Description

Technical Field

[0001] This invention belongs to the field of asphalt transportation technology, specifically relating to a heating device and heating method for a China Railway skin tank container. Background Technology

[0002] In the packaging and transportation of asphalt containers, based on the characteristics of the medium during loading, unloading, and transportation, asphalt initially exists as a liquid at 120-150℃ at the loading point, then naturally cools during transport to become a solid "sugar core." Upon arrival at the unloading point, it is melted back to a liquid state above 120℃ using heating equipment before being unloaded into tanks or transported by truck to the destination for unloading. Due to factors such as loading and unloading efficiency and cost control, various types of asphalt containers and heating methods have emerged. According to container type, they can be divided into insulated tank containers and dry bulk containers. According to different heating methods, they can be divided into internally heated containers and externally heated containers.

[0003] Traditional heating methods for tank-type containers all involve installing a burner with heating pipes inside the container. The burner burns diesel or natural gas to generate heat, which is then used to heat the asphalt through the heating pipes inside the tank-type container. The disadvantages are low heating efficiency, high heating cost, and environmental pollution caused by the burner during combustion. Summary of the Invention

[0004] The purpose of this invention is to provide a heating device and method for China Railway's skin-type tank containers, so as to solve the problems of low heating efficiency, high heating cost, and environmental pollution caused by the burner during combustion in the current skin-type tank container heating method.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A heating device for a China Railway skin tank container includes a China Railway skin asphalt tank, an inner heat exchanger is installed inside the China Railway skin asphalt tank, the asphalt outlet of the inner heat exchanger is connected to the inlet of a first asphalt pump through a first pipeline, the outlet of the first asphalt pump is connected to the inlet of an outer heat exchanger through a second pipeline, and the outlet of the outer heat exchanger is connected to the top of the China Railway skin asphalt tank through a third pipeline.

[0007] The asphalt outlet at the bottom of the CRRC skin asphalt tank is connected to the first pipeline near the inlet of the first asphalt pump via the fourth pipeline.

[0008] The fifth pipeline connects to the third pipeline and the inlet of the spare box, respectively;

[0009] The outlet of the spare tank is connected to the inlet of the second asphalt pump via the sixth pipeline, and the outlet of the second asphalt pump is connected to the first pipeline via the seventh pipeline.

[0010] Furthermore, a first valve is installed on the first pipeline between the seventh pipeline and the fourth pipeline; a second valve is installed on the fourth pipeline near the first pipeline; a third valve is installed on the fourth pipeline near the asphalt outlet below the asphalt tank of China Railway Skin; a fourth valve is installed on the seventh pipeline; a fifth valve is installed on the third pipeline; the fifth pipeline is located between the external heat exchanger and the fifth valve; and a sixth valve is installed on the fifth pipeline.

[0011] Furthermore, the asphalt outlet of the internal heat exchanger is connected to the oil inlet of the asphalt tank of China Railway Skin, and the asphalt inlet of the internal heat exchanger is connected to the inner cavity of the asphalt tank of China Railway Skin.

[0012] Furthermore, the third pipeline and the observation port above the China Railway skin asphalt tank are inserted into the China Railway skin asphalt tank.

[0013] A heating method for a China Railway skinned tank container, utilizing any of the above-mentioned China Railway skinned tank container heating devices, includes the following steps:

[0014] S1. Check whether the temperature of the asphalt base in the asphalt box of China Railway skin is lower than the first set temperature. If not, this heating method will not run. If so, proceed to step S2.

[0015] S2. Control the opening of the first and fifth valves, and the closing of the second, third, fourth and sixth valves. Start the first asphalt pump. The asphalt in the asphalt tank of China Railway skin passes through the internal heat exchanger, the first valve, the first asphalt pump, the external heat exchanger and the fifth valve in sequence and returns to the asphalt tank of China Railway skin, so as to realize the circulation heating of the asphalt.

[0016] S3. When the asphalt temperature in the asphalt tank of the steel skin rises above the second set temperature, the second valve, the third valve and the sixth valve are opened, while the first valve and the fifth valve are closed. The high-temperature asphalt enters the standby tank in sequence through the third valve, the second valve, the first asphalt pump, the external heat exchanger and the sixth valve.

[0017] S4. When the asphalt temperature in the asphalt tank of China Railway skin is lower than the second set temperature, the first asphalt pump is turned off, and the second and third valves are closed at the same time. The fourth valve and the second asphalt pump are opened. The asphalt in the spare tank passes through the second asphalt pump, the fourth valve and the internal heat exchanger in sequence. After being heated by the internal heat exchanger, the low-temperature asphalt in the asphalt tank of China Railway skin is heated.

[0018] Compared with existing technologies, the heating device and heating method for CRRC skin tank containers in this application can shorten the heating time by more than 15 hours and reduce energy consumption by 50% compared with traditional heating methods. It is a new type of heating method that is efficient, energy-saving and environmentally friendly. Attached Figure Description

The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention.

[0023] like Figure 1 As shown, this application provides a heating device for a China Railway skin tank container, including a China Railway skin asphalt tank 1, an internal heat exchanger 2 disposed inside the China Railway skin asphalt tank 1, and the asphalt outlet of the internal heat exchanger 2 extending through the asphalt inlet of the China Railway skin asphalt tank. The asphalt inlet of the internal heat exchanger is located inside the China Railway skin asphalt tank. The asphalt outlet of the internal heat exchanger 2 is connected to the inlet of a first asphalt pump 4 through a first pipeline 3. A first valve 5 is provided on the first pipeline 3. The outlet of the first asphalt pump is connected to the inlet of an external heat exchanger 7 through a second pipeline 6. The outlet of the external heat exchanger is connected to the top of the China Railway skin asphalt tank 1 through a third pipeline 8. Specifically, the third pipeline 8 passes through the observation window 9 above the China Railway skin asphalt tank and extends into the China Railway skin asphalt tank 1. A fifth valve 10 is provided on the third pipeline 8.

[0024] The asphalt outlet below the asphalt tank 1 of China Railway skin is connected to the first pipeline 3 between the first valve 5 and the first asphalt pump 4 via the fourth pipeline 11, and a second valve 12 is installed on the side of the fourth pipeline 11 near the first pipeline, and a third valve 13 is installed near the asphalt outlet.

[0025] A fifth pipe 14 is connected to the third pipe 8 between the external heat exchanger 7 and the fifth valve 10. The other end of the fifth pipe 14 is connected to the inlet of the spare tank 17. A sixth valve 16 is installed on the fifth pipe 14.

[0026] The outlet of the spare tank is connected to the inlet of the second asphalt pump 19 via the sixth pipeline 18, and the outlet of the second asphalt pump is connected to the first pipeline 3 via the seventh pipeline 21. A fourth valve 20 is installed on the seventh pipeline 21.

[0027] A first temperature sensor is installed inside the asphalt tank of China Railway Skin, and a second temperature sensor is installed near the outlet of the asphalt tank of China Railway Skin. Both the first and second temperature sensors are connected to the controller via electrical signals. At the same time, the controller is connected to each valve, the first asphalt pump and the second asphalt pump via electrical signals.

[0028] This application also relates to a heating method for a China Railway skinned tank container, comprising the following steps:

[0029] S1. Check whether the temperature of the asphalt base in the asphalt tank of China Railway skin is lower than the first set temperature. This technical solution is applicable to the working condition where the temperature of the asphalt base in the asphalt tank of skin is lower than 60℃. Therefore, the first set temperature is 60℃. If not, this heating method will not run. If so, proceed to step S2.

[0030] S2. Control the opening of the first and fifth valves, and the closing of the second, third, fourth, and sixth valves. Start the first asphalt pump. The asphalt in the China Railway skin asphalt tank returns to the China Railway skin asphalt tank in sequence through the internal heat exchanger, the first valve, the first asphalt pump, the external heat exchanger, and the fifth valve, thereby achieving circulating heating of the asphalt. The temperature of the asphalt at the outlet of the China Railway skin asphalt tank is increased so that the asphalt can flow out from the third valve.

[0031] S3. When the asphalt temperature in the asphalt tank of the steel skin rises above the second set temperature, in this embodiment, the second set temperature is 110°C. The second valve, the third valve and the sixth valve are opened, while the first valve and the fifth valve are closed. The high-temperature asphalt enters the standby tank in sequence through the third valve, the second valve, the first asphalt pump, the external heat exchanger and the sixth valve.

[0032] S4. When the asphalt temperature in the asphalt tank of China Railway skin is lower than the second set temperature, the first asphalt pump is turned off, and the second and third valves are closed at the same time. The fourth valve and the second asphalt pump are opened. The asphalt in the spare tank passes through the second asphalt pump, the fourth valve and the internal heat exchanger in sequence. After being heated by the internal heat exchanger, the low-temperature asphalt in the asphalt tank of China Railway skin is heated.

[0033] This invention relates to a novel heating method for insulated tank containers, comprising an inlet heater, an asphalt pump, an external heat exchanger, an outlet heater, and a spare asphalt tank. The insulated tank container enters the heating station, where the outlet heater is connected to the container's oil inlet, and the inlet heater is connected to the container's observation port. Cold oil inside the insulated tank container enters the external heat exchanger through the outlet heater to exchange heat with heat transfer oil. After heat exchange, hot oil enters the insulated tank container through the asphalt pump and the inlet heater to mix with the cold oil, thus heating the oil. This novel heating method for insulated tank containers can shorten heating time by more than 15 hours compared to traditional methods and reduce energy consumption by 50%, making it a highly efficient, energy-saving, and environmentally friendly heating method.

For those skilled in the art, several modifications and improvements can be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
