Hebei ** News (Reporter Feng Yang) is not only a national 3A-level tourist attraction, but also an A-level iron and steel enterprise with environmental performance, how to achieve a perfect combination? On January 31, the reporters of the "Happy Beijing-Tianjin-Hebei New Year Together" theme publicity joint interview group checked in to the Tiangang Company of Xintiangang Group in Tianjin to explore the green transformation of this old steel plant.
Walking into the factory, steel sculptures of different shapes are scattered on the lawn, showing a kind of beauty of rigidity and softness; The towering painted chimneys and the exterior walls of the factory painted with peony flowers are full of artistic atmosphere; In the tourist service center, the steel cultural and creative products designed and produced by the workers themselves come to life, and the cold steel seems to have a temperature. Tourists are in it, and a beautiful picture of the integration of production, life and ecology jumps in front of them.
From the former "big polluter" to the current 3A scenic spot, behind it is the green transformation of the enterprise.
In 2019, Delong Group implemented judicial reorganization of many enterprises such as Tiangang Group, Tiantie Group, and Metallurgical Group, and established New Tiangang Group. Since then, Delong Group has introduced the concept of "no upper limit on environmental protection investment" to Tiangang Company, promoting it to accelerate its pace on the road of green and high-quality development.
If you want to understand the environmental performance of Tiangang, you must come here. E Jianjun, chief engineer of the energy department of Tiangang Company, took reporters to the sintering workshop in the factory area.
The sintering workshop is clean and tidy. In the central control room next to the workshop, the real-time data of the sintering process is displayed on a large screen. Among them, nitrogen oxides and sulfur dioxide emissions were 202 mg cubic meters, 89 mg cubic meters.
At present, these indicators are very stable, which means that the sintering flue gas has reached ultra-low emission levels. Liu Jifeng, deputy director of the sintering workshop, said that such an effect can be achieved because of the "surgery" on the sintering machine.
In 2019, a semi-dry desulfurization device and an SCR (selective catalytic reduction) desulfurization device were successively added to the sintering machine, and a comprehensive purification process of circulating fluidized bed + bag dust removal + SCR was adopted to reduce the sintering flue gas emissions step by step.
What Liu Jifeng is most proud of is the environment outside the sintering workshop. In the "zoo" on the lawn next to the road, chickens, geese and other small animals paced freely, and a peacock hid in a heated nest to keep warm. He said: "It turns out that when you come here, you will be covered in ashes. Now, the animals are willing to live here. ”
Striving to create an A-level enterprise with environmental protection performance, Tiangang Company has made multi-directional efforts.
Overlooking the factory, rows of photovoltaic panels on the roof of the factory shine in the sun.
In April 2022, the first phase of Tiangang's rooftop distributed photovoltaic power station was connected to the grid for power generation, with an annual power generation capacity of 9 million kWh. The second phase of the project is under construction and is scheduled to be connected to the grid in August this year.
E Jianjun said: "The spontaneous self-consumption of green electricity not only offsets the quota of carbon emissions, but also saves electricity bills, and kills two birds with one stone. ”
The 100 MW ultra-high temperature subcritical gas power generation project has an annual power generation capacity of 74.4 billion kWh, reducing energy consumption by 22690,000 tons of standard coal;
More than 120 pure electric heavy trucks and 35 hydrogen heavy trucks have been invested to build a clean transportation system with trains, belts, trams and other main structures, and the proportion of clean transportation is stable at more than 80%;
The carbon manager is responsible for carbon asset management, and has established a carbon process analysis mechanism, clarifying that "solid fuel consumption, iron-steel ratio, and green electricity introduction" are the direction of carbon control and carbon reduction.
Since 2019, Tiangang Company has taken "environmental protection and low-carbon development" as the main vein of green development, started process reengineering, promoted cleaner production, and successively invested 3.7 billion yuan to comprehensively upgrade 100 organized emission sources, 1,578 unorganized emission points, and more than 10 kinds of material transportation, so as to enhance the gold content of development with industrial green content.
