[0002] Compared with the traditional wet flue gas desulfurization, activated carbon desulfurization and denitrification technology is a new type of dry flue gas desulfurization technology, which usually uses activated carbon as an adsorbent and combines it with the addition of NH3 for denitrification. Traditional wet desulfurization technology has problems such as consuming a large amount of water resources, difficult wastewater treatment and high costs. Therefore, dry desulfurization technology has gradually attracted attention.
[0003] Activated carbon desulfurization and denitrification activated carbon will be transported to the adsorption tower and regeneration tower by a Z-type chain bucket conveyor. The activated carbon in the regeneration tower is subjected to high-temperature analysis and unloaded to the vibrating screen through a long roller unloader and a double-valve core unloading valve. The vibrating screen vibrates back and forth to screen out the smaller activated carbon particles, and the larger activated carbon particles are transported to the adsorption tower by a chain bucket conveyor for reuse.
