Description

Technical Field

[0001] This utility model belongs to the field of steam boiler technology, and in particular relates to a graphene electric heating steam boiler. Background Technology

[0002] As a crucial energy conversion device, the core function of a boiler is to efficiently convert input energy (such as the chemical energy of fuel, electrical energy, or the thermal energy of high-temperature flue gas) into a usable heat energy carrier, such as steam, high-temperature water, or organic heat carriers. Among the many types of boilers, electrically heated steam boilers are widely used in various fields, including industrial processing, food production, medical sterilization, building heating, and domestic services, due to their advantages such as cleanliness, environmental friendliness, ease of operation, and suitability for automation. These boilers typically use electricity to directly heat water inside the boiler, causing it to vaporize and produce the required steam.

[0003] Currently, most mainstream electric heating steam boilers on the market use traditional resistance wires or metal heating tubes as their core heating elements. However, these traditional heating technologies have gradually revealed a series of significant technical bottlenecks in long-term practical application. First, their electrothermal conversion efficiency is relatively low; a large amount of electrical energy is not effectively converted into heat energy for water heating, but is lost in other forms, resulting in high energy consumption and high operating costs. Second, traditional resistance wires or heating tubes have limitations in structural design and service life. Working in high-temperature and high-humidity environments for extended periods, they are prone to oxidation, scaling, aging, and even burnout. This not only causes uneven heating and affects the stability of steam quality but also increases the frequency of equipment maintenance and replacement costs. More importantly, due to the limitations of the material's thermal conductivity and heating method, the speed at which heat is transferred from the element to the water and ultimately generates steam is slow, resulting in a long start-up preheating time. This makes it difficult to meet the needs of some production or application scenarios with large fluctuations in steam demand and requiring rapid steam supply, affecting the overall system's operating efficiency and flexibility.

[0004] Therefore, there is an urgent need for a graphene-electrically heated steam boiler with high heating efficiency, low energy consumption, and fast and stable steam supply. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a graphene-electrically heated steam boiler that significantly improves heating efficiency and energy utilization, reduces operating energy consumption, achieves faster thermal response and steam generation capacity, and meets the requirements of modern production and service for efficient, immediate, and stable steam supply.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A graphene-based electrically heated steam boiler, comprising: The boiler body has a water storage chamber and a steam chamber inside. The steam chamber is located above the water storage chamber, and a steam passage connects the water storage chamber and the steam chamber. A steam output valve is provided at the upper end of the boiler body, and the steam output valve is connected to the steam chamber for outputting steam from the steam chamber; The control box is located on one side of the boiler body; A graphene heating device is installed inside the boiler body.

[0011] Furthermore, a water inlet mechanism is provided on one side of the boiler body. The water inlet mechanism includes a water tank and a water pump connected to the water tank. The water pump is used to input the water in the water tank into the water storage chamber through the water inlet pipe. The water tank is provided with a water inlet valve.

[0012] Furthermore, the water tank is equipped with a float.

[0013] Furthermore, a water level gauge connected to the water storage chamber is provided on one side of the boiler body, and a temperature sensor is provided in the steam chamber.

[0014] Furthermore, the boiler body is equipped with a pressure gauge and a pressure relief mechanism on its top.

[0015] Furthermore, the bottom of the boiler body is provided with a drain pipe connected to the water storage chamber.

[0016] The beneficial effects of this utility model are: This invention utilizes a graphene heating device to directly heat water using the high-efficiency electrothermal conversion properties of graphene, significantly improving steam generation speed and energy utilization efficiency. By incorporating a prismatic heating end, the effective contact area between the heating element and the water is increased.

An automated, quantitative water replenishment mechanism is implemented for the water storage cavity. A water level gauge enables real-time, visual monitoring of the water level in the storage cavity. A pressure gauge and pressure relief structure on the top of the boiler prevent overpressure risks.

[0022] See appendix Figure 1 To be continued Figure 4 The figure shows a specific embodiment of the graphene electric heating steam boiler provided by this utility model.

[0023] See appendix Figure 1 Graphene-heated steam boilers include: The boiler body 1 has a water storage chamber 110 and a steam chamber 120 inside. The steam chamber 120 is located above the water storage chamber 110, and a steam passage 130 connects the water storage chamber 110 and the steam chamber 120. A steam output valve 2 is located at the upper end of the boiler body 1. The steam output valve 2 is connected to the steam chamber 120 and is used to output the steam in the steam chamber 120. Control box 3 is located on one side of boiler body 1; A graphene heating device 4 is installed inside the boiler body 1. The graphene heating device 4 includes a heating end 410 and a circuit connection end 420. The heating end 410 extends into the water storage chamber 110, and the circuit connection end 420 is connected to the control box 3.

[0024] See appendix Figure 2 In the above embodiment, the boiler body 1 is provided with a water storage chamber 110, a steam channel 130, and a steam chamber 120 from bottom to top. The control box 3 is equipped with a control panel 310, which allows the user to view the boiler's operating status and control its operation. During use, the user operates the control panel 310 to power on the graphene heating device 4. The heating end 410 of the graphene heating device 4 heats up rapidly under the influence of the current. The generated heat is quickly transferred to the water in the water storage chamber 110 through the metal substrate of the graphene heating device 4, heating the water. As the water temperature rises, the water gradually vaporizes into steam. The steam enters the steam chamber 120 through the steam channel 130, and the steam in the steam chamber 120 is delivered to the steam-using equipment through the steam output valve 2. This embodiment utilizes the highly efficient electrothermal conversion characteristics of graphene material to directly heat water. Compared with traditional heating elements, this significantly improves the steam generation speed and energy utilization efficiency, ensuring stable steam output. Graphene material has good chemical stability and physical properties, is not easily aged or damaged, has a longer service life, and reduces equipment maintenance and replacement costs.

[0025] See appendix Figure 4 In the above embodiment, the heating end 410 has a prism-shaped structure and is horizontally positioned within the water storage cavity 110. In this embodiment, the heating end 410 has a triangular prism structure. Additionally, this embodiment includes six graphene heating devices 4, distributed in three different height layers within the water storage cavity 110. Two graphene heating devices 4 are installed in each height layer. Under the control of the control box 3, different positions and numbers of graphene heating devices 4 can be activated according to the water level in the water storage cavity 110, increasing the effective contact area between the heating element and the water and improving heating efficiency.

[0026] See appendix Figure 4 In the above embodiments, the graphene heating device 4 includes multiple graphene heating plates 430 forming the side of the heating end 410. The metal substrate of the graphene heating plate 430 is located on the outside of the heating end 410, and the graphene heating layer of the graphene heating plate 430 is located on the inside of the heating end. In each embodiment, each graphene heating device 4 is provided with three graphene heating plates 430 assembled into a triangular prism structure. Adjacent graphene heating plates 430 are connected and fixed by welding. The end of the heating end 410 is provided with a sealing plate 440 to construct a sealed and reliable integrated heating cavity, preventing water from seeping into the internal circuit, ensuring electrical safety and extending service life.

[0027] See appendix Figure 4In the above embodiments, the graphene heating device 4 further includes a flange 450 disposed between the heating end 410 and the circuit connection end 420, for fixing the graphene heating device 4 to the boiler body 1. In the embodiments, the flange 450 is fixed to the inside of the control box 3, the circuit connection end 420 is located inside the control box 3, and the heating end 410 passes through the side shell of the boiler body 1 and connects to the water storage chamber 110.

[0028] See appendix Figure 2 In the above embodiment, a water inlet mechanism 5 is also provided on one side of the boiler body 1. The water inlet mechanism 5 includes a water tank 510 and a water pump 520 connected to the water tank 510. The water pump 520 is used to input water in the water tank 510 into the water storage chamber 110 through the water inlet pipe 530. The water tank 510 is provided with a water inlet valve 512 and a float ball 511. A water level gauge 6 connected to the water storage chamber 110 is also provided on one side of the boiler body 1, and a temperature sensor is provided in the steam chamber 120. In this embodiment, the water inlet mechanism 5 realizes automated quantitative water replenishment of the water storage chamber 110, maintains continuous steam production capacity, and reduces manual intervention. The float ball 511 in the water tank 510 facilitates automatic monitoring and control of the water level in the water tank 510, prevents the water pump 520 from running dry and being damaged, and improves system reliability.

[0029] See appendix Figure 2 and attached Figure 3 In this embodiment, during use, the user sets the required steam temperature and water level parameters via the control panel 310. The control system in the control box 3 starts the water pump 520. The water pump 520 injects water into the water storage chamber 110 through the water inlet pipe 530. The water level gauge 6 monitors the water level in real time through the water level sensor in the water storage chamber 110. When the water level reaches the preset value, the water pump 520 stops working. Then, the control box 3 controls the graphene heating plate 430 of the graphene heating device 4 to be powered on and heated. The heat from the graphene heating plate 430 is transferred to the water through the metal substrate to heat the water. As the water temperature rises, the water gradually vaporizes into steam, and the steam enters the steam chamber 12 through the steam channel 130. 0; The temperature sensor in the steam chamber 120 monitors the steam temperature in the steam chamber 120 in real time and feeds the temperature signal back to the control box 3. When the steam temperature reaches the set value, the control box 3 adjusts the heating power of the graphene heating device 4 according to the actual situation to maintain the stability of the steam temperature. The user can control the opening and closing of the steam output valve 2 through the control panel 310 to adjust the output flow and pressure of the steam and deliver the steam to the steam-using equipment. When the water level in the water storage chamber 110 drops to a certain level, the water level sensor of the water level gauge 6 transmits the signal to the control box 3. The control box 3 starts the water pump 520 to inject water into the water storage chamber 110 again to ensure the continuous operation of the steam boiler.

[0030] See appendix Figure 1In the above embodiment, a pressure gauge 7 and a pressure relief mechanism 8 are provided on the top of the boiler body 1. The pressure gauge 7 is connected to the water storage chamber 110, and the pressure relief mechanism 8 includes a first pressure relief valve 810 and a second pressure relief valve 820. The first pressure relief valve 810 is connected to the water storage chamber 110, and the second pressure relief valve 820 is connected to the steam chamber 120. In this embodiment, the design of the dual pressure relief valves helps to avoid the risk of overpressure. The pressure gauge 7 is connected to the water storage chamber 110 to monitor pressure changes in real time, ensuring safe use.

[0031] See appendix Figure 2 In the above embodiment, the bottom of the boiler body 1 is provided with a drain pipe 9 connected to the water storage chamber 110, which facilitates the complete drainage of residual scale or impurities in the water storage chamber 110 and simplifies the maintenance process.

[0032] In summary, this embodiment provides a graphene-electrically heated steam boiler. By setting up a graphene heating device 4, it achieves direct heating of water using the high-efficiency electrothermal conversion characteristics of graphene material, significantly improving steam generation speed and energy utilization efficiency. By setting up a prismatic heating end 410, the effective contact area between the heating element and the water is increased. By welding and fixing adjacent graphene heating plates 430 and setting a sealing bottom plate 440 at the end, a sealed and reliable integrated heating cavity is constructed to prevent water from seeping into the internal circuit. By configuring a water inlet mechanism 5, the water storage cavity 110 is automatically and quantitatively replenished. By setting up a water level gauge 6, the water level in the water storage cavity is monitored in real time. By setting up a pressure gauge 7 and a pressure relief structure on the top of the boiler, the risk of overpressure is avoided. By setting up a drain pipe 9, residual scale or impurities in the water storage cavity 110 are easily drained. This embodiment significantly improves heating efficiency and energy utilization, reduces operating energy consumption, achieves faster thermal response speed and steam generation capacity, and meets the requirements of modern production and service for efficient, immediate, and stable steam supply.
