[0002] Graphitization furnace is a device used to graphitize carbonaceous materials. The main features include: High temperature environment: a very high temperature needs to be reached to achieve the graphitization process. Good thermal insulation performance: reduce heat loss and ensure stable temperature in the furnace. Accurate temperature control: ensure the quality and effect of graphitization. Working principle: under high temperature and specific atmosphere conditions, the crystal structure of carbonaceous materials is transformed, gradually transforming from disordered non-graphite structure to graphite crystal structure. Classification: Acheson graphitization furnace: a traditional and widely used type. Internal heating graphitization furnace: has the advantages of relatively low energy consumption. Graphitization furnace plays a key role in the production of graphite electrodes, graphite products, etc. The electrical conductivity, thermal conductivity, lubricity and other properties of carbonaceous materials can be significantly improved through graphitization treatment, thereby meeting the needs of different fields.
[0003] Sulfur dioxide treatment equipment is specially used to reduce or remove sulfur dioxide (SO 2 ) content. These devices use various technologies and principles to achieve the treatment of sulfur dioxide, the common ones include: wet desulfurization equipment: such as limestone-gypsum desulfurization equipment, which uses alkaline absorbents (such as lime slurry) to react chemically with sulfur dioxide for absorption treatment. Dry desulfurization equipment: such as activated carbon adsorption equipment, which adsorbs sulfur dioxide through activated carbon. Semi-dry desulfurization equipment: combines the characteristics of dry and wet methods, including spray drying desulfurization equipment. Catalytic oxidation equipment: can catalytically oxidize sulfur dioxide into substances such as sulfuric acid for subsequent treatment. The main purpose of sulfur dioxide treatment equipment is to reduce the pollution caused by sulfur dioxide emissions into the atmosphere and protect the environment and human health.
