Device and method for regeneration of powdered activated carbon

Abstract

The invention discloses a device and a method for regeneration of powdered activated carbon. The device comprises a furnace body, wherein a retractable furnace door is arranged on the furnace body; an internal hollow hearth is arranged inside the furnace body; insulating layers are arranged at the four walls and the periphery of the top part of the hearth; heating wires are embedded in the insulating layers. The device is characterized by also comprising an exhaust and tail gas combustion treatment system, an intake valve, a bracket structure, more than one drawer-type box body and a gas outlet valve, wherein the bracket structure is fixedly arranged inside the hearth; the drawer-type box body is detachably arranged on the bracket structure; the exhaust and tail gas combustion treatment system is fixedly arranged at the top part of the furnace body; the intake valve is fixedly arranged at the top of the furnace body; the gas outlet valve is fixedly arranged at the bottom of the furnace body. Compared with the prior art, the regeneration treatment efficiency can be greatly improved, energy consumption and time are saved, and the operation is simple and feasible.

Description

technical field [0001] The invention belongs to the field of industrial equipment and technology, and relates to a device and method for regeneration of powdered activated carbon, in particular to a device and method for regeneration of powdered activated carbon after deactivation of industrial wastewater. [0002] Background technique [0003] Activated carbon has a highly developed pore structure and objective specific surface area, and has a strong adsorption capacity for a variety of molecules. It is an excellent adsorbent. It is currently used in the advanced treatment of urban sewage, industrial wastewater and the purification of polluted water sources. widely. 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. [0004] At present, the regeneratio...
