摘　　要：以上海市白龙港污泥处理处置二期工程为例,介绍了鼓泡流化床焚烧炉内衬材料的设计情况,给出了喷涂料施工程序,总结了施工过程的质量控制技术要点,并对烘炉后焚烧炉耐材施工质量效果进行了验证。喷涂料施工前,通过试喷确定施工工艺参数,通过绘制喷涂区块排版图来指导现场施工,在控制每区块厚度和喷涂质量的同时使整体喷涂质量达到标准。在喷涂施工过程中,根据试喷工艺参数控制好加水量、气压、喷枪角度等确保喷涂质量。完成焚烧炉耐材施工全部工作后,在烘炉阶段,根据实际施工环境、材料加水量,理论烘炉温升曲线0~125℃温升阶段,由5 h调整控制在8 h,放缓温升速度,避免温升过快导致水分排除不畅,减少裂纹产生。该工程焚烧炉内衬耐火喷涂料施工质量达到了控制标准要求。Taking the phaseⅡsludge treatment and disposal project in Shanghai Bailonggang as an example,the design of lining materials for bubbling fluidized bed incinerator is introduced,the spray coating construction procedure is provided,the quality control technical points in the construction process are summarized,and the construction quality effect of refractory materials for incinerator after drying is verified.Before spraying,the construction parameters are determined by trial spraying,and the layout of spraying blocks is drawn to guide the field construction,thus the overall spraying quality can reach the standard while controlling thickness and spraying quality of each block.During the spraying process,the spraying quality is guaranteed by controlling the amount of water,air pressure and spray gun angle according to the trial spraying process parameters.In the drying stage after completing all the refractory material construction work of incinerator,the 0-125℃rise stage in the theoretical temperature rise curve is adjusted from 5 to 8 h,according to the actual construction environment and material water addition,so as to slow down the temperature rise speed,avoid poor water drainage and reduce cracks due to too fast temperature rise.The construction quality of fire-resistant spray coating for the incinerator lining of the project has reached the requirements of control standard.
