Description

Technical Field

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

[0002] As we all know, during the printing and dyeing process of fabrics, a large amount of wastewater will be generated due to its working sequence, and this wastewater usually contains a variety of chemical components and pollutants;

[0003] Among them, the wastewater generated by fabric printing and dyeing processing is specifically composed of: dyes and pigments, additives, surfactants, heavy metal ions, acid and alkali substances, organic matter, suspended solids, biodegradable substances, etc., which are mixed together to finally constitute the discharged wastewater;

[0004] Although it is difficult to treat wastewater from fabric printing and dyeing, we currently have relatively mature treatment devices for this purpose. After long-term observation, we have found some areas for improvement in the advanced oxidation device used in the wastewater treatment process.

[0005] For example, existing advanced oxidation devices, especially photocatalytic oxidation devices, are often used as independent individuals when in use. It is impossible to measure the amount of sewage output at the work site and it is difficult to use them in a coordinated manner. It is easy to cause waste of production capacity in areas with low sewage output, and it is difficult to fully complete its own production capacity in areas with high sewage output. It is easy for a single device to process multiple times, which greatly reduces the oxidation efficiency of the device.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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 creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] The following is combined with Figure 1-7 The present invention is described in further detail.

[0030] See also Figure 1-7 The present invention provides a technical solution: an advanced oxidation device for deep treatment of fabric printing and dyeing wastewater, such as Figure 1-7As shown, the device comprises a spliced ​​advanced oxidation device body 1, a top cover 2 of the spliced ​​advanced oxidation device body 1 is arranged on the top, a device water inlet 4 is opened on the upper side of the spliced ​​advanced oxidation device body 1, a device water outlet 5 is opened on the lower side of the spliced ​​advanced oxidation device body 1, and a spliced ​​side plate 3 of the advanced oxidation device is arranged inside the spliced ​​advanced oxidation device body 1. The spliced ​​advanced oxidation device body 1 is specifically composed of a plurality of spliced ​​side plates 3 of the advanced oxidation device spliced ​​together, and the device water inlet 4 and the device water outlet 5 are both spliced ​​advanced oxidation device side plates. The spliced ​​side plate 3 is disassembled to form a structure in which a spliced ​​bottom plate 6 is arranged inside the spliced ​​side plate 3 of the advanced oxidation device, and the spliced ​​bottom plate 6 forms the bottom and top of the spliced ​​side plate 3 of the advanced oxidation device during splicing, and a catalyst sheet placement soft plate 7 is arranged on the upper surface of the spliced ​​bottom plate 6, and a rotating stirring shaft rod 8 is arranged inside the spliced ​​side plate 3 of the advanced oxidation device, and a rotating stirring shaft blade 9 is inserted on the surface of the rotating stirring shaft rod 8, and a plurality of notches for the rotating stirring shaft blade 9 to be inserted are provided on the surface of the rotating stirring shaft rod 8, and a stirring guide is provided on the surface of the rotating stirring shaft rod 8 in a spiral manner Ring 10, a water flow opening 11 is provided inside the body 1 of the spliced ​​advanced oxidation device, and the water flow opening 11 is specifically formed by splicing the spliced ​​side panels 3 of the advanced oxidation device, and a mosaic positioning guide shaft 12 is movably connected to one side of the spliced ​​bottom plate 6 near the water flow opening 11, and the surface of the mosaic positioning guide shaft 12 is fixedly connected to the catalyst sheet placement soft plate 7, and the mosaic positioning guide shaft 12 is used to roll up the catalyst sheet placement soft plate 7 covering the top of the spliced ​​bottom plate 6. Now let's simply expand the various parts described above. First of all, it should be noted that the spliced The structure of the advanced oxidation device body 1 itself is formed by splicing several advanced oxidation device splicing side panels 3, and in the process of splicing the advanced oxidation device splicing side panels 3, they can be used cumulatively and superimposed with reference to the working environment. Here, the use background is described in detail. The device is a link device for the entire sewage deep treatment, a pre-equipment of the advanced oxidation equipment, and the sewage needs to be pre-treated. The device is located in the three-stage treatment link of the entire sewage treatment link. The first-stage treatment link is primary treatment; it is intended to remove large suspended particles and solid matter in sewage;The secondary treatment link is secondary treatment, which aims to remove soluble organic matter and some suspended matter in sewage, and degrade organic pollutants in sewage through biochemical processes. The tertiary treatment link is deep treatment, which aims to further remove the remaining pollutants in sewage and achieve higher water quality standards, especially the removal of nutrients such as nitrogen and phosphorus. On this basis, the sewage in the front link can be connected to the device, and enter the interior of the spliced ​​advanced oxidation device body 1 through the device water inlet 4, and the sewage is oxidized by the spliced ​​side plate 3 of the advanced oxidation device. In the above process, when the sewage enters the interior of the spliced ​​side plate 3 of the advanced oxidation device, it is preferentially retained therein. At this time, the user can start the rotating stirring shaft 8, so that the rotating stirring shaft 8 starts to rotate, and the rotating stirring shaft 8 is driven to rotate the rotating stirring shaft blade 9 during the rotation process. It should be noted that during the rotation of the rotating stirring shaft 8, the stirring guide ring 10 opened on the surface of the rotating stirring shaft 8 will rotate simultaneously with the rotation of the rotating stirring shaft 8, and since the stirring guide ring 10 is The spiral shape is opened on the surface of the rotating stirring shaft 8. During the rotation of the rotating stirring shaft 8, due to the centrifugal force of the high-speed rotation, a layer of air explosion floating film will be brought up on the surface of the rotating stirring shaft 8. In this way, the stirring guide ring 10 can increase the stirring effect of the rotating stirring shaft 8 itself, so that the internal sewage of the spliced ​​advanced oxidation device body 1 can be better contacted with the catalyst on the surface of the catalyst sheet placement soft plate 7 during the stirring process of the rotating stirring shaft 8, and in the process of contact, different watersheds can be replaced, so that the watershed can be better exposed to the light source, thereby improving the oxidation reaction efficiency of the sewage; and, through the setting of the catalyst sheet placement soft plate 7 and the embedded positioning guide shaft 12, it is ensured that the catalyst sheet placement soft plate 7 itself can be more effectively rolled up and replaced during the use of the device, ensuring that the cleaning process of the device does not need to be as complicated as the previous device. The user only needs to directly roll up the catalyst sheet placement soft plate 7 through the embedded positioning guide shaft 12, so as to replace it, ensuring the use and replacement efficiency of the device;

[0031] The surface of the catalyst sheet placement soft board 7 is installed with ultraviolet lamp tubes 17. The ultraviolet lamp tubes 17 are diagonally arranged and installed on the surface of the catalyst sheet placement soft board 7. The catalyst sheet placement soft board 7 can be disassembled and assembled and installed above the spliced ​​bottom plate 6. The inside of the catalyst sheet placement soft board 7 is provided with a connecting slot 15. The inside of the connecting slot 15 is provided with a connecting positioning belt 16. The connecting positioning belt 16 is used to combine and connect the catalyst sheet placement soft board 7. The inside of the catalyst sheet placement soft board 7 is connected with a positioning pull-out rod 13. The positioning pull-out rod 13 is also connected to the inside of the embedded positioning guide shaft 12. The end of the positioning pull-out rod 13 close to the embedded positioning guide shaft 12 is provided with a positioning convergence bottom ring 14. The bottom ring 14 is used to close and fix the positioning pull rod 13. The spliced ​​bottom plate 6 is opened in a stepped shape. A friction positioning plate 18 is arranged on the surface of the spliced ​​bottom plate 6. An engaging clamping rod 19 is arranged on the side of the spliced ​​bottom plate 6 close to the engaging positioning guide shaft 12. The surface of the engaging clamping rod 19 is sleeved with a placement guide rod 20. It should be emphasized that the position of the placement guide rod 20 close to the front end ring is extremely thin 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, thereby avoiding the normal setting and use of the rotating stirring shaft 8. It should also be emphasized that the spliced ​​bottom plate 6 itself is arranged in a stepped shape, but in order to avoid sewage residue, In order to ensure that the spliced ​​bottom plate 6 itself can be easily cleaned by users, all the step connections of the spliced ​​bottom plate 6 are set to rounded corners, thereby ensuring that the silt water can be discharged normally without being retained. Similarly, the spliced ​​bottom plate 6 is based on the length axis. During the manufacturing process, the spliced ​​bottom plate 6 itself is in a state of high in the middle and low on both sides, thereby ensuring that the device can quickly drain water from the side, thereby not affecting the use of the device. At this time, we need to further explain the placement of the soft plate 7 for placing the catalyst sheet. During the use of the device, since the device itself can be in a spliced ​​state, its convenience is given priority. By positioning the pull rod 13 and the interlocking positioning guide The shaft 12 is bound, and the positioning and pulling rod 13 can directly penetrate the catalyst sheet placement soft plate 7 during the process of binding the advanced oxidation device top cover 2. Therefore, when the device is closed, we only need to pull it upwards, that is, the entire catalyst sheet placement soft plate 7 can be pulled up, and then pulled backward, so that the embedded positioning guide shaft 12 and the catalyst sheet placement soft plate 7 can be directly closed, thereby effectively ensuring the disassembly and cleaning effect of the device. If in the placement process, we only need to rewind the cleaned catalyst sheet placement soft plate 7 first, and then through the guidance of the placement guide rod 20, the embedded positioning guide shaft 12 can be reset, so that the device can continue to be used.

[0032] In this embodiment: It should be emphasized that the spliced ​​bottom plate 6 itself can also be used as an independent device. We can see that the rotating stirring shaft 8 has been conceived to be used as a spliced ​​device at the beginning of the design, that is, multiple rotating stirring shafts 8 are mounted and used coaxially. It can be seen that the spliced ​​advanced oxidation device body 1 is an independent device in the figure, with a foldable height and a device water outlet 5 and a device water inlet 4. However, if the company has already made an open-air large-scale exposure pool device in advance, it only needs to unpack the spliced ​​bottom plate 6. It is laid on the bottom of the pool, and a support frame for supporting the rotating stirring shaft 8 is provided between the two spliced ​​bottom plates 6 by connecting the rotating stirring shaft 8 through the coaxial one. The rotating stirring shaft 8 can still be driven by the driving source, and the rotation principle of the rotating stirring shaft 8 is equivalent to that of an ordinary rotating shaft. In order to facilitate the user to replace the reagent, we can also connect the embedded positioning guide shaft 12 in series as a coaxial one, so as to converge them together, so as to ensure the working efficiency of the spliced ​​bottom plate 6. Therefore, we propose it here as a method of using the present device.

[0033] like Figure 1-7 As shown, one end of the guide rod 20 is placed in contact with the inner wall of the spliced ​​side plate 3 of the advanced oxidation device, and the inner wall of the spliced ​​side plate 3 of the advanced oxidation device is provided with a load-bearing groove for supporting the guide rod 20. Both sides of the spliced ​​bottom plate 6 close to the spliced ​​side plate 3 of the advanced oxidation device are provided with soft materials for sealing the spliced ​​bottom plate 6, and the soft materials can be removed. The four walls of the spliced ​​side plate 3 of the advanced oxidation device are all semi-hollow. The inner wall of the spliced ​​side plate 3 of the advanced oxidation device is provided with a card interface for installing the rotating stirring shaft 8, and the inner wall of the spliced ​​side plate 3 of the advanced oxidation device is also provided with a plug-in groove for installing the embedded card rod 19.

[0034] In the present embodiment, one point that needs to be elaborated is that, during the use of the placement guide rod 20, the main stress point is supported by the spliced ​​side plate 3 of the advanced oxidation device, and at the same time, the inside of the load-bearing groove supported by the placement guide rod 20 is filled with fillers to seal the connection between the spliced ​​side plate 3 of the advanced oxidation device and the placement guide rod 20 to prevent sewage from entering and causing corrosion during the entry process. At the same time, the thinner part of the connection between the placement guide rod 20 and the embedded clamping rod 19 makes it possible to effectively disassemble the placement guide rod 20 itself when the placement guide rod 20 is used in conjunction with the spliced ​​side plate 3 of the advanced oxidation device, and it is also convenient for the placement guide rod 20 to be removed from the inside of the spliced ​​side plate 3 of the advanced oxidation device. At the same time, referring to the content in the above embodiment, when the spliced ​​bottom plate 6 is used as an independent device in the exposure pool, the placement guide rod 20 can be disassembled. At the same time, the embedded clamping rod 19 can penetrate left and right to complete the splicing. The local fixing effect of the spliced ​​bottom plate 6 in the horizontal splicing can be seen. Moreover, it can be seen that the catalyst sheet placement soft plate 7 is placed on the surface of the spliced ​​bottom plate 6 during use, and the spliced ​​bottom plate 6 is used as a whole support, while the spliced ​​bottom plate 6 is divided into two parts for use. When it is installed inside the spliced ​​side plate 3 of the advanced oxidation device and used as a single local component, it is supported laterally by non-directly overlapping one side of the inner wall of the spliced ​​side plate 3 of the advanced oxidation device. During this process, the bottom of the spliced ​​bottom plate 6 on the side of the water flow outlet 11 should be installed with a bracket for abutting or supporting it, so as to assist the installation of the spliced ​​bottom plate 6, so that the spliced ​​bottom plate 6 can be clamped and fixed by the spliced ​​side plate 3 of the advanced oxidation device on not only three sides. Therefore, it is arranged in this way to ensure that the spliced ​​bottom plate 6 can be disassembled as an independent device without affecting the stability of the spliced ​​bottom plate 6 in the spliced ​​side plate 3 of the advanced oxidation device.

[0035] like Figure 1-7 As shown, a light strip fitting rod 21 is provided inside the ultraviolet lamp tube 17, and an ultraviolet light strip is inserted and connected inside the light strip fitting rod 21, and the light strip fitting rod 21 is made of a light-transmitting material. The ultraviolet lamp tube 17 is provided with six sides, and a side diffusion lens 22 is provided on the side of the ultraviolet lamp tube 17, and the side diffusion lens 22 is provided on the four sides of the ultraviolet lamp tube 17 and is symmetrically installed, and a forward refractive lens 23 is provided on the top and bottom of the ultraviolet lamp tube 17, and the bottom angle of the forward refractive lens 23 does not exceed 90°. Specifically refer to the formula n1sinθ1=n2sinθ2, wherein n1 and n2 are the refractive indices of the medium, θ1 is the incident angle, and θ2 is the refraction angle. At the same time, refer to the formula divergence angle=2arctan(2LD), wherein D is the diameter of the light source, and L is the distance from the light source to the target surface, and the coverage radius of the ultraviolet lamp tube 17 is matched;

[0036] In this embodiment, through the introduction of the above formula, we can find that the installation of the ultraviolet lamp 17 is also installed in a right-angle progressive manner on the surface of the catalyst sheet placement soft board 7, referring to Figure 4 From the detailed introduction of FIG. 1 , we can see that, with this installation method, while ensuring the irradiation coverage radius of the ultraviolet lamp tube 17, the two sections of the ultraviolet lamp tube 17 can be combined and irradiated by themselves, thereby forming a common irradiation area, thereby greatly improving the irradiation range under the same irradiation length, and the ultraviolet lamp tube 17 is hexagonal for irradiation angle structure, which can more effectively expand its irradiation angle range. It can be seen that we set the side diffuse lens 22 to a convex lens structure, and its curvature refers to the above formula. The light inside the ultraviolet lamp tube 17 should be divided, thereby scattering the light source, and the ultraviolet lamp tube 17 inside The light source has three irradiation directions, namely upward irradiation. Through the setting of the forward refractive lens 23, the light is diffused while being refracted, and reflected in conjunction with the other devices to achieve the highest irradiation efficiency under the condition of the lowest irradiation intensity, or irradiation is performed obliquely upward. The side diffuse lens 22 can assist the forward refractive lens 23 in irradiation while also irradiating the light source downward, irradiating the area downward to form an overlapping irradiation area, and through the side diffuse lens 22 set obliquely below the ultraviolet lamp tube 17, the surface of the catalyst sheet on which the soft board 7 is placed is covered with a catalyst for photocatalysis, thereby greatly improving the coordinated oxidation reaction efficiency of the device.

[0037] like Figure 1-7 As shown, a trapezoidal through groove 25 is provided inside the rotating stirring shaft blade 9, and the trapezoidal through groove 25 is set to be wide at the front and narrow at the back. Refraction and crushing frames 24 are provided on both sides of the rotating stirring shaft blade 9, and the bottom of the refraction and crushing frames 24 is opened with rounded corners, and the top of the refraction and crushing frames 24 is opened at a right angle. The opening directions of the refraction and crushing frames 24 and the trapezoidal through groove 25 match the rotation direction of the rotating stirring shaft blade 9;

[0038] In this embodiment, by setting the rotating stirring blade 9 in this way, the rotating stirring blade 9 can rotate simultaneously with the rotating stirring shaft rod 8 during use, thereby completing its own stirring function, so that the sewage can be fully mixed with the reagent, and at the same time, cooperate with the light to complete the sewage oxidation operation process. However, in order to increase the mixing efficiency and enhance the lighting effect of the device itself, the researchers specially set up a trapezoidal through groove 25 and a refractive fragmentation frame 24 as structural supplements of the rotating stirring blade 9 itself. It can be seen that when the rotating stirring blade 9 is rotating, the sewage will be stirred along with the rotating stirring blade 9 itself, and through the setting of the trapezoidal through groove 25, the rotating stirring blade 9 will be stirred in the process of following the rotating stirring shaft rod 8 to rotate and stir during the advanced oxidation process. Colliding vortices are formed in the sewage inside the spliced ​​side panels 3 of the device, thereby expanding the stirring effect of the device, and the stirring effect of the rotating stirring blades 9 can be further enhanced by setting the refractive breaking frame 24. When the rotating stirring blades 9 are placed in the sewage for stirring, the corners of the refractive breaking frame 24 can cut the water flow and destroy the formed vortex, thereby avoiding the formation of multiple vortices in the sewage to affect the dissolution effect of the oxidant. At the same time, the surfaces of the refractive breaking frame 24, the rotating stirring blades 9 and the trapezoidal through grooves 25 are all provided with a reflective coating layer, which is used to reflect the light source of the ultraviolet lamp 17 at the bottom, refract the light of the ultraviolet lamp 17 as much as possible, and avoid the existing device from easily absorbing its light, thereby affecting its lighting efficiency.

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

[0040] In this embodiment, by such an arrangement, when the device is irradiating light, the spliced ​​side panels 3 of the advanced oxidation device itself can be effectively formed into a sealed room according to the number of folded layers. It can be seen that by the stepped reflective arrangement of the spliced ​​bottom plate 6, the illumination range of the ultraviolet lamp 17 can be expanded during use. Such an arrangement ensures that in a room without sunlight, the spliced ​​advanced oxidation device body 1 can still efficiently oxidize the internal sewage, and the ultraviolet lamp 17 is installed in a two-way manner, and can cooperate with the rotating stirring shaft 8 and the spliced ​​bottom plate 6 at the bottom to reflect light. Furthermore, under the effect of the same light source intensity, the light intensity can be improved, and because the raised position of the spliced ​​bottom plate 6 is also coated with reflective material, we can find that during the oxidation reaction of the oxidizing reagent near the bottom edge of the spliced ​​bottom plate 6, not only there is no dead angle irradiation area, but also the irradiation effect at this position is better.
