Abstract

The invention provides a thermal regeneration method of activated carbon. The method comprises the steps of (1) transferring activated carbon which adsorbs pollutants including sulfur oxide, nitrogen oxide and dioxin in an adsorption tower of a dry process desulphurization and denitration device into an activated carbon analysis tower from the bottom of the adsorption tower, wherein the desulphurization and denitration device comprises the activated carbon adsorption tower and the activated carbon analysis tower; and (2) carrying out heat exchange on the activated carbon and heating gas in the analysis tower to enable the activated carbon to be heated up to the activated carbon regeneration temperature T1 to enable the activated carbon to be analyzed and regenerated at the temperature T1, wherein the heating gas is high temperature flue gas G1 coming from one or two bellows at the tail of a sintering machine, or hot air G2 formed by indirect heat exchange between air with room temperature and the high temperature flue gas G1 coming from the one or two bellows at the tail of the sintering machine. The invention also provides a regeneration device of activated carbon.

Description

technical field [0001] The present invention relates to the thermal regeneration method of active carbon and its device in the dry desulfurization that comprises active carbon adsorption tower and desorption tower, denitrification device and technology, more specifically, relate to utilizing the high-temperature flue gas of sintering machine to come from flue gas or waste gas ( Especially the activated carbon adsorption desulfurization (SO 2 ), denitrification (NO x ) The method for thermally regenerating activated carbon in the process belongs to the field of environmental protection and energy saving, that is, the field of sintering flue gas treatment. Background technique [0002] For industrial flue gas, especially sintering machine flue gas in the iron and steel industry, it is ideal to use desulfurization and denitrification devices and processes including activated carbon adsorption towers and desorption towers (or regeneration towers). Activated carbon desulfurizat...
