Abstract
The utility model provides an explosion-proof type electromagnetic heating rod for a tank. The explosion-proof type electromagnetic heating rod mainly comprises an explosion-proof junction box, a flange, a heating pipe, an intermediate frequency solenoid and a coil support. The explosion-proof type electromagnetic heating rod is connected to the outside of an oil tank through a flange, and heats the oil medium through a heating means of cutting the heating pipe (housing ) outside the magnetic field of the solenoid. The explosion-proof type electromagnetic heating rod is safe, energy-saving and maintenance-free and is high in heat conversion efficiency. When high frequency (10-40kHz) and high-voltage current runs through the solenoid, the solenoid generates a magnetic field changing rapidly, and the magnetic lines cut the heating pipe to generate numerous small eddy current and heat by itself. High temperature resistant and insulation cotton is arranged between the solenoid and the heating pipe to prevent the heat of the housing from dispersing inwardly, so that almost all the high frequency and high-voltage current running through the solenoid is converted into heat energy. The energy loss is less, the electric-heat conversion efficiency reaches 98%, and the energy-saving effect is 30% higher than that of the prior art.
Description
Technical field
The utility model relates to a kind of firing equipment for oil field oil storage tank or large tank, is specifically related to a kind of explosion-proof type tank electromagnetic heating rod.
Background technology
All there is the oil well of the geographical remote location of part, high solidifying viscous crude, poor fluidity in the each oil field of China, is first crude oil to be left in temporarily and recover the oil in on-the-spot oil tank, the method for then being transported by tank car unification again for the common practice in this type of current each oil field of oil well.Owing to leaving in, crude oil in oil tank can increase gradually along with its viscosity of the reduction of temperature, mobility variation, is unfavorable for entrucking and the transport of tank car, and the way addressing this problem is that crude oil is heated again.
The heating means that are widely used at present on oil tank are resistance wire heating heaters, centered by its feature, the temperature of heating wire is no more than 500 degree higher than skin temperature (heat spreads from inside to outside) and shell maximum temperature, because being adopts the directly method of heating of resistance wire, in the time of practical application, there is the problems such as the efficiency of heating surface is low, heating-up temperature (power) is wayward and energy consumption is high, failure rate is high, maintenance replacing is inconvenient.
Summary of the invention
For overcoming the deficiency of background technology, the purpose of this utility model is to provide that a kind of efficiency of heating surface is high, heating-up temperature (power) is controlled, energy consumption, failure rate is low, non-maintaining explosion-proof type tank electromagnetic heating rod.
The utility model electromagnetic heating apparatus mainly adopts electromagnetic induction to make metal produce eddy current and the design of self-heating, thereby overcomes the problem existing in background technology.
For achieving the above object, the technical scheme that the utility model is taked is: described explosion-proof type tank is made up of explosion-proof wiring box, heating tube, intermediate frequency electromagnetic coil, coil brace with electromagnetic heating rod, and electro-heat equipment is shell; , on coil brace, being wound around high-temperature plastic belt, intermediate frequency electromagnetic coil winding is on high-temperature plastic belt, and high-temperature-resistant thermal-insulation layer is wrapped on intermediate frequency electromagnetic coil, is finally welded on explosion-proof wiring box by outer field heating tube shell; It is in 10～40KHz, resonance potential 2000V that described intermediate frequency electromagnetic coil can be operated in frequency, intermediate frequency electromagnetic coil winding is on coil brace, metal heat-generating pipe (shell), in coil outside, is shaken and is made it from body eddy-current heating by magnetic field, and enclosure material is selected CrMn alloy steel products.
Solenoid adopts anti-oxidant, resistant to elevated temperatures nickel plating wire, and heater is fixed on oil tank by ring flange.
Adopt the working method of cutting heating tube (shell) heating outside solenoid magnetic field, its operation principle is: in the time having high frequency (10 ~ 40KHz), high-tension current to flow through in coil, solenoid just can and produce the magnetic field changing at a high speed, magnetic force line cutting heating tube (shell), make the countless little eddy current of generation in its body, and self-heating.High-temperature-resistant thermal-insulation cotton is set again between solenoid and heating tube (shell) and prevents that shell heat from inwardly spreading, therefore flow through the high frequency of coil, the energy that high-tension current is changed is almost all changed for heat, minimum its electric conversion efficiency of energy loss is up to 98%, and energy-saving effect more exceeds more than 30% than conventional art.
Daily non-maintaining, because solenoid self does not generate heat, and be just never adjusting after high temperature resistant, anti-oxidant wire once-forming, therefore its normal service life more than 10 years, thereby do not avoided again the danger of short circuit, electric leakage with heating Metal Contact due to solenoid.
Heating-up temperature (power) is controlled: large tank intermediate frequency electromagnetic heater adopts the power supply of inversion intermediate frequency power supply, can regulate intermediate frequency power supply power output according to the real-time automatic or manual of the temperature data collecting, thus control heater heating power.
Material requirements: large tank intermediate frequency electromagnetic heater groundwork medium is crude oil, its composition medium sulphide content is dangerous maximum to corrosion of metal, therefore the length in heater life-span depends mainly on the degree of the anti-halophile corrosion of shell, again because the Electromagnetic Heating degree of depth (electric heating conversion) requires therefore enclosure material to select CrMn alloy steel products.Solenoid requires the nickel plating wire of anti-oxidant, high temperature resistant (> 500 spends).
Large tank intermediate frequency electromagnetic heater process: 1, by high-temperature insulation wire by design parameter coiling and be fixed on coil brace; 2, on the good solenoid of coiling, wrap up the thick insulation material of 20 ~ 35mm; 3, by the solenoid processing by pushing in anti-explosion terminal box in heating tube (shell).4, solenoid lead-in wire is connected in anti-explosion terminal box terminal block.
By the integrated use of above technological means, effectively overcome the shortcoming and defect existing in oil field tank heater in the past.
