Weichai group: energy saving management opens up Xintiandi to increase benefits

China Construction Machinery Information

Guide: as a leading internal combustion engine enterprise in China, Weichai group produced nearly 2million engines during the Eleventh Five Year Plan period, an increase of 177% over the tenth Five Year Plan period. However, through energy saving management, the company saved 334000 tons of standard coal, The comprehensive energy consumption of 10000 yuan output value is 0.0513 tons of standard coal/10000 yuan, which is lower than that during the Tenth Five Year Plan period

as a leading internal combustion engine enterprise in China, Weichai group produced nearly 2million engines during the 11th Five Year Plan period, an increase of 177% over the 10th Five Year Plan period. However, through energy-saving management, the company saved 334000 tons of standard coal, and the comprehensive energy consumption per 10000 yuan output value was 0513 tons of standard coal/10000 yuan, a decrease of 63% over the 10th Five Year Plan period

"building resource-saving and environment-friendly enterprises is an important focus to accelerate the transformation of economic development mode, and strengthening energy-saving management is one of the important ways." Said tanxuguang, chairman of Weichai group

the elimination of backward and high-energy consuming technologies and equipment is the focus of energy conservation and emission reduction management of enterprises. During the 11th Five Year Plan period, Weichai Group invested more than 5million yuan to complete the elimination and transformation of three coal-fired boilers with a gross tonnage of 10 tons, and newly installed two gas-fired steam boilers, saving more than 280 tons of standard coal per year, effectively reducing the emission of smoke and sulfur dioxide

actively implement energy-saving technological transformation and continuously tap energy-saving potential. Weichai group effectively adjusted the distribution layout of steam pipes, updated pipe insulation materials, and continuously optimized the pipe structure of steam peek 3D printouts according to the production demand and the current situation of steam supply and consumption. During the "Eleventh Five Year Plan" period, nearly 2million yuan was invested to implement automatic frequency conversion transformation for industrial boilers and automatic regulation transformation for water supply, temperature, etc. for exchange stations, with a power saving rate of 30% and a coal saving rate of 8%

small light bulbs are also included in the energy-saving management. Weichai uses LED light source to replace traditional metal halide lamps, with a power saving rate of more than 65%, so it can save more than 23million kwh per year

in addition to replacing energy consuming equipment, there is a greater potential for energy conservation through system management. Weichai has invested 37million yuan to install system power saving devices, with a power saving rate of 12%, saving more than 4million kwh per year. The lighting system of the new industrial park is installed with Reiss lighting power-saving control device, which can save more than 13% power without reducing the internal illumination of the workshop. More than 2million yuan was invested to install frequency converter in the air compressor station, with a power saving rate of 1416 Before the pendulum impact testing machine test, it is necessary to comprehensively check whether each mechanism is normal by more than%. In each production plant and energy pipe, frequency conversion and speed regulation devices are installed through the feed pump, and the power saving rate reaches 20%

the regeneration and reuse of industrial wastewater is a long-term and lasting work of Weichai to protect the ecological environment and implement circular economy

in the new industrial park, a wastewater regeneration and reuse system with a daily treatment capacity of 1000 tons has been built. The advanced process of quality based pretreatment and comprehensive treatment has been adopted. 360000 tons of reclaimed water and 360000 tons of fresh water have been recycled annually. The reclaimed water after treatment is widely used in the commissioning circulating water, production process water, toilet flushing water, fire water, etc. of the major series of diesel engines in the enterprise

Weichai pays special attention to the energy conservation and emission reduction infrastructure of the new project. During the 11th Five Year Plan period, Weichai group built four new industrial parks in Weifang, covering an area of more than 3000 mu. Taking the Foundry Industrial Park as an example, the low-energy and energy-saving production facilities are fully selected in the process design, and the waste heat utilization technology is adopted. The cupola high-temperature flue gas waste heat utilization system and steam condensate recovery system are installed, and the waste heat and waste energy are recycled to effectively reduce the heating steam and natural gas consumption in the park. Using the fully sealed bag dust removal technology, the dust removal rate can reach 99.8% of the simple production process
