Definitions

  • the invention relates to a mist pot according to the preamble of claim 1.
  • Such a mist pot has, for example, a volume of the order of 10 liters, it is filled with a pyrotechnic active mass.
  • the pyrotechnic active material usually consists of metal powder, an oxidizing agent and a chemical which develops an acid anhydride when burning the active material.
  • the acid anhydride absorbs the existing ambient humidity, which precipitates as fog, which is impermeable to visible light.
  • the fog thus forms a privacy screen.
  • From the DE 102 26 507 A1 is, for example, a smoke projectile with a pyrotechnic active material for generating an infrared emitting and visually impermeable aerosol known.
  • a composition of the pyrotechnic active material of this known smoke projectile is in the DE 199 14 097 A1 described.
  • a mist throwing body the effective mass of which is formed by a modular structure of a nebulized body, which has two different active bodies, wherein the one active body causes a temporally fast mist structure and the other active body has a long burning time, is from the DE 10 2006 008 309 A1 known.
  • the invention has for its object to provide a mist pot of the type mentioned, which ensures optimal fog generation even at low ambient humidity.
  • the mist pot according to the invention has at least one container filled with water, which is destroyed during the ignition of the active mass.
  • the at least one destructible container is filled with a mixture of water and an antifreeze. This can prevent the water from freezing at correspondingly low temperatures, ie. H. frozen to ice and becomes ineffective for mist production.
  • the at least one container When the mist pot is ignited, the at least one container is destroyed, so that the water stored in the container binds to the acid anhydride and optimum mist generation takes place even at low atmospheric humidity.
  • the figure shows a schematic representation of an embodiment of the mist pot 10 with a bucket-shaped housing 12 for a pyrotechnic active mass 14.
  • the housing 12 is closed by means of a cover 16.
  • the lid 16 is provided with an igniter 18, which is provided for igniting the active mass 14 - after a predetermined delay time.
  • the pyrotechnic active mass 14 consists of metal powder, an oxidizing agent and a chemical which develops an acid anhydride upon combustion of the active mass 14.
  • At least one container 20 which has a filling 22 made of water or preferably a mixture of water and an antifreeze.
  • the at least one container 20 is expediently formed by a plastic bag 24 which is destroyed in the ignition of the active mass 12.
  • the water released from the at least one destroyed container 20 binds to the above-mentioned acid anhydride and forms a strong, ie dense, visually impermeable mist even at a low ambient humidity.
  • the mist pot 10 according to the invention can therefore be used effectively even with a low ambient humidity.
