Description

The invention relates to chemical technology apparatuses for carrying out the processes of distillation, distillation and absorption, and also to be used in the refining and petrochemical industries.

A mass transfer apparatus is known, which contains a vertical case, sectioned with plates with holes, liquid nozzles, fixed in the holes of the plates, caps placed above the nozzles, overflow pipes and drain pockets. Each box is equipped with installed coaxially inverted glass, on the outer side of which is placed; spiral-shaped contact trough and arc-shaped tubes.

The disadvantage of this apparatus is the design complexity.

names This is due to the fact that the bubbling mirror is 2 to 3 times smaller than other types. Therefore, the local vapor velocity is much higher than the average. The vapors detach vertically from the surface of the liquid. To prevent the dripping of liquid droplets with slots (hl) overhead &# .g, -№

The spherical plate needs to increase the distance between the cells.

The goal of i-co-fluents is to increase the efficiency of mass transfer by using the effect of separating particles of a liquid in a centrifugal field.

This goal is achieved by the fact that, on the nozzle, coaxially arranged, pressed to each other, single-turn pipe coils, evenly placed around the circumference by the inlet from under the cap on top and exit from the bottom.

In comparison with the known, the proposed mass transfer apparatus is distinguished by the location of single-pipe tubing coils on the nozzle, extending from under the cap and evenly spaced around the circumference by an inlet from the top and an exit from the bottom.

The gas (steam) from the bottom passes through the nozzle 3 under the cap 5. From under the cap 5, the gas (steam) is distributed to the inputs of the multiple-use pipe coil A. The passage through the multi-pass single-turn pipe coil, the gas (steam) is separated due to the centrifugal force the lower ends of the coil are bubbled through the fluid on the plate. The height of the liquid on the plate is maintained by drain partitions 6. The bubbling liquid is fed to the upper plate and flows from the overlying plate to the lower one through the drain pocket 7.

The passage through the coils, the gas (steam) due to the centrifugal force is also separated due to the high velocity of the gas (steam) in the coil and the larger heat exchange surface, the heat exchange between the liquid on the plate and the steam (gas) in the coil increases cap, thus increasing the efficiency of mass transfer.
