Abstract
The present invention relates to a sloping plate device at the inlet section of a flue gas desulfurizing absorption tower, which comprises a flue gas passage which is communicated with a tower body and is composed of an outer flue gas section and an inner flue gas section, wherein the outer flue gas section is formed by surrounding an outer top plate, an outer side plate and an outer bottom plate; the inner flue gas section is formed by surrounding an inner top plate, an inner side plate and inner bottom plate; the outer flue gas section and the inner flue gas section are tilted downwards from inward to outward and are butted with the opening rim of the tower wall of the absorption tower respectively; the outer surface of the butt end of the outer top plate, the outer side plate and the outer bottom plate is in an oblique section and extends outside the part of 1/2 of wall thickness of the absorption tower to be welded; the butt end of the inner top plate, the inner side plate and the inner bottom plate extends to the part of 1/2 of the wall thickness in the absorption tower to be welded; the seaming parts of the outer flue gas section and the inner flue gas section are welded, and the sloping plate is welded between the end of the inner top plate and the inner wall of the absorption tower above the inner top plate. The present invention has the advantages that the corrosion of the flue gas passage is reduced because limestone slurry sprayed from top to bottom through a spraying layer is prevented from entering the flue gas passage at the inlet of the absorption tower, the flue gas distribution at the inlet section is improved effectively, the obstruction of the flow field in the tower does not exist, and the desulfurization efficiency of the absorption tower is improved.
Description
(1), technical field
The present invention relates to the syndeton of a kind of fume desulfurating absorption tower and flue.
(2), background technology
Power station and industrial boiler adopt coal and wet goods fossil fuel usually, because these fossil fuels generally contain the composition of sulphur, therefore, can produce harmful substances such as sulfur dioxide in combustion process.In order to remove the sulfur dioxide in the boiler smoke, be extensive use of lime stone one gypsum wet flue gas desulfurizing device in the large-sized station boiler.Because the design of the desulfurizer of Power Plant in China is that benchmark designs with the sulfur content of design coal basically, and the most power plant of China all exist coal-fired source instability, coal-fired quality instability and unit load variation problem greatly, simultaneously, be accompanied by China the coal-fired sulfur content in city is carried out more and more stricter restriction, make traditional lime stone one gypsum wet flue gas desulfurizing device face transformation.The syndeton of existing fume desulfurating absorption tower and flue, because the porch is dried wet interface, the environment very severe, the lime stone slurry that sprays from top to bottom by spraying layer is easy to pour in down a chimney in the flue of porch, absorption tower, and this place's flue is corroded very soon.On the other hand, the skewness of flue entrance section flue gas had both influenced the desulfuration efficiency on absorption tower, had also increased operation energy consumption.
(3), summary of the invention
The purpose of this invention is to provide a kind of sloping plate unit in entrance of flue gas-desulfurizing absorption tower, solve lime stone slurry and be easy to pour in down a chimney in the flue of porch, absorption tower, make this place's flue problem of corrosion easily; And solution improves flue gas flow field skewness in the absorption tower, needs the further technical problem that improves traditional absorption tower desulfuration efficiency, further cuts down the consumption of energy.
Technical scheme of the present invention: this sloping plate unit in entrance of flue gas-desulfurizing absorption tower, comprise the flue that is communicated with tower body, it is characterized in that: flue is made up of outer section of flue and flue inner segment, surround by roof sheet, outer panel and Outer Bottom Plating and to form the outer section of flue, surround by inside ceiling panel, interior plate and inner bottom plating and form the flue inner segment; Outer section of its flue and flue inner segment, dock with absorbing Tata wall perforate edge respectively to interior downward-sloping from outer, and the butt end of roof sheet and Outer Bottom Plating extends the outer 1/2 place welding of absorption tower wall thickness; The butt end of inside ceiling panel and inner bottom plating extends 1/2 place welding in the wall thickness of absorption tower; Outer section seam crossing with the flue inner segment of flue welds; Weld swash plate between the absorption tower inwall of inside ceiling panel end and its top.
Outside, the butt end of above-mentioned roof sheet, outer panel and Outer Bottom Plating is oblique profile, with the flue inner segment with to absorb the Tata wall be the groove welding.
The angle of inclination of above-mentioned swash plate is 40 °-50 °.
Above-mentioned swash plate is a carbon steel sheet, and outer surface sprays glass flake or serves as a contrast anticorrosion glue-line.
Ribbed stiffener is established in the bight that folds between the bight that folds between above-mentioned swash plate and inside ceiling panel end and the absorption tower inwall, swash plate and the absorption tower inwall.
The length that above-mentioned flue inner segment tiltedly stretches in the absorption tower is 0.6 meter to 1.2 meters.
The length that above-mentioned flue inner segment tiltedly stretches in the absorption tower is that inside ceiling panel is longer, and inner bottom plating is shorter.
Outer section of above-mentioned flue and flue inner segment are the 5-15 degree from outer extremely interior downward-sloping angle.
The present invention has two main advantages, at first, has built under the situation about finishing on the absorption tower, can stop the lime stone slurry that sprays by spraying layer to enter porch, absorption tower flue effectively from top to bottom, reduces the corrosion to this place's flue.Secondly, from the eminence spray and lime stone slurry down forms cascade at this entrance swash plate place, can improve the distribution of entrance flue gas effectively, promote the unobstructed of flue gas flow field distribution in the tower, help improving the desulfuration efficiency on absorption tower.The present invention also has easy construction, working face is little, and the advantage that cost is low is widely used in the transformation on newly-built absorption tower and existing absorption tower.
