攪拌反應釜夾套類型的選擇

來源: 時間:2012-11-22 14:20:38 瀏覽次數:

夾套類型有整體夾套、半圓管夾套、型鋼夾套和蜂窩夾套。通常整體夾套的壓力不能超過1MP ,否則將會因罐體及夾套壁厚太大,增加制造的困難。當反應器直徑較大或采用的傳熱介質壓力較高時,可采用后三種類型

夾套類型有整體夾套、半圓管夾套、型鋼夾套和蜂窩夾套。通常整體夾套的壓力不能超過1MP  ,否則將會因罐體及夾套壁厚太大,增加制造的困難。當反應器直徑較大或采用的傳熱介質壓力較高時,可采用后三種類型,這樣不但能提高傳熱介質的流速,改善傳熱效果,而且能提高筒體承受內、外壓的強度和剛度,各種夾套的使用范圍見下表:
