Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and in particular to an energy-saving and high-efficiency boiler based on carbon fiber heating. Background Technology

[0002] A boiler is an energy conversion device that heats water into hot water or steam at a certain temperature and pressure by inputting energy in the form of fuel or electricity into the boiler and through processes such as combustion or electric heating inside the boiler, providing heat or power for industrial production and domestic life.

[0003] However, in traditional boiler designs, the heated water does not circulate easily within the boiler, resulting in structural defects such as insufficient water contact area, a single heat exchange path, and uneven heating, leading to poor actual energy-saving effects.

[0004] To address these issues, we propose an energy-efficient boiler based on carbon fiber heating. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving and efficient boiler based on carbon fiber heating to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An energy-efficient boiler based on carbon fiber heating includes a furnace body, a furnace cover, an inlet pipe, and an outlet pipe, and also includes a heating core. The furnace body includes an inner furnace cylinder and a first carbon fiber heating wire uniformly wound on the outer wall of the inner furnace cylinder. The heating core is installed in the center of the inner furnace cylinder, and a spiral partition is installed between the heating core and the inner furnace cylinder. The spiral partition divides the space between the heating core and the inner furnace cylinder into a spiral channel. The heating core includes a heat collection cylinder and a second carbon fiber heating wire uniformly wound on the inner wall of the heat collection cylinder.

[0008] In a further embodiment, the furnace body also includes a furnace body insulation layer and a furnace body outer shell distributed sequentially from the inside to the outside, and the furnace body insulation layer wraps around the outer side of the carbon fiber heating wire.

[0009] In a further embodiment, the gap between the furnace body insulation layer and the inner furnace cylinder is filled with thermally conductive silicone grease.

[0010] In a further embodiment, the furnace cover includes a furnace cover insulation layer and a furnace cover outer shell distributed sequentially from the inside to the outside.

[0011] In a further embodiment, the heating core further includes a heat insulation layer, which is distributed on the inner side of the carbon fiber heating wire II, and the gap between the heating core and the heat insulation layer is filled with thermally conductive silicone grease.

[0012] In a further embodiment, the spiral partition has a cavity inside, and the inner wall of the heating core has a perforation communicating with the cavity, and the carbon fiber heating wire passes through the cavity and the perforation.

[0013] In a further embodiment, the gaps in the cavity are filled with thermally conductive silicone grease.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention heats water simultaneously on both the inner and outer sides by setting an inner furnace cylinder and a heat collection cylinder, respectively, to achieve bidirectional heat radiation. Furthermore, the water flows through a spiral channel formed by spiral partitions, which effectively increases the water flow contact area, thereby improving heating efficiency, making the heating more uniform, reducing heat loss, and achieving better energy-saving results.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 An energy-efficient boiler based on carbon fiber heating includes a boiler body 1. Specifically, the boiler body 1 adopts a cylindrical double-layer structure, including an inner boiler cylinder 11 and carbon fiber heating wires 12 uniformly wound on the outer wall of the inner boiler cylinder 11. The inner boiler cylinder 11 is made of metal. The carbon fiber heating wires 12 are arranged in a spiral shape and fixed with high-temperature resistant adhesive. It also includes a boiler body insulation layer 13 and a boiler body outer shell 14 distributed from the inside to the outside. The boiler body insulation layer 13 is wrapped around the outside of the carbon fiber heating wires 12. The boiler body insulation layer 13 is made of rock wool or glass fiber. The gap between the boiler body insulation layer 13 and the inner boiler cylinder 11 is filled with thermally conductive silicone grease to ensure efficient heat transfer to the inner boiler cylinder 11. The boiler body outer shell 14 is a metal protective layer that covers the outside of the insulation layer. The surface is provided with heat dissipation holes to balance the internal pressure.

[0024] The energy-efficient boiler also includes a heating core 6, which is installed in the center of the inner furnace cylinder 11. The heating core 6 includes a heat collection cylinder 61, carbon fiber heating wires 62 evenly wound on the inner wall of the heat collection cylinder 61, and a central insulation layer 63. The heat collection cylinder 61 is a metal cylinder, the carbon fiber heating wires 62 are distributed in a ring and fixed with high-temperature resistant adhesive, and the insulation layer 63 is attached to the inner side of the carbon fiber heating wires 62. It is made of ceramic fiber or aerogel and filled with thermally conductive silicone grease between it and the heating wires to ensure that heat is concentrated in the heat collection cylinder 61. A spiral partition 7 is also installed between the heating core 6 and the inner furnace cylinder 11. The spiral partition 7 is a thin metal sheet that is spirally welded between the inner furnace cylinder 11 and the heating core 6, dividing the gap between the two into a spiral channel. Water flows along this channel to form a vortex and extend the heating path.

[0025] Furthermore, the spiral partition 7 has a cavity 71 inside, which runs through the entire length of the partition and is filled with thermally conductive silicone grease. The heat collection cylinder 61 of the heating cylinder core 6 has a perforation 611 on its side wall. The carbon fiber heating wire 62 passes through the perforation 611 and enters the cavity 71. In the cavity 71, the heating wire is distributed in a serpentine pattern to achieve heat conduction between the heating wire and the spiral partition 7, so that heat exchange can occur around it when water flows through.

[0026] The energy-efficient boiler also includes a furnace cover 2, an inlet pipe 3, and an outlet pipe 4. The furnace cover 2 includes a furnace cover insulation layer 21 and a furnace cover shell 22 from the inside out. The furnace cover insulation layer 21 is made of the same material as the furnace body insulation layer 13. The furnace cover shell 22 is made of metal and its edges are sealed to the furnace body shell 14 by bolts. The inlet pipe 3 and the outlet pipe 4 are welded to the bottom and top of the furnace body 1, respectively. The inlet pipe 3 is connected to the spiral channel inlet, and the outlet pipe 4 is connected to the spiral channel outlet, forming a unidirectional water flow circulation. Furthermore, both the inlet pipe 3 and the outlet pipe 4 are equipped with control valves 5 to facilitate the control of the pipe opening and closing.

[0027] To facilitate the control of the water heating temperature inside the boiler, temperature probes 8 are installed at the inlet of the water inlet pipe 3 and the outlet of the water outlet pipe 4 to detect the initial temperature of the cold water and provide feedback on the final heating temperature. Both the temperature probes 8 and the heating wires are connected to a PLC controller via waterproof terminals. The PLC controller can be installed in a control box on the side wall of the boiler shell 14. It receives sensor signals and automatically adjusts the input current of the carbon fiber heating wire 12 and the carbon fiber heating wire 62 through PWM or voltage modulation to control the heating power. At the same time, it presets the target heating temperature and adjusts the output in real time according to the water temperature change to avoid overshoot or energy waste. The PLC controller and the control box are not shown in the figure.
