摘要
Abstract
Hydraulic decoking three-way valve is the key equipment for a refinery delayed coking unit. Based on the structure of the Hydraulic decoking three-way valve, which designed by Hefei General Machinery Research Institute, the Internal flow channel model of bypass circulation and hydraulic decoking conditions were built. By using the SIMPLE algorithm and Standard k - e turbulence model, CFD analysis of internal flow field of three-way valve and a comparison with the original calculation were carried out. The simulation results show that: the valve in the bypass circulation condition can dissipate energy step by step, and meet the pump& minimum flow requirements; In full-flow hydraulic decoking condition, the pressure drop through three-way valve only accounts for 0. 6% of system pressure drop, and the design of orifice under the sealing surface protects the main sealing surface not to be destroyed effectively. The numerical simulation results of the valve internal flow field comply to the field application.关键词
