great achievements in energy conservation and emission reduction of Pingdingshan WISCO combined coking during the 11th Five Year Plan period

China engineering machinery information

Guide: since the 11th Five Year Plan period, Wuhan Pingdingshan WISCO combined Coking Co., Ltd. (hereinafter referred to as Pingdingshan WISCO 2, the principle of traditional power line zigzag testing machine and the principle of traditional power line zigzag testing machine combined coking) has vigorously promoted energy conservation and emission reduction with remarkable achievements. Pingmei WISCO United coking is a subsidiary of WISCO. At present, the production scale has ranked first among independent coking companies in China

since the 11th five year plan, Wuhan Pingmei WISCO United Coking Co., Ltd. (hereinafter referred to as Pingmei WISCO United coking) has made great efforts to promote energy conservation and emission reduction, with remarkable achievements. Pingmei WISCO United coking is a subsidiary of WISCO. At present, its production scale has ranked first among independent coking companies in China, and its technical equipment is at the leading level in China

in recent years, with the increasing requirements of national environmental protection, energy conservation and emission reduction policies, the company is facing unprecedented pressure on energy conservation and emission reduction. Weisongbo, general manager of Pingdingshan Coal and Wuhan Iron and Steel Co., Ltd., said in an interview with this newspaper that in view of this situation, the company has put forward the goal of "ten indicators are better than the design demand and the first five" energy conservation and emission reduction: to achieve the national first-class level of energy consumption indicators in coking process, and finally achieve negative energy production; Ensure that the total amount of pollutants discharged reaches the total amount control index approved by the local government and the group company, and meets the regional environmental quality requirements. The standard rate of wastewater discharge is 100%, and the recovery and utilization rate of process waste residue is 100%

in order to achieve this goal, the company has taken the following measures:

first, adhere to management innovation and technological innovation. Adhere to the principle of "reduction, reuse and recycling", adhere to management innovation and technological innovation, and actively promote energy conservation and emission reduction measures. By establishing and implementing the energy conservation and emission reduction work system and accountability system, implementing the self-restraint mechanism, and carrying out in-depth activities such as "benchmarking and tapping the potential", the main indicators such as material consumption, energy consumption, water conservation, environmental protection and comprehensive utilization are comprehensively "benchmarked" with the advanced level of domestic and foreign enterprises of the same type

second, strengthen source control and process control. The dry coke quenching process has been recognized by the coking industry in China. It is an advanced coking process to save energy, protect the environment and improve the coke quality for the convenience of installation. At present, the company has 5 sets of large-scale CDQ devices, with a CDQ rate of 98.7%, a CDQ dust removal efficiency of 99%, and a dust concentration of less than 20mg/m3 at the discharge outlet, greatly reducing the amount of toxic and harmful substances discharged to the region. At the same time, two 70 hole 7.63m super large coke ovens were put into operation in March 2008, providing a solid technical support for energy conservation and emission reduction

third, implement key projects of energy conservation and emission reduction. The company needs to consume nearly 7million ~ 8million tons of coal washing for coke production every year. For a long time, the company has been facing the constraints of raw coal resource shortage and environmental pressure. In recent years, the company has eliminated three 4.3m coke ovens with small capacity, large energy consumption and pollution, invested more than 3 billion yuan to rebuild and expand four large modern new coke ovens, and built the largest and most advanced 7.63m coke oven in Asia

it is reported that after years of efforts, the combined coking of Pingdingshan Coal and WISCO has achieved remarkable results in energy conservation and emission reduction: the water consumption has decreased from 5.81t/t coke in 2005 to 3.25t/t coke, and the water recycling utilization rate has reached 95%; The purchased steam is reduced from 0.27t/t coke in 2006 to 0.12t/t coke; The energy consumption of comprehensive process decreased from 133.72kgce/t coke in 2005 to 125.77kgce/t coke, and the energy consumption of comparable coking process decreased to 101.4kgce/t coke, reaching the leading level in the same industry; Compared with 2006, the smoke and dust emission was reduced by 377 tons/year, the solid waste residue was zero discharged, and all indicators of biochemical external drainage reached the national level I emission standard

at the same time, through the realization of energy conservation and emission reduction goals and the implementation of energy conservation and emission reduction projects, the company has achieved a cost reduction of about 20million yuan. On November 29 this year, the first 7m large-scale coke oven was completed and put into operation ahead of schedule on March 5, marking that Pingdingshan WISCO United coking company has leapt to a new level in energy conservation and emission reduction
