There is dead zone at the place of connecing, for having the risk of hydrocarbon aggregation in liquid oxygen pipeline.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and a kind of structure provided is simple, safety
Reliably, rationally efficiently, be convenient for personnel's operation and maintenance, can effectively, stablize transporting low temperature liquid product, reach reliable Low Temperature Liquid
Body pipe insulation effect, and the jacketed pipe attemperator of the cryogenic liquid of unobstructive.
The utility model is completed by following technical solution: a kind of jacketed pipe attemperator of cryogenic liquid, it leads
There is upper and lower two halves heat preservation cylinder to form by the connecting flange flanging welded among cylinder, is provided in the heat-preservation cylinder body
The pipeline support frame for supporting and fixing for low-temperature liquid pipe supports low-temperature liquid pipe in heat-preservation cylinder, and is allowed to fixed
Vibration is not generated, is allowed heat-preservation cylinder and inner cryogenic pipeline to be integrally formed, is synchronized and strengthen heat-preservation cylinder and low-temperature liquid pipe rigidity；
Be provided with sand loading hole at the top of heat preservation cylinder, bottom is provided with clearance hole, and be filled with heat-insulating material in heat-preservation cylinder body；
Sand loading hole is located at heat-preservation cylinder high point, since pearlife has extraordinary mobility, is allowed to evenly laid out in cylinder, no dead angle,
It is not in the case where empty cylinder is without heat preservation；Bottom clearance hole is convenient for letting out sand, maintenance internal pipeline.
As preferred: the heat preservation cylinder is formed by multistage cylinder by connecting the flange flanging welded of end edge；It is described
Low-temperature liquid pipe by anchor ear be fixed on it is described be horizontally arranged on the pipeline support frame between cylinder, and be provided in every section of cylinder
2-3 pipeline support frame；The heat-insulating material selects pearlife.
The utility model has structure simple, safe and reliable, rationally efficient, safeguards convenient for personnel, is able to maintain air separation unit
Or LNG device low energy consumption and even running the features such as.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A direction view of Fig. 1.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: Fig. 1, shown in 2, one kind described in the utility model
The jacketed pipe attemperator of cryogenic liquid, it mainly has upper and lower two halves heat preservation cylinder to weld by the connecting flange flange 7 among cylinder
It connects, the pipeline support frame 3 for supporting and fixing for low-temperature liquid pipe 2 is provided in the heat preservation cylinder 1, is being protected
Be provided with sand loading hole 4 at the top of warm cylinder 1, bottom is provided with clearance hole 5, and heat preservation cylinder 1 in be filled with heat-insulating material.
As shown in the figure, the heat preservation cylinder 1 is welded by multistage cylinder by the flange flange 7 of connection end edge；Institute
It states low-temperature liquid pipe 2 to be fixed on the pipeline support frame 3 being horizontally arranged between cylinder by anchor ear 6, and in every section of cylinder
It is provided with 2-3 pipeline support frame 3；The heat-insulating material selects pearlife.
Embodiment: the utility model forms closed cavity by the heat-preservation cylinder of low-temperature liquid pipe outer layer, inside fills pearlife
Carry out adiabatic heat-insulation.Thermal insulation material-pearlife have good fluidity, thermal coefficient is low, chemical stability is good, non-ignitable, nontoxic, nothing
The characteristics such as taste, sound-absorbing are splendid exhausted temperature cold insulation materials.Using the higher pearlife of adiabatic coefficent replace traditional glass block or
Foaming agent can substantially reduce low-temperature liquid pipe heat preservation size, reduce heat preservation cost, improve pipe insulation effect as heat-insulating material
Fruit.Meanwhile the good acoustical absorbance properties of pearlife, it helps reduce noise caused by fluids within pipes conveying, reach noise reduction
Purpose.
Heat preservation cylinder described in the utility model is upper and lower two halves formula, respectively independent production, is welded among cylinder using flange
Direct type formula will not reveal pearlife；Two heat-preservation cylinder linked vector graphs are also flanging welded.Full section using welding pattern, have it is reliable,
Safety, without leak source, be easily installed the characteristics of.Meanwhile the moisture in atmosphere will not penetrate into the insulation barrel of low temperature, will not make pearl
Light sand gets damp failure, has high reliability.Two halves formula insulation barrel is unanimous between the higher and lower levels, is also convenient for batch machining production.
The top for keeping the temperature cylinder is equipped with sand loading hole, and bottom is equipped with clearance hole.Its role is to sand loadings and later maintenance to let out sand.
Sand loading hole is located at heat-preservation cylinder high point,, can be evenly laid out in cylinder after filling pearlife since pearlife has good mobility,
It is not in the case where empty cylinder is without heat preservation without dead angle；Bottom clearance hole is convenient for letting out sand, maintenance internal pipeline.
The inside for keeping the temperature cylinder is equipped with pipeline support.Each section band 2-3 part, is used to support cryogenic liquid pipe in heat-preservation cylinder
Road is allowed to fixed, does not generate vibration, allows heat-preservation cylinder and internal liquid pipeline to be integrally formed, synchronize and strengthen heat-preservation cylinder and pipeline
Rigidity.The design of integral type is also beneficial to reduce heat preservation barrel thickness, mitigates a whole set of heat preservation weight, it is corresponding reduce piping lane load and
Reduce cost of manufacture.
Sand loading hole is arranged in the top of the heat preservation cylinder, it may have the effect of inspection hole cannot be only used for one-time pad
Pearlife, it can also be used to cryogenic piping or pearlife aridity and flatness in subsequent examination cylinder.The heat insulation effect of package unit,
Depending on the aridity of pearlife product quality and pearlife, pearlife after dampness, heat insulation effect can sharply decline, cryotronl
Road meeting outer layer can hang frost, failure, largely run cold.In certain extreme cases, cold air can be conducted to piping lane, the pipe of carbon steel material
Corridor has cold brittleness, may bursting by freezing piping lane profile when serious.Extremely convenient inspection hole, can effectively prevent the hair of this phenomenon
It is raw.
