Hefei cement research and Design Institute Co., Ltd. (referred to as "Hefei Institute") has always been a research institute and has more than 60 years of research and development history of cement technology. Many new technologies in the cement industry come from Hefei Institute. For decades, the Hefei Institute has been insisting on serving the technological progress of the cement industry, aiming at the advanced level at home and abroad, focusing on the research and development of the new process and equipment for energy saving, environmental protection and automation technology in the cement production process, and has established a complete R & D system, thus forming the optimization of water mud thermal engineering, powder engineering, cement industry automation, environmental protection engineering and cement raw materials. Mining and comprehensive utilization of resources are the dominant specialties.
The Hefei Institute has established a complete R & D system. Since the establishment of the hospital, It has undertaken over 500 research projects including national science and technology tackling key projects and departmental key projects. More than 300 scientific and technological achievements have been identified, most of which are in the leading international level, and some projects have filled the gap in China. More than 600 patents have been applied, and a number of patents have been authorized by international multi nations. Many times have been awarded the national science and technology progress award, among which 6 have been awarded the two prize of national science and technology progress; more than 10 technical achievements have been included in the national promotion plan for major scientific and technological achievements; they have presided over or participated in the formulation of 10 important standards for cement and related industries. It has made important contributions to the scientific and technological progress of the cement industry. Since the 80s of last century, with the introduction of the new dry process cement production line, the Hefei Institute has been involved in many science and technology projects in the five year plan since the "65". Based on the introduction of key technologies, it has researched and developed the grinding technology and installation, pre decomposing system, metering system, distributed automatic control system, dust collector, conveying system and so on. A series of core technologies have produced a large number of important scientific and technological achievements: "key technologies and equipment for high energy efficiency clinker firing", "HRM vertical mill", "HFCG roller press", "steel belt conveyor hoist", "high-precision and high-yield grinding", "Coriolis force flowmeter", "integrated quantitative feed system", "rotor powder quantitative feeding system", "high concentration low" Fast pulse pneumatic conveying device "," 5000t/d " The development and application of bag dust remover for precalciner kiln, "low resistance bag filter", "high-efficiency electrostatic precipitator", "denitrification and denitrification technology", "cement kiln co processing technology", "integrated technology of positive and negative pressure pneumatic conveying system", "intelligent production technology of cement production line", "intelligent mining of cement raw material mining and ecological restoration technology of mining area". These achievements have made great contributions to the technological progress of China's cement industry.
The Hefei Institute has built an experimental base of 5280 square meters of R & D center, including vertical mill test room, extrusion grinding laboratory, ultrafine classification laboratory, metrology and quantitative feeding system laboratory, R & D center garbage, sludge, solid waste laboratory, general equipment laboratory, environmental protection company laboratory, Thermal Engineering Center Laboratory, energy saving powder material vertical transportation and metering. The lab, which covers all aspects of the cement industry, aims to build a leading international advanced research and development base for cement industry in Hefei, and provide technical support for the sustainable development of the Institute.
In recent years, the Hefei academy has been saving. Energy, The basic national policy of resources and environmental protection is guided by the development and expansion of research projects around the theme of energy conservation, emission reduction, environmental protection and comprehensive utilization, and the carbide slag has been completed. comprehensive utilization The scientific research work of several comprehensive utilization projects such as low temperature waste heat power generation and garbage incineration has increased the utilization efficiency of resources and energy, won the recognition of the majority of users, and reached the leading level in the same industry.
