<p><P>PROBLEM TO BE SOLVED: To provide a pressure vessel which can improve working properties during assembly or maintenance and a separation membrane module having the pressure vessel. <P>SOLUTION: An engagement part (a recess 42) engaging with a separation membrane element 10 inserted from an insertion port 43 is formed at one end of the pressure vessel 40. At both ends of the pressure vessel 40, connection parts 41 which can connect another pressure vessel 40 in series are formed. As a result, after the separation membrane element 10 is inserted from the insertion port 43 into the pressure vessel 40 and engaged with the connection part (the recess 42), only by connecting the pressure vessel 40 with the other pressure vessel 40 in series through the connection parts 41, the separation membrane module 1 can easily be formed. Even when the separation membrane element 10 is exchanged, only by carrying out work to the pressure vessel 40 in which the separation membrane element 10 to be exchanged is held, the separation membrane element 10 can easily be exchanged. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
