Abstract

A reduction in gas-liquid contact efficiency is suppressed by a simple structure. Filler (11B) is installed in the inside of the packed tower, and is poured with water from the vertical direction upward so that the water circulates inside and the exhaust gas circulates inside, so that the exhaust gas is desulfurized by contacting the water. filler. The filler (11B) has: a first plate unit (64) having a plurality of plate portions (62A) extending in the vertical direction and provided at predetermined intervals; and a second plate unit having the same The plate parts (62) of the plate unit (64) intersect and extend along the vertical direction, and a plurality of plate parts (72) arranged at regular intervals, and the second plate unit and the first plate unit (64) together A lattice portion (69) having openings at both ends along the vertical direction is formed. The thickness of the plate portion (62) decreases from the upper end surface (66) in the vertical direction toward the lower end surface (67).

Description

technical field

[0001] The invention relates to a packing material for a packing tower and a seawater desulfurization device. Background technique

[0002] In recent years, thermal power plants equipped with seawater desalination equipment have tended to increase. In addition, a desulfurization device is installed to remove sulfur components contained in exhaust gas generated by burning fossil fuels such as coal. Seawater desulfurization, which utilizes seawater as an absorbing liquid to desulfurize, is attracting attention from the viewpoints of building near the sea because a large amount of cooling water is required in power stations, etc. . This seawater desulfurization device using seawater as an absorbent is used in thermal power plants and the like because it is less expensive than the lime-gypsum method.

[0003] This seawater desulfurization device includes, for example, Patent Document 1, which includes an exhaust gas desulfurization absorption tower (packed tow...
