Integrated industrial waste gas treatment for desulfurization and denitrification. Large particle activated carbon (also known as "active coke") is a type of coal-based granular activated carbon, which is sintering exhaust gas (sintering machine exhaust gas) of iron and steel plants, exhaust gas of thermal power plants, exhaust gas of coking plants and various smelting exhaust gases The special processing products can not only simultaneously purify SO2 and NOX, but also reduce dust pollution.

Different from conventional activated carbon, desulfurization and denitration activated carbon is an adsorbent with high comprehensive strength (pressure resistance, wear resistance), small specific surface area, and large sulfur capacity. In the process of use, heating regeneration is equivalent to reactivating activated carbon. , Its desulfurization and denitration performance will be increased. The removal rate of SO2 by this product can reach more than 98%, the removal rate of nitrogen oxide can reach more than 85%, and it can also absorb dust content in the range of about 20 mg per cubic meter.

The desulfurization and denitrification activated carbon produced by Huahui Company has cylindrical bodies with diameters of Ø5mm and Ø9mm respectively. It is an adsorbent with a developed comprehensive strength (extrusion resistance, abrasion resistance, and impact resistance) with a developed ratio of mesopores and a high sulfur capacity. , Higher strength and higher ignition point, have very good removal ability for SO2, SO3 and NOx.
