Punch in National "Green Factory"-Donghua Technology

▲ Donghua Science and Technology

enters Donghua Science and Technology Company with the title of "National Green Factory". The roads in the factory area are clean and spacious, and the trees are lined up and full of vitality, which is quite different from the dusty and dusty cement enterprises in the imagination of ordinary people. In the clean and tidy production site

of Donghua Science and Technology, the road surface is wet, and the air quality is better than that of the city park. In such a good environment, there is no sprinkler passing by. It turns out that they have a magic weapon for automatic dust reduction-fog forest system. When the concentration of PM10 in the plant area exceeds the set value, the automatic spraying system and fog system in the material yard will automatically start spraying and dust reduction.

▲ Donghua Science and Technology completed the first medium-temperature medium-dust SCR ultra-low emission project

in Shandong Province. Spraying dust is only the tip of the iceberg of green environmental protection measures, and technology empowerment is the magic weapon to build a green factory. Donghua Science and Technology has built the first medium-temperature medium-dust SCR ultra-low emission project in Shandong Province, with an annual emission reduction of about 200 tons of nitrogen oxides and 15 tons of ammonia escape, which has pioneered the ultra-low emission of pollutants in the region.

▲ Donghua Science and Technology Intelligent Environmental Protection Integrated Management Platform

In addition, Donghua Science and Technology has also built an intelligent environmental protection integrated management and control platform based on the cement "industrial brain" 2.0, realizing intelligent, automated and precise management and control. The quality stability of process carbon control and end carbon elimination has been improved by 28.48%, and the comprehensive energy consumption of clinker line has been reduced by 6.73%, which promotes the transformation of "green intelligent manufacturing" of enterprises. In the first State-owned Enterprise Digital Scene Innovation Professional Competition of SASASAC of the State Council, the project of "Fine Energy Management and Control in the Production and Manufacturing Links of Cement Industry" won the second prize.

▲ "Ammonia to hydrogen" project can realize the replacement of coal

by hydrogen and ammonia fuel. With the deepening of the national "double carbon" strategy, in recent years, Donghua Science and Technology Company has also focused on the research of clean energy and new materials such as wind and solar energy storage, ammonia to hydrogen, etc.

Donghua Science and Technology joined hands with Xiamen University to build the world's first demonstration project of replacing coal with ammonia for hydrogen supply in the cement industry, which was successfully industrialized and put into operation in June 2022, and achieved 6% coal substitution in the first phase of operation. It has successfully entered the list of the first batch of major scientific and technological research projects in the national building materials industry.

▲ The green mine

being developed and constructed by Donghua Science and Technology Donghua Science and Technology also relies on high-quality limestone mineral resources reserves to accelerate the development of calcium-based new materials industry, promote the transformation and upgrading of traditional industries, and has obtained two certifications of China's environmental label and low-carbon products.
