The invention relates to the creation of devices for mass and heat transfer, and more particularly the invention relates to the creation of the columns containing the components inside of the filler in the structural fault or form. Such fillers typically rest on the base plate (the plate) mounted on the bottom section of the filler. It is to such anchor plates and is relevant to the invention.

The base plate is usually a single design or construction formed of multiple welded Leary cases you are required to provide passage of fluid flow only in one of two directions, while in other cases, the column may be opposite stream of gas and liquid. If the flow in any direction becomes excessive, even for a short period of time, the base plate may be damaged and its function may deteriorate. It is therefore important that the base plate had a stiffness that was provided rather its internal design, and not near a one-block elements, which are held together by gravity.

In U.S. patent US-A-3,222,040 disclosed base plate Assembly which is made using a blend of perforated elements in the form of an inverted U, which have branched flanges mounted on racks stiffness of appropriate sizes.

In U.S. patent US-A-4,171,333 described is similar to U.S. patent US-A-3,222,040 design with holes of a special form.

In the patent EP 0 495 418 A1 described support layer consisting of elements that also have the shape of an inverted U, with holes on the top and side walls.

Known base plate (U.S. patent N 5132055, including many channel beams with a cross-section of mainly U - shaped, which has a patch Pleskov the s beam are parallel to each other.

In accordance with the invention provides for the creation of new design elements to a base plate, which base plate can be manufactured without welding; these elements easily can be manufactured simply and can be easily assembled and dismantled inside the column. A base plate, which is constructed using such elements have during their operation high rigidity and resistance to moving forces.

In accordance with the invention provides for the creation of non-welded element base plate, which includes an elongated (extended) channel beam with a cross-section of mainly U-shaped form, which has perforated side walls and adapted for quick connection in the area of the open ends of the channel beams to the adjacent beams, which lie parallel to this beam and in contact with each of the sides.

When using the elements of the channel beams combine with each other in such a way as to contact the upper part of the sides of the channel beams. These parts are made with fast their connection to each other due to the fact that predusmotrennij, such as a bolt-nut connection, cotter pins, C-shaped clamps, etc. may be used to join together channel beams in at least two locations along their continuous lengths. In order to facilitate installation of the mounting channel beam mainly has at its open end adjacent to a U-shaped cross-section, the area in which walls are parallel.

Channel beam is mostly flat area of the base, which is already the distance between the open ends of the channel beams. This flat plot of the base provides a reliable connection with the supporting means within columns, on which rests the assembled base plate installed in its operating position. The supporting means is usually a ledge that goes around the inner surface of the column at the correct height.

The area of the base element base plate is connected with a plot adjacent to the open ends of the element, by means of inclined side walls which are provided with holes for passage of fluid flow during operation of a base plate, made of channel beams. In that case, when the operation involved two-phase protivoproteinaya. In practice, this may mean that the area of the holes should be about 60% or more of the cross-sectional area of the column. The degree of inclination of the side walls is dictated by the relative size of the open end and preferably is the same for both sides.

When working with two-phase opposite stream, it is desirable to provide openings at the base of the channel beams to allow for drainage of liquids through the support plate. However, the number of such holes should not be too large, or such openings should not be located too close to lead to a significant weakening of the structure. This hole should be wide enough to let liquid without the formation of pressure fluid, which could cause the fluid to flow into the openings in the side walls. Usually it is enough that the holes ranged from approximately 7 to approximately 10% cross-sectional area of the column.

Additional preferential hardening characteristic is preserving bent inward at a right angle bends (flanging) on each of the upper ends of the channel beams. This helps to provide soprotivlenie in the baseplate structural strength of the channel beams, with the above-mentioned inclined side walls, can be further enhanced by the provision of the end closing plates in the form of isosceles triangles with connecting flanges running along the equal sides (triangle), and these guard plates are designed to fill the space between the sloping sides of the adjacent channel beams and can be attached using the aforementioned mounting flanges to the two channel beams. These guard plates will also close the space s between the channel beams, preventing transmission of the components of the filler down through the block base plate. For the installation in this case can be used the same fastening means as used to connect adjacent channel beams at their open ends.

In Fig. 1 presents a perspective view of the preemptive variant of implementation of the channel beams in accordance with the invention; Fig. 2 is a cross section of the base plate, made of channel beams, shown in Fig. 1 when it is installed in the reaction column.

In Fig.1 shows a channel beam 1, which has a mainly U-shaped cross CE is receiving the distance between them with increasing distance from the base. Side walls of the end sections parallel walls 2, each of which is equipped with going inside flange 3. Lots of parallel walls with loads placed at a certain distance of the holes 7, which can be entered fastening means in the form of a pair of bolt-nut. Sloping walls have a lot of holes 8 which are adapted for easy passage through them of liquids or gases. In the area of flat ground 5 can also be provided with holes 9 for drainage of fluid. End plates turned down very low 6 pairs of bolt-nut 10 to the side walls adjacent to the open ends of the channel beams.

In Fig. 2 shows the column of the assembled base plate containing three channel beams, shown in Fig. 1 and additionally containing from each of the ends of the half of the channel beams of the same design, and the site is flat with the bottom of the half of the channel beams rests on the support ledge 20, mounted on the inside wall 21 of the reaction column.

The material from which can be constructed channel beam, to a significant extent depends on the environmental conditions in which it is operated. With regard to the weight of the filler, which supports the stainless steel column steel. However, in appropriate circumstances, can be used and other materials.

During operation, the base plate can be used to support components of the filler, optionally, structural fault or form. You should pay attention to the fact that the base plate without any difficulties can be assembled and dismantled in a limited space, and can also be used in many different configurations. Therefore, it is an extremely adaptive and flexible design of base plates for the reaction columns.
