A LWS430 three-phase horizontal spiral unloading and settling centrifuge for coal tar production and other fields was successfully developed by Haishen Electromechanical Plant and began to be used in coking coal chemical fields in batches last week. Experts said that the equipment has a wide range of applications and meets the requirements for the separation of solid-liquid-liquid three-phase materials in coal tar, and has good corrosion resistance and stable performance. Involute planetary gear differentials can be used for stepless adjustment. The water content of the tar can be freely set after centrifugation, and the light and heavy liquid phase depths can be adjusted separately, which has wide application value in the field of coking and other fields. According to Li Zhenwei, a senior engineer of Haishen Company, the new product is mainly aimed at the separation of solid-liquid-liquid three-phase materials with a certain proportion of difference. The processing capacity of the centrifuge is 13 tons/hour. After the separation, the solid content of tar (above 100μm) is less than or equal to 0.3%, which is the same as foreign advanced technology. The moisture content of the separated tar is between 0.8% and 2.0%, which is better than foreign advanced equipment. Tested by Hefei General Mechanical and Electrical Products Inspection Institute, this product complies with JB/T502-2004 "Helix unloading settling centrifuge" standard, which is well reflected by users. It is understood that in most coking plants in China, the separation of coal tar, crude ammonia, and coke slag is still treated with traditional mechanized ammonia clarification tanks, and the quality of coal tar treated is low. To improve the quality of coal tar, To remove crude ammonia and coke residue, other equipment or processes must be used, and very few manufacturers use expensive imported three-phase separation equipment. Yang Wenyu, executive deputy secretary-general of the China Coking Industry Association, said that the product can be used in the coal chemical industry to efficiently centrifuge the three-phase mixture of coal tar, crude ammonia water and coke slag, and significantly improve the quality of coal tar and other products. It should be increased in the future. Promotion efforts. At present, the centrifuge has been successfully used in coke plants such as Qian'an Zhonghua Coal Chemical Co., Ltd. and Baohua Carbon Black (Guiyang) Co., Ltd. In the second session of the coking industry's chemical products technology exchange meeting held in late May, many coking enterprises in Shandong, Jiangsu, Henan, Hebei, Inner Mongolia and other places expressed their cooperation intentions.
