Description

Technical Field

[0001] The present invention relates to the technical field of steam boilers, and specifically, to an energy-saving steam boiler. Background Art

[0002] A steam boiler is a thermal energy device widely used in industrial production. Its main function is to heat water to boiling by the heat generated from burning fuels (such as coal, oil, natural gas, biomass, etc.) to generate steam. The steam is then transported to various industrial processes for multiple purposes such as heating, drying, distillation, power generation, etc. Under the framework of traditional technology, the operation mechanism of the steam boiler has certain limitations. Specifically, the entire body of water in the container needs to be fully heated to the boiling point until the internal pressure accumulates to a predetermined threshold to effectively release the steam. After this process, the system needs to refill cold water and start the heating cycle again. This repeated process of heating water to boiling not only consumes a large amount of fuel resources, but also the combustion efficiency of the fuel does not reach an ideal state, resulting in unnecessary waste of energy and potential threats to the environmental air quality.

[0040] Referring to Figures 1 to 6 , an embodiment of the present invention provides an energy-saving steam boiler, which includes an outer shell 1, an inner shell 2, and a partition shell 3. The inner shell 2 and the partition shell 3 are both arranged inside the outer shell 1. A first heating water chamber 101 is formed between the inner wall of the outer shell 1, the outer wall of the inner shell 2, and the outer wall of the partition shell 3. The first heating water chamber 101 has a water inlet 102, an external steam outlet 104, and a smoke outlet 103. The inside of the inner shell 2 has a heat source chamber 201. The partition shell 3 is arranged on the outer wall of the inner shell 2. A second heating water chamber 301 is formed between the partition shell 3 and the inner shell 2. The second heating water chamber 301 is communicated with the first heating water chamber 101. A waste heat coil 4 is located in the second heating water chamber 301. One end of the waste heat coil 4 is communicated with the heat source chamber 201, and the other end leads to the smoke outlet 103.

[0041] In this embodiment, a design scheme of an energy-saving steam boiler is involved. This design aims to improve energy utilization efficiency and reduce environmental pollution. The specific structure and operating principle are as follows. The outer shell 1 is made of high-strength heat-resistant material, providing structural support and protection for the entire steam boiler. The inner shell 2 is placed inside the outer shell 1 to form a heat source chamber 201. A first heating water chamber 101 is formed between the inner shell 2 and the outer shell 1. This space is used for initially heating the water body to make a preliminary heating. The partition shell 3 is installed on the outer wall of the inner shell 2 and together with the inner shell 2 forms a second heating water chamber 301. This space is used to further raise the critical water temperature to the boiling state to generate steam. The first heating water chamber 101: is surrounded by the inner wall of the outer shell 1, the outer wall of the inner shell 2, and the outer wall of the partition shell 3. It has a water inlet 102 for introducing cold water, an outlet steam port 104 for discharging the generated steam, and a smoke outlet 103 for discharging the flue gas. The second heating water chamber 301 is located between the inner shell 2 and the partition shell 3. Through heat exchange with the heat source chamber 201, the temperature of the water body rises rapidly to reach the steam generation condition. The waste heat coil 4 is arranged in the second heating water chamber 301, with one end connected to the heat source chamber 201 and the other end leading to the smoke outlet 103. Its function is to recover the waste heat in the flue gas and preheat the water body entering the heat source chamber 201, thereby improving the overall thermal efficiency. At the same time, the position of the partition shell 3 is at a position far from the fuel inlet. The temperature of the heat source chamber 201 at this position is relatively low and the flue gas concentration is the highest. Using a relatively low heat source temperature and a high flue gas concentration to heat a small amount of water at the critical water temperature can achieve a higher heating efficiency and maximize the utilization of the thermal energy distribution of the device.

[0042] Furthermore, both the outer shell 1 and the inner shell 2 are cylindrical. One side of the second heating water chamber 301 has a water outlet hole 302. It also includes a baffle 5. The baffle 5 is rotatably arranged on the outer wall of the inner shell 2, and the baffle 5 has a blocking part 501. After the baffle 5 rotates, the blocking part 501 blocks or cancels blocking the water outlet hole 302, enabling the second heating water chamber 301 to communicate with the first heating water chamber 101.

[0043] In this embodiment, the newly added baffle 5 is designed as a rotatable structure and is installed on the outer wall of the inner housing 2, specifically on one side of the second heating water chamber 301. There is a blocking portion 501 on the baffle 5. When the baffle 5 is in a specific position, the blocking portion 501 can block or release the water outlet hole 302 on the second heating water chamber 301, thereby controlling the on-off of the water flow between the two heating water chambers. By rotating the baffle 5, the connection between the second heating water chamber 301 and the first heating water chamber 101 can be selectively opened or closed. In the initial stage, the baffle 5 is in a closed state, and the water body in the first heating water chamber 101 is only heated and raised in temperature through primary heating; when the water temperature reaches a certain threshold, the operator can rotate the baffle 5 manually or through an automatic control system, so that the blocking portion 501 moves away from the water outlet hole 302, allowing the preheated water body to flow into the second heating water chamber 301 for secondary heating until steam is generated. The addition of the baffle 5 enables the steam boiler to flexibly adjust the water circulation path under different working conditions. For example, under low load requirements, the baffle 5 can be closed to reduce the use of the second heating water chamber 301 and save energy; under high load requirements, the baffle 5 is opened to make full use of all the heating chambers 303 to increase the steam output.

[0044] Furthermore, there are several water outlet holes 302, which are arranged around the circumference of the inner housing 2, and the baffle 5 is annular.

[0045] In this embodiment, the water outlet hole 302 is no longer limited to a single position, but is designed as multiple ones, evenly distributed around the circumference of the inner housing 2. Such a layout ensures the uniform heating of the water body in the second heating water chamber 301 and avoids problems such as local overheating or uneven heating. The baffle 5 is designed as an annular shape, matching the circumferential shape of the inner housing 2, ensuring the complete covering or releasing of the multiple water outlet holes 302. When the blocking portion 501 no longer blocks the water outlet hole 302 and the baffle 5 rotates to a specific position, the connection between the second heating water chamber 301 and the first heating water chamber 101 is achieved.

[0046] Furthermore, it further includes a partition plate 6 slidably arranged in the second heating water chamber 301, the sliding direction is along the axial direction of the inner housing 2, and the partition plate 6 divides the second heating water chamber 301 into a heating chamber 303 and a steam outlet chamber 304. The partition plate 6 has a communication port 601, and the communication port 601 is used to connect the heating chamber 303 to the steam outlet chamber 304, and a steam outlet pipe 7, one end of the steam outlet pipe 7 is connected to the steam outlet chamber 304, and the other end leads to the external steam outlet 104.

[0047] In this embodiment, the partition plate 6 can slide axially along the inner housing 2 inside the second heated water chamber 301, which means that the position of the partition plate 6 can be adjusted by a mechanical or electric device to change the volume ratio of the heating chamber 303 and the steam outlet chamber 304. Through the dynamic adjustment of the partition plate 6, the amount of water entering the heating chamber 303 and the steam accumulation amount in the steam outlet chamber 304 can be controlled in real time, thereby achieving fine control of the steam generation speed and pressure. The communication port 601 on the partition plate 6 ensures that the water vapor in the heating chamber 303 can smoothly transition to the steam outlet chamber 304, while preventing water bodies from directly flowing into the steam outlet chamber 304, effectively avoiding the "water-carrying" phenomenon and improving the steam quality. One end of the steam outlet pipe 7 is tightly connected to the steam outlet chamber 304, and the other end is directly directed to the external steam outlet 104 of the boiler, ensuring the smooth discharge of steam, reducing the residence time of steam in the chamber, and thus improving the purity and temperature of the steam. The reasonable design and use of the partition plate 6 contribute to maintaining a stable steam pressure, reducing the risk of overpressure, and increasing the safety and reliability of the equipment.

[0048] Furthermore, a one-way pressure limiting valve 8 is provided in the communication port 601 for allowing the gas in the heating chamber 303 to enter the steam outlet chamber 304. The first elastic member 9 is located in the steam outlet chamber 304, with one end provided on the inner wall of the steam outlet chamber 304 and the other end provided on the partition plate 6, providing a force for the partition plate 6 to move away from the inner wall of the steam outlet chamber 304.

[0049] In this embodiment, the one-way pressure limiting valve 8 is installed in the communication port 601 of the partition plate 6 to control the steam flow from the heating chamber 303 to the steam outlet chamber 304. When the steam pressure in the heating chamber 303 reaches the preset threshold, the one-way pressure limiting valve 8 automatically opens, allowing the excess steam to smoothly enter the steam outlet chamber 304, preventing the internal pressure of the heating chamber 303 from being too high. At the same time, it ensures that the steam can only flow from the heating chamber 303 to the steam outlet chamber 304 and will not flow back, thus avoiding the influence of the steam pressure in the steam outlet chamber 304 on the normal operation of the heating chamber 303 and maintaining the stable operation of the system. The first elastic member 9 is located in the steam outlet chamber 304, with one end fixed on the inner wall of the steam outlet chamber 304 and the other end connected to the partition plate 6, providing a force for the partition plate 6 to move away from the inner wall of the steam outlet chamber 304. This means that when the steam pressure in the heating chamber 303 is low, the first elastic member 9 will push the partition plate 6 to reduce the communication area between the heating chamber 303 and the steam outlet chamber 304. Conversely, when the steam pressure increases, the partition plate 6 is pushed back by the steam pressure to increase the communication area, achieving the purpose of automatically adjusting the steam flow rate. Through the elastic force of the first elastic member 9, the pressure balance between the heating chamber 303 and the steam outlet chamber 304 can be automatically adjusted, avoiding equipment failures or energy waste caused by excessive pressure differences.

[0050] Further, one end of the steam outlet pipe 7 located in the steam outlet cavity 304 has a conical opening 701. A conical stopper 10 is also slidably disposed within the conical opening 701, and the sliding direction is along the axial direction of the steam outlet pipe 7. The conical stopper 10 has an upper conical surface 1001, and an air flow channel 1002 is formed between the upper conical surface 1001 and the inner wall of the conical opening 701. After the conical stopper 10 slides, the air flow channel 1002 expands or contracts.

[0051] In this embodiment, the conical stopper 10 can slide along the axial direction of the steam outlet pipe 7, and the size of the air flow channel 1002 formed between its upper conical surface 1001 and the inner wall of the conical opening 701 will change with the position of the stopper. When the stopper moves upward, the air flow channel 1002 contracts, restricting the outflow of steam; conversely, when the stopper moves downward, the air flow channel 1002 expands, increasing the steam flow capacity. This dynamic adjustment mechanism can adjust the steam flow rate in real time according to actual needs to achieve refined management. The sliding of the conical stopper 10 can also help the system adapt to different pressure environments. In high-demand situations, the steam supply can be increased by expanding the air flow channel 1002, while in low-demand or maintenance periods, the steam loss can be reduced by reducing the channel to maintain the system pressure stability. By precisely controlling the steam output, unnecessary steam waste is avoided, energy consumption is reduced, and the energy efficiency ratio of the entire system is improved. At the same time, the heat loss caused by uneven steam discharge is reduced, further enhancing the energy-saving effect. Also, when the air pressure in the steam outlet cavity 304 fluctuates, the stability of the air flow velocity can be achieved through this design.

[0052] Further, the conical stopper 10 also has a lower conical surface 1003. A pusher 11 is also disposed on the partition plate 6 and located within the steam outlet cavity 304. One end of the pusher 11 has a pushing portion 1101. After the partition plate 6 drives the pusher 11 to slide, the pushing portion 1101 slidably abuts against the lower conical surface 1003 to drive the conical stopper 10 to slide. One end of the second elastic member 12 is disposed on the inner wall of the conical opening 701, and the other end is disposed on one end of the conical stopper 10, providing a force for the conical stopper 10 to slide away from the inner wall of the conical opening 701.

[0053] In this embodiment, a linkage mechanism of the pushing member 11 and the second elastic member 12 is introduced, further optimizing the automation level of steam flow control and enhancing the overall responsiveness and energy efficiency of the system. The pushing member 11 is fixed on the partition plate 6 and is located inside the steam outlet cavity 304. When the partition plate 6 moves due to the change in steam pressure in the heating cavity 303, the pushing member 11 acts accordingly. The pushing portion 1101 at one end of the pushing member 11 comes into contact with the lower conical surface 1003 of the conical stopper 10, thereby driving the conical stopper 10 to slide axially along the steam outlet pipe 7. This linkage mechanism enables the adjustment process of the steam flow to be automated without the intervention of additional mechanical or electronic control devices. When the steam pressure in the heating cavity 303 increases, the partition plate 6 is pushed, indirectly causing the conical stopper 10 to slide upward through the pushing member 11, reducing the steam flow channel 1002, and thus automatically reducing the steam flow; conversely, when the pressure decreases, the partition plate 6 moves back, the conical stopper 10 slides downward, expanding the steam flow channel 1002, and increasing the steam output. One end of the second elastic member 12 is fixed to the inner wall of the conical opening 701, and the other end is connected to the conical stopper 10, providing a force for the conical stopper 10 to slide in a direction away from the inner wall of the conical opening 701. This means that when the external driving force, i.e., the pushing member 11, disappears, the second elastic member 12 can automatically reset the conical stopper 10 to its initial state, ensuring the stable operation of the system without external intervention. The second elastic member 12 also plays a buffering role, reducing the impact force that may be generated during the rapid sliding of the conical stopper 10, protecting the equipment from mechanical damage, and extending its service life.

[0054] Furthermore, the inner housing 2 and the outer housing 1 are eccentrically arranged. The axes of the inner housing 2 and the outer housing 1 are parallel, and the axis of the inner housing 2 is located below the axis of the outer housing 1. The communication port 601 is located above one side of the water outlet hole 302.

[0055] In this embodiment, the structural design of the energy-saving steam boiler is further optimized. By eccentrically arranging the inner shell 2 and the outer shell 1, it aims to improve the thermal efficiency and steam quality of the steam boiler. At the same time, the water circulation path is optimized to ensure the stability of the equipment operation and the energy-saving effect. The axis of the heat source chamber 201 of the inner shell 2 is parallel to the axis of the first heating water chamber 101 of the outer shell 1, but the axis of the inner shell 2 is located below the axis of the outer shell 1. Such a design enables the heat generated by the combustion chamber to be transferred to the water in the outer shell 1 more directly and evenly, reducing the heat loss during the transfer process and improving the thermal efficiency. The communication port 601 is located above one side of the water outlet hole 302, which means that during the process of steam flowing from the second heating water chamber 301 to the first heating water chamber 101, the steam path is more direct, reducing the chance of steam contacting the condensed water. Thereby, the purity and temperature of the steam are improved, the phenomenon of steam carrying water is reduced, and the steam quality is enhanced. The eccentric setting also optimizes the water circulation path, making the water flow more smoothly when flowing from the first heating water chamber 101 to the second heating water chamber 301, reducing the resistance of the water during the flow process, accelerating the water circulation speed, and being beneficial to improving the steam generation efficiency.

[0056] Further, the baffle 5 has a spiral guiding groove 502. The partition plate 6 has a sliding part 602, and the sliding part 602 is slidably arranged in the spiral guiding groove 502. After the partition plate 6 slides, the sliding part 602 drives the baffle 5 to rotate.

[0057] In this embodiment, when the partition plate 6 slides, the movement of the sliding part 602 in the spiral guiding groove 502 will cause the rotation of the baffle 5. This is because the shape of the spiral guiding groove 502 determines that the sliding part 602 will generate a rotational torque on the baffle 5 during the movement, enabling the baffle 5 to rotate relative to the partition plate 6. This linkage mechanism enables the position change of the partition plate 6 to be directly converted into the rotation of the baffle 5, thereby realizing the dynamic control of the opening size of the water outlet hole 302.

[0058] Further, it also includes a blowdown port 13, and the blowdown port 13 and the water inlet 102 are respectively located on both sides of the outer shell 1.

[0059] In this embodiment, the blowdown port 13 and the water inlet 102 are designed to be respectively located on both sides of the outer shell 1. This layout ensures the physical separation of the fresh inlet water and the discharged water containing impurities, avoiding the cross-contamination of water quality and helping to maintain the purity of the water quality inside the steam boiler. Separating the blowdown port 13 and the water inlet 102 on both sides not only simplifies the operation process but also facilitates daily maintenance and quick response in case of emergency. The operator can perform the water inlet and blowdown operations on the opposite sides of the equipment simultaneously, improving the work efficiency.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
