Description

The invention relates to instrumentation of heat and mass transfer processes in a gas (vapor)-liquid system, such as absorption, moistening of gases, rectification, etc.

The purpose of the invention is to intensify the process of heat and mass transfer by equalizing the gas pressure over the cross section of the apparatus.

FIG. 1 shows a heat and mass exchange apparatus; in fig. 2 is a section A-A in FIG. one.

Heat and mass transfer apparatus contains a cylindrical body 1, inside which is mounted a hollow shaft 2 connected to a drive 3. On shaft 2, perforated discs 4 are installed in pairs to form

The racket is grasped and lifted by the pockets 6, poured out of them and lowered under the action of gravity into the lower part of the apparatus, moves to the exit of the section.

g Then the liquid enters the new stage of contact and so on. Having thus passed all the stages of contact, making a huge way at that and constantly contacting the gas (vapor), the liquid is enriched with a high boiling component, impoverished

10 is low boiling and is discharged from the apparatus through the nozzle 10.

Steam (gas) after contact with liquid in the section with the nozzle gets on the blades 7, mounted on the shaft 2. The blades of steam (gas) are additionally mixed with the medium of the section, filled with the nozzle 5. On the composition, redistributed and the periphery of the disks are strengthened the pockets 6. enter the contacting with the fluids. Between the sections with the nozzle 5, the blades 7 are mounted on the shaft 2. Partitioning rings 8 are made on the body 1. The body 1

bone to a new stage of contact phases. This compensates for the loss of vapor pressure at the previous contact stage, and the steam with

has nozzles of an inlet 9 and an outlet of a 10th, with a fluid velocity that moves on the bone, an inlet 11 and an outlet of gas (steam). A new section with a nozzle. This allows

The body 1 of the heat and mass transfer apparatus is able to carry out the process of mass exchange when it is not formatted at an angle of 1-5 ° to the horizontal. Relative phase velocities throughout

The heat and mass transfer apparatus works for the length of the apparatus, which is largely

as follows. it intensifies the process. Passing all the steam into the working volume of the device after the contact of the phases, the steam, after giving high boil through the pipe 11, the liquid (into the fluid component and enriched

rectification - phlegm) - through the pat-low boiling component, is derived from

logging 9. On the hollow shaft 2 in the apparatus through the nozzle 12.

feed mixture comes. Liquid flows Application of the proposed heat and mass at the bottom of the apparatus. With the rotation of the exchange apparatus of the horizontal type

shaft 2 is seized by pockets 6, 30, which drastically reduces installation costs, reinforced along the perimeter of the perforated-repair, since repair of the known column mass-exchange equipment of hard-working disks captured by the pockets, since the apparatus is broken by sectioning rings 8, which restrain the liquid and 35 prevent its penetration.

1. Heat and mass transfer apparatus comprising a drive, a cylindrical body, inside which disks are mounted on the shaft, 1. Heat and mass transfer apparatus comprising a drive, a cylindrical body, inside which disks are mounted on the shaft, During the rotation of the sections with the nozzle 5, the liquid is poured out of the pockets 6, which evenly irrigates the nozzle. When d branch pipes input and output phases, distinguishing this drop and a film of liquid, flowing so that, in order to intensify heading, moving along a long and complex heat and mass transfer process due to a vratraktori m, constantly in contact with the gas. gas pressure lowering over the cross section of the apparant. laziness of fluid flow, which is facilitated in pairs, to form a section, it is actively mixed and renewed 45 filled with a nozzle, pockets are reinforced along the perimeter of the discs, and the case is equipped with blades m mounted on the shaft and sectioning rings placed on it. 2. The apparatus of claim {. The housing 1 of the apparatus is installed at an angle of 50 that it is installed at an angle of 1-5 ° to the bare horizon. Therefore, a liquid that is rizontu. phase contact surface, which intensifies the process of mass transfer. The gas moving in the section with nozzle 5 is also transported and turbulized by the nozzle. The racket is grasped and lifted by the pockets 6, poured out of them and lowered under the action of gravity into the lower part of the apparatus, moves to the exit of the section. Next, the liquid enters the new stage of contact and so on. Having thus passed all the stages of contact, making a huge way at that and constantly contacting the gas (vapor), the liquid is enriched with a high boiling component, impoverished low boiling and is removed from the apparatus through the nozzle 10. Steam (gas) after contact with a liquid in the section with a nozzle gets on the blades 7, mounted on the shaft 2.
