Research And Practice Of CDQ Equipment Installation Technology

CDQ is an energy-saving, environmental protection and improving the quality of coke quenching techniques. It belongs to the important promotion technology in the state coking industry. In the next few years, the construction of CDQ projects will be in a peak period.According to the domestic CDQ projects character: high quality requirements, short construction period, low-cost, domestic technology and equipment, as well as construction technology and technical measures improperly so that the accuracy cannot arrive to the requirement, thus affecting the operation of production. How to ensure high-quality, low-cost, short-period of the completion of CDQ equipment installation projects, successful and stable operation of production, the paper on this subject was studied:(1) Through instruction and analysis of the CDQ process, engineering plane, facade of the system layout and its major equipment components and functions, summarize the characteristics and difficulties of CDQ projects.(2) According to the components and characteristics of the CDQ equipment, study out installation technology of the CDQ equipment - steel structure of coke quenching chamber, coke quenching chamber, charging device, discharge device, gas circulation system, boiler and the commissioning construction technology.(3) According to the focus and difficult of the accuracy and the quality control during the CDQ equipment installation, study out the critical construction technology of the CDQ equipment: steel structure of coke quenching chamber installation, coke quenching chamber production and installation, the main part of CDQ, gas circulation system and boiler concrete foundation settlement is not synchronous processing technology measures as well as CDQ system dynamic gas-tight test.The construction technology and critical construction technology studied out in this paper are used in project practice, it will guide CDQ equipment installation projects and ensure that the installation accuracy, improve construction quality, economical construction period, lower construction cost and guarantee of safety with good results, so that CDQ equipment successful operation, into production and stable operation, achieving better economic and social benefits. This research production has guiding value for enterprise of construct CDQ equipment installation projects.
