Abstract: The flue gas desulfurization of coal-fired power plants mostly adopts limestone-gypsum wet desulfurization technology. The absorption tower is the core equipment of the desulfurization system. As the national flue gas emission standards are raised to ultra-clean emissions, the desulfurization efficiency must be enhanced. The desulfurization absorption tower of Unit 4 of Guangzhou Yuedian Dianshan Power Plant is Japan's Chiyoda CT121 bubble tower technology. The desulfurization improvement design adds a high-position rectangular absorption tower and the bubble tower in series, and the new connecting flue is connected in series to form Double tower loop. In this construction, a 400t crawler crane was reasonably selected as the main crane, and the absorption tower and the internal device of the tower were installed in layers from bottom to top, from outside to inside.
Key words: high-level arrangement；absorption tower；straight installation method；layered installation of absorption tower and its internal equipment from bottom to top, from outside to inside；absorption tower and bubbling tower in series, double tower circulation
