Abstract

The invention discloses an SCR denitration device for pellet production tail gas, and relates to the field of pellet production tail gas purification. The SCR denitration device includes a dust removal device, a temperature raising device, an SCR denitration device body, a dewhitening heat exchange device and a desulfurization device, and the tail gas flows along a main exhaust air duct, and passes through the dust removal device, the temperature raising device, the SCR denitration device body, the dewhitening heat exchange device and the desulfurization device; and after desulfurization treatment, part of the tail gas is returned to the dewhitening heat exchange device, being subjected to heat exchange with the tail gas in the main exhaust air duct, and then mixed with the tail gas afterdesulfurization treatment and discharged. The invention further discloses a denitration treatment method. According to the SCR denitration device for the pellet production tail gas, the catalytic efficiency of SCR denitration is improved, and denitration products are free of secondary pollutants; by recycling excess heat, the desulfurization efficiency is improved and tail gas dewhitening is facilitated, the energy efficiency is effectively improved, and the operating cost is lowered.

Description

technical field [0001] The invention relates to the field of pellet production tail gas purification devices, in particular to an SCR denitrification device for pellet production tail gas. Background technique [0002] At present, for the denitrification treatment of pellet production tail gas, some manufacturers adopt the oxidation denitrification process, which consumes a lot of energy, high operating costs, low efficiency, and the denitrification rate is only about 80%, and its products such as nitric acid and nitrate Solid waste such as nitric acid is likely to cause secondary pollution to the environment and cannot meet the increasing environmental protection requirements. [0003] Therefore, those skilled in the art are devoting themselves to developing a denitrification treatment device that not only saves energy, reduces operating costs, but also can effectively improve denitrification efficiency, and the denitrification products are environmentally friendly and have...
