Description
Technical Field
[0001] The utility model relates to the technical field of flue gas dust removal, in particular to a flue gas dust removal system for solid waste treatment. Background Art
[0002] Incineration of solid waste involves oxidizing the combustible materials in the solid waste through combustion, achieving volume reduction and utilizing its thermal energy. However, incineration produces a large amount of smoke and dust, which needs to be processed before being released into the atmosphere to reduce pollution. Some dust removal equipment is equipped with ceramic fiber filter tubes, which can block dust on the outer surface, allowing nitrogen oxides and ammonia to enter. The interior is impregnated with catalysts, which promote the reaction and reduction of ammonia to harmless nitrogen and water. Some existing flue gas dust reduction equipment passes through the flue gas quickly. Although spray structures are provided, the interaction time is too short, resulting in poor dust reduction effect on the flue gas. In addition, some filter structures are internal to the equipment, requiring manual cleaning after disassembly and cleaning, which is labor-intensive and inconvenient. Utility Model Content

[0043] In this embodiment, the scraper 142 is made of polyphenylene sulfide (PPS). PPS is an engineering plastic with excellent chemical resistance, wear resistance and high temperature resistance.

The positioning rods 145 pass through the fixed frame 144 and are fixedly connected thereto, and a return spring 146 is fixedly connected between the positioning rods 145 and the fixed frame 144.
[0045] During specific implementation, the two limit rods 14 are synchronously connected through the fixed frame 144, and the sliding limit in the vertical direction is performed by the positioning rod 145. The fixed frame 144 can be driven to reset by the reset spring 146, so that after the spiral frame 12 rotates to squeeze the scraper 142, the subsequent reset spring 146 can drive multiple scrapers 142 to automatically move back to their original position, so that the scraper 142 can remain in contact with the bottom of the spiral frame 12.
[0046] Example 2
[0047] On the basis of the first embodiment, in order to facilitate the synchronous automatic cleaning of the exterior of multiple ceramic fiber filter tubes 161 .

A plurality of nozzles 131 all pass through the treatment cylinder 10 and are fixedly connected to the mounting pipe 13. The outer wall of the treatment cylinder 10 is connected to the air supply pipe 101, and the bottom of the treatment cylinder 10 is fixedly connected to the sewage pipe 102. The auxiliary module 17 includes a cleaning plate 171, and the cleaning plate 171 is slidably connected to the inside of the sewage shell 16. A plurality of ceramic The fiber filter tubes 161 all pass through the cleaning plate 171, the fixing frame 172 is slidably connected to the inside of the sewage shell 16, the fixing frame 172 passes through the sewage shell 16 and is fixedly connected to the cleaning plate 171, the electric push rod 173 is fixedly connected to the outer wall of the sewage shell 16, and the output end of the electric push rod 173 is fixedly connected to the fixing frame 172.

One end of the water supply pipe 174 is fixedly connected to the connecting pipe 132, and the other end of the water supply pipe 174 is fixedly connected to the adjacent nozzle 175.
[0049] During specific implementation, the nozzles 131 are fixed and installed through multiple installation pipes 13, and water can be supplied to the interior of the multiple nozzles 131 through the connecting pipes 132. Water is sprayed into the interior of the treatment tube 10 through the multiple nozzles 131. The smoke enters the interior of the treatment tube 10 through the air supply pipe 101 and climbs along the spiral frame 12. The nozzles 131 can spray water to reduce the upward smoke, and the sewage flows downward along the top of the spiral frame 12 and is discharged through the sewage pipe 102. After the ceramic fiber filter tube 161 has been used for a period of time, a lot of impurities are attached to its exterior. Starting the electric push rod 173 can drive the fixing frame 172 to drive the cleaning The cleaning plate 171 moves downward, and the outside of the multiple ceramic fiber filter tubes 161 is scraped by the cleaning plate 171, thereby achieving physical cleaning, ensuring a certain filtering effect of the ceramic fiber filter tubes 161, and thus optimizing the dust removal effect. When water is supplied to the inside of the installation tube 13 through the connecting pipe 132, water is simultaneously supplied to the two nozzles 175 through the water supply pipe 174. The two nozzles 175 spray water to form a layer of water film, which reduces dust in the passing air again, and when the cleaning plate 171 moves down to the lowest point, it will contact the water film, so that the cleaning plate 171 can be flushed, and the debris can be flushed down and discharged to the outside through the spiral rack 12 and the sewage pipe 102.
