Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chlorine dioxide production, in particular to a chlorine dioxide multi-point positive pressure adding system. BACKGROUND

[0002] The chlorine dioxide generator is an environmental protection type chemical chlorine dioxide multi-stage generator, which can generate chlorine dioxide through chemical reaction under negative pressure condition. It is usually composed of a feeding system, a reaction system, a heating system, a safety system, an automatic control system, a residual liquid separation system and an absorption adding system, etc. Sodium acid, sulfuric acid or composite sodium chlorate, composite sodium bisulfate, etc. are used as raw materials to generate chlorine dioxide in the reactor through chemical reaction. Chlorine dioxide has high efficiency, wide spectrum, no residue, no by-product disinfection capacity, and strong oxidation capacity such as COD reduction, iron and manganese removal, decolorization, deodorization and odor removal. Therefore, the chlorine dioxide generator is widely used in water treatment, food processing, medical disinfection and other fields, and is an important tool to improve public health level and ensure food safety.

[0003] In many water treatment, disinfection and sterilization fields, chlorine dioxide is widely used due to its high efficiency, wide spectrum of bactericidal performance and relatively low toxicity.

[0004] The existing chlorine dioxide generator is prepared on site and operated under negative pressure, which is easily affected by factors such as power water pressure and pipeline resistance.

The conditions of the disinfectant adding point in the water treatment plant are required more, and the adding point height difference of more than 5 meters basically cannot be normally added. The adding distance or adding resistance may not meet the normal disinfection operation, which causes the control system to fail to obtain stable liquid level signals, and further fail to accurately control the start-stop and frequency of the metering pump, finally resulting in unstable chlorine dioxide adding amount, affecting the disinfection effect, and even causing secondary pollution due to excessive adding.

[0025] With reference to Figures 1-7 In a preferred implementation form, one side of the bottom sweeping plate 406 is fixedly connected with two fixed blocks three 427, the inside of the two fixed blocks three 427 are both connected with a resisting rod 429 through a bearing, one end of the two resisting rods 429 is movably connected with the same cleaning sweeping plate 430, one side of the two resisting rods 429 are both fixedly connected with a squeezing spring 428, and one side of the squeezing spring 428 is fixedly connected with one side of the bottom sweeping plate 406.

[0027] Specifically, when the disinfectant generated by the chlorine dioxide generator body 1 enters the top cover 401 at the top of the buffer tank 3 through the water guide pipe 6 at a certain pressure and flow rate, the liquid flow is first introduced into the flow guide cover 402, and the high-speed liquid flow directly impacts and drives multiple turbines 417 to rotate. This process cleverly converts the linear kinetic energy of the fluid into the rotational mechanical energy of the turbine 417, achieving energy recovery and reuse, providing self-driving power for the entire stirring system without external power supply, saving energy and protecting the environment. The liquid flow emitted from the outlet of the flow guide cover 402 still has a high speed and a rotating tendency, and if it directly enters the tank body, it will cause severe disturbance. The liquid flow first hits the multiple vortex suppression guide frames 422 distributed circumferentially. These guide frames are installed through fixed block one 421 and fixed block two 423 and can be self-adaptively deflected within a certain angle. With the damping action of the telescopic spring 426, they can effectively deflect and disperse the liquid flow, greatly weakening the core vortex intensity and impact energy of the liquid flow. After preliminary adjustment by the vortex suppression guide frame 422, the liquid flow continues to flow downward to the homogenizing orifice plate 409 fixed inside the top cover 401. The diffusion holes 410 densely opened on the homogenizing orifice plate 409 further divide and break the liquid flow into countless small, disordered micro-flow beams. This process completely disperses the remaining small-scale vortices, making the flow rate distribution of the liquid flow more flat and uniform. The limiting plates 411 arranged in a diffusing manner on the homogenizing orifice plate 409 play a guiding and supporting role, ensuring stable flow pattern. Finally, the liquid flow spreads over the entire turbulence disc 407 in a very stable state, maximizing the elimination of impact and disturbance on the lower main liquid surface. The rotating main shaft 403 drives the turbulence disc 407 fixed thereon to rotate synchronously. The multiple turbulence grooves 408 asymmetrically arranged on the turbulence disc 407 can convert the vertical disturbance kinetic energy that may remain after falling through the homogenizing orifice plate 409 into 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 main shaft 403 drives the stirring frame 404 located at the lower part thereof and the stirring arm 405 fixedly connected thereto to rotate powerfully. The stirring arm 405 stirs the liquid in the lower part of the buffer tank 3, ensuring that the newly entered disinfectant solution with a higher concentration is quickly and uniformly mixed with the existing solution in the tank, effectively avoiding the problem of subsequent dosage accuracy reduction caused by concentration stratification, and ensuring the consistency of the concentration of each batch of added solution. During the entire stirring process, the bottom sweep plate 406 fixed to the end of the main shaft 403 rotates closely along the contour of the tank bottom of the buffer tank 3. Its lower surface is movably connected with the cleaning sweep plate 430 through the fixed block three 427, the abutting rod 429, and the extrusion spring 428. Under the action of the extrusion spring 428, the cleaning sweep plate 430 is always elastically abutted against the tank bottom wall. This design can continuously scrape the boundary layer liquid most prone to deposition at the bottom of the buffer tank 3, effectively preventing solid impurities (such as reaction byproducts) or high-concentration solution from stagnating and scaling in the dead corners, maintaining the cleanliness of the tank, and further ensuring the long-term stable operation of the solution homogenization and dosing system.

[0028] In a specific application scenario, the disturbance prevention module 4 creates an extremely stable fluid environment in the buffer tank 3 through a series of coherent and efficient actions such as "kinetic energy recovery self-driving, eddy current suppression and breaking, horizontal cyclone conversion, forced stirring homogenization, and bottom active cleaning", which provides ideal measurement conditions for liquid level detection, enabling it to obtain stable and true liquid level signals, thereby laying a solid foundation for precise control of the start and stop and frequency of the dosing pump group 12, and ultimately ensuring the high stability and precision of the chlorine dioxide dosage.

[0032] Referring to Figure 1 , Figure 2 and Figure 3 , in a preferred embodiment, the buffer tank 3 is provided with a base 11, and the top of the base 11 is provided with two groups of dosing pump groups 12, the inner wall of the buffer tank 3 is communicated with a transversely arranged water distribution pipe 13, and the two ends of the water distribution pipe 13 away from the buffer tank 3 are respectively communicated with the water inlets of the two groups of dosing pump groups 12, the water outlets of the dosing pump groups 12 are communicated with a water delivery pipe 16, and one end of the water delivery pipe 16 away from the dosing pump groups 12 is provided with a dosing hopper 17, and the outside of the water delivery pipe 16 is respectively provided with a second flow monitor 14 and a blockage detector 15.

[0033] Specifically, during the operation of the buffer tank 3, trace amounts of chlorine dioxide gas and other gases are released, which are introduced into the bottom of the tower body one 502 through the gas guide pipe 505, and the gas rises due to the installation of the air passage plate 513 inside the tower body one 502, then the gas enters the tower body two 504 and passes through the two-stage adsorption layer 512 installed therein in turn, and the harmful gas components are effectively adsorbed or neutralized, and the purified gas removes the water mist that may be entrained through the demisting receiver 511, and is finally safely discharged through the purification exhaust pipe 510, which ensures the air quality of the working environment and meets the environmental protection requirements. The universal motor 507 drives the belt 508 to drive the intermittent adjustment panel 514 to rotate slowly, and the equidistantly arranged air passage 515 on the intermittent adjustment panel 514 is periodically aligned with the air passage of the air passage plate 513, so that the gas is uniformly discharged onto the adsorption layer 512, increasing the purification effect. The liquid level detector 501 is installed on the top cover 401 for real-time and continuous monitoring of the liquid level height in the buffer tank 3, and transmits accurate electrical signals to the control system as the main basis for automatically controlling the dosing pump group 12. The liquid level monitoring is simultaneously accompanied by the floating liquid level ball 517 rising and falling with the liquid level, driving the scale cylinder 516 fixedly connected thereto to slide up and down in the round sliding hole of the top cover 401. The operator can directly read the liquid level in the tank by observing the position of the scale on the scale cylinder 516, which is convenient for safety inspection and emergency judgment. This "double insurance" design effectively avoids the system misjudgment caused by the failure of a single sensor, ensuring the absolute safety of the system operation.

[0034] Working principle: when the disinfectant produced by the chlorine dioxide generator body 1 through the water pipe 6 into the buffer tank 3 top cover 401 with a certain pressure and flow rate, the liquid flow is first introduced into the flow guide cover 402, high-speed liquid flow directly impact and drive multiple turbine 417 rotation, this process cleverly convert the linear kinetic energy of fluid into the rotating mechanical energy of turbine 417, realize the energy recycling and reuse, provide the whole stirring system with self driving force without external power supply, energy saving and environmental protection, the liquid flow from the outlet of the flow guide cover 402 still has high speed and rotation tendency, if directly into the tank, will cause severe disturbance, the liquid flow first impact on the circumferentially distributed multiple vortex suppression guide frame 422, these guide frame is installed through fixed block one 421 and fixed block two 423, and can be self adaptive deflection within a certain angle, cooperate with the damping effect of telescopic spring 426, can effectively deflect and disperse the liquid flow, greatly weaken the core vortex intensity and impact energy of the liquid flow, after the preliminary setting of the liquid flow by the vortex suppression guide frame 422, continue to flow downward to the homogenizing orifice plate 409 fixed in the top cover 401, the diffusion hole 410 densely arranged on the homogenizing orifice plate 409 further divide and break the liquid flow into countless small, disordered micro flow, this process completely scatter the remaining small scale vortex, make the flow velocity distribution of the liquid flow more flat and uniform, the limiting plate 411 arranged in a diffusion manner on the homogenizing orifice plate 409 play a guiding and supporting role, ensure the stability of the flow pattern, finally, the liquid flow diffuses to the whole turbulence disc 407 in a very stable state, the maximum degree eliminates the impact and disturbance to the lower main liquid surface, the driving shaft 403 drives the turbulence disc 407 fixed thereon to rotate synchronously, the multiple turbulence grooves 408 asymmetrically arranged on the turbulence disc 407 can convert the vertical direction disturbance kinetic energy of the liquid falling after the homogenizing orifice plate 409 into small scale, ordered horizontal rotation flow, this horizontal flow has little effect on the stability of the whole liquid surface, at the same time, the driving shaft 403 drives the stirring frame 404 and the stirring arm 405 fixedly connected thereon to rotate powerfully, the stirring arm 405 stirs the liquid in the lower part of the buffer tank 3, ensure the new incoming liquid with higher concentration and the existing solution in the tank to mix quickly and uniformly, effectively avoid the problem of subsequent dosage accuracy decline caused by concentration stratification, ensure the consistency of the concentration of each batch of added solution, in the whole stirring process, the bottom sweep plate 406 fixed to the end of the driving shaft 403 rotates closely to the bottom contour of the buffer tank 3, the lower surface of the bottom sweep plate 406 is movably connected with the cleaning sweep plate 430 through the fixed block three 427, the abutting rod 429 and the extrusion spring 428, under the action of the extrusion spring 428, the cleaning sweep plate 430 always elastically abuts against the tank bottom wall, this design can continuously scrape the boundary layer liquid which is most prone to form on the bottom of the buffer tank 3, the buffer tank 3 in the running process reaction escapes trace amount of chlorine dioxide gas, these gases are introduced into the tower body one 502 bottom through the air guide pipe 505,The air venting plate 513 installed inside the tower body 1 502 makes the gas rise, then the gas enters the tower body 2 504, sequentially 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 51 1 to remove the possible entrained water mist, and finally is safely discharged through the purified exhaust pipe 510, the process ensures the air quality of the working environment and meets the environmental protection requirements. The general motor 507 drives the belt 508 to drive the intermittent adjusting panel 514 to rotate slowly, the air venting passages 515 equally and separately provided on the intermittent adjusting panel 514 are periodically aligned with the air venting openings of the air venting plate 513, so that the gas is uniformly discharged to the adsorption layer 512, the purification effect is increased, the liquid level detector 501 is installed on the top cover 401 and is used for monitoring the liquid level height in the buffer tank 3 in real time and continuously, and the accurate electric signal is transmitted to the control system as the main basis for automatically controlling the dosing pump set 12. The liquid level monitoring simultaneously floats the liquid level ball 517 which drives the fixed scale cylinder 516 to slide up and down in the smooth hole of the top cover 401, the operator can directly read the liquid level in the tank by observing the position of the scale on the scale cylinder 516, and safety inspection and emergency judgment are facilitated.
