Abstract

The invention discloses a system and method for powdered activated carbon regeneration through microwaves. The system comprises a material container, a material conveying device, a material loading device and a microwave regenerating device. The powdered activated carbon regeneration method disclosed by the invention integrates drying, carbonization and decomposition as well as activation in the system through a microwave regenerating furnace, and works together with the material conveying device and the material loading device, so as to reduce the lifting carbon black in a powdered activated carbon loading process. The system and the method can improve the regeneration efficiency, save the energy consumption and reduce the cost.

Description

technical field [0001] The invention belongs to the field of industrial equipment and technology, and relates to a system and method for regenerating powdered activated carbon, in particular to a system and method for regenerating powdered activated carbon by using microwaves. Background technique [0002] Activated carbon is a kind of adsorption material with well-developed pore structure, large specific surface area, non-toxic and odorless, and strong adsorption capacity for molecules. It is currently widely used in the advanced treatment of urban sewage, industrial wastewater and purification of polluted water sources. If the used activated carbon is not recycled, it is not only a waste of resources, but also causes secondary pollution to the environment. Therefore, from the perspective of economy and environmental protection, the regeneration of activated carbon is of great significance. [0003] Activated carbon regeneration refers to the process of removing the adsorba...
