Definitions

  • the invention relates to a device for the evacuation towards the atmosphere of a gaseous fluid from a discharge pipe.
  • the invention relates particularly to a device for the evacuation to the atmosphere of stale air extracted from premises, such as premises housing, administrative premises, industrial premises or other.
  • the invention relates especially to a device intended to be fixed in protrusion with respect to an external surface, such as a roof surface, for ensure the evacuation of a flow of air with a determined speed, according to a substantially vertical direction.
  • the chamber houses a element, called collection, arranged axially to collect and evacuate controlled way the rainwater that enters the room through said second opening.
  • the collection element consists of a single receptacle (DE 44 19 604) or a network of a plurality of small receptacles (JP 60 129 522), it generally extends transversely to the longitudinal axis of the device on a section of extent substantially greater than the cross section of the second opening.
  • the transverse dimensions of the chamber at the level of said collection element are greater than the transverse dimensions of the upstream chamber and downstream of said collection element, so as to compensate for the loss of section induced by the presence of this collection element.
  • the wall of the chamber is relatively thin and the shape external device is very close to its inner shape.
  • This type of form does not satisfy, in particular, architects who preferentially look for cylindrical shapes of cross-section circular or polygonal.
  • a solution to the problem posed by the external form of known devices would consist in constituting a cylindrical dressing around the evacuation device.
  • the state of the art also includes devices absolutely cylindrical, for example DE 41 19 971, constituted by a section pipe in which a spiral collecting element extends.
  • a result that the invention aims to obtain is a device of the aforementioned type, which while ensuring the evacuation vertical flow of gaseous fluid with adequate speed, has a shape substantially, but not exclusively, cylindrical or slightly conical and, is of comparable manufacturing cost, or even lower, to devices of the state of the art whose form and / or effectiveness have been criticized.
  • This device 1 comprises at least one chamber 6 defined by a inner face 7 of a tubular wall 8 which, in the position of use present a longitudinal axis 9 substantially vertical, is intended to be crossed by the flow of gaseous fluid 4 along its longitudinal axis 9.
  • tubular wall 8 of the device 1 has a section circular cross-section and a cylindrical form of revolution, but this is not not limiting for the invention.
  • the invention adapts perfectly to the construction of devices of the aforementioned type, whose cross section is polygonal, for example, square.
  • the invention adapts perfectly to the construction of devices of the aforementioned type which are not absolutely cylindrical.
  • the device 1 At its lower part the device 1 comprises a connection means 50 with the evacuation pipe 5 to which it must be connected.
  • this link means 50 consists of a range assembly with the end of the exhaust pipe 5 to which it must to be connected.
  • the first opening 10 of the device 1 is located in the extension of this bore.
  • the chamber 6 houses an element 12, called collection, situated axially for collecting and discharging in a controlled manner a liquid fluid 13, such as water of rain, entering the chamber 6, by gravity, by said second opening 11.
  • a liquid fluid 13 such as water of rain
  • liquid fluid 13 has been represented by a plurality circles associated with reference 13.
  • this collection element 12 consists of advantageously in a hollow part of conical or hemispherical shape which turns its concavity towards the top of the device so as to collect water falling in said device 1.
  • the hollow part is provided with of an evacuation pipe, for example, through the tubular wall 8 of the device 1.
  • the second speed V2 is substantially equal to two times the first speed V1.
  • the sections can have a solid wall, as is shown, or a hollow wall, or even a hollow wall filled with a thermally and / or acoustically insulating material.
  • the device 1 comprises a member 17 for guiding drops of liquid fluid 13 towards the collecting element 12, such as a flange 17 projecting from inside the second section 15.
  • the section cross-section of chamber 6 is inscribed in the cross-section of the collection element 12 and centered on the latter.
  • the algebraic value of the section transverse of the second opening 11 of the device 1 is greater than the algebraic value of the largest cross section of the second controlled passage 151 of the flow between the second section 15 and the third section 16 but lower than the algebraic value of the cross section of the first opening 10 (inlet opening) of the device 1.
  • a evacuation device which while ensuring the evacuation of a flow gaseous with a desired speed, has a substantially external shape, but nonlimiting, cylindrical or slightly conical and, is of a cost of Comparable or less than comparable manufacture to the devices of the state of the art whose form and / or effectiveness have been criticized.
  • the outer diameter is two hundred and six millimeters.
  • the diameter of the first opening is six hundred millimeters, a piece of the diameter of which is four hundred and forty millimeters, respecting the conditions set out above, a person skilled in the art can build a device that with an airflow of six thousand three hundred cubic meters per hour at the entrance allows to admit a flow of air with a first speed of 6.2 meters per second (six decimal two meters per second) and eject this stream of air with a speed of 8.9 meters per second (eight point nine meters second).
  • the outer diameter is six hundred and six millimeters.
  • first section 14 of the device 1 comprises, at least at the level of the connecting means 50 with the driving 5, at least one channel arranged to ensure controlled evacuation fluid fluid 13 located on the inner cylindrical surface 144 of said first section 14, this evacuation being carried out of the device 1.
  • the device 1 comprises a means of connection 50 with the evacuation pipe 5 to which it must be connected and this connecting means 50 consists of an assembly surface with the end of the evacuation pipe 5 to which it must be connected.
  • the linkage means 50 of the device 1 with the exhaust pipe 5 to which it is to be connected consists in an assembly span by interlocking on an outer surface of the end of said discharge pipe 5 and, secondly, this scope comprises a plurality of channels each of which is constituted so as to evacuate the liquid fluid 13 between the wall 142 of the first section 14 (first wall element 142) and the outer surface of the exhaust pipe 5 which receives the device 1.
  • the connecting means 50 may also comprise a joint, but the skilled person is able to provide such an element without having to do proof of invention.
