Recently, the Ministry of Industry and Information Technology announced the list of green manufacturing in 2023, and Anhui Zongyang Conch Cement Co., Ltd., which belongs to Conch Cement , was selected as the list of green factories. So far, Conch Cement has built 27 national green factories and 21 provincial green factories. Overlooking Zongyang Conch from the air, the dense trees covering the factory area are full of greenery, rows of photovoltaic panels are arranged neatly on the Conch Lake, and the carefully planned factory buildings are in harmony with the natural environment. Next, please follow the author to explore the story behind this green factory.
Oushan is a conch limestone mine in Zongyang on the platform of + 68, where the drilling rig punctures accurately, the shovel wields the iron wall, and the limestone fragments are sent to the mine car with the soil coming out of the grass. Mine cars carrying limestone moved in an orderly manner along their respective tracks to the discharge port. "See this dirt?" Huang Ma, the head of the mine branch, crouched down and picked up a small piece of soil and said with a smile, "We adhere to the principle of" scientific, green and efficient "mining, with the use of stripping and stone, all waste soil and stone can be turned into treasure, to achieve" zero waste discharge "and make full use of mine resources."
Zongyang Conch's mine is clean and beautiful, thanks to environmental protection measures such as spraying dust, mine greening, tail gas purification, and more importantly, it depends on a strong and stable intelligent industrial brain. "In the past, mining, production and management mainly relied on people to command, and production data could not be fed back in real time, but now the digital intelligent mine system can monitor, analyze and make quick decisions in real time, and the mine car can carry out mining and transportation operat ions under the remote command of the system, which not only reduces the labor intensity of the front-line staff, but also ensures the downhill ore." The resource utilization rate is 100%. Huang Ma introduced. The "new" of
02、 is booming, the momentum of green development is surging
down from the mine, along the Rainbow Avenue in the factory area, the photovoltaic panels arranged neatly on the sparkling Conch Lake stretch out in front of us, shining in the sunshine, "in addition to the Conch Lake. Photovoltaic panels and BIPV flexible photovoltaic panels are also installed on the roof of the staff dormitory and on the raw material shed. The development of clean energy is the trend of the times, the company actively promotes photovoltaic power generation projects, the first phase of the project alone can save 870 tons of standard coal per year, reduce carbon dioxide emissions of about 4000 tons, with good economic, ecological and social benefits. As soon as the voice of Li Jiamin, the head of the preservation department, fell, the truck carrying bundles of straw passed by us, and the line of sight changed to the biomass plant of the first branch factory. "This is the first biomass alternative fuel project in the domestic cement industry, using straw instead of raw coal as industrial fuel, which can digest 150000 tons of agricultural straw annually, save 73000 tons of standard coal and reduce carbon dioxide emissions by about 200000 tons, effectively sol ving the environmental pollution and comprehensive utilization problems caused by open-air burning of local straw." Lei Youming, the head of the first manufacturing branch, talked to us.
In addition, the company also has 2000 square meters of large-scale "charging treasure"-6MW/36 MWh all-vanadium redox flow battery energy storage demonstration power station, which is the first all-vanadium redox flow battery energy storage demonstration project of Conch Group, and is also the largest all-vanadium redox flow battery user side energy storage power station in the industry. The person in charge of the project introduced to the author, "These'charging treasures' can discharge 15.84 million degrees of electricity every year, which can effectively alleviate the pressure of peak power supply and is the magic weapon for the company to meet the peak in summer!"
03、, clean factories embrace the future
, which is different from the traditional impression of dusty and noisy cement factories, walking on the clean and spacious road in the conch factory area of Zongyang, the phoenix trees with distinct seasons and the evergreen camphor trees reflect each other in the sun, and the clear and cheerful calls of birds come from the ears. It's like being in an ecological garden and forgetting the noise of the city. Even in the cold winter, the plum blossoms blooming proudly, the tall and evergreen pines and cypresses, and the squirrels and hares sticking out their heads in time all make the factory full of vitality. The perennial blue sky, green water and green hills in the
plant area are inseparable from technical transformation and environmental protection management. In recent years, Zongyang Conch has implemented the technical transformation of SCR denitrification project for all production lines, which has reduced the total annual emission of nitrogen oxides by more than 30%. Hearing birds and smelling flowers is also due to the company's continuous and comprehensive treatment of noise sources and pollutant outlets in the factory area. "In terms of water treatment, the company has built a rainwater collection system and a wastewater collection pool, which centralizes the collection and disposal of production and domestic wastewater for road sprinkling and plant greening, realizing that wastewater is not discharged; in the wharf area, we implement the closed construction of corridors and the environmental protection management of ship loaders, which improves the environmental protection management and control of material transportation links and jointly protects the spring water of the river." Standing in the green corridor beside Rainbow Avenue, Wu Jinsong, the head of the Safety and Environmental Protection Department, told the author about the efforts made by the company in improving the factory environment and promoting the green and high-quality development of enterprises in recent years. "I have been working in a cement plant for almost 40 years. In the 1980s and 1990s, I was covered with dust on sunny days and mud on rainy days. Over the years, the progress of technology, the investment of funds and the change of ideas have turned the once dusty cement plant into a garden-style factory.". In more than ten years of environmental protection work, especially in the process of creating green factories, I have a deeper understanding of "protecting the ecological environment is to protect productivity, improving the ecological environment is to develop productivity", and will continue to practice it. Wu Jinsong said firmly.
Green is the most distinctive background of high-quality development. Green manufacturing is not only an important task to achieve industrial transformation and upgrading, but also an effective way to achieve green development in the industry. It is also an inevitable choice for enterprises to take the initiative to assume social responsibility. "Being appraised as a national green factory is not only an incentive but also a spur. We will earnestly study and implement Xi Jinping's ecological civilization thought, adhere to high-quality development and high-level protection, coordinate to promote carbon reduction, pollution reduction, green expansion and growth, and run at full speed on the road of green development." Cheng Xiaobing, head of conch in Zongyang, said.
