Insulated and high-temperature-resistant silica gel is painted after rust removal, sand blasting, pipe wall roughening, and the silica gel is filled with mica powder and quartz powder, and the insulation and heat conduction properties are raised. A high-temperature electric heat wire with a calculated power and length is connected with a temperature control switch to manufacture a temperature control heating unit, and the temperature control heating unit is twined and pasted on the insulating heat conduction layer. A plurality of groups of temperature control heating unit leading wires are in parallel connection and form an integrated electric heating layer. A layer of insulated high temperature gel is painted on the outer surface of the electric heating layer. The gel is filled with superfine heat preservation insulation perlite, and the insulation, heat preservation, waterproof and shock resistant capabilities are raised. After glass fiber cotton is winded outside the insulation protection layer, a cylinder housing made of stainless steel plate/ an aluminum plate/ an galvanized iron plate is installed.
Description
Technical field
The present invention relates to pipeline tracing technology, particularly relate to pipeline electric tracing technology.
Background technology
Cemented filling produce on, pipeline tracing present situation mainly with water, steam, conduction oil for medium, with the mode of pipeline chuck fluid circulating heat exchange complete fluids within pipes insulation, constant temperature conveying.And these heat mediums of water, steam, conduction oil, boiler, heat exchanger must be furnished with, have these equipment just to have the problem of environmental protection, efficiency, maintenance.Such as: 1, run, drip, leak phenomenon; 2, complexity, huge heating, heat exchange, recycle unit is needed; 3, Long-Time Service, circulation companion hot chamber internal deposition produces the hot blind area of companion.4, corrosion perforation leakage pollution is heated fluid material, especially food, medicine.5, maintenance cost is high, and as aging in conduction oil, volatilization, needs regularly to add replacing; Boiler, heat transmission equipment periodic cleaning, expenses of environmental protection; Steam, water tracing system to stop production freezing prevention tubing winter; The aging ordinary maintenance of recycle unit pump, valve pipe fitting sealing wear is changed; 6, poor thermal efficiency, owing to there being huge thermal cycle heat-exchange system, equipment (as boiler, heat exchanger) the operational efficiency loss of this part, circulation power loss, heat exchange loss, circulation line, pump, valve are incubated unfavorable thermal loss and all there is no need.So environmental issue, safe and sanitary problem, management operating cost, energy consumption efficiency problem, be all current heat tracing pipe road produce present situation.
Electric tracing technology is wide by feat of temperature range, it is little to take up an area, control flexibly, maintenance cost is low, process environments that is that adapt to is wide advantage, pipeline electric tracing is able to Rapid Popularization and uses.Relevant electric heating products as: as invariable power ribbon heater, self-temperature-regulating ribbon heater, heatronic driver, high-temperature metal electrothermal tube, line (MI line).The electric heating products of these difference in functionalitys, by feat of the feature that self is different, also penetrates into pipeline tracing technical field.Such as prevent fluid sets in the conveying of petrochemical industry oil product; Food service industry such as oil, sugar conveying prevent from solidifying; Pharmaceuticals industry fluid constant temperature is carried; Inorganic chemical industry industry inorganic salts prevent crystallization and freezing; Coating industry prevents resin transfer from solidifying etc.The continuous popularization infiltration of electric heating products, electric tracing pipe technology also expose a lot of problem as: 1), construct lack of standardization, distance, large-area construction cannot be grown.2), temperature controls that point for measuring temperature is bad gets, and temperature control is uneven.3), fire prevention, Explosion-Proof.4) insulation, protection, safety problem.
Electrothermal pipe technology disclosed in this patent, in pipeline tracing technical field, dewater, steam, outside conduction oil, opens again new companion's hot mode--electric tracing, and solve electric tracing standardized construction technique, solve temperature control evenly accurate problem, improve insulation, protection, anti-explosion safety characteristic, Related product technical standard of having shaped scheme.For pipeline tracing technical field hew out more energy-saving and environmental protection, technology adapts to product widely, also refinement this art classification simultaneously, filled up original product and to be beyond one's reach technological gap.
Summary of the invention
The object of the invention is: provide one to substitute or to exceed, with water, conduction oil, steam for accompanying pipeline--the electrical heated pipings of thermal medium.
For achieving the above object, on the one hand, technical scheme of the present invention provides a kind of electrothermal pipe heater, comprising: thermal insulation layer, electrothermal layer, insulating protective layer, insulation shell layer.Described thermal insulation layer comprises: eliminate rust at pipe surface, sandblasting is clean, coarsen treatment, increase the adhesive force of pipeline, heat conduction, antiseptic property, there is at the pipe surface brushing one deck processed the silica gel of insulation high-temperature-resistant characteristic, fill with mica powder, silica flour in silica gel, increase the characteristic of dielectric strength, heat conduction, bonding.
Wherein said electrothermal layer: with calculating power, the high-temperature electric hot line of length to be connected with temperature detect switch (TDS) and to be made into temperature control heating unit; And by the temperature control heating unit of making row around being bonded on described thermal insulation layer, the electrothermal layer that after temperature control heating unit lead-in wire is in parallel, composition is overall, it is less that each temperature control heating unit heating surface (area) (HS designs, after one group of heating unit damages, two groups of adjacent heating units, by temperature control start/stop time power increase, and by pipeline body heat transfer among a small circle, the heating function damaging pipeline local area corresponding to electric heating unit can be completed, play compensatory capacity, extend electrothermal pipe useful life.
Wherein said insulating protective layer: be at above-mentioned electrothermal layer outer surface brushing one deck dielectric high temperature glue, fills with ultra-fine insulation insulating material perlite in glue, improves insulation, insulation, waterproof, impact resistance.
Wherein said insulation shell layer: be wound around insulation material outward at described insulating protective layer, as glass fibre cotton, cloth, further thickened heat insulation layer, improves insulating power; Roll the cylinder shell of installation at heat insulation material surface corrosion resistant plate or aluminium sheet or galvanized iron sheet, play dust-proof, waterproof, protecting against shock effect.
Technique scheme is only an optimal technical scheme of the present invention, and tool has the following advantages:
(1), heating is fast, stable;
(2) be, the thermostatic control that product reaches product in the process of conveying, without the need to preparing firing equipment specially again;
(3), ensure that the medium of pipe interior is in temperature constant state;
(4) puzzlement of corroding, effectively can be avoided by the choose reasonable of material;
(5), in electrothermal layer temperature control heating unit is parallel with one another, does not affect integrated piping heating effect after partial destruction;
