Overcoming the world's difficult problems and realizing the industrialization of gypsum-based acid production technology
Gypsum-based acid production with co-production of cement is the world's cutting-edge technology. After 2 years of research, Lubei has filled the domestic gap and become the first gypsum-based acid production company in China. However, the instability of its core technology, raw meal preparation and control of returning to special kiln, restricts the industrialization of scientific and technological achievements. Feng Jiutian is not afraid of books and difficulties, exploring the best ratio of raw materials, and successfully developing new technologies such as microcomputer batching and rotary kiln automatic control, so that the gypsum acid-making technology has been industrialized, setting a world record of 384 days of continuous safe operation of rotary kiln, and expanding the capacity of the national green chemical PSC demonstration device of "3, tons of ammonium phosphate with 4, tons of sulfuric acid and 6, tons of cement" to "six, eight and twelve", with an annual increase of 24.5 million yuan. It has solved the worldwide problem that phosphogypsum, a by-product waste residue of ammonium phosphate, occupies an area that pollutes the environment. The economic, social and environmental benefits are organically unified, and it has become a model of China's green chemical industry, and has been included in the "Ninth Five-Year Plan" major scientific and technological achievements promotion plan by the State Science and Technology Commission. Scientists at Xiangshan Science Conference evaluated zero emission technology, green environment technology and sustainable development technology.
Dare to be the first to make a breakthrough in the technology of gypsum out-of-kiln decomposition
Feng Jiutian undertook the research on the new technology of gypsum out-of-kiln decomposition, and presided over the design and construction of a pilot plant. Burned by high-temperature materials in the test, still not leaving the test bench. After thousands of experiments, he solved hundreds of difficult problems, got through the process in 1995 and made a major breakthrough. This technology can reduce the energy consumption of the system by 3% and increase the annual benefit by 19 million yuan, which is an international initiative, and the decomposition process and device outside the kiln won the national invention patent.
comprehensively develop marine resources and create a green industrial chain
Feng Jiutian designed and created a "multi-purpose" model of marine aquaculture, bromine extraction, salt production and saline-alkali co-production, linking marine aquaculture, bioengineering and saline-alkali industry to create a green industrial chain, so that in 1993, a million-ton saltworks, a 5,-ton bromine factory and a 5,-mu farm were built, achieving a comprehensive benefit of 3 million yuan. In the autumn of 1994, the worst tidal wave occurred in a hundred years. In order to rescue the dam, he was the first to jump into the tide and led hundreds of rescue workers to weave a human wall.
Committed to the promotion of achievements
Committed to the promotion of achievements, making the technology of gypsum-based acid production go to the whole country and the world. Feng Jiutian actively devoted himself to the transfer of gypsum-based acid production achievements, visited and distributed in 14 provinces and cities, and put them into practice in 1 countries, which can create more than 7 billion yuan of comprehensive benefits for the country every year. He has led a delegation to study abroad for six times, signed technology transfer agreements with Russia, Belarus and other five countries, and is now in the process of acquiring Kazakh Phosphorus Industry Group with total assets of 1 billion US dollars.
working hard to create a green industrial base
In order to provide a large-scale domestic device for comprehensive utilization of phosphogypsum, promote the sustainable development of China's phosphate compound fertilizer industry, promote the localization process of China's ion-exchange membrane caustic soda technology, and create the largest production base of phosphate compound fertilizer, gypsum acid production, marine chemical industry and chlor-alkali in China, he designed and presided over five national key green chemical PSC amplification projects and ion-exchange membrane caustic soda with a total investment of nearly 2 billion yuan. In October 1996, the project started construction, and he gave up his family and cared for everyone, fighting day and night on the construction site. Enriching itself has deepened the connotation of the entrepreneurial spirit of "hard struggle and pursuit of Excellence" in Lubei.
