Definitions

  • the invention relates to a device for flameless pressure relief with a casing, which has an inlet opening for the entry of gases, dust and / or flames into the space enclosed by the casing (4).
  • the devices provided for this purpose extremely efficiently cool the flames that arise in a building or a vessel in the layers of the textile fabrics made of metal threads and thus suffocate them.
  • An overpressure prevailing in the building or the vessel is also reduced via the device. The flames do not come out of the device.
  • Both the Q-Box and the Q-pipe define a space into which the flames can enter and which is delimited by at least one inner layer made of a textile fabric made of metal threads.
  • the area over which the pressure relief can take place is predetermined by the choice of the size of the room.
  • Both the Q-Box and the Q-tube have an outer basket or an outer housing, the or that holds the inner layers of textile fabrics made of metal threads together.
  • the outer basket or the outer housing does not contribute to flameless pressure relief. Struts of the outer basket or the outer housing even reduce the effective area for pressure relief.
  • Another property of the previous constructions is that the shape of the device and also of the inlet opening are predetermined by the outer basket or the outer housing. An adaptation of the device to different spatial conditions at the place of use or to different openings in containers to be relieved etc. is therefore not readily possible.
  • a device for flameless pressure relief which has three coaxially nested tubes in which a pot is arranged coaxially.
  • the pipes and the pot are called cylinders.
  • the tubes and the pot have an inlet opening on a side facing away from a bottom of the pot, through which gases, dust or flames can enter a space delimited by the tubes and the pot. Holes in the tubes and in the pot form outlet openings.
  • the tubes and the pot form a shell.
  • the special thing about the device according to the document DE 20 2014 100 441 U1 is that the pipes and the pot can be pulled out telescopically. This enlarges the space enclosed by the envelope. This enlargement occurs when using the device according to the document DE 20 2014 100 441 U1 flameless pressure relief takes place.
  • the pressure that builds up in the device leads to the telescopic “pulling out” of the casing.
  • the surfaces of the tubes and the pot, in which the outlet openings are provided and through which the gases exit are made of a knitted stainless steel that is supported by a support structure.
  • the invention was based on the problem of making a device for flameless pressure relief simpler and of increasing the effective area for pressure relief.
  • the inlet opening can be connected to an opening of the container to be secured, which opening is closed with a rupture disk.
  • a support frame is provided between the at least one inner layer and the sheath, which gives the sheath and / or the at least one inner layer an additional rigidity, or on the support frame there are several inner layers of a textile fabric made of metal threads, the sheath being the outer Layer wraps the inner layers and the support frame and thus keeps the inner layers in a firm bond with the support frame.
  • the support frame can have an inlet opening for the entry of gases, dust and / or flames into the space enclosed by the shell, the support frame and the inner layers.
  • the cover, the at least one inner layer and / or the support frame can be so flexible that the outer shape can be adapted to the space available at the installation site without the device having to be replaced. It is also possible that the components mentioned are so flexible that they can be adapted to different openings of containers to be secured. For example, the device can be adapted to round or square openings.
  • An outer basket or outer housing is not necessary in a device according to the invention for flameless pressure relief.
  • the function is taken over by a sheath that, like the inner layers, is made of a textile fabric made of metal threads or metal wires.
  • the shell is adapted to the shape of the arrangement of the support frame and / or the inner layers and envelops them. The shell is as close as possible to the outermost inner layer.
  • the support frame is provided so that the inner layers of the textile fabrics do not collapse in a non-use state and the inner ones Layers provide sufficient stability so that the space that can be reached via the inlet openings and is necessary for pressure relief is preserved, the outer shell ensures that the layers do not detach when not in use or in use and fly through the area.
  • the cover is sewn together from several sheets of textile fabrics.
  • the device can have a frame which delimits an inlet opening of the device for the entry of gases, dust and / or flames into the space enclosed by the casing, the inner layers and the support frame.
  • the support frame can be connected to the frame. Then the frame can also limit the entry opening of the support frame.
  • the frame can delimit a round or polygonal, in particular square, hexagonal or octagonal entry opening.
  • the inner layers and / or the cover are connected to the frame.
  • the frame can then also delimit the inlet openings of the inner layers and / or the shell.
  • the frame can have a collar which is suitable and set up for connection to an object to be secured.
  • a collar which is suitable and set up for connection to an object to be secured.
  • bores for screwing the frame - and thus the entire device - to a relief opening of a building or vessel to be protected can be provided in the collar.
  • the shell can have the shape of a spherical section at least in sections. It is also possible that the shell of a device according to the invention is trough-shaped, spherical or oval-shaped.
  • the metal threads and / or the metal braid from which the textile fabrics are made can be stainless steel threads. However, it is within the scope of the invention to also use threads made of other metals or alloys or non-metallic materials.
  • the textile fabrics of different layers can also be made from different metal threads. It is even possible for layers made of a plastic or other non-metallic materials to be provided between the layers of the flat structures made of metal threads. This can also be a textile fabric or a textile body structure. This can then be made from plastic threads or synthetic fibers.
  • the casing of a device according to the invention can be made from a textile fabric made of plastic threads.
  • At least one of the textile fabrics can be a woven fabric, a knitted fabric, a knitted fabric, a braid, a nonwoven fabric or a felt.
  • the inlet opening of a device according to the invention is preferably closed by means of a rupture disk which can be attached to the frame.
  • the first device according to the invention has a frame 1 which includes a rectangular entry opening.
  • the frame 1 has a collar 10 in which holes 11 are provided, via which the frame 1 and thus the entire first device can be attached to a housing or building to be protected.
  • a support frame 2 is attached to the frame 1.
  • the support frame 2 is bent from metal rods 20 which are connected to one another at intersection points 21. With one exception, the bars are curved in a circular arc.
  • a pole is straight. All rods are connected to this straight rod.
  • a shell 4 as the outer layer envelops the inner layers and the support frame 2 and thus holds the inner layers in a firm bond with the support frame 2.
  • the second device according to the invention Figures 8 to 10 corresponds in principle to the first device according to the invention.
  • This shape is the shape of a spherical section. This results in a circular frame 1, which in the case of second device has no collar.
  • Inner layers 3 of textile fabrics made of metal threads are applied to the support frame 2 and are enveloped by an envelope 4 in the form of a spherical section as the outer layer.
  • the space located within the support frame 3 is immediately available for pressure relief. Flames are extinguished through the inner layers and the casing if flames strike the interior of the devices.
