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 comprises a heating section, a first transition section, a transition cooling section, a secondtransition section and a heat exchange cooling section which are arranged from top to bottom. The transition cooling section and the second transition section commonly form a buffer zone to make the first transition section not in direct contact with the heat exchange cooling section, so a sharp drop of the temperature of activated carbon in the desorption tower is avoided, thereby the activated carbon is prevented from scaling on the non-perforated surface of a tube plate in the cooling section, and the desorption tower is prevented from being clogged and corroded. The arrangement of the buffer zone avoids spontaneous combustion of bridging activated carbon directly falling to the bottom of the desorption tower.

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 spontaneous combustion of activated carbon, 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 adopt 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 to adsorb sulfur oxides and nitrogen from sintering flue gas or exhaust gas (especially the sintering flue gas of sintering machines in the steel industry) Oxides and dioxins ...
