Description

The invention relates to the design of mass transfer devices.

A mass transfer annarat is known for the interaction of a gas (nara) with a liquid, the height of the body of which contains the plates with contact elements in the form of injectors. The disadvantage of such an apparatus is low load but phase.

The proposed device makes it possible to create an additional contact zone due to the fact that its bump stops are equipped with bubble combs located below the injectors, and the constant level of the fluid level is possible due to the contact elements of the inclined w side, which are up to the partition plate plane.

In the drawing, the proposed apparatus is schematically depicted.

It consists of a body / plate 2 with slit nozzles 3, bump stops 4 with bubble combs 5, parting 6 and drain 7 partitions.

The device works as follows.

With the passage of vapor through the nozzles of the plate, the intake slots of the injectors 8 capture the liquid and inject it. This forms the first mass transfer zone in the fine dispersed phase. On the surface of the baffle section of the baffle 4, the liquid is separated in the form of a thin film, which

action friction goes to the comb. In this case, a second zone of mass transfer is formed on the baffle in the zone of contact of the liquid film with steam. From the striker comb, the liquid drops into the bubbling zone, where a third mass-exchange zone of vapor and liquid forms. From the zone of active barbo-sa in the partition wall 6, the liquid flows to the plane of the plate. Then through the gap between the dividing partition and the plane of the plate, the liquid passes to the intake slot of the next injector, at the same time leveling the liquid level L but both sides of the dividing partition. On

In the 5 following plate elements, the cycle is repeated as described above. The liquid on the plate is poured from the drain pocket through the comb partition 9, the overflow of which is located below the slot of the insert, and the bottom section

0, the first injector of the tray and overflow, in order to calm the non-receding liquid, is the separation partition 6.

Subject invention

25

A mass exchange apparatus for interaction of gas (vapor) with a liquid, consisting of a body, plates with contact elements 30 in the form of injectors and arcuate baffles mounted above them, characterized in that, in order to intensify the process and maintain a constant level of liquid on the plate, they are equipped with bubbling combs located below the injectors, and inclined non-reaching to the plane of the plate partitions are placed with contact elements.
