[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0024] Waste gas is generated during the carbon fiber production process, and a waste gas treatment system is usually configured to treat the waste gas. At present, the main methods for treating carbon fiber waste gas at home and abroad are absorption, combustion, adsorption and catalytic oxidation. Among them, the absorption method uses fillers to absorb harmful substances in the waste gas. Exemplarily, an exhaust gas treatment tower is provided in the exhaust gas treatment system, and 2 to 3 layers of filler layers with different heights are provided in the exhaust gas treatment tower, and each filler layer is provided with multiple fillers, and the filler types include, for example, ball rings, Taylor rosettes and polyhedral hollow balls. The exhaust gas is passed into the exhaust gas treatment tower, and the harmful substances in the exhaust gas are absorbed by the fillers in the exhaust gas treatment tower, thereby achieving the treatment of the exhaust gas.

[0025] Since the packing in the exhaust gas treatment tower needs to be replaced and cleaned after being used for a period of time, in order to ensure the exhaust gas treatment tower's absorption effect on harmful substances in the exhaust gas. For example, the service life of the packing is more than 2 years, and the packing is usually polluted to the extent that it is difficult to absorb harmful substances in the exhaust gas after being used for 2 to 3 months, therefore, within the service life of the packing, the packing can be reused by cleaning it to avoid waste of the packing, and when the packing reaches the end of its service life, the packing can be replaced to ensure the exhaust gas treatment tower's treatment effect on the exhaust gas. However, the poor cleaning effect of the packing in the related art will not only affect the absorption effect of the exhaust gas, but also lead to an increase in the maintenance cost of the exhaust gas treatment system.

[0026] For example, in the related art, multiple cleaning pools are set up to transfer the fillers in the exhaust gas treatment tower to each cleaning pool in turn, thereby achieving the cleaning of the fillers. However, it is difficult to clean the fillers completely and thoroughly by only flushing the fillers with water, resulting in poor cleaning effect on the fillers, affecting the absorption effect of the exhaust gas. At the same time, fillers with poor cleaning effect will also shorten the effective operation time of the exhaust gas treatment system, that is, the fillers need to be cleaned again after a short operation time, which will lead to an increase in the maintenance cost of the exhaust gas treatment system.

[0027] In order to solve the above problems, the present application provides a cleaning system, which is provided with at least one cleaning tank and a wastewater treatment tank. A cleaning device is provided in each cleaning tank. The filler to be cleaned in the cleaning frame is stirred by a first stirring component of the cleaning device. During this process, at least one cleaning brush on the inner wall of the cleaning basket cleans the filler to be cleaned. In this way, the comprehensiveness of the cleaning of the filler to be cleaned can be effectively improved, thereby improving the cleaning effect of the filler to be cleaned, and thus not only improving the absorption effect of the exhaust gas, but also avoiding the shortening of the effective operation time of the exhaust gas treatment system due to poor cleaning effect of the filler, resulting in an increase in the maintenance cost of the exhaust gas treatment system, thereby effectively reducing the maintenance cost of the exhaust gas treatment system; the wastewater after cleaning is discharged into the wastewater treatment tank, and the wastewater discharged into the wastewater treatment tank is treated by the wastewater treatment device. In this way, the pollution of the environment by the wastewater can be avoided, which is beneficial to protecting the environment.

[0028] The cleaning system provided according to the present application is described in detail below in conjunction with the accompanying drawings.

[0029] An exemplary embodiment of the present application provides a cleaning system, such as Figure 1 As shown, the cleaning system 1 includes at least one cleaning tank 11, a wastewater treatment tank 15, at least one cleaning device and a wastewater treatment device. At least one cleaning device is respectively arranged in each cleaning tank 11, and the cleaning device is used to clean the filler to be cleaned placed in the cleaning tank 11. Exemplarily, the cleaning system 1 can be provided with only one cleaning tank 11 or multiple cleaning tanks 11 according to needs. When one cleaning tank 11 is provided, a cleaning device is correspondingly provided, and the cleaning device is provided in the cleaning tank 11; when multiple cleaning tanks 11 are provided, multiple cleaning devices are also correspondingly provided, and each cleaning device is respectively provided in each cleaning tank 11, that is, each cleaning tank 11 is provided with a cleaning device, so that each cleaning device can clean the filler to be cleaned in the cleaning tank 11 where it is located.

[0030] Each cleaning device includes a cleaning basket 12, a first stirring component 13 and at least one cleaning brush 14. The cleaning basket 12 is arranged in the cleaning tank 11, and a plurality of water outlets are arranged on the cleaning basket 12. In this way, when industrial water for cleaning the filler to be cleaned is added to the cleaning tank 11, the industrial water can enter the cleaning basket 12 through the water outlets on the cleaning basket 12 to immerse the filler to be cleaned, thereby cleaning the filler to be cleaned. When the cleaned wastewater is discharged into the wastewater treatment tank 15, the wastewater in the cleaning basket 12 can be discharged through the water outlets. By arranging the water outlets on the cleaning basket 12, it is not necessary to remove the filler when discharging the wastewater in the cleaning tank 11, thereby effectively improving the convenience of cleaning the filler.

[0031] The first stirring component 13 is disposed in the cleaning basket 12, and the first stirring component 13 is used to stir the filler to be cleaned in the cleaning basket 12. At least one cleaning brush 14 is disposed on the inner side wall of the cleaning basket 12. For example, only one cleaning brush 14 may be disposed on the inner side wall of the cleaning basket 12, or a plurality of cleaning brushes 14 may be disposed. When a plurality of cleaning brushes 14 are disposed, the plurality of cleaning brushes 14 may be dispersed on the inner side wall of the cleaning basket 12 along the circumference of the cleaning basket 12.

[0032] By stirring the filler to be cleaned in the cleaning basket 12 through the first stirring component 13, on the one hand, impurities on the filler to be cleaned can be accelerated to fall off, which is beneficial to improve the efficiency and effect of cleaning the filler to be cleaned. On the other hand, in the process of stirring the filler to be cleaned, the filler to be cleaned can be brushed in all directions through each cleaning brush head, so that there is no dead corner in the cleaning of the filler to be cleaned, which effectively improves the comprehensiveness of the cleaning of the filler to be cleaned, thereby further improving the cleaning effect of the filler to be cleaned, and thus can not only improve the absorption effect of the exhaust gas, but also avoid the increase in the maintenance cost of the exhaust gas treatment system due to the shortening of the effective operation time of the exhaust gas treatment system due to the poor cleaning effect of the filler, thereby effectively reducing the maintenance cost of the exhaust gas treatment system.

[0033] The wastewater treatment device is arranged in the wastewater treatment tank 15, and the wastewater after cleaning is discharged into the wastewater treatment tank 15. The wastewater discharged from the cleaning tank 11 into the wastewater treatment tank 15 is treated by the wastewater treatment device, so that the pollution of the environment by the wastewater can be avoided, which is beneficial to protecting the environment. In addition, the cleaning of the filler to be cleaned is realized by cooperating with the wastewater treatment device and the cleaning device. While improving the cleaning effect, it can also effectively improve the degree of automation of the cleaning system 1, thereby effectively improving the convenience of cleaning the filler to be cleaned.

[0034] Combination Figure 1 In one embodiment, an opening is provided at the top of the cleaning pool 11, and the opening is provided to facilitate the addition of industrial water for cleaning the filler to be cleaned into the cleaning pool 11, and to facilitate the placement of the filler to be cleaned in the cleaning basket 12. The cleaning system 1 also includes a cover plate covering the opening, so that the cover plate can be closed during the cleaning process, thereby not only avoiding water splashing, but also effectively improving the safety of the cleaning system 1.

[0035] The first stirring component 13 includes a first rotating shaft 132 and a first driving member 131. The first end of the first rotating shaft 132 extends into the cleaning basket 12, and a plurality of first stirring blades 133 are arranged on the first end of the first rotating shaft 132. The first driving member 131 is arranged on the cover plate, and the first driving member 131 can be, for example, a driving motor, and the first driving member 131 is drivingly connected to the second end of the first rotating shaft 132. The rotation of the first rotating shaft 132 driven by the first driving member 131 drives the rotation of the plurality of first stirring blades 133, thereby achieving stirring of the filler to be cleaned in the cleaning basket 12. With such a design, the structure of the first stirring component 13 is simple and convenient for production and processing.

[0036] In one embodiment, the cleaning device further includes a high-pressure water gun pump, and the water outlet of the high-pressure water gun pump faces the inside of the cleaning basket 12. The filler to be cleaned can be cleaned by the high-pressure water gun pump. For example, after the filler to be cleaned is cleaned by the first stirring component 13 and the cleaning brush 14, the filler can be cleaned for a second time by the high-pressure water gun pump. With such a setting form, the cleanliness of the cleaned filler can be effectively improved, thereby further improving the cleaning effect of the filler to be cleaned.

[0037] Combination Figure 1 In one embodiment, the bottom of the cleaning basket 12 is at a preset distance from the bottom of the cleaning pool 11. The preset distance can be set according to actual needs, for example, it can be 80 mm to 150 mm. With such a design, when impurities in the wastewater settle to the bottom of the cleaning pool 11, by making the bottom of the cleaning basket 12 and the bottom of the cleaning pool 11 at a preset distance, it is possible to avoid the impurities in the wastewater from causing secondary contamination to the cleaned filler, thereby effectively ensuring the cleaning effect of the filler to be cleaned. In addition, when discharging wastewater, by making the bottom of the cleaning basket 12 and the bottom of the cleaning pool 11 at a preset distance, it is possible to avoid the cleaning basket 12 from obstructing the flow of wastewater, thereby improving the smoothness and comprehensiveness of wastewater discharge, and avoiding residual wastewater from causing secondary contamination to the cleaned filler.

[0038] In one embodiment, a plurality of water outlets are disposed at the bottom of the cleaning basket 12, so that the outflow of wastewater is facilitated and the comprehensiveness of the outflow of wastewater can be improved, thereby preventing residual wastewater from causing secondary contamination to the cleaned filler. Exemplarily, the type of filler may include, for example, one of a ball ring, a Taylor rosette, and a polyhedral hollow ball, and the diameter of the filler may be, for example, 18 mm to 65 mm, and the material may be polyethylene, polypropylene, or reinforced polypropylene. Based on this, the diameter of each water outlet is 5 mm to 15 mm. Such a setting is adopted to prevent the filler from leaking out of the water outlet.

[0039] Combination Figure 1In one embodiment, the wastewater treatment device includes a second stirring component 16, which is disposed in the wastewater treatment tank 15 and is used to stir the wastewater discharged into the wastewater treatment tank 15. In this way, it is beneficial to purify the wastewater. For example, the wastewater can be purified by adding alum or other flocculants to the wastewater treatment so that dust or other impurities in the wastewater are precipitated. The second stirring component 16 is provided to stir the wastewater in the wastewater treatment, which helps to fully mix the flocculant with the wastewater, thereby effectively improving the purification effect of the wastewater.

[0040] Combination Figure 1 In one embodiment, the wastewater treatment tank 15 includes a top wall. For example, when an opening is provided at the top of the wastewater treatment tank 15, the top wall can also be formed by a cover plate provided at the opening. The second stirring component 16 includes a second rotating shaft 161 and a second driving member 162. The first end of the second rotating shaft 161 extends into the wastewater treatment tank 15, and a plurality of second stirring blades 163 are provided on the first end of the second rotating shaft 161. The second driving member 162 is provided on the top wall, and the second driving member 162 is drivingly connected to the second end of the second rotating shaft 161. The rotation of the second rotating shaft 161 driven by the second driving member 162 drives the rotation of the plurality of second stirring blades 163, thereby achieving stirring of the wastewater in the wastewater treatment tank 15. With such a design, the structure of the second stirring component 16 is simple and convenient for production and processing.

[0041] Combination Figure 1 In one embodiment, the cleaning system 1 further includes a first valve 101, which is disposed at the bottom of the wastewater treatment tank 15. The first valve 101 is used to open or close the wastewater treatment tank 15. When the impurities in the wastewater are precipitated, the first valve 101 at the bottom of the wastewater treatment tank 15 is opened to discharge the precipitate, and the precipitate can be transported to the drying machine by the transfer vehicle 2 for drying. By disposing the first valve 101 at the bottom of the wastewater treatment tank 15, the discharge of the precipitate is facilitated, and the convenience of removing the precipitate can be effectively improved instead of manually removing the precipitate.

[0042] Exemplarily, the cleaning system 1 further includes a water pump, the water inlet of which is connected to the wastewater treatment tank 15. When the impurities in the wastewater are precipitated, the clear liquid on the upper layer of the precipitate can be transported to a sewage station through the water pump, and after the transportation is completed, the first valve 101 is opened to discharge the precipitate. In this way, the wastewater can be treated, and the pollution of the environment by the wastewater can be avoided, which is beneficial to protecting the environment.

[0043] Combination Figure 1In one embodiment, the cleaning system 1 is provided with a plurality of cleaning pools 11, each of which is connected to the wastewater treatment pool 15 through a connecting pipe 103. The cleaning system 1 also includes a second valve 102 provided on each connecting pipe 103, and the second valve 102 is used to control the on-off of the connecting pipe 103. When the filler to be cleaned is cleaned, the second valve 102 is in a closed state. When the cleaning is completed and the wastewater needs to be discharged, the second valve 102 is opened to discharge the wastewater in the cleaning pool 11 into the wastewater treatment pool 15. Such a setting effectively improves the convenience of discharging wastewater.

[0044] In one embodiment, when cleaning the filler to be cleaned, the filler will frequently rub against the wall of the cleaning tank 11 under the stirring of the first stirring component 13. Based on this, the cleaning tank 11 includes stainless steel parts, which makes the cost performance higher, thereby helping to reduce costs. Exemplarily, the material of the cleaning basket 12 also includes stainless steel parts, which is also helpful to reduce costs.

[0045] In one embodiment, the wastewater treatment tank 15 includes fiberglass parts. Since the fiberglass parts have high corrosion resistance, when the wastewater is treated by the wastewater treatment tank 15 made of fiberglass, it also has a high cost performance, which is conducive to reducing costs.

[0046] Combination Figure 1 In one embodiment, the top wall of the cleaning pool 11 forms a first platform 111, so that personnel can stand on the first platform 111 to manage the cleaning pool 11 and the cleaning device, and to place the filler to be cleaned in the cleaning pool 11.

[0047] Combination Figure 2 When a plurality of cleaning pools 11 are provided, a corridor 112 is further provided between the first platforms 111 on every two cleaning pools 11 , and the corridor 112 constitutes a pedestrian passage to facilitate the passage of personnel between the two cleaning pools 11 .

[0048] Combination Figure 2 In one embodiment, the top wall of the wastewater treatment pool 15 forms a second platform 151. Thus, the second platform 151 can provide a platform for the staff to stand and operate, so as to facilitate their work.

[0049] Combination Figure 1 In one embodiment, the bottom wall of the wastewater treatment tank 15 is recessed downward to form a groove 152, a discharge port 153 is provided at the bottom of the groove 152, and the first valve 101 is provided at the discharge port 153. The diameter of the groove 152 gradually decreases from the notch of the groove 152 to the discharge port 153. With such a setting form, the smoothness of the sediment flowing to the discharge port 153 is improved, and the discharge of the sediment is facilitated.

[0050] In one embodiment, a method for cleaning a filler to be cleaned using the cleaning system 1 includes the following steps:

[0051] The filler to be cleaned is added into the cleaning basket 12 in the cleaning tank 11 .

[0052] In this step, the material of the cleaning pool 11 is 304 stainless steel, the diameter of the cleaning pool 11 is 3000 mm, the height of the cleaning pool 11 is 1000 mm, and the width of the first platform 111 on the outer wall of the cleaning pool 11 is 600 mm; the material of the cleaning basket 12 is 304 stainless steel, the diameter of the cleaning basket 12 is 2700 mm, and the diameter of the water outlet on the bottom of the cleaning basket 12 is 10 mm.

[0053] Close the second valve 102 and add industrial water until the filler to be cleaned is submerged.

[0054] The first driving member 131 is started, so that the filler to be cleaned is continuously cleaned by the cleaning brush 14 in the cleaning basket 12 .

[0055] In this step, the duration of the immersion cleaning varies from 4 hours to 12 hours depending on the degree of contamination of the filler to be cleaned.
