Abstract: This article introduces the design of 2500L glass-lined open reactor. The main ingredient of glass is SiO2. Its corrosion resistance is superior to stainless steel as it can resist strong acids, alkalis, organic acids and other corrosive media. Lining the high-silica glass to the inner surface of the steel container make it become composite products with dual advantages. Because of its chemical stability as glass and excellent mechanical properties similar to metal, it will take place of stainless steel, nonferrous metals, plastics and other materials in many ways. According to process parameters and the basics like GB150-2011<Pressure Vessel>, GB25025-2010<Honing Glass Equipment Technical Conditions>, HG/T2371-2003<Open Honing Glass Stirred Vessel>, <Chemical Process Manual>, TSG R0004-2009<Fixed Pressure Vessel Safety Technology and Inspection Procedures>, we should determine the design parameters.  Then do structural design, process calculation and verification of head, cylinder, Flanges, jacket, shaft, bearings. At last put forward the requirements of manufacture, inspection and acceptance. Final design includes three CAD maps, a general plan manual and a design instruction.
