脱硫塔施工过程中对质量监控应注意的8个问题
1、对设备、材料及零部件、构件的到场应及时督促做好开箱验收和材料、设备的申报核验工作,从而防止不合格材料或设备被用于工程中。
1. The presence of equipment, materials, spare parts and components should promptly supervise the acceptance of open boxes and the declaration and verification of materials and equipment, so as to prevent unqualified materials or equipment from being used in engineering.
2、特别注意对设备基础施工过程质量的监控和验收。
2. Pay special attention to the quality control and acceptance of equipment foundation construction process.
3、对引风机组的安装、组对质量的监控是为保证风机正常工作,达到设计所要求各项技术指标,满足对除尘器进出风量及风压。
3. Installation and quality monitoring of induced draft fan units are to ensure the normal operation of the fans, meet the technical requirements of the design, and meet the air flow and pressure of the dust collector.
4、对烟道风管安装的检查监控,能提高吸排风效率,降低能耗。
4. Inspection and monitoring of flue duct installation can improve suction and exhaust efficiency and reduce energy consumption.
5、对除尘器本体及内构件和执行机构安装的检查监控是保证布袋式除尘器能否正常有效运作的关键,锅炉除尘器也是整个系统的处理器,因此它的安装质量直接影响了改造工程的质量,是整个工程的重中之重。
5. Inspection and monitoring of the installation of the dust collector body and its internal components and executing mechanism is the key to ensure the normal and effective operation of the bag-type dust collector. The boiler dust collector is also the processor of the whole system. Therefore, its installation quality directly affects the quality of the renovation project and is the most important part of the whole project.
6、对保温绝热工程的检查监控是降低能耗,提高生产效率的一种有效措施。
6. Inspection and monitoring of thermal insulation project is an effective measure to reduce energy consumption and improve production efficiency.
7、电仪单体调试、机构单体调试、风机机组单机试车以及联动试车的检查监控是对布袋式除尘器改造安装工程终质量的检验,因此要旁站监控,发现问题,做好记录,并及时有效地督促有关单位落实整改,确保终调试合格。
7. Inspection and monitoring of electrical instrument monomer debugging, mechanism monomer debugging, fan unit mono-engine test running and linkage test running are the inspection of the final quality of bag filter retrofitting and installation project. Therefore, it is necessary to bypass station monitoring, find problems, make good records, and promptly and effectively urge relevant units to carry out rectification and improvement to ensure that final debugging is qualified.
8、在生产试运行过程中,注意对工程质量问题的观察,注意对引风机组运行质量及指标的观察,注意对除尘器漏风率、排放浓度等性能指标的检测等,督促保运单位及时的处理有关工程质量问题,终使系统运行正常。
8. In the process of trial operation, attention should be paid to the observation of engineering quality problems, to the observation of operation quality and indexes of induced draft fan units, to the detection of performance indexes such as air leakage rate and emission concentration of dust collectors, and to urge the transportation units to deal with the related engineering quality problems in a timely manner so as to ensure the normal operation of the system.
