On March 23, the General Office of the Ministry of Industry and Information Technology announced the list of green manufacturing in 2022, and China Resources Cement (Anshun) Co., Ltd. (Hereinafter referred to as "Anshun Cement") was listed in the list of green factories. Up to now, China Resources Cement has successfully established 11state-level green factories, the green factory camp continues to expand, and the speed of transformation and development is improving in an all-round way.
01 Play a good green card, interpret the original intention
of development with action, Anshun Cement has always firmly established and practiced the concept of "green water and green hills are Jinshan and Yinshan", and unswervingly take the road of green development of energy saving, emission reduction and ecological priority; It is committed to promoting clean production and comprehensive utilization of energy, and striving to build environment-friendly, resource-saving and green recycling factories.
The company has set up a leading group for the construction of green factories, which has passed the certification of environmental management, energy management, occupational health and safety management and quality management system, and all environmental protection indicators have maintained the leading level in the industry. It has successively won the honorary titles of "People's Enterprise of Xixiu District of Anshun", "Advanced Collective of Electric Power Low Carbon Trading in Guizhou Province", "Honest Industry and Credit Enterprise in Guizhou Province", and interpreted the original intention of "Green Development Ecological Cycle" with practical actions. The administrative building
of
the factory area 02 promotes the comprehensive utilization of resources and forms a green recycling industry chain
. Anshun Cement has made continuous efforts in the comprehensive utilization of resources, building a first-class energy-saving unit and promoting energy-saving technological transformation, and has achieved remarkable results in energy-saving and consumption-reducing articles. In the aspect of making full use of
resources, we should make full use of industrial solid wastes such as phosphogypsum, fly ash, smelting, mining and mineral processing waste residues, coal gangue, coal-fired slag and yellow phosphorus slag to produce cement, so as to reduce the pollution and land occupation caused by the stacking of waste residues, at the same time, reduce the utilization rate of raw ore and reduce the ecological damage caused by mining and transportation. To achieve both environmental and economic benefits. In terms of building a first-class energy-saving unit on the exterior
of Anshun Cement Plant, Anshun Cement has been continuously carrying out energy-saving and consumption-reducing related work since it was put into operation in February 2020, such as using yellow phosphorus slag, wet fly ash, roasting coal gangue composite ingredients, using biomass particles, sawdust and other biomass fuels to replace part of the raw coal, so as to save energy. Waste tire oil is used to replace diesel oil. As of December 31, 2022, the comprehensive energy consumption per ton of clinker has reached the first-class energy consumption level, with an annual consumption of more than 1000 tons of biomass alternative fuels and more than 40000 tons of coal-fired slag. In the aspect of
promoting energy-saving technical transformation, by optimizing the energy-saving technical transformation of the fan motor of the circulating water cooling tower for waste heat power generation and the resistance of the AQC waste gas pipeline, the comprehensive unit power consumption can be reduced by about 0.3 kwh/t, and the annual power consumption can be saved by about 600,000 kwh.
03 Take multiple measures to strengthen energy conservation and emission reduction, promote green cycle and low carbon path
in "green development & nbsp;" Under the guidance of the concept of "circular economy", Anshun Cement strictly implements the principle of "reduction, reuse and recycling" in the production and operation process, controls the consumption of resources in the production process, strengthens the emission reduction of atmospheric pollutants and noise control, and the emission of major pollutants is far below the national standards. In terms of
upgrading the system to reduce the emission of major pollutants, the production line is equipped with a set of SNCR denitration system and 85 bag-type dust collectors simultaneously to achieve the source emission reduction of the process and equipment; actively implement the national "double carbon" strategy, and actively adopt the method of ingredients + alternative fuels from 2021, with a cumulative reduction of more than 390,000 tons of carbon emissions; In 2023, a set of SCR system will be upgraded and built to further reduce the emission of major pollutants and make sustained efforts to ensure the reduction of total emissions. In the aspect of
strengthening the control of unorganized dust, through a series of measures such as increasing the frequency of spraying on main roads, configuring the spraying system for feeding in key parts, and carrying out technical renovation of the company's internal dust collector, the control of unorganized dust has been strengthened to achieve the advancement from standard emission to ultra-low emission. In the aspect of
strengthening noise control by spraying dust on
mine roads, noise control is strengthened by installing sound insulation boards, sound insulation doors, sound insulation windows or silencers, so as to effectively prevent and control noise pollution in mine crushing, cement mill, cement mixing station, Roots blower at the bottom of cement reservoir, dust collector blower and other parts.
Plant noise control
04 Looking forward to the future development and accelerating the pace of
green transformation, Anshun Cement, in accordance with the spirit of the national energy "double control" document, closely follows the national energy saving and emission reduction strategy, continues to carry out the application of new technologies. The energy consumption meets the requirements of the Energy Consumption Limit for Cement Unit Products GB16780-2021 ahead of schedule, and is in the leading position in the industry. In the future, the company will continue to explore carbon reduction measures, further control the intensity and total amount of carbon emissions, and firmly promote the effectiveness of various work.
Anshun Cement will cooperate with the national carbon peak action step by step in a planned way, so as to combine the development of enterprises with the protection of the ecological environment, promote the formation of a green and low-carbon production and lifestyle by improving the matching of the ecological environment, ensure the greening, purification, beautification and brightening of the factory area, and create a vibrant environment for employees. Build a harmonious, warm and fascinating life home.
Factory Panorama
Anshun Cement thoroughly implements the idea of green development, combining enterprise development with ecological environment protection. At the same time, in order to further promote the green, digital and intelligent development of the cement industry, China Cement Network will be launched on April 24-25, 2023. The "China Cement Industry Green Development Summit Forum and Ultra-clean Emission Technology Exchange Conference" and the "Fourth China Cement Intelligent Summit Forum" were held in Changsha, Hunan Province, inviting industry experts, cement and related enterprises. Jointly promote the high-quality development of the cement industry! After the meeting, we will visit Sinoma Zhuzhou Cement Co., Ltd. and the first set of international "one-box SCR denitrification project of dust and nitrate".
