硝酸還原塔塔體高度29.8米,直徑3.8米,吊裝總重量96噸,是合成草酸二甲酯的關(guān)鍵設(shè)備之一。此設(shè)備采用了宇部興產(chǎn)株式會社最新的硝酸還原技術(shù),能顯著降低甲醇水溶液中的硝酸含量以及后續(xù)系統(tǒng)中的堿耗量和廢水量,系首次應(yīng)用在東華科技的總承包項目中。東華科技在硝酸還原塔的制造過程中對制造商的質(zhì)量行為和實體質(zhì)量進(jìn)行了嚴(yán)格控制,定期對生產(chǎn)計劃的執(zhí)行情況進(jìn)行檢查,確保該設(shè)備準(zhǔn)時到場并順利通過了現(xiàn)場聯(lián)合驗收。
此次吊裝選用450T履帶吊主吊,200T履帶吊溜尾,采用雙吊車抬送法吊裝就位。設(shè)備臥式運輸至現(xiàn)場指定位置時,主吊耳靠近主吊車并水平對稱放置,溜尾吊耳靠近溜尾吊車并位于正上方。450T履帶吊掛超起配重將設(shè)備從頂部提起,200T履帶吊隨設(shè)備直立而前行,設(shè)備直立后200T履帶吊松鉤。450T履帶吊將設(shè)備提升至17米高,調(diào)整位置后穿過結(jié)構(gòu)平臺預(yù)留孔,將設(shè)備緩慢放下并就位。
吊裝開始前,東華科技組織施工分包商的安全、技術(shù)、質(zhì)量管理人員依次對現(xiàn)場施工人員進(jìn)行了交底,監(jiān)督施工分包商嚴(yán)格按照已審批的吊裝專項方案進(jìn)行作業(yè),保證了整個吊裝過程的安全和質(zhì)量。
此次吊裝作業(yè)的順利實施,是對所有參建人員辛勤付出的最好回報,得到了項目業(yè)主的充分認(rèn)可,東華科技山西美錦華盛乙二醇項目部將再接再厲,按計劃完成另外兩臺硝酸還原塔的吊裝任務(wù),為項目安裝工作打開新局面。
