Abstract: | As a core equipment of the important chemical material ( butanol and octanol ) production unit , the butyraldehyde converter has been relying on import for quite a long time .The process principle ,basic parameters and design condition are presented for the large -scale butyraldehyde converter of a certain chemical company ,and its structure characteristics are also pointed out .As to the key design technology , such contents as the temperature field analysis ,flexible tube -sheet structure,technical requirements of large-diameter thin-wall heat exchanger tube ,design of tube to tube-sheet joint ,weldment structure of forging ring-tube sheet -cylinder and bracing structure of tube side etc .are discussed .As to the key manufacturing technology ,such contents as the anti -deformation technology of tube -sheet,process of tube hole ,quality control of tube to tube -sheet joint , accuracy control of tube bundle supporting grid , NDE inspection of forging ring etc .are discussed.Heretofore,nine butyraldehyde converters have been in-dependently designed by Hefei General Machinery Research Institute ,manufactured by China First Heavy Industries and successfully applied in the butanol and octanol unit , indicating the whole set of domestic development technology was mastered for such equipment in China . |
