Description

Technical Field

[0001] The invention relates to the field of industrial wastewater treatment equipment, in particular to an adsorption and removal device for high-valent iron ions in pentaerythritol washing water. Background Art

[0002] During the pentaerythritol production process, the washing process generates wastewater containing large amounts of high-valent iron ions. If discharged without effective treatment, these high-valent iron ions not only cause serious pollution to soil, water, and other ecological environments, disrupting the ecological balance, but may also affect the health of animals, plants, and humans through the food chain. Furthermore, if the wash water containing high-valent iron ions is directly reused or used in subsequent production, the iron 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 failure.

[0003] Currently, the main technologies used to remove high-valent iron ions from wastewater are ion exchange resin adsorption and activated carbon adsorption. While ion exchange resins have a certain ability to adsorb iron ions, they suffer from limited adsorption capacity, easy saturation, and difficulty in regeneration. Activated carbon adsorption requires frequent replacement of the adsorbent material, resulting in high operating costs. Furthermore, existing adsorption devices often lack precise regulation and effective control of the wastewater pH, which can lead to hydrolysis and precipitation of iron ions, reducing adsorption efficiency. Furthermore, most devices lack pre-filtration, which can easily clog the adsorption material with large impurities in the wastewater, affecting proper operation. Furthermore, conventional adsorption equipment often utilizes a static adsorption method, resulting in inadequate contact between the wastewater and the adsorbent material and low mass transfer efficiency, making it difficult 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 device for the removal of high-valent iron ions from pentaerythritol wash water has significant practical significance and application value.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Please see the attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides an adsorption and removal device for high-valent iron ions in pentaerythritol washing water, such as Figure 1As shown, it includes an adsorption chamber 1, which serves as the core accommodating structure of the entire device and provides a stable working space for the internal components. A chelating resin fixed adsorption bed 2 is fixedly installed on the upper side of the interior thereof. The adsorption bed 2 is filled with a chelating resin with a strong adsorption capacity for high-valent iron ions and is a key component for the preliminary adsorption of high-valent iron ions. A fluidized bed 3 is fixedly installed in the middle of the adsorption chamber 1. A groove 4 is opened in the middle of the fluidized bed 3 to provide a holding space for magnetic nano-adsorption particles 5, forming a place for secondary adsorption. A positioning seat 18 is fixedly installed in the interior of the adsorption chamber 1 near the upper position of the chelating resin fixed adsorption bed 2. The positioning seat 18 plays a role of stable support. The U-shaped liquid-passing seat 19 fixedly installed on its top is an important channel for guiding the flow of wastewater and adjusting the pH. One end of the U-shaped liquid-passing seat 19 is fixedly installed It is equipped with a liquid inlet pipe 20, which is used to introduce the wastewater that has undergone preliminary treatment into the U-shaped liquid-passing seat 19; a bending pipe 21 is movably installed at the other end, and the bending pipe 21 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 bending pipe 21, and several nozzles 35 are evenly fixedly installed at the bottom end of the arc-shaped bend pipe 34, which can spray the wastewater evenly on the surface of the chelating resin fixed adsorption bed 2. A pH regulator inlet pipe 36 is fixedly installed on the side of the top of the U-shaped liquid-passing seat 19 close to the U-shaped liquid-passing seat 19. The pH regulator can be accurately added through the inlet pipe 36 to adjust the pH value 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 on the pentaerythritol wash water entering the device and intercept large particles of impurities.

[0020] In this embodiment, a downpipe 8 is fixedly installed at the bottom end of the fluidized bed 3, and the end of the downpipe 8 extends to the inner 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 penetrate into the downpipe 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 passes through the interior of the fluidized bed 3 to provide a rotating axis for the disc magnet 7. Disc magnets 7 are fixedly installed on the outer diameters of both sides 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 and enhance the mass transfer effect.

[0022] Furthermore, a second rotating shaft 10 is movably installed at a position below the fluidized bed 3 inside the adsorption chamber 1, and a filter press plate 11 is movably installed on the lower side of the interior of the adsorption chamber 1. Cams 12 are fixedly installed on the outer diameters of both sides 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 realizing the filter pressure 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 installed with a driving wheel 14, and one end of the first rotating shaft 6 extends to the outside of the adsorption chamber 1 and is fixedly installed with a driven wheel 15. The outer diameters of the driving 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 installed on one side of the adsorption chamber 1, and the driving end of the stepper motor 17 is fixedly installed at 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, and the stepper motor 17 drives the second rotating shaft 10 to rotate. The second rotating shaft 10 drives the driving wheel 14 to rotate, and through the transmission of the transmission belt 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, and the disc magnets 7 adsorb the magnetic nano-adsorption particles 5 and drive their stirring motion. The continuously moving magnetic nano-adsorption particles 5 are used to further improve the mass transfer efficiency and enhance the adsorption effect. Then the wastewater enters the inner bottom of the adsorption chamber 1 through the seepage hole 9 and the downpipe 8, and 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 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 on one side of the U-shaped liquid-passing seat 19 near the bent pipe 21. The water wheel 22 rotates under the impact force of the wastewater flow. The middle part of the U-shaped liquid-passing seat 19 is fixedly connected to the transmission chamber 23. The middle part of the water wheel 22 extends to the interior of the transmission chamber 23 through a connecting shaft and is fixedly installed with a driving gear 24. The driving gear 24 is engaged with the inner end of a driven gear 25 movably installed on the lower side of the inner wall of the transmission chamber 23 near one end of the water wheel 22, thereby transmitting the rotational power of the water wheel 22.

[0026] Furthermore, a worm 27 is fixedly installed on the middle part of the driven gear 25 through a short shaft 26, and a transmission shaft 28 is movably installed on the inner middle part of the transmission chamber 23. A worm wheel 29 fixedly installed on the outer diameter of the middle part of the transmission shaft 28 is meshed and connected with the inner end of the worm 27 to further transmit power. A quarter-bevel gear 30 is fixedly installed on the outer diameter of both sides of the transmission shaft 28. The meshing tooth positions of the two quarter-bevel gears 30 are staggered with each other to achieve intermittent transmission. A rotating rod 31 is movably installed on the side of the U-shaped liquid-passing seat 19 away from the bending tube 21. The end of the rotating rod 31 extends to 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 is meshed and connected with the inner ends of the two quarter-bevel gears 30. The middle outer diameter of the rotating rod 31 is fixedly mounted on one end of the U-shaped connecting rod 33, and the other end of the U-shaped connecting rod 33 is fixedly mounted on the outer diameter of one side of the bending tube 21, thereby realizing the conversion of the power of the water wheel 22 into the swinging power of the bending tube 21.

[0027] Specifically, the wastewater enters the U-shaped liquid overflow seat 19 through the liquid inlet pipe 20. At this time, a pH reagent is introduced into the wastewater through the pH regulator inlet pipe 36 to accurately adjust the pH value of the wastewater to an appropriate range to prevent the hydrolysis and precipitation of iron ions from affecting the adsorption efficiency. After the wastewater flows through the U-shaped liquid overflow seat 19, it is discharged to the inside of the arc-shaped elbow 34 through the bent pipe 21 and finally ejected through the nozzle 35 and sprayed on the surface of the chelate resin fixed adsorption bed 2. The chelate resin fixed adsorption bed 2 uses the chelate resin to perform preliminary adsorption of high-valent iron ions in the wastewater. During this period, the flow of wastewater will drive the water wheel 22 to rotate, and the water wheel 22 drives the driving gear 24 to rotate through the connecting shaft. The rotating driving gear 24 and the driven gear The wheel 25 meshes and drives the worm 27 to rotate. The worm 27 meshes and drives 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 with each other, when the transmission shaft 28 rotates, the two quarter-bevel gears 30 will intermittently mesh and drive with the transmission bevel gear 32, thereby driving the rotating rod 31 to swing back and forth. The rotating rod 31 drives the bending pipe 21, the arc-shaped bending pipe 34 and the nozzle 35 to swing back and forth through the U-shaped connecting rod 33, spraying the wastewater evenly on the surface of the chelating resin fixed adsorption bed 2, so that the wastewater is in full contact with the chelating resin fixed adsorption bed 2, thereby greatly improving the adsorption efficiency.

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

[0029] Working principle: First, start the delivery pump 39. The delivery pump 39 serves as a power source to pump the pentaerythritol washing water into the wastewater outlet pipe 41 through the wastewater inlet pipe 40. The wastewater will enter the filter chamber 37. The filter cartridge 38 plays an interception role and performs preliminary filtration on the wastewater to remove large particles of impurities therein to prevent impurities from affecting subsequent adsorption treatment. Subsequently, the wastewater enters the U-shaped liquid seat 19 through the liquid inlet pipe 20. At this time, a pH reagent is introduced into the wastewater through the pH regulator inlet pipe 36 to accurately adjust the pH value of the wastewater to an appropriate range to prevent the hydrolysis and precipitation of iron ions from affecting the adsorption efficiency. After the wastewater flows through the U-shaped liquid seat 19, it is discharged to the arc elbow 3 through the bent pipe 21. 4, and finally sprayed out through the nozzle 35, sprayed on the surface of the chelate resin fixed adsorption bed 2, the chelate resin fixed adsorption bed 2 uses the chelate resin to perform preliminary adsorption on the high-valent iron ions in the wastewater, during which the flow of wastewater drives the water wheel 22 to rotate, and the water wheel 22 drives the driving gear 24 to rotate through the connecting shaft, and the rotating driving gear 24 is meshed with the driven gear 25 to drive the worm 27 to rotate, and the worm 27 is meshed with the worm wheel 29 to drive 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 are meshed with each other. The wheel 30 is intermittently meshed with the transmission bevel gear 32 for transmission, thereby driving the rotating rod 31 to swing back and forth. The rotating rod 31 drives the bending pipe 21, the arc-shaped bending pipe 34 and the nozzle 35 to swing back and forth through the U-shaped connecting rod 33, and the wastewater is evenly sprayed on the surface of the chelate resin fixed adsorption bed 2, so that the wastewater is fully in contact with the chelate resin fixed adsorption bed 2, which greatly improves the adsorption efficiency. Subsequently, the wastewater will flow into the groove 4 of the fluidized bed 3, and the magnetic nano-adsorption particles 5 will play a role in secondary adsorption of the high-valent iron ions remaining in the wastewater. At the same time, the stepping motor 17 is started, and the stepping motor 17 drives the second rotating shaft 10 to rotate, and the second rotating shaft 10 drives the driving wheel 14 to rotate, and the wastewater is evenly sprayed on the surface of the chelate resin fixed adsorption bed 2. The transmission of 16 drives the driven wheel 15 and the first rotating shaft 6 to rotate, and the first rotating shaft 6 drives the disc magnets 7 on both sides to rotate. The disc magnets 7 adsorb the magnetic nano-adsorption particles 5 and drive their stirring motion. The continuously moving magnetic nano-adsorption particles 5 are used to further improve the mass transfer efficiency and the adsorption effect. Then the wastewater enters the inner bottom of the adsorption chamber 1 through the seepage hole 9 and the downpipe 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 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.
