Description

Technical Field

[0001] This utility model relates to the field of desulfurization absorption tower technology, and in particular to an ammonia-based desulfurization absorption tower. Background Technology

[0002] Ammonia-based desulfurization absorption towers are highly efficient desulfurization devices that use ammonia water as the absorbent to absorb sulfur dioxide in flue gas, thereby achieving desulfurization. Ammonia-based desulfurization absorption towers typically consist of a tower body, packing layer, distribution system, collection device, exhaust system, circulating pump and pipelines, and control system. They are usually equipped with filter plates to filter the flue gas.

[0003] An existing patent, CN216653807U, describes a chloride ion absorption tower for ammonia desulfurization, relating to the field of ammonia desulfurization technology. The tower includes a tower body with an installation opening on one side of its outer wall. An installation door, covering the installation opening, is hinged to one end of the bottom inner wall of the installation opening. Sliding grooves are formed on both sides of the inner wall of the installation opening. A common dust removal screen plate is slidably connected between the inner walls of the two sliding grooves. A common rotating shaft is connected between the two sides of the tower body via bearings. The rotating shaft is located above the dust removal screen plate. An adjusting plate is fixedly connected to the side of the rotating shaft near the installation door. L-shaped adjusting rods are fixedly connected to both sides of the bottom of the adjusting plate. The portion of the adjusting rod parallel to the sliding groove is located within the sliding groove. Fixing grooves are formed on both sides of the top of the dust removal screen plate. The end of the adjusting rod near the fixing groove contacts the bottom inner wall of the fixing groove. This invention facilitates easy replacement and cleaning of the dust removal screen plate by workers.

[0004] Regarding the aforementioned technologies, the existing absorption towers have the following drawbacks: after prolonged use, the filter plates installed inside the absorption tower will be clogged by particles in the flue gas. However, the filter plates are usually fixed with bolts, requiring the old filter plates to be removed and new filter plates to be installed, which is cumbersome. Therefore, this utility model provides an ammonia desulfurization absorption tower. Utility Model Content
