Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, specifically a waste gas treatment device for a graphite electrode calcining furnace. Background Technology

[0002] Graphite electrodes are high-temperature resistant inorganic non-metallic materials made from petroleum coke and pitch coke as aggregates and coal tar pitch as a binder. The process involves calcination, crushing and grinding, batching, mixing, molding, roasting, impregnation, graphitization, and machining. Graphite electrodes are a relatively common new energy material. The roasting process of graphite electrodes generates a large amount of waste gas, which needs to be treated by a processing device. However, existing waste gas treatment devices require filter media to neutralize harmful substances in the waste gas. These filter media are consumables and need to be replaced regularly, but the filter media installed inside the treatment box is inconvenient to replace, affecting the waste gas treatment efficiency. Furthermore, the waste gas needs to be filtered through a filter hood to remove dust, which easily clogs the filter hood and affects the airflow speed. Therefore, improvements to the existing technology are needed. Utility Model Content
