Abstract
The utility model relates to a crude oil gathering transport device of the petroleum industry, particularly an automatic temperature controlled electric heater, composed of a heating part and an electric controlling part. An electrothermal element with metal cooling ribs and a temperature sensor are arranged in a heating cylinder, and the outer surface of the heating cylinder body is provided with the metal cooling ribs. The utility model adopts a reciprocal interlock mechanism of two temperature controllers to respectively control the temperature of crude oil and the heating cylinder body. The utility model has the advantages of explosion protection, rapid heat transfer, uniform temperature of a heating body, etc., and prevents the surface of the cylinder body from coking and can reduce environment pollution.
Description
The utility model relates to a kind of crude oil transmission device of petroleum industry, especially a kind of temperature automatically controlled electric heater.Be applicable to various producing wells well site oil transportation jar, oil tank, various heavy oil, residual oil can be used for heating.
At present, defeated the outer defeated of well head crude oil that reach of the collection of crude oil need be used heating apparatus, particularly in the winter time, because temperature is low, crude oil fluidity is poor, gives the outer defeated difficulty that causes of crude oil, and the oil transportation in winter of high viscosity, high-solidification point, high waxy oil well is the problem of research tackling key problem always especially, be to solve the outer defeated problem of crude oil, now each oil field generally adopt electrically heated rod, jar with electric heater replace former oil oven, the steam heating mode is heated to crude oil.Though can achieve the goal, there is following problem:
Electrical bar is heated to crude oil, only controls the temperature of crude oil, the easily coking of electrically heated rod surface, fearness dry combustion method, life-span weak point.When crude oil is lower than rod surface temperature in the jar, cut off the electricity supply as untimely, the oil tank explosion accident easily takes place, very dangerous.
Jar is used the electric heater heating mode, and volume is big, and seal is fragile, only controls the temperature of cartridge heater, poor stability, and the construction maintenance capacity is big.
The purpose of this utility model is to provide a kind of explosion-proof, drum surface noncoking, it is fast to conduct heat, the calandria temperature is even, can reduce the temperature automatically controlled electric heater of environmental pollution.
The technical solution of the utility model is: temperature automatically controlled electric heater, be grouped into by heating part and electric control part, and the heating 8 and the temperature sensor ST of band metal fin is housed in heating cylindrical shell 7
29, the outer surface of heating cylindrical shell 7 is equipped with metal fin 10, adopts two mechanisms that temperature controller reciprocal interlocks, and respectively crude oil and heating cylindrical shell 7 is carried out temperature control.
These two temperature controllers chain mechanism mutually are temperature sensor ST
1With temperature controller BT
1Connect temperature sensor ST with lead
2With temperature controller BT
2Connect temperature controller BT with lead

2Reciprocal interlock temperature controller BT
2Control contactor C, the supply terminals of contactor C lower end is connected with lead with the terminals of heating 8, and power supply that will be identical with heating 8 operating voltages is connected with automatic switch ZK upper end with lead.
Be provided with the mounting flange 3 and the pipe nipple mounting flange 5 of heating 8 at an end of heating cylindrical shell 7.Mounting flange 3 is temperature sensor 9 centre-locks, and terminal box 1 is fixing.Fill fire-resistant thermal insulation material (12) between flange 3 and the flange 5.The end of heating cylindrical shell 7 is welded with closure plate 11.
Adopt after the said structure, owing on the heating in outer surface that heats cylindrical shell and heating cylindrical shell metal fin is housed, accelerated the transmission of heat, improved rate of heat exchange, do not need with heat transfer medium also can reach the drum surface noncoking, the fast purpose of conducting heat.Owing to adopted two mechanisms that temperature controller reciprocal interlocks, crude oil is carried out temperature simultaneously with the heating cylindrical shell to be controlled automatically, avoided in the single temperature control method, temperature controller, sensor connecting line are out of order, the oil tank explosion accident that the long-time high temperature heating of heater may cause.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a circuit diagram of the present utility model.
Shown in the accompanying drawing 1 the heating cylindrical shell 7 an end, be fixed with the mounting flange 3 and the pipe nipple mounting flange 5 of heating 8, the heating 8 and the temperature sensor 9 of band metal fin are housed in heating cylindrical shell 7, temperature sensor 9 is fixed on the center of flange 3, terminal box 1 is fixed on the flange 3, heating cylindrical shell 7 surfaces are welded with metal fin 10, and the end of heating cylindrical shell 7 is welded with closure plate 11, fill full fire-resistant thermal insulation material 12 between flange 3 and the flange 5.
