Description

Technical Field

[0001] This invention relates to the field of chlorine dioxide production technology, and in particular to a multi-point positive pressure dosing system for chlorine dioxide. Background Technology

[0002] A chlorine dioxide generator is an environmentally friendly, multi-stage chemical chlorine dioxide generator that produces chlorine dioxide through a chemical reaction under negative pressure. It typically consists of a feeding system, reaction system, heating system, safety system, automatic control system, residual liquid separation system, and absorption and dosing system. Using sodium chlorate, sulfuric acid, or complex sodium chlorate and complex sodium bisulfate as raw materials, a chemical reaction occurs within the reactor to generate chlorine dioxide. Chlorine dioxide possesses highly efficient, broad-spectrum, residue-free, and byproduct-free disinfection capabilities, as well as strong oxidizing abilities such as COD reduction, iron and manganese removal, decolorization, deodorization, and odor removal. Therefore, chlorine dioxide generators are widely used in water treatment, food processing, medical disinfection, and many other fields, serving as an important tool for improving public health and ensuring food safety.

[0003] Chlorine dioxide is widely used in many fields such as water treatment and disinfection due to its high efficiency, broad spectrum bactericidal properties and relatively low toxicity. As a key device for producing chlorine dioxide solution, the stability and accuracy of the dosing system of the chlorine dioxide generator directly affect the treatment effect.

[0004] Existing chlorine dioxide generators are prepared on-site and operate under negative pressure, making them susceptible to factors such as dynamic water pressure and pipeline resistance. Furthermore, the low outlet pressure after the chlorine dioxide disinfectant is drawn and mixed by the water jet injector severely limits the height, location, and quantity of dosing points. This places numerous demands on the conditions of disinfectant dosing points within the water treatment plant; dosing is practically impossible with elevation differences exceeding 5 meters. Even slight differences in dosing distance or resistance can prevent normal disinfection operation, causing the control system to be unable to obtain stable liquid level signals. Consequently, it cannot accurately control the start, stop, and frequency of the metering pump, ultimately leading to unstable chlorine dioxide dosage, affecting disinfection effectiveness, and potentially causing secondary pollution due to overdosing. Summary of the Invention

A baffle plate 407 is fixedly connected to the outside of the drive shaft 403. The baffle plate 407 is located below the homogenizing orifice plate 409.

Stirring arms 405 are fixedly connected at equal intervals to the outside of the stirring frame 404. A bottom sweeping plate 406 is fixedly connected to one end of the drive shaft 403 facing the bottom of the buffer tank 3.

[0035] Reference Figures 1-7 In a preferred embodiment, two fixing blocks 427 are fixedly connected to one side of the bottom sweeping plate 406, and the interior of each fixing block 427 is connected to a push rod 429 via a bearing. One end of each push rod 429 is movably connected to the same cleaning sweeping plate 430. A compression spring 428 is fixedly connected to one side of each push rod 429, and one side of the compression spring 428 is fixedly connected to one side of the bottom sweeping plate 406.

[0036] Specifically, when the disinfectant generated by the chlorine dioxide generator body 1 enters the top cover 401 of the buffer tank 3 through the water guide pipe 6 at a certain pressure and flow rate, the liquid flow is first guided into the guide shroud 402. The high-speed liquid flow directly impacts and drives multiple turbines 417 to rotate. This process cleverly and efficiently converts the linear kinetic energy of the fluid into the rotational mechanical energy of the turbines 417, realizing energy recovery and reuse. It provides the entire stirring system with self-driving power without external power supply, which is energy-saving and environmentally friendly. The liquid flow ejected from the outlet of the guide shroud 402 still has a high speed and rotational tendency. If it directly enters the tank, it will cause violent disturbance. The liquid flow first hits multiple vortex suppression guide frames 422 distributed in a circle. These guide frames are fixed by a fixed block 421 and a fixed The second block 423 is installed and can adaptively deflect within a certain angle. Combined with the damping effect of the telescopic spring 426, it can effectively deflect and disperse the liquid flow, greatly weakening the core vortex intensity and impact energy. After initial adjustment by the vortex suppression guide frame 422, the liquid flow continues downwards towards the homogeneous perforated plate 409 fixed inside the top cover 401. The densely packed diffusion holes 410 on the homogeneous perforated plate 409 further divide and break the liquid flow into countless small, disordered micro-streams. This process completely disperses the remaining small- and medium-scale vortices, making the flow velocity distribution of the liquid flow flatter and more uniform. The diffusion-type limiting plates 411 on the homogeneous perforated plate 409 play a guiding and supporting role, ensuring flow pattern stability. Finally, the liquid flow is in an extremely stable state. The turbulence diffuses across the entire baffle plate 407, minimizing the impact and disturbance to the main liquid surface below. The rotating drive shaft 403 drives the baffle plate 407, which is fixed to it, to rotate synchronously. The multiple asymmetrically arranged baffle grooves 408 on the baffle plate 407 can convert any residual vertical disturbance kinetic energy that may have fallen after passing through the homogenizing orifice plate 409 into a small-scale, orderly horizontal rotating flow. This horizontal flow has minimal impact on the overall stability of the liquid surface. At the same time, the drive shaft 403 drives the stirring frame 404 located in its lower part and the stirring arms 405 fixedly connected at equal intervals to rotate powerfully. The stirring arms 405 agitate the liquid in the lower part of the buffer tank 3, ensuring that the newly entered disinfectant, which may have a higher concentration, is quickly and uniformly mixed with the existing solution in the tank. This design effectively avoids the problem of decreased dosing accuracy caused by concentration stratification, ensuring the consistency of solution concentration in each batch. During the entire stirring process, the bottom sweeping plate 406, fixed to the end of the drive shaft 403, rotates close to the bottom contour of the buffer tank 3. Its lower surface is movably connected to the cleaning sweeping plate 430 through the fixing block 427, the push rod 429, and the compression spring 428. Under the action of the compression spring 428, the cleaning sweeping plate 430 always elastically abuts against the bottom wall of the tank. This design can continuously scrape the boundary layer liquid at the bottom of the buffer tank 3, which is most prone to precipitation, effectively preventing solid impurities (such as reaction byproducts) or high-concentration solutions from lingering and scaling in dead corners. This not only keeps the tank clean but also further ensures solution homogenization and the long-term stable operation of the dosing system.

[0037] In specific application scenarios, the disturbance prevention module 4 creates an extremely stable fluid environment inside the buffer tank 3 through a series of coherent and efficient actions, including "kinetic energy recovery self-drive, eddy current suppression and breaking, horizontal vortex conversion, forced stirring and homogenization, and active bottom cleaning". This provides ideal measurement conditions for liquid level detection, enabling it to obtain stable and accurate liquid level signals. This lays a solid foundation for accurately controlling the start-up, shutdown, and frequency of the dosing pump group 12, ultimately ensuring the high stability and accuracy of chlorine dioxide dosing.

[0038] Reference Figure 1 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, a dosing auxiliary module 5 is provided on the outside of the buffer tank 3, and the dosing auxiliary module 5 includes an air guide pipe 505.

The same second tower body 504 is fixedly connected to one side of the two U-shaped support rods 503. Two adsorption layers 512 are installed inside the second tower body 504. A ventilation plate 513 is installed inside the first tower body 502.

[0039] Reference Figure 1 , Figure 8 , Figure 9 and Figure 10 In a preferred embodiment, the interiors of tower body 1 502 and tower body 2 504 are connected by bearings to the same intermittent adjustment panel 514, and ventilation channels 515 are provided at equal intervals on one side of the intermittent adjustment panel 514.

An installation port is provided on one side of the top cover 401. A liquid level detector 501 is provided inside the installation port. A floating liquid level ball 517 is slidably connected to the outside of the liquid level detector 501. Two smooth holes are provided on one side of the top cover 401. A graduated cylinder 516 is slidably connected inside each of the two smooth holes. One end of the graduated cylinder 516 is fixedly connected to one side of the floating liquid level ball 517.

[0041] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a base 11 is provided on one side of the buffer tank 3, and two sets of dosing pump sets 12 are provided on the top of the base 11. A horizontally arranged water distribution pipe 13 is connected to the inner wall of the buffer tank 3, and the two ends of the water distribution pipe 13 away from the buffer tank 3 are respectively connected to the inlets of the two sets of dosing pump sets 12. A water supply pipe 16 is connected to the outlet of the dosing pump set 12. A dosing hopper 17 is provided at the end of the water supply pipe 16 away from the dosing pump set 12. A second flow monitor 14 and a blockage detector 15 are respectively provided on the outside of the water supply pipe 16.

[0042] Specifically, during operation, buffer tank 3 releases trace amounts of gases such as chlorine dioxide. These gases are introduced into the bottom of tower body 502 through gas guide pipe 505. The ventilation plate 513 installed inside tower body 502 causes the gas to rise. Subsequently, the gas enters tower body 504 and passes through the two-stage adsorption layer 512 installed inside. The harmful gas components are effectively adsorbed or neutralized. The purified gas passes through the demisting receiver 511 to remove any water mist that may be entrained. Finally, it is safely discharged through the purified exhaust pipe 510. This process ensures the air quality of the working environment and meets environmental protection requirements. Driven by a general-purpose motor 507 and belt 508, the intermittent adjustment panel 514 rotates slowly. The equidistant ventilation channels 515 on the intermittent adjustment panel 514 periodically align with the ventilation ports of the ventilation plate 513, ensuring uniform gas discharge onto the adsorption layer 512 and enhancing the purification effect. A level detector 501, mounted on the top cover 401, continuously monitors the liquid level in the buffer tank 3 in real time and transmits precise electrical signals to the control system, serving as the primary basis for automatically controlling the dosing pump group 12. Simultaneously, a floating level ball 517 rises and falls with the liquid level, causing a fixed graduated cylinder 516 to slide up and down within a smooth hole in the top cover 401. Operators can directly read the liquid level in the tank by observing the position of the graduations on the graduated cylinder 516, facilitating safety inspections and emergency assessments. This "double insurance" design effectively prevents system misjudgments due to a single sensor failure, ensuring absolute system safety.

[0043] Working principle: When the disinfectant generated by the chlorine dioxide generator body 1 enters the top cover 401 of the buffer tank 3 through the water guide pipe 6 at a certain pressure and flow rate, the liquid flow is first guided into the guide shroud 402. The high-speed liquid flow directly impacts and drives multiple turbines 417 to rotate. This process cleverly and efficiently converts the linear kinetic energy of the fluid into the rotational mechanical energy of the turbines 417, realizing energy recovery and reuse. It provides the entire stirring system with self-driving force without external power supply, which is energy-saving and environmentally friendly. The liquid flow ejected from the outlet of the guide shroud 402 still has a high speed and rotational tendency. If it directly enters the tank, it will cause violent disturbance. The liquid flow first hits multiple vortex suppression guide frames 422 distributed in a circle. These guide frames are fixed by a fixed block 42. 1. The fixed block 423 is installed and can adaptively deflect within a certain angle. With the damping effect of the telescopic spring 426, it can effectively deflect and disperse the liquid flow, greatly weakening the core vortex intensity and impact energy of the liquid flow. After the liquid flow is initially regulated by the vortex suppression guide frame 422, it continues to flow downwards to the homogeneous perforated plate 409 fixed inside the top cover 401. The densely distributed diffusion holes 410 on the homogeneous perforated plate 409 further divide and break the liquid flow into countless small and disordered micro-flow streams. This process completely disperses the remaining small and medium-scale vortices, making the flow velocity distribution of the liquid flow flatter and more uniform. The limiting plates 411 arranged in a diffusion pattern on the homogeneous perforated plate 409 play a guiding and supporting role, ensuring the stability of the flow pattern. Finally, the liquid flow... The fluid diffuses smoothly across the entire baffle plate 407, minimizing impact and disturbance to the main liquid surface below. The rotating drive shaft 403 drives the baffle plate 407, fixed to it, to rotate synchronously. Multiple asymmetrically arranged baffle grooves 408 on the baffle plate 407 convert any residual vertical disturbance energy that may have fallen after passing through the homogenizing orifice plate 409 into a small-scale, ordered horizontal rotating flow. This horizontal flow has minimal impact on the overall stability of the liquid surface. Simultaneously, the drive shaft 403 drives the stirring frame 404 located in its lower part and its equidistantly fixed stirring arms 405 to rotate powerfully. The stirring arms 405 agitate the liquid in the lower part of the buffer tank 3, ensuring that the newly introduced, potentially highly concentrated disinfectant is neutralized by the existing liquid in the tank. The solution is rapidly and uniformly mixed, effectively avoiding the problem of decreased subsequent dosing accuracy caused by concentration stratification, and ensuring the consistency of the concentration of each batch of added solution. During the entire stirring process, the bottom sweeping plate 406, fixed to the end of the drive shaft 403, rotates close to the bottom contour of the buffer tank 3. Its lower surface is movably connected to the cleaning sweeping plate 430 through the fixing block 427, the push rod 429, and the compression spring 428. Under the action of the compression spring 428, the cleaning sweeping plate 430 always elastically abuts against the bottom wall of the tank. This design can continuously scrape the boundary layer liquid at the bottom of the buffer tank 3, where precipitation is most likely to form. During the operation of the buffer tank 3, trace amounts of gases such as chlorine dioxide are released. These gases are introduced into the bottom of the tower body 502 through the gas guide pipe 505.The ventilation plate 513 installed inside tower body 502 causes the gas to rise. The gas then enters tower body 504 and passes through two-stage adsorption layers 512 installed inside. Harmful gas components are effectively adsorbed or neutralized. The purified gas passes through a demisting receiver 511 to remove any entrained water mist, and is finally safely discharged through a purified exhaust pipe 510. This process ensures the air quality of the working environment and meets environmental protection requirements. A general-purpose motor 507 drives a belt 508, which in turn slowly rotates an intermittent adjustment panel 514. The equally spaced ventilation channels 515 on the intermittent adjustment panel 514 periodically align with the ventilation ports of the ventilation plate 513, ensuring that the gas is evenly discharged onto the adsorption layers 512, increasing the purification effect. A liquid level detector 501 is installed on the top cover 401 to continuously monitor the liquid level in the buffer tank 3 in real time and transmits a precise electrical signal to the control system, serving as the primary basis for automatically controlling the dosing pump group 12. Simultaneously, the floating level gauge 517 rises and falls with the liquid level, causing the fixed graduated cylinder 516 to slide up and down within the smooth hole of the top cover 401. Operators can directly read the liquid level in the tank by observing the position of the scale on the graduated cylinder 516, facilitating safety inspections and emergency assessments.
