Embodiment Construction

[0045] A secondary hydraulic jacking installation method for the renovation of a flue gas desulfurization tower in a coal-fired power plant. In the renovation of the desulfurization tower in this embodiment, the original tower body is cut twice, and the height of the tower body is raised by two hydraulic jackings. remodel. It includes the following construction process steps: pre-construction preparation → dismantling the external connection of the tower → dismantling the demister → strengthening the tower body → arranging the lifting device → cutting and lifting the tower body → assembling the tower wall.

[0046] Such as Figures 1 to 2 As shown, the first lifting: lift 5.6 meters from the slurry area (6.2 meters above sea level).

[0047] 1. Construction preparation

[0048] a. Draw out the vertical and horizontal centerlines of the tower body to prepare for the positioning needs of the new tower body and other equipment;

[0049] b. According to the needs of lifting, a ...

Abstract

The invention provides a secondary hydraulic jacking installation method of smoke desulfurizing tower transformation of a coal-fired power plant, and the method is used for achieving the technical effect of conducting secondary hydraulic jacking transformation on the smoke desulfurizing tower of the coal-fired power plant. The method comprises lower tower body transformation lifting and upper tower body transformation lifting. The method comprises the following construction technological steps of pre-construction preparation, tower exterior connection detachment, demister removal, tower body reinforcement, arrangement of a lifting device, tower body cutting and lifting, and tower wall plate assembling. The installation method has the beneficial effects that the reverse installation technique of secondary hydraulic jacking is adopted for lifting and transformation of the desulfurizing tower, the welding quality is guaranteed, application of large-scale lifting equipment is reduced, and the safety of desulfurizing tower construction is improved.

Description

technical field [0001] The invention relates to the technical field of a flue gas desulfurization tower transformation method, in particular to a secondary hydraulic jacking installation method for the transformation of a flue gas desulfurization tower in a coal-fired power plant. Background technique [0002] With the rapid development of my country's economy and society, the environment has also caused serious damage, especially air pollution is worrying, so energy saving and emission reduction are very necessary. Under the background of the national ultra-low emission transformation, the original desulfurization tower ultra-low emission project of the coal-fired power plant is not up to the environmental protection standard, but the new absorption tower is limited by the space of the site, so it is of great significance to expand and upgrade the absorption tower. [0003] The hydraulic jacking installation technology of flue gas desulfurization towers in coal-fired power ...
