Recently, the Ministry of Industry and Information Technology announced the list of green manufacturing in 2022, and Yicheng Company (hereinafter referred to as "Yicheng Cement Company"), a subsidiary of China Gezhouba Cement Company, was successfully selected as the "National Green Factory" list.
Green is the background of high-quality development. The report of the 20th National Congress of the Communist Party of China put forward the idea of "accelerating the green transformation of development mode", emphasizing the promotion of green and low-carbon economic and social development. Yicheng Cement Company actively responds to the call, adheres to the concept of green development, promotes the implementation of China's "1466" strategy, integrates "intellectualization" and "digitalization" into production and operation, improves the green manufacturing system, and contributes to the green manufacturing force to promote the high-quality sustainable development of enterprises.
In order to solve the problem of urban and rural domestic waste treatment
, Yicheng Company
combines the raw material treatment and high temperature calcination process in the new dry precalcining technology of cement industry, adopts the international advanced domestic waste pretreatment technology, and adopts the advanced domestic waste pretreatment technology. A daily disposal line of 200 tons of urban and rural domestic waste has been built.
Yicheng Company Cement Kiln Co-disposal Project
"In the past, rural garbage was dumped at will, and landfills were collected in towns and cities, but landfills not only occupied land, but also environmental problems were not easy to deal with, especially in summer, the smell was particularly strong.". I went to the scene to see the collaborative disposal of garbage line, which is a relatively safe and ideal way of disposal. After a delegation of the Yicheng People's Congress investigated the disposal of garbage in the enterprise, a representative living in the original landfill was amazed.
It is reported that the company can dispose of more than 60000 tons of municipal solid waste in Yicheng City annually, which ensures the "harmlessness, reduction and resource utilization" of municipal solid waste disposal in Yicheng City, contributes to the development of circular economy in Yicheng City, improves the urban environment, and has good social and environmental benefits.
Precise control of pollutant emissions
is to make full use of waste heat resources generated by cement production lines, save energy, reduce consumption, reduce waste gas and pollutant emissions, and adhere to the new industrialization road of scientific and green development. The company has built a pure low-temperature waste heat power generation project with an installed capacity of 9.0 MW and a production line flue gas denitrification (SNCR) technology transformation project, which reduces 45000 tons of carbon dioxide, 300 tons of sulfur dioxide and 900 tons of nitrogen oxides to the atmospheric environment every year. The environmental protection facilities are equipped with high-efficiency dust collectors, and the dust removal efficiency reaches 99.9%. In the aspect of material storage and transportation, closed equipment and closed storage are adopted to reduce the drop of material transfer and effectively eliminate the phenomenon of scattered discharge.
"During the period of peak staggering and kiln shutdown this year, while carrying out energy-saving and carbon-reducing technological transformation, we also upgraded waste heat power generation and flue gas denitrification to further improve the efficiency of waste gas recovery and waste heat utilization and reduce nitrogen oxide emissions." At the overhaul site, the company's production manager introduced the plan and target of the two-month shutdown overhaul.
Opening up a new path
of green development, distributed photovoltaic power generation project is another important measure for the company to explore green development, transformation and upgrading. The project does not occupy land resources, make full use of the top of the roof building in the plant to build photovoltaic power generation equipment, the installed capacity of photovoltaic power station is 4.95 MW, using the way of "self-use, surplus electricity access to the grid" to access the grid, providing 4.6442 million degrees of clean electricity annually, saving 1310 tons of standard coal annually. Smoke and dust emissions were reduced by 14.64 tons, sulfur dioxide emissions by 37.29 tons and nitrogen oxide emissions by 32.04 tons. The successful grid-connected power generation of the
project marks the vivid practice of accelerating the green development of China Gezhouba Cement Company, successfully contributing to the goal of "double carbon" and accelerating the pace of green low-carbon transformation.
In 2020, our Huzui-Matoushan mining area was successfully selected into the national green mine directory database, Huangniushan mining area was selected into the green mine directory database of Hubei Province, and the two mining areas were deeply integrated into the surrounding landscape, which added to the green development of enterprises. It has added new impetus to local economic development. The head of Yicheng Cement Company introduced.
In product development and design, the company adheres to high starting point positioning, high standard planning, high requirement implementation and high efficiency supervision, and strives to create environmentally friendly and resource-saving green environmental protection products, such as P · C 42.5 cement, which has good workability and impermeability. With good early strength and stable strength growth, it is suitable for various civil and industrial buildings such as bricks, tiles and plates. M3 2.5 cement has the advantages of small water demand, small bleeding and high water retention. The prepared concrete has good volume stability and is widely used in masonry, mortar plastering and cushion concrete construction. The company's products have been applied to Xiangyang East-West Axis Immersed Tunnel, Lanzhou-Xinjiang Railway, Hanshi high-speed rail, Xiangyang Third Bridge, Mazhu Expressway, Guzhu Expressway, Xichuan Section of South-to-North Water Transfer Middle Line and other key projects, as well as surrounding commercial and mixed buildings and civil projects, and are favored by customers.
"When the sky is blue, the water is clear, the environment is beautiful, and the surrounding residents and the public are satisfied, our work will be meaningful." The head of the company said confidently. It is understood that while being selected as a national "green factory", P.O42.5 cement of Yicheng Company and P.O42.5 cement of Laohekou Company, which belong to Gezhouba Cement Company, were successfully selected as "national green design products". Green water and green hills in the factory area
of Yicheng Company are Jinshan and Yinshan. China Gezhouba Cement Co., Ltd. will actively implement the "double carbon" goal, implement the new development concept, further consolidate the foundation with the most comprehensive management system, the strictest working attitude and the most scientific production process, implement the social responsibility of the central enterprises, unswervingly take the road of green development, promote green manufacturing, build green factories and lead the development of the industry with the concept of circular economy development.
