Description

one

The invention relates to rotary-disk mass-transfer apparatus for carrying out the extraction in the system "liquid-liquid" used in various fields of chemical, petrochemical, pharmaceutical and food industries.

Rotary-diskys extractors are known in which dispersing disks are mounted on the shaft, which runs along the axis of the extractor, and alternate with horizontal colpine walls, which are equally spaced along the height of the column.

There is a known colorant extractor, consisting of 1PI from the body, along the axis of which the shaft passes a fixed shaft with fixed dispersion elements, and the disjoint element is made in the form of a mesh plate with peripheral radial strips and an overflow pipe fixed along the center of the plate, the lower part of the lateral bead .The property of which is perforated. However, the extractor has significant longitudinal mixing, which reduces the driving force of the process and causes the need to increase

geometrically.X sizes of massoomania apparatus.

The purpose of the invention is to intensify the extraction process by enhancing the transverse cross section. 1.

This is achieved by the fact that horizontal dispersing disks provide for 1 cinipa.ib slots, and niapnnpno fixed perforated perimeter devices are located on the periphery of the dispersing disks of the cross pattern.

It is advisable to make cruciform cross-cutting devices in the form of frames with wire mesh. In addition, the cruciform mixers can be triangular.

FIG. I depicts a rotary disk extractor, a general view; in fig. 2 - dispersing disk; in fig. 3, 4 - - variants of pulper mixing devices.

The extractor comprises a housing 1, an upper and a lower cover 2, distribution devices 3 for uniform phase distribution, a rotating shaft 4, passing along the axis of the housing 1, which is mounted in the lower support 5 and the upper support 6. stator

.ii, iui In the form of horizontal annular partitions 7, nozzles for insertion 8 and 9 and removal of 10 and 11 phases, disiergating diks 12. The horizontal surfaces of the disks 12 have spiral slots 13, but the periphery of the dienergistic disks are located and alternating devices 14, which can be made in the form of a frame 15 with a blue. 16 mesh.

The extractor works as follows.

The heavy phase is through input 9 and disassembled 1 st. 1 household 3 into the upper part of the extractor. The light phase is fed through the inlet 8, the lower distributor 3 and it rises countercurrently to the movement of the heavy phase. Below the bottom of the lower device 3 lies the separation zone. When the rotor-disk extractor is working, the hard phase gets on smooth disnergating disks 12.

If there is a slot 13 in the disks 12, a part of the heavy phase will slip under the dispersing disk, and the other part delayed by the light phase will first be guided along the profile of the slot, accelerating as it moves to the periphery of the disk and carries the flows from the other layers. These accelerated streams then fall on the device 14, which are fixedly fixed on the iperiperium of the disk 12.

The presence of the cruciformly arranged perforated and experimentally intensive devices intensifies the process due to additional interleaving, reducing the longitudinal displacement and strengthening the transverse displacement of the light and heavy phases.

Performing a cruciform |: 1And mixing devices perforated, for example, in the form of frames 15 with a wire mesh 16, significantly reduces the energy required for shifting. The cross shape of the devices changes the current profile of the layers of the light and the same; 1st phase in both vertical and horizontal slots.

nepeMeujHBaK) devices for the assembly and disassembly of the device are pivotally connected to the side surface of the dipping disk. Depending on the speed of rotation, the mixing devices may take positions from vertical to horizontal. For the cost of monolithic mixing costs, especially in that case, when the liquids have a large viscosity, the displacement devices are purposefully performed with a triangular profile narrowing towards the periphery.

The light phase, moving with the countercurrent heavy phase, rises up, part of it slips through the epiral slot 5 in the dispersing disk, and the other part (significantly larger but volume) shifts with the heavy phase, changing the flow profile and swirling under the action of perforated moving devices.

The proposed extractor significantly increases the productivity of the apparatus due to the intensification of transverse displacement and an increase in the contact surface of the phases.
