Description

The utility model refers to the construction of bulk packings for mass transfer apparatus and can be used in treatment facilities, in aquariums, reservoirs, in energy, chemical, oil refining, petrochemical and other industries in the implementation of heat and mass transfer processes in liquid-vapor (gas) systems.

A known filler element for packed columns (patent document RU 177035 U1). This device, among other things, can be made of various materials (polypropylene, metal, etc.) in the form of an ellipse, consists of two parts, has wave-like ribs and at least one through hole. The disadvantage of this solution is the small diameter of the hole, which does not allow water to circulate freely inside the filler and the shape of the ribs with sharp alternations of depressions and depressions, which, among other things, contributes to the adhesion of the filler elements to each other and the formation of stagnant zones.

Known filler element for packed columns (patent document RU 2656483 C1), presented in several versions, contains a central partition dividing the element into two parts connected to the partition and located on each of its sides parallel ribs. The plane of each of the ribs has alternating projections and valleys directed in opposite directions. The partition has at least one through hole. On the partition along the axis of its symmetry, at least one bridge is installed, the plane of which is perpendicular to the plane of the partition. Between the main protrusions and depressions of each of the ribs at the place of their height difference and transition from the main protrusion to the depression and vice versa, additional protrusions and depressions are made, forming, together with the main protrusions and depressions, a common wavy surface. The disadvantage of this solution is the smoothness of the ribs with longitudinal additional protrusions and depressions, which, together with the small size of the ribs, reduces heat and mass transfer in the system.

A device for a similar purpose is known (patent document (RU 98339 U1) of a spherical shape, containing a central partition in the form of a circle, dividing the element into two hemispherical sections connected to the partition and located on each of its sides wavy ribs of variable width, a central through hole is made in the partition , on the partition along the axis of its symmetry, a bridge is installed passing through the hole, rod-shaped elements are made in the central ridges of the undulating ribs.The disadvantage of this known device is the unreliability of the structure, the possibility of deformation of the element, the occurrence of engagement of the ribs of the filling elements with each other with mutual penetration of the elements one into the other and as a consequence, a decrease in the efficiency and intensity of heat and mass transfer processes.

Known Nozzle for heat and mass transfer structures (patent document RU 0000199476), made in the form of a hollow ball with round holes in its walls. The disadvantage of this device is the smooth shape of the filler, which reduces the volume of liquid evaporation.

Known Corrugated ball (patent document CN 209222146) spherical shape with rods, ribs, a through hole. The disadvantage of this device is that its ribs are of a rigid annular nature, which facilitates the adhesion of the filler element to each other and the formation of stagnant zones, as well as a small through hole that prevents the circulation of liquid in the filler.

The closest analogue of the claimed solution is Spiral random packing (patent document No. CN206334671). This device is characterized in that it contains an outer ring, a fixed buckle, an inner spiral strip, an opening window, a tongue and an outer ring, and is provided with an inner spiral body. The disadvantage of this product is that it entirely represents the intersections of smooth spiral shapes, which significantly reduces the evaporation area, in contrast to solutions with protruding parts - ribs.

The technical result of the proposed utility model is the elimination of these disadvantages, an increase in the efficiency and intensity of heat and mass transfer processes.

The "Filler element for packed columns" submitted for registration is a single piece of high density polypropylene, has a spherical shape, the diameter of the element is 55 mm, contains a central partition dividing the element into two parts, connected to the partition and located on each of its sides spiral ribs 1.4 mm wide. at the central septum, tapering to 1.3 mm. at the rod, located at an angle of 24 degrees, having alternating projections and depressions directed in opposite directions, a rod. A through hole with an external diameter of 10 to 50 mm and an internal diameter of 5 to 30 mm is made in the partition.

Figures 1-2 show the drawings of the utility model, where:

1- Partition;

2- Spiral ribs;

3- Rod;

4- Central hole.

Figure 1 is a top view of a Packed Column Filler Element. It can be seen from the drawing that most of the element is occupied by the central opening (4), which makes it possible to ensure a smooth flow of liquid inside the filler, and spiral ribs (2) located on both sides of the partition (1) at an angle of 24 degrees provide an increase in the evaporation area in comparison with analogues, and also due to its shape, they do not allow the filler elements to adhere to each other, the main width of the ribs is 1.3 mm. The rod (3) holds the structure of the utility model.

Figure 2 is a side view of a Packed Column Filler Element. The drawing shows the connection of the spiral ribs (2) around the baffle (1), their symmetry and smooth transition on both sides of the baffle. The width of the ribs at the partition is 1.4 mm.

The degree of bending of the ribs (24 degrees), their shape and width ensure the maximum efficiency of liquid evaporation up to 530 sq. Cm, from one element (for analogues - up to 340 sq. Cm).

Figure 3 shows a general view of the utility model.

When using this filler element for packed columns, the liquid is distributed in a thin layer over the surface of the ribs, which increases the evaporation area. Large hole with an inner diameter of 5 mm. up to 30 mm., outer diameter from 10 mm. up to 50 mm. increases the possibility of liquid circulation between the layers of the filler elements, and the spiral shape of the ribs does not allow the filler elements to catch on each other, and also increases the evaporation area. The combination of these characteristics provides an increase in the efficiency and intensity of heat and mass transfer processes.

The presented utility model is industrially applicable; Figures 4-6 show its implemented sample.
