Description

The invention relates to devices for absorption and distillation columns in the chemical, petrochemical and petroleum industries.

The objective of the invention is to improve the cooling of the plate of the absorber, increasing the strength of the plate with hydraulic shocks that occur when the gas medium is supplied to the liquid layer of the trough of the plate.

This is achieved by the fact that the lower trough-like bottom of the plate is equipped with a jacket where the coolant is supplied, as well as fittings with tubes through which the coolant is supplied and removed to the jacket of the trough-like bottom.

In FIG. 1 shows the design of a plate for an absorber.

The plate contains a water lock 1, a perforated disk of a plate 2, a cap 3, a guide cone 4, a diffuser for introducing gas into the plate 5, a trough-like bottom of the plate 6, a pipe for supplying coolant to the bottom of the plate 7, a shirt of the trough-like bottom of the plate 8, a fitting with a shut-off a body for draining the coolant from the shirt bottom plate 9, a fitting with a locking body for draining the coolant from the shirt plate 10, overflow pipes for transferring liquid from the plate to the underlying plate 11, pipe for the exit of coolant from the shirt bottom plate 12.

The device operates as follows.

The gaseous medium is pumped into the plate through the diffuser (5) and enters the liquid layer, which fills the plate trough, flowing down from one plate to another through overflow pipes (11). The gas phase sparges through the layer of the liquid phase, as a result, mass transfer occurs and the concentration of the liquid phase increases, for example, during absorption.

Since the absorption process proceeds with the release of heat, the mass of the plate is cooled by a refrigerant, which is fed into the plate jacket (8) and, having removed the heat, is removed from the jacket. From the bottom of the last plate, the liquid phase of the desired concentration is discharged from the apparatus into the absorber.

Since mass transfer between the liquid phase and the gas phase occurs inside the plate during rapid boiling of the liquid, it is mass transfer very effective. And since the entire mass of the plate is cooled or heated, heat transfer is also effective. In this case, the heat exchange in the absorption or distillation columns does not require the installation of additional devices, such as coils, which are stacked on a plate.

Claims (2)
