Summary of the invention:
The purpose of this utility model provides a kind of utilization rate and high magnesium method flue gas desulphurization spray absorber of smoke desulfurization efficiency of absorption liquid.
The technical scheme that the invention for solving the technical problem adopted is: a kind of magnesium method flue gas desulphurization spray absorber is provided, mainly by arrange from top to bottom, exhanst gas outlet, demister, demister flushing water pipeline, spraying layer, liquid re-distributor, gas distribution grid, smoke inlet, oxidation pond, tower body are formed, and feature is: oxidation pond is effluxed mouth and is formed by agitator, oxidation aeration tube, the absorption slurries outlet that circulates, additional mouthful of fresh absorption slurries, slurries; Liquid re-distributor is the ring-type hang plate that is fixed on the tower body wall, and hang plate and Ta Bichu are tightly connected, and plate is downward-sloping; Gas distribution grid is a porous plate; Two smoke inlets of tower body are symmetrically distributed in the both sides of tower body, and smoke inlet is with tangential and be tilted to following direction connection tower body; Slurries efflux mouth and are positioned at tower body awl bottom; Its feature also is: described demister is arranged between the demister flushing water pipeline; Described liquid re-distributor be arranged in spraying layer two-layer between.
The beneficial effects of the utility model are: owing to adopt two smoke inlet symmetric arrangement modes to make flue gas go into flow field symmetry behind the tower, behind the porous gas distribution grid, gas flowfield is more evenly distributed, adopt liquid re-distributor, spraying layer, demister, gas distribution grid, oxidation pond, agitator, oxidation aeration tube structure, improved the absorption liquid utilization rate and the smoke desulfurization efficiency of desulfuration absorbing tower.
