Detailed Description
The invention will be further explained with reference to the drawings attached to the specification.
As shown in fig. 1, the utility model provides a multi-tube-bundle high-efficiency heating device, which comprises an oil inlet 1, a heating tube 2 and an oil outlet 6, wherein the oil inlet 1 and the oil outlet 6 are respectively arranged at two ends of the heating tube 2, a plurality of heating tube bundles 11 are arranged in the cavity of the heating tube 2, and two ends of the heating tube bundles 11 are provided with sealing fixing plates 5; a liquid filling opening 3 and an exhaust opening 4 are arranged above the heating pipe 2; the lower part of the heating pipe 2 is respectively connected with two ends of a circulating pipeline 7 through a first connector and a second connector, and an electric heating rod 8 is arranged on the circulating pipeline 7.
A temperature control switch 9 is arranged in a power supply control loop of the electric heating rod 8, and a temperature measuring probe 10 of the temperature control switch 9 is arranged on the outer pipe wall of the heating pipe 2.
As shown in FIG. 2, the heating tube bundle 11 comprises 5-15 heat conducting tubes, which are axially arranged in parallel in the cavity of the heating tube 2.
In the embodiment, an electric heating rod 8 is arranged at one end of a circulating pipeline 7, a temperature control switch 9 is arranged above the electric heating rod 8, a control contact of the temperature control switch 9 is arranged in a power supply control loop of the electric heating rod 8, and a temperature probe 10 transmits temperature data of the outer pipe wall of a heating pipe 2 to an input end of the temperature control switch 9; the heating tube bundle 11 is arranged by 12 steel tubes in parallel, and two ends of the heating tube bundle are fixed by the sealing fixing plates 5 to form a bundle.
The utility model discloses a working process and principle as follows:
the oil inlet 1 and the oil outlet 6 at the two ends of the utility model are arranged in the oil pipeline of the oil extraction site;
before starting the power supply, the heating pipe 2 is filled with preheating liquid from the liquid feeding port 3;
the electric heating rod 8 is electrified to heat the preheating liquid to the temperature preset by the temperature control switch 11, and the heated preheating liquid flows into the heating pipe 2 by the hot water rising principle to heat the liquid oil flowing into the heating pipe bundle 11; the vapor gas generated during heating is discharged from the heating pipe 2 through the exhaust port 4.
Because the heating tube bundle 11 adopts a plurality of steel tubes, the heat exchange area is increased, and the heat exchange efficiency is improved. Meanwhile, an indirect heating mode that the heating rod heats the preheating liquid is adopted, and the heating tube bundle 11 is heated through the preheating liquid, so that the separation of electricity and a heating object is realized, and the equipment is safer. The preheating temperature of the preheating liquid can be adjusted through the temperature control switch 9, so that the rising temperature of the liquid flowing into the heater is ensured to be stabilized within a controllable range in different seasons.
