Problems solved by technology

However, since the original flue gas volume and the concentration of pollutants in the flue gas are different for each project, and the flue gas volume and the difficulty of pollutants often fluctuate, it is not scientific to set the activated carbon circulation volume of the system according to the maximum demand. , resulting in a great waste of

Abstract

The invention discloses a flue gas desulfurization and denitrification activated carbon distribution system. The system comprises an analysis tower, a desulfurization tower and a denitrification tower. The raw flue gas sequentially passes through the desulfurization tower and the denitration tower to be subjected to desulfurization and denitration treatment. A discharge port of the desorption tower is connected with a feed port of the denitration tower through a first activated carbon conveying device. A discharge port of the desulfurization tower is connected with a feed port of the desorption tower through a second activated carbon conveying device. The discharge port of the denitration tower is connected with a feed port of the desulfurization tower through a third activated carbon conveying device. A first bypass activated carbon conveying device is led out from the first activated carbon conveying device and is communicated with the third activated carbon conveying device or the feeding port of the desulfurizing tower. According to the invention, independent and accurate control of the activated carbon circulation amount of the desulfurization tower and the denitration tower is realized, the loss of activated carbon is reduced, and the operation cost and the dust emission concentration are reduced.

Description

technical field [0001] The invention relates to flue gas treatment equipment technology, in particular to a flue gas desulfurization and denitrification activated carbon distributing system and a distributing method, belonging to the technical field of flue gas purification. Background technique [0002] In iron and steel plants, many flue gas purification adopts two-stage activated carbon flue gas purification process: the flue gas process is that the flue gas passes through the first-level adsorption tower (the main function is desulfurization) and the second-level adsorption tower (the main function is denitrification), and then flows from the chimney Discharge; the process of activated carbon is: the activated carbon after analysis is transported to the secondary adsorption tower by the feeding conveyor of the secondary tower, and after the activated carbon absorbs some pollutants, it is sent to the primary adsorption tower by the conveyor of the primary tower to absorb t...
