Design of continuous supercritical fluid dyeing device
Abstract:The continuous supercritical fiuid dyeing device which containers for high pressure dyeing tube ,flange,carrier of gauze,closing device and their accessories.Because the pressure in the high pressure dyeing tube is 42MPa and the temperature is 140℃，316 stainless steel was chosen as material of the high pressure dyeing tube and flange.And I must design flange by use the method of Waters.Before do the design of dyeing device, the first step is feasibility analysis, and then according to the given process parameters and conditions of the device. Then design the dyeing device . In order to ensure the structure strength and performance, strength, stiffness and stability must be checked. After checking, O-rings,protector of O-rings,bezel and flanges, gaskets, fasteners were determined. Finally, we could consider the overall , simulation and optimization. Above all, the design of the continuous supercritical fluid dyeing device will be completed basically.
Key Words: supercritical carbon dioxide；continuous feeding；high-pressure technology；strength check
