Abstract

The utility model discloses an oil immersion type electromagnetic pipeline heater. An outer case body is sleeved on a core tube external layer; an inner ring container is arranged in the outer case body to divide space enclosed by the outer case body and the core tube into an inner cavity body and an outer cavity body; the outer cavity body is filled with a solid-state heat insulation material; the inner cavity body is provided with a support body and an electromagnetic coil, and is filled with conduction oil; the outside of the outer case body is provided with an electric cabinet, and is radially provided with a point for measuring temperature; the electric cabinet is connected with the electromagnetic coil; and a connecting flange is fixed with the core tube. The oil immersion type electromagnetic pipeline heater is provided with the inner ring container, the conduction oil and the heat insulation material based on heating of the prior electromagnetic coil, so the oil immersion type electromagnetic pipeline heater has more excellent heating effect and heat insulation effect, and can achieve the best effect through the control of the electric cabinet.

Description

Oil immersed type electromagnetic pipeline heater

Technical field

The utility model relates to a kind of heater, is that a kind of the extraction at crude oil at the oil field collects in the production process of failing specifically, need heat designed heater to ducted crude oil or gas mixture.

Background technology

At present, utilizing metallic conduit to transport crude oil is that crude oil is gathered main economical and practical approach in the course of conveying.Adopt the crude oil that comes from deep under ground and be extracted into ground,, make the crude oil can't normal transport because the reduction of temperature can be solidified coking.So, be necessary crude oil is heated.Traditional heating means are twined the efficiencies of heating surface lower (minimum only is 20%) such as heating as water jacket furnace heating, ribbon heater, waste energy, and contaminated environment, incompatibility expanding economy needs.And the disclosed patent No. of Patent Office of the People's Republic of China is a kind of electromagnetism heating tube of 200520129486.5, is a kind of new pipeline heating means, and it is fast that it has firing rate, is convenient to advantages such as maintenance and easy construction.But it has only adopted coil heats, and heating uniformity is bad, and heat-insulating property is not good.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design, with low cost, the electromagnetic pipeline heater being convenient to keep in repair are provided, and can overcome the not good shortcoming of existing heat-insulating property and heating properties.

In order to achieve the above object, the technical solution adopted in the utility model is: outer case, core pipe, solenoid, flange, point for measuring temperature, outer case is sleeved on the core outer tube layer, ring container in being equipped with in the outer case, the space that outer case is become with the core circumference of cannon bone is divided into inside and outside two cavitys, outer chamber is equipped with solid-state insulation material, inner chamber body is equipped with supporter and solenoid, and falling heat-transfer oil, the outside electric cabinet of installing of outer case, radially be provided with point for measuring temperature, electric cabinet links to each other with solenoid, and adpting flange and core pipe are connected.

The utility model has the advantages that:

Because the utility model has increased interior ring container, conduction oil and insulation material on the basis of original solenoid heating, make heating, heat insulation effect excellent more, by electric cabinet control, can reach best effect.

Description of drawings

Fig. 1 is the utility model structural representation;

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, the utility model comprises outer case 1, core pipe 5, solenoid 6, flange 7, point for measuring temperature 8, outer case 1 is sleeved on core pipe 5 skins, ring container 3 in being equipped with in the outer case 1, the space that outer case 1 and core pipe 5 are surrounded is divided into inside and outside two cavitys, outer chamber is equipped with solid-state insulation material 2, inner chamber body is equipped with supporter 4 and solenoid 6, and falling heat-transfer oil 10, the outer case 1 outside electric cabinet 9 of installing, radially be provided with point for measuring temperature 8, electric cabinet 9 links to each other with solenoid 6, and adpting flange 7 and core pipe 5 are connected.

Form the insulation space between interior ring container 3 and the outer case 1, outer case 1 can be prevented rainwater, and its spacing size can be with the different best heat insulation effect and the economic thickness of reaching as calculated of heater power and environment of living in; Form the exchange heat layer between interior ring container 3 and the core pipe 5, the heat of solenoid 6 carries out heat transmission by the convection current of conduction oil 10 (or heat-conducting silicone grease etc. solid-state or liquid have a good content of insulation heat-conducting property) or the method for conduction and the zone that core pipe 5 is not covered by solenoid 6, improves the utilization rate of electric heating and the temperature rise of clamp solenoid 6.Solenoid 6 supported bodies 4 in the exchange heat layer are fixed on the spacing that is fit to and form some main thermals treatment zone on the core pipe 5.Radio-frequency generators in the electric cabinet 9 produce the high frequency alternating currents and produce action of alternating magnetic field in core pipe 5 solenoid 6 in by lead, at the tube wall generation eddy current of core pipe 5 and generate heat.Make crude oil reach 75-80 degree centigrade process value.The thickness of exchange heat layer obtains with the various computing of heating power.

The utility model has given one's full attention to the heating of solenoid 6 itself and the problem of heat utilization.Solenoid 6 heatings, the coil insulation thing can wear out when temperature raises, and if this heat does not utilize and will waste.So, added conduction oil 10 and controlled solenoid 6 temperature rises.The zone that is covered by solenoid 6 not, its temperature is far below the temperature of the electromagnetism thermal treatment zone, and this has just formed the heat exchange based on convection current or conduction.By near the pipeline oil-out point for measuring temperature 8 is set radially, feeds back to electric cabinet 9 and form closed-loop control, utilized the heat of solenoid 6 to control its temperature rise again fully.

In addition,,, require its material to present soft magnetism or middle soft magnetism, so that the heating best results owing to be the electromagnetism heating for core pipe 5.
