[0039] The present invention provides a technical solution:

[0040] Please refer to Figures 1 to 9 , a device for treating the regenerated waste liquid of SCR denitration catalyst, which includes an outer cylinder 1 and an upper connecting ring 11 fixedly installed on the outer side of the outer cylinder 1, and a filtering mechanism 2 is arranged on the inner wall of the outer cylinder 1.

[0041] The filtering mechanism 2 includes a mounting ring 21, a filtering component 22 is movably installed on the top of the mounting ring 21, a clogging prevention component 23 is connected by bearing at the center inside the filtering component 22, and a connecting cylinder 24 is fixedly installed at the lower end of the clogging prevention component 23. Through the design of the mounting ring 21, the filtering component 22, the clogging prevention component 23 and the connecting cylinder 24, the effective filtering and clogging prevention of solid impurities in the regenerated waste liquid of SCR denitration catalyst are realized, ensuring the smooth progress of the filtering process and improving the purity and quality of the waste liquid.

[0042] The filtering component 22 includes a filter screen mounting frame 221 movably installed on the top of the mounting ring 21.

Through the movably installed filter screen mounting frame 221 and the filter screen 222 fixed thereon, effective filtration of solid impurities in the waste liquid is achieved; the design of the counterweight 224 promotes the asynchronous rotation of the filter screen 222 and the cleaning rod 232, effectively preventing blockage and ensuring smooth filtration. The design of the range limiting cylinder 223 can limit the range of the waste liquid.

[0043] The anti-blocking component 23 includes a shaft rod 231 connected to the inner center of the filter screen mounting frame 221 by a bearing. A cleaning rod 232 is fixedly installed on the outer side of the shaft rod 231. The lower end of the cleaning rod 232 contacts the filter screen 222.

[0044] Furthermore, the outer diameter of the filter screen mounting frame 221 is larger than the inner diameter of the mounting ring 21.

[0046] Furthermore, the output end of the servo motor 32 penetrates through the top cover 31 and is fixedly connected to the upper end of the shaft rod 231. By having the output end of the servo motor 32 penetrate through the top cover 31 and be connected to the shaft rod 231, this design enables the servo motor 32 to directly drive the anti-blocking component of the filtering mechanism 2 to rotate, thereby effectively cleaning the filter screen 222, preventing blockage, ensuring smooth filtration, and improving the waste liquid treatment efficiency.

At the same time, through the design of the heat preservation cylinder 42 and the discharge valve 46, the stability and convenience of the treatment process are ensured.

[0048] Further, both the outer cylinder 1 and the heat preservation cylinder 42 are made of heat preservation materials.

At the same time, the vibration motor 53 drives the activated carbon adsorption plate 525 to vibrate, removing dust and impurities and ensuring the purification effect. The collection box 526 is convenient for subsequent cleaning, reflecting the environmental protection and practical design concepts.

[0052] Furthermore, a support mechanism 6 is provided at the bottom of the stirring mechanism 4. The support mechanism 6 includes support foot rods 61 fixedly installed at the bottom of the heat preservation cylinder 42. Support foot seats 62 are fixedly installed at the bottoms of the support foot rods 61. An electric telescopic rod 63 is fixedly installed on one side of the top of the support foot seat 62 far from the support foot rod 61. Through the support foot rods 61, the support foot seats 62 and the electric telescopic rod 63, stable support is provided, enhancing the flexibility and practicality of the equipment.

[0053] During specific use, the working principle of the present invention is as follows:

[0054] When using this waste liquid treatment device, first start the servo motor 32. The servo motor 32 drives the shaft rod 231 to rotate through its output end. The rotation of the shaft rod 231 further drives the cleaning rod 232 to rotate. The lower end of the cleaning rod 232 contacts the filter screen 222, thereby cleaning the filter screen 222. Since a counterweight 224 is fixedly installed at the top of the filter screen mounting frame 221, during the rotation process, due to the action of centrifugal force, the filter screen mounting frame 221 and the filter screen 222 generate an asynchronous rotational movement relative to the cleaning rod 232. This asynchronous rotational movement not only helps to accelerate the filtration speed of solid impurities in the waste liquid, but also effectively prevents the waste liquid from clogging the filter holes of the filter screen 222, ensuring the smooth progress of the filtration process.

[0055] At the same time, add the SCR denitration catalyst regeneration waste liquid from the feed bin 33 into the outer cylinder 1. Under the action of gravity, the waste liquid flows through the filtering mechanism 2 installed on the inner wall of the outer cylinder 1. The filter screen 222 filters the waste liquid, separating the solid impurities therein and improving the purity of the waste liquid in the subsequent treatment process.

[0056] The filtered waste liquid flows into the stirring mechanism 4. Under the driving action of the connecting cylinder 24 and the connecting column 454, the stirring member 45 starts to rotate. The inclined rod 453 at the upper end of the stirring member 45 crushes and stirs the waste liquid. At the same time, the inclined design of the inclined rod 453 causes the waste liquid to move downward. The bolt conveyor rod 455 at the lower end of the stirring member 45 transports the waste liquid at the bottom of the heat conduction cylinder 441 upward, forming a turning effect to ensure that the waste liquid is fully mixed and treated in the stirring mechanism 4.

[0057] In order to maintain the optimal treatment temperature, the temperature sensor 443 monitors the temperature in the heat conduction cylinder 441 in real time and feeds back the signal to the control system as needed. The control system adjusts the heating power of the heating resistance wire 442 according to the preset temperature range, thereby achieving precise control of the waste liquid treatment temperature.

[0058] During the waste liquid treatment process, the generated tail gas enters the tail gas purification mechanism 5 through the exhaust end of the outer cylinder 1. The tail gas first enters the purification box group 52, and the activated carbon adsorption plate 525 highly adsorbs the harmful substances in the tail gas to ensure that the tail gas emission meets the environmental protection standards. In order to prevent the activated carbon adsorption plate 525 from being clogged by dust and affecting the adsorption effect, the vibration motor 53 is started regularly. Under the synergistic action of the movable plate 541, the second spring 542 and the support 543, the purification box group 52 generates vibration, driving the activated carbon adsorption plate 525 inside it to vibrate repeatedly, effectively removing the dust and impurities attached to the surface of the activated carbon.

[0059] In addition, during the vibration process, the collection box 526 is located under the activated carbon adsorption plate 525. The collection box 526 is convenient for collecting the dust and impurities falling from the activated carbon adsorption plate 525, facilitating subsequent cleaning.

[0060] Through reasonable structural design and working process, the whole device realizes the efficient treatment and resource utilization of the SCR denitration catalyst regeneration waste liquid, reduces environmental pollution, and has good economic and social benefits.

[0061] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made on the basis of the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
