Description
Technical field
The utility model relates to a kind of novel and multifunctional air cooling heat exchangers.
Background technique
At present during viscous crude production and transport, the oil that needs to come transport by three phase separator when reaching treating stations
Air water carries out separating treatment, but due in fluid vapor (steam) temperature it is excessively high, need to carry out it heat exchange processing, it is conventional board-like and
Pipe heat exchanger heat exchange efficiency is low, cannot reach required heat transfer effect well, need to be replaced frequently maintenance heat exchanger.
Summary of the invention
The purpose of this utility model is to provide a kind of novel and multifunctional air cooling heat exchangers, and heat exchange efficiency is high, heat transfer effect
It is good, it is easy to use.
The purpose of this utility model is achieved in that a kind of novel and multifunctional air cooling heat exchanger, including with steam into
Port and the heat exchanger body of steam gas outlet, three-dimensional rib heat-dissipating pipe is arranged in horizontal uniformly distributed interval in heat exchanger body, steams
Vapour passes through three-dimensional rib heat-dissipating pipe flowing, and heat radiation air outlet grid, the bottom of heat exchanger body is arranged on the top surface of heat exchanger body
One blower is set at face, and heat dissipation air outlet grid is arranged in the air inlet of blower, and blower pushes air-flow to pass through heat exchanger
Intrinsic three-dimensional rib heat-dissipating pipe is discharged by heat radiation air outlet grid；Uniformly interval is set on the tube wall outer peripheral edge of three-dimensional rib heat-dissipating pipe
The radiating fin with heat-dissipating pipe axis perpendicular is set, radiating fin is located on the elongated end end face in three-dimensional rib heat-dissipating pipe staggeredly
Steam passage holes are arranged in interval.
This novel and multifunctional air cooling heat exchanger is mounted on separator outlet to exchange heat to the steam separated
Cooling processing.It allows the steam of separator to be condensed by level-one three-dimensional ribbed pipe first, makes steam quick in three-dimensional internal-rib pipe
The temperature of steam, is down to condensing state by diffusion, can pass through internally finned tube with condensed water every the oil in firmly steam by fin
It back flows back into system.
Working principle: steam is diffused heat exchange by a large amount of three-dimensional internal-rib pipe inner tube in uphill process, in three-dimensional
Ribbed pipe outer tube opens wide completely to be radiated by the natural air cooled steam to inner tube there.
Field experiment statistics indicate that: under conventional weather vapor (steam) temperature handle 100 ~ 105 DEG C, temperature can after heat exchange is handled
Drop to 58 ~ 63 DEG C；Temperature reaches 70 ~ 73 DEG C after conventional heat transfer is handled under hot weather.
Exchange heat super-strengthening mechanism:
Extended surface: installing rib additional inside and outside heat exchanger tube, improves the effective heat exchange area in unit volume, promotes heat exchange
The heat exchange efficiency of equipment.
Reinforce disturbance: each fin is exactly an independent disturbance member, can generate strong disturbance, reach flow regime and fill
Divide turbulent flow, be greatly thinned the thickness in boundary layer, promotes heat transfer intensity.
Intercostal accelerates: the discontinuous fin circumferentially arranged reduces the valid circulation area of fluid.Flow velocity increases, can
It realizes and boundary layer thickness is thinned, reduce thermal resistance.
The vibration principle of expansion-contraction pipe: alternate " expansion-contraction " makes fluid generate pulsation and vibration, increases fluid
Turbulent fluctuation degree, enhances heat convection.
Repetition is washed away: the TRANSFER BY PULSATING FLOW à formation of discontinuous rib à fluid is washed away repeatedly, is destroyed laminar flow layer, is reduced thermal resistance,
Near wall temperature gradient increases.
Increase tracheid shape properties: roughness differs greatly between the surface and initial surface after processing；Finished surface itself
Roughness is also larger, increases heat transfer effect.
Anticorrosive super-strengthening:
Theoretical heat exchanger tube wall temperature is high: without the hot and cold alternation process of rotary heat-transfer surface, heat-transfer surface tube wall temperature is located always
In higher temperature.
Fume side arranges three-dimensional rib plate, carries out enhanced heat transfer, and air side heat exchange is not strengthened, and is remarkably improved fume side metal
Wall temperature avoids corrosion temperature.
Flying dust is caused to adsorb SO3Ability is strong: disturbance of the rib to air-flow causes local eddy currents, so that gas containing acid fume and flying dust
There is longer time of contact, and then formed using ash particle as the absorbing unit of core, sufficiently adsorbs the SO in flue gas3, also just make
Obtain the corrosion of flue gas exchange heat pipe body.
Anti- dust stratification super-strengthening:
Trailing vortex flow-disturbing is eliminated: ribbed pipe can effectively eliminate the flow-disturbing trailing vortex that fluid flows through heat-transfer surface inside and outside three-dimensional, pass through simultaneously
Intercostal air-flow accelerates, so that flying dust is not isolated with primary air, flying dust is good with primary air followability.
The pipe surface black dirt sheeting that exchanges heat is eliminated: rib spacing is small, rib is high small, and heat exchange pipe surface is directly made to form multiple small stress
Area, even if dust stratification, can also be blown down easily so that surface should not form black dirt sheeting.
Wear-resistant super-strengthening:
Entry-end effect is eliminated: air-flow, due to the effect of internal-rib, substantially eliminates the entrance effect of light pipe when entering in heat exchanger tube
It answers, so that entrance abrasion mitigates.
Flow velocity is small between heat-transfer surface: since heat exchange property is strong, anticorrosive, anti-Soot Performance is strong, so flow velocity can between heat-transfer surface
With the smaller of choosing, this is but also ribbed pipe heat exchanger has stronger wear resistance inside and outside three-dimensional.
Slight drag super-strengthening, long-life super-strengthening:
Existing achievement proves, under equivalent arrangements steric requirements, resistance of the ribbed pipe heat exchanger compared with usual heat exchanger inside and outside three-dimensional
Reduce 10% or more.
Existing achievement proves that under the conditions of same fire coal sulphur content (4.5% or so), ribbed pipe heat exchanger (GGH) is continuous inside and outside three-dimensional
Phenomena such as runing time is more than 6 years, and burn into dust stratification, blocking do not occur.
After use: fin does not have obvious fouling phenomenon, and the sulfide moisture condensation in steam does not cause the bonding on tube wall.
