Abstract
The utility model discloses a self-balancing tank ship used for transporting LPG, and relates to the technical field of A-type tanks of LPG ships. A columnar tank is arranged in a hull, wherein the cross section of the columnar tank along the hull is of a diamond shape; a middle longitudinal bulkhead is arranged in the tank in the length direction of the tank from the bottom to the top of the tank and divides the tank into a left cavity and a right cavity; a gas channel which is communicated with the left cavity and the right cavity is formed in the upper portion of the middle longitudinal bulkhead. Because the columnar tank provided with the left cavity and the right cavity is adopted for the self-balancing tank ship, drastic oscillation of the liquid level in the tank due to swing of the hull can be weakened; even if gas expansion happens in one cavity due to oscillation or other factors, balance can still be achieved through the gas channel; furthermore, the self-balancing tank ship can bear liquid pressure from the two sides, and therefore the safety of transportation can be effectively guaranteed. Meanwhile, the tank is divided into the left cavity and the right cavity, which is beneficial to shipment balance and safety of the ship.
Description
Technical field
The utility model belongs to boats and ships production technology, particularly LPG ship A type tank production technical field.
Background technology
Autogas (Liquefied petroleum gas, being called for short LPG) boats and ships are mainly having density, spread of viscosity is large, liquid goods boil-off gas pressure is high, high-solidification point, high volatile volatile, high heat sensitivity, inflammable, poisonous, be corrosive and reactive liquefaction of gases is stored in and in special container, carries out safe and reliable transportation, and can load and unload in liquefaction.Therefore, for transporting the design of these type of boats and ships and the technique of construction is very complicated.
Storage for the LPG boats and ships that transport requires conventionally there are three kinds: full voltage type, design temperature for-10 ℃, operation pressure be 1.76MPa; Half cold/semi-voltage type, design temperature for-50 ℃, operation pressure be 0.4 ~ 1.0MPa; Full-cool, design temperature for-50 ℃, operation pressure be 0.028MPa.
Can meet with various stormy waves owing to transporting at sea, when boats and ships wave because of wave, the autogas loading can vibrate, especially significantly vibration can make autogas generation gas cause cubic expansion and Stability of Ship is had an immense impact on, and this hidden danger is definitely strictly to forbid.
Utility model content
The purpose of this utility model is the canned boats and ships for conveying liquified hydrocarbon gas with self-balancing of a kind of safety misadventure that prevents autogas generation vibration and bring of design.
The utility model comprises hull, in hull, arrange and prolong the cylindricality tank body that hull transversal surface is prismatic, in tank body, along the length direction of described tank body, by bottom to the top of tank body, the central longitudinal bulkhead that tank body is divided into left chamber and right chamber is set, on the top of described central longitudinal bulkhead, the gas passage that is communicated in left chamber and right chamber is set.
Because the utility model adopts the cylindricality tank body with left chamber and right chamber, be conducive to weaken the significantly vibration that liquid level in the tank body bringing occurs to swing because of hull, both just there is the reason because of vibration or other side to cause one of them chamber generation gas expansion, also can reach balance by gas passage, and can bear bilateral fluid pressure, effectively to ensure the safety of transportation.Meanwhile, tank body is separated into shipment balance and the safety that left chamber and right chamber are also beneficial to boats and ships.
In addition, the utility model also arranges in the bottom of described central longitudinal bulkhead the fluid passage that is communicated in left chamber and right chamber.The liquid level that can realize in left and right chamber by fluid passage keeps consistency.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model prolongs in the interior layout of hull 1 the cylindricality tank body 2 that hull transversal surface is prismatic.
In tank body 2, along the length direction of tank body 2, by bottom to the top of tank body 2, arrange tank body 2 is divided into the central longitudinal bulkhead 5 that the rigid material of left chamber 3 and right chamber 4 is made.
Top at central longitudinal bulkhead 5 arranges the gas passage 6 that is communicated in left chamber 3 and right chamber 4.
Bottom at central longitudinal bulkhead 5 arranges the fluid passage 7 that is communicated in left chamber 3 and right chamber 4.
Claims (2)
1. the canned boats and ships for conveying liquified hydrocarbon gas with self-balancing, comprise hull, it is characterized in that arranging and prolonging the cylindricality tank body that hull transversal surface is prismatic in hull, in tank body, along the length direction of described tank body, by bottom to the top of tank body, the central longitudinal bulkhead that tank body is divided into left chamber and right chamber is set, on the top of described central longitudinal bulkhead, the gas passage that is communicated in left chamber and right chamber is set.
2. boats and ships according to claim 1, is characterized in that, in the bottom of described central longitudinal bulkhead, the fluid passage that is communicated in left chamber and right chamber is set.
