Definitions

  • This invention relates to container decontamination and more particularly a method and apparatus for the thermal decontamination of containers, particularly shipping containers and other enclosed vessels.
  • container is taken to include applications involving enclosed vessels but also can include ducting such as air conditioning ducting for example.
  • the thermal decontamination processes used to-date suffer from a number of drawbacks.
  • plant/vehicles these may need to be moved/transported some distance away from the importing vessel and hence there is always the possibility of pests/insects escaping into the environment prior to the disinfestation procedure being carried out.
  • cost is also a significant issue, not only with plant and vehicles but also other items/imported goods, that may require disinfestation.
  • thermal decontamination apparatus and methods often do not create a sufficiently hostile environment to ensure that. disease pathogens, virus pests/insects etc. are killed off, especially those that might be located in areas which are somewhat inaccessible.
  • the thermal environment used to carry out the disinfestation is maintained for a lengthy period of time. This, however, simply increases the inefficiencies of the known processes and hence the cost.
  • a further problem that can arise as a result of such processes is that of contaminated air exiting to atmosphere whereby disease pathogens, virus, insects and others can be placed into the environment and put bio security at risk.
  • thermal decontamination apparatus and methods for use, in particular with shipping containers or other enclosed vessels including ducting and piping which provides an improved or, at least, an alternative method/means for decontamination and destruction of disease pathogens, virus, insects and others which put bio security at risk and therefore goes some way to addressing at least some of the drawbacks associated with known methods/means.
  • An object of the present invention is to provide such apparatus and method for thermal decontamination.
  • the inventive concept embodied in the present invention is apparatus and method of thermal decontamination which employs forced positive pressure, humid superheated air encapsulated and recycled to form a closed system. This provides an environment to achieve thermal decontamination in a manner which improves efficiency and efficacy as well as preventing contaminated air from exiting to atmosphere.
  • a method of decontaminating a container or closed vessel including the steps of creating a formed positive pressure superheated airflow and directing this into the container/closed vessel and directing an output airflow from the container/closed vessel back into apparatus creating the forced positive pressure superheated airflow.
  • decontamination apparatus including a container or closed vessel; superheated airflow producing apparatus including a flame tube, burner and turbine arranged to create a forced positive pressure superheated airflow; means to direct the input airflow into the container/closed vessel and means to direct a return airflow into the airflow producing apparatus.
  • the thermal decontamination is effected directly within the container or vessel in which items to be decontamination are located. Accordingly, the invention can be used directly with containers used for the importation of items such as vehicles, machinery, foods and organic products. According to a further embodiment, however, the container or vessel to be decontaminated may be placed within another container to allow simultaneous interior and exterior treatment of the container or vessel.
  • Figure 1 is a schematic illustration of apparatus for carrying out the thermal decontamination process in a closed vessel
  • Figure 2 is a somewhat schematic illustration of apparatus according to the present invention employed in a method of carrying out thermal decontamination of a shipping container.
  • a thermal decontamination method whereby air is heated using a diesel or gas fired burner firing into a flame tube. Water or heated water vapour is introduced into the superheated airflow which is moved by a power driven turbine to create high volume forced humid air. This combination of superheated air and water vapour is directed into an enclosed container to thereby carry out thermal killing of disease pathogens, virus, insects, pests and others. The air cycles through the container and is fed (extracted) back into the flame tube/turbine to thereby create a closed system. The flame combustion will heat up the interior/content of the container to effect destruction of the target infestation and will ultimately provides a controllable environment in the container.
  • the method may be carried out without the addition of water vapour if this is necessary to accommodate certain substrates or products within the container.
  • the method can be carried out directly within a shipping container in which the item or items to be decontaminated is/are located.
  • the shipping container could be one which has been imported into the country and for which decontamination of the products within the container is required.
  • the shipping container could be simply a container used .to create a vessel into which product, to be decontaminated, can be . placed.
  • heating apparatus as hereinafter described, can be coupled to a shipping container into which a vehicle can be driven. Once the vehicle has been placed in the container the container can be closed up and the decontamination procedure carried out. In this way a relatively low capital cost decontamination plant for motor vehicles, machinery or other items can be achieved.
  • the apparatus 10 for creating the superheated air/water vapour is connected directly to an enclosed vessel e.g. a conventional shipping container C.
  • the apparatus 10 can be mobile in nature (see Figure 2) by being mounted on a wheeled chassis 12 which can be connected to a towing vehicle 13. In this way the apparatus 10 can be moved about to enable it to be positioned adjacent and connected to a shipping container wherever the shipping container may be located.
  • the shipping container C can have the doors D open and the apparatus 10 abutted against the doors.
  • the apparatus 10 therefore incorporates a sealing arrangement 14 which not only seals against the forward facing edges of the open doors D but also provides a seal across the top and bottom of the doors and up to the end of the container C. In this way a complete seal is formed between the apparatus 10 and the interior of the container C. It will be evident that other arrangements to achieve a substantially sealed connection with the open end of the container C can be employed.
  • the apparatus 10 can be engaged with a fixed wall such as the closed end wall of the container C.
  • a fixed wall such as the closed end wall of the container C.
  • suitable ducting connected between an outlet of the apparatus 10 and a wall of the container C, and between the wall of the container C and an inlet of the apparatus.
  • Such an arrangement is suitable when the container C is to function solely as an enclosed vessel into which say motor vehicles, machinery and the like can be placed through the open doors and decontamination once the doors have been closed to complete the enclosed vessel. This is the type of arrangement as shown in Figure 1 .
  • the apparatus 1 0 includes a powered turbine 1 5, a burner 16 and a water injector 17.
  • Fluid tanks 18 are provided for suppling water to the water injector and supplying fuel to the burner 16 (when the burner is oil/diesel powered) and also the prime mover (engine) of the powered turbine 1 5.
  • the apparatus 10 can, for example, be a suitably adapted BioVapour (trade mark) thermal heating apparatus produced and marketed by Dearcorp Limited.
  • the apparatus 1 0 further includes an outlet duct 1 9 whereby superheated air/water vapour can exit from the apparatus 10. It also includes an inlet duct 20 whereby exiting vapour/superheated air from the container C can be retuned to the flame tube and turbine.
  • the apparatus 10 with the container C forms a closed system. It will be appreciated that in such an arrangement input air is drawn into the burner but will be controlled to be only sufficient to maintain combustion.
  • the apparatus and method is suited for products and surfaces capable of accepting high temperature such as metal, steel, wood and others. Therefore, it is suitable for decontamination of empty sea containers as well as sea containers containing such products capable of accepting high temperatures.
  • the products may, as previously disclosed, already be contained within the sea container or placed therein for the decontamination procedure to be carried out.
  • the heating apparatus 10 can be operated in accordance with the following:-
  • Burner Capacity 50kw to 1 ,000kw Most preferred 250kw to 600kw
  • Air Volume 10,000m 3 /hr to 1 100,000m 3 /hr Most preferred - 20,OOOm 3 /hr to 80,000m 3 /hr
  • Burner Capacity 50kw to 1 ,000kw Most preferred 250kw to 600kw
  • the treatment duration in both applications mentioned above is relative to container size based on approximately 32m 3 and 72m 3 capacity.
  • Apparatus of the type described above used to carry out a thermal decontamination method on an enclosed vessel has been found to be extremely effective yet efficient in operation and with improved efficacy over known thermal decontamination methods.
  • the employment of forced positive pressure, humid superheated air into an enclosed vessel and then recycled in a closed system is the basis of the invention. This forcing of positive pressure superheated air into the container will create a pressure in the container such that venting via a filtered vent 21 may be required in order to control internal pressure within the vessel C.
  • the use of the powered turbine 1 5 gives velocity and volume of air movement.
  • good driving/ penetrating of the air and water vapour into nooks and crannies in the item(s) to be decontaminated is achieved.
  • This forces - heat transfer and the turbulence/ buffeting achieved by the forced positive pressure humid superheated air creates an environment in which the target infestation will be destroyed.
  • With inaccessible areas such as to be typically found in machinery, vehicles and the like, there will be potentially cold areas in which the target infestation may otherwise survive.
  • the forced air flow ensures that such cold areas are minimised and, indeed, the turbulence/buffeting effect of the forced pressurised air flow can achieve the sucking out of target infestation from such areas.
  • the substrates to be treated may be before, during or after heat treatment washed down with a decontamination fluid at a temperature ranging between 2O 0 C to 200 0 C.
  • the system may be operated without the addition of water vapour if necessary to accommodate certain substrates or products.

Abstract

L’invention concerne un appareil et un procédé de décontamination thermique de récipients d’expédition et autres récipients clos. Un appareil (10) ayant un tube à flamme, un brûleur (16) et une turbine (15) est utilisé pour créer un écoulement d’air surchauffé (dans lequel de l’eau peut être introduite par l'intermédiaire d’un injecteur (17)). Cet écoulement d’air est dirigé par le conduit (19) dans le récipient C avant de retourner par l'intermédiaire du conduit (20) dans l’appareil (10) pour former ainsi un système clos. L’air (de préférence humide) surchauffé ayant une pression positive forcée provoque le chauffage de l’intérieur du récipient C (et de son contenu) afin de détruire l’infestation cible. La température de l’air pénétrant dans le récipient peut être comprise entre 750 °C et 5 000 °C avec un volume d’air compris entre 10 000 m3/h et 100 000 m3/h. La durée du traitement peut être comprise entre 1 minute et 48 heures.
