Definitions

  • the invention relates to a sterilization system, more particularly to a system for treating, sterilizing and burning a wide variety of toxic and infectious wastes within a completely closed system.
  • the sterilization means may comprise an in-line electromagnetic wave applicator such as a microwave energy unit.
  • Figure 11 illustrates a variable pitch helical conveyor.
  • the helical conveyor 839 has a full pitch section 847, a 3/4 pitch section 849 and a 1/2 pitch section 851. These sections or segments in the pitch of the conveyor allow for variations in the product flow through the outer chamber.
  • the half pitch section 851 the number of turns is twice that of the full pitch section 847.
  • material moves from the half pitch segment toward the full pitch segment of the helical conveyor coil it slows down and the holding time in the second chamber during which the product is irradiated with electromagnetic energy waves is increased.
  • the heating and sterilization efficiency of the material is improved. In some cases, this may also allow for operating the system at lower power levels.
  • a sloped portion 938 of the refractory liner 904 defines a portion of the floor of the primary combustion chamber 910.
  • the angle of the slope is set to increase the air turbulence adjacent the slope and to maximize the retention time of the product within the combustion chamber in contact with the combustion air.
  • the angle of this slope is dictated by the density and particle size of the material being incinerated and the ash content of the material. The slope can be increased or decreased in dependence on the density and percentage of ash, with denser ashes having a greater tendency to accumulate, thereby requiring a greater slope.

Abstract

La présente invention se rapporte à un système de stérilisation fermé comprenant un dispositif d'alimentation (100) recevant un produit toxique, un premier dispositif de préparation (300) servant à préparer le produit toxique ou infectieux pour la stérilisation, un dispositif de stérilisation (800) servant à stériliser le produit, un dispositif de combustion (900) servant à incinérer le produit stérilisé provenant du dispositif de stérilisation (800) et un dispositif de transport (18) servant à transporter le produit stérilisé du dispositif de stérilisation (800) vers le dispositif de combustion (900). Le système comprend en outre un premier élément de séparation (700) placé entre le premier dispositif de préparation (300) et l'entrée du dispositif de stérilisation (800) afin d'isoler le produit se trouvant dans celui-ci par rapport au produit se trouvant dans le premier dispositif de préparation (300). De seconds éléments de séparation (710) sont aussi disposés entre la sortie du dispositif de stérilisation (800) et le dispositif de transport (18) afin d'isoler le produit stérilisé par rapport au produit se trouvant dans le dispositif de stérilisation (800). Les premier et second éléments de séparation (700, 710) comprennent un corps (701) pourvu d'orifices d'entrée (50) et de sortie (60), un dispositif de transport (702, 703) placé dans le corps (701) afin de transporter le produit de l'orifice d'entrée (50) à l'orifice de sortie (60) et afin d'isoler le produit qui est en train d'être déchargé à travers l'orifice de sortie (60) du produit qui entre par l'orifice d'entrée (50).
