Abstract
The utility model relates to a kind of atmospheric and vacuum distillation unit transfer line with the cold tight setting of two-stage, comprise process furnace, transfer line high-velocity tube, transfer line low speed pipe, vacuum distillation tower, constant force spring and support, wherein, transfer line is between process furnace and vacuum distillation tower, constant force spring is placed between transfer line high-velocity tube and low speed pipe, cold tight design is carried out respectively in vacuum distillation tower ingress and furnace outlet place, and in furnace outlet fragment position, boiler tube drag hook is removed, this a part of boiler tube is made to become a part for transfer line, and then the swell increment of whole transfer line system can be shared.The utility model utilizes the cold tight design of two-stage, whole system is made not need oversize straight tube to compensate the displacement of transfer line, and in the use procedure of whole transfer line, it is very little that pressure drop reduces, good effect is served to the smooth running of system, after being calculated by Stress Analysis Software CAESAR II, stress conformance with standard code requirement, this security of system is reliable.
Description
Technical field
The utility model relates to a kind of atmospheric and vacuum distillation unit transfer line with the cold tight setting of two-stage.
Background technology
Pressure-reducing line for oil-transferring is the core of atmospheric and vacuum distillation unit, is process furnace delivery technology material the only way which must be passed to vacuum still, and therefore, the quality of its design directly affects the quality product of vacuum distillation tower and the extracting rate of vacuum distillation tower.
Generally, the design of transfer line will consider the factors such as character and flow velocity, the actual state of erecting stage, the economic input of developer of the configuration of process furnace and installing space, medium.And the Atmospheric vacuum transfer line device designed both at home and abroad is generally in order to fully absorb the swell increment and pressure drop that transfer line low speed segment brings, between furnace outlet section to transfer line high regime, a large amount of U-shaped coil pipes must be installed, the length also unusual length of transfer line design, design although it is so produces a desired effect, also ensure that the extracting rate that vacuum distillation tower is higher, but necessary impact is brought on the economic input of whole device and engineering time and energy, be not suitable for very much being applied in process furnace installing space limited, when scene does not have a unnecessary space, place.
Summary of the invention
The utility model is for above-mentioned deficiency of the prior art, a kind of atmospheric and vacuum distillation unit transfer line with the cold tight setting of two-stage is provided, utilize cold tight design, the straight tube making whole system not need so to grow is to compensate the displacement of transfer line, and in the use procedure of whole transfer line, it is very little that pressure drop reduces, good effect is served to the smooth running of system, after being calculated by Stress Analysis Software CAESAR II, stress conformance with standard code requirement, this security of system is reliable.
The technical solution of the utility model is as follows: a kind of atmospheric and vacuum distillation unit transfer line with the cold tight setting of two-stage, comprises process furnace (1), constant force spring (2), transfer line high-velocity tube (3), support (4), transfer line low speed pipe (5) and vacuum distillation tower (6); Wherein, described two-stage is cold is tightly separately positioned on the exit of process furnace and the ingress of vacuum distillation tower; Described constant force spring is placed between transfer line high-velocity tube and low speed pipe, and dispersed arrangement; Cold tight design between described furnace outlet place and transfer line high regime, the distance stretched downwards is generally 30% ~ 70% of coil outlet place swell increment and 2% ~ 20% of transfer line high regime length; Described vacuum still ingress and transfer line low speed segment between cold tight design, the distance stretched to the right is generally 40% ~ 75% of transfer line low speed segment swell increment and 3% ~ 30% of transfer line high regime length; Boiler tube drag hook removes by described furnace outlet fragment position, makes this part of boiler tube become a part for transfer line; Described support is roller support, and distance transfer line high-velocity tube 1-5m; Do not need between described furnace outlet section to transfer line high regime a large amount of U-shaped coil pipes is installed, save space and economy.
The utility model can realize following effect:
1., by boiler tube drag hook being removed in furnace outlet fragment position, making this part of boiler tube become a part for transfer line, and then the swell increment of whole transfer line system can be shared;
2., by settling 3 constant force springs between transfer line high-velocity tube and low speed pipe, serve the effect supporting transfer line high-velocity tube and reduce mouth of pipe pressure;
3. utilize cold tight design, the straight tube making whole system not need so to grow is to compensate the displacement of transfer line, and in the use procedure of whole transfer line, it is very little that pressure drop reduces, and serves good effect to the smooth running of system;
4. after being calculated by Stress Analysis Software CAESAR II, stress conformance with standard code requirement, this security of system is reliable;
5. do not need, between furnace outlet section to transfer line high regime, a large amount of U-shaped coil pipes is installed, save space and economy, be highly suitable for process furnace installing space limited, when scene does not have a unnecessary space, place.
