Description

Technical Field

[0001] This invention relates to the field of thermal energy engineering technology, and in particular to a layered independent heating chamber electrode-type steam boiler. Background Technology

[0002] Electrode-type steam boilers are widely used in industrial heating and building heating due to their high thermal efficiency and convenient control. In today's diverse heating scenarios, users have significantly different requirements for hot water temperature; for example, industrial processes require high-temperature water, while daily heating requires medium-temperature water. This places clear demands on the boiler's multi-temperature zone output capability.

[0003] Existing equipment mostly uses a single-chamber heat exchange structure, which can only output hot water at a single temperature. To meet multiple temperature requirements, multiple boilers need to be connected in parallel, which increases equipment costs and floor space, and complicates control. Some improved equipment uses baffles to divide the chambers, but insufficient sealing leads to water convection mixing and temperature interference, making precise independent temperature control impossible.

[0004] Meanwhile, the single-cavity structure is prone to slow water flow and uneven contact between cold water and heat exchange tubes, leading to localized overheating and large overall temperature differences. Furthermore, during steam heat exchange, heat is released gradually from top to bottom, and the thermal energy in the upper high-temperature section and the lower low-temperature section is not utilized in a graded manner, resulting in energy waste and failing to meet energy conservation requirements.

[0005] In summary, existing boilers suffer from problems such as lack of multi-temperature output, susceptibility to temperature fluctuations in the chambers, and inefficient heat utilization, making them unsuitable for diverse needs. Therefore, developing a layered heating structure with independent temperature control and simultaneous multi-temperature output is crucial for improving boiler adaptability and energy efficiency. Summary of the Invention

[0006] In order to overcome the shortcomings of existing electrode steam boilers, which are mostly single-cavity structures, cannot achieve independent output of multiple temperature zones, are prone to temperature coupling interference, and have low thermal energy utilization, this invention provides a layered independent heating cavity electrode steam boiler.

[0007] Technical Solution: A layered independent heating chamber electrode-type steam boiler includes a heating frame, a control panel, horizontal partitions, vertical partitions, heat exchange tubes, connecting pipes, steam pipes, liquid pipes, water outlet pipes, and a temperature sensor. The control panel is fixed to the front wall of the heating frame. Inside the heating frame, one horizontal partition and two vertical partitions are connected, dividing the interior of the heating frame into four independent heating chambers. Each of the four heating chambers has a fixedly installed heat exchange tube. The heat exchange tubes adopt a continuous serpentine bending structure design, with the lower end of the upper heat exchange tube connected to the lower... The upper ends of the heat exchange tubes are sealed and connected by a connecting pipe. The upper ends of the two heat exchange tubes in the upper layer extend out from the right side wall of the heating frame, and the exit ends are connected to steam pipes. Liquid pipes are connected through the right side wall of the heating frame at the position corresponding to each heating chamber. Water outlet pipes are connected through the two side walls of the heating frame at the position corresponding to each heating chamber. The lower ends of the two heat exchange tubes in the lower layer extend out from the right side wall of the heating frame. Temperature sensors are embedded in the heating frame near each water outlet pipe. The temperature sensors are electrically connected to the control panel through wires.

[0008] In addition, it is particularly preferred that the heat exchange tube is made of TA2 titanium alloy and that the inner wall of the heat exchange tube is integrally formed with spiral ridges.

[0009] In addition, it is particularly preferred that the outer wall of the heating frame is covered with a rock wool insulation layer.

[0010] In addition, it is particularly preferred that the heating frame also includes guide plates, with two obliquely arranged guide plates connected at intervals above each of the four heating chambers.

[0011] Furthermore, it is particularly preferred that the upper and lower end faces of the guide plate are provided with a hydrophobic coating.

[0012] Furthermore, particularly preferably, it also includes a rotating shaft, impeller, geared disc, planetary gears, sun gear, conveyor wheel, and conveyor belt. A rotating shaft is rotatably connected inside each steam pipe, and an impeller is connected to each rotating shaft. The impellers are located inside the steam pipe cavity. A geared disc is rotatably connected to the rear wall of each steam pipe. An isolation chamber is provided inside the rear side of the steam pipe. The rear end of the rotating shaft rotatably passes through the isolation chamber and is connected to the sun gear. Three planetary gears are rotatably connected at intervals inside the geared disc. The inner ends of the three planetary gears mesh with the corresponding sun gears, and the outer ends of the three planetary gears mesh with the teeth inside the geared disc. A main shaft is located at the center of the rear side wall of the toothed disc. This main shaft rotates and passes through the corresponding liquid pipe behind it. An impeller is also coaxially connected to the section of the toothed disc main shaft located in the inner cavity of the liquid pipe. The toothed disc main shaft continues to rotate and passes through the rear side wall of the liquid outlet pipe. A conveyor wheel is connected at this position. Impellers are also rotatably connected to the liquid pipes of the heating frame that act on the two heating chambers below through rotating shafts. The rotating shafts on the impellers rotate through the outside of the liquid outlet pipe and are also fixedly connected to the conveyor wheel at this position. A synchronous conveyor belt is wound between the upper and lower conveyor wheels on the same vertical line.

[0013] Furthermore, preferably, it also includes a worm, a conveyor wheel, axle, worm gear, wheel rod, stirring wheel, and flat belt. Support seats are symmetrically installed on the right side wall of the heating frame corresponding to the horizontal partition. A worm is rotatably connected to each support seat. A conveyor wheel is connected to the inner end of each worm. The conveyor wheel has a grooved wheel structure. The conveyor belt is embedded in the groove of the conveyor wheel to form a sliding fit. Axle is rotatably connected to the right side of each support seat. A worm gear is connected to the upper end of each axle. The worm gear meshes with the worm on the corresponding side. Multiple wheel rods are rotatably connected at intervals on both sides of the horizontal partition. The upper and lower ends of the wheel rods penetrate the upper and lower surfaces of the horizontal partition and extend into the upper and lower heating chambers. A stirring wheel is connected to the extension end of each wheel rod inside the heating chamber. A flat belt is wound between two horizontally adjacent wheel rods. A flat belt is also wound between the rightmost wheel rod and the axle on the same side.

[0014] Furthermore, it is particularly preferred that the blades of the stirring wheel have an arc-shaped bent structure.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The heating frame is divided into four independent heating chambers by horizontal and vertical partitions. Combined with the independent inlet and outlet water pipes and temperature sensors of each chamber, it is possible to realize the zoned output and precise monitoring of hot water at different temperatures. Users can obtain high-temperature hot water and medium-temperature heat preservation water according to different needs such as heating and process, which improves the application flexibility and energy efficiency of the equipment.

[0016] 2. Steam flows from top to bottom in the serpentine heat exchange tube, releasing its heat step by step. The upper heating chamber uses high-temperature steam to heat the cold water to the target temperature, while the lower heating chamber uses waste heat to preheat or keep the water warm, thus completing the staged utilization of steam thermal energy. This process effectively reduces the heat loss of discharged condensate and improves the overall energy utilization rate.

[0017] 3. The staggered guide plate installed in the heating chamber can guide the cold water to flow in a step-like and uniform manner, avoiding short circuits and dead zones. At the same time, the stirring wheel driven by the steam flow disturbs the water, further enhancing the heat exchange between the water and the heat exchange tube wall. The combination of the two ensures uniform heating and effectively improves the heat exchange efficiency.

[0018] 4. This device uses the kinetic energy of steam flow to drive the impeller, and transmits the power to the liquid pipe impeller and stirring system through gear set and belt. When the steam flow rate increases, the cold water injection speed and stirring intensity increase simultaneously, realizing automatic matching and dynamic balance between steam supply and water supply. No external power is required, making the operation more intelligent and reliable. Attached Figure Description

[0034] Example 1: A layered independent heating chamber electrode-type steam boiler, such as Figures 1-5As shown, the device includes a heating frame 1, a guide plate 2, a control panel 101, a horizontal partition 102, a vertical partition 103, a heat exchange tube 104, a connecting pipe 105, a steam pipe 106, a liquid pipe 107, a water outlet pipe 108, and a temperature sensor 109. The heating frame 1 has a hollow cavity structure. The control panel 101 is fixed to the lower right side of the front wall of the heating frame 1 using an embedded installation method. A horizontal partition 102 is connected horizontally in the middle of the heating frame 1 by screws. The horizontal partition 102 divides the interior of the heating frame 1 into an independent upper chamber and a lower chamber, forming an upper and lower heating base. Vertical partitions 103 are connected vertically in the middle of the upper and lower chambers of the heating frame 1 by screws. The ends of the vertical partitions 103 and the horizontal partitions 102 are connected... The heating frame 1 is fixedly connected to the surface. Through a cross-shaped partition structure of vertical partition 103 and horizontal partition 102, the upper chamber is further divided into an upper front heating chamber and an upper rear heating chamber, and the lower chamber is divided into a lower front heating chamber and a lower rear heating chamber. This results in four independent heating chambers within the heating frame 1, providing structural support for independent layered heating. Each of the four heating chambers has a vertically fixed heat exchange tube 104. The heat exchange tube 104 adopts a continuous serpentine bending structure design, which maximizes the contact area between the heat exchange tube 104 and the liquid, improving heat exchange efficiency. The left and right bends of the heat exchange tube 104 penetrate the left and right sidewalls of the heating frame 1 and are sealed and fixed to the heating frame 1, ensuring the airtightness of the heating chamber. The heat exchange tube 104 is made of TA2 titanium alloy. Made of titanium alloy, it exhibits excellent corrosion resistance and high-temperature resistance, making it suitable for steam heat exchange conditions. The inner wall of the heat exchange tube 104 is integrally formed with spiral ridges, which can disturb the steam flow inside the tube, improving heat transfer efficiency. On the same vertical line, the lower end of the upper heat exchange tube 104 and the upper end of the lower heat exchange tube 104 are sealed and connected by a connecting pipe 105. The upper ends of the two upper heat exchange tubes 104 both extend from the right side wall of the heating frame 1, and the extending ends are sealed and connected to a steam pipe 106. The steam pipe 106 serves as a dedicated channel for steam input, used to connect to the high-temperature steam generated by the electrode boiler. A liquid pipe 107 runs through and is sealed and connected to each heating chamber on the right side wall of the heating frame 1. The liquid pipe 107 serves as the input channel for the liquid to be exchanged. The installation position is located in the upper part of the heating chamber. This design allows the liquid to be heat-exchanged to flow evenly from top to bottom along the inner wall of the heating chamber under the action of gravity, ensuring full contact with the heat exchange tube 104. Water outlet pipes 108 are installed through and sealed on both the front and rear side walls of the heating frame 1, corresponding to the position of each heating chamber. The water outlet pipes 108 are installed in the lower part of the heating chamber to facilitate the complete output of the liquid after heat exchange in each chamber. The lower ends of the two lower heat exchange tubes 104 extend through the right side wall of the heating frame 1 to the outside, serving as discharge channels for excess steam and condensate, for docking with external recovery equipment to achieve energy recovery. Temperature sensors 109 are embedded with screws near each water outlet pipe 108 on the heating frame 1, with the sensing end of the temperature sensor 109 extending into the heating chamber.Temperature sensors 109 and control panels 101 are electrically connected via wires to collect real-time temperature data of the liquid in each heating chamber, enabling real-time transmission and display of temperature data. The outer wall of the heating frame 1 is covered with a rock wool insulation layer, effectively reducing heat loss from the heating frame 1 to the surrounding environment. This improves the energy efficiency of the equipment, achieving energy-saving operation, and also reduces the surface temperature of the equipment, improving operator safety and the working environment. Two obliquely arranged guide plates 2 are fixedly connected above each of the four heating chambers of the heating frame 1. The two guide plates 2 in each heating chamber are spaced apart vertically and staggered left and right, forming a stepped flow channel to guide the liquid to flow orderly along the surface of the heat exchange tube 104. The upper and lower surfaces of the guide plates 2 are coated with a hydrophobic coating made of polytetrafluoroethylene (PTFE) to prevent liquid from accumulating on the plate surface and ensure uniform liquid flow through the heat exchange tube 104.

[0035] When this device is put into use, firstly, the steam output end of the external electrode boiler is connected to the two steam pipes 106 of this device through a sealed pipe. The output end of the cold water supply system is connected to the four liquid pipes 107 through branch pipes. The hot water usage ends (such as heating systems, process water pipelines, domestic water pipelines, etc.) are connected to the four outlet pipes 108 through pipes. The steam recovery equipment is connected to the lower ports of the two lower heat exchange tubes 104 through pipes to form a closed-loop recovery system. After the device is started, the external electrode boiler converts electrical energy into steam heat energy. The high-temperature steam is transported to the steam pipes 106 through pipes, and then diverted into the two upper heat exchange tubes 104. The steam in the upper heat exchange tubes 104 releases heat during the heat exchange process, and part of it condenses into high-temperature condensate. The uncondensed steam and condensate flow into the corresponding lower heat exchange tubes 104 through the connecting pipe 105 to continue participating in the heat exchange process. At the same time, cold water is injected into the four heating pipes 107 through the liquid pipes 107. In the hot chamber, under the combined action of gravity and the guide plate 2, cold water forms a stepped flow path along the left and right staggered guide plates 2, flowing evenly from top to bottom across the surface of the heat exchange tube 104, fully absorbing the heat released by the steam. The temperature sensor 109 collects the temperature data of the liquid in each heating chamber in real time and transmits the data to the control panel 101. The control panel 101 displays the temperature of each chamber independently. Since the steam flows from top to bottom in the heat exchange tube 104, the heat is gradually released. The cold water in the upper heating chamber can be heated to a preset high temperature, while the cold water in the lower heating chamber is heated to a medium temperature and continuously kept warm, meeting the hot water temperature requirements of different scenarios. The hot water in each heating chamber that has reached the preset temperature is output to the user end through the corresponding outlet pipe 108. The excess steam and condensate formed in the lower heat exchange tube 104 are transported to the recovery equipment through the lower port. The recovered condensate can be transported back to the feedwater system of the electrode boiler to achieve energy recycling.

[0036] Example 2: Based on Example 1, such as Figures 6-14 As shown, it also includes a rotating shaft 301, an impeller 302, a geared disc 303, planetary gears 304, a sun gear 305, a conveyor wheel 306, and a conveyor belt 307. The rotating shaft 301 is rotatably connected inside the steam pipe 106, and an impeller 302 is keyed to each rotating shaft 301. The impeller 302 is located inside the steam pipe 106. A geared disc 303 is rotatably connected to the rear wall of the steam pipe 106. An isolation chamber is provided inside the rear side of the steam pipe 106, which communicates with the interior of the geared disc 303. The rear end of the rotating shaft 301 rotatably penetrates into the isolation chamber and is keyed to a sun gear 305. Three planetary gears 304 are rotatably connected to the geared disc 303 along circumferentially spaced bearings. The inner ends of the three planetary gears 304 mesh with the corresponding sun gear 305, and the outer ends of the three planetary gears 304 mesh with the inner teeth of the geared disc 303, forming a speed reduction structure. The planetary gears 304 and the sun gear 305 are housed in the isolation chamber. Inside the cavity, a main shaft is located at the center of the rear side wall of the gear disc 303. This main shaft rotates and passes through the corresponding liquid pipe 107 behind it. The section of the gear disc 303 main shaft located in the inner cavity of the liquid pipe 107 is also coaxially keyed to an impeller 302. The gear disc 303 main shaft continues to rotate and passes through the rear side wall of the liquid pipe 107, where a conveyor wheel 306 is fixedly connected. The liquid pipes 107 on the heating frame 1 that act on the two heating chambers below are also rotatably connected to impellers 302 through rotating shafts 301. The rotating shafts 301 on the impellers 302 rotate and pass through the outside of the liquid pipe 107, where a conveyor wheel 306 is also keyed. A synchronous conveyor belt 307 is wound between the upper and lower conveyor wheels 306 on the same vertical line to achieve synchronous linkage between the impellers 302 of the upper and lower liquid pipes 107, ensuring coordinated adjustment of the cold water input speed of the upper and lower liquid pipes 107.

[0037] When steam generated by the external electrode boiler is transported to steam pipe 106 through the pipeline, the high-speed steam flow impacts the impeller 302 inside the steam pipe 106, causing the impeller 302 to rotate around the shaft 301. The shaft 301 drives the sun gear 305 at its end to rotate synchronously, completing the conversion of steam kinetic energy into mechanical kinetic energy. The sun gear 305 drives three planet gears 304 to rotate synchronously. Since the planet gears 304 mesh with the internal gear ring of the gear disk 303 at the same time, while rotating around their own axis, the planet gears 304 also revolve around the sun gear 305, thereby driving the gear disk 303 to rotate at a lower speed than the sun gear 305, achieving deceleration and torque increase. The gear disk 303 drives the main shaft at its center to rotate synchronously. The main shaft transmits power to the impeller 302 inside the upper liquid pipe 107. The impeller 302 inside the upper liquid pipe 107 rotates under the drive of the main shaft, pushing the cold water inside the liquid pipe 107 through its blades, accelerating the cold water transport. Simultaneously, the conveyor wheel 306 at the end of the upper liquid pipe 107 shaft 301 drives the shaft 301 and impeller 302 in the lower liquid pipe 107 to rotate via the conveyor belt 307, realizing synchronous adjustment of the cold water input speed of the lower liquid pipe 107. This mechanism forms a closed-loop regulation link of "steam quantity - impeller 302 speed - cold water quantity". When the output steam quantity of the electrode boiler increases, the steam flow velocity in the steam pipe 106 increases, and the impeller 302 speed increases. After being transmitted through the deceleration structure, the impeller 302 speed in the liquid pipe 107 increases synchronously, and the cold water input quantity increases accordingly, ensuring the balance of heat exchange ratio between liquid and steam in the heating chamber. When the steam quantity decreases, the steam flow velocity decreases, the impeller 302 speed decreases, and the cold water input quantity decreases accordingly, avoiding excessively high temperature of liquid in the heating chamber due to excessive steam or excessively low temperature due to insufficient steam, thus realizing dynamic matching of steam supply and cold water input quantity.

[0038] like Figures 6-9As shown, it also includes a worm gear 401, a conveyor wheel 402, axle 403, worm gear 404, wheel rod 405, stirring wheel 406, and a flat belt 407. Support seats are symmetrically installed on the right side wall of the heating frame 1, corresponding to the position of the horizontal partition 102, via bolts. A worm gear 401 is rotatably connected to each support seat. A conveyor wheel 402 is keyed to the inner end of each worm gear 401. The conveyor wheel 402 has a grooved wheel structure. The conveyor belt 307 is embedded in the groove of the conveyor wheel 402 to form a sliding fit, ensuring that the conveyor belt 307 can synchronously drive the conveyor wheel 402 to rotate when it rotates. The conveyor wheel 402, together with the upper and lower conveyor wheels 306 on the same vertical line, forms a triangular power transmission node, ensuring that the conveyor belt 307 is taut and that power transmission is without deviation. Axle 403 is rotatably connected to the right side of each support seat. A worm gear 404 is fixedly connected to the upper end of each axle 403. The worm gear 404 meshes with the worm gear 401 on the corresponding side. The horizontal partition 102... The heating frame 1 has an internal cavity, and a through hole is provided on the right side wall of the heating frame 1 corresponding to the cavity. Multiple wheel rods 405 are rotatably connected to the front and rear sides of the horizontal partition 102 at intervals. The upper and lower ends of the wheel rods 405 pass through the upper and lower surfaces of the horizontal partition 102 and extend into the upper and lower heating cavities. A stirring wheel 406 is fixedly connected to the extension end of the wheel rod 405 inside the heating cavity. The blades of the stirring wheel 406 have an arc-shaped bending structure, which makes the liquid turbulence more uniform during stirring. In the cavity of the horizontal partition 102, a flat belt 407 is wound between two horizontally adjacent wheel rods 405. The rightmost wheel rod 405 on both the front and rear sides is also wound with a flat belt 407 between it and the wheel axle 403 on the same side. The flat belt 407 passes through the through hole in the side wall of the heating frame 1, and all the flat belts 407 are housed in the cavity of the horizontal partition 102 to achieve physical isolation from the liquid in the heating cavity and avoid liquid corrosion that could cause transmission failure.

[0039] When the conveyor belt 307 rotates to transmit power, it synchronously drives the conveyor wheel 402 to rotate. The conveyor wheel 402 drives the worm gear 401 to rotate, and the worm gear 401 drives the worm wheel 404 and the wheel shaft 403 to rotate. The wheel shaft 403 drives the adjacent wheel rod 405 to rotate through the flat belt 407. All the wheel rods 405 rotate synchronously through the transmission of the flat belt 407. When the wheel rod 405 rotates, the stirring wheel 406 at its upper and lower ends rotates synchronously. The stirring wheel 406 generates radial thrust on the liquid in the heating chamber, breaking the natural settling flow state of the liquid and causing the liquid to form in the heating chamber. The circulating flow promotes full contact between the cold water and the surface of the heat exchange tube 104, while eliminating temperature dead zones in the heating chamber, ensuring uniform liquid temperature and improving overall heat exchange efficiency. The rotational speed of the stirring wheel 406 is positively correlated with the steam volume. When the steam volume increases, the conveyor belt 307 speeds up, and the stirring wheel 406 speed increases synchronously, increasing the stirring intensity to match the increased cold water input and steam heat. When the steam volume decreases, the stirring wheel 406 speed decreases to avoid energy waste caused by excessive stirring, achieving dynamic coordination between stirring intensity and heat exchange requirements.
