Description
Technical field
The utility model is related to storage tank field more particularly to a kind of double-layer vacuum insulated storage tanks peculiar to vessel with air chamber structure.
Background technology
Current LNG storage tank has following two principal modes：One kind is double-layer vacuum insulated storage tank；Interior outer tank uses metal
Material, and the Sandwich filling thermal insulation material between interior outer tank and vacuumize process；The storage tank of the type has preferable heat preservation
Performance, the storage tank pressure accumulation time is long, has a wide range of applications in LNG tank cars and land LNG gas stations etc., due to such
Land LNG storage tank belongs to static installation mostly, so without considering that the influences such as complicated dynamic loading, inner canister use low temperature resistant material
Material, outer tank generally use carbon steel material is to save the construction cost of entire storage tank；But since the storage tank of the type uses double wall
Structure, tank volume is bigger, and weight is also heavier, cost also higher, is usually chiefly used in volume and is less than 500 cubes of LNG below
Storage tank；As LNG in recent years as the application of marine fuel and is widelyd popularize, double-layer vacuum insulated storage tank is dynamic as LNG fuel
The fuel tank of power ship is widely applied, and the LNG storage tank peculiar to vessel of the type is led to because of its special structure and manufacturing processing technic
The equipment such as the valve, instrument and meter and LNG pump that are connected with storage tank are often arranged in storage tank end, due to the inner canister of LNG storage tank
Bottom is equipped with opening and takes over, once bottom conduit leaks, liquid can leak to storage tank interlayer space, as LNG peculiar to vessel
Fuel reservoir, bottom is equipped with opening or that takes over should be equipped with time screening arrangement, therefore ship specification requires storage tank outer tank palpus
Using low temperature resistant material, the low temperature for causing outer tank to generate after the leakage of inner canister LNG liquid can be born；Due to the cost of low temperature steel
It is 4~5 times of common iron, so tank volume is bigger, outer tank is also higher using the cost that low temperature steel generate, and holds compared to same
Long-pending single layer insulated storage tank does not have price competitiveness, while storage tank overall weight is heavier, and personnel also cannot be introduced into inside
It is overhauled.
Another is the low-temperature storage tank of single wall outsourcing insulation, also referred to as single layer insulated storage tank；Storage tank is using low temperature resistant
Insulating layer is installed in material manufacture, storage tank outer surface using integral spray or split blade type；But storage tank expands with heat and contract with cold and can cause to protect
Warm layer cracks, and influences heat insulation effect, additionally due to vapor enters, also results in heat-insulating property decline；This type is stored up
All openings of tank are all disposed within storage tank top, so not will produce uncontrollable disclosure risk, tank top is equipped with gas in addition
Room, the valve being connected with storage tank, instrument and meter and other equipment etc. being connected with storage tank are directly arranged on storage tank gas chamber, just
In the repair and replacement of equipment；Its shortcoming is that this kind of new LNG storage tank heat insulation effect is poor compared to double-layer vacuum insulated storage tank,
And mounting process is relative complex, needing to install adiabatic cushion block between storage tank and hull, to carry out low temperature heat-insulated.
Utility model content
Construction cost height and not easy to overhaul is led to using double-layer vacuum insulated storage tank to solve existing LNG storage tank peculiar to vessel
Drawback, and use single layer insulated storage tank heat insulation effect is poor, insulating layer is easily destroyed, the problem of mounting process complexity, this practicality
It is novel to provide a kind of double-layer vacuum insulated storage tank peculiar to vessel with air chamber structure.
To achieve the above object, the technical solution adopted in the utility model is：It is a kind of peculiar to vessel double-deck true with air chamber structure
Empty insulated storage tank, including gas chamber, insulating layer, inner canister, outer tank, fixed supporting member and sliding support component, outside the inner canister
Insulating layer is set, and gas chamber is installed on top；Outer tank is set outside the insulating layer；The fixed supporting member is mounted on gas
Room, apart from close side, is placed between inner canister and outer tank with inner canister end socket, and fixed supporting member side is fixedly connected with outer tank,
The other side is fixedly connected with inner canister；The sliding support component is mounted on gas chamber with inner canister end socket apart from remote side, is placed in
Between inner canister and outer tank, sliding support component side is fixedly connected with inner canister, the other side and outer top tank structure sliding contact.
Further, the fixed supporting member includes baffle A, baffle B and supporting member；Outside the supporting member side wall
Portion is provided with baffle A and baffle B；The baffle A is fixed on outer top tank structure；The baffle B is fixed on interior tank wall；The support
Fiberglass or cross-over block can be selected in component.
Further, the sliding support component includes baffle B and supporting member；Setting outside the supporting member side wall
There is baffle B；The baffle B is fixed on interior tank wall；The supporting member and outer top tank structure sliding contact；The supporting member can
Select fiberglass or cross-over block.
Further, it is provided between the inner canister and outer tank and only rolls device；The only rolling device is divided into left and right two parts,
The setting of right part one end is fluted, and the other end is fixedly connected at outer tank end socket, and left part one end, which is provided with, to be connect with upper grooves
Protrusion, the other end are fixedly connected at inner canister end socket.
Further, it is provided with cross-over block between the groove and protrusion of the only rolling device.
Further, the gas chamber is connect with outer tank by expansion pipe.
Further, the gas chamber connection goods pumps, and the valve being connected with inner canister and storage tank measuring instrument are equipped on gas chamber.
Further, it is provided with chamber cover outside the gas chamber；The chamber cover is welded in outer tank.
Further, the interior pot bottom is provided with pump sump in goods pump corresponding position.
Further, the outer tank bottom outer wall connects storage tank saddle.
The utility model has the beneficial effects that：Opening is located at top by storage tank by the way that gas chamber is arranged, and tank bottom is avoided to open
Uncontrollable disclosure risk occurs for mouth；Normal temperature metal material can be used in storage tank outer wall materials, saves the construction of low-temperature storage tank for ship
Cost；Storage tank uses double-wall structure, Sandwich filling thermal insulation material, and is connected using expansion pipe between gas chamber and outer tank
It connects, avoids the low temperature stress generated by thermal boundary shrinkage between interior outer tank, solved while ensureing that storage tank has good thermal insulation property
It expands with heat and contract with cold and leads to the problem of between interior outer tank of having determined；Be arranged between interior outer tank fixed supporting member, sliding support component and
Device is only rolled, fixed supporting member and sliding support component ensure that inner canister varies with temperature free shrink in the axial direction, make
Overall structure of the inner canister because not influencing storage tank when temperature change is deformed, the only rolling device at the end socket of storage tank both ends can effectively be prevented
Only inner canister inner canister rolls, to ensure the service life of storage tank.
