Detailed description of the invention
Hereinafter, in more detail the preferred embodiment of the present invention is described with reference to accompanying drawing.
As shown in Figure 1, the equipment for reducing volatile organic compound discharge according to the present invention is connected to fuel tank 100.
Fuel tank 100 is the petrol storage tanks in boats and ships, and this petrol storage tank receives oil and the fuel that will supply needed for manoeuvre of ship from ground oil chamber (not shown) or other equipment.
In fuel tank 100, drippage pipe 110 is arranged vertically, and room 120 is connected to the upper end of drippage pipe 110.
Room 120 is a kind of containers with pooling feature, and is configured to prevent from forming vacuum when fuel feeding.This room will be described later in detail.
Room 120 is connected to carries oil pipe, and within this year, oil pipe is connected to ground oil chamber or other oil servicing facititiess.
In the upside of fuel tank 100, be usually provided with safety valve 140.
When oil is fed in fuel tank, when the internal pressure of fuel tank raises, safety valve 140 is automatically opened, to be discharged to air from fuel tank by VOC.
In this article, the rising of the internal pressure caused by the supply of oil can not be prevented, because this is natural phenomenon.But, can be prevented by room 120 by the rising introducing the internal pressure that VOC causes, and therefore may reduce the number of operations of safety valve 140, and the possibility being discharged into the environmental pollution caused in air by VOC can be reduced significantly.
Meanwhile, room 120 can have structure as shown in Figure 2.
As shown in Figure 2, room 120 according to the present invention comprises: outer tube 121, and described outer tube is cylindrical shape and forms the main body of this room; Interior pipe 122, described interior pipe is arranged on the center of inside of outer tube to form double pipe structure; Distribute guiding piece 123, described distribution guiding piece is formed in the internal upper part of outer tube 121; Connectivity port 124, described connectivity port is arranged on the upside place of outer tube 121 and is connected to a year oil pipe 130; And a pair first drippage guiding pieces 125 and the second drippage guiding piece 126, they are formed at and extend to bottom between outer tube 121 and interior pipe 122, from the top spirality of room 120 and have phase difference to each other.
The lower end of outer tube 121 is connected to the upper end of drippage pipe 110, and the phase difference between the first drippage guiding piece 125 and the second drippage guiding piece 126 is preferably 180 °.
In this article, there is same shape and described by the term " phase difference " for describing the ripple in physics with the spaced first drippage guiding piece 125 of 180 ° and the second drippage guiding piece 126.But this term is presented for convenience of explanation and strictly means, two structures with same shape and size are arranged along the radial direction of outer tube 121 with the interval of 180 °.
In addition, connectivity port 124 is formed in the upper end of outer tube 121, and distribute guiding piece 123 to be configured to make it distribute towards the first drippage guiding piece 125 and the second drippage guiding piece 126 oil dripped from connectivity port 124 equably, the described oil droplet when oil moves radially along the first drippage guiding piece 125 and the second drippage guiding piece 126 is fallen in drippage pipe 110.
Particularly, the outer tube 121 of room 120 with carry oil pipe 130 and drip pipe 110 and compare there is significantly large diameter, and therefore perform a kind of pooling feature.When dripping the drippage pipe 110 by having same diameter as in the state of the art vertically from the oil carrying oil pipe 130 supply, the dropleting speed caused by gravity becomes and is greater than feed speed, thus forms vacuum, and therefore VOC discharge increases fast.For this reason, room 120 is formed to have than year oil pipe and the diameter dripping Guan Geng great to prevent from forming vacuum.
Particularly, when from carry oil that oil pipe 130 supplies be fed in drippage pipe 110 along the first drippage guiding piece 125 and the second drippage guiding piece 126 with the flow rate reduced (length of the halt owing to increasing) time, described oil is cushioned by room 120 of the present invention.In addition, the air had in relatively large diameter room 120 prevents the difference of the flow rate owing to being caused by gravity and forms vacuum.
Therefore, room prevents the generation of VOC.
In addition, interior pipe 122 is formed by linear tube, and a small amount of oil be therefore fed in interior pipe 122 drips vertically.The oil be supplied to along the first drippage guiding piece 125 and the second drippage guiding piece 126 mixes with the oil dripped vertically through interior pipe 122, and to form bubble (comprising VOC), described bubble rises to the top of room 120.Therefore, VOC can not flow in fuel tank 100, thus reduces the number of operations of safety valve 140, and reduces the discharge of VOC.
In other words, the VOC be collected in the top of room 120 is isolated by the oil be filled in bottom, and when the oil level in fuel tank 100 raises, this room is pressurized, and the VOC therefore with low saturated vapour pressure experiences phase transformation to become liquid oil phase in the top of room 120.As a result, few or VOC free enters in fuel tank 100.
As mentioned above, in the present invention, in the fuel tank 100 oil being loaded into boats and ships, period prevents from forming vacuum, makes the VOC produced by vacuum not enter fuel tank 100.In addition, due to the architectural feature of room 120, the bubble comprising VOC to be formed in room 120 and to be collected in the top of room 120.Therefore, only liquid phase oil is transported in fuel tank 100, makes the amount of the VOC of the oil that can minimize in fuel tank.
In alternative embodiment, as shown in Figure 3, connectivity port also can be formed in the cross side place of outer tube 121.
Embodiment as shown in Figure 3 has identical structure with the embodiment of Fig. 2 except the cross side place that connectivity port is formed at outer tube 121.In addition, should be understood that, embodiment as shown in Figure 3 can illustrate the operation identical with the embodiment of Fig. 2 and effect.
In the embodiment of fig. 3, distribution guiding piece can be omitted.This is because naturally distribution effects can be provided by the pressure of the oil laterally supplied, and distribution guiding piece 123 need not be used.
Certainly, distribution guiding piece 123 is used to make it possible to more effective process.
