Definitions

  • Safety container arrangement for holding dangerous liquids, in particular an organic peroxide
  • the invention relates to acampbeh lteran Extract for receiving dangerous liquids, in particular an organic peroxide.
  • Organic peroxides are relatively unstable compounds. Their use as indicators in the polymerization of monomers and in the crosslinking of polymers is based on their reactivity, ie on their decomposition into free radicals. In their pure form, many organic peroxides are sensitive to impact or even explosive and are considered "dangerous goods", ie they may only be transported, stored and handled under certain conditions. The dangers emanating from you should be controlled by practicing certain regulations and practically eliminated. These provisions concern, among other things, the type of packaging, the limitation of the amount of peroxide in the packaging and safety advice for transport, storage and handling. The transport regulations allow different types of packaging, which depend on the danger or the thermal stability of the products in question.
  • the transport regulations also determine the maximum permissible quantity per shipping container for each product.
  • the containers may contain 25 to 50 kg of peroxide in the delivery form.
  • the permissible amount is drastically reduced e.g. on 5 kg peroxide in delivery form per container.
  • the subdivision into smaller packaging units means that local peroxide decomposition does not immediately affect the entire load but can only spread from one container to another with a considerable delay.
  • a safety container arrangement for holding dangerous liquids, in particular an organic peroxide with separate holding spaces, of which at least one first holding space for holding the dangerous liquid and at least one second holding space for holding another one containing the dangerous liquid Mitigation of the risk potential of miscible liquid, in particular a liquid for diluting and / or neutralizing the dangerous liquid, wherein at least one connection is provided between the receiving spaces, which is closed by at least one security mechanism that releases the at least one connection in the event of danger and a mixing of the Liquids allowed.
  • thermolabile substance such as an organic peroxide
  • a concentration which precludes spontaneous combustion or deflagration under the given conditions are suitable for desensitization, i.e. to reduce the danger, liquid inert substances such as Water and certain organic plasticizers and solvents. If, in the event of danger, the organic peroxide reaches a critical temperature above which there is a risk of self-ignition or explosion of the organic peroxide due to a failure of a cooling device at elevated outside temperatures, the safety mechanism releases the connection between the receiving spaces and thus enables the liquids to mix.
  • the allocation of the recording rooms can be provided, for example, that several smaller recording rooms for receiving the dangerous liquid are provided, which are connected to a single large receiving space for receiving the dilution and / or neutralization liquid via a corresponding number of security mechanisms. If, in the case of a plurality of receiving spaces arranged, for example, on a tanker truck, only a single receiving space reaches a dangerous temperature level due to insufficient cooling, it is only necessary to dilute the dangerous liquid contained in the individual critical receiving space, whereas in the others No mixing takes place in the recording rooms.
  • the receiving spaces which are separate from one another are assigned to one another in pairs, the receiving volume of the further container being dimensioned such that a harmless peroxide concentration which can be handled in conventional containers is established in the two interconnected containers after dilution. If the organic peroxide and the further liquid for dilution or / and neutralization have different densities, it can be provided that the receiving space for receiving the liquid with the higher density is arranged higher than the other receiving space. This arrangement allows the two liquids to mix independently as a result of the upward and downward movements of the two liquids induced by the difference in density.
  • an overpressure relief tion device in particular in the form of a rupture disc.
  • a rupture disc can be provided, for example, in a cover closing a manhole opening.
  • the two receiving spaces be arranged one above the other in a container and separated from one another by an intermediate wall. It is thus also possible to ensure a more uniform temperature distribution over both receiving spaces and also to enable the other receiving space to be cooled when only one receiving space is cooled.
  • the first receiving space comprises an upper floor which is convexly curved at least in the peripheral area, an underbody which is convexly curved at least in the peripheral area and a peripheral wall connecting the upper floor and the underbody, and that the second receiving room of a bowl-shaped container part is formed, which is attached in the convexly curved region of the underfloor of the first receiving space.
  • This structure ensures that the receiving space for receiving the dangerous liquid has a pressure-stable structure, whereas the second receiving space for receiving the dilution and / or neutralizing liquid has a simpler and therefore less expensive structure, and the second receiving space is preferably in a seamless area of the "Pressure vessel" is attached.
  • the pressure capacity of the first receiving space can ensure that when the pressure in the first receiving space increases rapidly, the triggering of the Safety mechanism and the associated decrease in pressure in the first receiving space can not damage the same.
  • the receiving spaces and used fittings be made of stainless steel or pure Aluminum.
  • glass, porcelain or suitable plastics such as polyethylene would also be conceivable.
  • the safety mechanism can comprise a valve mechanism. Electrically, hydraulically or pneumatically operated valve mechanisms of any type are conceivable
  • valve mechanism be replaced by a
  • Glass barrels or glass bulbs for example, can be used as such fuses, which are available for any temperature and the contents of which cannot trigger a reaction with the dangerous liquid.
  • the glass barrels or glass flasks contain inhibitors which lead to an interruption of the reaction when released.
  • Valve seat widens outwards in the opening direction and the Valve plate has a cutting edge on its outside. This arrangement ensures that an inclined position of the valve plate cannot occur during an opening movement and that even if the valve plate is inclined, jamming of the valve plate is excluded and its friction is reduced.
  • valve mechanism is arranged in an inclined region of the intermediate wall such that the pressure spring side of the valve mechanism faces away from the dangerous liquid.
  • the second receiving space has an overflow which extends from the underside of the receiving space to close to the upper end of the receiving space.
  • This arrangement ensures that the receiving space can be filled to a predetermined level without increasing its internal pressure, the fitting provided on the underside of the container being protected from damage at the same time.
  • the safety mechanism comprises a device which causes the liquid to be forced to circulate through the two receiving spaces.
  • a device for example, a membrane or piston arrangement would be conceivable, with which, for example, a liquid displacement could be brought about as a result of a volume reduction in the second receiving space.
  • a pump arrangement can be provided which effects the forced circulation of the two liquids.
  • the invention also relates to the use of a safety container arrangement for transporting and / or storing organic peroxides.
  • a safety container arrangement for transporting and / or storing organic peroxides.
  • the transport and / or storage of the organic peroxide at room temperature or a slightly elevated temperature in the range from 20 ° C. to 50 ° C., preferably in the range from 20 ° C. to 30 ° C, or at temperatures below room temperature in the range from -40 ° C to 20 ° C, preferably in the range from -25 ° C to 20 ° C.
