Abstract
The utility model relates to a device for heating pipeline using skin current. The utility model mainly adopts the method of cathode protection and sacrificed anode. Moreover, a skin pipe is provided with a special skin pipe joint. Therefore, the anticorrosion property of an oil pipe is increased, and the phenomena created by local overheating are avoided. Thus, the device is more reasonable and practical.
Description
The utility model relates to a kind of pipeline skin current heating equipment, relates to the pipeline heating equipment of oil movement and storage industry or rather.
At present, at home and abroad the oil movement and storage industry generally adopts skin current heating for oil transport pipeline because this mode of heating has efficiently, safety, reliably and its device proper have characteristics such as explosion prevention function, thereby be widely adopted.But therefore currently used skin current heating equipment causes problems such as the not enough constant temperature of heating also having certain defective aspect companion's heat of the Overheating Treatment of piecing devices, cathodic protection pipe, the electrical leakage voltage processing and to the anticorrosion problem of oil transport pipeline.
The purpose of this utility model is exactly the shortcoming that overcomes above-mentioned skin current heating equipment, and a kind of novel pipeline skin current heating equipment is provided, thereby has solved the problems such as electrical leakage voltage of the overheated and device in the anticorrosion and joint of oil transport pipeline.
The purpose of this utility model realizes that by following proposal pipeline skin current heating equipment of the present utility model comprises an oil transport pipeline (being also referred to as medium tube).Pipe ends portion is provided with the valve that links to each other with other pipeline, in the pipeline outside thermal insulation layer is arranged, between pipeline and thermal insulation layer, be provided with companion's heat collection skin pipe that a magnetic material is made, be provided with heat-resisting cable in companion's heat collection skin pipe, the pressure relief line joint is arranged on the termination exterior wall of collection skin pipe, companion's heat collection skin pipe and oil transport pipeline are solidly installed by solid card, equidistant some temperature measuring tubes that are provided with on oil transport pipeline, it is characterized in that, on oil transport pipeline, be provided with a negative contact, this negative contact is connected in the negative electrode of a direct current potentiostat by the cathodic protection cable, and described direct current potentiostat is connected in by lead and buries on the ground anode assembly; Respectively be provided with a kind ofly by the magnetic short tube at the two ends of above-mentioned companion heat collection skin pipe, the special skin pipe joint that copper pipe and convex surface line terminals constitute, this joint are to settle like this, and one of adaptor spool be a silk mouth pipe joint, and other end and copper pipe socket-connect.Copper pipe adopts the interference hot extrusion and is installed in companion's heat collection skin pipe short tube, and copper pipe one end is the convex surface line terminals; The Ac of an output terminal output of one adjustable transformer passes from collection skin pipe by the special skin pipe joint of heat-resisting cable through collection skin pipe head end place, is connected and is connected in the end of collection skin pipe with the joint at the other end place of collection skin pipe, another output terminal of adjustable transformer is directly connected in companion's heat and is collected skin pipe head end.
Advantage of the present utility model is owing to make to be oil transport pipeline into negative electrode, current potential passes through the earth soil from anode assembly, constitute total loop with negative electrode, forcing to form anode material is corroded, thereby prevented the corrosion of oil transport pipeline, in addition because the skin pipe joint place has adopted the pipe-in-pipe structure, can be according to the needs of on-the-spot and environment and arbitrarily installation, and kept good contact to make local contact resistance little, the generation of having stopped local superheating.
Further describe an embodiment of the present utility model below in conjunction with accompanying drawing;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the joint structure schematic representation of collection skin pipe.
Now referring to accompanying drawing 1, pipeline skin current heating equipment comprises an oil transport pipeline 4 (also claiming medium tube), the two ends of pipeline 4 are provided with the valve 1 that links to each other with other pipeline, in oil transport pipeline 4 outsides thermal insulation layer 3 is arranged, between pipeline and thermal insulation layer, be provided with companion's heat collection skin pipe 6 that a magnetic material is made, be provided with heat-resisting cable 7 in companion's heat collection skin pipe 6, pressure relief line joint 10 is arranged on the termination outer wall of collection skin pipe, companion's heat collection skin pipe 6 is solidly installed by blocking 9 admittedly with oil transport pipeline 4, at oil transport pipeline 4 temperature measuring tube 2 can be set according to actual needs, above-mentioned companion's heat collection skin pipe 6 can connect by collection skin pipe thread mouth pipe joint 8 according to the length needs of actual conditions, on oil transport pipeline 4, be provided with a negative contact 15, this negative contact 15 connects the negative electrode (seeing diagram) of a direct current potentiostat 12 by protecting cable, and the output anode of described direct current potentiostat 12 is connected in by lead and buries on the ground anode assembly 13; Respectively be provided with a kind of short tube and special skin pipe joint 5 of constituting of copper pipe 16 and convex surface line terminals by a headband silk mouth at the two ends of above-mentioned companion heat collection skin pipe 6, the copper pipe 16 of this joint 5 adopts the interference hot extrusion and is installed in companion's heat collection skin pipe short tube 6, and copper pipe 16 1 ends are convex surface line terminals 17.One adjustable transformer 11, the Ac of an output terminal output passes from collection skin pipe by the special skin pipe joint 5 of heat-resisting cable 7 through the head end place of collection skin pipe 6, the joint 5 at the other end place of collection skin pipe 6 connects and is connected in the end of collection skin pipe 6, another output terminal of adjustable transformer is directly connected in head end companion heat collection skin pipe 6, forms the Ac loop.After the energising, produce Skin effect, because the iron loss (producing magnetic hysteresis and eddy current) of collection skin pipe and the copper loss of heat-resisting cable make whole collection skin pipe 6 become heater, collection skin pipe 6 is directly supplied with oil transport pipeline 4 with heat.The described ground anode assembly 13 that buries is made row's assembly for steel, aluminium, magnesium alloy materials.Generally speaking, the hot length of the companion of oil transport pipeline 4 is advisable with interior with 5000m, and the specification of companion's heat collection skin pipe is the magnetic tube of φ 27-46 * 3.2-4mm.
