The desulfurization tower used as tower packing tower, packed tower of the basic features of simple structure, drop down a small, mass transfer efficiency, ease of use of corrosion-resistant materials and so o .The basic structure of the internal demister, liquid distributors, liquid re-distributor, the vortex nozzle, bearing plates and filler plate. The desulfurization tower in the design process of reference GB150-1998 steel pressure vessel, chemical containers and equipment Concise Design Manual, JBT4710-2005 steel tower container and other standards.The desulfurization tower design includes the selection of tower parts, design, design calculations, etc., in the process, through the information search, data calculation and a series of methods to integrate information and data required for the design.The teachers constantly pointing with their constantly revised and improved, culminating in this design.
