Abstract

The invention relates to the chemical industry and can be used in other fields, such as petrochemical, food etc., for cooling, heating, cleaning, gas absorption, separation of liquid mixtures into components and other processes. A heat and mass exchange apparatus comprises a body with pipes for inlet and outlet of light and heavy phases, contact elements - swirl plates installed inside the body, each of which consists of the upper part in the form of a web with radially arranged rectangular openings closed at the top by guide plates, around which on the web perforated cowlings are installed, and the lower pat divided by annular and radial partitions and a bottom into sections, on which nozzles are radially arranged for intermediate removal of heavy phase. The upper and lower parts of the contact element are connected by an overflow pipe with slots for removal of heavy phase on the lower part of plate, and nozzles for introduction of light phase are located between the upper and lower parts of the contact elements, in the case between the contact elements conical perforated partitions are located coaxially with the body. The invention provides for increase of contact area of phases due to creation of an additional interface in the area of conical perforated partitions, that increases output of the apparatus, and allows to use thereof both for pure liquids and suspensions containing solid particles and crystals.

Description

- the complex design of the fluid turbulator, and the radial slits of the canvas 7, hits the slope, the presence of nozzles does not allow working with the suspension plate 8, which closes the slits from above, with swirls containing solid particles and crystals. is heard and twists the heavy phase located on

The purpose of the proposed invention is to create a vortex plate. A more complete mixing of the heat and mass exchange apparatus, in which the ring perforated partition contributes to the mixing of the phases 9. the organization of an additional phase contact surface. The heavy phase enters the TMA through nozzle 2, which is used both for pure liquids and for solids, and then moves along the plate from the periphery to suspensions containing solid particles and crystals. center, through the central hole in the canvas 7 and the

The task is solved by the fact that the plasma exchange apparatus, which contains the housing from the lower part of the vortex plate, falls into the slot in the drain nozzle 10. The lower part with nozzles for the input and output of a light and heavy vortex plate has sections limited by the bottom 11, which phases, contact elements - vortex plates, ring partitions 12, 13 and radial ones are installed inside the body, each with a vortex partition 13. If necessary the important part from the upper part in the form of a sheet from the radial phase is taken from the plates through nozzles 15. but located by rectangular slits, the processes of heat and mass exchange between heavy and light guide plates covered from above, phases in TMA are intensified by conical per- around which on the canvas are installed perforated partitions 16, which are installed custom, and the lower part, separated by a ring- between contact elements (plates). with radial partitions and the bottom on the section.
