Description
Technical field
The utility model relates to the crude oil gathering line, particularly oil field ground pipeline solar energy frozen soil layer defroster.
Background technology
In the crude oil gathering engineering, the most of buried-pipe laying of gathering line.In northern oil field, gathering line is different buried below frozen soil layer according to the region, and the parts on the pipeline also are embedded in underground.In addition, stop up, regularly in petroleum pipeline, throw ball in the Crude Oil Transportation in order to wax removal for preventing the petroleum pipeline wax deposition.
In the winter time, when wax deposition is very thick, the wax dirt that the wax removal ball scrapes off on the tube wall under the oil pipe internal pressure promotes is gone on foot along line downstream, the wax in wax removal ball downstream is cumulative, because blocking up and the resistance of pipeline of wax to the wax removal ball, arrive the pipeline corner in the migration of wax removal ball, resistance increases, the motionless wax removal ball that again pushes away the pressure of pipeline upstream continues to walk about along line downstream, at this moment will cause pipeline to stop up, unique way of handling this obstruction is that excavation frozen soil exposes obstruction place pipeline, joins steam coach steam-jet siphon linearize wax de-plugging then.
Summary of the invention
The purpose of this utility model provides a kind of oil field ground pipeline solar energy frozen soil layer defroster that makes things convenient for maintenance in winter excavation
The purpose of this utility model is achieved in that oil field ground pipeline solar energy frozen soil layer defroster, it is characterized in that: pipe and outer tube sleeve form together in comprising, outer tube and interior effective fixed support bar welding support fixation are integral; Interior length of tube is greater than outer length of tube; Interior pipe stretches to the length of outer tube between 700-800mm; Interior pipe stretches out the length of outer tube greater than 1000mm, and outer tube and interior pipe are vertically fixed on underground together, and the outer tube other end is above ground level.
Described outer tube diameter is 900-1100mm, and diameter of inner pipe is 700-900mm, and ring spacing is 100-200mm between pipe.
The utility model has the advantages that: utilize solar energy to reduce northern oil field pipe and bury the ground parts degree of depth of frozen soil layer on every side, excavation frozen soil layer workload reduced when keeped in repair winter, brought convenience for maintenance, maintenance.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: 1, outer tube; 2, interior pipe; 3, fixed support bar; 4, face of land convective air flow to; 5, interior pipe convection current air outgoing stream to; 6, ground.
The specific embodiment
As shown in Figure 1, oil field ground pipeline solar energy frozen soil layer defroster, pipe 2 and outer tube 1 sleeve form together in comprising, and outer tube 1 and interior pipe 2 usefulness fixed support bars 3 welding support fixation are integral; Interior pipe 2 length are greater than outer tube 1 length; Interior pipe 2 stretches to the length of outer tube 1 between 700-800mm; Interior pipe 2 length of stretching out outer tube 1 are greater than 1000mm, and outer tube 1 and interior pipe 2 are vertically fixed on ground 6 times together, outer tube 1 other end above ground level 6.Outer tube 1 diameter is 900-1100mm, and interior pipe 2 diameters are 700-900mm, and ring spacing is about 100-200mm between pipe.
Operating principle of the present utility model is: winter north dryness of air, surface soil most of the time place's dry state, because dry soil conducts heat slow, the energy of solar radiation in daytime can produce 20～30 ℃ surface temperature on the topsoil of ground, skim air on this temperature heating contact face of land, and overhead high more, air themperature is low more.
Now get three temperature values and describe its operating principle.Pipe 2 tip temperature are T1 in the solar energy heat-transferring device, and place, face of land temperature is T2, and it is T3 that inner and outer pipes is imbedded underground bottom temp.In the winter time, the air themperature that is higher than place, the face of land is very low, the relation of T1＜T3 is set up generally speaking, it is poor that this temperature difference produces atmospheric density, in the solar energy heat-transferring device, produce siphonage, the skim hot air is flowed out from interior pipe 2 tops behind pipe 2 bottoms in entering by the inner and outer pipes ring spacing, airflow direction see in the accompanying drawing face of land convective air flow to 4, interior pipe convection current air outgoing stream is to the flow directions of 5 marks and the direction of arrow in the inner and outer pipes.Hot air is cooled in this heat transfer unit (HTU) bottom, and the steam that carries in the air is emitted heat in pipe end condensation, and the soil layer around this device is produced antifreezing effect.At night or cloudy day, surface temperature is low, and the relation of T1＜T3 is also set up, also can produce siphon, what heat transfer unit (HTU) was advanced in siphon at this moment is cold air, and cold air does not produce condensed water in heat transfer unit (HTU) pipe bottom, and only will manage end local cooling, very fast this siphon just is stopped.For whole winter, the most of the time is fine, and this device imports the heat that underground heat is long-range and derive, and is the frozen soil layer attenuation around it, brings convenience for the above-mentioned excavation that needs repairing.
