S-shaped strip-shaped bubble cap desulfurization tower tray device with gradually changed height

Abstract

The invention discloses an S-shaped strip-shaped bubble cap desulfurization tower tray device with gradually changed height, which comprises at least one U-shaped support piece and a tower tray. The U-shaped support piece is fixedly arranged in an absorption tower, and the U-shaped support piece is provided with a U-shaped groove. The tower tray is vertically arranged above the U-shaped support piece, the tower tray is formed by arranging a plurality of strip-shaped plate bodies with transverse S-shaped sections in parallel, the S-shaped end parts of the adjacent plate bodies are mutually staggered and arranged at intervals, and the intervals form a middle channel. Gas sealing plates are arranged at the ends of the plate bodies and located on the two sides of a flue gas inlet. The S-shapedtops of the strip-shaped plate bodies are flush with one another. T he S-shape heights of the strip-shaped plate bodies which are sequentially arranged from the inner wall of the tower tray to the center of the tower tray are gradually increased. The tower tray device has the beneficial effects that overflowing caused by the fact that the liquid level of local slurry exceeds the upper edges of the S-shaped end parts is avoided; and gas and liquid in the tower tray are uniformly mixed, so that the overall desulfurization and dust removal efficiency of the tower tray is effectively improved, and discharge of granular heavy metals is reduced.

Description

technical field [0001] The invention relates to the technical field of desulfurization equipment, in particular to an S-shaped bubble cap desulfurization tray device with gradually changing height. Background technique [0002] At present, the flue gas desulfurization technology mostly adopts the empty tower through-flow spraying technology. On the one hand, the spray slurry directly falls into the slurry tank at the bottom of the tower, and cannot be collected and absorbed in sections. The pH value of the slurry has no gradient. When the reaction tends to the equilibrium point, the desulfurization efficiency It is difficult to improve; on the other hand, the dust removal efficiency of spray washing is very low for the fine dust in the flue gas, especially the fine dust of PM2. The droplets are carried away, and the gypsum contained in these fine droplets also increases the dust emission concentration. [0003] As an important source of heavy metal emissions, coal-fired pow...
