Novel multi-pipe external-heating revolving activation furnace

Abstract

The invention discloses a novel multi-pipe external-heating revolving activation furnace, and solves the problems of poor activating effect, low yield, easy fracture and the like in the conventional revolving activation furnace. The activation furnace comprises a furnace body, a drive device, a discharge device, a heating furnace, a funnel and the like, wherein the furnace body consists of a plurality of heat-resisting seamless stainless steel pipes and cylinders positioned at the two ends; shovelling plates and steam pipes are arranged in the heat-resisting seamless stainless steel pipes; one end of the furnace body is connected with a feeding / exhaust device through a sealing device; and the other end is connected with the discharge device. The novel multi-pipe external-heating revolving activation furnace stops dangerous elements such as welding stress, changes the phenomenon of overmuch coal material accumulation so that coal materials can be uniformly distributed in a plurality of activation pipes, enlarges the heating area of the coal materials, completely collects and recycles combustible gases produced during the activation, protects the environment, saves energy, has a simple structure, and can greatly prolong a manufacturing cycle and reduce processing cost.

Description

Technical field [0001] The invention relates to equipment in the field of activated carbon production, more specifically to a rotary kiln with a new structure specially used for activation treatment of activated carbon. Background technique [0002] At present, the furnace types used in the production of activated carbon are two types of rotary activation furnaces: internal heating type and external heating type, which have the advantages of simple structure and easy operation. However, due to the use of refractory bricks and insulation materials in the internal heat rotary activation furnace, some problems often occur during production and operation. For example, refractory bricks and insulation bricks are used in the lining to make the furnace body too heavy, resulting in high power consumption. At the same time, due to the expansion caused by high temperature and the vibration during rotation, the refractory materials in the furnace often loosen. This loosening phenomeno...
