桅杆在拆除沉降槽吊装中的应用

Application of Mast in Demolition of Sedimentation Trough

在氧化铝拆除搬迁中,沉降槽是氧化铝拜耳法工艺中的重要组成部分,也是氧化铝的关键设备。而本拆除工程是沉降槽系统分部工程,是危险性较大的拆除工程。该部分主要有7台单体槽子构成的沉降系统和地面管道支架系统。工程特点属部分保护性拆除工程,要求沉降系统中的搅拌装置、桁架、槽壁板、支座辐射梁、内外立柱、中心筒以及管道支架系统做保护性拆除,拆除完好率分别80%和85%。

In the removal and removal of alumina, the settling tank is an important part of the alumina Bayer process and the key equipment of alumina. And the demolition of the project is the settlement tank system division project, is a more dangerous demolition project. This section consists of seven units of troughs consisting of subsidence systems and ground pipe support systems. The engineering features are part of the protective removal project, requiring the settlement system of the mixing device, truss, slot wall, bearing radiation beam, inside and outside the column, the central tube and pipe support system to do the protective removal, removal rate of 80% and 85 %.
