Wanji Graphite Company implements environmental protection transformation to promote green development

Recently, Wanji Holding Group Graphite Products Co., Ltd. (hereinafter referred to as “Wanji Graphite Company”) has completed and put into operation the graphitization furnace flue gas treatment and environmental protection transformation project. The concentration of industrial waste gas sulfur dioxide and smoke dust particles all meet the ultra-low emission requirements, and the environmental protection benefits are significant. , The social benefits are outstanding, the economic operation quality and benefits are improved, and the space for investment value is high.
Wanji Graphite Company broke the foreign technology blockade in 2005 and built the first domestic large-scale professional production line of graphitized cathodes for Aluminum, with an annual output of 50,000 tons of graphitized cathodes. Wanji brand graphitized cathode has good electrical conductivity, thermal conductivity, thermal shock resistance, thermal expansion, corrosion resistance and other properties. The aluminum electrolytic cell constructed with this graphitized cathode has a life span of more than 3 years than ordinary electrolytic cells. In addition to meeting the needs of the domestic market In addition, it is also sold in batches to internationally renowned aluminum companies such as Alcoa, Alcoa, Brazil, Venezuela, Iceland, Hydro, and Dubai.
In recent years, Wanji Graphite Company has taken green standards as the lead and focused on green transformation. It has successively carried out environmental protection treatment and transformation on various production processes, strengthened the promotion and application of energy-saving and environmental protection technologies, processes, and equipment, strengthened product life-cycle green management, and accelerated Promote circular economy and comprehensive utilization to achieve high-efficiency, clean, low-carbon, circular and sustainable industrial development. In August 2020, the company invested more than 30 million yuan to upgrade the standard of the flue gas generated by the graphitization furnace. The project has advanced technology and created a precedent in the domestic internal string graphitization furnace flue gas desulfurization transformation. It is an important measure of Wanji Graphite Company to increase the green transformation and an important starting point for improving the level of industrial green development.
The environmental protection transformation project of Wanji Graphite Company’s graphitization furnace flue gas treatment includes two sets of lime-gypsum desulfurization systems and a set of sewage treatment systems, and newly added dust collecting hoods, dust collecting hood steel brackets, exhaust fans, desulfurization towers, and wet electric dust removal The main equipment such as electrical equipment, online monitoring system, etc., is mainly to construct 1#, 2# flue gas desulfurization and dust removal systems on the south side of the 2 graphite chemical sections, and a set of wastewater treatment systems on the south side of the 1# graphite chemical section To treat the wastewater discharged from 2 sets of desulfurization and dust removal systems. The 1# desulfurization and dust removal system processes the flue gas produced by the graphitization furnaces of the graphitization cathode production line 1#, 2#, and 3# with an annual output of 20,000 tons, with a processing air volume of 150,000 cubic meters per hour. The 2# desulfurization and dust removal system treats the flue gas produced by the graphitization furnace in the 4# and 5# sections of the graphitized cathode production line with an annual output of 30,000 tons, and the processing air volume is 110,000 cubic meters per hour. 1#, 2# desulfurization and dust removal wastewater is treated by the wastewater treatment system.
It is reported that since Wanji Graphite Company’s graphitization furnace flue gas treatment and environmental protection transformation project was put into operation, it has reduced the production shutdown and production restrictions caused by environmental protection control, so that production can continue and stably run, orders can be delivered smoothly, and the company’s market has been improved. Competitiveness has increased the depth and breadth of cooperation between domestic and foreign customers, especially in the heating season, it will reduce the loss of production and production restrictions, and increase business income by more than 90 million yuan and profits and taxes by more than 5 million yuan.
