Abstract

The invention provides a smoke desulphurization system. The smoke desulphurization system comprises a dust removal device, a smoke inlet pipe, a smoke discharging pipe, a heat dissipating device, a desulphurization device, a heating device, an oxidization device, a demisting device, an absorption liquid storage device, a storage device and a chimney. The smoke desulphurization system is characterized in that the inlet of the heat dissipating device is connected with the outlet of the dust removal device, the outlet of the heat dissipating device is connected with one side of the lower portion of the side wall of the desulphurization device through the smoke inlet pipe, the bottom of the desulphurization device is connected with the bottom of the oxidization device, the bottom of the oxidization device is connected with the storage device, one side of the smoke discharging pipe is connected with the top of the desulphurization device, the other side of the smoke discharging pipe is connected with the demisting device, the heating device is arranged at any position between the chimney and the demisting device. The smoke desulphurization system has the advantages that the desulphurization device of the smoke desulphurization system is low in cost, the area occupied by the device is decreased, and a liquid distribution device in the system is always in a uniform spraying state in the ammonia water spraying process.

Description

technical field [0001] The invention relates to the technical field of removing sulfur dioxide in flue gas, in particular to a flue gas desulfurization 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 traditional desu...
