Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification equipment, in particular to a packing tower for flue gas purification and desulfurization. Background Technique

[0002] Flue gas purification is mainly achieved through a device called a packing tower. A packing tower is a device used to treat pollutants in flue gas. During the desulfurization process, the packing tower adsorbs, absorbs, or oxidizes sulfides such as sulfur dioxide in the flue gas by filling some specific packing materials, thereby reducing the sulfur content in the flue gas. As a kind of flue gas purification equipment, the packing tower is widely used in fields such as coal combustion, oil refining, and chemical industry in industrial production, and is one of the important devices for protecting the environment and reducing air pollution.

[0003] However, most traditional packing towers for flue gas purification and desulfurization adopt an integral structure, which makes it take a lot of time for users to clean and replace the packing inside the packing tower, resulting in poor convenience for maintaining and cleaning the packing tower. Moreover, traditional packing towers usually adopt a single structure and it is difficult to adjust or increase the filtration levels according to actual needs. Therefore, they are less flexible in adapting to various flue gas treatment requirements.

[0004] Therefore, those skilled in the art have provided a packing tower for flue gas purification and desulfurization to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a packing tower for flue gas purification and desulfurization is proposed.

The multi-section structure enables the packing tower to adjust the filtration levels of the packing tower according to actual needs to adapt to different flue gas treatment requirements, improves the flexibility and applicability of the equipment, and the multi-section structure design enables the packing tower to be relatively easily disassembled and maintained, facilitating cleaning and replacing the packing, thereby reducing the work difficulty and cost of users, and further enhancing the convenience of maintaining and cleaning the packing tower.
