項目背景分析

中海石油天野化工( 集團) 有限責任公司現(xiàn)有1 套年產(chǎn) 300kt 合成氨、 520kt 尿素生產(chǎn)裝置, 1 套年產(chǎn)200kt 甲醇生產(chǎn)裝置。其中, 尿素裝置尿素溶液從造粒塔冷卻后形成的尿素顆粒經(jīng)皮帶系統(tǒng)輸送到散料庫, 再經(jīng)皮帶系統(tǒng)輸送到包裝樓進行包裝, 通過輸送皮帶送往站臺裝車。

原有的皮帶控制系統(tǒng)電路都是相當復(fù)雜的老式繼電回路, 加上運行時間已達十多年, 故障發(fā)生率很高, 一旦發(fā)生故障需用很長時間來查找和排除故障點, 給檢修和維護帶來很大不便。

隨著 PLC 在工業(yè)控制中的應(yīng)用越來越廣泛,PLC 技術(shù)也越來越成熟, 現(xiàn)已將原有的控制電路改造成由 PLC可編程控制的電路, 來改變目前輸送系統(tǒng)存在的問題。
