Description

Technical Field

[0001] The invention belongs to the technical field of waste liquid neutralization treatment, and more specifically, particularly relates to a device for neutralizing butanedisulfonic acid waste liquid. Background Art

[0002] Succinic acid is an organic compound, and the composition of its waste liquid is usually complex. It may contain incompletely reacted succinic acid, by-products generated during the reaction, solvents used, other possible residual chemical reagents, and decomposition products generated under the reaction conditions. This waste liquid has certain chemical hazards. If it is directly discharged without proper treatment, it may pollute the environment and affect the balance of soil, water and ecosystems. At the same time, some of its components may also pose a potential threat to human health.

[0003] However, the existing butanedisulfonic acid waste liquid neutralization treatment device still has the following shortcomings when used:

[0004] 1. When adding neutralizers, existing equipment mostly adds them by direct pouring or simple stirring and mixing, which makes it difficult to achieve uniform and sufficient contact between the neutralizer and the waste liquid, resulting in incomplete neutralization reaction. Harmful substances may still remain in the treated waste liquid, which cannot meet the emission standards;

[0005] 2. The filtration device of existing equipment often adopts a fixed filter screen structure. Impurities in the waste liquid tend to accumulate quickly on the filter screen surface, causing the filter screen pores to be quickly blocked. This not only reduces the filtration speed, but also requires frequent shutdown to replace or clean the filter screen, increasing labor intensity and equipment maintenance costs.

[0016] Preferably, stirring blades are evenly and equidistantly installed on the side wall of the inner cylinder, an inner groove is opened inside each of the stirring blades, and a pH sensor is installed inside each of the inner grooves.

[0017] Preferably, each stirring blade has notches at both ends, the two limiting rings are respectively arranged in the two notches, the inner wall of the processing cylinder has limiting grooves symmetrically arranged, and the blocking rod is slidably installed in the two limiting grooves.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, a driving motor, a rotating shaft, a circular ring, a first annular filter screen, a first drainage plate and a cleaning rod are provided. The driving motor drives the rotating shaft to rotate accordingly. The rotation of the rotating shaft drives the first drainage plate, the first annular filter screen and the circular ring to rotate accordingly. At this time, centrifugal force is generated, and the butanedisulfonic acid waste liquid is thrown onto the first annular filter screen. Then, after being filtered by the first annular filter screen, the waste liquid is floated in a mist-like state between the inner wall of the treatment cylinder and the first annular filter screen. By designing the first annular filter screen into an annular and centrifugal filtering structure, the butanedisulfonic acid waste liquid will not be blocked during filtration. At the same time, when the first annular filter screen and the first drainage plate are rotating, the two will contact the cleaning rod. At this time, the cleaning rod will scrape the two, and the impurities attached to the filter surface and the drainage component can be removed in time, thereby further enhancing the anti-blocking effect, ensuring the continuous and stable progress of the filtration process, and reducing the downtime and maintenance time and cost caused by blockage.

[0020] In the present invention, a treatment barrel, a control panel, a delivery pump, a delivery pipe, a liquid storage ring and an atomizing net are provided, and two delivery pumps can be controlled to start through the control panel, and the two delivery pumps will extract the neutralizer in the liquid storage tank, and then inject it into the liquid storage ring through the delivery pipe, and then spray it out after atomization through the atomizing net. Since the atomizing net is also designed to be annular, the sprayed neutralizer spray will be combined with the spray of the butanedisulfonic acid waste liquid and condensed on the inner wall of the treatment barrel to complete the initial mixing of the two. The atomized neutralizer and waste liquid have extremely high surface energy and activity, and the molecules between them can quickly penetrate and act on each other. The tiny size of the mist droplets and the large amount of interface area accelerate the diffusion of the substance and the rate of the chemical reaction. When the two mist liquids collide and combine with each other, the neutralization reaction can be triggered almost instantly, which greatly shortens the induction period and the overall time of the reaction, and significantly improves the efficiency of the entire neutralization treatment.

[0021] In the present invention, by providing a treatment cylinder, a rotating shaft, a baffle, a second drainage disk, a spiral feed trough, an inner cylinder, a suction port, an inner disk, a spring and a wedge-shaped strip, the neutralizer spray will combine with the butanedisulfonic acid waste liquid spray and condense on the treatment cylinder to form water droplets, the accumulation of water droplets into a water flow will fall on the second drainage disk, and then flow through the second drainage disk to the inside of the spiral feed trough, the mixed liquid will rotate and accelerate inside the spiral feed trough and then fall into the treatment cylinder, at this time, the mixed liquid of the two will be mixed again, and then the mixed liquid will enter the inner cylinder under the drainage action of the rotating shaft, at this time, the rotating shaft will drive the inner cylinder to rotate when it rotates, and when the inner cylinder rotates, the wedge-shaped strip will contact the baffle, this When the second drain plate is pulled back, the baffle rod will be limited by the second drainage plate and cannot move. The two wedge-shaped bars will move downward under the extrusion force. At this time, the two wedge-shaped bars will drive the inner plate to move downward inside the inner cylinder. The inner plate will drive the spring to compress. When the inner plate is located below the suction port, the mixed liquid will flow out through the suction port. On the contrary, when the wedge-shaped bar is not in contact with the baffle rod, the spring will restore its deformation. At this time, the inner plate will rise inside the inner cylinder, and the space inside the inner cylinder will become larger. At this time, the mixed liquid inside the treatment cylinder will be sucked into the inner cylinder. Under repeated suction, the neutralizer and the butanedisulfonic acid waste liquid can be mixed more fully and evenly, which helps to ensure the complete conduct of the neutralization reaction and improve the treatment effect and quality.

[0022] In the present invention, a treatment cylinder, a drain pipe, an inner cylinder, a stirring blade and a pH sensor are provided. When the inner cylinder rotates, the stirring blade is driven to rotate accordingly. The mixed liquid inside the treatment cylinder is mixed under the rotation of the stirring blade. Compared with the existing equipment, the equipment can greatly improve the reaction efficiency of the neutralizer and the butanedisulfonic acid waste liquid under multiple repeated mixing. At this time, the pH value of the mixed liquid can be measured by the pH sensor, and when the discharge standard is reached, it can be discharged through the drain pipe;

[0023] In the present invention, a fixing ring, a cross frame, a motor mounting frame, a rotating shaft, a threaded ring, a limiting ring, a circular ring, a second drainage plate and a notch are provided. At this time, the bolts on the fixing ring, the cross frame and the motor mounting frame can be removed first, and then the device can be moved up to leave a gap to remove the circular ring and the second drainage plate. Then, the cross frame and the motor mounting frame together with the internal design structure can be taken out together. Then, the threaded ring can be rotated on the rotating shaft, and the threaded ring will drive the limiting ring to slide out of the notch to release the limit, so that the overall loading and unloading of the device is more convenient when in use.

When the equipment needs to be disassembled, the bolts on the fixing ring 13, the cross frame 15 and the motor mounting frame 16 can be removed first, and then the equipment can be moved up to leave a gap to remove the ring 23 and the second drainage plate 41, and then the cross frame 15 and the motor mounting frame 16 can be taken out together with the internal design structure, and then the threaded ring 21 can be rotated on the rotating shaft 18, and the threaded ring 21 will drive the limit ring 22 to slide out of the notch 54 to release the limit, so that the overall loading and unloading of the equipment is more convenient when in use;

[0038] The inner wall of the treatment cylinder 11 is symmetrically provided with limiting grooves 55, and the blocking rod 19 is slidably installed in the two limiting grooves 55. When in use, the butanedisulfonic acid waste liquid can be poured into the ring 23 first, at which time the first drainage plate 25 will drain the butanedisulfonic acid waste liquid to make it diffuse around, and then the control panel 14 is used to control the drive motor 17 to start, and the driving motor 17 will drive the rotating shaft 18 to rotate accordingly, and the rotation of the rotating shaft 18 will drive the first drainage plate 25, the first annular filter 24 and the ring 23 to rotate accordingly, and centrifugal force will be generated at this time, thereby throwing the butanedisulfonic acid waste liquid onto the first annular filter 24, and then after being filtered by the first annular filter 24, it will float in the form of mist between the inner wall of the treatment cylinder 11 and the first annular filter 24, and the first annular filter 24 will be filtered by the first annular filter 24. The net 24 is designed to be annular and centrifugally filtered, so that the succinic acid waste liquid will not be blocked during filtration. At the same time, when the first annular filter screen 24 and the first drainage disk 25 are rotating, the two will contact the cleaning rod 56. At this time, the cleaning rod 56 will scrape the two, and the impurities attached to the filter surface and the drainage component can be removed in time, which further enhances the anti-blocking effect, ensures the continuous and stable progress of the filtration process, and reduces the downtime and maintenance time and cost caused by blockage. At this time, the control panel 14 controls the two delivery pumps 32 to start, and the two delivery pumps 32 will extract the neutralizer in the liquid storage tank 31, and then inject it into the liquid storage ring 35 through the delivery pipe 34, and then atomize it through the atomizing net 36 and spray it out. It is also designed in a ring shape, and the sprayed neutralizer spray will combine with the spray of the succinic acid waste liquid and condense on the inner wall of the treatment tube 11 to complete the initial mixing of the two. The atomized neutralizer and waste liquid have extremely high surface energy and activity, and the molecules between them can quickly penetrate and interact with each other. The tiny size of the mist droplets and the large interface area accelerate the diffusion of substances and the rate of chemical reactions. When the two mist liquids collide and combine with each other, the neutralization reaction can be triggered almost instantly, which greatly shortens the induction period and overall time of the reaction, and significantly improves the efficiency of the entire neutralization treatment. The neutralizer spray will combine with the succinic acid waste liquid spray and condense on the treatment tube 11 to form water droplets. The accumulation of water droplets into a water flow will fall on the second drainage plate 41, and then pass through the second drainage plate 41. The disk 41 flows into the spiral feed trough 43, and the mixed liquid will rotate and accelerate inside the spiral feed trough 43 and then fall into the processing tube 11. At this time, the mixed liquid of the two will be mixed again, and then the mixed liquid will enter the inner tube 44 under the drainage action of the rotating shaft 18. At this time, the rotating shaft 18 will drive the inner tube 44 to rotate when it rotates, and when the inner tube 44 rotates, the wedge-shaped bar 49 will contact the baffle 19. At this time, the baffle 19 will be limited by the second drainage disk 41 and cannot move. The two wedge-shaped bars 49 will move downward due to the extrusion force. At this time, the two wedge-shaped bars 49 will drive the inner disk 46 to move downward inside the inner tube 44, and the inner disk 46 will drive the spring 48 to be compressed. When the inner disk 46 is located below the suction port 45, the mixed liquid will flow out along the suction port 45. Conversely,When the wedge strip 49 is not in contact with the baffle 19, the spring 48 will restore its deformation, and the inner disk 46 will rise inside the inner cylinder 44, and the space inside the inner cylinder 44 will become larger. At this time, the mixed liquid inside the treatment cylinder 11 will be sucked into the inner cylinder 44, and the neutralizer and the butanedisulfonic acid waste liquid can be mixed more fully and evenly under repeated suction, which helps to ensure the complete neutralization reaction and improve the treatment effect and quality. At the same time, when the inner cylinder 44 is rotating, it will drive the stirring blade 51 to rotate accordingly. Under the rotation of the stirring blade 51, the mixed liquid inside the treatment cylinder 11 will also be mixed. Compared with the existing equipment, this equipment can greatly improve the reaction efficiency of the neutralizer and the butanedisulfonic acid waste liquid under multiple repeated mixing. At this time, the pH value of the mixed liquid can be measured by the pH sensor 53, and it can be discharged through the drain pipe 12 when it meets the discharge standard.

[0039] Working principle:

[0040] In the first step, when in use, the butanedisulfonic acid waste liquid can be poured into the ring 23. At this time, the first drainage disc 25 will drain the butanedisulfonic acid waste liquid to make it diffuse around, and then the control panel 14 controls the drive motor 17 to start. Under the action of the drive motor 17, the shaft 18 will be driven to rotate. Under the rotation of the shaft 18, the first drainage disc 25, the first annular filter 24 and the ring 23 will be driven to rotate. At this time, centrifugal force will be generated, and then the butanedisulfonic acid waste liquid will be thrown onto the first annular filter 24, and then after being filtered by the first annular filter 24, it will float in the form of mist. Between the inner wall of the treatment cylinder 11 and the first annular filter screen 24, by designing the first annular filter screen 24 into an annular and centrifugal filtering structure, the butanedisulfonic acid waste liquid will not be blocked during filtering. At the same time, when the first annular filter screen 24 and the first drainage disk 25 are rotating, the two will contact the cleaning rod 56. At this time, the cleaning rod 56 will scrape the two, and the impurities attached to the filter surface and the drainage component can be removed in time, which further enhances the anti-blocking effect, ensures the continuous and stable progress of the filtering process, and reduces the downtime and maintenance time and cost caused by blockage;

[0041] In the second step, the two delivery pumps 32 are started by controlling the control panel 14. The two delivery pumps 32 will extract the neutralizer in the liquid storage tank 31, and then inject it into the liquid storage ring 35 through the delivery pipe 34, and then spray it out after being atomized through the atomizing net 36. Since the atomizing net 36 is also designed to be annular, the neutralizer spray sprayed out will combine with the butanedisulfonic acid waste liquid spray and condense on the inner wall of the treatment tube 11 to complete the initial mixing of the two. The atomized neutralizer and waste liquid have extremely high surface energy and activity, and the molecules between them can quickly penetrate and act on each other. The tiny size of the mist droplets and the large amount of interface area accelerate the diffusion of the substance and the rate of chemical reaction. When the two mist liquids collide and combine with each other, the neutralization reaction can be triggered almost instantly, which greatly shortens the induction period and overall time of the reaction, and significantly improves the efficiency of the entire neutralization treatment.

[0042] In the third step, the neutralizer spray will combine with the succinic acid waste liquid spray and condense on the treatment tube 11 to form water droplets. The accumulated water droplets will fall on the second drainage plate 41, and then flow to the inside of the spiral feed trough 43 through the second drainage plate 41. The mixed liquid will rotate and accelerate inside the spiral feed trough 43 and then fall into the treatment tube 11. At this time, the mixed liquid of the two will be mixed again, and then the mixed liquid will enter the inner tube 44 under the drainage action of the rotating shaft 18. At this time, the rotating shaft 18 will drive the inner tube 44 to rotate when it rotates, and when the inner tube 44 rotates, the wedge bar 49 will contact the baffle rod 19. At this time, the baffle rod 19 will be limited by the second drainage plate 41 and cannot move. The two wedge bars 49 Under the extrusion force, it will move downward. At this time, the two wedge-shaped bars 49 will drive the inner plate 46 to move downward inside the inner cylinder 44. The inner plate 46 will drive the spring 48 to be compressed. When the inner plate 46 is located below the suction port 45, the mixed liquid will flow out along the suction port 45. On the contrary, when the wedge-shaped bar 49 is not in contact with the blocking rod 19, the spring 48 will restore its deformation. At this time, the inner plate 46 rises inside the inner cylinder 44, and the space inside the inner cylinder 44 will become larger. At this time, the mixed liquid inside the treatment cylinder 11 will be sucked into the inner cylinder 44. Under repeated suction, the neutralizer and the butanedisulfonic acid waste liquid can be mixed more fully and evenly, which helps to ensure the complete conduct of the neutralization reaction and improve the treatment effect and quality.

[0043] In the fourth step, when the inner cylinder 44 rotates, the stirring blade 51 is driven to rotate. The mixed liquid in the treatment cylinder 11 is mixed by the rotation of the stirring blade 51. Compared with the existing equipment, the reaction efficiency of the neutralizer and the butanedisulfonic acid waste liquid can be greatly improved by the repeated mixing of the equipment. At this time, the pH value of the mixed liquid can be measured by the pH sensor 53, and when the discharge standard is reached, it can be discharged through the drain pipe 12;

[0044] The fifth step is to remove the bolts on the fixing ring 13, the cross frame 15 and the motor mounting frame 16 when the equipment needs to be disassembled. Then, the equipment is moved upward to leave a gap to remove the ring 23 and the second drainage plate 41. Then, the cross frame 15 and the motor mounting frame 16 together with the internal design structure can be taken out. Then, the threaded ring 21 can be rotated on the rotating shaft 18. The threaded ring 21 will drive the limit ring 22 to slide out of the notch 54 to release the limit, making the overall loading and unloading of the equipment more convenient when in use.
