Abstract
The invention discloses a cyclone plate tower desulfurizing unit and a working method thereof. The desulfurizing unit comprises a cyclone plate tower and a dehydrating tower, wherein the lower part of the cyclone plate tower is provided with a Venturi throat, and the Venturi throat is connected with a fume inlet and a lime water outlet pipe; the lime water outlet pipe is connected with a three-stage precipitation tank; the upper part of the cyclone plate tower is provided with a lime water inlet pipe; and the lime water inlet pipe is connected with a lime slaking tank. The invention has the main characteristics of large gas-liquid contact area, simple structure, low resistance force, stable operation and high desulfurization and dust removal efficiency.
Description
Technical field
The present invention relates to a kind of rotating stream tray scrubber desulfurizer and method of work thereof.
Background technology
Since early 1980s, along with China's economy continues to develop rapidly, the coal Year's consumption is with 5～12% speed cumulative year after year, and the annual emissions of SO2 is increasing year by year also.To 20 end of the centurys, the annual emissions of China SO2 is up to more than 2,000 ten thousand t, and China becomes the in the world the most serious country of air environmental pollution, also becomes in the world the third-largest Acid Rain Zone under the contamination of SO2.In 113 national prevention and control of air pollution key cities in 2002, have 40 average daily concentration of city SO2 to surpass national grade ii standard, account for 35.4%, the city that particle exceeds standard accounts for 72.6%.30 urban air-qualities are up to standard, and 44 urban air-qualities are three grades, and 39 urban air-qualities are inferior to three grades.Because coal fire discharged SO2 belongs to without the control discharging, China's Acid Rain Pollution also is difficult to control, and China's Acid Rain Pollution area accounts for more than 1/3rd of territory total area basically.China's atmosphere pollution is so serious, becomes in the world today to the greatest extent without only country.Future, economic rapidly sustainable development, the discharge capacity of SO2 also can increase year by year, and air environmental pollution control allows of no optimist.
Summary of the invention
Main purpose of the present invention is to provide a kind of desulfuration efficiency high, the rotating stream tray scrubber desulfurizer of applied range.
For addressing the above problem, the present invention adopts following technical scheme: a kind of rotating stream tray scrubber desulfurizer, comprise interconnective rotating stream tray scrubber and dehydrating tower, the bottom of rotating stream tray scrubber is provided with Venturi throat, Venturi throat is connected with gas approach, Venturi throat also connects limewash and goes out pipe, and limewash goes out pipe and connects three grades of sedimentation basins; The top of rotating stream tray scrubber is provided with the limewash inlet pipe, and the limewash inlet pipe connects lime slaker.
Further, described three grades of sedimentation basins and lime slaker interconnect.
Further, described dehydrating tower is provided with exhanst gas outlet.
Another main purpose of the present invention is to provide a kind of desulfuration efficiency high, the method for work of the rotating stream tray scrubber desulfurizer of applied range.
For addressing the above problem, the present invention adopts following technical scheme: sulfur-containing smoke gas is decreasing temperature and increasing humidity behind Venturi throat, and the gas approach bottom rotating stream tray scrubber advances in the tower with tangential direction, with movable on the speed screw of 2m/s; Under the effect of centrifugal force, in the flue gas the above flue dust of 10 μ m and chemical absorbing the limewash drop of SO2 got rid of inwall to tower, the wetted rear mass penalty of flue dust, under action of gravitation, wetted flue dust, moisture film ring and limewash drop are movable at the bottom of together along inner wall of tower to tower, through three grades of sedimentation basins lime-ash are separated; Isolated water purification is in being pumped into lime slaker, and the flue gas after desulfurization and the udst separation contains a large amount of water smoke, is discharged in the atmosphere through exhanst gas outlet after the dehydrating tower dehydration again.
The beneficial effect of rotating stream tray scrubber desulfurizer of the present invention and method of work thereof is: its gas-liquid contact area is large, simple in structure, resistance is less, stable, desulfurization and efficiency of dust collection are high is main feature.
Description of drawings
Fig. 1 is the front view of rotating stream tray scrubber desulfurizer of the present invention.
The specific embodiment
See also shown in Figure 1, a kind of rotating stream tray scrubber desulfurizer of the present invention, comprise interconnective rotating stream tray scrubber 1 and dehydrating tower 2, the bottom of rotating stream tray scrubber 1 is provided with Venturi throat 3, Venturi throat 3 is connected with gas approach 4, Venturi throat 3 also connects limewash and goes out pipe 5, and limewash goes out pipe 5 and connects three grades of sedimentation basins 6; The top of rotating stream tray scrubber 1 is provided with limewash inlet pipe 7, and limewash inlet pipe 7 connects lime slaker 8.
Wherein, described three grades of sedimentation basins 6 and lime slaker 8 interconnect.Described dehydrating tower 2 is provided with exhanst gas outlet 9.
Sulfur-containing smoke gas is decreasing temperature and increasing humidity behind Venturi throat 3, advances in the tower with tangential direction from the gas approach 4 of rotating stream tray scrubber 1 bottom, with movable on the speed screw of 2m/s.Under the effect of centrifugal force, in the flue gas the above flue dust of 10 μ m and chemical absorbing the limewash drop of SO2 got rid of inwall to tower, the wetted rear mass penalty of flue dust, under action of gravitation, wetted flue dust, moisture film ring and limewash drop are movable at the bottom of together along inner wall of tower to tower, through three grades of sedimentation basins lime-ash are separated.Isolated water purification is in being pumped into lime slaker 8.Flue gas after desulfurization and the udst separation contains a large amount of water smoke, is discharged in the atmosphere through exhanst gas outlet 9 after dehydrating tower 2 dehydrations again.
The beneficial effect of rotating stream tray scrubber desulfurizer of the present invention is: its gas-liquid contact area is large, simple in structure, resistance is less, stable, desulfurization and efficiency of dust collection are high is main feature.
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.
