摘要:- 以上海市白龍港污泥處理處置二期工程為例，介紹了鼓泡流化床焚燒爐內(nèi)襯材料的設計情況，給出了噴涂料施工程序，總結(jié)了施工過程的質(zhì)量控制技術(shù)要點，并對烘爐后焚燒爐耐材施工質(zhì)量效果進行了驗證。噴涂料施工前，通過試噴確定施工工藝參數(shù)，通過繪制噴涂區(qū)塊排版圖來指導現(xiàn)場施工，在控制每區(qū)塊厚度和噴涂質(zhì)量的同時使整體噴涂質(zhì)量達到標準。在噴涂施工過程中，根據(jù)試噴工藝參數(shù)控制好加水量、氣壓、噴槍角度等確保噴涂質(zhì)量。完成焚燒爐耐材施工全部工作后，在烘爐階段，根據(jù)實際施工環(huán)境、材料加水量，理論烘爐溫升曲線0~125 ℃溫升階段，由5 h調(diào)整控制在8 h，放緩溫升速度，避免溫升過快導致水分排除不暢，減少裂紋產(chǎn)生。該工程焚燒爐內(nèi)襯耐火噴涂料施工質(zhì)量達到了控制標準要求。
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.
