Description

Transport-import containers of all kinds, d. H. especially in a lockable Construction, accounting for about 20% with significant gaseous Pollutant concentrations in the interior and thus when committing the Containers burdened by persons in the breath.

Were For the purposes of the invention are primarily piece goods of all kinds, especially those in boxes or sacks packed and thus stackable, but also unpacked, as well packed bulk goods; secondarily unpacked Bulk goods and containers Liquids.

• – zum Schutz vor Schädlingen diesbezüglich bewusst begast wurden,
• – verursacht durch ihren Herstellungsprozess oder ihre Stoffzusammensetzung nachgasen oder
• – vor dem Transport zur Reduzierung von Schimmelbefall speziell behandelt wurden.

These are not only dangerous goods in the true sense, but also to cargo contents of all kinds, ie in particular goods, their packaging or parts thereof, in part

• - were deliberately fumigated for protection against pests in this respect,
• - re-gassing caused by their manufacturing process or their composition of matter or
• - specially treated before transport to reduce mold growth.

These are in nature and form in this regard known pollutants that are either gaseous under the conditions prevailing in the container, or other substances, eg. As liquids that occur temporarily gaseous due to their vapor pressure. Pollutants in this sense are, for example:
Chloropicrin / trichloro-nitro-methane, cis- and trans-1,2-dichlorotethene, dichloromethane, ethylbenzene, carbon disulfide, toluene, trimethylbenzene with all isomers, xylene with all isomers, phosphine, sulfuryldifluoride, benzene, trichlorethylene, 1,2-dichloroethane , 1,3-dichloropropene with isomers, formaldehyde, 1,2-dichloropropane, bromomethane, dibromoethane, and iodomethane.

These Pollutants and their gaseous components (harmful gases) are especially useful for manual unloading, which is often common with imported containers is, opening or walking the container in the air or immediate surroundings, for example in the door area of the container, dangerous for persons or harmful to health. All in this respect coming in contact persons, in particular when working in a container with such noxious gases, should or must be protected. These people must be effectively protected from these noxious gases.

measurements the container air, d. H. the respective pollutant concentrations, give about a possible danger regarding harmful gases in the usual way information.

Around with the contaminated goods originating from the containers where a relevant pollutant concentration was detected, safe to handle, z. B. unloading, storage and placing on the market, It is often necessary to degas these before. Under degassing In particular, it is understood to be sufficient to ventilate the Concentration of noxious gases in the container to one for the Reduce personnel harmless levels.

This is particularly necessary in such a type of loading and / or Discharge, which can be done primarily manually, since not technically possible. This is for example in the case of containers, especially import containers, in which the Goods, such as stacked boxes, not on transport pallets stand, d. H. the goods not with the usual technical unloading aids, such as forklifts or the like., Can be unloaded.

Under Ventilation is understood in the sense of the invention in particular that in a defined space, which towards the environment partially is not closed, there is a pressure difference and / or generated so that there will be a current / circulation is. This causes the gas-air mixtures in this room (container air) and mix air from its surroundings. If, for example, fresh air is introduced into such a room this regularly displaces the space in the room Harmful gas-air mixture, causing a decrease in concentration of the noxious gas in the gas-air mixture in the room leads.

A typical situation with goods from import containers is that the Goods due to the long stay during transport are completely durchgegast. That is, the gaseous pollutants (Noxious gases) are not only found in the unloaded part of the container, but have spread in the goods and / or in their packaging.

in the closed container is regularly no or only a very low flow / circulation (air movement), especially caused by different temperatures and small openings, such as cracks and crevices, can be found. Such Containers are closed, but often not hermetically sealed.

If these goods are unloaded, ie for the first time surrounded by outside air, spontaneous release (outgassing) of pollutants from the goods and / or their packaging occurs in the unloaded part of the container. These gaseous pollutants can thus also enter the respiratory air. Depending on the type and concentration of the outgassing substance, the type and packaging of the goods and the respective local factors (Environmental conditions), the process of outgassing can last a very long, ie up to several days, and a rapid unloading of the container is not possible without the use of protective equipment against these noxious gases, especially during manual unloading.

moreover holds another uncontrolled aftergassing, so another Emission of pollutants after initial ventilation has already taken place, again dangers for the further handling of the goods and / or in their packaging. In these cases, the Goods before further use, d. H. the renewed contact with Persons, for example in the intermediate storage at the wholesaler or the delivery to end customers to be degassed again.

To conditions are to be improved or created, which make it possible for the pollutants to leave the goods and / or their packaging leak and get into the surrounding air. That is, the goods are set up, for example, isolated or fully or partially unpacked, so that the pollutants delivered as large a surface as possible can be. Subsequently, the pollutants transported away from the room with the air flow and, if necessary, treated in the usual way on.

The Goods are considered "adequately ventilated" within the meaning of the invention, if after airing, no danger to persons by emitted gaseous pollutants (noxious gases) more emanating from them. This condition of a "sufficient Ventilation "can be used in normal risk assessments, based on measured data of the respective pollutant concentration, be determined. The goods are in a condition of "sufficient Ventilation "no longer with gaseous pollutants (Harmful gases) contaminates or falls below a defined limit the pollutant concentration, which for example by health authorities or the like can be determined.

• 1. Der importierte Container, welcher die belasteten Waren enthält, wird, beispielsweise von der Zollstelle, zum Lüftungsort (Entgasungsort), welcher oft nicht der Ort des Empfängers der Ware ist, transportiert. Damit ist regelmäßig ein zusätzlicher Transport zum Lüftungsort erforderlich, so dass zusätzliche Kosten für den Transport und die Anmietung des Ortes der Lüftung (Lüftungsort) notwendig sind.
• 2. Die Waren werden am Lüftungsort kontrolliert Entladen (Kontrollmessungen, Arbeitsschutz) und an einem lüftungsfähigen Ort aufgestellt, zumeist in einer Lagerhalle oder ähnlichen Lagerplätzen. Die oft vereinzelt aufgestellten Waren, um ein verbessertes Lüften zu ermöglichen, lüften oft ohne Fremdbelüftung, so dass das Lüften relativ viel Zeit, d. h. ggf. mehrere Tage, beansprucht. Wird ein Nachgasen erwartet, wird vorsorglich die Lüftungsdauer verlängert.
• 3. Nach ausreichender Lüftung werden die Waren umgeladen und verladen und dem Empfänger zugestellt. Das Messen der verbliebenen gasförmigen Schadstoffe bzw. deren Konzentration ist mit relativ großen Unsicherheiten (Messtoleranzen) behaftet, da insbesondere die Messung in großen Räumen, wie Lagerhallen, erfolgt, so dass in üblicher Art und Weise Messtoleranzen zu berücksichtigen sind. Alternativ findet vorsorglich ein längeres Lüften als eigentlich erforderlich statt, so dass ein entsprechender Zeitverlust hingenommen wird. Ein eventuelles Nachgasen kann dabei nur schätzungsweise einbezogen werden. Außerdem müssen die Waren oftmals wieder eng zusammengeschichtet werden, damit sie sicher zum Empfänger transportiert werden können. Die ausreichende Lüftung wird mittels Messung somit vor der Verladung festgestellt (ohne festgelegte Standards).
• 4. Dabei kann durch ein Nachgasen der Waren erneut die Gefahr entstehen, dass bei der Entladung am Empfangsort, d. h. beim Empfänger, hohe Konzentrationen von Schadgasen die Atemluft belasten können. Diesem Effekt kann nur mittels zusätzlicher ausreichender Lüftung, z. B. Entladung mit geöffneten Planen oder zusätzlichem Gebläse bei geschlossenen Fahrzeugen, entgegengewirkt werden.

In practice, the following procedure (state of the art) has prevailed at present and for many years:

• 1. The imported container containing the loaded goods, for example, from the customs office, to the ventilation (degassing), which is often not the place of the recipient of the goods, transported. Thus, an additional transport to the place of ventilation is regularly required, so that additional costs for the transport and rent of the place of ventilation (ventilation) are necessary.
• 2. The goods are inspected at the place of unloading (control measurements, occupational safety) and placed in an airworthy place, usually in a warehouse or similar storage areas. The often isolated items to allow for improved ventilation, ventilate often without forced ventilation, so that the ventilation takes a relatively long time, ie possibly several days. If afterglow is expected, the ventilation time will be extended as a precaution.
• 3. After sufficient ventilation, the goods are transhipped and loaded and delivered to the recipient. The measurement of the remaining gaseous pollutants or their concentration is associated with relatively large uncertainties (measurement tolerances), since in particular the measurement in large spaces, such as warehouses, takes place, so that in the usual way measuring tolerances are taken into account. Alternatively, as a precaution, a longer ventilation than actually required takes place, so that a corresponding loss of time is accepted. A possible aftergassing can only be estimated. In addition, the goods often have to be re-stacked close together so that they can be safely transported to the recipient. Sufficient ventilation is thus determined by measurement before loading (without specified standards).
• 4. In this case, by re-gassing of the goods again the risk arise that during discharge at the receiving location, ie at the receiver, high concentrations of noxious gases can pollute the air. This effect can only by means of additional adequate ventilation, z. As discharge with open tarpaulins or additional blower in closed vehicles, to be counteracted.

task The invention is to a device and a plant ready to provide that overcome the disadvantages of the prior art and in particular controlled ventilation up to one ensure adequate ventilation. These should as technologically simple, safe and effective as possible.

Furthermore to the invention for the specific conditions be suitable for the handling of import containers. Aftergassing goods or the degree of gas afterglow of this product should be reasonable be determined and a safe ventilation even when unloading be guaranteed at the recipient. The security the loading staff against adverse effects by noxious gases, gassing and especially aftergassing goods should also increase.

The The object of the invention is achieved by a ventilation container solved according to the features of claim 1.

It is essential that the ventilation container according to the invention is operable by a method, which contains at least the following steps: introduction of the contaminated product into a closable space via a loading opening and depositing at the storage point, wherein at least the air-gas mixture located in the interior of the room escapes via at least one venting point and the escaping air-gas mixture primarily in a direction away from the loading port in the interior of the room toward the vent point flows; Closing the loading opening of the room; Ventilating the interior of the container, wherein a conveyor moves the air-gas mixture located in the interior of the room and this air-gas mixture is passed through an air outlet system to the outside and air via an air inlet system in the interior of the room; Measuring the re-gassing behavior of the goods as an intermediate step during the step ventilating the interior of the room and / or after the step ventilating the interior of the room; Opening the room and unloading the goods in a condition of adequate ventilation.

Essential is that through the use of the invention Solution in particular prevents harmful gases in the breathing air of persons arrive. This is especially true achieved that during manual contact with the goods such a flow exists that directs any remaining harmful gas away from the person, so that it can not get into the air.

• 1. Kontrollierte Entladung in den otsveränderlichen Lüftungscontainer bei laufender Luftabsaugung entgegen der Zutrittsrichtung des Ladepersonals. Dadurch wird die Schadgaskonzentration bereits während des Umladens reduziert. Der Ort des Umladens kann dabei frei gewählt werden, z. B. bereits auf dem Containerbahnhof vor Zustellung der Ware. Es entfällt die extra Transport/Umfuhr, d. h. der An- und Abtransport, der Waren zum bisher üblichen Lüftungsort. Die Lüftung beginnt bevorzugt sofort mit dem Beladen des Containers.
• 2. Waren lüften im Container unter kontrollierten Bedingungen. Es kann die Luftwechselrate bestimmt und gezielt verändert werden. Es sind genauere Konzentrationsmessungen in der Abluft ermöglicht. Es kann außerdem das Nachgasungsverhalten der Waren bei ausgeschalteter Lüftung und verschlossenen Lüftungsöffnungen, beispielsweise können mehrere Vergleichsmessungen in einer solchen Phase ohne Lüftung im Container erfolgen, bestimmt werden. Damit ist eine sehr genaue Gefährdungsanalyse für die nachfolgenden Behandlungsschritte der Waren, insbesondere bezüglich eines eventuellen Nachgasens, ermöglicht. Ein erneutes Beladen und die damit verbundenen Gefährdungen für die beteiligten Personen, insbesondere das Verladepersonal, sowie die damit verbundenen Kosten entfallen bzw. können auf den tatsächlich notwendigen Aufwand reduziert werden.
• 3. Nach ausreichender Lüftung wird der Container mit der Ware dem Empfänger zugestellt. Durch die geschlossene Bauweise des Containers werden zusätzlich Kosten durch geringere Anforderungen an die Ladungssicherung gespart. Die Waren werden vorzugsweise bei laufender Luftabsaugung entgegen der Zutrittsrichtung entladen. Dadurch ist dabei gewährleistet, dass nachgasende Schadstoffe primär vom Arbeitsplatz weg transportiert werden; eine zusätzliche Maßnahme zur Erhöhung der Sicherheit ist erreicht.

The present invention provides a simplification and acceleration of the method of venting / degassing and provides more safety in the workplace. This is achieved in particular as follows:

• 1. Controlled discharge into the variable ventilation container while the air extraction system is running against the access direction of the loading staff. As a result, the harmful gas concentration is already reduced during the reloading. The place of reloading can be chosen freely, z. B. already on the container station before delivery of the goods. It eliminates the extra transport / transfer, ie the transport to and from the goods to the usual ventilation location. The ventilation preferably starts immediately with the loading of the container.
• 2. Goods air in the container under controlled conditions. The air exchange rate can be determined and specifically changed. It allows more accurate concentration measurements in the exhaust air. It can also be the Nachgasungsverhalten the goods with ventilation switched off and closed vents, for example, several comparative measurements can be made in such a phase without ventilation in the container determined. This is a very accurate risk analysis for the subsequent treatment steps of the goods, in particular with respect to a possible Nachgasens enabled. Reloading and the associated risks for the persons involved, in particular the loading personnel, as well as the associated costs are eliminated or can be reduced to the actual necessary effort.
• 3. After sufficient ventilation, the container with the goods is delivered to the recipient. Due to the closed design of the container, additional costs are saved due to lower load securing requirements. The goods are preferably discharged while the air extraction against the access direction. This ensures that post-gases are primarily transported away from the workplace; An additional measure to increase safety has been achieved.

1 shows a ventilation container according to the invention 1.1 with a loading opening in a sectional view.

The transportable ventilation container 1.1 has a closed design, so that its interior has a closable space 1 forms, which can also be closed airtight. The shape and dimensions of the container preferably correspond to those of a DIN ISO container ( DIN ISO 668 ). This ensures that the ventilation container according to the invention 1.1 Can be easily integrated into the existing international transport system. For closing serves a usual closable loading opening 2 on one of the two ends 1.2 and 1.3 , here the front page 1.2 , the box-shaped ventilation container 1.1 is arranged vertically in the usual manner. The loading opening 2 is shown in the closed state.

At the front 1.2 is at least a closable air intake 3.21 , which can also be hermetically sealed, arranged.

The air intake 3.21 can have a flap, so that in particular there is protection against ingress of splashing water during transport. In addition, the ventilation container 1.1 be closed in order to "sweat" the contents of the container, ie to let aftergases, in order to be able to determine, inter alia, the Schadgas- or -stoffkonzentration the goods.

Are inlet slots in the beads of the doors with raised sheets on the Arranged inside, penetrating rainwater is released when airing and transport prevented.

air outlet 3.11 :

• – zurückgesetzter Rohrstutzen an Außenseite: bei Ausfall des inneren Gebläses kann außen ein Ersatzgebläse angeflanscht werden
• – Verschlussklappe: Schutz vor Regenwasser, eindringenden Spritzwasser während des Transports und Möglichkeit, Container „schwitzen” zu lassen um über Messungen das Ausgasungspotential der Güter ermitteln zu können
• – Ermöglicht eine Filterung und/oder Reinigung des nach außen geleiteten Gas-Luft-Gemisches
• – Ermöglicht eine Einleitung oder Zumischung des zuvor gefilterten Gas-Luft-Gemisches in den Lufteinlass.

Air outlet in the front area (wide or front side)

• - Recessed pipe socket on the outside: if the internal fan fails, a replacement fan can be flanged on the outside
• - Closing flap: Protection against rainwater, penetrating splash water during transport and possibility to "sweat" container to be able to determine the outgassing potential of the goods via measurements
• - Allows filtering and / or cleaning of the outwardly directed gas-air mixture
• - Allows an introduction or admixture of the previously filtered gas-air mixture in the air inlet.

Funded by:

• - Sizing of the sucking unit so that even with increasing flow resistance (eg. Paper clogs part of the intake pipe) sufficient air delivery is guaranteed
• - automatic control of the direction of rotation, control possible by operator
• - if required between conveyor and outlet port clamped an air filter by means of hoses

Air manifold 3.12 :

• - perforated (protective grille for Conveyor)
• - to adjust air intake in height, be Parts of the intake manifold covered with wrap-around panels

air guides 7 , on the ceiling:

• - because most goods are not utilize the entire loading height, be on the ceiling side louvers appropriate. These reduce the airflow over the estate and redirect the flow of air back through the property (increases efficiency)
• - The louvers are deflated and will positioned with progressing loading. They will be during the discharge back up "and" do not disturb the further discharge

signaling device 9 /Traffic light:

• - signals receivers, when after the ventilation is switched on the container doors can be opened and the discharge can begin
• - red and green signal light on container door
• - red light signals: safe door opening is not possible
• - green light: safe door opening possible
• - green burns when conveyor runs and at least the entire container air once swapped was (control of speed monitor and timer)
