Abstract
The utility model discloses a novel unevenly porous air distribution plate, which comprises a round plate body. The round plate body is divided into eight areas along the vertical direction, each area is provided with round openings, the openings in the same area have the same porosity, and the porosity of the openings in different areas gradually decreases along the airflow direction. The air distribution in a desulfurization tower can be significantly made more uniform. Moreover, when the novel unevenly porous air distribution plate is used, no obvious vortex can be formed in the desulfurization area on the plate, the desulfurization efficiency can be increased significantly, and environmental pollution can be reduced.
Description
Technical field
The utility model relates to a kind of even distributing wind device that is used in the desulfurizing tower, is specifically related to a kind of novel non-homogeneous perforate air distribution plate.
Background technology
At present, in the desulfurizing tower flue gas is carried out desulfurization removing nitric and enjoy social concerns.Yet because the air-flow distribution is very inhomogeneous in the desulfurizing tower, local air flow is too fast, and flue gas holdup time in desulfurizing tower is very short, causes desulphurization reaction incomplete, has a strong impact on desulfurized effect.In the prior art, the holdup time of prolong smoke in tower that two sets of plan can be arranged: the one, the height of increase tower, this obviously can increase initial cost; The 2nd, cut down the flow velocity of flue gas in tower, though this scheme can increase the flow of flue gas resistance, thus the power of increase blower fan, this is relative realistic plan.Find that with air-flow distribution in the fluent software simulation desulfurizing tower after gas got into desulfurizing tower, obviously tower wall (away from the tower wall of air inlet) flow through along the left side,, produce local decompression and make the interior right side of tower form a big eddy current because left side this strand air-flow velocity is too fast.So the Flow Field Distribution rule that produces is: the left side ascending air is very fast in the tower, and the right side air-flow sinks to producing eddy current.The left side air velocity reaches 10m/s, and flue gas time of staying in a 14m high tower has only 1.4s, needs the time (being generally 2s) less than sweetening process, causes left side flue gas desulfurization incomplete.The down draft that the right side produces also can influence the effect of spray.In addition, because the left side air-flow is too fast, the byproduct (bisulfite ammonia etc.) that the ammonia process of desulfurization is produced flies away with flue gas, does not also pollute the environment if do not add these byproducts of processing.
Avoiding the interior air-flow rising of tower effective ways too fast and the interior formation of tower eddy current is that air distribution plate is installed in desulfurizing tower; Yet traditional even perforate air distribution plate; It like percent opening 50% even perforate air distribution plate; Effect is not clearly, and Ta Neibu wind is still even inadequately in the use, and has tangible eddy current.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of novel non-homogeneous perforate air distribution plate.
Its technical solution is:
A kind of novel non-homogeneous perforate air distribution plate comprises circular plate body, and said circular plate body longitudinally is divided into 8 zones, round hole all is set in each zone, and the same area open interior rate is identical, and interregional percent opening reduces along airflow direction successively.
Be made as 70%, 65%, 60%, 50%, 40%, 35%, 30%, 25% successively along above-mentioned each the regional opening rate of airflow direction, be made as 1080mm, 440mm, 460mm, 250mm, 420mm, 750mm, 650mm, 350mm successively along above-mentioned each peak width of airflow direction.
The aperture of above-mentioned round hole is 50mm, is made as 106mm, 110mm, 114mm, 125mm, 140mm, 150mm, 162mm, 177mm successively along the spacing between the adjacent apertures in each zone of airflow direction.
The useful technique effect of the utility model is:
The utility model can significantly make air-flow more even distribution in the desulfurizing tower, and in use, the desulfurization zone, top of the utility model does not have tangible eddy current, has significantly improved desulfuration efficiency, has reduced environmental pollution.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is installed in the structural representation in the desulfurizing tower for the utility model.
The specific embodiment
In conjunction with Fig. 1, a kind of novel non-homogeneous perforate air distribution plate comprises circular plate body 1, and the diameter of circular plate body 1 is 4.4m, and longitudinally dotted line is divided into 8 zones, and the same area open interior rate is identical, and interregional percent opening reduces along airflow direction successively.Round hole 101 all is set in each zone; The radius of round hole 101 is 50mm; Be made as 70%, 65%, 60%, 50%, 40%, 35%, 30%, 25% successively along each regional opening rate of airflow direction; Be made as 1080mm, 440mm, 460mm, 250mm, 420mm, 750mm, 650mm, 350mm successively along each peak width of airflow direction, be made as 106mm, 110mm, 114mm, 125mm, 140mm, 150mm, 162mm, 177mm successively along the spacing between the adjacent apertures in each zone of airflow direction.
Fig. 2 is installed in the structural representation in the desulfurizing tower for the utility model; The height of desulfurizing tower is 14m; Diameter is 4.4m, is provided with flue gas inlet port 2 on the right side, bottom of desulfurization Tata wall, is provided with flue gas discharge opening 3 in the upper left-hand of desulfurization Tata wall; Above-mentioned flow direction when airflow direction is meant that air-flow gets into beginning in the desulfurizing tower promptly flows from right to left.When air flow stream is crossed circular plate body 1; Because the percent opening in circular plate body 1 left side is less than the percent opening on right side; Then can make the air-flow deceleration faster of tower wall left side flow velocity on the one hand; Flow velocity slower air-flow in Ta Bi right side is quickened, reach the effect that circular plate body 1 top desulfurization regional gas stream is evenly distributed.
Need to prove that under the instruction of this specification, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection domains of the utility model.
