The invention provides a wet desulphurization flue gas purification system. The wet desulphurization flue gas purification system comprises an absorption liquid storage device, a flow dividing device I, a flow dividing device II, a first-stage desulphurization device and a second-stage desulphurization, wherein both the flow dividing device I and the flow dividing device II are connected with the absorption liquid storage device; the flow dividing device I is connected with the first-stage desulphurization device ; the flow dividing device II is connected with a main desulphurization device. The innovation point is as follows: the first-stage desulphurization device comprises a spraying device I, flow guide devices, a liquid discharge device and a desulphurization device main body; the spraying device I is arranged at the top in the desulphurization device main body; the spraying device I is connected with the flow dividing device I; the flow guide devices are arranged at the top and the bottom in the desulphurization device main body ; the liquid discharge device is arranged at the bottom of the desulphurization device main body and is connected with the flow guide devices. The wet desulphurization flue gas purification system has the beneficial effects that absorption liquid sprayed by the spraying device of the desulphurization device has the same flow quantity ; the system is in a spraying state all the time and can perform desulphurization more effectively.
Description
technical field [0001] The invention relates to the technical field of removing sulfur dioxide in flue gas, in particular to a wet desulfurization flue gas purification system. Background technique [0002] At present, my country's overall emission of sulfur dioxide ranks first in the world. If the sulfur dioxide in the flue gas is directly discharged into the air, it will form acid rain and cause serious impact on the environment. Flue gas desulfurization is the removal of sulfur oxides in flue gas. Sulfur dioxide in flue gas is acidic in nature, and it can be removed from flue gas by reacting with appropriate alkaline substances. The alkalinity used reacts with the sulfur dioxide in the flue gas to produce a mixture of sulfites and sulfates (depending on the alkalinity used these salts may be calcium, sodium, magnesium or ammonium Salt). The ratio between sulfite and sulfate depends on the process conditions. In some processes, all sulfite is converted into sulfate. The...
