Description

TECHNICAL FIELD

[0001] The present application relates to the field of boiler decoking technology, in particular to a steam device suitable for boiler decoking. BACKGROUND

[0002] As an important heat energy equipment, boilers are widely used in power, chemical, metallurgical and other industries, and undertake the tasks of heating, steam generation and heat supply. In the long-term operation process, a large amount of fouling is produced in the combustion process inside the boiler. These fouling is mainly due to the accumulation of minerals and impurities in the fuel under high temperature environment. The fouling will adhere to the heating surface, heating pipes and steam generator of the boiler, which not only reduces the thermal efficiency of the boiler, but also may cause corrosion, pipe explosion and scaling problems of the boiler, thereby affecting the safety and economy of the boiler.

[0003] In order to ensure the long-term stable operation of the boiler, regular decoking operation must be carried out. The traditional boiler decoking method includes mechanical cleaning, chemical cleaning and high-temperature steam flushing. Although the mechanical cleaning and chemical cleaning methods can remove the fouling to some extent, they often have some side effects, such as damaging the internal structure of the boiler or using toxic chemicals to pollute the environment.

[0004] Therefore, it has important practical significance to study a steam device suitable for boiler decoking. The fouling on the inner wall and pipeline of the boiler can be removed by high-pressure and high-temperature steam injection, which not only avoids the potential risks of traditional cleaning methods, but also efficiently and quickly restores the heat exchange capacity of the boiler, improves the operation efficiency of the boiler and prolongs the service life of the boiler.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention, by setting up a temporary storage component and a triggering component in combination, can achieve stable storage and precise release of steam, effectively solving the problems of reduced thermal efficiency and equipment damage that are easily caused by traditional methods during boiler descaling. By setting up a temporary storage component to temporarily store steam and stabilize pressure, thermal shock caused by instantaneous steam release can be avoided; at the same time, the adjustable triggering component allows operators to control the direction of steam injection, thereby reducing the direct contact of high-temperature steam with the internal structure of the boiler and reducing the risk of thermal shock.

[0019] 2. This invention achieves steam generation and storage through the cooperation of steam components and temporary storage components, providing a stable pressure source for subsequent coking. By setting a controller, operators can monitor the internal pressure of the temporary storage components in real time, ensuring that the predetermined coking pressure value is reached before operation, thus avoiding damage to the equipment caused by excessive pressure. By setting the adjustable length and angle of the trigger component, the precise injection of high-temperature steam is ensured, thereby reducing thermal shock and damage to the boiler structure and extending the service life of the equipment.

[0020] 3. This invention, through the combination of gas acceleration blocks and turbulence blocks, can achieve efficient acceleration and kinetic energy enhancement of steam, significantly improving the decoking effect. By setting the diversion and merging structure inside the gas acceleration block, the steam can generate an acceleration effect during multiple diversions and merging processes, increasing the ejection speed. This high-speed steam impact can not only instantly break up stubborn coke layers, but also induce internal cracks in the coke deposits through vibration and stress waves. At the same time, it can disintegrate the adhesion of coke deposits by using the penetrating force of high-speed fluid, greatly improving cleaning efficiency and thoroughness.

[0021] 4. This invention, through the cooperation of the sliding shell and springs two and three, enables flexible release and rapid reset of steam, improving operational convenience and descaling efficiency. By setting the precise cooperation between the sliding shell and the release port, the steam flow rate and injection angle can be flexibly adjusted to meet the cleaning needs of different types of coke. This design reduces the complexity of traditional manual control, improves the response speed and accuracy of descaling operations, and is suitable for boiler descaling scenarios under complex operating conditions.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1, please refer to Figure 1 and Figure 2 As shown, a steam device suitable for boiler descaling includes a movable base 1, a steam component 2 fixedly connected to the upper end of the movable base 1, a temporary storage component 5 fixedly connected to the upper end of the steam component 2, two fixing rings 4 fixedly connected to the upper end of the movable base 1, a trigger component 6 fixedly connected to the upper part of the temporary storage component 5, and a controller 3 fixedly connected to both the fixing rings 4 and the upper end of the movable base 1.

[0036] In the implementation of this embodiment, when the operator uses the device for the first time, an appropriate amount of solution needs to be added to the inner cavity of the steam component 2 so that steam will be generated during subsequent heating. After the heating mechanism inside the steam component 2 causes the added solution to generate steam, the steam will enter the temporary storage component 5 for temporary storage. Then, the operator can observe the pressure inside the temporary storage component 5 in real time through the controller 3. When the predetermined decoking pressure value is reached, the operator can remove the trigger component 6 from the front snap-fit ​​of the steam component 2 and insert the trigger component 6 into the boiler that needs to be decoked. The trigger mechanism inside the trigger component 6 will then be activated to decoke the inner cavity of the boiler. In addition, during the decoking process, the operator can also adjust the components inside the trigger component 6 to adjust its length and angle, thereby avoiding direct contact between the high-temperature steam inside the boiler and the vulnerable parts of the boiler, reducing the thermal shock and damage to the boiler structure.

[0037] The solutions mentioned above can be water, ammonium hydroxide solution, and acidic solution. Water is the most common choice, as it evaporates into steam during heating, making it suitable for general decoking needs. Water is inexpensive, readily available, and does not cause additional corrosion to the boiler's internal structure. Ammonium hydroxide solution can be used to remove certain types of carbonate or phosphate coke deposits. For some stubborn mineral coke deposits, calcium deposits, and magnesium deposits, operators can use diluted acidic solutions to dissolve these minerals. It should be noted that operators must take special care to prevent corrosion when using acidic solutions to avoid causing corrosion to the boiler's internal metal structure.

[0038] Furthermore, the controller 3 mentioned above is a conventional technical means in the prior art. In this solution, it is only used for its function of real-time monitoring and control. Its working principle and circuit connection will not be elaborated in detail here.

[0039] By cooperating with the steam assembly 2 and the temporary storage assembly 5, steam is generated and stored, providing a stable pressure source for subsequent coking. By setting the controller 3, the operator can monitor the internal pressure of the temporary storage assembly 5 in real time, ensuring that the predetermined coking pressure value is reached before operation, thus avoiding damage to the equipment caused by excessive pressure. By setting the adjustable length and angle of the trigger assembly 6, the high-temperature steam is accurately injected, thereby reducing the thermal shock and damage to the boiler structure and extending the service life of the equipment.

[0040] Example 2, this example achieves the purpose of heating the solution based on Example 1. Please refer to [link / reference]. Figure 3 As shown, the steam assembly 2 includes a housing 21, an insulation plate 22 fixedly connected inside the housing 21, a heating plate 23 fixedly connected to the upper end of the insulation plate 22, a heat-conducting coil 24 fixedly connected to the upper end of the heating plate 23, a storage box 25 fixedly connected to the middle of the inner cavity of the housing 21, a heat-conducting coil 24 cooperating with the heat-conducting coil 24 is provided at the bottom of the storage box 25, two fixing buckles 26 are fixedly connected to the front of the outer surface of the housing 21, the two fixing buckles 26 are fixedly connected to the temporary storage assembly 5, a blocking plate 27 is slidably connected to the upper end of the storage box 25, a spring 28 is fixedly connected to the upper end of the blocking plate 27, and a fixing plate 29 is fixedly connected to the other side of the spring 28.

[0041] When the operator uses this device for the first time, an appropriate amount of solution should be added to the inner cavity of the storage tank 25. The controller 3 will then control the circuit board installed inside the heat insulation plate 22, causing current to flow through the heating element inside the heating plate 23. According to Joule's law, the resistance wire generates heat due to its own resistance. This heat is directly conducted to the solution inside the storage tank 25 through the heat-conducting coil 24. Simultaneously, the water in the storage tank 25 will experience convection due to uneven heating; the heated water at the bottom will rise, while the cooler water at the top will sink. This cycle continuously raises the temperature of the entire tank of water, thus achieving heating. Once the solution reaches its boiling point, steam will be generated. Since the inner cavity of the storage tank 25 is a closed cavity, the steam inside will be pushed upwards, causing the blocking plate 27 to slide upwards. The spring 28, under this force, will be compressed, releasing a certain amount of steam. This released steam will enter the temporary storage component 5, and this cycle will continue until the entire inner cavity of the temporary storage component 5 is filled.

[0042] When the overall volume of the storage tank 25 is insufficient to push the blocking disk 27 upward, the spring 28 will, according to its own characteristics, push the blocking disk 27 downward to prevent the steam in the storage component 5 from flowing back.

[0043] By setting up the storage tank 25 and the heating plate 23, the solution is heated and steam is generated. Through the action of the current heating element and Joule's law, the solution is heated evenly and steam is generated, ensuring the stability of the steam pressure. Through the design of the blocking plate 27 and the spring 28, the amount of steam released can be precisely controlled to avoid steam backflow, thereby protecting the stability and safety of the temporary storage component 5 and ensuring the efficient and safe operation of the equipment.

[0044] Example 3, based on Examples 1 and 2, demonstrates how to release steam. For further details, please refer to [link to example 3]. Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the temporary storage component 5 includes a temporary storage box 51, the inner cavity of which communicates with the inner cavity of the storage box 25. A connecting tube 52 is fixedly connected to the right side of the temporary storage box 51, and a mating component 54 is fixedly connected to the other end of the connecting tube 52. A sensor 53 is fixedly connected to the outer surface of the connecting tube 52. The mating component 54 includes a connecting tube 541, a fixing tube 542 is fixedly connected to the inner cavity of the connecting tube 541, and a spring 544 is fixedly connected to the upper end of the fixing tube 542. Four release ports 543 are provided on the upper part of the fixing tube 542. The outer surface of the connecting tube 541 is snapped into the inner surface of the two fixing rings 4. The trigger component 6 includes a housing 61, and the inner surface of the housing 61 has a sliding mechanism. The moving connection includes a second mating component 62, and a first sliding component 63 is slidably connected to the outer surface of the second mating component 62. An acceleration component 64 is slidably connected to the inner surface of the first sliding component 63. The second mating component 62 includes a sliding block 621, which is slidably connected to the second outer shell 61. A fixed rod 622 is fixedly connected to one side of the sliding block 621, and a connecting block 623 is fixedly connected to the bottom of the fixed rod 622. A third spring 624 is fixedly connected to the bottom of the connecting block 623, and the other side of the third spring 624 is fixedly connected to the inner cavity of the second outer shell 61. A first sliding shell 625 is fixedly connected to the upper end of the connecting block 623, and the inner cavity of the first sliding shell 625 is slidably connected to the outer surface of the release port 543.

[0045] In this embodiment, when the steam in the inner cavity of the temporary storage tank 51 reaches a threshold, the sensor 53 will send a signal to the controller 3, causing the controller 3 to stop the heating coil 24 from heating the storage tank 25. Subsequently, the steam in the inner cavity of the temporary storage tank 51 will enter the inner cavity of the connecting pipe 52 and then the inner cavity of the fixed pipe 542. When the operator wants to spray steam, they only need to press the sliding block 621. During the sliding process, the sliding block 621 will drive the connecting block 623 to move downward, thereby compressing the spring 624. At this time, the upper part of the connecting block 623... The fixedly connected sliding shell 625 will slide downwards along with the connecting block 623. During the sliding process, it will compress the fixed spring 544 544 542 542. After the sliding shell 625 slides to a specific position, it will release the restriction on the four release ports 543. At this time, the steam in the inner cavity of the connecting pipe 541 will be ejected in the form of an explosion and enter the inner cavity of the sliding shell 625. Since the inner cavity of the sliding shell 625 is inclined, the steam can change direction and be discharged from the inner cavity of the sliding shell 625 to enter the next stage.

[0046] When the operator releases the sliding block 621, the second spring 544 and the third spring 624 will push the first sliding shell 625 and the connecting block 623 to move under their own characteristics, thereby causing the sliding block 621 to reset.

[0047] Through the cooperation of sliding block 621, connecting block 623, sliding shell 625, spring 544, and spring 624, the release of steam can be flexibly controlled, ensuring that steam is ejected efficiently in an explosive manner to meet different operational needs. Steam release is achieved by simply pressing the sliding block, reducing operational complexity and improving ease of use. The coordinated work of each component makes the entire steam release process stable and controllable, improving operational safety and efficiency. It is suitable for application scenarios that require precise steam control and helps to improve the stability and automation level of the system.

[0048] Example 4 further implements the adjustment of the length and angle of the trigger component 6 based on Examples 1, 2, and 3. Please refer to [link to example 4]. Figure 8 , Figure 9 and Figure 10 As shown, the sliding component 63 includes a housing 631, with a sliding cavity 632 inside the housing 631. The inner cavity of the sliding cavity 632 is slidably connected to the outer surface of the sliding shell 625. A sliding cavity 633 is formed on the upper part of the housing 631, and a plurality of sliding cavities 634 are formed on the inner surface of the sliding cavity 633. The acceleration component 64 includes a connecting pipe 641, with a gas acceleration block 642 fixedly connected to the inner surface of the connecting pipe 641. A nozzle 643 communicating with the inner cavity of the gas acceleration block 642 is fixedly connected to the upper part of the outer surface of the connecting pipe 641. A sliding assembly 644 is fixedly connected to the bottom of the inner cavity of tube 3 641. The sliding assembly 644 includes a sliding shell 6441. Several springs 6445 are fixedly connected to the outer surface of the sliding shell 6441. A slider 6444 is fixedly connected to the side of each spring 6445 that is far away from each other. Each slider 6444 cooperates with the corresponding sliding cavity 3 634. A connecting tube 6442 is fixedly connected to the bottom of connecting tube 3 641. A hemispherical tube 6443 is fixedly connected to the bottom of connecting tube 6442. The hemispherical tube 6443 cooperates with the inner cavity of sliding cavity 1 632.

[0049] Furthermore, in this embodiment, when the operator wants to adjust the length and angle of the trigger component 6, they only need to rotate the connecting pipe 641 and then pull it. During the pulling process, several sliders 6444 slidably connected at the bottom of the connecting pipe 641 will slide synchronously, thereby squeezing the corresponding fixedly connected spring 6445. At this time, the operator only needs to pull the connecting pipe 641 to extend to a predetermined distance. Then the sliders 6444 will stop at a point inside the sliding cavity 634. During the pulling process, the connecting pipe 6442 fixed at the gas acceleration block 642 will drive the hemispherical tube 6443 to move together. Due to its own characteristics, the hemispherical tube 6443 will not cause steam leakage at the sliding shell 625 during its movement inside the sliding cavity 632. Then, the steam will enter the gas acceleration block 642 through the hemispherical tube 6443 and the connecting pipe 6442. During this process, the steam will be further accelerated, making the decoking process smoother for the operator.

[0050] Through the cooperation of connecting pipe 641, slider 6444, spring 6445, and hemispherical tube 6443, the operator can easily adjust the length and angle of the trigger component 6 to meet different operational needs. During the adjustment process, the cooperation of slider 6444 and spring 6445 ensures the smoothness and precision of the action and avoids steam leakage. At the same time, through the coordinated work of hemispherical tube 6443 and gas acceleration block 642, the steam flow is effectively accelerated, making the decoking process smoother and more efficient.

[0051] Please see Figure 11 The inner cavity of the gas accelerator block 642 is connected to the inner cavity of the connecting pipe 6442, and the inner cavity of the gas accelerator block 642 is provided with several interference flow blocks.

[0052] Further explanation is needed: After the steam enters from point a, it will continue forward from point b. When the steam reaches point c, a small portion of the steam will be split, and this split gas will re-enter point a via point d. Subsequently, it will follow the steam that entered from a back into point b. During the process of the steam merging at point d, it will accelerate the steam entering from point a, increasing its speed. Meanwhile, another portion of the gas separated from point c will also be split at point e, and a small portion of the steam will re-enter from point f, accelerating the steam entering from point a. This cycle repeats continuously.

[0053] When the steam is ejected from point g, it will burst out along nozzle 643, releasing the steam for decoking in a very short time. This instantaneous release generates a powerful impact force and kinetic energy, which can instantly shatter the coke layer structure with the enormous pressure during decoking operations. At the same time, the vibration and stress waves caused by the high-speed fluid during the impact will cause cracks inside the coke, accelerating its detachment. Furthermore, the burst-ejected medium can quickly penetrate into the tiny gaps between the coke and the equipment surface, breaking down the adhesion of the coke, thereby efficiently and thoroughly removing all kinds of stubborn coke. Compared with traditional slow spraying or manual cleaning methods, this greatly improves the decoking efficiency and cleaning effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
