Description

BACKGROUND OF THE INVENTION The invention relates to an arrangement for the transport and storage of liquid fuels.

Liquid fuels are typically transported in purpose-built tankers with a transport capacity of typically 10,000 liters to 35,000 liters. The driving of such a vehicle requires an ADR tanker license, which can be used to transport dangerous goods in tanks of more than 3000 liters. However, the use of such tank vehicles and fuel tanks corresponding to their capacity for fuel storage does not make sense in situations where the amount of fuel required at any given time is lower or the need for fuel is temporary.

FI publication 8989 U1, ES publication 2189577 A1, GB publication 2034282 A and CN publications 102161465 A and 106927417 A disclose some solutions for the transport and storage of liquid fuels.

Brief description of the invention The object of the invention is to develop a new type of arrangement for the transport and storage of liquid fuels.

The solution according to the invention is characterized by what is stated in the independent claim.

The arrangement for transporting and storing liquid fuels comprises a container transportable by a vehicle, comprising floor, roof and wall structures to form at least one closable transport and storage space, a container arranged at least one transport and storage space for the transport and storage of diesel fuel in at least one IBC (Intermediate Bulk Container) and for the transport and storage of petrol in at least one IBC (Intermediate Bulk Container) in at least one container and at least one for the distribution of diesel fuel and / or 30 petrol from at least one corresponding tank.

The arrangement according to the invention enables, for example, temporary 3 fuel supply in sites where both diesel and petrol are required. Some embodiments of the invention are set out in the dependent claims.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with preferred embodiments, with reference to the accompanying drawings, in which Figure 1 is a schematic front view of a container according to the invention closed, Figure 2 is a schematic front view, Fig. 1 is a schematic side view and a cross-section of the container, and Fig. 4b is a schematic top view and a cross-section of the container transport and storage space in accordance with the classification requirements in the normal use of the container.

In the figures, some embodiments of the invention are shown simplified for clarity.

Similar parts are denoted by the same reference numerals in the figures.

DETAILED DESCRIPTION OF THE INVENTION Figure 1 is a schematic front oblique view of a closed steel container 1 which can be used in an arrangement according to the solution shown.

The container 1 has a substantially rectangular basic structure and comprises opposite side walls 4, 5 extending in the longitudinal direction of the base structure 2, the roof structure 3, the first side wall 4 and the opposite second side wall 5, and the ends of the container 1 form opposite end walls 6, 7 the front wall 6 of the container 1 and the rear wall 7 of the container 1 opposite it. 2 forms the 8th floor of the transport and storage space.

The front end or front part 8a of the transport and storage space 8 is located next to the front wall 6 and the rear end or rear part 8b of the transport space 30 and storage space 8 is located next to the rear wall 7. Fig. 2 is a schematic view of the container 1 of Fig. 1 seen from above and partially cut away from a portion of the first side wall 4, and Fig. 3 is a schematic view of the container of Fig. 1 taken from the rear and from a portion of the second side wall 5.

The size of the container 1 can be chosen freely, but preferably the container is at least 20 feet in length and meets the size standards of containers used in maritime transport, whereby the container 1 can be easily transported both by sea and by road by suitable means. The upper and lower corners of the container 1 have locking points 9, by means of which the container 1 can be locked to the means carrying the container 1 or to other containers when stacking containers on top of each other. In the base structure 2 of the container 1 according to the figures, the portion located at the side walls 4, 5 has openings 10 for forklift tines, whereby the container 1 can be handled by a loading means provided with forklift tines. Furthermore, the bottom structure 2 of the container 1 according to the figures has longitudinal rails 11 of the container 1, by means of which the container 1 can rest in place and by which the container 1 can also be pulled onto a transport means, such as a truck body or a trailer. The first side wall 4 of the container 1 according to the figures is provided with doors 12 which, in the open position, allow access to the transport and storage space 8 from the side of the container 1. The second side wall 5 of the container 1 is closed but could also be provided with one or more doors. The front wall 6 of the container is closed and a hook gripping element 13 is arranged on the outer surface side in connection with the front wall 6, to which the hook of the hook lift can be attached to pull the container 1 to be supported by the transport means. The rear wall 7 of the container 1 is provided with - doors 14 which, in the open position, allow access to the transport and storage space 8 from the end of the container 1. The transport and storage space 8 can thus be opened and closed via said doors 12, 14. The arrangement for transporting and storing liquid fuels further comprises at least one tank located in the transport and storage space 8, but in the embodiment shown in the figures three IBCs (Intermediate Bulk Container) for the transport and storage of diesel fuel in the container, i.e. the first diesel fuel tank 15a, a second diesel fuel tank 15b and a third diesel fuel tank 15c. The first diesel fuel tank 15a is located in the transport and storage space 8 at its first end 8a immediately adjacent to the front wall 6 and from there towards the center of the transport and storage space 8E. The second diesel fuel tank 15b and the third diesel fuel tank 15c are arranged in the same row as the first diesel fuel tank 15a towards the center of the transport and storage space 8. The diesel fuel tanks 15a, 15b, 15c can be placed in the transport and storage space 8, for example in the openings of the first side wall 4.

N through the doors 12 and are locked in place, at least during transport, by means not shown in the figures for the sake of clarity. The volume of each individual diesel fuel tank 15a, 15b, 15c is typically up to 3000 liters.

The arrangement shown in the figures further comprises at least one, but in the embodiment shown in the figures, two diesel fuel refueling cabinets 16a, 16b comprising at least a pump and a hose for dispensing diesel fuel from the tanks 15a, 15b, 15c. For the sake of clarity, no pipe or hose lines are shown in the figures between the tanks 15a, 15b, 15c and the refueling cabinets 16a, 16b. The refueling cabinets 16a, 16b thus form a possible dispensing device for dispensing diesel fuel from the tanks 15a, 15b, 15c.

The arrangement shown in the figures further comprises at least one IBC (Intermediate Bulk Container) tank 17 located in the transport and storage space 8 for the transport and storage of petrol in the container. The petrol tank 17 is located in the transport and storage space 8 at its other end 8b immediately adjacent to the rear wall 7 and from there towards the middle part of the transport and storage space 8. Any other petrol tanks can be placed in the same row as the petrol tank 17 towards the middle of the transport and storage space 8. The petrol tank 17 can be placed in the transport and storage space 8, for example through the opened doors 14 of the rear wall 7, and locked in place, at least for the time of transport, by means not shown in the figures. The volume of each individual gasoline tank 17 is typically up to 3,000 liters.

The distribution of petrol from the tank 17 can be effected by a hand pump arranged in connection with the tank 17 or it can be arranged by means of its own pump and hose in the refueling cabinets 16a, 16b or it can be provided with its own refueling cabinet separate from the refueling cabinets 16a, 16b. The hand pump or refueling cabinet in question forms a tank 17 for a possible dispenser for dispensing petrol. a The arrangement shown in the figures comprises fuel tanks and for diesel © 30 ettd petrol. The arrangement shown in the figures thus enables, for example, temporary fuel supply in sites where both diesel and petrol are required. 0 Since, for example, in earthmoving sites, agriculture and other similar applications involving machinery, the consumption of diesel is typically clearly higher than the consumption of petrol, one petrol tank is often sufficient to cover the need for a choice of petrol. In the embodiment shown in the figures, the volume of each diesel fuel tank 15a, 15b, 15c may be, for example, 3000 liters and the volume of the petrol tank 17 may be, for example, 1000 liters. Since in the arrangement shown the volume of each individual IBC 15a, 15b, 15c, 17 does not exceed 3000 L, the container shown can still be transported without an ADR tank license when the IBCs 15a, 15b, 15c, 17 are fully refueled.

In the arrangement shown in the figures, the diesel fuel tanks 15a, 15b, 15c are located at the front end 8a of the transport and storage space 8, i.e. at the end of the container 1 from which the container 1 is lifted when the container 1 is pulled into the transport space, for example by a hook lift. In this case, the weight distribution of the container 1 both when loading the container 1 into the transport means and when unloading the container 1 from the transport means is advantageous from the point of view of container management.

In the arrangement shown in the figures, the dimensioning of the container 1 and the dimensioning and placement of the diesel fuel tanks 15a, 15b, 15c and the petrol tanks 17 are further implemented so that there is free space next to the petrol tank 17 and between the petrol tank 17 and the diesel fuel tanks 15a, 15b, 15c. , in which case this free space can be used, for example, for the transport of hand fire extinguishers, lubricants and other various accessories or equipment within the carrying capacity of the container 1.

The arrangement shown in the figures further comprises at least one breather line 18 connected to each tank 15a, 15b, 15c, 16 inside the container transport and storage space to form a breather connection for the fuel tanks. The outlet of the breather line 18 from the container 1 is arranged at the rear end 8b of the transport and storage space 8 in the upper part of the transport and storage space 8 and comprises a bleed line discharge connection 19, such as a discharge pipe 20 located outside the container transport and storage space 8 , 5 meters above container 1. During the transport of the container 1, the unloading connection 19 can be placed in the transport and storage space 8 in order to reduce the overall height of the container 1.

The arrangement shown in the figures further comprises an electrical main switch 22 for controlling the supply of electricity to at least one refueling cabinet 16a, 16b for fuel distribution. In addition, the transport and storage space 8 of the container 1 may have lighting, indicator lights or other objects for which a power supply is required.

E The arrangement shown in the figures further comprises a power unit 23 for generating electricity via the electrical main switch 22 to at least one refueling cabinet 16a, 16b for dispensing fuel O, but also for operating other electrical energy-using devices if necessary. The power unit 23 may be, for example, a generator, an aggregate or some other unit suitable for generating and / or storing electrical energy.

Because gasoline has a relatively low flash point (about -40 ° C), gasoline can form an explosive air mixture even at normal storage temperatures. Although the flash point of diesel fuel is quite high (about 55-60 ° C), it can also form an explosive air mixture at very high local temperatures. Therefore, the selection and placement of the equipment included in the arrangement in the container transport and storage space and in the immediate vicinity of the container is preferably implemented based on the classification requirements for explosive atmospheres. The classification of potentially explosive atmospheres is based on the possibility of an explosive mixture of gas, vapor or mist formed in the space by the intended use of the space. In general, in potentially explosive atmospheres, space class O includes spaces in which an explosive mixture of gas, vapor or mist and air is present continuously, for a long time or repeatedly. Room category 1 includes spaces in which, in normal use, an explosive mixture of gas, vapor or mist and air is likely to be present from time to time. Premises in category 2 are those in which, in normal use, an explosive mixture of gas, vapor or mist and air is unlikely to occur. However, if an explosive atmosphere is formed, its occurrence time is short.

Fig. 4a is a schematic side view and cross-section of the container 1, and Fig. 4b is a schematic top view and cross-section of the container 1 transport and storage space 8 and the outside environment of the container . In the normal use of the container 1, the doors 12 in the side walls 4, 5 of the container 1 are closed, the doors 14 in the rear wall 7 are open, the air connections of the tanks 15a, 15b, 15c, 17 to the breather line 18 are open, the doors of the refueling cabinets 16a, 16b are N open and the power unit 23 is running to generate electrical energy through the electrical head center 22 to at least one refueling cabinet 16a, 16b for fuel distribution but also to other electrical energy consuming devices if necessary. As shown above, the outlet of the breather line 18 of the container 1 from the container O 1 is arranged at the other end 8b of the transport and storage space 8 at the top of the transport and storage space 8 and the discharge end 20 of the bleed line 18 is located in the container transport and storage space 8. outside to a height of at least 1,5 m above container 1. Since diesel and petrol vapors are discharged from the discharge head 20 practically all the time during the use of the container 1, a spherical space with a radius of 1500 mm is formed around the discharge head 20 according to space class 0. When the unloading end 20 of the unloading line 19 of the breather line 18 is located outside the container transport and storage space 8 at a height of at least about 1.5 m above the container 1, the space class O formed around the unloading end 20 of the unloading line 18 is located above the container 1. where no one needs to go under normal use.

According to the space classification requirements, an area according to space class 1 with a radius of 1500 mm to 3000 mm and a space according to space class 2 with a radius of 3000 mm to 4500 mm are formed around the discharge end 20 of the breather line 18.

The interiors of the diesel and petrol tanks 15a, 15b, 15c, 17 are spaces according to space class 0. As the diesel and petrol tanks 15a, 15b, 15c, 17 are connected to the breather line 18 and to the refueling cabinet 16a, 16b or, in the case of the petrol tank 17, to any hand pump, with the exception of closed ones, this space class 0 is limited to diesel and petrol tanks 15a, 15b, 15c, 17 to the internal volume.

The transport and storage space 8 of the container 1, i.e. the interior space of the container 1, forms a space according to space class 1 as a space surrounding the diesel and petrol tanks 15a, 15b, 15c, 17. In order to ventilate the transport and storage space 8, the arrangement shown in the figures further comprises at least one ventilation opening 21 provided in the second side wall 5 of the container 1. The ventilation opening 21 can be arranged in the free space between the petrol tank 17 and the diesel fuel tanks 15a, 15b, 15c. . The ventilation opening 21 is arranged in the container 1 so that its distance from the front wall 6 of the container 1 towards the rear wall of the container is at least about 3 meters. Since the transport and storage space 8 of the container 1 forms a space according to space class 1, a ventilation opening 21 is formed above and above the second side wall 5 of the container, centered at a distance of 1500 mm and having a radius of 1 a space of 1500 mm to 3000 mm at a distance of space class 2.

a When the doors of the refueling cabinets 16a, 16b are open, the refueling cabinets © 30 16a, 16b form a space according to space class 1. In this case, a space with a radius of 1500 mm with a radius of 1500 mm and a space with a radius of O of 1500 mm to 3000 mm with a radius of 2 is formed around the refueling cabinets 16a, E 16b.

Fig. 4b further shows a refueling area 24 in which refueling of gasoline N 35 ninja and diesel fuel is to be performed. The refueling area 24 is located in the longitudinal direction of the container 1 from the imaginary refueling area boundary defined in the middle of the container 1 towards the rear wall 7 of the container 1 and past it as far as the distribution hoses of the refueling cabinets 16a, 16b or the petrol tank 7 are sufficient. The refueling area 24 is a space according to space class 1, where the space extending from the border of the refueling area 25 to the front wall 6 of container 1 forms a space according to space class 1 and the space - the holding in accordance with point 2. As can be seen from Figures 4a and 4b, if two or more states in different state classes intersect, that state is defined as a state of a higher state of explosion sensitivity.

The space classification shown in Figures 4a and 4b is implemented in a 20-foot or approximately 6000 mm long container 1. As can be seen from Figures 4a and 4b, all premises classified as explosive within both container 1 and outside in the vicinity of the area extending from the front wall 6 of the container 1 towards the rear wall 7 and possibly past it. The space in front of the front wall 6 of the container 1 then forms a space which is no longer subject to special space class requirements and the equipment located in this area can be chosen freely without taking into account the requirements for equipment to be placed in potentially explosive atmospheres.

In the arrangement shown in the figures, the main electrical switchboard 22 is located in the closed front wall 6 of the container 1 outside the front wall 6, i.e. the transport and storage space 8. Since the front wall 6 of the container 1 is closed and since the discharge end 20 and the vent 21 of the vent line 19 of the breather line 18 are located far enough from the front wall 6 of the container 1, the outer surface of the container 1 is located in requirements. The outer surface of the front wall 6 of the container 1 thus forms an area in which various instruments and devices can be placed freely. Therefore, the switchboard 22 can be freely selected in terms of its characteristics without special space class requirements for the switchboard 22a. As a result, the cost of the power plant 22 © 30 can be kept low.

E The power unit shown in the figures is a movable power unit 0 23, in which case the power unit 23 is taken out of the transport and storage space 8 of the container 1 and connected to the main electrical station, and the power unit 23 is moved back to the transport and storage space 8 during transport.

OF

In the arrangement shown in the figures, the power unit 23 is placed for use outside the transport storage space 8 of the container 1 in front of the closed front wall 6 of the container 1. Since the front wall 6 of the container 1 is closed and since the discharge end 20 and the ventilation opening 21 of the vent line 19 of the breather line 18 are located far enough from the front wall 6 of the container 1, the environment of the container 1 in front of which is no longer subject to specific space class requirements. The front side of the outer surface of the front wall 6 of the container 1 thus also forms an area in which various devices and devices can be freely placed. Therefore, the power unit 23 can also be freely selected for its characteristics without any special space class requirements. As a result, the cost of the power unit 23 can be kept low. In the solution shown, the discharge end 20 of the discharge line 19 of the breather line 18, the diesel fuel tanks 15a, 15b, 15c, the petrol tanks 17, the ventilation opening 21 of the transport and storage space 8 and the border 25 of the refueling area 24 are optimally arranged in the immediate vicinity of the container 1 at least in front of the front wall 6 of the container 1 a space is provided which is not subject to the classification requirements for explosive atmospheres. In even longer containers, this arrangement can also provide spaces on the sides of the container 1 which are not subject to the classification requirements for potentially explosive atmospheres. In this case, equipment that is not subject to the classification requirements for potentially explosive atmospheres can also be included in the arrangement, in which case the cost of such equipment can be minimized.

Thus, the example shown in the figures shows a solution for equipping the container 1 and dividing the transport and storage space 8 of the container 1 and the immediate outside environment of the container 1 into space categories according to the classification requirements for explosive atmospheres, preferably at least a portion of the container 1. and the storage space 8 and / or the immediate external environment of the container 1 comprises an area which is free from the requirements for the classification of explosive atmospheres. Thus, other embodiments according to the claims are also possible. Thus, for example, the location of the discharge end 20 of the breather line 18 and possibly the consequent location of other equipment or means included in the arrangement may differ from that shown in the figures. The unloading end 20 of the container breather line 18 can be placed, for example, in the upper part of the second side wall 5 of the container 1 in the vicinity of the rear wall 35 of the container 1.

According to one embodiment, the arrangement may also comprise at least one IBC (Intermediate Bulk Container) for the transport and storage of an additive for the reduction of nitrogen oxides in the exhaust gases of diesel fuel, typically a solution made of urea and chemically purified water. The volume of each such individual tank is typically up to 3000 liters and can be brought into the transport and storage space 8 of the container 1, for example next to the petrol tank 17. It will be apparent to those skilled in the art that as technology advances, the basic idea of the invention may be practiced in many different ways. The invention and its embodiments - are thus not limited to the examples described above but may vary within the scope of the claims.
