Abstract
The cylindrical body of a pressure vessel for use as a reaction vessel, is built up from courses of flat circularly arcuate segmental plates, the courses being located with respect to each other by locating means passing through aligning openings in the plates. To facilitate construction the openings in each plate are disposed in a symmetrical pattern or array. The locating means may be pins or preferably sleeves, and prestressing means for holding the courses together may be provided by tie-rods or cables passing through such sleeves and also possibly through openings not taken up by locating means. The floor and/or cover of the pressure vessel may be double-walled, and prestressing means provided within the double walls for tightly securing the floor and/or cover to the inside of the cylindrical wall.
Claims5
A pressure vessel comprising:
- a cylindrical wall formed of courses of a plurality of flat circularly arcuate segmental plates each plate being axially traversed by a plurality of openings disposed in a symmetrical pattern or array at least some of the holes in adjacent courses being in alignment, and wherein the ends of the plates in each course overlap the ends of the plates in an adjacent course, and wherein locating sleeves are inserted in said aligned openings, and through each of the said locating sleeves prestressing means selected from a tensioning cable and a tie rod is extended and is secured at the top and the bottom of said wall;
- a double-walled floor extending across said cylindrical wall inserted in a said course adjacent the bottom, said double-walled floor containing a prestressing element radially extending from a said wall plate to securing means in said floor and adjustable tensioning means for adjusting the tension in said prestressing element;
- and a double-walled cover extending across said cylindrical wall adjacent said top.
A pressure vessel comprising:
- a cylindrical wall formed of courses of a plurality of flat circularly arcuate segmental plates each plate being axially traversed by a plurality of openings disposed in a symmetrical pattern or array at least some of the holes in adjacent courses being in alignment, and wherein the ends of the plates in each course overlap the ends of the plates in an adjacent course, and wherein locating sleeves are inserted in said aligned openings, and through each of the said locating sleeves prestressing means selected from a tensioning cable and a tie rod is extended and is secured at the top and the bottom of said wall;
- a double-walled floor extending across said cylindrical wall inserted in a said course adjacent the bottom;
- and a double-walled cover extending across said cylindrical wall adjacent said top, said double-walled cover containing a prestressing element radially extending from a said wall plate to a securing means in said cover, and adjustable tensioning means for adjusting the tension in said prestressing element.

- a double-walled floor extending across said cylindrical wall inserted in a said course adjacent the bottom;
- a double-walled cover extending across said cylindrical wall adjacent said top, at least one of said double-walled floor and double-walled cover including first and second coextensive walls spaced-apart along the axis of the presure vessel, said walls having circular edges abutting plates in said cylindrical wall;
- a ring disposed concentric with and between said first and second walls, said ring abutting at least one of said first and second walls;
- and a plurality of tensioned prestressing elements radially extending from said cylindrical wall to said ring.
