    The system to make walls for catalytic baskets for heterogeneous synthesis reactors, particularly the distribution walls which are inserted in axial reactors in order to modify them into substantially radial (or axial-radial) reactors with low energy consumptions, consists in dividing the distribution walls (DW) into n sections, and by attaching each section end to a device consisting of two flange elements (1, 2), the radially longer one protruding over the distribution wall achieving the truing and stiffening of the entire device, the other one extending slightly into the inside of the catalytic bed. Between the internal walls of the basket (Si/CN) and the perforated distribution sheet (DW) an airspace (I) is formed by using separating rods (DI) or, in their absence, using a perforated bridge plate (LFP) as the distribution wall.

    专利说明:

    The invention relates to a catalytic basket design for heterogeneous synthesis reactors.
    The aim of the invention is to increase reliability.
    FIG. 1 shows a schematic representation of the proposed basket, a longitudinal partial section; in fig. 2 is a section A-A in FIG. one; Fig 3 - the node I in Fig about 2; fig 4 is the same, (airspace creation option); in Figs 5 - part of the perforated bridge wall; FIG. 6 shows a section BB in FIG. five"
    The reactor comprises: housing 1, cartridge 2, a plurality of catalytic layers 3 C increasing in height from the upper to the lower layer, a gas distribution shell; 4 with perforations
    over the entire height of the layer, the inner perforated shell 5, the central tube 6 and the heat exchanger 7 with the pipe. com 8o The gas distribution shell 4 is made of separate circular W polygonal sectors 9, equipped with flange-sh 10 and 11 on two end sides, forming flange connections with flanges of neighboring sectors, and a grid 12 forming an air gap 13 with the gas distribution shell 4 due to the installation of dividing rods 14, which are welded to the gas distribution shell in the perforated bridge wall. The fixation of the entire device is carried out using a tiuiaH- connection, which is kept from the bottom 10 and 11, ss are connecting each other

    with the other at the inner end using locking or locking means, for example with a bolt 15, and which do not have matching ends, the other End Flange 10 is longer in the radial direction than the flange 11 and is welded to the perforated plate 6
    The flange 10 has a continuation of 16 and IQ can freely approach or move away from the inner surface of the housing 1 so as to compensate for thermal expansion. The flange 10 centers and tightens all the fixing device and serves as the basis for welding at the end of the mesh section 12. Flange 11 is welded to the distribution shell 4 "
    The flange 11 is also welded to the other 2 nd end of the 12 сетки mesh section. The mesh 12 wall is divided into sections according to sectors 9, each section being attached at one end to the alignment or centering part 10 and 25 at the other end to the part 12c. and the corresponding sectors 9 are obtained by welding the separating rods 14 to the solid portions of the -jQ sectors 9 between the mesh holes 17, or by making the gas distribution shell in the form of a corrugated plate. Instead of a corrugated perforated plate, an additional perforated plate 18 and raised sections 19 can be inserted, fastened to the gas distribution shell 4. Between the surface of the plate 18 and the surface of sections 19 there is a dd limited gap 20o
    The zones in which gaps 20 co-create are spaced apart from each other, i.e., they are not over the perforations of sectors 9, as a result of which the gas, which passes radially, travels a minimum axial distance and passes
    35


    through the gaps 20 and 21 in the perforation 22 of the grid 12,
    The device operates as follows.
    Fresh gas enters through the pipe 23, rises through the air space 13, is heated in the heat exchanger 7 with hot gas, flows through the tube 6, a small part of which penetrates into the catalytic layers open from above, and crosses the first shorter upper part at the height HJ H - in the axial direction, and most of it crosses the height AND in the radial direction.
