SU1210873A1 - Reaction tray for interaction of gas (vapour) with liquid - Google Patents

Description

  1210873 invention relates to a device for a data transport from one time to another.

you for mass exchange processes and can be used in the chemical, food and other industries for absorption and rectification processes.

The purpose of the invention is to increase the efficiency of mass transfer due to uniform distribution of the liquid film over the cones.

FIG. 1 shows a contact plate in a column, longitudinal section}

in fig. 2 - contact elements, general view.

The contact plate consists of a straight 1 and a reverse 2 perforated cones. On top of each cone at some distance from each other, vertical annular partitions 3 are installed with openings 4 in the lower part. The cones are connected by their bases with an annular shell 5 with the formation of a bead above a straight cone. The inner peripheral parts of the cones have annular partitions 6 and 7. The partition 7 of the reverse cone is installed in front of the partition 6 of the forward cone prior to the start of perforation.

The device works as follows;

i The liquid flows to the top of the straight cone 1 and spreads over its surface in the form of a film. Reaching the annular partition 3, the liquid spreads along it and through the opening

These at the bottom of the septum spread, uniformly irrigating the surface of the plate, and so. until the next transfer. On the peripheral part, accumulating on the side of the annular shell 5, the liquid flows through the annular partitions 6 and 7 on the inner surfaces of the cones, enters the reverse cone 2 and moves from the periphery to the center, evenly distributed over its surface due to the annular partitions 3 holes 4. From the top of the opposite cone 2, the liquid flows to the underlying contact plate and repeats its path. The gas moves upwards and is in contact with a film of liquid flowing along the surface of the cones. Due to the presence of partitions 6 and 7, which form a water seal, gas breakthrough in the peripheral part of the plate without contact is eliminated.

The angle of the forming cones and the size of the perforations of the holes on the annular partitions are selected depending on the performance. A large living section of the plate provides a small hydraulic resistance, and such a mutual arrangement of the forward and reverse cones allows the fluid to move from the center to the periphery of the column and from the periphery to the center during constant contact with the gas, which makes it possible to efficiently use the volume .
