the number of preparation tanks is several, and several preparation tanks are connected to the output end of the dialysis water tank 30. At the same time, the mixing tank 420 is also arranged at the output end of the dialysis water tank 30, that is, the liquid output from the dialysis water tank can enter several respectively. It should be noted that in the preparation tank 410 and the mixing tank 420, the liquid in several of the preparation tanks is filtered and then transported to the mixing tank for mixing treatment. The filling and filtering device is arranged at the output end of the mixing tank 420, and the filling machine is arranged at the output end of the filling and filtering device. When in use, the medicinal liquid raw materials transported by the raw water tank 10 enter the front-end processing mechanism, and the front-end filtering device, the multi-stage reverse osmosis device and the EDI device are used to remove impurities, color, smell, residual chlorine, calcium, magnesium ions and suspended colloids in the water body. After filtering, the water body enters the dialysis water tank 30 and is transported to various water use points by pumps. Then the medicinal liquid enters the preparation tank 410 and the mixing tank 420 of the preparation mechanism. At the same time, the medicinal liquid in the preparation tank can be transported to the mixing tank for mixing reaction after filtration. The medicinal liquid after mixing enters the filling and filtering device for further filtering treatment, and enters the filling machine for filling treatment after the filtration is completed. The finished product after filling can be transported to the subsequent process.
[0026] It should be noted that EDI devices utilize continuous electro-deionization technology, a technique for producing ultrapure water. This technology utilizes the selective permeation of cations and anions by cation and anion membranes, and the exchange of ions in water by ion exchange resins. Under the influence of an electric field, ion migration is achieved, resulting in deep water purification and desalination. Simultaneously, the hydrogen and hydroxide ions generated by water electrolysis continuously regenerate the loaded resin. Because this technology is currently available, we will not elaborate on it here.
[0027] As a preferred technical solution of this embodiment, the front-end filtering device includes a multi-media filter 211, an activated carbon filter 212 and a precision filter 213. The multi-media filter 211 is arranged at the output end of the raw water tank 10, the activated carbon filter 212 is arranged at the output end of the multi-media filter, and the precision filter 213 is arranged at the output end of the activated carbon filter. It should be noted that the multi-media filter 211 uses one or more filter media to pass water with high turbidity through a certain thickness of granular or non-granular material under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Among them, commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment turbidity removal, softening water, and pre-stage pretreatment of pure water;
[0028] The activated carbon filter 212 is a tank-shaped filtering device, the shell of which is generally made of stainless steel or fiberglass, and is filled with activated carbon. It is used to filter free matter, microorganisms, and some heavy metal ions in the water, and can effectively reduce the color of the water.
[0029] Precision filter 213 is also called security filter. The shell of the cylinder is generally made of stainless steel. The interior uses tubular filter elements such as PP melt-blown, wire-sintered, folded, titanium filter element, activated carbon filter element, etc. as filter elements. Different filter elements are selected according to different filter media and design processes to meet the requirements of effluent water quality.
[0030] Furthermore, the multi-stage reverse osmosis device includes a first-stage reverse osmosis device 221 and a second-stage reverse osmosis device 222. The first-stage reverse osmosis device 221 is arranged at the output end of the precision filter 213, and the second-stage reverse osmosis device 222 is arranged at the output end of the first-stage reverse osmosis device. In this way, the first-stage reverse osmosis device, the second-stage reverse osmosis device and the EDI device remove impurities, color, smell, residual chlorine, calcium, magnesium ions and suspended colloids in the water source before the liquid enters the dialysis water tank 30.
[0031] Furthermore, the output end of the dialysis water tank 30 is also provided with a first reflux pipeline 310 for returning the water to its own tank body. The purpose of the reflux circulation of the dialysis water is, on the one hand, to better sterilize it, so that each cycle is sterilized and the sterilization is more thorough, and on the other hand, to balance the pressure and reduce the workload of the pump.
[0032] As a preferred technical solution of this embodiment, the output ends of several of the preparation tanks 410 are connected to preparation filtering devices 430, and the output ends of the preparation filtering devices are connected to the mixing tank 420. By arranging the preparation filtering device at the front end of the mixing tank 420, larger particles and microparticles can be prevented from entering the mixing tank 420. Among them, the filter element in the preparation filtering device is a polypropylene filter element with a specification of 1μm, which can solve some solid particle impurities generated during the preparation process and make the medicine liquid in the mixing tank more uniform. In this way, combined with the front-end filtering device, coarse filtration intercepts a part of the impurities and improves the filtration efficiency of the rear end.
[0033] Furthermore, the filling and filtering device includes a primary filtering device 610 and a secondary filtering device 620. The primary filtering device 610 is arranged at the output end of the mixing tank 420, and the secondary filtering device 620 is arranged at the output end of the primary filtering device. At the same time, a second return line 440 for returning to its own tank body is provided at the output end of the mixing tank 420, and a third return line 630 for returning to the mixing tank 420 is provided at the output end of the secondary filtering device 620. Specifically, before filling, the mixed and treated medicinal liquid in the mixing tank is circulated and filtered through the primary filtering device and the secondary filtering device, which can effectively remove particles, microorganisms, etc. in the medicinal liquid to improve product quality. Part of the filtered medicinal liquid is output to the filling machine for filling, and part is returned to the mixing tank through the third return line. The purpose of circulation is to reduce the workload of the pump and make the filtration of particles and microorganisms in the medicinal liquid more thorough. In addition, the second return line at the output end of the mixing tank can also realize the return of the medicinal liquid at its own output end to further improve the effect of circulation filtration.
[0034] It should be noted that the filling filter device uses two-stage filtration technology. The first stage uses a 1μm filter element, which is primarily used to remove particulates. The second stage uses a 0.45μm polypropylene filter element and a 0.22μm polyethersulfone filter element, which are primarily used to filter particulates and microorganisms from the liquid medicine. At the same time, the filter elements of these two filters can be equipped with an integrity tester to test and ensure the integrity of the filter elements. The use of two-stage filtration technology can better remove particulates and microorganisms from the liquid medicine, better ensuring product quality.
[0035] During use, the front-end processing mechanism uses a multi-media filter 211, an activated carbon filter 212, and a precision filter 213 for filtration treatment, and passes through a primary reverse osmosis device 221, a secondary reverse osmosis device 222, and an EDI device 230 to remove impurities, color, smell, and taste, residual chlorine, calcium, magnesium ions, and suspended colloids in the water source; after the front-end processing mechanism filters the water source, it is pumped to various water use points and then returned to the dialysis water tank 30. During the preparation process, a preparation filtering device 430 is added between the preparation tank 410 and the mixing tank 420 to remove some solid particle impurities generated during the preparation process, making the liquid medicine in the mixing tank 420 more uniform. Combined with the front-end coarse filtration to intercept some impurities, the filtration efficiency of the back-end is improved; during the filling process, the liquid medicine in the mixing tank 420 passes through the primary filtration device 610 and the secondary filtration device 620 for circulation filtration, with part of it output to the filling machine 50 for filling, and part of it returned to the mixing tank 420, so that the particles and microorganisms in the liquid medicine are filtered more thoroughly.
[0036] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
