Technical field
The utility model relates to the syndeton of a kind of spray piping and nozzle, is specifically related to a kind of quantity that can increase arrangement of nozzles, make desulfuration absorbing tower spray the arrangement of nozzles in region obtain evenly desulfuration absorbing tower slurries spray piping and the syndeton of nozzle.
Background technology
Containing sulfur dioxide in the flue gas that the industry such as coal-burning power plant produces, Sulfur dioxide pollution control technology is a lot of, such as improve energy resource structure, adopt clean fuel etc., but the irreplaceable technology of SO2 emissions is effectively cut down in flue gas desulfurization.The method of flue gas desulfurization is a lot, according to the general principle of physics and chemistry, can be divided into absorption process, absorption method and catalysis method three kinds substantially.Absorption process is most important, the most widely used method of sulfur dioxide in purifying smoke.Absorption process is divided into again dry method and wet method.
The principle of existing smoke-gas wet desulfurization utilizes the sulfur dioxide in lime stone slurry and flue gas to react, and Sulphur Dioxide is become gypsum, and reach the object removing sulfur dioxide in flue gas, its principle is as follows:
Neutralization reaction: 2CaCO
3+ H
2o+2SO
2=2CaSO
31/2H
2o+2CO
2
Oxidation reaction: 2CaSO
31/2H
2o+O2+3H
2o=2CaSO
42H
2o
