Description
Technical Field
The utility model relates to an oil field equipment, concretely relates to well head heating device with explosion-proof function.
Background
When the temperature of an oil extraction site is low, particularly in winter, the viscosity of fluid in a pipeline is increased, the flow rate is seriously influenced, and the currently adopted electric heater mainly adopts an electric heating pipe to directly contact with oil for heat exchange, but the electric heater is difficult to popularize in a large range in production due to short service life. According to field investigation, the electric heater is easy to scale, the electric heating pipe is easy to damage, the power consumption is large, the safety is poor, the electric heating pipe needs to be replaced about half a year, and the service life is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a long service life, safe energy-conserving well head heating device who has explosion-proof function to the defect that prior art exists exactly.
The technical scheme is as follows: the utility model provides a well head heating device with explosion-proof function, including the inner tube, the upper and lower both ends of inner tube are equipped with the one end of seamless steel pipe through oval head sealing connection respectively, the other end connection of seamless steel pipe is equipped with the flange, the periphery of inner tube is equipped with the urceolus, the inner tube passes through the shrouding with the urceolus and is connected sealedly, form hollow space between inner tube and the urceolus, be equipped with explosion-proof power source on the urceolus, the outer wall winding of inner tube has the heater strip, the heater strip electricity is connected to explosion-proof power source, still be equipped with high accuracy monomer valve.
The heating wires are silver-plated nickel-chromium alloy heating wires which are uniformly distributed on the high-frequency magnetic intermediate body in an inserting mode.
Expanded perlite is filled in a hollow space formed between the inner cylinder and the outer cylinder, and high-temperature high-purity nitrogen is used for replacement to ensure that no water molecules exist in the middle of the inner cylinder and the outer cylinder, so that the radiation heating effect and the thermal efficiency of the intermediate heating body are ensured.
Compared with the prior art, the utility model, have following advantage: the heating device adopts the silver-plated nickel-chromium alloy heating wire for heating to conduct heat conduction, and simultaneously can form a magnetic field for radiation heating, thereby saving electric energy; expanded perlite is filled in a hollow space formed between the inner cylinder and the outer cylinder, and high-temperature high-purity nitrogen is used for replacement to ensure that no water molecules exist in the middle of the inner cylinder and the outer cylinder, so that the radiation heating effect and the heat efficiency of an intermediate heating body are ensured; the device avoids contact heating with oil, is safe and explosion-proof, has reliable work, long service life, firmness and durability, and has the advantages of flexible installation, high temperature resistance, fast heat transfer, good insulation, no limitation of model and specification size in manufacturing and the like.

Detailed Description
Referring to fig. 1, a well head heating device with explosion-proof function, including inner tube 1, the upper and lower both ends of inner tube 1 are equipped with seamless steel pipe 3's one end through oval head 2 sealing connection respectively, seamless steel pipe 3's other end is connected and is equipped with flange 4, the periphery of inner tube 1 is equipped with urceolus 7, inner tube 1 is connected sealedly through shrouding 5 with urceolus 7, form hollow space between inner tube 1 and the urceolus 7, be equipped with explosion-proof power source interface 6 on the urceolus 7, the outer wall winding of inner tube 1 has heater strip 10, heater strip 10 electricity is connected to explosion-proof power source interface 6, still be equipped with high accuracy monoblock valve 8 on the section of thick bamboo wall of urc.
The heating wire 10 is a silver-plated nichrome heating wire, and the silver-plated nichrome heating wire is uniformly distributed on the high-frequency magnetic intermediate in an inserting manner.
Expanded perlite is filled in a hollow space formed between the inner cylinder 1 and the outer cylinder 7, and high-temperature high-purity nitrogen is used for replacement.
The working principle is as follows: through flange 4 and well head oil piping connection of heating device lower extreme, the heating device upper end is connected to output oil pipe through flange 4, carries out the evacuation through high accuracy monoblock valve 8 and handles the pressurize and stop the heat and run off, and with 6 circular telegrams of explosion-proof power source interface, fluid flows through the snakelike updraft of baffle 9 from bottom to top in inner tube 1, flows through the top after the heating.
