Description
Technical Field
[0001] This utility model relates to the field of steam generators, and specifically to a steam generator with a flow guiding structure. Background Technology
[0002] A steam generator is a mechanical device that heats water or other fluids to a temperature that produces steam and converts them into steam. It is commonly known as a boiler. The working principle of a steam generator is mainly based on energy conversion and heat transfer processes. Taking common electric heating steam generators and gas-fired steam generators as examples: Electric heating steam generators: Power is supplied to the heating element. When the resistance wire is energized, it generates a large amount of heat energy. This heat energy is transferred to the water in the water tank, causing the water temperature to gradually rise. When the water temperature reaches the boiling point, it begins to vaporize and form water vapor. In this process, there are usually pressure control devices and water level control devices to ensure that the steam generator operates within a safe pressure and water level range. Gas-fired steam generators: Gas is burned in the combustion chamber to produce high-temperature flue gas. This high-temperature flue gas transfers heat to the water through heat exchange, causing the water to be heated and vaporized to produce steam.
[0003] A search revealed a steam generator with a flow guiding structure, disclosed in announcement number CN220303613U. The steam generator includes a main body, with a flow guiding pipe fixedly installed on the outer wall of the right end of the main body. Two sets of limiting ring plates are fixedly installed on the inner wall of the flow guiding pipe. A cleaning device is located at the upper end of the flow guiding pipe, comprising a drive motor, a bevel gear A, a threaded rod, a bevel gear B, a threaded slider, a fixed cylinder, a support rod, a cleaning scraper, and a telescopic spring. This steam generator with a flow guiding structure, through the cleaning device, drives the cleaning scraper to clean the inner wall of the flow guiding pipe, preventing scale buildup and extending the equipment's service life. The telescopic spring inside the fixed cylinder ensures the cleaning scraper fits more closely to the inner wall of the flow guiding pipe, improving the cleaning effect.
[0004] In the operation of existing steam generators, the flow guiding structure of the steam generator only guides the incoming water. This lack of flow guiding structure during internal preheating and steam separation leads to a decrease in thermal efficiency and a decline in steam quality. Furthermore, the flow guiding structure of the steam generator in the comparative case mentioned above is also too simple. With long-term use, the steam discharge speed will slow down, which will also affect the response speed of the steam generator.
[0005] Therefore, it is necessary to invent a steam generator with a flow guiding structure to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a steam generator with a flow-guiding structure. This structure is achieved through a preheating combustion chamber, a preheating main pipe, a water inlet pipe, a spiral guide plate, a water-gas separation chamber, a splash plate, a first baffle separator, and a second baffle separator. This flow-guiding structure design allows the water flow to more fully absorb the heat generated in the combustion chamber, thereby improving thermal efficiency. The splash plate then performs initial separation of the heated water vapor, while the first and second baffle separators further separate steam and water molecules. This multi-stage separation design ensures that the output steam has a higher dryness, meeting the requirements for high-quality steam. Furthermore, the design of the gradually tapering flue, wider at the bottom and narrower at the top, utilizes the Venturi effect to accelerate the steam discharge speed. This not only improves the response speed of the steam generator but also makes the steam discharge smoother, thus improving the overall efficiency. This addresses the problem in existing steam generators where the flow guiding structure only guides the incoming water, lacking internal preheating and steam separation mechanisms, leading to reduced thermal efficiency and decreased steam quality. Moreover, the flow guiding structure in the aforementioned comparative case is also too simplistic, which will slow down the steam discharge speed over long-term use and affect the response speed of the steam generator.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a steam generator with a flow guiding structure, comprising a steam generator body and a main body for generating steam;
[0008] The preheating combustion chamber is fixedly installed on the back of the steam generator body to improve the water heating speed. Fixing rings are fixedly installed on both sides of the interior of the preheating combustion chamber. The preheating main chamber pipe is fixedly installed inside the fixing rings. A water inlet pipe is fixedly installed at one end of the preheating main chamber pipe, and a water outlet pipe is fixedly installed at the other end of the preheating main chamber pipe. A spiral guide plate is fixedly installed inside the preheating main chamber pipe.
[0009] A transparent display cavity is fixedly connected to the other end of the water outlet pipe for observing the water outlet status. A water supply pipe is fixedly installed at the bottom of the transparent display cavity. A water-gas separation cavity is fixedly installed inside the steam generator body, and a splash guard is fixedly installed inside the water-gas separation cavity.
[0010] The first baffle separator is fixedly installed inside the water-gas separation chamber for guiding and separating steam. The exterior of the first baffle separator is provided with flue gas holes. A second baffle separator is fixedly installed above the first baffle separator. A fixing frame is fixedly installed above the water-gas separation chamber. Gradient flue pipes are fixedly installed inside the fixing frame.
[0011] Preferably, air intake pipes are fixedly installed on both sides of the back of the preheating combustion chamber, and an igniter is fixedly installed inside the preheating combustion chamber.
[0012] Preferably, the other end of the water supply pipe is fixedly connected to the water-air separation chamber, and the splash guard is configured with an L-shaped structure.
[0013] Preferably, a partition plate is fixedly installed inside the water-air separation chamber, and an electric heating tube is fixedly installed below each partition plate.
[0014] Preferably, the number of flue gas holes is set to multiple, and the multiple flue gas holes are distributed at equal intervals on the first baffle separator.
[0015] Preferably, a return pipe is fixedly installed at the top end of the gradient smoke pipe, and a smoke outlet pipe is fixedly installed at the top end of the return pipe.
[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0017] This invention comprises a preheating combustion chamber, a preheating main chamber pipe, a water inlet pipe, a spiral guide plate, a water-gas separation chamber, a splash plate, a first baffle separator, and a second baffle separator. After external water flows into the preheating main chamber pipe through the water inlet pipe, it is guided by the spiral guide plate inside the preheating main chamber pipe, causing the water flow to form a spiral turbine shape inside the preheating main chamber pipe. This increases the residence time of the water flow when the preheating combustion chamber preheats the preheating main chamber pipe. Then, when the preheated water flows into the water-gas separation chamber from the water supply pipe, it is first blocked by the splash plate, causing the heated water and vapor to separate. Then, as the steam rises, it encounters the first and second baffle separators, causing the steam and water molecules to separate again. The steam then flows upward through the flue gas vent. The steam then enters the gradient flue. Due to the design of the gradient flue, which is wider at the bottom and narrower at the top, the steam discharge speed is further accelerated. This combination gives the steam generator a flow guiding structure. This flow guiding structure design allows the water flow to absorb the heat generated in the combustion chamber more fully, thereby improving thermal efficiency. Then, the splash plate performs initial separation of the heated water vapor, while the first baffle separator and the second baffle separator further separate steam and water molecules. This multi-stage separation design ensures that the output steam has a higher dryness, meeting the requirements of high-quality steam. Moreover, the design of the gradient flue, which is wider at the bottom and narrower at the top, utilizes the Venturi effect to accelerate the steam discharge speed. This not only improves the response speed of the steam generator but also makes the steam discharge smoother, improving the overall efficiency. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The steam generator shown has a flow guiding structure, including a steam generator body 1, which is the main body for generating steam;
[0028] The preheating combustion chamber 2 is fixedly installed on the back of the steam generator body 1 to improve the water heating speed. Fixing rings 3 are fixedly installed on both sides of the interior of the preheating combustion chamber 2. The preheating main chamber pipe 4 is fixedly installed inside the fixing rings 3. A water inlet pipe 5 is fixedly installed at one end of the preheating main chamber pipe 4, and a water outlet pipe 6 is fixedly installed at the other end of the preheating main chamber pipe 4. A spiral guide plate 9 is fixedly installed inside the preheating main chamber pipe 4.
[0029] A transparent display cavity 10 is fixedly connected to the other end of the water outlet pipe 6 for observing the water outlet status. A water supply pipe 11 is fixedly installed at the bottom of the transparent display cavity 10. A water-air separation cavity 12 is fixedly installed inside the steam generator body 1. A splash guard 13 is fixedly installed inside the water-air separation cavity 12.
[0030] The first baffle separator 16 is fixedly installed inside the water-gas separation chamber 12 for guiding and separating steam. The exterior of the first baffle separator 16 is provided with flue gas holes 17. The second baffle separator 18 is fixedly installed above the first baffle separator 16. The fixing frame 19 is fixedly installed above the water-gas separation chamber 12. The inside of the fixing frame 19 is fixedly installed with a gradient flue pipe 20. When the steam rises, it encounters the first baffle separator 16 and the second baffle separator 18, causing the steam and water molecules to separate again. The steam flows upward through the flue gas holes 17 and then enters the gradient flue pipe 20. Due to the design of the gradient flue pipe 20, which is larger at the bottom and smaller at the top, the steam discharge speed is further accelerated.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, air inlet pipes 7 are fixedly installed on both sides of the back of the preheating combustion chamber 2. An igniter 8 is fixedly installed inside the preheating combustion chamber 2. The igniter 8 is used to ignite the internal combustion gas of the preheating combustion chamber 2 to heat the preheating main chamber pipe 4 and achieve rapid preheating of the internal water flow. The other end of the water supply pipe 11 is fixedly connected to the water-gas separation chamber 12. The splash plate 13 is set with an L-shaped structure. When the preheated water flows into the water-gas separation chamber 12 from the water supply pipe 11, it is first blocked by the splash plate 13, so that the heated water and vapor are separated.
[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a partition plate 14 is fixedly installed inside the water-gas separation chamber 12. An electric heating tube 15 is fixedly installed below each partition plate 14. The electric heating tube 15 is used to reheat the preheated water flow at the bottom of the water-gas separation chamber 12, so that the water-gas separation is more thorough. The number of flue gas holes 17 is set to multiple, and the multiple flue gas holes 17 are evenly distributed on the first baffle separator 16. When the steam rises, it encounters the first baffle separator 16 and the second baffle separator 18, so that the steam and water molecules are separated again. A return pipe 21 is fixedly installed at the top of the gradient flue pipe 20, and a flue gas outlet pipe 22 is fixedly installed at the top of the return pipe 21. The flue gas outlet pipe 22 is used to discharge the converging steam, thereby completing the operation of the steam generator.
[0033] The working principle of this utility model is as follows: First, connect the external power supply and connect the external water pipe to the inlet pipe 5, allowing the external water to flow into the preheating combustion chamber 2 through the inlet pipe 5. Then, allow the gas to enter the preheating combustion chamber 2 through the gas inlet pipe 7. At this time, the gas inside can be ignited by the igniter 8, thereby causing combustion and heating inside the preheating combustion chamber 2, which conducts heat to the water flow in the preheating main chamber pipe 4. Then, after the external water flows into the preheating main chamber pipe 4 through the inlet pipe 5, it is guided by the spiral guide plate 9 inside the preheating main chamber pipe 4, causing the water flow to move in a spiral turbine shape inside the preheating main chamber pipe 4. In this way, when the preheating combustion chamber 2 preheats the preheating main chamber pipe 4, the residence time of the water flow can be increased. The preheated water then flows out from the transparent display chamber 10 and the water supply pipe 11, and then flows into the water-gas separation chamber 12. It is first blocked by the splash plate 13, causing the heated water and vapor to separate. Then, the switch of the electric heating tube 15 at the bottom of the water-gas separation chamber 12 is turned on, allowing the electric heating tube 15 to reheat the preheated water flow, making the water-gas separation more thorough. Subsequently, when the steam rises, it encounters the first baffle separator 16 and the second baffle separator 18, causing the steam to... The steam and water molecules separate again, and the steam flows upward through the flue gas hole 17, then enters the gradient flue pipe 20. Due to the design of the gradient flue pipe 20, which is wider at the bottom and narrower at the top, the steam discharge speed is further accelerated. This gives the steam generator a flow guiding structure. This flow guiding structure design allows the water flow to absorb the heat generated in the combustion chamber more fully, thereby improving thermal efficiency. Then, the splash plate 13 performs preliminary separation of the heated water vapor, while the first baffle separator 16 and the second baffle separator 18 further separate the steam and water molecules. This multi-stage separation design ensures that the output steam has a higher dryness, meeting the requirements of... The high-quality steam requirement is met, and the design of the gradient flue 20, which is wider at the bottom and narrower at the top, utilizes the Venturi effect to accelerate the steam discharge speed. This not only improves the response speed of the steam generator but also makes the steam discharge smoother, thus improving the overall efficiency. Afterward, the heated water is discharged through the external pipe of the steam generator body 1, thus completing the use of the steam generator. Finally, after completing all the installation and use of the steam generator according to the above operations, turn off the igniter 8 switch. If it is not used for a long time, simply disconnect the external power supply. In this way, the use process of the steam generator with the flow guiding structure is completed.
[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
