Description

Technical Field

[0001] This utility model relates to the technical field of flue gas purification and treatment, specifically to a flue gas purification and treatment device for ceramsite sintering. Background Technology

[0002] In the production of ceramsite, rotary kiln sintering is one of the core processes. However, this process generates a large amount of high-temperature flue gas containing pollutants such as dust, sulfur oxides, nitrogen oxides, fluorides, hydrogen chloride, and potentially heavy metals and dioxins. If these pollutants are discharged directly without effective treatment, they will cause serious pollution to the atmospheric environment, endanger human health, and may violate increasingly stringent environmental regulations.

[0003] A rotary kiln denitrification and dust removal integrated device, as disclosed in CN202322252686.0, includes a shell, a base at the bottom of the shell, a water chamber inside the shell, a bend inside the water chamber, an air outlet pipe outside the bend, a first water pump outside the shell, an outlet pipe and a drain pipe outside the first water pump, an inlet pipe outside the shell, a purification chamber inside the shell, a recovery tank at the bottom of the inner side of the purification chamber, a second water pump outside the shell, an inlet pipe and an outlet pipe outside the second water pump, and a spray plate outside the outlet pipe. This rotary kiln denitrification and dust removal integrated device can simultaneously denitrify and remove dust from the flue gas discharged from the rotary kiln, recover the waste heat of the flue gas, and reuse the denitrification solution, thereby improving ease of use. Furthermore, the integrated design significantly reduces the size of the device.

[0004] The rotary kiln denitrification and dust removal integrated device proposed in the above patent can achieve cooling, denitrification, filtration and purification of flue gas before discharge. However, it lacks a component for scraping the filter plate during the recovery of denitrification solution, which easily leads to impurities clogging the filter holes on the filter plate, thereby affecting the filtration recovery rate. In addition, it also lacks a component for disassembling and assembling the activated carbon plate, resulting in a long-term impact on the effect of flue gas filtration and purification.

[0005] Therefore, we propose a sintering and flue gas purification device for ceramsite to solve the problems mentioned above. Utility Model Content

The coolant added to the purification box 1 can cool and lower the flue gas flowing in the serpentine pipes 40. After cooling, the flue gas is discharged above the recovery tank 7, at which point the suction pump 10 can be started. During operation, it will draw the denitrification solution spray from the recovery tank 7 and spray it out through the spray plate 20, thus spraying the flue gas to achieve denitrification and dust removal. The purified flue gas is filtered by the activated carbon filter plate 3 and discharged to the outside of the purification box 1 through the exhaust pipe 2. The denitrification solution sprayed by the nozzles... After the flue gas undergoes denitrification and dust removal, the solution falls onto the filter screen plate 8 under gravity. After filtration, it flows into the recovery tank 7 and can be re-pumped and reused by the suction pump 10. In addition, the servo motor 92 can be activated during flue gas treatment. When the servo motor 92 is running, it drives the threaded rod 93 to rotate. When the threaded rod 93 rotates, it drives the threaded sleeve 94 to move back and forth. When the threaded sleeve 94 moves back and forth, it drives the adjacent moving rod 96 to move back and forth through the connecting plates 95 on both sides. When the moving rod 96 moves back and forth, it drives the scraper 97 to move back and forth on the filter screen plate 8, which can scrape and push the impurities on it back and forth, avoiding the impurities from clogging the filter holes and thus affecting the efficiency of solution recovery.

[0038] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-4 and Figure 8 The snap-fit ​​assembly 5 includes L-shaped support plates 51 located on the left and right sides of the mounting plate 4 near the front. The opposite sides of each L-shaped support plate 51 are fixedly mounted on the outer wall of the purification chamber 1. Each L-shaped support plate 51 has a threaded tube 52 that is movably installed through it. The inner cavity of each threaded tube 52 is threaded with a screw 53 extending to the outside. The opposite end of each screw 53 is fixedly mounted with a sliding plate 54. The opposite side of each sliding plate 54 has several positioning rods 55 fixedly mounted at equal intervals. The mounting plate 4 has evenly spaced openings near the front. Several positioning holes are provided, and the output ends of the positioning rods 55 extend into the inner cavities of adjacent positioning holes. A snap-fit ​​plate 56 is provided on the lower side of the opposite side of the sliding plate 54. The rear side of the snap-fit ​​plate 56 is fixedly installed on the recycling tank 7. An L-shaped snap-fit ​​rod 57 is slidably installed on the snap-fit ​​plate 56. The lengths of the L-shaped snap-fit ​​rods 57 on both sides are different, but the effect is the same. The upper ends of the L-shaped snap-fit ​​rods 57 are fixedly installed on the adjacent sliding plates 54, which can realize the disassembly, removal, cleaning or replacement of the activated carbon filter plate 3 and the filter screen plate 8.

[0041] In this embodiment: When the activated carbon filter plate 3 and the filter screen plate 8 are used for a long time, they can be disassembled and replaced. By rotating the knobs 521 on both sides, the adjacent threaded tube 52 will be rotated. When the threaded tube 52 rotates, the adjacent sliding plate 54 will be moved in the opposite direction through the screw 53. When the sliding plate 54 moves in the opposite direction, the adjacent positioning rod 55 will be moved outward, thus moving away from the inner cavity of the adjacent positioning hole. At the same time, the adjacent L-shaped locking rod 57 will be moved away from the adjacent locking plate 56. At this time, the locking of the mounting plate 4 and the recovery tank 7 can be released. Then, by pulling outward, the activated carbon filter plate 3 and the filter screen plate 8 can be taken out. After cleaning or replacement, the reverse operation can be performed to re-lock them. During disassembly, denitrification solution can also be added to the inner cavity of the recovery tank 7, which is conducive to the resumption of flue gas treatment.
