[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in the fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated over fire, and "furnace" refers to a place for burning fuel. The boiler includes two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1 - 3 , an embodiment provided by the present invention: an energy-saving and efficient boiler, including a boiler jacket 1, the bottom of the outer wall of the boiler jacket 1 is fixedly connected with a base 2, the furnace door 3 is rotatably connected inside the boiler jacket 1, the observation window 4 is fixedly connected inside the boiler jacket 1, the top cover 5 is fixedly connected to the top of the outer wall of the boiler jacket 1, the chimney 6 is fixedly connected inside the top cover 5, the first water inlet 7 is fixedly connected inside the boiler jacket 1, the first water outlet 8 is fixedly connected inside the boiler jacket 1, the main boiler 9 is fixedly connected inside the boiler jacket 1, the auxiliary boiler 10 is fixedly connected inside the main boiler 9, the pressure gauge 11 is fixedly connected to the outer wall of the boiler jacket 1, the circulation pump 12 is arranged on the outer wall of the boiler jacket 1, the output end of the circulation pump 12 is fixedly connected with a connecting pipe 13, and a water outlet assembly is arranged inside the main boiler 9, and the water outlet assembly is used for discharging the water flowing in the auxiliary boiler 10; the water outlet assembly includes a connecting pipe 18, the outer wall of the connecting pipe 18 is fixedly connected inside the main boiler 9, and a check valve 19 is fixedly connected inside the connecting pipe 18; the outer wall of the first water inlet 7 penetrates into the auxiliary boiler 10, and the outer wall of the first water outlet 8 penetrates into the main boiler 9; both ends of the connecting pipe 13 are fixedly connected inside the boiler jacket 1, and the inside of the circulation pump 12 is fixedly connected to the outer wall of the connecting pipe 13;

[0023] Specifically, when it is necessary to fully absorb and utilize the heat energy in the hot gas discharged from the boiler interior, cold water enters the interior of the secondary boiler 10 through the first water inlet 7. Inside the secondary boiler 10, the cold water circulates around its structure. During this process, the cold water gradually absorbs the heat inside the secondary boiler 10. This circulating flow effectively transfers the heat energy to the cold water and raises the temperature of the cold water. Next, the heated water flows into the interior of the main boiler 9 through the connecting pipe 18. Inside the main boiler 9, the water continues to circulate along the boiler pipes to further absorb the heat energy in the hot gas discharged from the main boiler 9. This process ensures the effective utilization and transfer of heat energy. During the whole process, the one-way valve 19 can prevent the already heated water from flowing back into the interior of the secondary boiler 10, ensuring the one-way flow of heat energy between the main boiler 9 and the secondary boiler 10. Finally, the hot water released through the first water outlet 8 achieves the effect of fully absorbing and utilizing the heat in the hot gas.

[0024] Refer to Figures 1 - 3 , a second water outlet pipe 14 is fixedly connected inside the boiler jacket 1, and the outer wall of the second water outlet pipe 14 penetrates into the interior of the secondary boiler 10; a second water inlet pipe 17 is fixedly connected inside the boiler jacket 1, and the outer wall of the second water inlet pipe 17 penetrates into the interior of the main boiler 9; threaded pipes 15 are fixedly connected to the outer walls of both the second water outlet pipe 14 and the second water inlet pipe 17, and a mounting pipe 16 is threadedly connected to the outer wall of the threaded pipe 15; the second water outlet pipe 14 and the second water inlet pipe 17 are in contact with each other, and the interior of the mounting pipe 16 is rotatably connected to the outer wall of the second water inlet pipe 17;

[0025] Specifically, when it is necessary to make more full use of the heat energy inside the boiler, by connecting the second water outlet pipe 14 and the second water inlet pipe 17, using the mounting pipe 16 to close, and injecting cold water into the first water inlet 7, this enables the cold water to continue to flow around the secondary boiler 10. The cold water inside the secondary boiler 10 gradually absorbs the heat released inside the secondary boiler 10 during the circulation, raising the temperature of the cold water. Subsequently, the heated water flows out of the interior of the boiler jacket 1 through the second water outlet pipe 14. This step ensures that the heated water can effectively transfer the heat it carries to the surrounding environment of the boiler jacket 1. Next, the heated water is re-injected back into the interior of the main boiler 9 through the second water inlet pipe 17. Inside the main boiler 9, the water continues to circulate, enabling the main boiler 9 to effectively utilize the hot gas inside it, thereby further improving the utilization efficiency of the heat energy.

[0026] Working principle: When it is necessary to absorb the heat energy in the hot gas discharged from the inside of the boiler, a secondary boiler 10 is installed inside the main boiler 9, so that cold water can be sent into the inside of the secondary boiler 10 from the first water inlet 7, enabling the cold water to circulate inside the secondary boiler 10 and then flow into the inside of the main boiler 9 through the connecting pipe 18. The one-way valve 19 can prevent the cold water from flowing back into the secondary boiler 10, and then circulate around the main boiler 9, and finally hot water is discharged out from the first water outlet 8, thereby achieving the effect of fully absorbing and utilizing the heat contained in the hot gas, improving the thermal efficiency of the boiler. Then, the second water outlet pipe 14 and the second water inlet pipe 17 are connected through the installation pipe 16, so that the second water outlet pipe 14 and the second water inlet pipe 17 can be closed. At the same time, cold water is injected into the first water inlet 7, enabling the cold water to continue to flow around the secondary boiler 10, then flow out of the inside of the boiler jacket 1 through the second water outlet pipe 14, and then be re-injected into the inside of the main boiler 9 through the second water inlet pipe 17. After the circulation in the main boiler 9 is completed, it is finally discharged out from the first water outlet 8, thereby achieving the effect of more fully and evenly distributing the hot gas and the cold water, further increasing the absorption of the heat in the hot gas, and improving the practicability of the hot furnace.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
