Reactive coke regeneration tower

Abstract

The invention relates to a reactive coke regeneration tower. The reactive coke regeneration tower comprises a loading section, a heating section, a cooling section and an unloading section which are in sealed connection sequentially from top to bottom and are arranged in a shell body, wherein a plurality of material through pipes are vertically arranged in the heating section; and a plurality of baffle plates, which separately sleeve all the material through pipes, are further distributed in the heating section, a gap is reserved between at least one side of each baffle plate and the internal wall of the shell body of the heating section and serves as an air outlet, and thus, hot air with the temperature of 300 DEG C to 450 DEG C is subjected to repeated diversion in the shell body of the heating section and then flows out to carry out heating on reactive coke in the material through pipes. Due to the baffle plates, a circulating path of heat-exchange air in the heating section is prolonged, the efficiency of heat exchange is increased under equivalent conditions, and thus, the heat exchange is more thorough.

Description

technical field [0001] The invention relates to a device for desorbing active coke that has adsorbed sulfur dioxide, nitrogen oxides and heavy metals to restore the performance of the active coke, in particular to an active coke regeneration tower. Background technique [0002] my country's primary energy is mainly coal, and the flue gas and waste gas discharged from coal-fired power plants, metal smelters, coal-fired boiler plants, waste incineration and other industrial furnaces contain SO 2 , SO 3 , NO, heavy metal ions, harmful soot pollutants, resulting in serious pollution, affecting our production and life, the situation is very grim; since the 1970s, sintering flue gas desulfurization and denitrification technology of iron and steel plants has gradually developed in Japan and some parts of Europe The country enters industrial application. Activated coke desulfurization is a dry desulfurization and denitrification technology based on the principle of physical-chemic...
