Description

The jacketed pipe attemperator of cryogenic liquid
Technical field
The utility model relates to a kind of jacketed pipe attemperator of cryogenic liquid, be suitable for chemical industry equipment, LNG device, The outer cryogenic liquid of the ice chest of air separation plant and liquefying plant keeps the temperature pattern, belongs to cryogenic liquid heat preservation technology field.
Background technique
In air separation unit, cryogenic liquid product outlet temperature is extremely low, and general operation temperature can reach -196 DEG C or less.It is transporting During row, the outer low-temperature liquid pipe of ice chest is very easy to run cold, extension frost, causes the loss of energy consumption.Especially occur in recent years Air separation unit product Internal-compression flow, device can generate a large amount of cryogenic liquid product, and cryogenic liquid product generally all passes through Foamed heat insulating pipeline or vacuum tube are transported in storage tank or tank car.Both mode of movement have respective disadvantage in practice End: heat preservation required for foamed heat insulating pipeline is oversized, is not easy to general layout, outer layer cracky, failure, later maintenance at This height;Vacuum tube purchase cost is high, and tube wall vacuum degree can gradually decrease at any time, is easy to run cold extension frost, and every segment pipe connects 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.
