Definitions

  • the invention relates to a device for emptying a pressure vessel with the features specified in the preamble of claim 1.
  • overpressure fuses which are typically used as overpressure fuses rupture discs or pressure relief valves.
  • Rupture disks have the disadvantage that, although they prevent their destruction by bursting the receptacle, but that may be toxic content of the pressure vessel after the decrease in the tank pressure under the critical pressure still flow out of the receptacle. This is not the case when using pressure relief valves.
  • relief valves allow only a relatively slow pressure reduction and soiling and damage can easily cause the pressure relief valves in the occurrence of overpressure in the receptacle does not open or open in another negative case before reaching an unacceptable pressure, so that the potentially dangerous content can escape unintentionally from the receptacle.
  • the present invention has for its object to provide a device for emptying a pressure vessel, which makes it possible to open the pressure vessel described above, without the operating personnel of the device and the environment endangered by escaping substances or by bursting of the pressure vessel.
  • the device according to the invention has a pressure-tight sealable container for receiving the pressure vessel, means for opening the container located in the pressure vessel, means for discharging the container contents and an overpressure protection.
  • the basic idea of the present invention is to open the pressure vessel in a pressure-tight sealable container in order to ensure that the substance in the pressure vessel does not escape to the atmosphere after opening. If the pressure vessel is open, the material then located within the container can be selectively dissipated and disposed of via lines. As a precaution, however, there is an overpressure protection, in the event that due to not completely exclude circumstances when opening the pressure vessel, an overpressure within the container arises, which is above the permissible gas pressure. In order to ensure in this case that not the container is torn apart by the particular sudden increase in pressure, an overpressure protection is provided according to the invention, which optionally also releases short opening large opening cross sections to reliably prevent bursting of the container. It goes without saying that this bursting pressure is sufficiently high, for example, 500 bar, so that the overpressure protection is only active as the last emergency backup, in order to prevent greater damage.
  • a tool is arranged, with which a pressure vessel mounted in the container can be opened.
  • This arrangement allows the opening of the pressure vessel in the pressure-tight sealed interior of the container, so that the contents of the pressure vessel is collected during and after the opening of the container and can not escape into the environment. This is particularly useful when the exact contents of the pressure vessel, which are generally gases and liquids, is unknown, as in any case contamination of the operating personnel and the environment with any hazardous substances stored in the pressure vessel can be prevented ,
  • an analysis of the contents of the container can take place both in the container itself, in which appropriate sensor system is advantageously arranged, which determines the nature of the substance stored in the pressure vessel and preferably outside the container, after discharging the container contents with the container
  • appropriate sensor system is advantageously arranged, which determines the nature of the substance stored in the pressure vessel and preferably outside the container, after discharging the container contents with the container
  • the device means such as lines, pumps, valves and the like.
  • an overpressure safety device is provided on the device.
  • This overpressure protection prevents an overpressure, which can build up after opening the pressure vessel in the container, leading to destruction of the device and endangerment of the operating personnel.
  • the overpressure protection Upon reaching a certain pressure level in the container, the overpressure protection allows a controlled pressure reduction by pressure equalization with the environment.
  • a pressure-compensating structural design of the container is provided according to the invention.
  • the container is formed at least in two parts, wherein at least two parts of the container are clamped together to form the overpressure protection.
  • the tension is designed to firmly connect the separate parts of the container under normal operating conditions, but also allows the parts to diverge upon reaching a critical overpressure and overpressure in the container over the gap formed between the parts can break down a large cross-section.
  • the bracing is preferably designed so that it allows a separation of the parts of the container, but is not destroyed due to its own elasticity, so that the tension returns to a corresponding pressure equalization in the container back to their original state.
  • the parts of the container with tension means, in particular tensioned tie rods. These are arranged between the normal to the contact surface of the container parts spaced ends of the container.
  • the tie rods In addition to the secure cohesion of the parts of the container allow the tie rods with a prevailing in the container inadmissibly high pressure of, for example, more than 500 bar a controlled divergence of these parts.
  • the tie rods are arranged so that they are arranged in the direction of the force acting perpendicular to the contact / separation surface of the container parts force component of the overpressure. In this way, the tie rods are then expanded in overpressure into a direction parallel to the force causing separation of the parts of the container.
  • the tie rods are arranged between the normal to the contact surface of the container parts spaced ends of the container, since this arrangement allows the greatest possible length of the tie rods. This leaves a maximum possible change in length of the tie rods and thus a maximum gap width between the parts of the container at an overpressure load without the yield strength of the tie rods is exceeded.
  • the arranged between the container parts sealant which are preferably equipped as soft iron rings, ensure that the container under normal operating conditions, that is below a critical pressure, is pressure-tight, so that the contents of the pressure vessel can not escape undesirable from the container.

  • traction means preferably in the form of tie rods, which are braced between the covers.
  • a plurality of traction means is preferably arranged so that they extend outside the container parallel to the longitudinal extent of the tubular part of the container.

In this way, the traction means over the entire circumference of the contact surfaces between the lid and the tubular part can be clamped uniformly. Furthermore, the traction means are evenly loaded by an overpressure in the container. Due to the large number of possible in this arrangement tie rods very high tensile forces can be applied.

So that during the opening and emptying of the pressure vessel no ingredient of the pressure vessel can escape from the container, the opening is pressure-tight lockable.
  • the opening is formed by a recess in the lid, which can be closed pressure-tight by means of a lockable insert.
  • the locking of the insert in the recess is designed so that it closes the container pressure-tight both under normal operating conditions as occurring under the effect of a short-term inside the container pressure, that is, the lock opposes the pressure to resist, at least greater as the one to overcome to trigger the overpressure protection.

  • the insert has an opening through which a tool carrier can be pressure-tight.
  • at least one sealing element is arranged between the tool carrier and the insert, which on the one hand prevents escape of the gas present in the container after the pressure vessel has been opened, but at the same time allows axial and / or rotational movements of the tool carrier in the opening.
