Description

Technical Field

[0001] This utility model relates to the field of steam preparation technology, and in particular to a graphene heating element steam generator. Background Technology

[0002] Currently, steam generators, also commonly referred to as boilers, are devices that convert the chemical or electrical energy of fuel into thermal energy to produce steam. Steam generators are widely used in various fields such as power generation, industrial processing, heating, and marine propulsion. They heat the furnace by burning fuel inside, which in turn heats water to produce steam.

[0003] In traditional steam generators, water is concentrated in the upper part of the furnace for heating. The heat on the side walls of the furnace cannot be absorbed by heat exchange and the hot air is radiated to the outside through the furnace walls, resulting in energy waste and reducing the energy utilization rate of the heat generated in the furnace.

[0004] To address this, existing technology (Publication No.: CN223153541U, Publication Date: 2025.07.25) discloses a steam generator. Its design between the furnace and heating jacket increases the contact area between water and the furnace, improving heat exchange efficiency and accelerating water boiling and evaporation. The flue gas chamber design allows the flue gas to reheat the water in the heating jacket, lowering the flue gas temperature and preheating the water in the preheating chamber. Through the design of the air guide plate and flue gas inlet, the flue gas is effectively guided and discharged, reducing heat loss and improving fuel utilization.

[0005] However, the above scheme requires a preheating chamber to be set on the outside of the furnace body and a complex structure such as a furnace chamber and stirring rod to be set inside the furnace body. Its manufacturing cost is high and it occupies a lot of space. Therefore, it is necessary to redesign the steam generator so that it can achieve sufficient heat exchange within the original volume, while also ensuring that the water is fully heated to generate steam stably. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0007] A graphene heating element steam generator includes a furnace body, in which a plurality of atomizing tubes are fixedly installed. A flue gas inlet and a flue gas outlet are formed on the outer side of the furnace body, and heat exchange gaps are left between the plurality of atomizing tubes. The lower ends of several atomizing tubes are connected to a base plate, a water storage tank is formed inside the base plate, a water inlet pipe is connected to the bottom side of the base plate, and the upper ends of several atomizing tubes are connected to a top plate, an atomizing groove is formed inside the top plate, and an atomizing port is connected to the top of the top plate. A heating rod is inserted and fitted into the upper end of the atomizing tube; A flow reduction component is fixedly installed at the bottom of the atomizing tube, and water is transported from the water storage tank to the atomizing tube after passing through the flow reduction component.

[0008] Furthermore: the flow reduction component includes a positioning post and a spiral edge. The upper and lower ends of the positioning post are both formed with positioning discs, which are fixedly installed in the atomizing tube. The spiral edge is integrally formed on the outside of the positioning post, and the outer edge of the spiral edge abuts against the atomizing tube.

[0009] Furthermore, several water-passing micro-holes are formed on the positioning discs at both the upper and lower ends.

[0010] Furthermore, a first filter screen is fixedly installed inside the water storage tank of the chassis.

[0011] Furthermore: a second filter screen is fixedly installed in the atomizing groove of the top plate, and the upper end of the heating rod is fixedly installed on the bottom side of the second filter screen.

[0012] Furthermore, a water delivery gap is left between the outer wall of the heating rod and the atomizing tube.

[0013] Furthermore, a positioning ring is fixedly installed on the outer side of the bottom end of the heating rod. The diameter of the positioning ring is larger than the diameter of the heating rod, and the positioning ring is installed in the atomizing tube with a clearance fit.

[0014] Furthermore, the heating rod uses a graphene heating element.

[0015] Furthermore: the flue gas inlet is located on the outer side of the lower end of the atomizing tube, and the flue gas outlet is located on the outer side of the upper end of the atomizing tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: water is transported to the water storage tank in the chassis through the water inlet pipe, and then the water is transported to the bottom of the atomizing tube after passing through the flow reduction component. The flow reduction component can reduce the water flow rate, thereby ensuring the residence time of the water in the atomizing tube. At this time, high-temperature flue gas is transported to the flue gas inlet. The high-temperature flue gas will preheat the water in the atomizing tube. Due to the flow reduction component, sufficient heat exchange between the flue gas and the water can be achieved, effectively reducing the output temperature at the flue gas outlet. At the same time, the water in the atomizing tube is preheated and then transported to the upper end of the atomizing tube. Since the heating rod can further heat the water in the atomizing tube, the water flow can be fully vaporized.

[0026] like Figure 1-5 As shown, the present invention provides a graphene heating element steam generator, which includes a furnace body 1. Several atomizing tubes 2 are fixedly installed inside the furnace body 1. A flue gas inlet 3 and a flue gas outlet 4 are formed on the outer side of the furnace body 1. A heat exchange gap 5 is left between the several atomizing tubes 2. The lower ends of several atomizing tubes 2 are connected to a base plate 6, a water storage tank 7 is formed inside the base plate 6, a water inlet pipe 8 is connected to the bottom side of the base plate 6, and the upper ends of several atomizing tubes 2 are connected to a top plate 9, an atomizing groove 10 is formed inside the top plate 9, and an atomizing port 11 is connected to the top of the top plate 9. A heating rod 12 is inserted and fitted into the upper end of the atomizing tube 2; A flow reduction component 13 is fixedly installed at the bottom of the atomizing tube 2, and water is transported from the water storage tank 7 to the atomizing tube 2 after passing through the flow reduction component 13. The principle is as follows: water is supplied from the inlet pipe 8 to the water storage tank 7 in the chassis 6. After passing through the flow reduction component 13, the water is supplied to the bottom of the atomizing tube 2. The flow reduction component 13 can reduce the water flow rate, thereby ensuring the residence time of the water in the atomizing tube 2. At this time, high-temperature flue gas is supplied to the flue gas inlet 3. The high-temperature flue gas will preheat the water in the atomizing tube 2. Due to the flow reduction component 13, sufficient heat exchange between the flue gas and the water can be achieved, effectively reducing the output temperature at the flue gas outlet 4. At the same time, the water in the atomizing tube 2 is preheated and then supplied to the upper end of the atomizing tube 2. Since the heating rod 12 can further heat the water in the atomizing tube 2, the water can be fully vaporized.

[0027] Furthermore, the flow reduction component 13 includes a positioning post 131 and a spiral edge 132. Positioning discs 14 are formed at both the upper and lower ends of the positioning post 131. The positioning discs 14 are fixedly installed in the atomizing tube 2. The spiral edge 132 is integrally formed on the outside of the positioning post 131, and the outer edge of the spiral edge 132 abuts against the atomizing tube 2. The water flow will first pass through the bottom positioning disc 14, be transported around the spiral edge 132, and then enter the bottom of the atomizing tube 2 through the top positioning disc 14, thereby effectively slowing down the water flow speed, increasing the residence time of the water flow in the atomizing tube 2, and achieving sufficient heat exchange between the high-temperature flue gas and the water flow.

[0028] Furthermore, several water-passing micro-holes 15 are formed on the positioning discs 14 at both the upper and lower ends; the water flows through the water-passing micro-holes 15, which can effectively slow down the water flow rate and ensure sufficient heat exchange.

[0029] Furthermore, a first filter screen 16 is fixedly installed in the water storage tank 7 of the chassis 6; it can effectively filter impurities in the water flow and ensure the cleanliness of the water vaporization.

[0030] Furthermore: a second filter screen 17 is fixedly installed in the atomizing groove 10 of the top plate 9, and the upper end of the heating rod 12 is fixedly installed on the bottom side of the second filter screen 17; this can effectively filter steam for output, while ensuring the precise positioning of the heating rod 12 in the atomizing tube 2.

[0031] Furthermore, a water supply gap 18 is provided between the outer wall of the heating rod 12 and the atomizing tube 2; water can pass through this water supply gap 18 to be heated and vaporized, achieving the effect of full vaporization.

[0032] Furthermore, a positioning ring 19 is fixedly installed on the outer side of the bottom end of the heating rod 12. The diameter of the positioning ring 19 is larger than the diameter of the heating rod 12. The positioning ring 19 is installed in the atomizing tube 2 with a clearance fit. This can effectively reduce the flow rate of the water, thereby allowing the heating rod 12 to fully heat the water and achieve the effect of full vaporization.

[0033] Furthermore, the heating rod 12 is a graphene heating element; graphene has excellent electrical conductivity and thermal conductivity, enabling the water to be fully vaporized.

[0034] Furthermore, the flue gas inlet 3 is located on the outer side of the lower end of the atomizing tube 2, and the flue gas outlet 4 is located on the outer side of the upper end of the atomizing tube 2; thus achieving a sufficient heat exchange effect.

[0035] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
