Nozzle for vibration mass-transfer apparatus
FIELD: machine building.
SUBSTANCE: nozzle is stock with rigidly secured on it trays, perforated by holes having cylindrical or cone shape. Along periphery of each tray the flanging is rigidly secured at both sides, at that gap between the wall and tray edge is 2 mm maximum.
EFFECT: extended range of stable operation and increased efficiency of the performed operations in the vibration apparatus.
The invention relates to the design of mass-exchange apparatus for the system of liquid - solid and can be used in food, chemical, chemical-pharmaceutical and other industries that use the processes of extraction.
Known the perforated nozzle  for column vibrating mass transfer apparatuses comprising a set of disks, each of which has a cut along the chord (cut-off up to 15% of the area of the disk) and a flange around the perimeter of the disk. The discs in the machine going so that the adjacent sections of the discs were on opposite sides, and the flanging disc is directed against the direction of motion of the dispersed phase, i.e. down if the disperse phase is easier solid, or up, if the dispersed phase is heavier.
If the dispersed phase is heavier than the solid, particulate phase, moving from top to bottom, going on drives nozzles in spaces that are limited by the drives and their flanging, it occurs at retention and cross-flow stream of the continuous phase.
The disadvantage of this design when working in the system solid - liquid is free flowing particles of the solid phase from one plate to another resulting in slowing down the update rate of the surface of contact of phases and, as a result, decreases the efficiency of mass transfer, if the difference between PL�of Testa minor or the solid phase particles of small size, then we have the carryover from the apparatus, with the flow of the solid phase, thereby decreasing the duration of their treatment.
Closest to the proposed invention to the technical essence and the achieved result is a nozzle , which is a stem rigidly mounted thereon perforated plates provided on the periphery of the sides, pointing in the direction opposite to the motion of the phases, i.e., downward, as both phases are moving from bottom to top.
The disadvantages of this technical solution are: a certain sensitivity of the apparatus to the ratio of phases and their density, for example of low-flow solid phase she does not have time to accumulate in the space above the plate, and at a sufficiently large flow rate of the solid phase it accumulates excessively under it, which causes it to freeze solid phase in the column apparatus; such regimes do not effectively work.
The objective of the proposed technical solution is the extension of the range of stable operation, improve the efficiency of existing processes in a vibratory machine.
The technical result is achieved in that the plates of which the nozzle is installed in the casing with a gap between the outer wall and a plate diameter of 2 mm, and on the periphery have a flange rigidly fixed p� both sides of the plate. The height of each side flanging provides for the formation of directed jets of higher pressure on both sides of the plate.
Fig. 1 shows a diagram of vibrating nozzles with three perforated plates. The attachment contains: stem 1; a perforated plate 2 having a flange 3. The height of the flange above and below the plate is equal to h1and h2accordingly, the total height of the flanging is h1+h2+δ, where δ is the thickness of the perforated plates.
The work of the vibration of the nozzle is as follows. When oscillation of the nozzle in the working volume of the apparatus is the formation of the alternating movement of the treated system: liquid - solid. This ensures a high rate of formation of short waves and cavitation vortices by passing the liquid through the holes of the perforated plate 2. The rate of formation of such waves and the resulting wave energy are heavily dependent on the differential pressure on both sides of the perforated plate 2. It is therefore necessary to create a greater hydraulic resistance to the passage of the contacting phases in the gap between the wall of the device and the periphery of the plate. To do this, around the perimeter of the plate is rigidly secured to the flange 3, distributed on both sides of the plate, the height of each Board is determined by the structural�-mechanical, physico-chemical properties of the processing system and regime parameters (amplitude and frequency) and is set empirically.
Placement flanging on both sides of the plate will provide the intensification of mass transfer process through the creation of a hydrodynamic regime, characterized by high-speed update of the contact surface phases jets formed during the passage of the treated system through the holes of the perforated plates.
Clearance between the housing wall and the outer diameter of the plates is not more than 2 mm will significantly increase the flow resistance in the gap, which in turn increases the differential pressure on both sides of the plate, thereby increasing the energy of the jet and creating an active hydrodynamic regime, characterized by a high refresh rate of the surface of contact of phases and high intensity of mass transfer. To increase the process differential pressure may reduce the gap, but it increases the likelihood of clogging of the fragments of the solid phase, which in turn could lead to increased costs energy to create the reciprocating motion of the nozzle and reduce the stability of operation of the machine.
The proposed technical solution will allow to create conditions under which the differential pressure� on both sides of the perforated plates will be higher than using unidirectional flanging. Note that the use of unidirectional flanging the same total height will lead to the formation of the hydrodynamic regime, in which the formation of the jets will be less than the period of oscillation of a vibrating nozzle. Whereby particles of solid and liquid phases will move in parallel relative to each other without mutual movement, which slows down the refresh rate of the surface of contact of phases. Clearance between the housing wall and the outer diameter of the plates is not more than 2 mm also contributes to creating the desired pressure differential on both sides of the plate.
The increase in energy of the jets will expand the load range of the device in the solid phase, since it will decrease the likelihood of accumulation of the solid phase on both sides of the perforated plate.
The positive effect of the proposed technical solution is to increase the range of stable operation, improve the productivity and efficiency of the processes in a vibratory machine.

SUBSTANCE: invention relates to cleaning of fluids and can be used at absorption or desorption column. Device comprises mass exchanger containing volatile fluid and poor-volatile fluid. Mass exchanger includes structure bed. The latter includes first layer (10) and second layer (100). Bed first layer (10) contacts with second bed (100) via spacing elements (24, 34, 44, 134, 144). The latter make the component of the bed first or second layer (10, 100) and are composed of bridges. Said elements (33, 43, 133, 143) confine open channels 12, 14, 16, 112, 114, 116. First bed layer (10) and second layer (100) feature wavy profile making said open channels (12, 14, 16, 112, 114, 116). Method of cleaning includes the feed of poor-volatile fluid into mass exchanger and its distribution over common surface. Beside said process comprises the feed of volatile fluid into mass exchanger and its distribution at gas inlet over the common surface. Volatile fluid flows in counter stream with fluid. Then, volatile fluid is collected at the bed fluid exit. Open channels of the bed first layer cross the second layer channels of the bed. Volatile fluid flows in said channels from fluid inlet to outlet. Poor-volatile fluid envelops volatile fluid to flow in the walls of channels. Therefore, mass exchange is increased between volatile and poor-volatile fluids via mass exchange surface composed by said channels.
EFFECT: decreased drop in head, higher separation capacity of structured bed.
