Definitions

  • the invention relates to a device for sudden discharge of air.
  • relief devices also called air gun.
  • the principle of these devices is to release suddenly a quantity of air so as to create a kind of deflagration that will remove the accumulation of material that accumulates during the manufacturing process.
  • such a device comprises a body housing a piston constituting a shutter disposed between a capacitor and an outlet pipe.
  • This outlet pipe is more or less long but, generally, for manufacturing and / or wear problems, this outlet pipe comprises a first part integral with the body of the discharge device and a second part or accessory intended to come extend the first part.
  • the discharge device being located outside the oven, this second part allows in particular to cross the wall and to open more or less distance from the inner face of said wall.
  • this second part or accessory also called nozzle
  • this second part or accessory has a constant surface area along its longitudinal axis but often the geometry of this section is variable.
  • the geometric shape of the input of this accessory is circular while the output geometry is eventually flattened to be able to occupy the place of one or more refractory bricks.
  • the volume of the capacity is limited because of the congestion thereof and, in many cases, the air supply pressure of these capacities is limited.
  • the invention proposes to provide a solution to improve the efficiency of these devices for sudden discharge of air.
  • the subject of the invention is a device for sudden discharge of air having the features of the main claim.
  • a device 1 for sudden discharge of air contained in a capacity 2 there is shown a device 1 for sudden discharge of air contained in a capacity 2.
  • the discharge device is mounted, for example, on a wall 9.
  • This sudden discharge device comprises a body 1A or envelope containing a shutter 3 and its seat 3A, which shutter, when moved away from its seat, allows the passage of the air contained in the capacity to an outlet pipe 4.
  • This short outlet pipe is extended by an accessory 5 in the form of a tube mounted coaxial with the axis of the outlet pipe 4.
  • This accessory is fixed on the end of the outlet pipe, by a fastening means 10 such as a flange.
  • This accessory 5 is generally fixed in a wall 9 through which it passes.
  • the air contained in the capacity escapes brutally by releasing, in a brief moment, a large energy causing a deflagration, ie an impact force that can be measured using a force sensor.
  • the area of the section of this tube decreases in the direction F of the air exhaust and then increases, thus forming a convergent section A and then diverging B.
  • the area E of the input of the accessory will be equal to the output area S.
  • the area S of the output of the accessory will be greater than this input area E.
  • the ratio between the section D taken at the level of the section having the smallest surface and the input section E will be greater than or equal to 1/5 but preferably greater than 1/3.
  • the ratio between the section D taken at the section with the smallest area and the section S output will be greater than or equal to 1/5.
  • the distance between the position of the aforementioned section D and the seat on which the shutter is resting will be a maximum of one meter for a pressure up to twelve bars.
  • Tests were carried out with an abrupt air discharge device with an inlet diameter E of 150 mm with a capacity of 100 liters.
  • the force sensor is placed at the end of a tube 500 mm long.
