Problems solved by technology

[0007] Aiming at the problems in the prior art that fouling is prone to occur in the activated carbon desorption tower and activated carbon "bridges" cause spontaneous combustion of activated carbon, the purpose of the present invention is to make the temperature at the upper end of the cooling section of the adsorption tower close to the temperature of the heating zone, and there is a buffer zone. Prevent activated carbon from fouling on the upper tube plate of the cooling section of the adsorption tower, resulting in clogging and corrosion of the desorption tower; at the same time, set a "buffer zone" to avoid spontaneous combustion of activated carbon caused by "bridge"

Abstract

The invention provides a novel activated carbon desorption tower, the activated carbon desorption tower includes a heating section, a first transition section, a transition cooling section, a second transition section and a heat exchange cooling section arranged from top to bottom; the transition cooling section, the second transition section Sections together constitute a "buffer zone", so that the first transition section does not directly contact the heat exchange cooling section, avoiding a sharp drop in the temperature of the activated carbon in the desorption tower, thereby preventing the activated carbon from scaling on the unopened surface of the upper tube sheet in the cooling section, Prevent the clogging and corrosion of the desorption tower. At the same time, due to the setting of the "buffer zone", the situation of spontaneous combustion caused by the "bridge" activated carbon falling directly to the bottom of the desorption tower is avoided.

Description

technical field [0001] The invention relates to an activated carbon thermal analysis tower and an activated carbon analysis method, in particular to an activated carbon analysis tower device and an activated carbon analysis method for preventing fouling and activated carbon spontaneous combustion, and belongs to 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. In the desulfurization and denitrification devices including activated carbon adsorption tower and desorption tower (or regeneration tower), the activated carbon adsorption tower is used for adsorption of sulfur oxides, nitrogen, and Pollutants including oxides and dioxins, while the desorption tower is used for thermal regeneration of activated carbon.
