Detailed description of the invention
Now with detailed reference to embodiments of the invention, wherein one or more examples are shown in the drawings. Each example provides rather than by way of illustration as limiting.The most obvious , the present invention can be carried out various modifications and variations without deviating from the scope of the present invention or spirit. Such as, as shown in a part for an embodiment or described feature may be used for another embodiment with Produce another embodiment.Therefore, the invention is intended to covering and fall into claims and equivalent thereof Within the scope of these amendment and modification.
Seeing Fig. 1, totally illustrate heat exchanger 10, it includes housing 12 and multiple core separated Body i.e., the first core body the 16, second core body 18 and the 3rd core body 20.It is positioned at heat exchanger Multiple core bodys separated include at least two core body.Housing 12 is substantially cylindrical, in having Portion's volume 14, described housing is limited by upper side wall 22, lower wall 24 and a pair end cap 26.In order to say Bright property purpose, heat exchanger is horizontally disposed with；But, heat exchanger can be in any commercial operation mode Location, as vertically positioned.
First core body the 16, second core body the 18, the 3rd core body 20 is arranged on the internal capacity of described housing In 14, and it is partially immersed in liquid housing side liquid.In one embodiment, described liquid housing Side liquid is vaporization fluid, i.e. cold-producing medium.Liquid housing side liquid and core body side liquid with convection current or Cross-current mode flows through each core body.
Each in the plurality of core body separated receives single core body side liquid, it is allowed to liquid Indirect heat exchange simultaneously is carried out between state housing side liquid and individually core body side liquid.
One design principle of core shell-type exchangers (core-in-shell heat exchanger) is core Side fluid and liquid housing side liquid carry out cross exchange.Liquid housing side liquid is present in pressure and holds In device, brazed aluminum compact heat exchanger core body be arranged in this pressure vessel and be immersed at or approximately at In the liquid housing side liquid of boiling point.Liquid is inhaled into the bottom surface of heat exchanger, in this place, bottom surface State the hotter surface in liquid contact core body.Then, liquid housing side liquid passes through exchanger core body Passage transmission heat.The major part of heat transfer is from the latent heat of vaporization of liquid housing side liquid.Core body side Fluid is cooled or condensation along with the oncoming lane of its passage in exchanger core body.
The heat of core shell-type exchangers and hydraulic performance depend on the liquid level in exchanger.For making It is thermosyphon effect that liquid housing side liquid is recycled to the driving force of exchanger core body.Thermosyphon effect is The passive fluid transport phenomena caused by natural convection heating power.When fluid vaporization occurs, fluid is added Heat, fluid density reduces to become lighter.Along with it flows up the most in the channel, new liquid Body is inhaled into.This causes the liquid housing side liquid induced by the thermal gradient in core body to enter core passageway Natural Circulation.That the whole liquid in passage all vaporize, the mixture of liquid and vaporizer by Upper conveying is by exchanger core passageway, and discharges through the top of described core body.Above core body, must The space providing enough must be separated with liquid so that only vaporizer leaves the housing of core body for vaporizer The top section of side.Then liquid in the top section separation of exchanger be re-circulated to the end of container Portion, locates to vaporize in the core subsequently bottom this.Make upper in core shell-type exchangers of liquids and gases The driving force separated in portion's section is gravity.
By the external hydraulic pressure between the effective liquid level in core body and the liquid level outside core body The thermosyphon circulation effect that (liquid level difference) strengthens or weaken in core body.Along with the liquid liquid in housing Position declines, and reduces for the driving force making liquid transfer in exchanger core body, and effectively heat Transmission reduces.When liquid level drops below core body, owing to losing thermosyphon effect This causes heat transfer to be lost, and the circulation of liquid housing side liquid stops.If heat exchanger is higher than core body Run under the liquid level of (being filled with), then the heat transmitted weakens further, this is because core The vaporizer produced in body must pull against extra head to escape from core body.More serious situation is liquid Body fluid position is less than exchanger core body, because this makes heat transfer be reduced to close to zero.
As it was previously stated, in heat exchanger vaporization fluid rock stability and the control that can affect exchanger Property processed.Additionally, the cyclic attributes of motion will cause the cyclic behaviour of heat transference efficiency, and therefore lead Cause the cyclic behaviour of the process conditions of LNG liquefaction plant.These unstability are likely to result in poor Overall factory performance, and cause narrower work/use state range.
The Sloshing suppression baffle plate of the present invention decreases the motion impact on core shell-type exchangers.Rock and press down Baffle plate processed is positioned in the internal capacity of housing, in order to separate multiple core body separated.Each rocking is pressed down Baffle plate processed allows liquid housing side liquid to be limitedly distributed between each core body.Sloshing suppression baffle plate is permissible Bear low temperature.Sloshing suppression baffle plate can bear the flowing of the liquid housing side liquid between each core body And described flowing can be made to change direction.
Seeing Fig. 2, Sloshing suppression baffle plate 28 is solid slab, to provide the liquid in heat exchanger 10 Rocking of the minimizing of housing side liquid.The Sloshing suppression baffle plate 28 of solid slab includes in the bottom of baffle plate using In allowing the limited opening being distributed between core body of liquid housing side liquid.Solid slab Sloshing suppression baffle plate 28 depend highly on intended movement degree.In an embodiment, the height of solid slab motion suppression baffle plate Spend the top at or close to core component.Due to the motion increased in the bottom of core body with formed Potential impact to thermosyphon effect, so the placement of baffle plate and size are crucial.In order to ensure not Weakening thermosyphon effect, the size of opening is crucial.
Seeing Fig. 3, Sloshing suppression baffle plate 30 is perforated plate, and it is positioned at the central section of core body with suppression The impact of motion.In an embodiment, perforated plate Sloshing suppression baffle plate is single plate.In another embodiment In, perforated plate Sloshing suppression is double plates with consistent hole.In the case of double plates, described vapour Change liquid and must change direction further slow-down with by second plate.Between each core body also Draw out solid slab Sloshing suppression baffle plate 28.This embodiment makes liquid more uniformly be distributed, to core body Following motion has less impact, and has the impact of minimum to thermal siphon.
Seeing Fig. 4, Sloshing suppression baffle plate 32,34,36,38,40 and 42 is positioned at each core assembly Edge.Sloshing suppression baffle plate can be solid slab, perforated plate or combinations thereof.In an embodiment, Region between each core assembly is empty.In another embodiment, the region between each core assembly is filled out It is filled with packing material in order to suppress flow motion.
Seeing Fig. 5, Sloshing suppression baffle plate is horizontally mounted between core body dynamic with guarantee to reduce upwards Amount.Sloshing suppression baffle plate can be solid slab, perforated plate or combinations thereof.
See Fig. 6, in order to reduce this surge movement of surge movement on the top of core body by because of Upwards raise for liquid and enter into vaporizer separated space and cause potential too much liquid entrainment, institute With by angled or be placed on the top of core component or near core body through the Sloshing suppression baffle plate of rounding The top of assembly, leaves the top of core component in order to reboot liquid.
Described any independent or combination Sloshing suppression baffle plate may serve to efficiently and effectively Reduce the motion impact on heat exchanger.
In addition to motion suppression baffle plate is set, be suitable to the certain form of filling material of low temperature service Expect such as stainless steel structure or random packing material can also add the sky in housing to In gap space, in order to suppress motion.Unlikely can carry for structured or random filling individually For enough pressure drop with the momentum of the moving fluid that slows down, but it can be used in combination with baffle plate to provide motion Inhibitory action.
Because these exchangers are the longest, so core shell formula can also be handed over by the least surge movement The performance of parallel operation produces dramatic impact.Narrow working range result in the sensitivity to fluctuation.Pass through Placement to hypokinesia baffle plate thinks over, it is possible to produce the core shell formula heat of compact design is handed over Parallel operation is in order to work in movement environment, and can avoid using the replacement of image tube shell-type exchangers Thing, and then save great amount of cost.
