摘要

针对托盘参数对脱硫塔脱硫效率及能耗的影响展开研究，通过搭建的大型热态试验平台，研究托盘不同孔径、开孔率、开孔形式、堰板高度及不同的安装位置对脱硫效率和能耗的影响，首次提出能耗效率比作为评价脱硫塔运行经济性的指标。结果表明：在液气比较小（不大于13.6 L/m~3）时，选择中等孔径、较高堰板、较小开孔率、低位布置、新形开孔的托盘脱硫塔运行经济性较好；在液气比较大（大于13.6 L/m~3）时，选择中等孔径、较高堰板、较大开孔率、高位布置、新形开孔的托盘脱硫塔运行经济性较好。该结论对脱硫塔托盘设计选型具有指导意义。

Abstract

The effects of tray parameters on desulfurization efficiency and energy consumption of desulfurization towers are investigated. Through the large-scale hot test platform

the effects of different pore diameters

opening ratio

opening form

weir plate height and different installation positions on desulphurization efficiency and energy consumption are studied. In this paper

the energy consumption efficiency ratio is proposed for the first time as an index to evaluate the operation economy of desulfurization tower. It is found that

under the conditions of experimental platform

when the liquid-gas ratio is not more than 13.6 L/m~3

it is economically advantageous to choose sieve plate with medium aperture

high weir board

small opening rate

low-level arrangement

and new aperture design. When the liquid-gas ratio is large than 13.6 L/m~3

it is economically advantageous to choose sieve plate with medium aperture

high weir board

large opening rate

high-level arrangement

and new aperture design.The conclusion is of guiding significance for the design and selection of sieve plates for desulfurization and desulfurization towers.
