Definitions

  • the present invention relates to a device making it possible to divide a stream of primary liquid into several secondary streams whose flow rates are predetermined fractions of the flow rate of the primary stream.
  • the object of the invention is to propose a distributor device making it possible to divide a stream of primary liquid into several secondary streams, and to maintain the flow rates of the primary stream and the secondary streams in predetermined ratios, when the flow rate of the primary stream varies.
  • a device for dividing a stream of primary liquid into several secondary streams whose flow rates are predetermined fractions of the flow rate of the primary stream characterized in that it comprises a main chamber receiving the stream of primary liquid, and several secondary chambers adjoining the main chamber, the number of which is equal to that of the secondary currents, in that each secondary chamber is separated from the main chamber by a partition in which is cut at least one vertically elongated opening and whose width increases gradually from bottom to top, in that the bottom of all the openings is at the same level, all the openings having the same general shape and their width, at a given level, being all the greater as the fraction of the total flow which passes through them is more important, and in that each secondary chamber is provided with an outlet for a secondary current.
  • the partitions separating the secondary chambers from the main chamber are removable, so that they can be replaced by other partitions having different openings, and thus modify the distribution of the primary current between the different outputs of the secondary chambers.
  • At least one of the other replacement partitions is then a solid partition in order to reduce the number of secondary currents.
  • the partitions separating the secondary chambers from the main chamber are, at least in part, provided with means for adjusting the useful section of their respective openings.
  • Each adjustment means advantageously comprises a rotary shutter capable of partially closing the cooperating opening.
  • the device is advantageously constituted by a container divided by partitions, into a main chamber and several secondary chambers.
  • the partition openings are formed by V-shaped notches.
  • the container is preferably cylindrical, with a horizontal axis, and has in its lower part an inlet situated substantially at mid-length and one or more outlets at each of its ends.
  • the two transverse partitions in which the V-shaped notches are cut are then placed between the inlet and the two outlets.
  • angles at the top of these notches are chosen according to the desired distribution of the inlet flow between the two outlets.
  • longitudinal partitions are provided to form between the end wall of the container and the adjacent transverse partition, as many secondary chambers as there are outlets, each secondary chamber comprising an outlet and communicating with the main chamber by a notch.
  • Means are provided for maintaining the pressure in the container at a predetermined value.
  • Vertical flat sheets are advantageously arranged in the main chamber, parallel to the axis of the container, and spaced transversely from each other, in order to keep the surface of the liquid flat.
  • Figure 1 is an elevational sectional view of the device.
  • Figure 2 is a section along line A-A of Figure 1.
  • Figure 3 is a section along line B-B of Figure 1.
  • Figure 4 is a section along line C-C of Figure 1.
  • the mark 1 generally designates a cylindrical container with a horizontal axis XX having, in its central part, a main chamber 2 supplied with a stream of liquid at its lower part by means of the tube 3 located substantially at the mid-length of the container 1.
  • a main chamber 2 supplied with a stream of liquid at its lower part by means of the tube 3 located substantially at the mid-length of the container 1.
  • vertical flat sheets such as 4
  • These sheets are transversely spaced and arranged parallel to the axis XX of the container 1. They are made integral with the walls of the latter by means of through rods, such as 5.
  • FIG. 1 On the right-hand side of FIG. 1, there is shown a first secondary chamber 6 adjoining the chamber 2 from which it is separated by a transverse partition 7.
  • the chambers 2 and 6 communicate with each other by a notch 8 with a V section practiced in the partition 7.
  • the liquid admitted into the chamber 6 through the notch 8 leaves said chamber through a tube 9.
  • the end of the container 1 is provided with a viewing window 10 which makes it possible to observe the flow inside the chamber 6.
  • FIG. 1 On the left-hand side of FIG. 1, two other secondary chambers 11 'and 11 "are shown adjoining the chamber 2 from which they are separated by a transverse partition 12.
  • the chambers 11' and 11" are separated from one other by a longitudinal partition 13.
  • the main chamber 2 communicates with the secondary chambers 11 ′ and 11 ′′ by notches, respectively 14 ′ and 14 ′′, with a V section formed in the partition 12, symmetrically on either side of the partition 13.
  • the liquid admitted into the chambers 11 'and 11 through the notches 14' and 14", leaves said chambers by two pipes, respectively 15 'and 15 ".
  • the end of the container 1 is provided with a sight glass 16 which makes it possible to observe the flow inside the chambers 11 'and 11 "in a manner analogous to the arrangement described with reference to the opposite end.
  • the partition 7 can be provided with a flap 17 in the form of a circular sector, able to pivot around an axis located at the tip of the V formed by the notch 8 so as to more or less close the latter.
  • the partition 12 can be fitted with flaps 18 ′ and 18 ′′ of the same shape as the previous one, capable of pivoting around axes located at the tip of the V formed by the notches 14 ′ and 14 ′′, respectively, so as to seal more or less these notches.
  • the displacement of each flap can be carried out by any means, for example a screw, controllable from the outside. This arrangement is particularly advantageous for modifying the distribution of the outlet flow between the pipes 9, 15 'and 15 ". It is necessary to place the point of the notches 8, 14' and 14" at the same level. At a given level, the width of said notches is greater the greater the fraction of the total flow which passes through them.
  • the number of secondary bedrooms may be different from three.
  • each secondary chamber can provide on the side of each secondary chamber, a transverse partition made up of several removable elements, each elementary partition comprising a single indentation. easily replace one elementary partition with another having a notch with a different angle. It is also possible to provide at least one full elementary partition if it is desired to limit the number of outlets. output on demand.
  • the container instead of being cylindrical, being of parallelepiped shape, open at its upper part.
  • the liquid inlet can then be arranged above the container.
  • the partitions do not necessarily reach the level of the upper edge of the container.
  • the partitions can then be arranged along the same side or along two opposite sides.
  • main chamber of cylindrical shape with a vertical axis, and peripheral secondary chambers arranged radially around the main chamber.
  • the wall of the latter is then provided with notches, at the rate of a notch by adjoining secondary chamber.
  • the liquid supply can be carried out from the top or from the bottom of the cylinder and the outlets are arranged radially outwards, that is to say on the side opposite to the main chamber.
  • means can advantageously be provided to maintain the pressure in the container at a predetermined constant value.
