Problems solved by technology

However, in these regeneration methods, most of the adsorbed substances in the activated carbon are forcibly replaced or released, and the treatment method is single. However, in the actual regeneration process, the activated carbon with saturated adsorption is mainly divided into hazardous solid waste activated carbon and general solid waste activated carbon, and according to The state of activated carbon is divided into honeycomb, granular and powder, so there is a need for an efficient, energy-saving and environmentally friendly regeneration method for waste activated carbon

Abstract

The invention discloses an efficient, energy-saving and environmentally-friendly waste activated carbon regeneration method. A system for implementing the method comprises a feeding system, a regeneration system, a discharging system, a combustion system, a flue gas purification system and a waste heat recovery system. A to-be-regenerated material is put into a feeding hopper, and is fed into a closed stock bin through a bucket elevator and a scraper; the material in the closed stock bin enters a regeneration furnace through a screw feeder, and is regenerated, small amounts of air and water vapor are introduced, and exhaust gas adsorbed by waste activated carbon is desorbed at a high temperature, and reacts with oxygen to generate water vapor and carbon dioxide gas. Compared with the priorart, the efficient, energy-saving and environmentally-friendly waste activated carbon regeneration method of the invention has the characteristics of flexibility, convenience, high utilization rate,high pertinence for the regeneration process of saturated activated carbon with different properties and forms, high efficiency, energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of activated carbon regeneration, more specifically, it relates to a high-efficiency, energy-saving and environment-friendly regeneration method for waste activated carbon. Background technique [0002] Activated carbon is a substance with a wide range of uses, and has a wide range of applications in deodorization, decolorization, and anti-virus. The industrial or civil field mainly uses the porous adsorption capacity of activated carbon to selectively adsorb certain substances in the gas phase or liquid phase system, and then separates them from the system. For example, in gas masks and activated carbon masks, the adsorption properties of activated carbon are used to selectively adsorb harmful substances in the air, thereby achieving the purpose of air purification. Another example is the selective adsorption of activated carbon for decolorization in the food industry. Activated carbon is also widely used...
