Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a yellow phosphorus tail gas scrubbing tower with atomized spraying. Background Technology

[0002] The production of yellow phosphorus generates exhaust gases containing various pollutants. These gases must be purified before being released to meet environmental protection requirements. Atomized spray yellow phosphorus exhaust gas scrubbing towers are commonly used industrial exhaust gas treatment equipment. Their core principle is to atomize the scrubbing liquid, allowing for full contact between the gas and liquid. Through physical absorption or chemical reaction, pollutants in the exhaust gas are separated and removed. They play a crucial role in exhaust gas purification and treatment in the yellow phosphorus industry and are one of the key pieces of equipment for ensuring environmental compliance and reducing air pollution.

[0003] Utility model patent CN222624086U discloses a welded large-size scrubbing tower. This welded large-size scrubbing tower includes a scrubbing tower body and a filter screen. The filter screen is fixedly connected to the scrubbing tower body. A rotating shaft is rotatably connected to the scrubbing tower body. A support rod is located on one side of the rotating shaft, with a first brush plate at one end. A second brush plate is located at the top of the rotating shaft. A motor is located at the bottom of the scrubbing tower body and is fixed to the scrubbing tower body with screws. A sludge collection tank is located on the inner bottom of the scrubbing tower body, and a drain pipe is located on one side of the bottom of the scrubbing tower body. A valve is located on one side of the drain pipe. Through the filter screen, rotating shaft, support rod, first brush plate, second brush plate, motor, sludge collection tank, and drain pipe, the device achieves its decontamination function. The brush plates can clean the inner wall of the device, making it more convenient to use. The filter screen can filter the incoming exhaust gas, improving the quality of exhaust gas treatment.

[0004] This welded large-size scrubbing tower does not have a dedicated filtration structure for the spray inlet water. Impurities carried by the spray inlet water can easily enter the spray channel. Moreover, most of the filter components are integrated inside the tower body, requiring the machine to be stopped and disassembled for cleaning, which is a cumbersome operation process. In view of this, we propose an atomized spray yellow phosphorus tail gas scrubbing tower. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5 The atomized spray yellow phosphorus tail gas scrubbing tower includes a tower body 100, a circulating water tank 110, a spray pipe 200, and a sludge removal device 300. The circulating water tank 110 is located at the bottom of the tower body 100 and stores and supplies water for the spraying operation. The spray pipe 200 is connected between the circulating water tank 110 and the top of the tower body 100 to provide a conveying channel for the water flow. The sludge removal device 300 is connected in series with the spray pipe 200 and can intercept impurities in the spray water. The spray pipe 200 is divided into a lower inlet branch pipe 210 and an upper outlet branch pipe 220 by the sludge removal device 300, so as to realize the diversion and conveying of water flow into and out of the sludge removal device 300 respectively.

[0035] like Figures 2-4 As shown, in this utility model, the housing 310 is a hollow cylindrical structure with open ends, providing installation and protection space for internal components. The cover 320 seals the end of the housing 310, both sealing the end of the housing 310 and providing stable support for the rotating shaft 321. The top of the end of the housing 310 has an integrally formed side sleeve 311, providing an independent installation chamber for the gear 322 to prevent damage from contact with water. The cover 320 also seals the end of the side sleeve 311. The bottom of the front end of the housing 310 has an integrally formed collection seat 312, which can collect the scraped impurities. The bottom end of the collection seat 312 is connected to the discharge pipe 313, providing a channel for the discharge of impurities. A valve 314 is installed at the end of the discharge pipe 313, which can control the opening and closing of the discharge pipe 313, facilitating the discharge of impurities as needed. A pair of support plates are fixed to the outer circumference of the casing 310. The ends of the two support plates are fixed to the outer circumference of the tower body 100 by bolts, which can firmly fix the slag cleaning device 300 on the tower body 100 and ensure the reliability of installation. The outer circumference of the casing 310 is also embedded with a viewing window 315, which makes it easy to observe the accumulation of impurities inside the casing 310 and the cleanliness of the filter sleeve 330, and the maintenance time can be determined without disassembly.

[0036] like Figure 2 and Figure 3 As shown, specifically, the filter sleeve 330 extends into the housing 310 from the first end. The filter sleeve 330 has a hollow cylindrical structure with a mesh structure on its outer surface, which can intercept impurities in the sprayed water and allow water to flow through into the branch pipe 220. Its end is closed to prevent unfiltered water from flowing out directly. A fixed end seat 331 at the first end of the filter sleeve 330 not only secures the filter sleeve 330 to the housing 310 but also ensures a tight seal at the connection. The end seat 331 is threaded to the first end of the housing 310, facilitating the disassembly, replacement, and maintenance of the filter sleeve 330.

[0037] like Figure 3 and Figure 5 As shown, the cleaning assembly 340 further includes a rotating seat 341, a collar 342, a scraper 343, and several connecting rods 344. The rotating seat 341 is fitted onto the outer end of the filter sleeve 330, the collar 342 is fitted onto the outer end of the filter sleeve 330, and the scraper 343 is spirally attached to the outer circumferential surface of the filter sleeve 330, which can completely scrape away impurities attached to the surface of the filter sleeve 330 during rotation, preventing impurities from clogging the mesh and affecting the water flow efficiency. The connecting rods 344 are fixed between the outer circumferential surface of the rotating seat 341 and the outer circumferential surface of the collar 342, connecting the rotating seat 341 and the collar 342 into a whole, ensuring synchronicity during rotation, and making the scraper 343 evenly stressed. The rotating seat 341 can drive the collar 342 to rotate circumferentially on the outer side of the filter sleeve 330 through the connecting rods 344, thereby achieving cleaning of the entire circumferential surface of the filter sleeve 330.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, the rotating shaft 321 is rotatably connected to the cover 320, providing a mounting carrier for the gear 322 and transmitting rotational power. The first end of the rotating shaft 321 extends into the side sleeve 311 and is inserted into the side wall of the side sleeve 311. The side sleeve 311 provides support and protection for the first end of the rotating shaft 321. The end of the rotating shaft 321 passes through the cover 320 and is coaxially fixed to the handwheel 323, facilitating manual operation to rotate the rotating shaft 321 and reducing the difficulty of operation. The gear 322 is keyed onto the rotating shaft 321 and is fitted inside the side sleeve 311. The outer circumferential surface of the rotating seat 341 has a toothed groove 3411. The gear 322 meshes with the toothed groove 3411, converting the rotation of the rotating shaft 321 into the circumferential rotation of the rotating seat 341, thus realizing power transmission.

[0039] like Figure 1 and Figure 2As shown, it is worth noting that the top end of the inlet branch pipe 210 passes through the cover seat 320 and is connected to the inside of the casing 310, which can introduce the water flow delivered by the circulating water tank 110 into the casing 310 and filter it by contacting the filter sleeve 330. The bottom end of the outlet branch pipe 220 passes through the end seat 331 and is connected to the inside of the filter sleeve 330, which can deliver the clean water flow filtered by the filter sleeve 330 to the top of the tower body 100 to ensure the cleanliness of the spray water.

[0040] In this embodiment, the atomized spray yellow phosphorus tail gas scrubbing tower operates as follows: First, the spray water in the circulating water tank 110 flows into the casing 310 through the inlet branch pipe 210. As the water flows through the mesh structure of the filter sleeve 330, impurities are intercepted on the outside of the filter sleeve 330. Then, when it is observed through the viewing window 315 that a large amount of impurities have accumulated on the surface of the filter sleeve 330, the handwheel 323 is turned to drive the rotating shaft 321 to rotate. The gear 322 on the rotating shaft 321 meshes with the tooth groove 3411 of the rotating seat 341, driving the rotating seat 341 to rotate circumferentially. Next... The rotating seat 341 drives the collar 342 and the scraper 343 to rotate synchronously via the connecting rod 344. The scraper 343 scrapes away the impurities attached to the surface of the filter sleeve 330. The impurities fall into the collection seat 312 under the action of gravity. Finally, the valve 314 is opened, and the impurities in the collection seat 312 are discharged through the discharge pipe 313. The filtered clean water flows into the filter sleeve 330 and enters the branch pipe 220, and is transported to the top of the tower body 100 to complete the spraying operation. If deep maintenance is required, the end seat 331 can be unscrewed to disassemble the filter sleeve 330 for replacement or thorough cleaning.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
