Description

Technical Field

[0001] This utility model relates to the field of oilfield equipment technology, specifically to a resistance-type crude oil heating water jacket furnace. Background Technology

[0002] A water-jacketed heating furnace is a type of furnace that indirectly heats crude oil using water as a heat carrier. It consists of a water jacket, boiling tubes, circulating oil pipes, burners, and safety accessories. It is mainly used in oil well sites and oil pipelines to heat crude oil, reducing its viscosity and increasing its fluidity.

[0003] In existing technologies, heating is generally achieved through fuel combustion, which generates a large amount of flue gas during the heating process. When the flue gas is discharged, it causes air pollution. Therefore, a cleaner water-jacketed heating furnace is needed. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a resistance-type crude oil heating water jacket furnace, which solves the problem mentioned in the background technology that heating by fuel combustion generates a large amount of flue gas during the heating process, causing air pollution when the flue gas is discharged.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a resistance-type crude oil heating water jacket furnace, comprising a furnace body and a pipeline. One end of the furnace body has an inlet and an outlet. One end of the pipeline passes through the inlet into the furnace body, bends inside the furnace body, and extends out from the outlet. The pipeline is welded to the inlet and the outlet. A pressure relief valve is installed at the top of the furnace body, and the sensing end of the pressure relief valve is connected to the interior of the furnace body. One end of the furnace body has an arc-shaped through groove. A sealing plate that matches the arc-shaped through groove is bolted to the outer wall of the furnace body. An electric heater connected to the interior of the furnace body is installed on the sealing plate. The electric heater is close to the inner lower side wall of the furnace body. The end of the sealing plate away from the electric heater has a socket electrically connected to the electric heater.

[0006] By adopting the above technical solution, an appropriate amount of water is added to the furnace body, and an external power cord is plugged into a socket to supply power to the electric heater. This causes the electric heater to generate heat through resistance, which in turn heats the water. The high-temperature steam then heats the pipes. Both ends of the pipes are connected to oil pipelines. Crude oil flows in from the inlet end of the pipes, then flows through the pipes, and finally flows out from the outlet end of the pipes. This achieves the purpose of heating the crude oil and avoids air pollution caused by the emission of flue gas.

[0007] Optionally, the sealing plate is provided with a sealing gasket at one end near the furnace body, with one end of the sealing gasket tightly attached to the furnace body.

[0008] By adopting the above technical solution, the sealing gasket is used to improve the sealing performance between the sealing plate and the furnace body, prevent water leakage, and reduce water loss.

[0009] Optionally, the outer wall of the furnace body is provided with an upper connecting pipe and a lower connecting pipe, which are located near the top and bottom of the furnace body, respectively, and one end of the upper connecting pipe and the lower connecting pipe is connected to a liquid level pipe.

[0010] By adopting the above technical solution, the upper connecting pipe and the lower connecting pipe are used to facilitate the flow of water in the furnace body into the liquid level pipe, so that the water level in the liquid level pipe is equal to the water level in the furnace body, thereby making it easier for personnel to observe the water level height in the furnace body.

[0011] Optionally, the level gauge has a scale on its outer wall.

[0012] By adopting the above technical solution, the scale is used to facilitate personnel to observe the specific height of the water level in the furnace, making it easier for personnel to accurately adjust the water level.

[0013] Optionally, two opposing support frames are welded to the outer wall of the furnace body, and bases are welded to the bottom of the two support frames. Mounting holes are provided at the four corners of the bases.

[0014] By adopting the above technical solution, the support frame and the base cooperate to support the equipment, and the mounting holes are used to facilitate the installation of the equipment in a designated position, thereby improving the stability of the equipment.

[0015] Optionally, a thermometer is installed on the outer wall of the furnace body, and the sensing probe of the thermometer extends into the interior of the furnace body.

[0016] By adopting the above technical solution, the thermometer is used to monitor the temperature in the furnace in real time, so that the temperature in the furnace is kept within a suitable range. When the temperature in the furnace is too low or too high, it is convenient for personnel to adjust the temperature or to adjust for faults.

[0017] Optionally, the top and bottom of the furnace body are respectively provided with a water inlet pipe and a drain pipe, and both the water inlet pipe and the drain pipe are provided with a sealing cap. The inner side wall of the sealing cap is provided with an internal thread, and the outer wall of the water inlet pipe and the drain pipe is provided with an external thread. Both the water inlet pipe and the drain pipe are threadedly connected to the sealing cap.

[0018] By adopting the above technical solution, the water inlet pipe and the water outlet pipe are used to supply water to and drain water from the furnace body, which facilitates the adjustment of the water level. The sealing cover is used to seal the water inlet pipe and the water outlet pipe to prevent water from overflowing.

[0019] (III) Beneficial Effects In summary, this utility model has at least one of the following beneficial technical effects: This resistance-type crude oil heating water jacket furnace adds an appropriate amount of water to the furnace body and plugs an external power cord into a socket to supply power to the electric heater. This causes the electric heater to generate resistance and heat the water, which in turn generates high-temperature steam to heat the pipeline. Both ends of the pipeline are connected to oil pipelines. Crude oil flows in from the inlet end of the pipeline, then flows through the pipeline, and finally flows out from the outlet end of the pipeline. This achieves the purpose of heating the crude oil and avoids air pollution caused by the emission of flue gas. Attached Figure Description
