Abstract
The utility model discloses a spiral-flow type desulfurizing absorption tower. A slurry pond (2) containing a washing liquid is arranged at the bottom part of an absorption tower (1); a stirring device (3) is mounted in the slurry pond (2); a fume inlet flue (4) is connected to an opening on the lateral wall at the middle part of the absorption tower (1); a fume outlet flue (5) is connected to an opening at the top part of the absorption tower (1); and a spray layer (6) and a demister (7) are arranged in the absorption tower (1) between the fume inlet flue (4) and the fume outlet flue (5) in sequence. The swirl type desulfurizing absorption tower is characterized in that the cross section of the absorption tower (1) is circular; the outlet end of the fume inlet flue (4) is tangent to the absorption tower (1); and fume tangentially enters the absorption tower (1) and forms a spiral flow. The fume tangentially enters the absorption tower and forms the spiral flow, so that a fume flowing dead area is eliminated and the distribution of the fume is more uniform. Meanwhile, the dwell time of the fume in the chemical reaction area of the desulfurizing tower is also prolonged; and the slurry contact from top to bottom is full and has longer time, thereby achieving the effect of improving the desulfurizing efficiency of SO2.
Description
Technical field
The utility model belongs to a kind of flue gas desulfur device, specifically, is a kind of flue gas forms eddy flow in the absorption tower desulfuration absorbing tower.
Background technology
Flue gas desulfurization technique comprises wet desulphurization and dry desulfurization etc.The utilization of wherein wet desulphurization technology is the most extensive.Wet process of FGD is the technological process that current 85% left and right sides large thermal power plant in the world adopts, and fume desulfurating absorption tower is its key core equipment, has obtained extensive use on engineering.The principle of wet flue gas desulfurization absorption tower is to utilize the lime stone alkaline slurry to spray from the top down, and flue gas flows from bottom to top, and lime stone slurry drops in the SO that absorbs in the dropping process in the flue gas
2, reach the SO that removes in the flue gas
2Purpose.
At present, shortcomings such as existing because wet process of FGD technology has all that investment is big, power consumption is big, floor space is big, equipment is complicated, operating cost and specification requirement height, now Yun Hang wet flue gas desulfurization absorption tower generally adopts single inlet turriform, the inner flow of flue gas of its desulfuration absorbing tower is very inhomogeneous, even can form the territory, dead area, its flow behavior directly influences the desulfuration efficiency of desulfuration absorbing tower.The operational efficiency that how to improve wet desulphurization absorption tower has become the problem that presses for solution in desulfuration absorbing tower field with the operation energy consumption that reduces desulfuration absorbing tower.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of flue gas to form eddy flow in the absorption tower, and uniform spiral-flow type desulfuration absorbing tower flows.
The technical solution of the utility model is as follows: a kind of spiral-flow type desulfuration absorbing tower, and agitating device is equipped with in the slurries pond of bottom, absorption tower for cleaning solution is housed in this slurries pond; Described absorption tower medial side wall opening is connected with flue; The open top of described absorption tower connects smoke outlet flue, spraying layer that is provided with in the absorption tower between described flue and smoke outlet flue and demister, its key is: described flue port of export center line is with tangent less than the circle of absorption tower inwall, and flue gas tangentially enters the absorption tower and forms eddy flow.
Flue gas tangentially enters the absorption tower and forms eddy flow.The lime stone slurry of doing cleaning solution from top to bottom, flue gas is haptoreaction from bottom to top.The flue gas that forms eddy flow can be eliminated the territory, dead area of flowing in the desulfuration absorbing tower, guarantees that flow field in tower is more even.
Above-mentioned absorption tower is connected with two flues, and described two flues lay respectively at the absorption tower opposite side, and described two flues output flue gas direction is opposite.Opposite side enters simultaneously, and flue gas is more even, and can form the acceleration formation eddy flow of making a concerted effort.
Above-mentioned two flue entrance points connect same main flue, in described two flues control baffle plate are housed all.Can make that two flue flue gas flows are suitable by the control baffle controls.
Beneficial effect: the utility model makes flue gas tangentially enter the formation eddy flow, has eliminated the flow of flue gas dead area, makes smoke distribution more even.Also prolonged the time of staying of flue gas in desulfurizing tower chemical reaction zone simultaneously, contacted more fully with top-down slurries, the time is longer.Reach and improve SO
2The effect of removal efficiency.
