Abstract
The case 2 of the container 1 having a vertical axis X-X contains two adsorbent beds 3,4 in the form of sleeves retained by three cylindrical grates 5, 6, 7. The intermediate grate 6 is axially rigid and radially flexible while the innermost and outermost grates 5,7 are axially flexible and radially rigid. This enables the container and the adsorbent beds to support without damage the successive heating and cooling stages in the course of the adsorbent regeneration stages. Application to the purification of large amounts of air intended to be distilled.
Claims23
A reactor, in particular a container for purifying fluid by adsorption, comprising a case which has an axis and defines a first region and a second region respectively for connection to a source and to an outlet of a fluid to be treated, said first and second regions being separated by at least one space containing an annular bed of particles of active material, said at least one space being defined by two grates and having the shape of a sleeve having vertical generatrices, at least one of said grates being rigid in the axial direction, the grates being free to expand thermally in the axial direction independently of one another, and the two grates located respectively in an innermost position and an outermost position being rigid in the radial direction.
An apparatus for purifying by adsorption, comprising a source of a fluid to be purified and at least one purifying container which comprises a case which has an axis and defines a first region and a second region, said first and second regions being separated by at least one space containing an annular bed of particles of adsorbent material, said at least one space being defined by two grates and having the shape of a sleeve having vertical generatrices, at least one of said grates being rigid in the axial direction, the grates being free to expand thermally in the axial direction independently of one another, and the two grates located respectively in an innermost position and an outermost position being rigid in the radial direction, an outer region of said regions of the container being connected to said source of fluid to be purified.
