Description

Technical Field

[0001] The invention relates to the technical field of steam boilers, and in particular to a load-adjustable electrode steam boiler. Background Art

[0002] Electrode steam boiler is a device that uses electricity as energy, converts electrical energy into thermal energy through electrodes, and heats water to produce steam.

[0003] A Chinese patent document with the announcement number CN221444243U discloses an immersed electrode steam boiler, which includes an outer cylinder, an inner cylinder installed inside the outer cylinder, two high-voltage electrodes arranged inside the inner cylinder, a steam outlet valve installed on the top of the outer cylinder, a circulation pipe connected to the bottom of the outer cylinder, the other end of the circulation pipe enters from the bottom of the outer cylinder and is connected to a riser, and the top of the riser is connected to the inner cylinder. In the immersed electrode steam boiler, since the electrical resistance of water is used for direct heating, there is basically no heat loss.

[0004] However, when the steam boiler is in use with water and electricity, its heating power is constant and the steam boiler is always in high-load operation. However, after the heat energy output by the steam boiler reaches the user's requirements, it is necessary to maintain the temperature for a long time in the later stage and reduce the output of the heat energy of the steam boiler. At this time, it is necessary to frequently rely on the on and off of the switch to achieve this, which reduces the service life of the high-voltage electrode. In addition, the bubbles generated near the high-voltage electrode flow vertically upward along the surface of the high-voltage electrode. Many bubbles continuously pass through the surface of the high-voltage electrode and tend to form a beating diaphragm, which reduces the contact ability of the high-voltage electrode with the boiler water, hinders the migration of current, and also affects the load of the steam boiler, thereby affecting the heating of the high-voltage electrode. Summary of the invention

[0005] The present invention provides a load-adjustable electrode steam boiler, aiming to solve the problem in the related art that the electrode steam boiler cannot directly adjust the load and the bubbles generated near the high-voltage electrode affect the load of the steam boiler.

[0006] The load-adjustable electrode steam boiler of the present invention comprises an outer cylinder and an inner cylinder arranged in the outer cylinder, wherein both the outer cylinder and the inner cylinder are provided with an electrolyte aqueous solution, the inner cylinder has three independent areas interconnected with each other, a drainage port is provided at the bottom of the inner cylinder, and further comprises:

[0007] Three power supply components are installed on the outer cylinder, each of the power supply components has an electrode disk, the three electrode disks are respectively placed in three independent areas, and the edge of each electrode disk is provided with a plurality of electrode rods inserted into the electrolyte aqueous solution, each electrode rod gradually moves away from the inner wall of the independent area from top to bottom, and the contour of the bottom of the electrode rod gradually expands, so that the electrode rod is in the shape of a hockey stick;

[0008] A water supply mechanism is provided on the outer cylinder and is used to transport the electrolyte aqueous solution in the outer cylinder to the inner cylinder. The water supply mechanism has three insulating baffles, which are respectively located directly below the three power supply components;

[0009] The flow control mechanism is arranged on the outer cylinder and is used to control the flow rate of the drain port.

[0010] The beneficial effects of the present invention are as follows: the flow rate of the electrolyte solution flowing out of the drain port can be adjusted by the flow control mechanism, thereby adjusting the liquid level of the electrolyte solution in the inner shell, and controlling the amount of the electrode rod immersed in the electrolyte solution, thereby controlling the amount of the electrode rod participating in the heating work, thereby achieving the function of regulating the load of the steam boiler; since the electrode rod gradually moves away from the inner wall of the independent zone from top to bottom, the resistance of the electrode rod from top to bottom to the inner wall of the independent zone gradually increases, and the current gradually decreases, and the working intensity of the electrode rod from top to bottom also decreases, which is not only conducive to the rapid adjustment of the load, but also more suitable for maintaining the temperature for a long time at low load operation, thereby preventing the service life of the electrode from being affected; in addition, the electrode rod is inclined, and the bubbles generated by the electrode rod can avoid the electrode rod vertically upward, thereby preventing the bubbles from hindering the migration of current, thereby ensuring the heating effect of the electrode.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the present invention, rather than all the embodiments.

[0032] like Figure 1-Figure 15 , which is the first embodiment of the load-adjustable electrode steam boiler of the present invention, mainly includes an outer cylinder 10, an inner cylinder 20 is installed in the outer cylinder 10, and an electrolyte aqueous solution is provided in the outer cylinder 10 and the inner cylinder 20. Three power supply components 30 are installed on the outer cylinder 10 to form three phases. The inner cylinder 20 serves as a neutral electrode. Each power supply component 30 has a plurality of electrode rods 32, and each electrode rod 32 is inserted into the electrolyte aqueous solution in the inner cylinder 20. A water supply mechanism 40 is provided on the outer cylinder 10 for conveying the electrolyte aqueous solution in the outer cylinder 10 to the inner cylinder 20. After the three power supply components 30 are energized, the electrode rods 32, the electrolyte aqueous solution in the inner cylinder 20 and the inner cylinder 20 form a loop to generate current, and the water heats itself as a resistor to generate steam. A flow control mechanism 60 is provided on the inner cylinder 20 for controlling the electrolyte aqueous solution in the inner cylinder 20 to be discharged into the outer cylinder 10.

[0033] like Figure 1-Figure 3The outer cylinder 10 includes an outer shell 11, and the top of the outer shell 11 is fixedly connected with a steam outlet pipe 12 and a protective ring 13. The steam generated in the outer shell 11 can be transported to the external heat exchanger along the steam outlet pipe 12. The power supply component 30 is installed in the protective ring 13 at the top of the outer shell 11 to protect the power supply component 30. Three brackets 14 are welded to the inner wall of the outer shell 11. Each bracket 14 is made of insulating material. In this embodiment, the bracket 14 is made of insulating ceramic. At least three legs 15 are welded to the bottom of the outer shell 11, and all the legs 15 are evenly distributed along the circumferential direction of the outer shell 11 to support the entire outer shell 11 on the ground. An electrolyte aqueous solution is arranged in the outer shell 11, and the liquid level of the electrolyte aqueous solution is lower than the bottom surface of the inner cylinder 20.

[0034] like Figure 2 , Figure 4 and Figure 5 The inner cylinder 20 includes an inner shell 21, and three connecting plates 22 are welded to the outside of the inner shell 21. Each connecting plate 22 is made of an insulating material. In this embodiment, the connecting plates 22 are made of insulating ceramics. The three connecting plates 22 are detachably connected to the three brackets 14 by bolt fasteners. Rubber gaskets are also crimped between the connecting plates 22 and the brackets 14 to facilitate the disassembly and assembly of the inner cylinder 20. A partition 23 is welded to the inner wall of the inner shell 21. A connecting channel 24 is formed between the bottom of the partition 23 and the bottom of the inner wall of the inner shell 21. Three independent areas 25 of the same size and shape are separated from the side wall of the inner shell 21. The bottoms of the three independent areas 25 are interconnected through the connecting channel 24, so that the electrolyte aqueous solution in the three independent areas 25 can be shared with each other to make the liquid level equal. A drain port 26 is provided at the bottom of the inner shell 21 to discharge the electrolyte aqueous solution in the inner cylinder 20 into the outer cylinder 10.

[0035] like Figure 1 , Figure 2 and Figure 6-Figure 12 The three power supply components 30 are connected to the three phase lines of the three-phase alternating current one by one, and the three power supply components 30 are respectively matched with the three independent areas 25. The distance between the power supply components 30 is equal, which can better adapt to the input current and improve the heating efficiency. Each power supply component 30 includes an electrode heating component and two power-on components connected to the electrode heating component. The electrode heating component is connected to the inner cylinder 20 through the electrolyte aqueous solution in the inner cylinder 20 to form an electrical load path. The water heats itself as a resistor to generate steam. The two power-on components on each power supply component 30 are connected to a phase line together to enhance the conductive performance. Each power-on component is fixedly installed on the top of the outer shell 11.

[0036] like Figure 2 and Figure 6-Figure 10Each electrode heating assembly includes a kidney-shaped electrode disk 31, and a plurality of electrode rods 32 are detachably connected to the electrode disk 31, and each electrode rod 32 is evenly arranged along the edge of the electrode disk 31, and the electrode rods 32 on the electrode disk 31 together form a cage shape, so that the outer edge of the electrode heating assembly is at an equal distance from the inner wall of the corresponding independent area 25, so that the heating of the electrode heating assembly is uniform and the three-phase balance is optimized.

[0037] The electrode rod 32 has a mounting portion 321, a main body portion 322 connected to the mounting portion 321, and a hockey portion 323 connected to the main body portion 322 from top to bottom. The main body portion 322 on the electrode rod 32 is in the shape of an inclined round rod, and the hockey portion 323 is inclined. The inclination angle of the hockey portion 323 toward the center line of the power supply component 30 is greater than the inclination angle of the main body portion 322 toward the center line of the power supply component 30. The hockey portion 323 has an inclined portion 3231 and an end portion 323 connected to the inclined portion 3231. 2. The end 3232 of the hockey stick portion 323 is an arc surface. The diameter of the hockey stick portion 323 increases from top to bottom, so that the profile of the hockey stick portion 323 gradually expands, and the surface area of ​​the hockey stick portion 323 increases, which can reduce the surface current density of the hockey stick portion 323, reduce the tip effect and electrochemical corrosion rate of the hockey stick portion 323, and increase the service life of the electrode rod 32. When heated, the bubbles generated by the electrode rod 32 can rise vertically, and the inclined main body 322 and the hockey stick portion 323 can avoid the trajectory of the bubble rise (such as Fig.10 As shown), the rising bubbles are prevented from hindering the migration of ions heated by the electrode rod 32, thereby ensuring the electrode heating effect.

[0038] Under the tilting action of the main body 322, all the electrode rods 32 on the electrode disk 31 gradually gather toward the center from top to bottom, and the distance from the electrode rods 32 to the inner wall of the independent area 25 from top to bottom gradually increases, and at the same time, the distance of ion migration from the electrode rods 32 to the inner wall of the inner shell 21 is gradually increased, that is, the resistance increases and the current decreases. When the liquid level in the inner cylinder 20 decreases, the electrode rods 32 gradually break away from the contact with the electrolyte aqueous solution from top to bottom, and the resistance in the electrode heating circuit and the magnitude of the current passing through can be controlled by adjusting the liquid level of the inner cylinder 20. In addition, when the electrolyte aqueous solution in the inner cylinder 20 is at a low liquid level, the distance from the electrode rods 32 to the inner wall of the inner shell 21 is also increasing, further increasing the resistance, and reducing the low liquid level operation load of the electrode rods 32.

[0039] The electrode disk 31 is provided with a mounting hole 311, and the electrode rod 32 is inserted into the mounting hole 311. The mounting hole 311 is conical, and the diameter of the mounting hole 311 gradually increases from top to bottom. The mounting portion 321 on the electrode rod 32 is consistent with the mounting hole 311. The center of the mounting portion 321 on the electrode rod 32 is provided with a connecting screw hole 324. The connecting screw hole 324 is threadedly connected with a first bolt that penetrates the mounting hole 311 and is crimped to the electrode disk 31, so that the mounting portion 321 is tightly attached to the mounting hole 311 on the electrode disk 31 to ensure the continuity of current transmission.

[0040] like Figure 2 , Figure 6 , Figure 7 and Figure 9-13 The two power-carrying components are fixedly connected to the two sides of the top surface of the electrode disk 31 respectively. Each power-carrying component includes an electrode porcelain bushing 33, a conductive rod 34 and a connecting seat 35. The conductive rod 34 is connected to the connecting seat 35 through the electrode porcelain bushing 33. Since the electrode porcelain bushing 33 is made of insulating material, the electrode porcelain bushing 33 isolates the conductive rod 34 from the connecting seat 35. There is no electricity between the conductive rod 34 and the connecting seat 35, so that the housing 11 is not charged.

[0041] The outside of the electrode porcelain sleeve 33 has a protrusion 331, and the upper and lower sides of the protrusion 331 both have a first matching spherical surface 332. The center of the electrode porcelain sleeve 33 is a through hole, and the conductive rod 34 is inserted into the through hole on the electrode porcelain sleeve 33. The bottom of the conductive rod 34 is fixedly connected to a connecting block 36 by screws. A first flat gasket made of elastic rubber material is abutted between the connecting block 36 and the electrode porcelain sleeve 33 to seal the connecting block 36 and the electrode porcelain sleeve 33. The connecting block 36 is fixedly connected to the electrode disk 31, and the top of the conductive rod 34 is connected to an external power supply to complete the power-on function.

[0042] The connection seat 35 includes an electrode tube seat 351 sleeved on the outside of the electrode porcelain sleeve 33, the electrode tube seat 351 is threadedly connected to the top of the shell 11, and the electrode tube seat 351 has a limiting boss 3511. The electrode tube seat 351 is sleeved with two sealing rings 352 made of soft rubber arranged up and down. The sealing ring 352 located at the bottom overlaps the limiting boss 3511. The sides facing the two sealing rings 352 both have second matching spherical surfaces 3521. The two second matching spherical surfaces 3521 are respectively connected to the two first matching spherical surfaces 3521. The spherical surface 332 is pressed and sealed. Compared with the plane seal, the arc surface seal can be suitable for spans of different angles. The angle of the electrode porcelain sleeve 33 and the connecting seat 35 can be flexibly adjusted when assembled, and the sealing performance is guaranteed. The space surrounded by the limiting boss 3511 and the two sealing rings 352 is filled with a filler 353, and the filler 353 is made of asbestos. The electrode tube seat 351 is detachably connected to the clamping flange 354 by bolt fasteners, and the bottom of the clamping flange 354 is crimped on the sealing ring 352 located above.

[0043] like Figure 1 , Figure 2 , Fig. 9 and Fig.14 The water supply mechanism 40 includes a first water pump 41. The water inlet end of the first water pump 41 is connected to a water inlet pipe connected to the bottom of the outer cylinder 10. The water outlet end of the first water pump 41 is connected to a water distribution component 42. The water distribution component 42 passes through the inner shell 21 and is placed in the inner shell 21. The first water pump 41 can transport the electrolyte aqueous solution in the outer cylinder 10 to the inner shell 21 through the water inlet pipe.

[0044] By controlling the amount of electrolyte solution input into the inner shell 21, the amount of electrolyte solution evaporation in the inner shell 21 and the amount of electrolyte solution discharged from the drain port 26, the liquid level of the electrolyte solution in the inner shell 21 can be adjusted, thereby controlling the amount of electrode rod 32 submerged, and thereby increasing the workload of the electrode rod 32.

[0045] The water distribution component 42 includes a main pipe 421, which is welded to the bottom of the outer cylinder 10 and extends to the inside of the outer shell 11. The main pipe 421 is detachably connected to three branch pipes 422 through a flange. The three branch pipes 422 are evenly distributed along the circumferential direction of the main pipe 421. One end of each branch pipe 422 away from the main pipe 421 is detachably connected to a vertical pipe 423 through a water pipe joint. The three vertical pipes 423 penetrate the bottom of the inner shell 21 and extend into three independent areas 25 respectively. A plurality of water dispersion holes 4231 are opened on the top of each vertical pipe 423. The use of small holes and thin streams can control the water flow, thereby reducing the water level fluctuation caused by the water pressure, making the water level stable, so as to ensure the stable heating of the electrode rod 32.

[0046] The outside of each vertical tube 423 is also fixedly connected with an insulating baffle 424 made of an insulating material. The insulating baffle 424 is an elliptical plate made of insulating ceramics and is located directly below each electrode rod 32 in the corresponding independent area 25. The insulating baffle 424 is located below the water-scattering hole 4231. The insulating baffle 424 can divert water on the one hand, and on the other hand, it can isolate and insulate the electrode rod 32 from the bottom of the inner shell 21, blocking the bottom of the electrode rod 32 and the bottom of the inner shell 21 from being energized, thereby blocking the hockey stick portion 323 at the bottom of the electrode rod 32 from doing work, avoiding uneven heating caused by excessive current at the bottom of the electrode rod 32, and also suppressing the tip effect at the bottom of the electrode rod 32, thereby reducing the tip electrochemical corrosion rate.

[0047] like Figure 1 and Figure 2As shown, it also includes a water replenishment mechanism 50, which includes a second water pump 51. The water inlet end of the second water pump 51 is connected to an external deoxygenated water source, and the water outlet end of the second water pump 51 is fixedly connected to a water replenishment pipe 52. The water replenishment pipe 52 is fixedly connected to the bottom of the outer tube 10. The second water pump 51 can transport external deoxygenated water into the outer tube 10 to compensate for the steam consumption of the boiler.

[0048] like Figure 1 , Figure 2 and Fig.15 The flow control mechanism 60 includes a butterfly valve 61 fixedly mounted on the drain outlet 26, an insulating coupling 62 is connected to the operating rod of the butterfly valve 61, the insulating coupling 62 is rotatably connected to the housing 11 through a sealed bearing, one end of the insulating coupling 62 is fixedly connected to a handle 63 located outside the housing 11, and the rotation of the control handle 63 can control the operating rod on the butterfly valve 61 through the insulating coupling 62, thereby adjusting the opening size of the butterfly valve 61 to adjust the flow rate of the electrolyte aqueous solution flowing out of the drain outlet 26. On the one hand, as the electrolyte aqueous solution in the inner shell 21 evaporates, water turns into steam and is discharged from the steam outlet pipe 12, while the electrolyte will remain in the inner shell 21 for accumulation, which will inevitably cause the electrolyte concentration in the inner shell 21 to be too high. A flow control mechanism 60 is provided to control the drainage of the drain port 26, so that the electrolyte aqueous solution in the inner shell 21 can flow to the outer shell 11 for circulation to prevent the continuous accumulation of electrolyte in the inner shell 21. On the other hand, by controlling the flow rate of the electrolyte aqueous solution flowing out of the drain port 26, the liquid level of the electrolyte aqueous solution in the inner cylinder 20 can be regulated, thereby adjusting the load of the steam boiler.

[0049] When adjusting the load of the steam boiler, the flow rate of the electrolyte solution flowing out of the drain port 26 is adjusted through the flow control mechanism 60 to adjust the liquid level of the electrolyte solution in the inner shell 21. By controlling the amount of the electrode rod 32 submerged, the amount of the electrode rod 32 participating in the heating work is controlled, thereby increasing the working load of the electrode rod 32.

[0050] In the above embodiment, the electrolyte aqueous solution discharged from the drain port 26 directly flows downward into the housing 11 and cannot be uniformly mixed with the electrolyte aqueous solution in the housing 11. Therefore, a second embodiment is proposed to overcome the above defects.

[0051] like Fig.16 and Fig.17 , which is the second embodiment of the load-adjustable electrode steam boiler of the present invention. The difference from the first embodiment is that, in the second embodiment, a mixing mechanism 80 is also included.

[0052] The mixing mechanism 80 includes a water outlet head 81 connected to the water supply pipe 52 and a support 82 welded to the bottom of the inner wall of the outer shell 11. A swivel 83 is rotatably connected to the inner side of the support 82 through a bearing. A stirring bar 84 is fixedly connected to the swivel 83. The cross-section of the stirring bar 84 is C-shaped, and the concave surface of the stirring bar 84 is directly opposite to the water outlet end of the water outlet head 81. The deoxygenated water supplied into the outer shell 11 by the water outlet head 81 will impact the stirring bar 84, forcing the stirring bar 84 to rotate. The rotation of the stirring bar 84 stirs the electrolyte aqueous solution in the outer shell 11, so that the electrolyte aqueous solution discharged from the drain port 26 is fully mixed with the electrolyte aqueous solution in the outer shell 11, further improving the mixing effect.

[0053] like Fig.18 , is another embodiment of the electrode disk 31 and the electrode rod 32 of the load-adjustable electrode steam boiler of the present invention, which is different from the above embodiment in that the structures of the electrode disk 31 and the electrode rod 32 are different.

[0054] In this embodiment, the electrode disk 31 is in a disc structure, and the cross-section of each electrode rod 32 is rectangular. The mounting hole 311 on the electrode disk 31 is rectangular, and the mounting hole 311 matches the top of the electrode rod 32 so that the top of the electrode rod 32 can be inserted into and confined in the mounting hole 311. The electrode disk 31 adopts a disc structure, so that the electrode heating assembly can adapt to inner cylinders 20 of different specifications, and has greater versatility. The bottom of the electrode rod 32 on the electrode disk 31 shrinks inward, which can reduce the bottom power of the electrode rod 32 when the liquid level is low.

[0055] Since the resistance is inversely proportional to the cross-sectional area of ​​the conductor, the use of an electrode rod 32 with a rectangular cross section can increase the cross-sectional area of ​​the electrode rod 32, can provide more electron channels, and help reduce resistance. At the same time, in the electrochemical process, reducing resistance can reduce energy loss and improve the utilization efficiency of electric energy. The increase in area can reduce the current density to slow down the electrochemical reaction rate. The disc-structured electrode disk 31 and electrode rod 32 can make full use of the space and make the gaps between the electrode rods 32 consistent. In addition, the bottom contraction structure of the electrode rod 32 is easier to achieve in the production process of the disc electrode, and the rectangular flat electrode rod 32 is easier to bend when it is bent.
