Integrated purification adsorption device with functions of desulfurization and denitrification

The utility model relates to an integrated purification adsorption device with functions of desulfurization and denitrification. The device is characterized by comprising an adsorbent preparation box and a reaction tower, wherein the adsorbent preparation box is used for conveying adsorbent slurry by a slurry supply pump and the upper part of a pipeline connection reaction tower; an entrance of the adsorbent preparation box is respectively connected with a water inlet pipe, an activated semi-coke powder bin, a ferric oxide powder bin and a vanadium pentoxide powder bin. The integrated purification adsorption device has the beneficial effects that 1, the device is high in desulfurization efficiency and denitrification efficiency, is capable of removing pollutants such as smoke, dust and the like, and has the advantages of being simple in flue gas treatment process and very little in water consumption, and not needing a large drainage treatment device; 2, an adsorbent is wide in source and low in price, and can be recycled; 3, the technological process is simple, easy in operation and high in adaptation ability for boiler load change; 4, the reaction tower and a regeneration tower are small in volume, so that the floor space is reduced, and separate design is realized; therefore, the integrated purification adsorption device is both suitable for reforming old power plants and building newly-built power plants.
