A kind of endless tube eddy flow layer and method of work thereof of desulfurizing tower
Technical field
The present invention relates to a kind of endless tube eddy flow layer and method of work thereof of desulfurizing tower.
Background technology
At present, because Wet Flue Gas Desulfurization Technique comparative maturity and adopt inexpensive absorbent becomes at present in the world the most widely used desulfur technology.Yet also exist the problem that desulfuration efficiency is not high, energy consumption level is high and desulphurization cost is high.
In wet desulfurizing process, its core is desulfurizing tower.In desulfurizing tower, sulfur-containing smoke gas is absorbed, oxidation.Wherein to be absorbed be the critical process that affects desulfuration efficiency and energy consumption to sulfur-containing smoke gas.Sulfur-containing smoke gas is easy to produce adherent phenomenon when the smoke inlet on absorption tower enters desulfurizing tower, so that partial fume is through desulfidation and do not escape.Simultaneously, flue gas is escaped and also can be produced adverse influence to the Flow Field Distribution in the desulfurizing tower, to the safe and stable operation generation negative effect of desulphurization system.
Summary of the invention
Main purpose of the present invention is to provide a kind of endless tube eddy flow layer of simple in structure, desulfurizing tower that desulfuration efficiency is high.
For addressing the above problem, the present invention adopts following technical scheme: a kind of endless tube eddy flow layer of desulfurizing tower, comprise the desulfurizing tower wall, paste the desulfurizing tower wall cloth and be equipped with annular slurries pipeline, annular slurries pipeline arranged tangential has more than one high-efficiency atomizing nozzle, and described high-efficiency atomizing nozzle is arranged on the below of annular slurries pipeline.
Further, the diameter of described annular slurries pipeline is 0.8m.
Further, described desulfurizing tower wall is cylindrical.
Another main purpose of the present invention is to provide a kind of method of work of endless tube eddy flow layer of simple in structure, desulfurizing tower that desulfuration efficiency is high.
For addressing the above problem, the present invention adopts following technical scheme: slurries paste the desulfurizing tower wall cloth and are equipped with annular slurries pipeline in endless tube eddy flow layer, and arranged tangential has high-efficiency atomizing nozzle on the pipeline, so that slurries form the field of turbulent flow under the screw; Contain the higher flue gas of sulphur concentration through the backward upper motion of smoke inlet, the ultra-fine droplet that produces with the high-efficiency atomizing nozzle effect contacts, and realizes high-efficiency desulfurization.
The endless tube eddy flow layer of desulfurizing tower of the present invention and the beneficial effect of method of work thereof are: can prevent flue gas along the escape of tower wall, so that the easier comparatively concentrated tower center of sprinkle density that flows to of flue gas; Simultaneously, reduce the diameter of desulfurizing tower, thereby simplified the tower inner structure, reduced the pipeline of arranging in the tower.The field of turbulent flow that arranged tangential has high-efficiency atomizing nozzle to produce has strengthened the uniformity that reactant mixes, and has increased the reaction specific area, has prolonged the time of reaction contact, has accelerated the speed of absorption reaction, thereby has realized high-efficiency desulfurization.

The specific embodiment
See also illustrated in figures 1 and 2, the endless tube eddy flow layer of a kind of desulfurizing tower of the present invention, comprise desulfurizing tower wall 7, paste desulfurizing tower wall 7 and be furnished with annular slurries pipeline 3, annular slurries pipeline 3 arranged tangential have more than one high-efficiency atomizing nozzle 4, and described high-efficiency atomizing nozzle 4 is arranged on the below of annular slurries pipeline 3.The field of turbulent flow that arranged tangential has high-efficiency atomizing nozzle 4 to produce has strengthened the uniformity that reactant mixes, and has increased the reaction specific area, has prolonged the time of reaction contact, has accelerated the speed of absorption reaction, thereby has realized high-efficiency desulfurization.
Wherein, the diameter of described annular slurries pipeline 3 is 0.8m, and it has the effect of similar rectification element, can prevent flue gas along the escape of tower wall, so that the easier comparatively concentrated tower center of sprinkle density that flows to of flue gas.Described desulfurizing tower wall 7 is cylindrical.
Its method of work is: slurries paste desulfurizing tower wall 7 and are furnished with annular slurries pipeline 3 in endless tube eddy flow layer, and arranged tangential has high-efficiency atomizing nozzle 4 on the pipeline, so that slurries form the field of turbulent flow under the screw; Contain the higher flue gas of sulphur concentration through the backward upper motion of smoke inlet, the ultra-fine droplet that produces with high-efficiency atomizing nozzle 4 effects contacts, and realizes high-efficiency desulfurization.
The endless tube eddy flow layer of desulfurizing tower of the present invention and the beneficial effect of method of work thereof are: can prevent flue gas along the escape of tower wall, so that the easier comparatively concentrated tower center of sprinkle density that flows to of flue gas; Simultaneously, reduce the diameter of desulfurizing tower, thereby simplified the tower inner structure, reduced the pipeline of arranging in the tower.The field of turbulent flow that arranged tangential has high-efficiency atomizing nozzle to produce has strengthened the uniformity that reactant mixes, and has increased the reaction specific area, has prolonged the time of reaction contact, has accelerated the speed of absorption reaction, thereby has realized high-efficiency desulfurization.
The above be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
