Abstract
The utility model discloses a prestressed pressure vessel which comprises axial prestressed tendons, circumferential prestressed tendons and prestressed concrete blocks. The prestressed pressure vessel is characterized in that the concrete blocks are fixed into a cylinder through the axial prestressed tendons and the circumferential prestressed tendons, inner walls of the concrete blocks are provided with a heat preserving material layer, inner walls of the heat preserving material layer are provided with a lining, the upper end of the vessel is provided with an end cover, and pipelines extending outside the vessel are arranged in the middle, the upper portion and the bottom portion of the vessel. The prestressed pressure vessel is suitable for large-scale medium and low pressure vessels, particularly, heating vessels in large-scale areas. Anti-pressure ability of the prestressed pressure vessel is improved through stress, applied in advance, opposite to the working pressure of the vessel. The prestressed pressure vessel is formed through splicing of a plurality of detachable concrete blocks so that the defects that an ordinary large-scale pressure vessel is complex in manufacture process, difficult to move, and the like are avoided.

Background technique
The application of pressurized container in production field is very extensive, is the necessary key equipments of a plurality of industries such as chemical industry, oil refining, light industry and the energy, and it has individual layer and multilayer two class formations.Because multi-layer structure is compared with single layer structure, not only solve heavy wall and made difficult problem, and has special advantage at aspects such as the reasonable utilization of material, Securities, thereby laminated vessel particularly multilayer HP (high pressure) vessel be widely used in the every field that process industrial produces as a kind of structural type of pressurized container.The for example ammonia convertor of chemical industry, urea synthesizer, the hydrogenator of petroleum refining, full multilayer high pressure hydrogen gas holder etc.Along with the development of science and technology, need pressurized container under the harsh conditions such as high pressure and corrosion, to work.Multilayered pressure vessel has had sound when great development at present.
But for the manufacturing of large pressurized vessel, domestic also do not have to form relevant technical specification, and abroad the prestressed pressure container all existing corresponding design code can use.Development for present energy-conserving and environment-protective district heating, large-scale district heating device is general all at the pressurized container of the above volume of 5000m3, manufacturing, installation, transportation etc. are all relatively more difficult, and in order to satisfy development need, the pressurized container of novel high-capacity becomes main direction of studying from now on.
Summary of the invention
The technical problem that solves:
Current pressurized container mostly is the integrated metal pressurized container, complicate fabrication process, and the excessive transportation difficulty that causes easily of volume, voltage endurance capability also is restricted simultaneously.For the trouble of the manufacturing that solves large pressurized vessel, transportation, installation, the utility model has been announced a kind of prestressed pressure container.
Technological scheme:
Provide following solution for solving above technical problem the utility model:
A kind of prestressed pressure container, by the axial prestress muscle, ring orientation prestress rib, the compositions such as prestressed concrete soil block, detachable concrete block is fixed into a cylindrical body by axial prestress muscle and ring orientation prestress rib, the concrete block inwall is provided with adiabator layer, the adiabator layer inwall has lining, be used for holding solution in the lining, upper end at container is provided with end cap, made things convenient for the maintenance of this tun, middle part, top and bottom are provided with leads to the outer pipeline of container, can be communicated with the turnover that realizes solution with external solution by pipeline.The concrete block axial direction is provided with a plurality of axial pre-manufactured holes, and hoop is provided with a plurality of hoop pregroove marks.The axial prestress muscle is installed in the pre-manufactured hole of concrete block, and axial prestress muscle two ends are fixed on container top and bottom by ground tackle.Ring orientation prestress rib is installed in the hoop pregroove marks of concrete block, and the ring orientation prestress rib two ends connect by ground tackle.The sealing corrosion material is arranged on axial prestress muscle and the ring orientation prestress rib.Sealing material can effectively divide the corrosion that prevents prestressed tendon, improves the working life of container.Concrete block can be made at precasting yard as required needs size, and install at the scene that then is transported to, and it is larger so just to produce volume, the large pressurized vessel of convenient installation and energy bearing certain pressure.
Beneficial effect:
This device is applicable to large pressurized vessel, adopts concrete structure, and the concrete block detachable by multistage is spliced, and avoided general large pressurized vessel complicate fabrication process, difficult; Adopted prestressed structure in the pressurized container, compared with generic container and have higher bearing capacity, more reliable performance, safety.

Embodiment
Specific embodiment
Below in conjunction with accompanying drawing this equipment is carried out following detailed description:
A kind of prestressed pressure container, by axial prestress muscle 2, ring orientation prestress rib 4, prestressed concrete soil block 3 compositions such as grade, detachable prestressed concrete soil block 3 is fixed into a cylindrical body by axial prestress muscle 2 and ring orientation prestress rib 4, prestressed concrete soil block 3 inwalls are provided with adiabator layer 5, adiabator layer 5 inwalls have lining 10, be used for holding solution in the lining 10, be provided with end cap 1 in the upper end of container, made things convenient for the maintenance of this tun, the middle part, top and bottom are provided with leads to the outer pipeline of container, and middle part pipeline 7 and upper pipe 8 all can be used for passing in and out solution.Prestressed concrete soil block 3 axial directions are provided with a plurality of axial pre-manufactured holes 12, and hoop is provided with a plurality of hoop pregroove marks 13.Axial prestress muscle 2 is installed in the pre-manufactured hole 12 of concrete block, prestressed concrete soil block 3 forms a complete cylindrical container by 2 tensions of axial prestress muscle, axial prestress muscle 2 two ends are fixed on container top and bottom by ground tackle 9, make container be subject to certain axial prestress effect by axial tightening.Ring orientation prestress rib 4 is installed in the hoop pregroove marks 13 of prestressed concrete soil block 3, and ring orientation prestress rib 4 two ends connect by ground tackle, makes container be subject to certain ring orientation prestress effect by the hoop tension.On axial prestress muscle 2 and the ring orientation prestress rib 4 the sealing corrosion material is arranged.Sealing material can effectively divide the corrosion that prevents prestressed tendon, improves the working life of container.Prestressed concrete soil block 3 can be made at precasting yard as required needs size, and install at the scene that then is transported to, and it is larger so just to produce volume, easy for installation and large pressurized vessel that can bearing certain pressure.
Lower mask body is narrated the implementation of this device:
