Definitions

  • This invention relates to bubbling valves of the type utilized in the trays of gaseous-phase and liquid-phase exchange apparatus.
  • these valves With these valves the transfer conditions, in comparison with conventional systems such as cylindrical or rectangular caps, or perforated trays, are improved considerably.
  • these valves are easily manufactured by punching and stamping, they constitute an economical proposition.
  • valves are frequently objectionable because they are scarcely adapted to properly divide the gas or vapour in the liquid mass, and furthermore they are attended by a considerable degree of priming whereby the trays must be spaced to a substantial extent from each other. Moreover, the valves remain locked in their upper or open position, thus causing an imperfect operation of the tray when working conditions are restored.
  • slots formed in the valve according to an arrangement constituting an essential feature of this invention provide a leakage path through these valve slots, thus providing a better equilibrium and preventing the valve from jamming during its vertical translation in the tray aperture, which is a frequent occurrence in other types of valves.
  • the valve consists of a disk in which slots disposed along one or a plurality of circles concentric to the disk axis are formed. If these slots are disposed on a plurality of concentric circles their number may vary, but preferably the different concentric circles will have the same number of slots and these slots will be distributed in staggered relationship between adjacent circles. The number of these slots may advantageously be three per circle.
  • the concentric series of slots lie on a plane somewhat raised with respect to the valve edge and the slots themselves lie at different levels, the differences in level being of the order of 1 to 5 mm.
  • This invention is also concerned with exchange trays equipped with bubbling valves of the type broadly set forth hereinabove which are disposed on the tray according to a triangular, square or rectangular mesh pattern.
  • FIGURE 1 illustrates in side elevational and partsectional view the bubbling valve in its closed position
  • FIGURE 2 is a plane view of the valve shown in FIGURE 1;
  • FIGURE 3 is a perspective view of the same valve
  • FIGURE 4 is a cross-sectional view of the valve
  • FIGURE 5 is a diagram showing a curve plotting the loss of pressure as a function of the velocity of the gas flowing through the valve
  • FIGURE 6 is another diagram showing the curve plottingthe valve efficiency as a function of the gas flow velocity
  • FIGURES 7, 8 and 9 are plane views showing various patterns of the apertures formed in-the exchange trays, each aperture being equipped with a valve, and
  • FIGURE 10 is a fragmentary elevational and sectional view of an exchange apparatus equipped with trays comprising bubbling valves according to this invention.
  • the valve consists of a disk 1 of relatively reduced thickness, for example 1 to 3 mm., in which slots 2 and 2a are punched along two concentric circles disposed at different levels, said slots being arranged in staggered relationship from one circle to another.
  • the valve is fitted on the tray 3 and guided by lugs 4 extending through a circular aperture 5 formed in the tray. In its upper or open position the valve has its stroke limited by lateral extensions 6 of said lugs.
  • the permissible stroke a-b of these disks may be of the order of 5 to 20 mm.
  • the bubbling valve according to this invention operates as follows:
  • the tray utilizing these valves is disposed like a conventional exchange tray in that the stream of liquid pouring from the overflow-chute of the upper tray flows through the set of valves and overflows into the chute leading to the underlying tray.
  • These trays may comprise one or more liquid circulation paths.
  • the trays may be held in the columns through any suitable and known means.
  • the pressure drop increm entKF IGURE. 5 is considerably lower than that observed with conventional apparatus.
  • the pressure drop A varies from 30 mm. of water column to 50 mm. of water per tray when the gas speed v changes from 0.3 to 2 m./s. in a tray tested with air and water, this speed v being measured under empty column shaft conditions.
  • the efiiciency E (FIGURE 6) is increased due to the nearly complete utilization of the tray surface for bubbling gas through the liquid and may attain or even in certain cases exceed 100% of the theoretical efficiency expressed according to the Murphee method. For a given gas output the efficiency is improved notably by the reduction in the priming.
  • This priming reduction permits on the other hand of reducing the relative spacing of the trays and therefore the height of the columns as much as 20% of the height of columns equipped wih conventional bell or valve trays having a different geometrical arrangement.
  • the range'of operation under satisfactory conditions of efiiciency is increased as the valves are not prone to jam in their upper position due to the self-centering action caused by the gaseous flow through the slots 2 and 2a.
  • FIGURE 7 illustrates an exchange tray 3 comprising holes 5 disposed according to a square-mesh pattern, each hole being equipped with a valve.
  • FIGURE 8 illustrates a modified form of embodiment wherein the holes are disposed according to a rectangularmesh pattern.
  • FIGURE 9 shows a modified structure wherein the holes are disposed according to a triangular-mesh pattern.
  • FIGURE 10 illustrates in section a distillation column 10 comprising trays 3 equipped with valves of the abovedescribed type.
  • the liquid delivered from the chute 12 of the upper tray 3 fiows through the valve assembly and overflows into the next chute 13 from which it is directed towards the next tray.
  • the arrows show the direction of circulation of the gas or vapour flowing through the valves and bubbling through the liquid.
  • a bubbling valve for a gas liquid contact apparatus '4 consisting. of a relatively thin disk formed with a plurality of rectilinear slots disposed tangentially on a plurality of imaginary circles concentric to said disk, the slots on a first circle being spaced radially inward from the slots on a second circle and the slots on a given cricle being staggered with respect to slots on adjacent circles, said disk being adapted to reduced primingand providing a selfcentering effect.
  • valve of claim 1 wherein the valve is provided with depending guide lugs adapted to extend through a corresponding valve aperture in a tray of the apparatus, said guide lugs having lateral extensions for limiting the permissible vertical stroke of the valve.
  • a gas liquid exchange apparatus equipped with trays having a bubbling valve consisting of a relatively thin disk formed with slots disposed tangentially on a plurality of circles concentric to said disk, said slots being disposed at different levels, each circle comprises three slots the slots of one circle being shifted inrelation to those of the adjacent circles, said disk being also formed with depending guide lugs adapted to extend through a corresponding valve aperture formed in the tray of the apparatus, said lugs being formed with lateral extensions for limiting the permissible vertical strokes of the valve.
