Abstract

The invention relates to the technical field of activated coke regeneration, and discloses an activated coke regeneration system and regeneration method. The system comprises: a regeneration device, wherein the regeneration device comprises a heating section, an analysis section and a cooling section which are sequentially arranged from top to bottom; a first conveying sleeve, which comprises a first inner pipe and a first outer pipe, wherein the first inner pipe is sleeved with the first outer pipe, a circulation channel is formed between the first inner pipe and the first outer pipe, the two ends of the first outer pipe communicate with an inlet of the heating section and an outlet of a heater correspondingly, and the first inner pipe is communicated with an outlet of the analysis section; a dust remover, which is communicated with the first inner pipe; and a second conveying sleeve, which comprises a second inner pipe and a second outer pipe. The conveying pipeline is arranged to be a sleeve, meanwhile, the heat source of the regeneration system is used for heating a regeneration gas pipeline, and the phenomena of corrosion and blockage of the analysis section and the conveying pipeline due to regeneration gas condensation are avoided.

Description

technical field [0001] The invention relates to the technical field of active coke regeneration, in particular to an active coke regeneration system and a regeneration method. Background technique [0002] Coal is currently the main fossil energy source in my country. During the combustion process of coal, SO 2 form release. Activated coke dry desulfurization technology is a desulfurization technology that can be resourced. The activated coke saturated by adsorption can be regenerated by heating or washing with water, and the SO 2 with sulfuric acid or liquid SO 2 form is recycled. [0003] The regeneration tower heats and regenerates the activated coke used to purify the flue gas. The activated coke flows through the heating section, the analysis section, and the cooling section from top to bottom to restore its activity, and then resolves the regeneration gas with high concentration of sulfur dioxide in the analysis section. The regeneration gas is discharged and recov...
