[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0023] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, and connection should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.
[0024] See Figure 1 , the crude oil photoelectric heating system according to the embodiment of the present invention includes a solar heat collection device 1, an electric heating device 4, an energy storage device 5, a heat dissipation device 6, a heat exchange device 9, an oil pipeline 10 and a circulating liquid pipeline 11;
[0025] The solar heat collection device 1, the electric heating device 4, the energy storage device 5 and the heat dissipation device 6 are all connected in communication on the circulating liquid pipeline 11 and are used for heat exchange with the circulating liquid;
[0026] The liquid inlet of the heat exchange device 9 is connected to the liquid outlet of the circulating liquid pipeline 11, the liquid outlet of the heat exchange device 9 is connected to the liquid inlet of the circulating liquid pipeline 11, and the oil pipeline 10 flows through the heat exchange device 9 for heat exchange between the crude oil and the circulating liquid.
[0027] Each device constituting the above crude oil photoelectric heating system can be used alone or in combination according to specific application scenarios, and the present utility model does not limit this.
[0028] Exemplarily, when the heat collected by the solar heat collection device 1 can fully meet the temperature required for the crude oil in the oil pipeline 10, at this time, the electric heating device 4 does not start, and the energy collected by the solar heat collection device 1 is directly used to heat the crude oil in the oil pipeline 10.
[0029] When the heat collected by the solar heat collection device 1 cannot meet the temperature required for the crude oil in the oil pipeline 10, at this time, the electric heating device 4 can be started to supplement heat to the circulating liquid, and the power of the electric heating device 4 can be flexibly adjusted as needed to meet the temperature required for the crude oil in the oil pipeline 10.
[0030] When the heat collected by the solar heat collection device 1 can heat the crude oil in the oil pipeline 10 to the required temperature and there is still surplus heat in the solar heat collection device 1, at this time, the energy storage device 5 can be started to store the excess heat to achieve the purpose of energy saving. When this part of heat is needed, the energy storage device 5 is started again to supplement heat to the circulating liquid to meet the temperature required for the crude oil in the oil pipeline 10.
[0031] When the solar heat collection device 1 does not collect heat, through the switch, the energy storage device 5 is started to release the excess heat and supplement heat to the circulating liquid to meet the temperature of the crude oil in the oil pipeline 10. If the heat released by the energy storage device 5 is not enough to meet the temperature required for the crude oil in the oil pipeline 10, at this time, the electric heating device 4 is started again to supplement heat to the circulating liquid, and the power of the electric heater can be automatically adjusted as needed to meet the temperature required for the crude oil in the oil pipeline 10.
[0032] When the heat collected by the solar heat collection device 1 is excessive, through the switch, the energy storage device 5 is started to store the excess heat and then provide heat to the circulating liquid, and it can still meet the temperature of the crude oil in the oil pipeline 10. At this time, if there is still too much heat that cannot be released, at this time, the heat dissipation device 6 needs to be started to dissipate heat to the air to meet the heat balance of the entire system.
[0033] The present utility model is a revolutionary design for traditional crude oil pipeline heating devices, adopting a variety of new energy coupling technologies, namely light energy, green electricity and energy storage. Through logical control technology and priority algorithms, a new type of device that cooperates with each other and timely utilizes light, electricity and energy storage is realized, achieving no carbon dioxide emissions and no toxic and harmful gas emissions for the whole set of devices, and saving costs. And the present utility model can avoid the excessive heat collected by the solar heat collection device 1 from causing the temperature of the crude oil in the oil pipeline 10 to be too high by setting the heat dissipation device 6, so as to maintain the heat balance of the photoelectric heating system.

[0036] See Figure 1 In some embodiments of the present utility model, a first one-way valve 3 is provided on the circulating liquid pipeline 11 between the outlet of the solar heat collection device 1 and the outlet of the heat exchange device 9, which can prevent the reverse flow of the circulating liquid, so that the circulating liquid can only flow unidirectionally from the outlet of the heat exchange device 9 to the solar heat collection device 1, facilitating the solar heat collection device 1 to heat the circulating liquid flowing out of the heat exchange device 9.
[0037] See Figure 1 In some embodiments of the present utility model, the oil pipeline 10 in the heat exchange device 9 is arranged in an S shape, extending the flowing time of the crude oil in the heat exchange device 9, increasing the heat exchange area with the circulating liquid in the heat exchange device 9, and improving the heating efficiency of the crude oil.
[0038] See Figure 1 In some embodiments of the present utility model, the energy storage device 5 includes a phase change energy storage device.
[0039] See Figure 1 In some embodiments of the present utility model, the crude oil photo-thermal heating system further includes a liquid supplement tank 7, and the outlet of the liquid supplement tank 7 is communicated with the circulating liquid pipeline 11 to ensure that there is a sufficient amount of circulating liquid flowing in the photo-thermal heating system for heat exchange.
[0040] See Figure 1 In some embodiments of the present utility model, the liquid supplement tank 7 is arranged between the heat dissipation device 6 and the inlet of the heat exchange device 9.
[0041] See Figure 1 In some embodiments of the present utility model, a second one-way valve 8 is provided between the outlet of the liquid supplement tank 7 and the circulating liquid pipeline 11, so that the circulating liquid can only be unidirectionally supplemented from the liquid supplement tank 7 into the circulating liquid pipeline 11 and will not flow back from the circulating liquid pipeline 11 into the liquid supplement tank 7.
