Absorption tower of multi-furnace one-tower desulfurizer

Abstract

The invention relates to an absorption tower of a multi-furnace one-tower desulfurizer. The absorption tower comprises an absorption tower shell, and a slurry tank area, an inlet flue, a spraying layer and a demister which are arranged in the absorption tower shell from bottom to top, wherein at least one clapboard is arranged in the absorption tower shell and penetrates through the internal area of the absorption tower shell in which the inlet flue, the spraying layer and the demister are positioned to divide the absorption tower at the section into at least two independent sub-areas, and all independent sub-areas are provided with independent sub-inlet flues, sub-spraying layers and sub-demisters. Each area of the absorption tower can operate independently, so that when flue gas volume changes more violently, each area can be ensured to work in the best flue gas velocity range, and other areas can be shut down so as to ensure efficient economical operation under various working conditions. Therefore, the absorption tower can give consideration to full-load and low-load operation economical efficiency, thereby having obvious energy-saving benefit.

Description

Technical field [0001] The invention relates to the technical field of flue gas desulfurization technology and equipment in the field of environmental protection, and particularly relates to an absorption tower of a multi-furnace one-tower desulfurization device, which can be used in electric power, cement, metallurgy, chemical and other industries. Background technique [0002] Existing desulfurization devices mostly adopt the configuration of one furnace and one tower (tower without clapboard). This configuration is only suitable for flue gas desulfurization of large-scale units. For users with multiple furnaces in small and medium-sized units, if the configuration of one furnace and one tower is still adopted, The system is more complicated, occupies a large area, and high cost. [0003] However, if the existing tower type without clapboard is used, if it is configured with multiple furnaces and one tower (tower without clapboard), when a single furnace is operated under low loa...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing desulfurization devices adopt the configuration of one furnace and one tower (tower without partition), which is only suitable for the flue gas desulfurization of large-scale units. The system is more complicated, occupies a large area, and is expensive.

[0003] However, if the existing non-partition tower type is used, if it is configured according to the multi-furnace one tower (no-partition tower type), when a single furnace operates under low load conditions, the flue gas flow rate in the absorption tower is too low, which deviates far from the design. High-efficiency zone, which leads to low absorption efficiency of the absorption tower and high energy consumption in low-load operation
