Definitions

  • the invention relates to a supply system, in particular for toxic and combustible Gases, with at least one storage container which contains the gas and with a sampling line and an absorber is connected.
  • Bottle bundles which consist of individual by means of a brazed, high pressure tested Bottles connected to the collecting line are made with an extraction line connected, which directs the fluorine to the places where it is needed.
  • extraction line connected to the places where it is needed.
  • Several bundles of bottles are regularly used to ensure gas supply connected to the sampling line via a switchover device. When the gas pressure of a bottle bundle comes to an end, the bottle bundle becomes switched off from the sampling line via the switchover device and a full one Bottle bundle switched on to the sampling line.
  • a Absorber provided, which is connected to the connecting lines of the bottle bundle is and thus that in the connecting lines or the bottle bundle residual gas can take up.
  • the absorber can only neutralize a certain amount of gas per unit of time, may the pressure of the in the connecting lines or if necessary residual gas in the bottle bundle when the absorber is switched on the connecting lines must not be too large, otherwise the ones supplied to the absorber The amount of gas would be too large, with the result that part of the gas would not would be neutralized and enter the environment as a toxic or flammable substance would.
  • a pressure reducer is arranged between the storage containers and the absorber.
  • the pressure reducer advantageously ensures that only a certain amount of gas is passed to the absorber.
  • the amount of gas can be determined by setting the back pressure, i.e. the pressure on the side of the absorber. With a larger line leading to the absorber, a lower back pressure must be set than with smaller connecting lines. For example, if the line diameter of the pipeline leading to the absorber is 12 mm with a wall thickness of 1 mm, the back pressure for an absorber with an F 2 absorption capacity of 3 g F 2 / sec. Air should be set to 3 bar, because then only 2.5 g F 2 / sec.
  • the gas pressure reducer is set to a back pressure of less than 3 bar in a supply system according to the invention, the F 2 absorber can absorb any residual gas amount from each bundle if the bundle valve is leaking.
  • the pressure reducer is therefore advantageously designed for a pre-pressure of 200 bar and an adjustable back pressure of 0 to 10 bar.
  • a vacuum pump is provided, which is located in the absorber line and the connecting lines Gas sucks through the absorber. It is particularly advantageous if the Pressure reducer can be sucked through from the vacuum side. This can ensure be that after the bundle changeover the residual gas from the line between the absorber and the switching station and between the storage container and the switching station or from the reservoir itself is sucked. This means that after loosening the reservoir from the Connection lines no residual gas flows out of the line. This is particularly so In the case of supply systems for fluorine, this is a great advantage, since fluorine no longer comes from the Lines escapes and poisoned people through the formation of hydrogen fluoride or Bottle bundles corrode from the inside due to leaky bottle valves be destroyed.
  • FIG. A supply system according to the invention It shows the only FIG. A supply system according to the invention.
  • a supply system there are two bundles of bottles 1 and 2 connected to a removal line 3 via a switching device 10.
  • the bundles of bottles 1, 2 are each via a flexible line 1a, 2a with permanently installed Connection lines 1b, 2b connected.
  • connection lines 1b, 2b are to the extraction line 3 towards the first pressure reducer 8, 9.
  • the pressure reducer 8, 9 the gas pressure prevailing in the cylinder bundles 1, 2 is reduced to the operating pressure.
  • the connecting lines 1b, 2b there are between bottle bundles 1, 2 and pressure reducer 8, 9 pressure switch 13, 14, which in the connecting lines 1b, 2b monitor the prevailing gas pressure.
  • the connecting lines 1b, 2b are further connected to absorber lines 4, 5, which each have an absorber, not shown, with the connecting lines 1b, 2b and thus connect to the bundles of bottles 1, 2 via the first lines 1a, 2a.
  • Second pressure reducers 6, 7 are connected in the absorber lines 4, 5.
  • the second pressure reducers 6, 7 are for a pre-pressure of 200 bar and an adjustable Back pressure designed from 0 to 10 bar.
  • solenoid valves 11, 12, which close normally before the absorber, are switched, which the absorbers from the absorber lines 4, 5 and thus from the Can cut lines 1a, 2a, 1b, 2b.
  • the pressure switch 13 shown on the left reports that the Pressure of the bottle bundle is 5 bar, it sends a signal to the switching station 10, which then separates the supply line 1b from the extraction line 3 and the supply line 2b connects to the extraction line 3.
  • the supply line 1b is closed in a pressure-tight manner after the changeover in the changeover station 10.
  • the state is shown in which the right bottle bundle 2 with the extraction line 3 connected and the supply line 1b in the switching station 10 is closed pressure-tight.
  • the pressure in the supply line is 1b in the selected one Example 5 bar.
  • the solenoid valve 11 is opened. That is in the connecting line 1b and the supply line 1a residual gas is via the absorber line 4th fed to the absorber.
  • the second pressure reducer 6 the pressure at one Line diameter of the absorber line 4 of 12 mm with a wall thickness reduced from 1 mm to, for example, 3 bar in the absorber line 4. It is therefore ensures that only as much residual gas is supplied to the absorber per unit of time, how he can neutralize.
  • a vacuum pump not shown, which is located in the pipe network residual gas sucks through the absorber.
  • the second pressure reducer is for this purpose 6, 7 designed so that they can be sucked through from the back pressure side. That means, that even if there is no more pressure on the pre-pressure side, gas can flow through the pressure reducer if the pressure on the back pressure side is less than on the pre-printed page.
