Description

Technical Field

[0001] This invention relates to the technical field of advanced oxidation devices for fabric printing and dyeing processes, and more specifically, to an advanced oxidation device for deep treatment of wastewater from fabric printing and dyeing processes. Background Technology

[0002] As is well known, the dyeing and printing process of fabrics generates a large amount of wastewater due to its working sequence, and this wastewater usually contains a variety of chemical components and pollutants.

[0003] Specifically, the wastewater generated from fabric dyeing and printing is composed of a mixture of dyes and pigments, auxiliaries, surfactants, heavy metal ions, acidic and alkaline substances, organic matter, suspended solids, and biodegradable substances, which ultimately constitute the wastewater discharged from the factory.

[0004] Although wastewater treatment in fabric dyeing and printing is quite difficult, we now have relatively mature treatment equipment for this purpose. However, after a long period of observation, we have found some areas for improvement in the advanced oxidation equipment used in the wastewater treatment process.

[0005] For example, existing advanced oxidation devices, especially photocatalytic oxidation devices, are often used as stand-alone units, making it impossible to measure the amount of wastewater produced at the work site and difficult to use in combination. This can easily lead to a waste of capacity in areas with low wastewater production, while in areas with high wastewater production, it is difficult to fully utilize its own capacity. This can easily result in a single device being used for multiple treatments, which greatly reduces the oxidation efficiency of the device.

[0006] Therefore, we have designed an advanced oxidation device for the deep treatment of wastewater from fabric dyeing and printing processes, which can be processed in blocks and layers. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An advanced oxidation device for deep treatment of wastewater from fabric dyeing and printing processes includes a modular advanced oxidation device body. The top of the modular advanced oxidation device body is equipped with an advanced oxidation device top cover. An inlet is located on the upper side of the modular advanced oxidation device body, and an outlet is located on the lower side of the modular advanced oxidation device body. Modular advanced oxidation device side plates are arranged inside the modular advanced oxidation device body. Specifically, the modular advanced oxidation device body is composed of multiple modular advanced oxidation device side plates assembled together. The inlet and outlet are formed by disassembling the modular advanced oxidation device side plates. A modular bottom plate is arranged inside each modular advanced oxidation device side plate, forming the bottom and top of the modular advanced oxidation device side plate during assembly. The catalyst sheet... The surface of the soft plate is equipped with an ultraviolet lamp tube. The upper surface of the spliced ​​base plate is provided with a catalyst plate. The interior of the spliced ​​side plate of the advanced oxidation device is provided with a rotating stirring shaft. The surface of the rotating stirring shaft is inserted with rotating stirring blades. The surface of the rotating stirring shaft has multiple notches for inserting the rotating stirring blades. The surface of the rotating stirring shaft is spirally surrounded by a stirring guide ring. The interior of the spliced ​​advanced oxidation device body is provided with a water inlet. The water inlet is specifically formed by splicing the spliced ​​side plates of the advanced oxidation device. The side of the spliced ​​base plate near the water inlet is movably connected to a fitting positioning guide shaft. The surface of the fitting positioning guide shaft is fixedly connected to the catalyst plate. The fitting positioning guide shaft is used to roll up the catalyst plate covering the top of the spliced ​​base plate.

[0009] The ultraviolet lamps are arranged diagonally and installed on the surface of the catalyst plate placement plate. The catalyst plate placement plate is detachable and assembleable, mounted on top of a modular base plate. The catalyst plate placement plate has a connecting groove inside, and a connecting positioning band is provided inside the connecting groove for assembling and connecting the catalyst plate placement plate. A positioning pull rod is connected through the inside of the catalyst plate placement plate, and the positioning pull rod is also connected through the inside of a fitting positioning guide shaft. A positioning and tightening bottom ring is provided at the end of the positioning pull rod near the fitting positioning guide shaft for tightening and fixing the positioning pull rod. The modular base plate is stepped, and a friction positioning plate is provided on the surface of the modular base plate. A fitting locking rod is provided on the side of the modular base plate near the fitting positioning guide shaft, and a placement guide rod is sleeved on the surface of the fitting locking rod.

[0010] Furthermore, one end of the guide rod abuts against the inner wall of the advanced oxidation device's modular side plate. The inner wall of the modular side plate is provided with a load-bearing groove for supporting the guide rod. Both sides of the modular base plate near the modular side plate are provided with a soft material for sealing the modular base plate. This soft material is removable. All four walls of the modular side plate are semi-hollow. The inner wall of the modular side plate is provided with a snap-fit ​​interface for mounting the rotating stirring shaft. The inner wall of the modular side plate is also provided with a plug-in groove for mounting the snap-fit ​​rod.

[0011] Furthermore, the ultraviolet lamp tube has a lamp strip fitting rod inside, and an ultraviolet lamp strip is inserted through the lamp strip fitting rod. The lamp strip fitting rod is made of light-transmitting material. The ultraviolet lamp tube has six sides. Side diffuser lenses are provided on the sides of the ultraviolet lamp tube. The side diffuser lenses are provided on the four sides of the ultraviolet lamp tube and are installed symmetrically. Positive refraction lenses are provided at the top and bottom of the ultraviolet lamp tube. The bottom angle of the positive refraction lenses does not exceed °.

[0012] Furthermore, a trapezoidal through groove is provided inside the rotating stirring shaft blade. The trapezoidal through groove is wider at the front and narrower at the back. Refraction and breaking frames are provided on both sides of the rotating stirring shaft blade. The bottom of the refraction and breaking frames is rounded, and the top of the refraction and breaking frames is right-angled. The opening direction of the refraction and breaking frames and the trapezoidal through groove matches the rotation direction of the rotating stirring shaft blade.

[0013] Furthermore, the ultraviolet lamp tube is also installed at the bottom of the spliced ​​base plate, and a light-transmitting mirror is installed at the bottom of the spliced ​​base plate. The light-transmitting mirror fits the surface of the spliced ​​base plate, and the bottom surface of the spliced ​​base plate is coated with a reflective coating. The bottom of the spliced ​​base plate also has a stepped groove. The reflective coating is sealed between the spliced ​​base plate and the light-transmitting mirror. The bottom of the spliced ​​base plate is used to assist in refracting the light emitted by the ultraviolet lamp tube. The stepped corners at the bottom and top of the spliced ​​base plate are arranged symmetrically in opposite directions.

[0014] In summary, the present invention has the following beneficial effects:

[0015] By setting up a modular base plate and other related mechanisms, the modular design of the device can be completed, which can effectively match the wastewater output of the area of ​​use and then be used in a coordinated manner. This ensures that the device's production capacity will not be wasted due to a small amount of wastewater. At the same time, the stacking design can minimize the footprint of the device during use, and it can also control costs for manufacturers with insufficient area.

[0016] By placing catalyst sheets on flexible plates and other related structures, ultraviolet lamps can be used in conjunction with them, which increases the photo-reaction efficiency of the device in terms of structure. It can complete the functions of folding the light-illuminated area, light refraction, and light diffusion in a limited space, which greatly increases the photo-oxidation efficiency of the modular advanced oxidation device.

[0027] The technical solutions of 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.

[0028] Example 1:

[0029] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0030] Please see Figure 1-7 This invention provides a technical solution: an advanced oxidation device for deep treatment of wastewater from fabric dyeing and printing processes, such as... Figure 1-7As shown, the device includes a modular advanced oxidation unit body 1, with an advanced oxidation unit top cover 2 on the top, a device inlet 4 on the upper side, and a device outlet 5 on the lower side. Modular advanced oxidation unit side plates 3 are installed inside the modular advanced oxidation unit body 1. Specifically, the modular advanced oxidation unit body 1 is composed of multiple modular advanced oxidation unit side plates 3 assembled together. Both the device inlet 4 and the device outlet 5 are advanced oxidation unit components. The advanced oxidation unit's spliced ​​side plate 3 is constructed by disassembling the original side plate 3. Inside the spliced ​​side plate 3, a spliced ​​bottom plate 6 is installed. The spliced ​​bottom plate 6 forms the bottom and top of the advanced oxidation unit's spliced ​​side plate 3 during assembly. A catalyst plate placement flexible plate 7 is provided on the upper surface of the spliced ​​bottom plate 6. Inside the advanced oxidation unit's spliced ​​side plate 3, a rotating stirring shaft 8 is installed. Rotating stirring blades 9 are inserted into the surface of the rotating stirring shaft 8. Multiple notches are provided on the surface of the rotating stirring shaft 8 for inserting the rotating stirring blades 9. A stirring guide is spirally arranged around the surface of the rotating stirring shaft 8. Ring 10, the interior of the modular advanced oxidation unit body 1 has a water inlet 11. The water inlet 11 is specifically formed by splicing the modular side plates 3 of the advanced oxidation unit. A fitting positioning guide shaft 12 is movably connected to the side of the modular base plate 6 near the water inlet 11. The surface of the fitting positioning guide shaft 12 is fixedly connected to the catalyst sheet placement flexible plate 7. The fitting positioning guide shaft 12 is used to roll up the catalyst sheet placement flexible plate 7 covering the top of the modular base plate 6. Now we will briefly expand on the parts described above. First, it should be noted that the splicing... The main body 1 of the advanced oxidation device is constructed by splicing several advanced oxidation device side plates 3. During the splicing process of the advanced oxidation device side plates 3, they can be cumulatively stacked according to the working environment. The usage background is explained in detail here: this device is a link in the entire deep wastewater treatment process, a pre-treatment device for the advanced oxidation equipment, requiring pre-treatment of wastewater. This device is located in the tertiary treatment stage of the entire wastewater treatment process, with the primary treatment stage being the initial treatment; its purpose is to remove large particulate suspended solids and other solid matter from the wastewater.The secondary treatment stage aims to remove soluble organic matter and some suspended solids from wastewater, degrading organic pollutants through biochemical processes. The tertiary treatment stage is advanced treatment, aiming to further remove remaining pollutants to achieve higher water quality standards, particularly for nutrients such as nitrogen and phosphorus. Based on this, wastewater from the pretreatment stage can be introduced into this device, entering the interior of the modular advanced oxidation unit 1 through the inlet 4. The wastewater undergoes oxidation treatment through the modular side plates 3 of the advanced oxidation unit. During this process, the wastewater is preferentially retained inside the modular side plates 3. At this point, the operator can start the rotating agitator shaft 8, causing it to rotate. During this rotation, the rotating agitator blades 9 also rotate. It should be noted that during the rotation of the rotating agitator shaft 8, the agitator guide ring 10 on its surface rotates simultaneously with the shaft. Because the agitator guide ring 10 is... The spiral shape is formed on the surface of the rotating stirring shaft 8. As the rotating stirring shaft 8 rotates, due to the centrifugal force of high-speed rotation, a layer of air-bursting film will be formed on the surface of the rotating stirring shaft 8. Thus, the opening of the stirring guide ring 10 can increase the stirring effect of the rotating stirring shaft 8 itself, so that the internal sewage of the modular advanced oxidation device 1 can better contact the catalyst on the surface of the catalyst plate placement soft plate 7 during the stirring process. In addition, different flow areas can be changed during the contact process, so that the flow areas can be better exposed to light source irradiation, thereby improving the oxidation reaction efficiency of the sewage. Moreover, the setting of the catalyst plate placement soft plate 7 and the embedded positioning guide shaft 12 ensures that the catalyst plate placement soft plate 7 can be rolled up and replaced more effectively during the use of the device. This ensures that the cleaning process of the device is not as cumbersome as that of previous devices. The user only needs to use the embedded positioning guide shaft 12 to directly roll up the catalyst plate placement soft plate 7 for replacement, thereby ensuring the efficiency of the device's use and replacement.

[0031] Ultraviolet lamps 17 are installed on the surface of the catalyst plate placement flexible plate 7. The ultraviolet lamps 17 are arranged diagonally on the surface of the catalyst plate placement flexible plate 7. Specifically, the catalyst plate placement flexible plate 7 is detachable and assembled on the top of the spliced ​​base plate 6. The catalyst plate placement flexible plate 7 has a connecting slot 15 inside, and a connecting positioning band 16 is set inside the connecting slot 15. The connecting positioning band 16 is used to assemble and connect the catalyst plate placement flexible plate 7. A positioning pull rod 13 is connected through the inside of the catalyst plate placement flexible plate 7. The positioning pull rod 13 is also connected through the inside of the fitting positioning guide shaft 12. A positioning and gathering bottom ring 14 is set at the end of the positioning pull rod 13 near the fitting positioning guide shaft 12. The bottom ring 14 is used to secure and fix the pull rod 13. The spliced ​​base plate 6 is stepped, and a friction positioning plate 18 is provided on the surface of the spliced ​​base plate 6. A fitting rod 19 is provided on the side of the spliced ​​base plate 6 near the fitting positioning guide shaft 12. A placement guide rod 20 is sleeved on the surface of the fitting rod 19. It should be emphasized that the placement guide rod 20 is extremely thin near the front end ring, and is only used to connect the front end of the placement guide rod 20. At the same time, the highest angle of the placement guide rod 20 cannot be higher than the installation position of the rotating stirring shaft 8, so as to avoid the normal setting and use of the rotating stirring shaft 8. It should also be emphasized that although the spliced ​​base plate 6 itself is stepped, in order to avoid sewage residue, Furthermore, to ensure easy cleaning for users, all stepped joints of the modular base plate 6 are rounded, allowing for proper drainage and preventing water accumulation. Similarly, based on its length axis, the modular base plate 6 is designed with a higher center and lower sides during manufacturing, ensuring rapid drainage from the sides without affecting its operation. Now, we need to further address the placement of the catalyst plate placement soft plate 7. Since the device itself is modular, ease of use is prioritized. This is achieved through the positioning pull rod 13 and the interlocking positioning guide... The shaft 12 is bound together, and the positioning pull rod 13 can directly penetrate the catalyst plate placement soft plate 7 during the binding process of the top cover 2 of the advanced oxidation device. Therefore, when the device is being retracted, we only need to pull upwards to lift the entire catalyst plate placement soft plate 7, and then pull it backwards to directly retract the fitting positioning guide shaft 12 along with the catalyst plate placement soft plate 7, thereby effectively ensuring the disassembly and cleaning effect of the device. During the placement process, we only need to roll up the cleaned catalyst plate placement soft plate 7 first, and then, guided by the placement guide rod 20, the fitting positioning guide shaft 12 can be reset, so that the device can continue to be used.

[0032] In this embodiment, it is important to note that the modular base plate 6 can also be used as an independent device. We can see that the rotating stirring shaft 8 was conceived from the outset as a modular device, meaning multiple rotating stirring shafts 8 are mounted coaxially. As shown in the illustration, the modular advanced oxidation device body 1 is an independent device with a folded height and device outlet 5 and device inlet 4. However, if the company has already constructed a large-scale open-air tanning tank, then only the modular base plate 6 needs to be disassembled. Lay it at the bottom of the pool, and by passing the rotating stirring shaft 8 through it coaxially, a support frame for supporting the rotating stirring shaft 8 is set between the two spliced ​​base plates 6. Then the rotating stirring shaft 8 can still be driven by the drive source, and the rotation principle of the rotating stirring shaft 8 is the same as that of an ordinary rotating shaft. In order to facilitate the replacement of reagents by the user, we can also connect the fitting positioning guide shaft 12 as a coaxial series, so as to converge them together, thereby ensuring the working efficiency of the spliced ​​base plate 6. Therefore, as one way of using this device, we propose it here.

[0033] like Figure 1-7 As shown, one end of the guide rod 20 abuts against the inner wall of the advanced oxidation device spliced ​​side plate 3. The inner wall of the advanced oxidation device spliced ​​side plate 3 is provided with a load-bearing groove for supporting the guide rod 20. The spliced ​​base plate 6 is provided with soft material for sealing the spliced ​​base plate 6 on both sides near the advanced oxidation device spliced ​​side plate 3. The soft material is removable. The four walls of the advanced oxidation device spliced ​​side plate 3 are semi-hollow. The inner wall of the advanced oxidation device spliced ​​side plate 3 is provided with a snap-fit ​​interface for mounting the rotating stirring shaft 8. The inner wall of the advanced oxidation device spliced ​​side plate 3 is also provided with a plug-in groove for mounting the snap-fit ​​rod 19.

[0034] In this embodiment, it is worth noting that during use, the main stress point of the placement guide rod 20 is supported by the advanced oxidation device spliced ​​side plate 3. Simultaneously, the load-bearing groove supporting the placement guide rod 20 is filled with a sealant to seal the connection between the advanced oxidation device spliced ​​side plate 3 and the placement guide rod 20, preventing wastewater from entering and causing corrosion. Furthermore, the thinner portion at the connection between the placement guide rod 20 and the interlocking clamp rod 19 allows for effective disassembly of the placement guide rod 20 when used with the advanced oxidation device spliced ​​side plate 3, facilitating its removal from the interior of the advanced oxidation device spliced ​​side plate 3. Also, referring to the above embodiment, when the spliced ​​base plate 6 is used as an independent device in the basting tank, the placement guide rod 20 can be disassembled. During disassembly, the interlocking clamp rod 19 can penetrate left and right to complete the splicing. The partial fixing effect of the horizontal splicing of the base plate 6 is evident. Furthermore, it can be seen that the catalyst plate placement soft plate 7 is placed on the surface of the spliced ​​base plate 6 during use, with the spliced ​​base plate 6 serving as the overall support. The spliced ​​base plate 6 is divided into two parts for use. When installed inside the advanced oxidation unit's spliced ​​side plate 3 as a single component, it receives lateral force support by not directly overlapping one side of the inner wall of the advanced oxidation unit's spliced ​​side plate 3. During this process, the bottom of the spliced ​​base plate 6 on the side of the water inlet 11 should be equipped with a bracket for abutment or support to assist in the installation of the spliced ​​base plate 6. This ensures that the spliced ​​base plate 6 is not only clamped and fixed on three sides by the advanced oxidation unit's spliced ​​side plate 3. Therefore, this design ensures that the spliced ​​base plate 6 can be disassembled as an independent device without affecting its stability inside the advanced oxidation unit's spliced ​​side plate 3.

[0035] like Figure 1-7 As shown, the ultraviolet lamp tube 17 has a lamp strip fitting rod 21 inside, and an ultraviolet lamp strip is inserted through the lamp strip fitting rod 21. The lamp strip fitting rod 21 is made of light-transmitting material. The ultraviolet lamp tube 17 has six sides. The sides of the ultraviolet lamp tube 17 are provided with side diffuser lenses 22. The side diffuser lenses 22 are provided on the four sides of the ultraviolet lamp tube 17 and are installed symmetrically. The top and bottom of the ultraviolet lamp tube 17 are provided with positive refraction lenses 23. The bottom angle of the positive refraction lens 23 does not exceed 90°.

[0036] In this embodiment, the ultraviolet lamp 17 is also installed in a right-angle progressive manner on the surface of the catalyst sheet placement plate 7, referring to... Figure 4From the detailed introduction, we can see that this installation method, while ensuring the irradiation coverage radius of the ultraviolet lamp tube 17, allows the two ultraviolet lamp tubes 17 to combine and irradiate together, forming a common irradiation area. This significantly increases the irradiation range for the same irradiation length. Furthermore, constructing the ultraviolet lamp tube 17 with a hexagonal irradiation angle further expands its irradiation angle range. As we can see, by setting the side diffuser lens 22 as a convex lens with a curvature according to the above formula, it should divide the light inside the ultraviolet lamp tube 17, thus scattering the light source. Therefore, the light inside the ultraviolet lamp tube 17... The light source has three irradiation directions: upward irradiation, in which the light is diffused while being refracted by the positive refraction lens 23, and reflected by the other devices to achieve the highest irradiation efficiency with the lowest irradiation intensity; or oblique upward irradiation, in which the side diffuser lens 22 assists the positive refraction lens 23 in irradiation, and can also irradiate downward, forming an overlapping irradiation area. Furthermore, the side diffuser lens 22, which is obliquely below the ultraviolet lamp tube 17, photocatalyzes the catalyst covering the surface of the catalyst plate 7, thereby greatly improving the efficiency of the combined oxidation reaction of the device.

[0037] like Figure 1-7 As shown, a trapezoidal through groove 25 is provided inside the rotating stirring blade 9. The trapezoidal through groove 25 is wider at the front and narrower at the back. Refraction and crushing frames 24 are provided on both sides of the rotating stirring blade 9. The bottom of the refraction and crushing frame 24 is rounded and the top of the refraction and crushing frame 24 is right-angled. The opening direction of the refraction and crushing frame 24 and the trapezoidal through groove 25 matches the rotation direction of the rotating stirring blade 9.

[0038] In this embodiment, the rotating stirring blade 9 is configured to rotate simultaneously with the rotating stirring shaft 8 during use, thereby completing its stirring function and ensuring thorough mixing of wastewater and reagents. This, combined with illumination, facilitates the wastewater oxidation process. To further enhance mixing efficiency and the device's illumination effect, researchers have incorporated a trapezoidal through-hole 25 and a refractive breaking frame 24 as structural components to supplement the rotating stirring blade 9. As the rotating stirring blade 9 rotates, the wastewater is stirred along with it. Furthermore, the trapezoidal through-hole 25 ensures that the rotating stirring blade 9, while rotating with the rotating stirring shaft 8, effectively facilitates the advanced oxidation process. The device's spliced ​​side plate 3 forms a collision vortex in the internal sewage, thereby amplifying the device's stirring effect. Furthermore, the stirring effect of the rotating stirring blade 9 is further enhanced by the setting of the refractive breaking frame 24. During the stirring process of the rotating stirring blade 9 in the sewage, the edges of the refractive breaking frame 24 can break the water flow and destroy the formed vortex, preventing the formation of multiple vortices in the sewage from affecting its dissolution effect with the oxidant. At the same time, the surfaces of the refractive breaking frame 24, the rotating stirring blade 9, and the trapezoidal through groove 25 are all provided with a reflective coating layer to reflect the light source of the ultraviolet lamp tube 17 at the bottom, refracting the light of the ultraviolet lamp tube 17 as much as possible, and avoiding the existing device from easily absorbing the light, thereby affecting its light efficiency.

[0039] like Figure 1-7 As shown, the ultraviolet lamp tube 17 is also set at the bottom of the spliced ​​base plate 6. A light-transmitting mirror is set at the bottom of the spliced ​​base plate 6. The light-transmitting mirror fits the surface of the spliced ​​base plate 6. The bottom surface of the spliced ​​base plate 6 is coated with a reflective coating. The bottom of the spliced ​​base plate 6 is also provided with a stepped groove. The reflective coating is sealed between the spliced ​​base plate 6 and the light-transmitting mirror. The bottom of the spliced ​​base plate 6 is used to assist in refracting the light emitted by the ultraviolet lamp tube 17. The stepped corners at the bottom and top of the spliced ​​base plate 6 are set in opposite symmetrical configurations.

[0040] In this embodiment, the device is configured in such a way that, when illuminated, the advanced oxidation device's modular side panel 3 effectively forms a sealed chamber based on the number of folded layers. As can be seen, the stepped reflective design of the modular base plate 6 expands the illumination range of the ultraviolet lamp 17 during use. This configuration ensures that even in the absence of sunlight, the modular advanced oxidation device body 1 can still efficiently oxidize the internal wastewater. Furthermore, the bidirectional installation of the ultraviolet lamp 17, in conjunction with the rotating stirring shaft 8 and the bottom modular base plate 6, further reflects the light. Furthermore, under the same light source intensity, the light intensity can be improved. Since the raised parts of the spliced ​​base plate 6 are also coated with reflective material, we can see that the oxidizing reagent near the bottom edge of the spliced ​​base plate 6 not only has no dead angle irradiation area during the oxidation reaction process, but also the irradiation effect at this position is better. Therefore, the researchers have completely solved the problem of dead angle irradiation inside the spliced ​​advanced oxidation device body 1 by setting it up in this way. In addition, the irradiation intensity is also expanded in a certain area by the angle between the raised part of the spliced ​​base plate 6 and the ultraviolet lamp tube 17, thereby ensuring the use effect of the device.
