The invention relates to the field of petrochemical and gas industry, in particular to the separation, the contact and separation nozzles of heat and mass transfer apparatus, and can be used in the processes of contact between phases, mainly in: - gas-liquid separators, the separators immiscible liquid mixtures, predominantly horizontal type.

Known multilayer nozzle movement phases along the contact and out of contact elements. The first is usually applied in a vertical apparatus, and the latter is in the horizontal, where there are restrictions on the height of the apparatus. The proposed invention relates to a multilayer nozzle movement phases through the layers. Known multilayer nozzle movement phases through them for separators, made in the form of parallel spaced mesh and filamentous packages attached to frames with retainers (and.with. 599825, 1044313, 1404096, RF patent 2006263, class B 01 D 45/08, and.with. 1393454, class B 01 D 45/00, U.S. patent 3006436, CL 55-233. The main disadvantages of these devices is the complexity of manufacturing the nozzle, the need for multiple layers for efficient separation, or contact, the unreliability of fixation.E. disadvantages by simplifying the mounting of the contact elements (threads) for a total rod holders. However, the limitations on the complexity of the manufacturing process due to the necessary bandwidth of the threads in the openings of the grooves, the presence of multiple layers (frames), gutters, poor contact due to the different density of the threads in the frame are stored.

The invention is directed to creating simple, not time-consuming in manufacture of the multilayer nozzle of the flexible elements, with the passage of the phases through which are provided a good wettability of the contact elements and the drainage of liquid.

The solution of this problem is achieved by the fact that mass transfer in the nozzle containing lattice frame packages with flexible contact elements fixed in frames with the help of clamps, each flexible contact element made of porous harness in the form of a snake, forming a series of alternating vertical rod contact elements, alternately interconnected at the top and bottom in places of fastening to the frame by clamps, and the fact that porous harness is made hollow, and the vertical rod contact elements in the cross section of the nozzle are equilateral triangles with a pitch equal to or less than two diameters of the loom, moreover, at least one nanoperiodic parts rum, and their length corresponds to the gap between the contact elements.

The proposed design of the nozzle is easy to manufacture. The frame may be made of sheet material, clamps length corresponding to the gap between the contact elements are bent or stamped on the crossbars of the frame and provide a simple and reliable fastening of the contact elements on the frame without rotation. The execution of the contact elements in the form of the microstructure of the bulk harness reduces the number of packets in the nozzle, allows an increase in their height without disrupting the fluid with the contact elements, which eliminates the need for the nozzle section height and eliminates the presence of the grooves, as in this case, the nozzle is placed on the base unit or pallet and allows an increased amount of liquid in gas, ensuring eat it on the first frame, allowing large load on the fluid in the porous volume of the loom.

The applicant is not known from the existing prior art nozzles, which simplify the design, reduce labor costs in the manufacture and improving the efficiency of the device was achieved in this way.

In Fig.1 presents a General view of the multilayer nozzle.

In Fig.2 - package n package 2 of the frame 3 is fixed between the upper 4 and lower 5 jumpers frames on the tabs 6 of the contact elements 7 of the porous harness, placed the snake on one side of the frame.

Frames form the package 2 in which the contact elements 7 are arranged on an equilateral triangle (Fig.2). The nozzle is placed on the pallet 8 and the top cover is closed 9.

Multilayer nozzle operates as follows.

The gas stream containing drip the liquid supplied to the nozzle. The gas passes between the contact elements 7, drops due to fluid inertia forces are deposited on the contact elements. Wetting the microstructure of the nozzle, the liquid is retained therein due to the surface tension forces and cannot be broken by the gas flow. The filling volume of the microstructure, the liquid accumulating flows through the contact elements on the pallet or bottom of the device, from which it is discharged. Separated from drops of liquid gas enters the adjacent packages, where it is additionally separated liquid droplets, and is collected in the form of the finished product.

Multilayer nozzle can work in the separator for immiscible liquids, for example, to separate heavy liquid phase from light.
