    2. The device according to A.1 / dated by the fact that each horizontal plate is from a central support element
    The openings are made with stepwise decreasing thickness, and from the openings to the wall of the column are made with stepwise different thickness.
    The invention relates to mass transfer technology, in particular, to devices for carrying out adsorption and desorption processes in a liquid-solid system. A device for contacting a stationary solid adsorbent with a liquid is known, comprising a cylindrical column with adsorbent divided by horizontal gratings into layers / horizontal reflective plates of variable cross section arranged between the gratings with an opening in the zone of the smallest section in which the pipe 1 is installed. This device stagnates the liquid, thereby reducing the absorption efficiency of the liquid by the adsorbent. The purpose of the invention is to increase the efficiency of the contacting process by preventing stagnation of liquid. This goal is achieved by the device for contacting a stationary solid adsorbent with a liquid, including a cylindrical column with an adsorbent divided by horizontal gratings into layers placed between the gratings horizontal reflective plates of variable cross section, made with a hole in the - zone of the smallest section in which the pipe, provided with a liquid distributor connected to the pipe, made with gaps parallel to the reflecting plate, the central support element, are connected and with it and with the stacks of the column, vertical radial ribs dividing the reflecting plates into sectors, the holes are made in each sector of the reflecting plates, and the ratio of the plants from the hole to the support element and from the hole to the wall of the column is (2 , 9-1.3): 1. Moreover, each horizontal repressive plate is made with a stitch, then a decreasing thickness from the central support element to the openings and with a stepwise increasing thickness from the holes to the stitching of the column. FIG. 1 shows a horizontal section of the device, view from above; figure 2 - section aa in figure 1; figure 3- Section bb on figure 2. column 1 overlaps the entire area of its cross section; horizontal reits 2 and 3 are spaced from each other. Vertical radial fins 4 connected to the central support element 5 and to the walls of the column divide the reflecting plates into sectors. Each sector node is formed by ribs 4, element 5, grids 2 and-3, and column wall 1. Plates b and 7 connected to the ribs divide the sector node into two parts: upper and lower. Plate; to reflect the liquid consists of inner and outer parts. The upper part is connected to the element 5 and extends to the edge of the plate b, shown in the form of section B. The plate 7 is made in the form of sections 8-12 of different thickness. The outer part of the plate 7 extends from the wall of the column 1 to section 13. Sections 13-15 are also made of different thickness. The reflector plate is made with a hole 16 connecting the lower and upper parts (hole 1b does not have to cross the entire reflecting plate, a hole is enough); The opening 16 serves to pass the fluid into the distribution: either 17. Typically, the distributor 17 is a pipe or a distribution box that drains the liquid passing through the opening 16 from the system or adds outside the liquid to the liquid passing through the opening 16. The distributor 17. connected to pipe 18, which is connected to the pipeline, transferring material into or out of the system. Eighteen pipes are provided (one for each sector node). Use any number of sector nodes (preferably, they have six or more, so that you can maintain the structural flow of fluid within the system). The axis of the pie node 19 is the axis of element 5 and column 1 of FIG. 2. Lattices 2 and 3 are mounted horizontally
    (almost parallel) and at some distance from one another. They are connected to element 5 and column 1 by welds or supporting rods 20 supporting the grids and providing a moisture-tight seal between the grids, element 5 and the wall of the column 1.
    The plates 6 and 7 are located between the grids 2 and 3. The hole 16 divides the reflecting plate into two separate plates. If the hole 16 is small, then the reflecting plate is a solid piece of material. The thickness of the inner plate b decreases in sections 12, 11, 10, 9, and 8, and the outer plastic 7. increases in sections 13-15.
    Plates b and 7 divide the sector node, which is formed by ribs 4 and grids 2 and 3, into the upper 21 and lower 22 parts connected by an opening 16. In the opening 16 there is a distributor 17 with a capacity 23 connected to pipe 18. Distributor - 17 either removes the material passing from the upper part 21 through the opening 16 to the lower part 22, or adds material to this liquid. The pipe 18 is connected to the ribs 4.
    The proposed device is especially effective for processes in which a liquid passes between a large number of layers containing solid particles. Such processes include separation, in which the liquid is in contact with a solid adsorbent, which selectively adsorbs one of the components of the fluid's fluid, and the selectively adsorbed component is recovered from the adsorbent at the desorption stage. If the adsorbent layers are stationary, it is desirable to add and remove liquid from points located between a plurality of dense layers, while preserving the structural flow in the layers.
    With a structural flow, the fluid entering the adsorbed surfactant layer receives a uniform treatment, a passage through the layer. Structural flow is desirable in order to maintain a predetermined difference in the composition of the liquid in order to separate it into components, it is desirable to exclude the zones inside the layer of solid adsorbing particles in which. There is a gradual change in the amount of liquid as it passes from one zone to another. Maintaining a certain structural flow allows you to significantly change and predict in advance the composition of the fluid by the gradual transition through the layer.
    In addition, it is desirable to exclude localized high concentrations of the fluid components inside the dense layer when the fluid is introduced and withdrawn between the layers. The fluid added between the layers is mixed with the liquid passing between the layers. Such mixing is possible only when the device is located between the layers. This mixing helps to distribute the fluid introduced between the layers, providing a uniform composition of the fluid.
    A device separating the two layers of the adsorbent should ensure the removal of the liquid while maintaining the structural flow of the liquid in the layers.
    The mixing of liquids, the passage of 5 1CTIH between the adairbinding layers, occurs in Hole 16, which is small enough to cause a pressure drop across the opening i6 and causes the liquid to mix.
    0 In addition, the material added to the fluid passing through the opening 16 is mixed with the material passing through the opening 16 / due to a drop in pressure.
    five
    The enlarged cross-section (thickness) of the plate in areas remote from the hole 16 provides a relatively high velocity of the fluid in these places, which contributes to its
    0 removal.
    The structure is made of a metal that can support the weight of the adsorbent on the gratings. Diameter of cylindrical column from several
    5 centimeters to several meters, length & 1-30 m and more. The reference element: is a tube of the sky of the diameter, located along the entire height of the column, the grids retain particles with a diameter of 0.4-0.8 mm t.However, the dimensions of the openings of the grids can be provided. Frames or supports are provided to strengthen the grids). The height of the vertical edges, up to 1 m, preferably 5 to 8-13 cm. Liquid distributor. made in the form of a rectangular box installed between the gratings and connected to them.
    Liquid reflection plate
    0 is made of metal, placed between the grids and made with. a hole located between the support of the column wall, so that the amount of adsorbent in the annular space between the support and the hole and between the hole and the wall of the column is the same.
    The hole in the reflection plate has a rectangular
    0 shape and size, ensuring a permissible pressure drop during the passage of fluid through it. This hole may be a slit intersecting a plate to repel fluid between two ribs,
    dinennym with this plate. Four or more devices are placed along the axis of the column containing solids to separate them into several layers.
    The device is made as follows.
    A plurality of ribs are mounted on a central support. Twelve or more of them emerge from the central support and extend to the wall of the column or to a predetermined outer surface that is welded to or installed on the wall of the column, then the bottom grille is welded to the ribs. Thereafter, the liquid reflection plate and the distributor are placed inside the device, the upper grate is mounted on the fins and welded. The entire device resembles a disk with ribs extending from the center of the disk, with the upper and lower lattices parallel and also have a disc shape.
    A hole, a hole, or an empty space in the plate to reflect the liquid is located between the central support and the wall of the column. The hole can be round, elongated, oval or representative. contain a circular segment of the plate to reflect the liquid. This hole intersects the pie-shaped device unit.
    The lattices will be slightly deflected or bent, and yet they will be practically parallel. With a slight deviation of tenths of a degree (up to five degrees), the arrangement of the different parts in the device is considered to be almost perpendicular.
    In a preferred embodiment, the apparatus for use in the column has an inner diameter in the order of 6.6 meters. The central support element is made with an outer diameter in the order of 0.6 meters. The outer part of the support element is located about 3 meters from the wall of the column. The upper and lower horizontal grids are located at a distance of about 6.35 m from one another and are practically parallel.
    Forty-eight vertical ribs connected to the supporting element extends towards the wall of the column and form 24 sector nodes. Between each group of ribs there is one distributor.
    mounted in the hole of the reflecting plates. The distributors are connected to pipes that pass through the upper grid into the layer above this grid and out of the column. The pipes are installed at equal distance from one another along a circle with a radius of 2.4 m.
    In each sector node, a horizontal plate for reflecting fluid is located between the gratings and is divided into internal and external reflective plates, as shown in the drawings. The inner plate is welded to adjacent fins, and it has four sections, the thickness of which decreases from the center to the hole. The first (samp thick) section, located closest to the support, has a thickness of about. 2.5 cm and 74 cm long, the second section connected to the first one is about 1.9 cm thick and 46 cm thick, the third section is about 1.3 cm thick and 46 cm long, the fourth section has a thickness of about 0, 64 cm, length 41 cm and ends at the hole.
    The very thickness of the outer plate section is connected to the inner wall of the column and has a thickness of about 2.5 cm and a length of 38 cm, and a second section with a thickness of approximately 1.9 cm and a length of 30 cm is connected to it. 25 cm and ends at the hole. .
    The hole in the plate has the form of an arc about 12.7 cm wide with a radius of about 2.4 m, its center lies on the axis of the column.
    The distributor, located in the hole between the inner and outer reflective plates, has exits facing the edges of the plates.
    The proposed device is used when low and uniform velocities of a liquid passing through an annular layer of solids are desired, when extremely low velocities of the liquid and the inner and outer boundaries of the layer are unacceptable and when all liquid removed from the layer of particles should be collected and mixed with another liquid, t . outside the system.
    As a result of preventing localized high concentrations of various materials in the contact stage in the proposed device, the working efficiency is significantly increased.
