  摘要:

  以上海市白龙港污泥处置措置二期项目为例，引见了鼓泡流化床燃烧炉内衬材料的设想环境，给出了喷涂料施项目序，总结了施工进程的质量节制手艺要点，并对烘炉后燃烧炉耐材施工质量结果进行了验证。喷涂料施工前，经由过程试喷肯定施工工艺参数，经由过程绘制喷涂区块排邦畿来指点现场施工，在节制每区块厚度和喷涂质量的同时使全体喷涂质量到达尺度。在喷涂施工进程中，按照试喷工艺参数节制好加水量、气压、喷枪角度等确保喷涂质量。完成燃烧炉耐材施工全数工作后，在烘炉阶段，按照现实施工情况、材料加水量，理论烘炉温升曲线0~125 ℃温升阶段，由5 h调剂节制在8 h，放缓温升速度，避免温升过快致使水份解除不顺畅，削减裂纹发生。该项目燃烧炉内衬耐火喷涂料施工质量到达了节制尺度要求。

  Abstract:

  Taking the phase Ⅱ sludge 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.
