Abstract
The crown element for securing a packing in a mass transfer column comprises an elongate sheet which comprises a roof element, a wall element and a bottom element. A first bending line is formed between the roof element and the wall element and a second bending line is formed between the wall element and the bottom element. Incisions are formed in the roof element and grooves are formed in the bottom element. The number of incisions is smaller than the number of grooves.
Claims14
A crown element for securing a packing in a mass transfer column comprising
- an elongate sheet having a thickness of from 0.05 to less than 0.2 mm and including a wall element, a roof element extending from said wall element with a first bending line between said wall element and said roof element and a bottom element extending from said wall element with a second bending line between said wall element and said bottom element,
- said roof element having a plurality of incisions to separate said roof element into a plurality of elastically deformable roof element segments,
- said bottom element having a plurality of grooves to separate said bottom element into a plurality of elastically deformable segments wherein the number of said incisions is smaller than the number of said grooves, and
- said wall element comprises a plurality of first surfaces of triangular shape, a plurality of second surfaces of trapezoidal shape disposed in alternating manner with said first surfaces longitudinally thereof and a plurality of bending lines each said line being disposed between a respective first surface and a respective second surface.
