Abstract
A heating device for a buried pipeline mainly solves the problems that the exiting heating equipment is high in energy consumption, unsafe and inconvenient in mounting. The heating device is characterized in that a heating wire (2) is wound on the exterior of a heat conducting pipe (1), a heat insulation layer (3) is arranged on the exterior of the heating wire (2), an airtight protective sheath is arranged on the exterior of the heat insulation layer (3), and an airtight wire connector (5) is arranged on the exterior of the protective sheath (4). The heating device for the buried pipeline has the characteristics of safety, reliability, convenience in mounting and energy conservation.
Description
Technical field
The utility model relates to the heating plant that a kind of oil field gathering and transportation pipeline is used, especially the buried pipe heating equipment.
Background technique
The oil recovery field in the oil field need be passed to multi-purpose station with the Jing Yeji of down-hole extraction.In order to prevent that well liquid solidifies and freezes in the defeated process of collection, need be defeated to well liquid heating collection with heating plant.And existing heating plant is because reasons in structure exists the energy consumption height, dangerous with inconvenient problem is installed, the defeated effect of influence collection.
Summary of the invention
High in order to solve existing heating plant energy consumption, dangerous with inconvenient problem is installed.The utility model provides a kind of buried pipe heating equipment.This buried pipe heating equipment has safe and reliable, easy for installation and energy-conservation characteristics.
The technological scheme of the utility model is: this buried pipe heating equipment comprises heat conductive tube.Heat conductive tube is wound with heater wire outward, and heater wire has thermal insulation layer outward, and thermal insulation layer has airtight protecting cover outward, and protecting cover has airtight jointer outward.
There is flange at heat conductive tube two ends in the such scheme.
The utlity model has following beneficial effect: this buried pipe heating equipment is owing to adopt heat conductive tube to be wound with heater wire outward, and heater wire has thermal insulation layer outward, and thermal insulation layer has airtight protecting cover outward, and protecting cover has the structure of airtight jointer outward.Utilize heater wire to the heating of the well liquid in the heat conductive tube, utilize thermal insulation layer, utilize protecting cover to heater wire sealing and protection, thereby realize that safe and reliable energy-conservation collection is defeated, convenient function of installing heater wire and the insulation of well liquid.This buried pipe heating equipment has safe and reliable, easy for installation and energy-conservation characteristics thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-heat conductive tube among the figure, 2-heater wire, 3-thermal insulation layer, 4-protecting cover, 5-jointer.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this buried pipe heating equipment comprises heat conductive tube 1.The heat conductive tube 1 outer graphite fiber heater wire 2 that is wound with has glass wool thermal insulation layer 3 outside the heater wire 2, airtight protecting cover 4 is arranged outside the thermal insulation layer 3, outside the protecting cover 4 airtight jointer 5 is arranged, and heater wire 2 is connected with power supply through jointer 5.
During actual the use:
This buried pipe heating equipment welding is connected on the pipeline, or is connected on the pipeline, again power supply is connected with jointer 5, can normally use through flange.Electricity is added on the heater wire 2 of this buried pipe heating equipment, and heater wire 2 produces heat, and through 1 pair of well liquid heating of heat conductive tube, and then it is defeated to reach safe and reliable energy-conservation collection, convenient purpose of installing.
Claims (1)
1. a buried pipe heating equipment comprises heat conductive tube (1), it is characterized in that: the outer heater wire (2) that is wound with of heat conductive tube (1), thermal insulation layer (3) is arranged outside the heater wire (2), and airtight protecting cover (4) is arranged outside the thermal insulation layer (3), airtight jointer (5) is arranged outside the protecting cover (4).
