Linfen County, Shandong Province, chemical fertilizer companies through the development of scientific and technological innovation, the implementation of energy-saving measures and other means, and constantly optimize the production process, promote technological advances in equipment, energy-saving work to achieve remarkable results. In the notice issued by the National Development and Reform Commission on the 2010 implementation plan for the financial incentives for energy-saving technological transformation projects (the first batch), there are 7 projects in the county, all of which are chemical projects, of which 5 are chemical fertilizer projects. . The total investment of the seven projects is 356 million yuan, and the annual energy saving can reach 167,000 tons of standard coal, which has won a total of 33.46 million yuan in state financial incentives.
Fertilizer industry is a large energy consumer, implementing energy-saving and emission reduction is not only the internal needs of enterprises to change the mode of economic growth, but also an inevitable choice for enterprises to achieve sustainable development. Linfen County's chemical fertilizer enterprises actively adopt new energy-saving technologies and new equipment in accordance with the requirements of “energy saving, consumption reduction, pollution reduction, and efficiency enhancement†and invest heavily in the production of complex fertilizer production equipment and processes with high energy consumption and serious pollution. Timely transformation, so that energy-saving emission reduction work in the same industry in the country. Shandong Ruibang Chemical Fertilizer Co., Ltd. utilizes the original tower of high-tower melt granulation compounded by the steam drum granulator. The production process adopts mechanized elevator feeding, the tower top steam melts urea, and the top material is mixed. The entire production process is All DCS automation control, no coal, no water, no dust, no emissions, not only save energy, but also reduce the air pollution of SO2 gas. Compared with the traditional compound fertilizer production process, each ton of compound fertilizer produced can save 45 kg of standard coal and save 17 kwh of electricity. The 6 fertilizer companies in the county have newly set up 8 sets of tower-type melt granulation compound fertilizer production equipment with an annual production scale of over 3 million tons. This alone can save 135,000 tons of standard coal and save 51 million kwh of electricity each year. Shandong Fuji Fertilizer Co., Ltd. changed the production process of the original compound fertilizer device to the granule granulation process to produce compound fertilizer, which not only saved a large amount of technical reform funds, but also effectively increased the production capacity and product quality of the device. With this method, the nutrient concentration of the ternary compound fertilizer can reach 54%, and the water solubility rate of the product P2O5 is more than 80%. The process adapts to a wide range of operation, stable product quality and high pass rate, can effectively solve the problem of fertilizer agglomeration, and make the compound fertilizer product from a physical synthesis to a chemical synthesis. The smoothness and appearance color of the fertilizer granules are better than that of the conventional granule granulation method. Big improvement. Compared with the original process, the production process can save 43 kilograms of standard coal for each ton of compound fertilizer, and the economic and social benefits are very significant.
The controlled-release fertilizer developed by the county's Kim Jongda Group can supply nutrients according to the needs of crop growth, and is called “fertilizer with switch†by farmers. It is referred to in the industry as “new type green energy fertilizer for the 21st centuryâ€. The nitrogen utilization rate of the fertilizer can be increased by more than 50%, and the usage of the fertilizer can be reduced by 1/3 or 1/2. The crop can still increase the production and increase income. Without increasing the input of fertilizer, it can save the top-dressing laborer and solve the common chemical fertilizer belt. Serious land pollution problems. What is even more commendable is that by cracking the world's technical problems of high production costs, this “noble†fertilizer that can only be used for flowers and lawns in countries such as the United States, Japan, and Germany has gradually entered the land of the Chinese people.
