Description
Technical Field
[0001] This utility model relates to the field of flue gas purification technology, and more specifically, to a flue gas purification device based on a hot raw material cement kiln. Background Technology
[0002] Flue gas purification devices based on hot raw material cement kilns are designed to treat and purify the waste gas generated during cement production. Cement production, especially in kilns utilizing hot raw materials (such as waste materials, alternative fuels, etc.), produces a large amount of harmful gases during combustion, including sulfur dioxide (SO2) and nitrogen oxides (NOx). x To reduce emissions of dust and other harmful substances and meet environmental protection requirements, purification is usually required during the flue gas emission process of cement kilns.
[0003] Existing flue gas purification devices typically use activated carbon filter plates to filter and purify harmful gases in flue gas. However, activated carbon filter plates are usually connected to the device with bolts. After long-term use, activated carbon filter plates need to be cleaned or replaced. The connection with bolts makes it inconvenient to disassemble. Although the bolt connection is secure, it is cumbersome to disassemble. Disassembling bolts may require a lot of force and may even damage the equipment or the bolts themselves, increasing the difficulty of maintenance.
[0004] Therefore, we have made improvements to this and proposed a flue gas purification device based on hot raw material cement kilns. Utility Model Content

However, activated carbon filter plates are usually connected to the device by bolts. After long-term use, activated carbon filter plates need to be cleaned or replaced. Connecting the device with bolts makes disassembly inconvenient. Although bolted connections are secure, disassembly is cumbersome and may require considerable force, potentially damaging the equipment or the bolts themselves, thus increasing the difficulty of maintenance.

[0037] During implementation, flue gas enters the interior of the purification housing 1 and the connecting housing 4 through the inlet pipe 2. The water pump 604 is started. When the water pump 604 is in use, the water in the water tank 601 is transported to the interior of the outlet pipe 605 through the inlet pipe 603. The water in the outlet pipe 605 enters the interior of the diversion pipe 606.

The purified flue gas is discharged into the interior of the purification housing 1 through the outlet pipe 5. The harmful gases in the flue gas are then filtered and purified through two activated carbon filter plates 9. The completely purified flue gas is discharged through the exhaust pipe 11.
[0038] Example 2
[0039] Mounting assembly 7 includes a protective shell 701, which is fixedly mounted on the top of the rear side of the purification shell 1. A fixing bracket 702 is fixedly mounted on one side of the inner cavity of the protective shell 701. A first spring 703 is fixedly mounted in the inner cavity of the fixing bracket 702. A push plate 704 is fixedly mounted on the left side of the first spring 703. An inclined plate 705 is fixedly mounted on the top and bottom of the left side of the push plate 704. An inclined block 706 is movably connected to the left side of the inclined plate 705. A connecting plate 707 is fixedly mounted on the left side of the inclined block 706.

The inclined plate 705 then pushes the inclined block 706, which in turn moves the connecting plate 707. The connecting plate 707 then moves the locking block 708 and compresses the second spring 710, moving the locking block 708 out of the groove on the limiting plate 10. This allows the limiting plate 10 to be disassembled. The activated carbon filter plate 9 is connected to the limiting plate 10 and will be disassembled along with the limiting plate 10. When it is necessary to install the activated carbon filter plate 9, the operation is reversed, making it convenient to clean or replace the activated carbon filter plate 9.
