Tsinghua University, etc., resource flue gas desulfurization technology developed
from “15″ 863 Program to support the energy sector, Tsinghua University and Tsinghua Tongfang, China Agricultural University, State Power Environmental Protection Research Institute of shared responsibility “may resource flue gas desulphurization technology” has recently passed the acceptance issue. May be resource issues around the goal of flue gas desulphurization, research and development with China’s own intellectual property rights that can be resource sets of slurry jet flue gas desulfurization technology, and applied to practical engineering construction, produced good social and economic benefits.
For many years, the existing large-scale coal-fired power plant flue gas desulphurization technology is mostly dependent on foreign companies not only have to pay high royalties, and the key components are to be imported, developed with independent intellectual property rights so fume desulfurization technology imminent.
“15″ period, in the 863 Program with the support of Tsinghua Tongfang and Huaneng Power International AG signed a contract to slurry jet flue gas desulphurization technology into the sea of Huaneng Power Plant Unit 8 # 1 × 330MW gas desulfurization of the actual projects. So that the flue gas desulphurization system processing reached 1152000Nm3 / h, SO2 content of 2050 mg/Nm3. 2006 Nian 6 Yue The system is put into commercial operation. Running results show that slurry jet flue gas desulfurization technology to effectively prevent the operation of the desulfurization system, scaling and plugging problems, significantly reduce the system running resistance, the system is running stable, safe and reliable investment and low operation cost, high efficiency desulfurization , to changes in boiler load adaptability and so on. By the Hainan Provincial Environmental Monitoring Center for testing, the demonstration project for more than 96% desulfurization efficiency, flue gas sulfur dioxide emission concentration comply with national standards and fully meet the design requirements.
to resolve the flue gas desulfurization by-products of resource utilization, the research group plot experiments and demonstrations through the method of combining the initial proposed improvement of desulfurization by-products of different degree of salinity of soil fertilizer, farming, cultivation and management method, and in Inner Mongolia Wulateqianqi woods on saline-alkali wasteland 3 hectares, built a field experiment demonstration area, demonstration areas were sunflower germination rate reached 80%, sunflower growing well, now has reached 200 per mu kg. Not only achieved the improvement of saline soil, but also realized the rational use of desulfurization waste.
successful completion of this subject, not only indicates that China has large coal-fired power plant flue gas desulphurization technology, the situation of long-term reliance on foreign imports have been broken, and further consolidated the slurry jet FGD flue gas desulfurization technology in the industrialization process in the field of leadership, and promote a large-scale coal-fired power plant flue gas desulfurization process of localization achieved desulfurization by-product of resource utilization.
清华大学等资源的烟气脱硫技术开发
从“十五”863计划，以支持能源部门，清华大学和清华同方，中国农业大学，国家电力环境保护研究所共同责任“的可能资源的烟气脱硫技术”近日通过验收的问题。可能是周围的烟气脱硫，研究和中国的自主知识产权，可在液柱喷射烟气脱硫技术发展的目标，集资源资源问题，并应用于实际工程建设，产生了良好的社会效益和经济效益。
多年来，现有的大型燃煤电厂烟气脱硫技术主要是依赖于外国公司不仅要支付高额专利费，以及关键部件是进口的，具有自主知识产权的开发权利，烟气脱硫技术迫在眉睫。
“十五”期间，签署了与清华同方和华能国际电力股份公司的支持863计划一项合同，液柱喷射烟气脱硫技术进入华能电厂8号机组＃1 ×型330MW烟气脱硫海实际的项目。从而使烟气脱硫系统处理达到1152000Nm3 /小时，2050年mg/Nm3二氧化硫含量。 2006念6岳该系统投入商业运营。运行结果表明，液柱喷射烟气脱硫技术，有效地防止了脱硫系统的运作，缩放和堵塞问题，大大降低了系统运行阻力，系统运行稳定，安全和可靠的投资和运行费用低，效率高，脱硫，在锅炉负荷变化的适应性等。由海南省环境监测中心测试，对超过96％，脱硫效率示范项目，烟气二氧化硫排放浓度符合国家标准，完全符合设计要求。
解决了烟气脱硫的资源利用的产品，情节研究小组通过试验，示范相结合的初步建议的改善脱硫的方法对土壤化肥，农业，种植不同程度的盐碱化产品和管理方法，并在内蒙古乌拉特前旗树林的盐碱盐碱荒地3公顷，建立了田间试验示范区，示范区的向日葵种子发芽率达80％，向日葵长势良好，现在已达到每亩200公斤。不仅实现了盐碱土壤改良，而且还实现了脱硫废弃物的合理使用。
成功完成这一问题，不仅表明中国拥有大型燃煤电厂烟气脱硫技术，长远的长期依赖国外进口的局面被打破，并进一步巩固了液柱喷射烟气脱硫脱硫技术在领导领域的产业化进程，促进大型燃煤电厂烟气脱硫的实现本地化脱硫过程的资源利用产品。06.9.29
