Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, specifically an automatic heating device for fluid pipeline transportation. Background Technology

[0002] In industrial production, fluids require a certain temperature to maintain normal transport when transported through pipelines. For example, during the transport of natural gas, hydrates may form and clog the pipeline at low temperatures. In the oil extraction process, crude oil is transported from the high-temperature area at the bottom of the well to the wellhead, from the wellhead to the metering station, from the metering station to the combined station, and even to the refining terminal. Each of these processes requires maintaining a certain temperature; otherwise, the viscosity of the crude oil will increase, causing solidification and clogging of the pipeline. When the temperature of residential heating water gradually decreases during pipeline transport and cannot meet the heating demand, further temperature needs to be provided.

[0003] In the above applications, conventional heating devices such as heating furnaces can meet the requirements, but the devices are large, the temperature control is inflexible, maintenance is difficult, and they require a large amount of human and physical resources. Utility Model Content

[0004] The purpose of this invention is to provide an automatic heating device for fluid pipeline transportation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic heating device for fluid pipeline transportation, including an inlet pipeline, the bottom end of which is connected to multiple heating sections, and the bottom ends of the multiple heating sections are connected to the same liquid outlet. A front valve is installed at the top end of each heating section, and a rear valve is installed at the bottom end of each heating section.

[0006] Preferably, the top of the heating section is provided with a cleaning port one, and the bottom of the heating section is provided with a cleaning port two.

[0007] Preferably, an inlet valve is installed at the inlet pipeline and an outlet valve is installed at the outlet.

[0008] Preferably, an inlet temperature sensor is installed at the inlet pipeline and an outlet temperature sensor is installed at the outlet.

[0009] Preferably, the heating section has an inductor coil wrapped around its outer surface, a heating rod inserted inside the heating section, and heating plates cut into the wall of the heating section.

[0010] Preferably, the heating section is connected to the inlet pipeline and the outlet via a flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] After the fluid enters the inlet pipe through the inlet valve, it can flow evenly to each heating section because the structures are exactly the same.

[0013] This heating device uses high-precision inlet and outlet temperature sensors to measure the fluid temperature within the pipeline. It employs the PID function of a high-precision temperature controller to control the output voltage of the power regulator, achieving high-precision temperature regulation. The fluid outlet temperature can be set via the touchscreen on the distribution box. Once set, the device automatically adjusts the power output to ensure the outlet temperature reaches the set value. The heating components are all connected by flanges, forming a single unit when assembled, and also facilitating transportation and maintenance after disassembly.

[0014] Each heating section in the heating device is equipped with valves at both ends. The section has a cleaning port, which can be used as an exhaust port and a sampling port. When the heating temperature decreases under the same conditions, the heating section can be cleaned. During cleaning, close the valves at both ends, drain the internal fluid from the cleaning port, connect the cleaning pipeline, inject the cleaning fluid, drain the cleaning fluid after cleaning, close the cleaning port valve, and open the valves at both ends to allow the fluid to enter.

[0015] This heating device can be used in series or in parallel depending on the actual situation.

[0016] This utility model is small and flexible, with very low maintenance costs. It requires almost no personnel on duty and can achieve automatic temperature control, remote control, etc., making it very convenient to operate. Attached Figure Description
