[0037] Embodiment 2:

[0038] On the basis of Embodiment 1, its specific working principle is as follows:

[0039] In this green power consumption steam energy storage system for oil heating, oil enters the inside of the heat exchange tube 13 through the connecting sleeves 14 at both ends of the heating box 9. At the same time, high-temperature steam is introduced into the heating box 9 through the air inlet 10. When the oil flows inside the heat exchange tube 13, the high-temperature steam inside the heating box 9 will contact the heat exchange tube 13 at this time, and the high-temperature steam will conduct heat into the heat exchange tube 13, thereby heating the oil inside the heat exchange tube 13. Through the equidistant arrangement of multiple heat exchange tubes 13 inside the heating box 9, and the heat exchange tubes 13 are distributed in an S-shaped structure inside the heating tubes 19, the surface area of the heat exchange tubes 13 inside the heating box 9 is increased, so as to increase the contact area between the heat exchange tubes 13 and the steam, and then improve the heating efficiency;

[0040] The filling block 12 arranged inside the heating box 9 limits the space inside the heating box 9, making the movement space of the steam inside the heating box 9 limited, making the steam inside the heating box 9 more concentrated, and then making the heat of the steam more concentrated, improving the heating efficiency of the heat exchange tube 13 and the oil inside it;

[0041] A hollow cavity is formed between the heating box 9 and the heating furnace 1 to prevent the heat inside the heating box 9 from being lost by medium transmission to the outside of the heating furnace 1. And mirror materials are arranged on the outside of the filling block 12 and the inside of the heating box 9 to prevent the heat inside the heating box 9 from being lost in the form of thermal radiation, making the heat inside the heating box 9 more concentrated and improving the heating efficiency of the heat exchange tube 13 and the oil inside it;

[0042] When water is inside the steam tank 2, the electric heating wire 20 is electrified at this time. The electric heating wire 20 transmits heat to the inside of the steam tank 2 through the heating tube 19, thereby heating the water inside the steam tank 2. The heated water generates steam, and the steam enters the top of the isolation plate 17 through the through hole 18. When the steam inside the steam tank 2 reaches a certain pressure, the pressure valve 5 will be in a connected state at this time, and the steam inside the steam tank 2 will enter the heating box 9 through the air duct 3;

[0043] The steam that has been heated inside the heating box 9 will form condensed water, and the condensed water enters the water collection port 6 through the water outlet 11 at the bottom of the heating box 9. The one-way valve 8 is provided to prevent the water in the return pipe 4 from flowing back into the heating box 9 due to excessive pressure inside the steam tank 2.
