Abstract
A soft electrical heating plate type heater on oil pipeline consists of a multilayer materials coating the oil pipeline comprising afire interrupter lagging, an electric heating layer, a thermal insulation material layer, a waterproof material layer from inside to outside. The utility model is characterized in that the electric heating layer formed by parallel connection of the soft electrical heating plate, a thin nonmetal conductive material carbon fiber paper, a high-intensity insulating material glass cloth at the two side are formed into a rectangular; the opposite edge is fixedly provided with copper foil electrode wire which is compounded into ultra-thin soft electrical heating plate after being pressed and thermosetting; when the oil pipeline is twisted into cylinder in shape, the circuit between the rectangular plate is formed by parallel connection of the copper foil electrode wire. The utility model has the advantages of being high efficient and energy saving, safe and lone working life, no pollution, and convenient maintenance. The electrothermal conversion efficiency of the soft electrical heating plate reaches over 98 percents, thereby having obvious energy-saving effect; no blazing fire is generated when the soft electrical heating plate is working, thereby having high reliability with total parallel circuit and working for more than 20years. The utility model is suitable for the heater on oil pipelines.
Description
(1) technical field
The utility model belongs to the oil country tubular good heating equipment, particularly a kind of oil transport pipeline heater that adopts ultrathin flexible face electric hot plate as the heating thermal source.
(2) background technique
In the China's oil exploitation, in the majority with low-sulfur paraffin wax base at present, its fusing point when temperature is low slightly, promptly can take place because of coagulating the cured oil retrogradation that makes between 48 ℃-58 ℃, and flow resistance increases, and gives collection the defeated difficulty of bringing.Usually adopt steam or hot water directly oil or tracer line to be heated oil, heat waste is big, and heat is imitated low, and the maintenance load of steam or water-heating boiler pipeline is big, poor stability.In recent years, occur multiplely making the heating means of thermal source, on transport pipe, scribble isolation layer, electric-heating coatings is sprayed on the transport pipe after insulation is handled, become electric heating film after the drying as Chinese patent " ZL95220546.7 electrothermal membrane type Crude oil heater " with electric energy.Be surrounded by isolation layer, reflect radiation heat layer, insulation layer, watertightness barrier on electric heating film successively, electric heating film is provided with electrode, inserts power controling box with lead, gets final product.And for example Chinese patent " ZL98214013.4 electric heating film pipeline local heater " is same, by being coated with electric heating film on the insulation tile inwall, as the electric heating thermal source.This electric heating film heating, the flames of anger, Security is good, thermal efficiency height, but the deficiency that exists is that electrically-conducting paint belongs to two kinds of materials that thermal coefficient of expansion is different with insulating carrier, in its interface contact using process, can cause microcosmic to misplace, chap, come off because of expanding with heat and contract with cold, directly have influence on heating efficiency and working life.
(3) summary of the invention
The purpose of this utility model is: design and produce the board-like oil transport pipeline heater of a kind of flexible face electric heating, employing has the high-strength insulating material glass fiber cloth by the two sides pressing of non-metallic conducting material carbon fiber paper, form ultrathin flexible face electric hot plate, make the oil transport pipeline heater as the electric heating thermal source, reach simple in structure, easy to make, energy-efficient, the purpose of long-life safety.
The technical solution of the utility model is following realization, the board-like oil transport pipeline heater of a kind of flexible face electric heating, constitute by the multilayer material that is wrapped on the oil transport pipeline, be the fire lagging that the flexible mica tape of nonmetal heatproof insulating material constitutes from inside to outside successively, the flexible face electric hot plate electric heating layer that constitutes in parallel, be surrounded by the adiabator layer of aluminium foil thermal reflecting coating surface layer, waterproof layer, in each layer termination the waterproof end cap is housed, be provided with the explosion-proof electrification terminal box that metal card connects outside watertightness barrier, the electrode wire of electric heating layer inserts electric control box by wiring terminal in the explosion-proof electrification terminal box and external power cord; Be provided with temperature transducer at the oil transport pipeline inwall, insert electric control box with feeder line.
The concrete structure of the flexible face electric hot plate electric heating layer that constitutes in parallel is, by thin layer non-metallic conducting material carbon fiber paper with at the high-strength insulating material glass fiber cloth on its two sides, arrange into rectangle, be fixed with the copper foil electrode line on the opposite side, through pressing, heat cure, be combined into ultrathin flexible face electric hot plate, when the parcel oil transport pipeline was wound into tubular, the circuit between the rectangular panel blocks was made of the copper foil electrode line parallel.
Using method of the present utility model is, when oily temperature is lower than the setting temperature scope in the oil transport pipeline, automatic control system instruction energising, electric heating layer produces heat energy, by conducting in the fire-proof insulation course pipeline, the oil body in the pipeline is given in radiation, makes oil body realize heating up under conduction, convection current, three kinds of heat energy circulation ways of radiation and falls resistance.When the oil temperature surpassed the setting temperature scope, the outage of automatic control system instruction part face electric hot plate stopped heat supply, and retaining part face electric hot plate continues the heat supply insulation, fundamentally guarantees up to standard, energy-conservation, safe and anti-coking.
The utility model has the advantages that: energy-efficient, safety is long-lived, does not pollute, and is easy to maintenance.The electric conversion efficiency of flexible face electric hot plate reaches more than 98%, and thickness is ultra-thin, and thermal capacity is little, and thermal inertia is little, and heat dispersing surface is big, and thermal response is fast, and warming velocity is fast, and can reach the maximum temperature of setting power tens seconds; And can launch the XIR Extreme Infrared that crest is the 5-8 micron, with the radiation mode permeability oil be heated, its energy flux density is 70 times of convection current energy flux density, and energy-saving effect is outstanding.The flames of anger during work of flexible face electric hot plate, full parallel circuit, the reliability height, can reach 20 years working life.Be applicable to the electric heater of oil transport pipeline.
