Description

Packaging for flammable bulk goods
DESCRIPTION:
Technical field of the invention
The invention relates to a package for bulk goods comprising: a container designed to hold bulk goods, and a closed bag of airtight material and provided with an oxygen barrier, which bag forms a liner in the container, wherein the bag has a reduced oxygen content and an increased nitrogen content relative to the environment.
Background of the invention
Such a package is known from WO 2014/038931 A. This known package is a package for tobacco that is relatively light and does not ignite quickly. Autoignition will only take place at high temperatures, which do not generally occur during storage and transport.
Transporting bulk goods that ignite relatively quickly, of which the risk of spontaneous combustion is relatively high, by ship, train or truck is expensive because high demands are made on fire safety. In addition, the bulk goods often have to be stored for at least 28 days to reduce the fire risk and must be certified.
In particular, transporting large quantities of charcoal or activated carbon by ship is expensive due to the risk of spontaneous combustion in a warm environment, such as during storage and transport in areas with a warm (subtropical/tropical) climate. That is why very few shipping companies want to transport charcoal or activated carbon and only at high rates.
Charcoal is a lightweight, black residue, consisting of carbon and any residual ash, obtained by removing water and other volatile components from animal and vegetative substances. Charcoal is usually produced by slow pyrolysis, that is, heating wood or other organic substances in the absence of oxygen. Charcoal / Carbon is a product prone to spontaneous combustion and is classified as 4.2 (substances for spontaneous combustion) in the IMDG code and other modal regulations for dangerous goods. The spontaneous combustion of charcoal can cause a fire in a container. Charcoal / Carbon is considered a self-heating substance, which is a substance, unlike pyrophoric substances, which, in contact with air without energy supply, is prone to self-heating. A self-heating reaction can lead to extensive heat generation and fire.
The most combustible substance in the charcoal is carbon, which, when stored in an environment containing oxygen, slowly oxidizes to form carbon dioxide and carbon monoxide. This reaction produces heat, and since charcoal is a relatively good thermal insulator, it retains heat, increasing both the temperature and the rate of oxidation, giving rise to spontaneous combustion.
Such a process is further accelerated by humidification, which is an exothermic process in which heat is released.
Although the disadvantages of charcoal / carbon in storage and transport are known, there is no known solution that can reduce the costs of storage and transport of charcoal / carbon.
Summary of the invention
An object of the invention is to provide a package with which charcoal or activated carbon can be transported in a safe and cheap manner. To this end, the packaging according to the invention is characterized in that: the bag is filled with charcoal or activated carbon, and the container is configured to hold charcoal or activated carbon.
By a container configured to receive charcoal or activated carbon, is meant a container that is sufficiently strong to hold a relatively large amount of charcoal or activated carbon. This may include a so-called big bag (strong large bag with lifting loops), box, crate, the loading space of a truck or a number of smaller bags present on a pallet.
Due to the reduced oxygen content in the bag, spontaneous combustion of the charcoal or activated carbon is virtually impossible. The packaging according to the present invention is therefore extremely suitable and advantageous for packaging charcoal or activated carbon. Although packaging with a reduced oxygen content is known, it has never been thought of investigating whether this is useful in packaging and transporting charcoal / carbon, despite the high costs associated with the latter.
The bulk goods can be placed loosely in the container or packed in small packages (bags of, for example, a few kilograms) in the container or put on a pallet. In the latter case, the bag will be arranged around the relatively small bags. The oxygen barrier may be achieved by using a laminated film for the bag wherein one of the film layers is oxygen impermeable. Oxygen-impermeable materials for films are well known in the packaging industry.
In the case where the bag is fitted as a liner in a container, the container should have a smaller volume than that of the bag and the bag should be shaped such that it will be in contact with the entire or substantially the entire interior surface of the container to ensure that the container absorbs all forces exerted on the bag by the bulk goods, so that the airtight bag is not or hardly loaded and therefore does not have to be of strong design.
An embodiment of the packaging is characterized in that the oxygen content of the gas present in the bag is between 1 and 16%, preferably between 1.5 and 5% and even more preferably about 2%. At a percentage lower than 2%, higher requirements would have to be imposed on the packaging device, which would lead to a sharp increase in investments and costs.
A further embodiment of the package is characterized in that the container is configured to receive charcoal or activated carbon weighing at least 500 kg.
Yet another embodiment of the packaging is characterized in that the bag is provided with an airtight closable connecting nipple to which a vacuum pump can be connected.
The container is preferably a big bag or a cardboard box or wooden box.

Detailed description of the drawings
Figures 1-5 show different steps during the execution of a first embodiment of the method according to the invention. In this method, an airtight bag 1 open at the top (see figure 2) is arranged as a liner in a container suitable for receiving charcoal (ie sufficiently strong), which container is designed as a cardboard box 5 with flaps 7 (see figure 1). Subsequently, the bag 1 is filled with a bulk material 9 (see figure 3).
Subsequently, the box 5 containing the bag 1 filled with the bulk material 9 is placed in a vacuum chamber 11 and subsequently an underpressure is applied in the chamber (see figure 4). After the air pressure in the chamber has been greatly reduced, nitrogen is introduced into the chamber until the underpressure is lifted and the ambient pressure of approximately 1 bar prevails in the chamber. Thereafter, the open top of the bag 1 is sealed airtight with a heated beam 13 (see figure 4). Finally, the vacuum chamber 11 is opened, after which the flaps 7 are folded inwards, thereby closing the box 5 and allowing it to be removed from the chamber (see figure 5). The underpressure is such that the ultimate oxygen content of the gas present in the gas-tight bag is approximately 2%. At an even lower percentage, higher demands would have to be made on the vacuum chamber used, which would greatly increase investments and costs.
Figures 6-9 show different steps during the execution of a second embodiment of the method according to the invention. In this method, an airtight bag 21 open at the top is again arranged as liner in a container suitable for receiving charcoal or activated carbon. The container, in this embodiment, is designed as a big bag 25 provided with loops 7 for picking up. The bag 21 is filled with a bulk material, in this embodiment in the form of charcoal or activated carbon 29 (see figure 6).
Subsequently, the open top of the bag 21 is closed gas-tight and a connecting nipple 31 is fitted in the bag 21 (see figure 7). Thereafter, a vacuum pump 33 is connected to the connecting nipple 31 and air is sucked out of the bag 21 (see figure 8). Nitrogen is then blown into the bag via the connecting nipple 31 until the ambient pressure of approximately 1 bar is again in the bag (slight underpressure over overpressure is also possible). One possibility for introducing the nitrogen is to connect a high-pressure gas bottle filled with nitrogen to the connecting nipple 31 (not shown in the drawings). Finally, the connection nipple 31 is closed airtight (see figure 9). In this way, charcoal or activated carbon packed with reduced oxygen content and thus fireproof is obtained, which is suitable for transport without special measures having to be taken for fire safety.
Figure 10 shows a further embodiment of the packaging according to the invention. A large airtight bag 41 is provided with a connecting nipple 43 around a stack of smaller bags 45 filled with charcoal, the whole being present on a pallet 47 for transport.
Figure 11 shows a further embodiment of the packaging according to the invention. An airtight bag 51 is present as a liner in the cargo hold 53 of a truck 55 and the bag 51 is filled with charcoal 57. A spout of the bag protrudes from a filling opening of the cargo hold and is provided with a connecting nipple 59.
Although the present invention is elucidated above on the basis of the given drawings, it should be noted that this invention is not limited whatsoever to the embodiments shown in the drawings. The invention also extends to all embodiments deviating from the embodiments shown in the drawings within the scope of the invention defined by the appended claims.
