For achieving the above object, the present invention adopts following technical proposals: a kind ofly embrace fastener device for pipeline heating, the medium, high frequency Electromagnetic Heating that thaws, this heating is embraced fastener device and is had one and embrace button (1), embraces button (1) and is made up of two symmetrical semicircle body of stainless steel.Two symmetrical semicircle body of stainless steel connect by connecting hinge (2).Above-mentioned armful of button (1) is provided with thermal baffle (6), thermal baffle (6) is laid with high frequency coil (4); The above-mentioned armful of upper mounting temperature sensor (3) of button (1), temperature transducer (3) is for detected temperatures.Armful button (1) is provided with handle (5).
Above-mentioned armful of button (1) is connected with system control box (9) by medium, high frequency coil connecting line (8) and attachment plug (7).
During use, hold handle (5) and stainless steel symmetry armful button (1) armful is anchored on oil extraction in oil field packing or the heating object such as water filling, steam injecting pipe.Then, connect the power supply of control system, set the parameters such as temperature required, reach the oil after set temperature in heating object or ice-out, so just can reach the object of normal construction.
Beneficial effect of the present invention and feature:
1, rational in infrastructure, install, convenient disassembly, can flexibly, efficiently multiple spot use.
2, outer cover is stainless steel full weld mode, is convenient to wiping, cleaning, is beneficial to environmental protection,
Without any disposal of pollutants.
3, efficiency is high, energy-conservation, as long as generally pipeline heating within 3-5 minute, can be made to 140-150 degree, once heating is pressed 5KW and calculated general 0.2 yuan of (0.8 yuan/kilowatt hour) expense.
4, medium, high frequency heating equipment is by electromagnetism to heating liquid in iron pipe, without naked light baking, solves fire explosion hidden danger.
5., because heating equipment itself does not have action contact, so electric arc can not be produced, therefore avoid the risk that well head explodes.
6. heating equipment is made by stainless steel and insulating material, so itself is not by electromagnetic effect, does not have high temperature, and the personnel that prevent are burnt the accident such as to scald.
7. heating equipment is controlled by intelligent middle, high frequency control box, and regulation and control are to desirable control temperature.
8. heating equipment also has the functions such as pipeline of oil production preheating, flow process de-plugging, the preheating of iron liquid in pipe.
9. electromagnetic heating system is superior in quality frequently for a whole set of intelligent middle, high, and reasonable price is durable in use, light and flexible, is convenient to employee's operation, can be widely used in oil recovery, water filling, steam injection scene, be specially adapted to the maintenance in stuffing box for oil field well head winter.
