Abstract

This invention relates to the field of water purification equipment technology, and discloses a purification machine and method for converting chlorine-containing water into hydrogen chloride-containing liquid. The purification method involves connecting municipal tap water, surface water, or groundwater to a pre-treatment tank via an input pipe equipped with valve A for filtration. The water then enters a reaction tank via valve B. An external chlorine generator is connected to a chlorine detection and regulator via valve C. After the chlorine detection and regulator, a chlorine pipe leads into the reaction tank, where chlorine disinfects the water and reacts with it to produce hydrochloric acid and hypochlorous acid. The water then undergoes deep filtration in a high-adsorption chlorine integrated chamber.

Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and more specifically, to a purification machine and method for converting chlorine-containing water into hydrogen chloride-containing liquid. Background Technology

[0002] Water purification equipment is a device used to improve water quality. Its main function is to remove pollutants, impurities, and harmful substances present in tap water, thereby providing safe and clean drinking water. With the acceleration of industrialization and urbanization, water pollution problems are becoming increasingly serious, and the demand for safe drinking water is constantly increasing, leading to a growing demand for water purification equipment.

[0003] Because drinking water requires chlorination for disinfection, according to my country's GB5749-85 standard, "the residual chlorine in the water at the end of the pipe network should not be lower than 0.05 mg / L." Maintaining a certain level of residual chlorine at the end of urban water pipes is crucial to control bacterial growth and prevent contamination, as residual chlorine can generate a certain amount of hydrogen chloride in the water. However, water purification equipment specifically designed for water containing chlorine that can generate hydrogen chloride has not yet been adequately developed. Drinking water quality is mostly controlled by residual chlorine to ensure the water at the point of contact has antibacterial and sterilizing effects. Due to the large area of ​​the pipe network, the residual chlorine content in certain areas may vary, leading to unstable water quality standards. This results in problems such as poor sterilization effects or excessively high residual chlorine levels, affecting the normal consumption of drinking water. In particular, boiling water is often used to eliminate residual chlorine, but this method destroys nutrients in the water and produces harmful substances such as nitrites. Summary of the Invention

[0004] This invention discloses a purification device and method for converting chlorine-containing aqueous solution into hydrogen chloride, thereby solving the technical problems mentioned in the background art.

[0005] The first aspect of the present invention discloses a purification machine for adsorbing chlorine and converting it into hydrogen chloride-containing water, including a frame, a reaction tank is arranged in the frame, a chlorine supply component is arranged at the bottom of the reaction tank, and an inlet pipe and an outlet pipe are respectively installed on the surface of the reaction tank;

[0006] A pretreatment box is located on one side of the frame. The pretreatment box is equipped with a backwash filter, a negative resistance scale inhibitor, and an ultrafiltration membrane. An input pipe and a connecting pipe are installed on both sides of the pretreatment box. Water is introduced through the input pipe and the connecting pipe is connected to the inlet pipe.

[0007] The reaction chamber is equipped with a partition and a pressing plate, which divide the reaction chamber into a disinfection chamber, a reaction chamber, and a high-adsorption chlorine integrated chamber. The disinfection chamber is equipped with a mixing component, which includes a motor mounted on the surface of the reaction chamber. The output end of the motor is fixedly connected to a rotating rod. One end of the rotating rod passes through the disinfection chamber and is movably connected to a mixing component. The partition is connected to the reaction chamber through a clutch component, which is used to connect or separate the disinfection chamber and the reaction chamber.

[0008] A filter assembly is disposed within the high-adsorption chlorine integrated chamber. The filter assembly includes several activated carbon filter elements disposed on the side of the extrusion plate near the high-adsorption chlorine integrated chamber. The surface of the extrusion plate is provided with through holes adapted to the inner cavity of the activated carbon filter elements. The extrusion plate is connected to the reaction chamber via a cylinder. When the cylinder outputs, the extrusion plate moves laterally within the reaction chamber, thereby gradually reducing the volume of the reaction chamber and gradually increasing the volume of the high-adsorption chlorine integrated chamber.

[0009] Several temperature-controlled photosynthetic units are installed in the reaction chamber. The temperature-controlled photosynthetic units are configured as temperature control tubes or light tubes. Through temperature control or photosynthesis, oxygen is released from the water, which can more effectively decompose HClO in the water.

[0010] A pressure regulating and storage tank is located on the side of the frame away from the pretreatment box. The water outlet pipe is connected to the pressure regulating and storage tank. A monitoring device is installed at the connection point between the water outlet pipe and the pressure regulating and storage tank.

A positive and negative pressure controller is installed inside the pressure regulating and storage tank near the output pipe.

[0011] Preferably, the mixing component includes a movable ring, which is fixedly connected to the surface of the rotating rod. A plurality of connecting rods are fixedly connected to the surface of the movable ring, and blades are fixedly connected to the surface of the connecting rods.

[0012] Preferably, the mixing component includes a movable ring, the rotating rod has a threaded groove on its surface, the movable ring is threadedly connected to the rotating rod surface, a plurality of connecting rods are fixedly connected to the surface of the movable ring, the connecting rods have blades hinged to their surfaces, and a connecting ring is rotatably connected to the bottom of the movable ring, the connecting ring being connected to the reaction chamber by a spring.

[0013] Preferably, one side of the partition extends through the reaction chamber and beyond the reaction chamber. The clutch assembly includes a connecting block fixedly connected to the side of the partition outside the reaction chamber. An electric actuator is fixedly connected to the surface of the reaction chamber, and the output end of the electric actuator is fixedly connected to the connecting block.

[0014] Preferably, the side of the partition closest to the inside of the reaction chamber is arc-shaped, and the arc bends toward the sterilization chamber.

[0015] Preferably, the inner wall of the through hole communicating with the inner cavity of the extrusion plate and the activated carbon filter element is provided with two sealing doors. The sealing doors are connected to the extrusion plate through a rotating shaft. A torsion spring is provided inside the rotating shaft. The two ends of the torsion spring are respectively connected to the rotating shaft and the extrusion plate. A plurality of temperature-controlled photosynthetic devices are adapted to a plurality of the through holes.

[0016] Preferably, the inner cavity of the activated carbon filter element is provided with several air outlet pipes, one end of which is fixedly connected to one side of the extrusion plate. A connecting pipe is fixedly connected to the side of the extrusion plate near the reaction chamber. An air chamber is opened in the extrusion plate, and the connecting pipe is connected to the air outlet pipe through the air chamber. Several air holes for gas to pass through are opened on the surface of the air outlet pipe.

[0017] Preferably, a hydrogen supply pipe is fixedly connected to the surface of the activated carbon filter element, and a number of hydrogen supply control valves are provided on one side of the reaction tank. The hydrogen supply control valves are connected to an external hydrogen supply device, and one end of the hydrogen supply control valve located inside the reaction tank is connected to the hydrogen supply pipe through a connecting hose.

[0018] Preferably, the chlorine supply assembly includes a chlorine generator disposed at the bottom of the frame body, the chlorine generator being connected to the reaction chamber via a chlorine inlet pipe, and a detection regulator being installed on the surface of the chlorine inlet pipe.

[0019] The second aspect of this invention discloses a purification method for converting chlorine-containing aqueous solution into hydrogen chloride through adsorption, comprising the following steps:

[0020] S1. A valve is connected to the municipal tap water, surface water, or groundwater input. A booster pump is installed after the A valve. A pre-backwash filter is installed after the booster pump. A negative charge layer alloy catalyst scale inhibitor is installed after the filter. An ultrafiltration membrane purifier is installed after the scale inhibitor. A control valve B is installed after the ultrafiltration membrane purifier. The reaction tank is connected after the control valve B.

[0021] S2. The external salt electrolysis chlorine generator introduces chlorine through valve C. A detection regulator and mixing device are installed at the rear end of valve C and connected to the reaction tank. The chlorine introduced through valve C is mixed with the purified water introduced through valve B to disinfect the water and facilitate the full conversion of water and chlorine to generate HCl and HClO.

[0022] S3. The chlorine-water mixture after step 2 is introduced into the high-adsorption chlorine chamber. The high-adsorption chlorine integrated chamber is equipped with a D valve on its side, which is connected to an external hydrogen production device. The hydrogen input enhances the reaction between hydrogen and chlorine to form the required pH value. The high-adsorption chlorine integrated device is mainly composed of high-adsorption activated carbon fiber (ACF), supplemented with PP cotton layer and maifan stone. Through the BET specific surface area of ​​ACF of 1500-3000 (㎡ / g), the adsorption of chlorine or residual chlorine reaches 60-97%. The residual chlorine in the water is effectively filtered and converted by the activated carbon fiber filter element, further eliminating residual chlorine.

[0023] S4. The adsorbed chlorine reaches a saturation concentration, forming a special chlorine membrane (highly efficient sterilization and disinfection). Chlorine ions / molecules that overflow from the chlorine membrane easily undergo hydrolysis in water, releasing oxygen under the action of a temperature-controlled photosynthetic device to form a stable HCl-containing solution. This solution is then connected to a positive and negative pressure regulating storage tank. The parameters of the HCl-containing solution are monitored and controlled by a detection and monitoring controller. A controllable display screen is installed on the surface of the detection and monitoring controller, displaying parameters such as water temperature, concentration, residual chlorine, pH value (adjustment gradient 6.9~0.9), and TDS, ensuring the safety and quality of the output purified HCl-containing solution.

[0024] S5, outputs aqueous solution containing HCl.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention, by incorporating a mixing component, can pressurize chlorine gas in water, preventing unreacted chlorine gas from floating on the surface of the water and causing incomplete reaction between chlorine and water, thus improving the disinfection effect of chlorine on the water. Furthermore, by using a spring, the movable ring is pushed upwards while the blades rotate downwards due to water resistance. Simultaneously, the movable ring rotates on the surface of a rotating rod with threaded grooves, causing the blades to drive the water to generate a rotating flow. This facilitates the introduction of water and chlorine gas into the reaction chamber for complete conversion and reaction to produce HCl and HClO.

[0027] This invention enhances HClO conversion by incorporating multiple components in a high-adsorption chlorine separator. Oxygen is separated and released within the integrated high-adsorption chlorine chamber, and the release of oxygen through temperature-controlled photosynthesis further decomposes HClO in the water, generating HCl and O2↑, thus reducing the HClO content and improving HCl purity. Simultaneously, residual chlorine in the water is effectively filtered and converted by an activated carbon fiber filter, further controlling the HCl purity and resulting in safer, higher-quality, and purer HCl-containing water.

[0041] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0042] This invention discloses a purification device for converting chlorine-containing aqueous solution into hydrogen chloride through adsorption. Figure 1 and Figure 2 As shown, the system includes a frame 1, a reaction chamber 2 inside the frame 1, a chlorine supply assembly at the bottom of the reaction chamber 2, an inlet pipe 21 and an outlet pipe 212 installed on the surface of the reaction chamber 2, the inlet pipe 21 being connected to an external water source or a waterworks source, and the outlet pipe 212 being connected to an external water storage device. A pretreatment tank 3 is located on one side of the frame 1, and a backwash filter 31, a negative resistance scale inhibitor 32 and an ultrafiltration membrane 33 are installed inside the pretreatment tank 3. An input pipe 34 and a connecting pipe 35 are installed on both sides of the pretreatment tank 3, and the connecting pipe 35 is connected to the inlet pipe 21.

[0043] The inlet pipe 34 is the water supply inlet for the water purifier. It is used to connect to external water sources such as municipal tap water, surface water, or groundwater to provide a water source. A booster pump can be installed at the inlet pipe 34 to improve and stabilize the water pressure of the water purifier and maintain its operation. The backwash filter 31 filters impurities in the water, maintaining the efficiency and lifespan of the subsequent filter membrane. The negative resistance scale inhibitor 32, also known as the negative charge layer alloy catalyst scale inhibitor, uses a special alloy catalyst material to generate free negative electrons and positively charged salts through the conduction of an electrically double-layer polar fluid medium under the action of water flow. This reduces crystallization, flocculation, and adhesion, reduces scale formation, and promotes the activity of the water. The ultrafiltration membrane 33, also known as the ultrafiltration membrane purifier, is equipped with an ultrafiltration membrane core to purify water in a series structure. A positive pressure control valve can be installed inside to control the backflow of the mixed liquid in the reaction tank 2 and continue filtration.

[0044] like Figure 4 and Figure 5 As shown, the reaction chamber 2 is equipped with a partition 23 and a pressing plate 26, which divide the reaction chamber 2 into a disinfection chamber 22, a reaction chamber 24, and a high-adsorption chlorine integrated chamber 25. The inlet pipe 21 is connected to the inside of the disinfection chamber 22, while the outlet pipe 212 is connected to the high-adsorption chlorine integrated chamber 25. The disinfection chamber 22 is equipped with a mixing component, which includes a motor 221 installed on the surface of the reaction chamber 2. The motor 221 is equipped with a locking device that can be used to lock its output end. The output end of the motor 221 is fixedly connected to a rotating rod 222. One end of the rotating rod 222 passes through the disinfection chamber 22. The connection between the rotating rod 222 and the reaction chamber 2 is sealed to ensure the sealing effect inside the reaction chamber 2. The mixing component is movably connected to the partition 23. The partition 23 is connected to the reaction chamber 2 through a clutch assembly, which is used to connect or separate the disinfection chamber 22 and the reaction chamber 24.

[0045] like Figure 6 and Figure 7As shown, this embodiment includes a filtration assembly disposed within a high-adsorption chlorine integrated cavity 25. The filtration assembly includes several activated carbon filter elements 261 disposed on the side of the extrusion plate 26 near the high-adsorption chlorine integrated cavity 25. Each activated carbon filter element 261 contains a super-adsorption activated carbon fiber filter membrane. The activated carbon filter elements 261 are arranged in parallel. The activated carbon filter elements 261 are used to filter residual chlorine and other impurities in the water. The surface of the extrusion plate 26 has through holes adapted to the inner cavity of the activated carbon filter elements 261. The extrusion plate 26 is connected to the reaction chamber 2 via a cylinder 28. When the cylinder 28 outputs, the extrusion plate 26 moves laterally within the reaction chamber 2, causing the volume of the reaction chamber 24 to gradually decrease, while the volume of the high-adsorption chlorine integrated cavity 25 gradually increases.

[0046] It also includes several temperature-controlled photosynthetic units 242, which are set inside the reaction chamber 24. The temperature-controlled photosynthetic units 242 are configured as temperature control tubes or light-emitting tubes. The temperature control tube is a temperature heating control tube used to heat the water source, while the light-emitting tube is a light-generating tube used to illuminate the water source. Through the action of temperature control or photosynthesis to release oxygen, the HCl in the water is decomposed more effectively, generating HCl and O2↑, reducing the HCl content and increasing the HCl purity, thus obtaining a safe, high-quality and purer HCl-containing water. The temperature-controlled photosynthetic units 242 are connected to the reaction chamber 2 via a vertical plate 241. The vertical plate 241 is fixedly connected to the inner wall of the reaction chamber 2 near the reaction chamber 24, while the temperature-controlled photosynthetic units 242 are fixedly connected to the surface of the vertical plate 241.

[0047] Specifically, external water is introduced through inlet pipe 21 into disinfection chamber 22, and chlorine gas is supplied to the water source through chlorine supply component for water disinfection. After the chlorine gas enters the water, the mixing element on the surface of rotating rod 222, driven by motor 221, mixes and stirs the chlorine gas and water, improving the mixing efficiency and thus enhancing disinfection and mixing efficiency. Subsequently, the clutch component moves partition 23 within reaction chamber 2, connecting disinfection chamber 22 and reaction chamber 24. The water solution mixed with chlorine gas in disinfection chamber 22 enters reaction chamber 24, and is then disinfected by temperature and light control. The heating effect of the combiner 242 maintains the water at a certain temperature, thereby promoting the decomposition of hypochlorous acid in the water, which in turn generates hydrogen chloride and oxygen. After the oxygen is generated, it gathers at the top of the reaction chamber 24. Subsequently, under the output action of the cylinder 28, the extrusion plate 26 is pushed to move towards the reaction chamber 24. Under the action of the reaction force, the water in the reaction chamber 24 enters the activated carbon filter element 261 through the through hole and is filtered by the activated carbon filter element 261, thereby facilitating the effective filtration of residual chlorine in the water, further reducing impurities in the water, and improving the purity of hydrogen chloride in the water.

[0048] The pressure regulating storage tank 4 is located on the side of the frame 1 away from the pretreatment box 3. The water outlet pipe 212 is connected to the pressure regulating storage tank 4. A monitoring device 41 is installed at the connection position between the water outlet pipe 212 and the pressure regulating storage tank 4. A display screen can also be installed on the surface of the pressure regulating storage tank 4. The display screen is electrically connected to the monitoring device 41. An output pipe 43 is installed on one side of the pressure regulating storage tank 4. A positive and negative pressure controller 42 is installed inside the pressure regulating storage tank 4 near the output pipe 43.

[0049] The HCl solution in reaction tank 2 is discharged into pressure regulating storage tank 4 through outlet pipe 212. The solution is monitored by detection and monitoring device 41, which detects parameters such as water temperature, concentration, residual chlorine, pH adjustment gradient (6.9-0.9), and TDS. These parameters are displayed on the screen for easy and intuitive understanding of the various indicators of the HCl solution. The solution is output through positive and negative pressure controller 42 and output from outlet pipe 43 for subsequent treatment.

[0050] like Figure 4 , Figure 5 and Figure 8 As shown, in this embodiment, the mixing component includes a movable ring 223, which is fixedly connected to the surface of the rotating rod 222. A plurality of connecting rods 224 are fixedly connected to the surface of the movable ring 223, and blades 225 are fixedly connected to the surface of the connecting rods 224.

[0051] Specifically, the output of motor 221 drives the rotating rod 222 and the movable ring 223 on its surface to rotate, which in turn drives the blade 225 to rotate around the rotating rod 222 via connecting rod 224, stirring the water and improving the efficiency of chlorine gas and water for disinfection and sterilization.

[0052] like Figure 4 , Figure 5 and Figure 9 As shown, in one parallel embodiment, the mixing component includes a movable ring 223, a rotating rod 222 with a threaded groove on its surface, the movable ring 223 being threadedly connected to the surface of the rotating rod 222, a plurality of connecting rods 224 being fixedly connected to the surface of the movable ring 223, blades 225 being hinged to the surface of the connecting rods 224, and a stop being provided on the surface of the connecting rods 224 so that the highest height of the blades 225 can only be rotated to a state parallel to the bottom of the reaction chamber 2, and a connecting ring 226 is rotatably connected to the bottom of the movable ring 223, the connecting ring 226 being connected to the reaction chamber 2 through a spring 227, the two ends of the spring 227 being fixedly connected to the connecting ring 226 and the reaction chamber 2 respectively, and the spring 227 being a rigid spring that is not easily twisted, such as a carbon steel spring or a silicon manganese steel spring.

[0053] Specifically, unlike the above embodiments, this embodiment uses a threaded connection between the movable ring 223 and the rotating rod 222. This allows the movable ring 223 on the surface of the rotating rod 222 to move downwards along the thread when the motor 221 drives the rotating rod 222 to rotate. This causes the movable ring 223 to drive the blade 225 downwards, which in turn presses down the chlorine gas in the water. As the blade 225 moves downwards, the resistance from the water causes it to rotate upwards, thus creating the effect shown in the image. Figure 7 As shown, the downward pressure of blade 225 prolongs the time chlorine is held at deeper water depths, thereby further promoting the mixing efficiency of chlorine and deep water, improving the uniformity of the reaction between water and chlorine at different depths, and enhancing the disinfection effect of chlorine in the water. Furthermore, when motor 221 drives rotating rod 222 to rotate, and movable ring 223 moves downward with the thread, connecting ring 226 moves downward accordingly, compressing spring 227. Because spring 227 is rigid and not easily twisted, it effectively prevents the rotation of connecting ring 226. After blade 225 is pressed down to a certain extent and the chlorine reaction is saturated, motor 221 stops outputting and locks rotating rod 222 through a locking device. At this time, under the rebound force of spring 227, connecting ring 226 and movable ring 223 are pushed upward, causing blade 225 to move upward. During the upward movement, blade 225 is resisted by water and rotates downward, forming a... Figure 8 As shown in the impeller state, the movable ring 223 moves up on the surface of the rotating rod 222 and is driven to rotate synchronously by the threaded groove, thereby agitating the water in the disinfection chamber 22. The water is driven by the blade 225 to form a rotating flow. At this time, the baffle 23 is opened by the clutch assembly, and the water forming the rotating flow enters the reaction chamber 24 through the opening of the baffle 23 by the guiding effect. The baffle 23 is closed in time by the clutch assembly to avoid the backflow of water, so as to achieve uniform mixing and transfer of chlorine and water.

[0054] like Figure 4 As shown, in this embodiment, one side of the partition 23 penetrates the reaction chamber 2. The connection between the partition 23 and the reaction chamber 2 is sealed by applying sealant or setting a sealing strip, and extends outside the reaction chamber 2. The clutch assembly includes a connecting block 231 fixedly connected to the side of the partition 23 located outside the reaction chamber 2. An electric push rod 232 is fixedly connected to the surface of the reaction chamber 2. The output end of the electric push rod 232 is fixedly connected to the connecting block 231. Through the output of the electric push rod 232, the connecting block 231 can be driven to push the partition 23 to move inside the reaction chamber 2, so that the partition 23 can separate or connect the sterilization chamber 22 and the reaction chamber 24.

[0055] Furthermore, the side of the partition 23 closest to the inside of the reaction chamber 2 is arc-shaped, with the arc curving towards the disinfection chamber 22. The arc-shaped partition 23 is used to guide the water flow, reduce turbulence during the rotating flow process, and improve the stability of the water flow into the reaction chamber 24.

[0056] like Figure 10 and Figure 11 As shown, in this embodiment, the inner wall of the through hole connecting the extrusion plate 26 and the inner cavity of the activated carbon filter element 261 is provided with two sealing doors 262. The sealing doors 262 are configured to open in opposite directions, and a sealing strip is provided at the contact position between the sealing doors 262 and the inner wall of the through hole. Sealing strips are also provided on the opposite sides of the two sealing doors 262 to ensure the sealing effect between the reaction chamber 24 and both sides of the activated carbon filter element 261 when the doors are closed. The sealing doors 262 are connected to the extrusion plate 26 via a rotating shaft 263. The rotating shaft 263 is fixedly connected to the surface of the sealing doors 262 and is rotatably connected to the inner wall of the through hole to rotate and open and close the sealing doors 262. A torsion spring is provided inside the rotating shaft 263, and the two ends of the torsion spring are connected to the rotating shaft 263 and the extrusion plate 26 respectively. When the torsion spring is in a relaxed state, the two sealing doors 262 are in a state of relative contact and sealing of the through hole. Several temperature-controlled photosynthetic devices 242 are adapted to several through holes.

[0057] Specifically, as the cylinder 28 outputs and pushes the extrusion plate 26 toward the reaction chamber 24, the extruded water will press against the sealing door 262 in the through hole, thereby causing the sealing door 262 to rotate and open, allowing the water in the reaction chamber 24 to enter the activated carbon filter element 261 and be filtered under pressure. In addition, as the pressure of the water on the sealing door 262 gradually decreases, the temperature control photosynthetic device 242 is adapted to the through hole, so the temperature control photosynthetic device 242 will be inserted into the through hole, thereby opening the sealing door 262 and keeping the sealing door 262 open.

[0058] Furthermore, such as Figure 7 and Figure 11 As shown in this embodiment, the inner cavity of the activated carbon filter element 261 is provided with several air outlet pipes 264. One end of the air outlet pipe 264 is fixedly connected to one side of the extrusion plate 26. A connecting pipe 265 is fixedly connected to the side of the extrusion plate 26 near the reaction chamber 24. The connecting pipe 265 is located at the upper position on the surface of the extrusion plate 26 to prevent water from mixing into its interior. An air chamber 266 is opened in the extrusion plate 26. The connecting pipe 265 is connected to the air outlet pipe 264 through the air chamber 266. The air chamber 266 connects the interior of the connecting pipe 265 and the air outlet pipe 264 respectively. Several air holes for gas passage are opened on the surface of the air outlet pipe 264.

[0059] A hydrogen supply pipe 27 is fixedly connected to the surface of the activated carbon filter element 261. Several hydrogen supply control valves 272 are provided on one side of the reaction chamber 2. The hydrogen supply control valves 272 are connected to external hydrogen supply equipment. One end of the hydrogen supply control valve 272 located inside the reaction chamber 2 is connected to the hydrogen supply pipe 27 through a connecting hose 271. The connecting hose 271 can maintain the supply of hydrogen during the movement of the activated carbon filter element 261.

[0060] Specifically, through the setting of the gas outlet pipe 264, in the reaction chamber 24, the hypochlorous acid in the aqueous solution is decomposed by controlling a certain temperature through the temperature-controlled photosynthetic device 242. The oxygen in the decomposition products floats to the top of the reaction chamber 24. When the reaction chamber 24 is squeezed by the extrusion plate 26, the oxygen in the reaction chamber 24 enters the gas chamber 266 through the connecting pipe 265, and then enters the gas outlet pipe 264 through the gas chamber 266, and is discharged into the aqueous solution through the gas hole. Then, in conjunction with the hydrogen supply control valve 272, external hydrogen is introduced into the activated carbon filter element 261 through the hydrogen supply pipe 27 to mix and react, generating water and active water molecules, further improving the reaction rate of by-products and controlling the purity of hydrogen chloride in the aqueous solution. This step is completed before filtration. After controlling the purity of hydrogen chloride, the aqueous solution is filtered to further filter out residual chlorine and improve the filtration stability of the aqueous solution.

[0061] The chlorine supply assembly includes a chlorine generator 11 located at the bottom of the frame 1. The chlorine generator 11 is used to store chlorine. The chlorine generator 11 is connected to the reaction chamber 2 through a chlorine inlet pipe 13. A detection regulator 12 is installed on the surface of the chlorine inlet pipe 13. The detection regulator 12 is used to detect key factors such as the concentration and content of chlorine generated in the chlorine generator 11, and can control the chlorine inlet flow and concentration. The detection regulator 12 is equipped with a valve. By opening and closing the valve, the chlorine in the chlorine generator 11 can be introduced into the disinfection chamber 22 through the chlorine inlet pipe 13.

[0062] Working principle:

[0063] S1; External municipal tap water, surface water, or groundwater is input into the pretreatment tank through input pipe 34. A booster pump can be installed at input pipe 34 to pressurize the water, which then passes through backwash filter 31 for filtration. The filtered water then enters negative resistance scale inhibitor 32 for scale inhibition. After negative resistance scale inhibitor 32, an ultrafiltration membrane 33 is installed for further filtration. After passing through ultrafiltration membrane 33, the water passes through connecting pipe 35 and is connected to inlet pipe 21 to enter reaction tank 2. An external chlorine generator 11 introduces chlorine gas into chlorine inlet pipe 13. A detection regulator 12 is installed on the surface of chlorine inlet pipe 13 to detect and control the chlorine content concentration, etc. The chlorine gas passes through... Chlorine inlet pipe 13 is introduced into reaction tank 2, where chlorine gas is used to disinfect water. At the same time, the chlorine gas reacts with water to produce hydrochloric acid and hypochlorous acid. Motor 221 drives rotating rod 222 to rotate, causing the mixing component on the surface of rotating rod 222 to press down, pressing down the lighter and incompletely reacted chlorine gas and compressing spring 227. After the mixing component moves down to a certain depth, motor 221 locks rotating rod 222. Under the action of the spring 227's rebound force, the mixing component is pushed up. Blade 225 rotates downward on the surface of connecting rod 224. During the upward movement, movable ring 223 rotates on the surface of rotating rod 222 with threaded grooves. The rotation of blade 225 causes water to generate a rotating flow.

[0064] The clutch assembly engages to open the baffle 23, connecting the disinfection chamber 22 and the reaction chamber 24. Water, driven by the blades 225 to generate a rotating flow, is guided into the reaction chamber 24, and the baffle 23 is promptly closed to prevent backflow. The inlet pipe 21 then repeats the water inlet disinfection operation. Meanwhile, the water source mixed with chlorine entering the reaction chamber 24 is controlled at a specific temperature by the temperature-controlled photosynthetic unit 242 for reaction. Hypochlorous acid exists only in solution, is unstable, and easily decomposes, releasing oxygen. When chlorine water is exposed to sunlight or at a certain temperature, hypochlorous acid decomposes rapidly to form hydrogen chloride solution and oxygen. After the hypochlorous acid reaction is complete, the gas is released through cylinder 28. The output pushes the extrusion plate 26 towards the reaction chamber 24, thereby extruding the water in the reaction chamber 24. This causes the water in the reaction chamber 24 to pass through the through-holes into the activated carbon filter element 261 for filtration. The activated carbon filter element 261 uses highly adsorbent activated carbon fiber (ACF) as its main component. The ACF has a BET specific surface area of ​​1500–3000 m² / g, adsorbing chlorine or residual chlorine with a rate exceeding 95–99%. When the adsorbed chlorine reaches saturation, it forms a highly effective chlorine membrane for efficient sterilization and disinfection. Chlorine ions / molecules escaping from the chlorine membrane readily react with hydrolysis, releasing oxygen during temperature-controlled photosynthesis to form a stable HCl-containing solution. In this process, after passing through the activated carbon filter element 261, residual chlorine in the water is filtered, further improving the chlorine filtration effect. During the process of squeezing the water by the extrusion plate 26, the excess oxygen generated in step S4 above enters the gas chamber 266 through the connecting pipe and then enters the gas outlet pipe 264, and is discharged through the gas hole. At this time, hydrogen is introduced through the hydrogen supply control valve 272, which is connected to an external hydrogen supply device. The hydrogen enters the activated carbon filter element 261 through the hydrogen filling pipe 27, reacts with the oxygen discharged from the gas hole, and generates water and activated water molecules, further controlling the purity of hydrogen chloride in the water to achieve the required controllable pH value. The hydrogen chloride solution, after being filtered through activated carbon filter element 261, is discharged through outlet pipe 212. The end of outlet pipe 212 is connected to pressure regulating storage tank 4. Pressure regulating storage tank 4 is equipped with a detection and monitoring device 41, which is used to detect water temperature, concentration, residual chlorine, pH adjustment gradient (6.9-0.9), TDS, etc. A controllable display screen can be installed on the surface of pressure regulating storage tank 4 and connected to detection and monitoring device 41 to display parameters. Subsequently, the HCl solution is output through outlet pipe 43 by positive and negative pressure controller 42 to control the output water pressure, ensuring the safety and quality of the output purified HCl solution.

[0065] This embodiment also discloses a purification method for converting chlorine-containing aqueous solution into hydrogen chloride through adsorption, comprising the following steps:

[0066] S1. A valve is connected to the municipal tap water, surface water, or groundwater input. A booster pump is installed after the A valve. A pre-backwash filter is installed after the booster pump. A negative charge layer alloy catalyst scale inhibitor is installed after the filter. An ultrafiltration membrane purifier is installed after the scale inhibitor. A control valve B is installed after the ultrafiltration membrane purifier. The reaction tank is connected after the control valve B.

[0067] S2. The C valve, which introduces chlorine gas from the external salt electrolysis chlorine generator, has a detection regulator and a mixing device connected to the reaction tank at its rear end. The C valve is the inlet for the water purifier to input chlorine gas into the detection regulator. The detection regulator controls the chlorine gas flow rate and concentration. The chlorine gas introduced through the C valve mixes with the purified water introduced through the B valve to disinfect the water, facilitating the full conversion of the water and chlorine gas to generate HCl and HClO.

[0068] S3. The chlorine-water mixture after step 2 is introduced into the high-adsorption chlorine chamber. The high-adsorption chlorine integrated chamber is equipped with a D valve on its side, which is connected to an external hydrogen production device. The hydrogen input enhances the reaction between hydrogen and chlorine to form the required pH value. The high-adsorption chlorine integrated device is mainly composed of high-adsorption activated carbon fiber (ACF), supplemented with PP cotton layer and maifan stone. Through the BET specific surface area of ​​ACF of 1500-3000 (㎡ / g), the adsorption of chlorine or residual chlorine reaches 60-97%. The residual chlorine in the water is effectively filtered and converted by the activated carbon fiber filter element, further eliminating residual chlorine.

[0069] S4. The adsorbed chlorine reaches a saturation concentration, forming a special chlorine membrane (highly efficient sterilization and disinfection). Chlorine ions / molecules that overflow from the chlorine membrane easily undergo hydrolysis in water, releasing oxygen under the action of a temperature-controlled photosynthetic device to form a stable HCl-containing solution. This solution is then connected to a positive and negative pressure regulating storage tank. The parameters of the HCl-containing solution are monitored and controlled by a detection and monitoring controller. A controllable display screen is installed on the surface of the detection and monitoring controller, displaying parameters such as water temperature, concentration, residual chlorine, pH value (adjustment gradient 6.9~0.9), and TDS, ensuring the safety and quality of the output purified HCl-containing solution.

[0070] S5, outputs aqueous solution containing HCl.

[0071] This invention effectively improves the purification purity of drinking water containing HCl by a pH gradient of 6.9 to 0.9. It is safe, non-toxic, and has no side effects. HCl is the main component of human stomach acid with a pH of 0.9 to 1.5. It can effectively promote food digestion, resist microbial infection, dissolve and separate calcium scale in the body, ensure unobstructed blood vessels, protect the mucous membranes of the blood vessels, and convert solid scale into liquid calcium chloride that is soluble in water and blood, thus supplementing and enhancing the body's calcium levels.
