Description

Technical Field

[0001] This invention relates to the field of industrial wastewater treatment equipment, specifically to an adsorption and removal device based on pentaerythritol washing water containing high-valence iron ions. Background Technology

[0002] During the production of pentaerythritol, the washing process generates wastewater containing large amounts of ferric ions. If this ferric ion is discharged directly without effective treatment, it will not only cause serious pollution to soil and water bodies, disrupting the ecological balance, but may also affect the health of animals, plants, and humans through the food chain. Furthermore, if the wastewater containing ferric ions is directly reused or used in subsequent production, the ferric ions will participate in chemical reactions, leading to a decline in product quality, affecting the purity and performance of pentaerythritol, and increasing production costs and the risk of product defects.

[0003] Currently, the adsorption and removal of high-valent iron ions from wastewater mainly employs technologies such as ion exchange resin adsorption and activated carbon adsorption. While ion exchange resins have a certain adsorption capacity for iron ions, they suffer from limited adsorption capacity, easy saturation, and difficulty in regeneration. Activated carbon adsorption requires frequent replacement of the adsorption material, resulting in high operating costs. Furthermore, existing adsorption devices often lack precise adjustment and effective control of the wastewater's pH value, leading to the easy hydrolysis and precipitation of iron ions, reducing adsorption efficiency. Moreover, most lack pre-filtration structures, allowing large particulate impurities in the wastewater to clog the adsorption material and affect the normal operation of the device. Simultaneously, traditional adsorption equipment often employs static adsorption, resulting in insufficient contact between the wastewater and the adsorption material, leading to low mass transfer efficiency and failing to meet the requirements for efficient removal of high-valent iron ions from pentaerythritol wash water. Therefore, developing an efficient, stable, and low-cost adsorption and removal device for high-valent iron ions in pentaerythritol wash water has significant practical significance and application value. Summary of the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Please see the appendix Figure 1 - Appendix Figure 8 This invention provides an adsorption and removal device for high-valent iron ions in pentaerythritol wash water, such as... Figure 1As shown, the device includes an adsorption chamber 1, which serves as the core structure of the entire apparatus, providing a stable working space for all internal components. A chelating resin fixed adsorption bed 2 is fixedly installed on its upper side. This adsorption bed 2 is filled with chelating resin that has a strong adsorption capacity for high-valence iron ions and is a key component for the initial adsorption of high-valence iron ions. A fluidized bed 3 is fixedly installed in the middle of the adsorption chamber 1. A groove 4 in the middle of the fluidized bed 3 provides a space for magnetic nanoparticles 5, forming a site for secondary adsorption. A positioning seat 18 is fixedly installed inside the adsorption chamber 1 near the top of the chelating resin fixed adsorption bed 2. The positioning seat 18 provides stable support, and a U-shaped liquid-passing seat 19 is fixedly installed at its top, serving as an important channel for guiding wastewater flow and adjusting pH. One end of the U-shaped liquid-passing seat 19 is fixedly installed... The device is equipped with an inlet pipe 20 for introducing pre-treated wastewater into a U-shaped liquid-passing seat 19; a bent pipe 21 is movably installed at the other end, which can swing under the drive of the transmission structure to change the flow direction of the wastewater. An arc-shaped bend pipe 34 is fixedly installed at the end of the bend pipe 21, and several nozzles 35 are evenly fixedly installed at the bottom of the arc-shaped bend pipe 34, which can evenly spray the wastewater onto the surface of the chelating resin fixed adsorption bed 2. A pH adjustment agent inlet pipe 36 is fixedly installed on the top of the U-shaped liquid-passing seat 19 near the side of the U-shaped liquid-passing seat 19, through which a pH adjustment agent can be precisely added to adjust the acidity and alkalinity of the wastewater. A filter chamber 37 is fixedly installed on one side of the middle of the adsorption chamber 1, and a filter cartridge 38 is fixedly installed inside the filter chamber 37, which can perform preliminary filtration of the pentaerythritol wash water entering the device and intercept large particulate impurities.

[0020] In this embodiment, a liquid drain pipe 8 is fixedly installed at the bottom of the fluidized bed 3. The end of the liquid drain pipe 8 extends to the bottom of the adsorption chamber 1. Its function is to guide the wastewater after secondary adsorption by the fluidized bed 3 to flow downward. Several seepage holes 9 are opened on the bottom wall of the groove 4 so that the wastewater can smoothly permeate into the liquid drain pipe 8 and enter the bottom of the adsorption chamber 1.

[0021] Furthermore, a first rotating shaft 6 is movably installed in the middle of the adsorption chamber 1. The middle of the first rotating shaft 6 penetrates the interior of the fluidized bed 3, providing a rotating shaft for the disc magnet 7. Disc magnets 7 are fixedly installed on both outer diameters of the first rotating shaft 6. When the disc magnet 7 rotates, it can adsorb and drive the magnetic nano-adsorption particles 5 to stir, thereby enhancing the mass transfer effect.

[0022] Furthermore, a second rotating shaft 10 is movably installed inside the adsorption chamber 1 near the lower part of the fluidized bed 3, and a filter press plate 11 is movably installed on the lower side of the adsorption chamber 1. Cams 12 are fixedly installed on both outer diameters of the second rotating shaft 10. The cams 12 are connected to the filter press plate 11 through a connecting rod 13. When the second rotating shaft 10 rotates, the cams 12 drive the filter press plate 11 to move up and down through the connecting rod 13, thereby achieving filter pressing treatment of the wastewater at the bottom of the adsorption chamber 1.

[0023] Furthermore, one end of the second rotating shaft 10 extends to the outside of the adsorption chamber 1 and is fixedly mounted with a drive wheel 14, and one end of the first rotating shaft 6 extends to the outside of the adsorption chamber 1 and is fixedly mounted with a driven wheel 15. The outer diameters of the drive wheel 14 and the driven wheel 15 are connected by a transmission belt 16 to form a transmission structure. A stepper motor 17 is fixedly mounted on one side of the adsorption chamber 1, and the drive end of the stepper motor 17 is fixedly mounted on one end of the second rotating shaft 10 to provide a power source for the entire transmission system.

[0024] Specifically, the stepper motor 17 is started, which drives the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the drive wheel 14 to rotate, which in turn drives the driven wheel 15 and the first rotating shaft 6 to rotate via the transmission belt 16. The first rotating shaft 6 drives the disc magnets 7 on both sides to rotate. The disc magnets 7 adsorb magnetic nanoparticles 5 and drive them to stir. The continuously moving magnetic nanoparticles 5 further improve the mass transfer efficiency and enhance the adsorption effect. Subsequently, the wastewater enters the bottom of the adsorption chamber 1 through the seepage hole 9 and the drain pipe 8. When the second rotating shaft 10 rotates, it also drives the cams 12 on both sides to rotate. The rotating cams 12 drive the filter plate 11 to move up and down through the connecting rod 13, thereby continuously pressing and filtering the wastewater at the bottom of the adsorption chamber 1 to further purify the water quality. Finally, the treated wastewater is discharged through the drain pipe 42.

[0025] Furthermore, a water wheel 22 is movably installed inside the U-shaped liquid-passing seat 19 near the side of the bent pipe 21. The water wheel 22 rotates under the impact force of the wastewater flow. A transmission chamber 23 is fixedly connected to the middle of the U-shaped liquid-passing seat 19. The middle of the water wheel 22 extends into the interior of the transmission chamber 23 through a connecting shaft and a drive gear 24 is fixedly installed thereon. The drive gear 24 meshes with the inner end of the driven gear 25 movably installed on the lower side of the inner wall of the transmission chamber 23 near the end of the water wheel 22, thereby transmitting the rotational power of the water wheel 22.

[0026] Furthermore, a worm gear 27 is fixedly installed in the middle of the driven gear 25 via a short shaft 26. A transmission shaft 28 is movably installed in the middle of the transmission chamber 23. A worm wheel 29 fixedly installed on the outer diameter of the middle of the transmission shaft 28 meshes with the inner end of the worm gear 27 to further transmit power. Quarter bevel gears 30 are fixedly installed on both outer diameters of the transmission shaft 28. The meshing teeth of the two quarter bevel gears 30 are staggered to achieve intermittent transmission. A rotating rod 31 is movably installed on the side of the U-shaped liquid seat 19 away from the bent pipe 21. The end of the rotating rod 31 extends into the interior of the transmission chamber 23 and is fixedly installed with a transmission bevel gear 32. The outer end of the transmission bevel gear 32 meshes with the inner ends of the two quarter bevel gears 30. The middle outer diameter of the rotating rod 31 is fixedly installed on one end of the U-shaped connecting rod 33. The other end of the U-shaped connecting rod 33 is fixedly installed on one outer diameter of the bent pipe 21, thereby converting the power of the water turbine 22 into the oscillating power of the bent pipe 21.

[0027] Specifically, wastewater enters the U-shaped liquid-passing seat 19 through the inlet pipe 20. At this time, pH reagent is introduced into the wastewater through the pH adjustment agent introduction pipe 36 to precisely adjust the pH value of the wastewater to a suitable range, preventing the hydrolysis and precipitation of iron ions from affecting the adsorption efficiency. After flowing through the U-shaped liquid-passing seat 19, the wastewater is discharged into the arc-shaped bend pipe 34 through the bend pipe 21, and finally sprayed out through the nozzle 35 onto the surface of the chelating resin fixed adsorption bed 2. The chelating resin fixed adsorption bed 2 uses chelating resin to initially adsorb high-valence iron ions in the wastewater. During this process, the flow of wastewater will drive the water wheel 22 to rotate. The water wheel 22 drives the drive gear 24 to rotate through the connecting shaft. The rotating drive gear 24 and driven gear The gear 25 engages in a meshing transmission, driving the worm 27 to rotate. The worm 27 meshes with the worm wheel 29, thereby driving the transmission shaft 28 and the quarter-bevel gears 30 on both sides of the transmission shaft 28 to rotate. Since the meshing teeth of the two quarter-bevel gears 30 are staggered, when the transmission shaft 28 rotates, the two quarter-bevel gears 30 will intermittently mesh with the transmission bevel gear 32, thereby driving the rotating rod 31 to swing back and forth. The rotating rod 31 drives the bent tube 21, the arc-shaped bent tube 34 and the nozzle 35 to swing back and forth through the U-shaped connecting rod 33, so that the wastewater is evenly sprayed on the surface of the chelating resin fixed adsorption bed 2, so that the wastewater and the chelating resin fixed adsorption bed 2 are in full contact, greatly improving the adsorption efficiency.

[0028] Furthermore, the end of the inlet pipe 20 extends to the top of the filter chamber 37 to receive the filtered wastewater. A transfer pump 39 is fixedly installed on one side of the adsorption chamber 1 near the lower part of the filter chamber 37. A wastewater inlet pipe 40 is fixedly installed at the input end of the transfer pump 39, and a wastewater outlet pipe 41 is fixedly installed at the output end. The end of the wastewater outlet pipe 41 penetrates the bottom wall of the filter chamber 37 and extends into the interior of the filter cartridge 38 to form a wastewater transport channel. A drain pipe 42 is fixedly installed on the lower front side of the adsorption chamber 1 to discharge the treated wastewater that meets the standards.

[0029] Working principle: First, the transfer pump 39 is started. Using the transfer pump 39 as a power source, the pentaerythritol wash water is pumped through the wastewater inlet pipe 40 into the wastewater outlet pipe 41. The wastewater then enters the filter chamber 37, where the filter cartridge 38 acts as an interceptor, performing preliminary filtration to remove large particles and prevent them from affecting subsequent adsorption treatment. The wastewater then enters the U-shaped liquid-passing seat 19 through the liquid inlet pipe 20. At this point, a pH reagent is introduced into the wastewater through the pH adjustment agent inlet pipe 36 to precisely adjust the pH value to a suitable range, preventing iron ion hydrolysis and precipitation from affecting adsorption efficiency. After flowing through the U-shaped liquid-passing seat 19, the wastewater is discharged through the bent pipe 21 into the arc-shaped bend pipe 3. 4. The solution is sprayed from inside the chelating resin fixed adsorption bed 2 through nozzle 35. The chelating resin fixed adsorption bed 2 uses chelating resin to initially adsorb high-valence iron ions in the wastewater. During this process, the flow of wastewater will drive the water wheel 22 to rotate. The water wheel 22 drives the drive gear 24 to rotate through the connecting shaft. The rotating drive gear 24 meshes with the driven gear 25, driving the worm 27 to rotate. The worm 27 meshes with the worm wheel 29, thereby driving the drive shaft 28 and the quarter-bevel gears 30 on both sides of the drive shaft 28 to rotate. Since the meshing teeth of the two quarter-bevel gears 30 are misaligned, when the drive shaft 28 rotates, the two quarter-bevel gears will... The wheel 30 intermittently meshes with the transmission bevel gear 32, thereby driving the rotating rod 31 to swing back and forth. The rotating rod 31 drives the bent tube 21, the arc-shaped bent tube 34, and the nozzle 35 to swing back and forth through the U-shaped connecting rod 33, uniformly spraying the wastewater onto the surface of the chelating resin fixed adsorption bed 2, so that the wastewater and the chelating resin fixed adsorption bed 2 are in full contact, greatly improving the adsorption efficiency. Subsequently, the wastewater flows into the groove 4 of the fluidized bed 3, where the magnetic nano-adsorption particles 5 play a role in the secondary adsorption of residual high-valence iron ions in the wastewater. At the same time, the stepper motor 17 is started, which drives the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the drive wheel 14 to rotate, which is transmitted through the transmission belt. The transmission of shaft 16 drives the driven wheel 15 and the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the disc magnets 7 on both sides to rotate. The disc magnets 7 adsorb magnetic nano-adsorption particles 5 and drive them to stir. The continuously moving magnetic nano-adsorption particles 5 further improve the mass transfer efficiency and enhance the adsorption effect. Subsequently, the wastewater enters the bottom of the adsorption chamber 1 through the seepage hole 9 and the liquid outlet pipe 8. When the second rotating shaft 10 rotates, it also drives the cams 12 on both sides to rotate. The rotating cams 12 drive the filter press plate 11 to move up and down through the connecting rod 13, thereby continuously pressing and filtering the wastewater at the bottom of the adsorption chamber 1 to further purify the water quality. Finally, the treated wastewater is discharged through the drain pipe 42.
