The flue gas treatment equipment effectively treats the toxic and harmful substances in the flue gas below the specified concentration. It should avoid dangerous phenomena such as corrosion or blockage of the equipment. Generally, flue gas treatment equipment used in waste incineration plants is divided into dust removal equipment and acid gas removal equipment. Now, as people's requirements for environmental quality increase, most waste incineration plants have added activated carbon adsorption equipment for heavy metals in the flue gas treatment process.

The flue gas treatment equipment mainly includes flue gas desulfurization tower, flue gas scrubber, absorption tower, absorption medium transmission pipe network, chimney and flue, etc., used primarily in the power industry, chemical industry, coking industry, metallurgical industry and self-provided boilers Manufacturing industry, etc.


Acid gas removal equipment

Sulphur oxide and HCl removal equipment: dry scrubber, semi-dry scrubber, wet scrubber.

Nitrogen oxide removal equipment: wet method, dry method, combustion control method.

gas scrubbers


application

Flue gas treatment equipment mainly includes flue gas desulfurization tower, flue gas scrubber, absorption tower, absorption medium transmission pipe network, chimney and flue, etc. Flue gas treatment equipment is mainly used in the power industry, chemical industry, coking industry, metallurgical industry and Manufacturing industries with self-provided boilers, etc. whose primary function is to absorb polluting, corrosive gaseous ions or molecules in the flue gas produced by fuel combustion through chemical reactions, so that the flue gas can be purified and can be directly discharged into the atmosphere without polluted environment.

There are many kinds of flue gas desulfurization processes, such as the limestone-gypsum method (WLST), seawater method (FGD), ammonia method, electron beam method, circulating desulfurization bed method, etc... There are three most commonly used desulfurization processes in China: the Limestone-gypsum method, seawater method, and ammonia method. The limestone-gypsum way is the preferred desulfurization process for most inland coal-fired power plants in China. Seawater desulfurization is mainly used in coastal areas due to its characteristics and its strong regionality. Ammonia desulfurization is used mainly in small and medium-sized boilers with a small amount of flue gas treatment. It is mainly used for flue gas purification of production-oriented enterprises' boilers.
