The utility model content
Technical problem to be solved in the utility model is, provides a kind of simple in structure, easy to operate oil field to be incubated sheet with carbon material electrical heating membrane, compare with original heat-insulation system energy-conservation more than 50%, to overcome deficiency of the prior art.
The technical solution of the utility model: comprise electrode, insulating barrier and be positioned at the middle electric heating layer of insulating barrier, the electricity heating layer is made up of the carbon material electrical heating membrane that is connected in parallel, and carbon material electrical heating membrane is a disclosed technical scheme in patent CN200510200543.9.
Described carbon material electrical heating membrane is that strip, width are not more than 10cm and are not less than 0.5cm, is arranged in parallel within on the insulating barrier, and the width of carbon material electrical heating membrane bar is wide more, and resistance is more little, heating temp is high more, otherwise then resistance is big more, heating temp is low more.
The resistance of described carbon material electrical heating membrane is between 16 Ω～500 Ω.Because the voltage that we use at present is 220V, environment minimum temperature is-45 ℃, require insulation sheet heating temp scope is 70 ℃～90 ℃, so generally select the carbon material electrical heating membrane of resistance between 16 Ω～500 Ω.
Described insulating barrier is the micarex that two outer surface heat fusions have 150 ℃ of hot melt films of one deck heatproof, and the micarex thickness of insulating barrier insulation face is 0.3～0.6mm, and the micarex thickness at the insulating barrier back side is 2～2.5mm.Select micarex to be because it has good insulation performance performance, good adhesive property and hot pressing performance, have explosion-proof performance, and cost is low as insulating barrier.At the hot melt film of 150 ℃ of the outer surface heat of micarex fusion one deck heatproofs, can guarantee the water resistance of insulating barrier.
Described electrode is two copper-foil conducting electricities.
Described electrode and electric heating layer are connected together by high-temperature electric conduction is gluing, because the utility model heating temp is higher, require the electrode bonding strength higher.When selecting high-temperature electric conduction glue, selection and silicon rubber and the bonding glue of carbon, as high-temperature electric conduction silica gel etc.
Described electrode is by being welded to connect copper conductor, and the position that copper conductor exposes insulating barrier connects with Explosion proof joint, and this design is to consider that the oil field must requirement of explosion.
It is-20 ℃～50 ℃ non-contact type thermostat that described copper conductor is connected with the temperature control scope.
Compared with prior art, the utlity model has following advantage: 1, high energy-efficient performance, the utility model have only 7～8 kilowatts, compare with the heat-insulation system of present employing, and be energy-conservation more than 50%; 2, ease for operation, ease for operation of the present utility model comprises the implication of two aspects, and the one, product itself easy to operate, product is installed simple, easy to operate; The 2nd, owing to the insulation of the utility model to pipeline, valve is mounted on the wall of oil field equipment incubator, not on pipeline, valve, can operate equipment in the time of need not removing, very convenient; To the insulation of oil tank, the utility model is mounted in the outer wall of oil tank, and to the cleaning not influence fully of oil tank, the utility model is compared with existing heat-insulation system, and the oil field existing equipment is had ease for operation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the electric heating layer in the utility model is to select disclosed carbon material electrical heating membrane among the patent CN200510200543.9 for use, because the voltage that we use at present is 220V, environment minimum temperature is-45 ℃, require insulation sheet heating temp scope is 70 ℃～90 ℃, so generally select the carbon material electrical heating membrane of resistance between 16 Ω～500 Ω.When making the oil field with carbon material electrical heating membrane insulation sheet, at first determine its size and shape, full-size generally is no more than 1m * 1.5m, for larger-size heating object, can adopt the polylith oil field to use (using Explosion proof joint to connect) with the parallel connection of carbon material electrical heating membrane insulation sheet.To adopt thickness be the micarex of the 0.3～0.6mm insulation face of producing insulating barrier 1, adopt thickness is the back side that the micarex of 2～2.5mm is produced insulating barrier 1, in order to guarantee insulating barrier 1 water resistance, fuse the hot melt film of 150 ℃ of one deck heatproofs at the outer surface heat of micarex.Then carbon material electrical heating membrane is cut into than the strip of oil field with the short 20～30mm of carbon material electrical heating membrane insulation sheet, its width determines according to the resistance of required heating temperature and carbon material electrical heating membrane, and the carbon material electrical heating membrane bar 2 that shears is arranged in parallel therein on the killinite plate.(should be with the conducting resinl on the electrode 3 (making electrode 3) at selection and silicon rubber and the bonding high-temperature electric conduction glue of carbon with two copper-foil conducting electricities, as high-temperature electric conduction silica gel etc.) electrode 3, carbon material electrical heating membrane bar 2 are fixed together, one end of two copper conductors 4 is peelled off the insulating barrier of about 1cm, with the copper wire of the inside scatter be tiled on the electrode 3 and welding fixing, cover another killinite plate then, two killinite plates are fixed together with the method for bonding or hot pressing.Because the utility model is mainly used in the oil field, so the position that copper conductor 4 exposes insulating barrier 1 connects with Explosion proof joint; In addition, for the ease of operation, control holding temperature, prevent to produce spark, adopting copper conductor 4 to be connected with the temperature control scope is-20 ℃～50 ℃ non-contact type thermostat.
Wherein, the width of carbon material electrical heating membrane bar 2 is to determine like this: because the oil field is 70 ℃～90 ℃ with the heating temp scope that carbon material electrical heating membrane is incubated the sheet surface, after the length of carbon material electrical heating membrane bar 2 is determined, the width of carbon material electrical heating membrane bar 2 is wide more, then resistance is more little, heating temp is high more, otherwise then resistance is big more, heating temp is low more.The width of carbon material electrical heating membrane bar 2 generally is not more than 10cm, is not less than 0.5cm; After if the width of carbon material electrical heating membrane bar 2 reaches 10cm, still temperature is low excessively, can not reach the temperature that needs, just should exchange the littler carbon material electrical heating membrane bar 2 of resistance for, still temperature is too high if the width of carbon material electrical heating membrane bar 2 reaches 0.5cm, can not reach the temperature that needs, just should exchange the bigger carbon material electrical heating membrane bar 2 of resistance for.Before beginning to make, need to determine the width of carbon material electrical heating membrane bar 2 by test.
The utility model generally is installed in the inboard of oil pipe, oil tank heat-insulation layer or the inwall of insulation of equipment case in use.
