Definitions

  • the invention relates to the design of package nozzles for heat and mass transfer column apparatuses used for the implementation of absorption, desorption, rectification, wet dust collection in the chemical, petrochemical, metallurgical, energy and other related industries.
  • the heat and mass transfer process is carried out not by organizing intensive mixing of the interacting phases, but by increasing the surface area of the contact phase.
  • porous, mesh and the like materials with a large specific surface are used.
  • the apparatuses with a bulk nozzle (granular, chordate) used for a long time in the industry were improved and equipped with more advanced types of nozzles, such as Pall rings, Intallox, Berl saddles and other types.
  • Advanced nozzles have led to an increase interfacial surface in a unit of occupied volume, but they were not devoid of drawbacks characteristic of packed wet scrubbers, and differing, first of all, by a low velocity of the gas flow along the free section of the apparatus - 1-4, 5 m / s. and a small mass transfer surface, since at these speeds a film flow of the liquid is observed.
  • More developed contact devices in the column apparatus are plates.
  • the designs of plates developed and used in the industry are very diverse, some of them are standardized.
  • the choice of the type of plate, for example, during rectification, is determined by the type of mixture, column capacity, requirements for the degree of rectification, the quality of the separated components (fractions), working pressure in the column, etc.
  • Plate columns are used, as a rule, in large-scale production.
  • the intensification of the heat and mass transfer process between the interacting liquid and vapor phases is ensured mainly due to the maximum possible increase in the relative velocity of the phases during the bubbling of the gas or vapor phase through the liquid layer.
  • the maximum intensity of the process is achieved with the turbulization of a two-phase system, however, in traditional plate designs, it is not possible to achieve a turbulent flow due to restrictions on the velocity of the vapor phase due to the "flooding" of the column and unacceptably high pressure losses in the contact devices).
  • the average level of efficiency of the plates used at present is 50-70%.
  • the modern stage in the development of contact devices is the creation of batch nozzles, characterized by a developed interphase contact surface of the phases, a higher speed of movement of the gaseous phase and a more stable countercurrent mode of operation, in comparison with other types of nozzles.
  • Known batch vortex nozzle for heat and mass transfer apparatus (RF patent N ° 2205063 from 05.27.2003), which by technical essence is closest to the claimed one.
  • This nozzle is a set of identical rectangular cells connected to each other in a single package, while the walls of each cell are displaced vertically relative to each other, blocking the frontal slit at the entrance to the cell due to inwardly curved ends forming a swirler, and at the outlet of the gas stream from the cell endings of both walls also made curved into the cell, blocking the frontal slit and forming a second swirler.
  • the invention does not significantly improve the efficiency of heat and mass transfer in apparatuses in gas-liquid, vapor-liquid systems due to the swirling of the gas-liquid flow around only the horizontal axis in each cell, the intensive formation and effective separation of droplets of the liquid phase in each cell and the turbulent gas flow - vapor-liquid mixture.
  • a batch vortex nozzle for column mass transfer apparatuses consisting of many identical rectangular cells connected to each other in a single package due to its manufacturing technology, while the opposite walls of each cell are offset vertically relative to each other, blocking the frontal slit at the entrance to the cell due to elongated, bent inward endings forming an optimal form of a swirl, and at the exit of the gas stream from the cell, the ends of both walls are made elongated and bent three cells, blocking the output frontal slit and forming another flow swirl at the outlet of the cell, while in contrast to the well-known patent, the output frontal slit of each cell is located 90 ° relative to the entrance slit, which allows you to create a swirl of the flows not only relative to the horizontal axis, but also relative to the vertical axis.
  • the surface of each cell is completely or partially covered with regular roughness and / or perforation of any shape of the holes.
  • the cells in the package when viewed from above and from below, are assembled in such a way that the frontal slots of each cell and four adjacent perimeter cells, which are swirlers, are mutually perpendicular, and the vortex flows from the adjacent output frontal slots of each cell are directed in different directions, which allows quickly and efficiently evenly distribute the gas-liquid system along the diameter of the apparatus.
  • the batch nozzle has a high capacity for liquid and gas phases, low hydraulic resistance, high values of heat and mass transfer coefficients, uniform distribution of liquid and gaseous flows over the diameter of the apparatus, high separation ability in the liquid phase, compactness and manufacturability.
  • the novelty of the described packet nozzle is a developed curved surface, the main purpose of which is to intensify the mass transfer process due to the presence of several vortex flows created by specially created swirlers gas-liquid flows at the inlet and outlet of the cell due to the rapid formation and separation of a large number of drops on the cell walls, the bottom swirl being mutually perpendicular to the upper swirl.
  • the nozzle is designed for heat and mass transfer apparatuses used for the processes of absorption, desorption, separation of multicomponent mixtures (rectification), wet dust collection in the chemical, petrochemical, energy, metallurgical and other related industries.
  • the proposed batch vortex nozzle works as follows. In the operating mode, with countercurrent movement of phases: gas or vapor-liquid with turbulent and swirling motion of gas or steam, intensive formation and simultaneous separation of droplets of the liquid phase on the cell walls occurs, as a result of which a developed phase contact surface is formed, high coefficients are realized heat and mass transfer and at the same time the hydraulic resistance of each cell is reduced due to faster formation and deposition of droplets on the walls due to the fact that the gas swirls a or vapor-liquid flow is carried out not only relative to the horizontal axis, but also relative to the vertical axis in connection with the perpendicular arrangement of the input and output swirls of each cell.
  • the range of working speeds in the gas phase is 2-IZ m / s, the range of working densities of irrigation is 20-M 00 m3 / (m2-h).
  • the hydraulic resistance of the 1st layer of a high-intensity packet vortex nozzle is less than 100 Pa.
  • the fraction of the free section is 0.7-Yu, 99.
  • FIG. 1 shows a comparison of hydraulic resistance and the number of transfer units per meter a column apparatus for four types of contact devices (nozzles) - traditional - Rashig rings and fluidized nozzles (PSON), one of the most effective nozzle contact devices - nozzles of the Sulzer company (using Mellapak 250. X as an example) and the modified batch vortex nozzle we offer (PVN).

  • NT 40m 3 / m 2 h; Row 4 - 250.
  • FIG. Figure 3 shows a batch vortex nozzle with a diameter of 300 mm.
  • the proposed batch vortex nozzle also has ease of scaling in the transition to larger diameter devices, since in the transition from a small diameter to a larger one, only the number of vortex cells increases.
  • the nozzle has a good redistributing ability of the liquid phase over the cross section of the apparatus even when the latter is fed to one point.
  • the presented sample batch vortex nozzle is made of structural material - 08X18H10T, the thickness of the sheet material is 0.3-0.5 mm.
