Design of Washing Tower
Abstract：Tower equipment is chemical, petrochemical and refining, pharmaceutical, environmental protection, and other industrial department is a kind of important unit operation, The design of the tower equipment consists of problem to solve, in addition to determine the details of the tower equipment structure outside, more important is to do all kinds of work check, in order to ensure that the design of tower equipment can not only finish the normal operation, and must comply with the national safety production standards. Check the content mainly includes: quality load, earthquake loads, the wind loading, etc, also including the strength and stability are checked. Drawings including a assembly drawing and drawing. Complete body of complete set of equipment of the column plate structure design, structure design is the design of pressure vessels parts, namely calculation of the tower wall thickness, the head of the structure and size, design of the column accessories, and took over the design. Auxiliary equipment and accessories structure design: take over the design and the related flange of selecting, except the foaming machine, manhole and its annex design. The tower check: including tower body and the head of the thickness is sure, tower equipment quality load and natural vibration period of calculation, earthquake loads and seismic moment, the wind load and the wind bending moment calculation, cylinder axial stress and cylinder stability checking, tower pressure test equipment of stress and axial stress of skirt a check.
Key words: sieve-tray column; structure design; screen panel tower；Plate properties.
