Technical Field

[0002] Currently, in the field of flue gas desulfurization in coal-fired power plants, over 90% of the methods used are limestone-gypsum wet flue gas desulfurization and dust removal. To modify the flow of flue gas entering the desulfurization tower, avoid flow deviation and short circuits, and achieve more uniform airflow distribution and more sufficient gas-liquid contact, structural issues such as the installation and perforation design of the turbulence tray have become crucial processes.

Furthermore, the flue gas cannot turbulently interact with the liquid, leading to uneven gas-liquid distribution, insufficient contact, and unsatisfactory mass transfer. In addition, most existing turbulence trays are fixed inside the desulfurization tower with many bolts, making the installation and disassembly process cumbersome and unfavorable for later disassembly and maintenance.
