Description

Insulation refers to the field of instrumentation for the absorption, rectification, and dust collection processes.

A known apparatus for carrying out mass transfer processes, including a vertical body, inside which is installed at least a plate, made of a ring and a disk, located under each apyroMt between which contact elements are placed 1. The disadvantages of the known construction imply uneven distribution of the bone as the height of the zone contact of phases, and between contact elements and, as a result, shszka its efficiency.

The proposed design eliminates the disadvantages of the known apparatus.

The purpose of the invention is to intensify the process of mass transfer by crushing the liquid and to evenly distribute the liquid and gas along the height of the contact zone.

To this end, the contact elements are made in the form of radially arranged nozzles, the lateral surface of which

vvabzhena vertical slit installed with a gap in relation to each other and forming a narrowing channel between them for the passage of the gas-liquid mixture; the vertical slot is made with a variable section along the height of the contact element; the plate is provided with a pen distribution threshold; over a plate of ustszhled. a truncated cone, and under the plate - a pocket next to it; the adjacent plates are connected to each other by a cylinder.

FIG. 1 shows the mass transfer structure with one plate and a truncated KOiQrcoM cut-out; on isr, - section aa fet. one; in fig. 3 - node I of FIG. Ij in FIG. 4 - i design of mass transfer apparatus with several: plates, longitudinal section.

The mass transfer apparatus includes a housing 1 inside which a plate is installed, consisting of a disk 2 and a ring 3 located one above the other, between which are placed the nozzles 4, provided with a slit 5, the disk 2 and the ring 3 are interconnected by a cylinder 6 and have openings 7, 8 inlet nozzles

the nozzles of the Vyvod fluid E, a truncated cone 1Q, a redistribution threshold 11, njDHeMй pocket 12. Nozzles 4 can have a different section including a polyhedron, an ellipse circle, and combinations thereof.

Mass transfer apparatus with one plate works as follows. The liquid enters the apparatus through the nozzle 8 into the chambers formed by the wall of the housing I by the ring 3 KoiQTcoM 10, and enters the nozzle 4 through the openings 7. From the nozzles 4, the liquid flows through slots 5 in; the form of jets into the channels between the nozzles, For a uniform-l; pac-v limit of the liquid flow between the nozzles, the repartition {) isolating threshold 11 serves. The gas (vapor) coming into the apparatus from above, picks up the liquid flowing out of the slots 5, splits it into droplets into the channels between the nozzles 4. After the interaction of the phases gazr (vapor) - liquid

the flow is separated, and the liquid flows downwards, where it is removed from the receiving pocket 12 through the pipe 9 and the gas is removed. through the pipe.

In this case, on a plate, the gas-liquid flow from its center to the periphery is directed.

To achieve a high efficiency of the apparatus, j needs a uniform distribution of the gas (vapor) flow over the height of the phase contact zone, which in this case is achieved by the presence of a gap 5 in the side surface of the nozzles 4 with variable cross section, ensuring uniform spraying of the horse zone of the phase stroke with liquid. 3). In a multi-plate apparatus (Fig. 4), the countercurrent movement of phases along its height is carried out — gas (vapor) is fed from the bottom, and the liquid from the top, and direct flow on each plate, with

the direction of movement of the gas (vapor) - liquid flow on the adjacent plates is opposite.
