The invention provides a flue gas desulphurization system, which comprises an absorption tower and a regeneration tower, wherein the absorption tower comprises a shell, a flue gas inlet, a poor desulfurizer inlet, a clean flue gas outlet, and a rich desulfurizer outlet which is used for discharging the rich desulfurizer absorbing sulfur dioxide at the preset temperature; the regeneration tower comprises a body, a sulfur dioxide outlet, a rich desulfurizer inlet which is used for supplying the rich desulfurizer to the interior of the body, and a poor desulfurizer outlet which is located at thebottom part of the body and is used for discharging the poor desulfurizer which is parsed with sulfur dioxide after being heated, wherein the rich desulfurizer inlet of the regeneration tower is connected with the rich desulfurizer outlet of the absorption tower, and the poor desulfurizer outlet of the regeneration tower is connected with the poor desulfurizer inlet of the absorption tower. The invention can remove sulfur dioxide in the flue gas, at the same time, can produce the byproduct of sulfur dioxide with high purity, the byproduct can be used as a good raw material for producting liquid sulfur dioxide, sulfuric acid, sulfur and other chemical products, and valuable sulfur resource can be recycled.
Description
technical field [0001] The invention relates to a flue gas desulfurization system, in particular to a flue gas desulfurization system capable of regenerating a desulfurizing agent. Background technique [0002] Sulfur dioxide pollution has become an important factor restricting the sustainable development of my country's economy and society, so it is imperative to control sulfur dioxide pollution. At present, according to the different parts of the desulfurization process in production, three desulfurization methods can be used: desulfurization before combustion, desulfurization during combustion and desulfurization after combustion. Among them, flue gas desulfurization after combustion is the main means used in the world to control sulfur dioxide gas pollution. There are many kinds of desulfurization technologies, which can be roughly divided into three types: dry method, semi-dry method and wet method according to the reaction state of the desulfurization process. Among ...
