Description

Technical Field

[0001] The present invention relates to the technical field of steam reuse for autoclaves, and particularly to a steam reuse device for autoclaves with green energy conservation. Background Art

[0002] In the technical field of waste heat recovery and utilization of autoclaves, efficient heat recovery and stable equipment operation are crucial. As a key equipment for producing aerated concrete and brick building materials, autoclaves generate a large amount of high-temperature steam during operation. After completing the steam curing task, this steam becomes surplus steam, and if the large amount of heat carried by it is not recovered and utilized, it will cause great waste of energy. At the same time, high-temperature condensate also contains considerable energy. Releasing secondary steam through a flash tank to preheat boiler feed water is one of the common and effective waste heat recovery methods.

[0003] However, the spray heat exchangers currently used in the waste heat recovery process face many challenges during operation. The air resistance problem seriously affects the steam flow and heat exchange efficiency. Although the existing technology realizes that air in the steam pipeline needs to be removed before startup and the steam superheat needs to be ensured during operation to prevent premature condensation from forming air resistance, in actual operation, due to the dynamic changes in steam flow rate, pressure, and temperature, it is still difficult to accurately control. For example, when the steam consumption fluctuates due to changes in factory load, it is difficult to stably maintain the steam flow rate and superheat, which is extremely likely to cause air resistance, resulting in poor steam circulation, reduced heat exchange efficiency, and increased energy consumption. Moreover, once air resistance forms, the troubleshooting and solution process is cumbersome and often requires shutdown for maintenance, seriously affecting production continuity;

[0004] The sealing of pipelines is also a key link in the waste heat recovery system. If the pipelines carrying circulating steam leak, it will not only cause steam and heat loss, reduce the waste heat recovery efficiency, increase production costs, but also pose safety hazards. The leakage of high-temperature steam will scald operators, and even cause a fire if it encounters an open flame. Although there are some pipeline sealing detection methods in the existing technology, most of them have problems such as insufficient detection accuracy, complex operation, or inability to monitor in real time. For example, the operation is cumbersome and it is difficult to detect small leakage points; while some methods based on manual inspection are greatly affected by subjective factors and cannot detect leaks in time, leading to the expansion of problems.

[0005] In summary, there are obvious drawbacks in the current autoclave waste heat recovery and utilization system in terms of reducing air resistance of spray heat exchangers and detecting the sealing of steam pipelines. There is an urgent need for innovative technologies to solve these problems in order to improve the waste heat recovery efficiency and ensure the stable and safe operation of the system.

[0006] Therefore, the present invention proposes a steam reuse device for autoclaves with green energy conservation to solve the above problems. Summary of the Invention

[0010] The sealing performance detection component is used to assist in detecting the sealing performance of the pipeline and ensure the stable circulation of the heat exchange steam in the pipeline.

[0011] As an improvement, the air resistance weakening and recovery efficiency increasing component includes a hot fluid inlet part fixedly connected to the spray type heat exchanger shell. The inner end of the hot fluid inlet part is fixedly communicated with an arc-shaped pipe. One end of the arc-shaped pipe away from the hot fluid inlet part is fixedly communicated with a C-shaped connecting pipe. The arc-shaped pipe is clamped and fixed by the clamping member.

[0012] As an improvement, a first through hole is formed through the C-shaped connecting pipe. The arc-shaped pipe and the bottom of the C-shaped connecting pipe are jointly fixedly connected with a first cylindrical barrel. The bottom of the first cylindrical barrel is threadedly connected with a first threaded part.

[0013] As an improvement, a first insertion groove is formed in the first threaded part. An absorbent rod is inserted into the first insertion groove. Above the hot fluid inlet part and on the spray type heat exchanger shell, a hot fluid outlet part is fixedly connected.

[0014] As an improvement, the arc-shaped pipe and two C-shaped connecting pipes are a set of units in the device. The bottom surface of another set of units in the set of arc-shaped pipe and C-shaped connecting pipe units is fixedly connected with a second cylindrical barrel. The bottom of the second cylindrical barrel is threadedly connected with a second threaded part. A second insertion groove is formed in the second threaded part.

[0015] As an improvement, a detection cavity barrel part is inserted into the second insertion groove. A vertical column cavity is formed in the detection cavity barrel part. A blocking ring is fixedly connected to the top of the vertical column cavity.

The perforated sheet is located between the second disc and the third disc. The first disc, the second disc and the third disc are arranged in sequence from top to bottom.

[0017] As an improvement, a reset injection gas pipe is connected through the bottom end of the detection cavity cylinder part, and an electromagnet is fixedly connected to the outer surface of the detection cavity cylinder part.

[0019] As an improvement, magnetorheological fluid is arranged between the first disc and the second disc, between the second disc and the perforated sheet, and between the perforated sheet and the third disc in the vertical column cavity.

[0020] Compared with the prior art, the present invention provides a steam reuse device for an autoclave with green energy conservation, and has the following beneficial effects:

[0021] 1. Through the design of the air resistance weakening and recovery and efficiency enhancement component, the present invention can bring many significant beneficial effects to the overall work:

[0022] Improve the heat exchange efficiency and ensure the smooth flow of steam: This component can effectively respond to the dynamic changes of steam flow rate, pressure and temperature, ensure that the steam always maintains a stable and reasonable flow rate in the pipeline, and avoid the unsmooth flow of steam caused by air resistance; this enables the steam to come into contact with the condensed water sprayed from the spray pipe more fully, and the heat transfer is more efficient, greatly improving the heat exchange efficiency; originally, the low heat exchange efficiency caused by air resistance would lead to the insufficient transfer of steam heat to the cooling water, but this component can change this situation, enabling more heat to be effectively recovered and utilized;

[0023] Enhance the uniformity of heat transfer: The existence of air resistance often causes uneven distribution of steam in the pipeline, which in turn leads to local overheating or overcooling during the heat exchange process. The air resistance weakening and recovery and efficiency enhancement component weakens the air resistance, allows the steam to be evenly distributed in the arc-shaped pipe and C-shaped connecting pipe of the heat exchanger, and conducts a more uniform and stable heat exchange with the cooling water, reducing the local temperature difference, improving the stability and consistency of the entire heat exchange process, and further enhancing the quality and efficiency of heat recovery;

[0024] Improve production continuity and avoid shutdown for maintenance: Once air blockage forms, the troubleshooting and solution process is usually very cumbersome and often requires shutdown for maintenance, which will seriously affect production continuity. The air blockage weakening, recovery and efficiency enhancement component can effectively prevent the generation of air blockage. Even under the condition of large fluctuations in steam parameters, it can ensure the normal circulation of steam, avoid shutdown for maintenance caused by air blockage, ensure the continuous and stable progress of the production process, and reduce production losses caused by shutdown.

[0025] Reduce potential safety hazards: Air blockage caused by poor steam circulation will lead to abnormal increase in pipeline pressure, increasing the risk of safety accidents such as pipeline rupture and steam leakage. The air blockage weakening, recovery and efficiency enhancement component ensures the normal circulation of steam, maintains stable pipeline pressure, effectively reduces these potential safety hazards, and guarantees the personal safety of operators and the safe operation of equipment.

[0026] 2. The present invention conveys steam by using an arc-shaped pipe, that is, the pipe for transmitting hot steam is designed to be arc-shaped to reduce air blockage. This design has many advantages:

[0027] Reduce air blockage, improve efficiency and drain water smoothly: The water condensed from steam will accumulate at both ends of the arc-shaped pipe, which enables the condensed water to flow naturally to both ends by gravity, rather than being easily accumulated at the bottom of the pipe as in a straight pipe, hindering the normal flow of steam. Thus, it effectively reduces air blockage, ensures smooth steam transmission, and maintains the efficient operation of the system;

[0028] Reduce pressure loss: The reduction of air blockage means that the resistance suffered by steam during flow in the pipeline becomes smaller, and the pressure loss is also correspondingly reduced; this helps to maintain stable pressure of steam in the pipeline, enables steam to be transmitted to the required place more effectively, and reduces energy loss;

[0029] Facilitate maintenance and prevent corrosion: If the condensed water accumulates in the pipeline for a long time, it will chemically react with impurities in the steam, corroding the inner wall of the pipeline. The cooperation of the arc-shaped pipe and the water absorption rod can make the condensed water flow to both ends and be absorbed and discharged, reducing the contact time of the condensed water with the inner wall of the pipeline, thereby reducing the risk of pipeline corrosion and improving the reliability and safety of the pipeline.

[0030] 3. The present invention adopts an arc-shaped pipe in an arc state, improving its contact area. When conveying steam, this design will bring the following benefits to the overall work in terms of heat exchange efficiency, system stability, and temperature control:

[0031] Enhance the heat exchange effect and improve the heat transfer efficiency: A larger contact area means more heat transfer paths and a larger heat transfer area between the steam and the cooling water. According to the principles of heat transfer, this will make the heat transfer more sufficient and efficient, effectively improving the ability of the spray heat exchanger to transfer the steam heat to the cooling water, causing the cooling water to heat up faster and reach a higher temperature, better meeting the process requirements;

[0032] Promote thermal equilibrium and improve temperature uniformity: Increasing the contact area helps the steam and the cooling water to reach the thermal equilibrium state more quickly, making the entire heat exchange process more stable and uniform, reducing the situation of local overheating or overcooling, and improving the quality and effect of heat exchange; moreover, the larger contact area makes the heat distribution in the cooling water more uniform, avoiding the situation of local overhigh or overlow temperature, improving the temperature uniformity of the hot water, and providing a more stable and high-quality hot water resource for the subsequent process.

[0033] 4. Through the design of the sealing detection component, the present invention can bring many significant beneficial effects to the overall work:

[0034] Improve the waste heat recovery efficiency and prevent steam leakage losses: By accurately detecting the airtightness of the steam transmission pipeline, leakage points can be discovered and repaired in a timely manner. It avoids the heat loss caused by steam leakage during the transmission process, enabling more steam to participate in the heat exchange link, increasing the total amount of waste heat recovery, and thus improving the efficiency of the entire waste heat recovery system. For example, if a tiny leakage point is not discovered, a large amount of steam will be lost after long-term accumulation, while the detection component can effectively prevent such situations;

[0035] Stabilize the steam flow rate and pressure: A pipeline with good airtightness can ensure the stability of the steam flow rate and pressure during transmission. Stable steam parameters help the air resistance weakening and recovery efficiency enhancement component to better play its role, maintaining a stable flow rate and superheat degree of the steam in the pipeline, further optimizing the heat exchange efficiency, forming a virtuous cycle, and improving the waste heat recovery efficiency;

[0036] Reduce the workload of preventive maintenance: By regularly using the sealing detection component to detect the pipeline, potential leakage problems can be discovered and solved in a timely manner, eliminating the potential trouble at the embryonic stage. This reduces the emergency repairs and large-scale preventive maintenance work required due to sudden leakage accidents, reduces the maintenance cost, and also reduces the production interruption time caused by equipment repairs.

[0037] 5. In the present invention, the sealing detection component has many advantages compared with the spring component by adopting the design of an electromagnet cooperating with magnetorheological fluid, specifically as follows:

[0038] In terms of detection accuracy; not affected by fatigue effect: Springs will experience metal fatigue after multiple expansions and contractions, resulting in changes in the elastic coefficient, relaxation, and inaccurate detection results. However, the design of the electromagnet combined with magnetorheological fluid has no fatigue problem. The mechanical properties of magnetorheological fluid are stable under the action of a magnetic field. As long as the electromagnetic parameters and the characteristics of the magnetorheological fluid are stable, the resistance to the push piece can be ensured to be consistent during each detection, making the detection results more reliable and accurate;

[0039] Can accurately regulate the resistance: The electromagnet can adjust the magnetic field strength by precisely controlling the current, and then accurately adjust the mechanical properties of the magnetorheological fluid, that is, the viscosity, to achieve precise regulation of the resistance to the push piece. In contrast, the elastic force of a spring is determined by its material and structure, and it is difficult to make flexible and precise adjustments during the detection process, unable to meet the requirements for precise control of resistance in different detection scenarios;

[0040] In terms of service life and stability: Springs will deform and break after long-term use, requiring regular replacement, increasing the maintenance cost and the downtime of the detection system; The combination of the electromagnet and the magnetorheological fluid has no problems of mechanical wear and fatigue aging. As long as the performance of the electrical components and the liquid is ensured to be stable, it can work stably for a long time, greatly extending the service life of the detection components;

[0041] Strong anti-environmental interference ability: The performance of springs is greatly affected by environmental factors such as temperature and humidity, and elastic changes will occur in different environments. The performance of electrorheological fluid and electromagnet is relatively stable and less affected by environmental factors, and can maintain good detection performance in different working environments, improving the stability and adaptability of the detection system.

[0071] The sealing detection component 8 is used to assist in detecting the sealing of the pipeline, ensuring the stable flow of the heat exchange steam in the pipeline. The arc-shaped pipe 702 and the two C-shaped connecting pipes 703 are a group of units in the device. The bottom surface of another group of units in the set of the arc-shaped pipe 702 and the C-shaped connecting pipe 703 is fixedly connected with a second cylindrical barrel 801.

The first circular plate 807, the second circular plate 808, and the third circular plate 810 are arranged in sequence from top to bottom. The bottom end of the detection cavity barrel part 804 is connected through with a reset injection air pipe 811. An electromagnet 812 is fixedly connected to the outer surface of the detection cavity barrel part 804.

[0072] Among them:

[0073] The sealing detection component 8 is used to assist in detecting the sealing of the pipeline, ensuring the stable flow of the heat exchange steam in the pipeline.

[0074] The second cylindrical barrel 801 and the detection cavity barrel part 804 are made of a transparent material, which can be implemented as toughened glass.

[0075] The inner diameter of the vertical column cavity 805 is the same as the outer diameters of the blocking ring 806, the first circular plate 807, the second circular plate 808, the perforated plate 809, and the third circular plate 810.

[0076] Magnetorheological fluid is provided between the first circular plate 807 and the second circular plate 808, between the second circular plate 808 and the perforated plate 809, and between the perforated plate 809 and the third circular plate 810 in the vertical column cavity 805.

[0077] The reset injection air pipe 811 is mainly used for the reset work of the third circular plate 810 and the magnetorheological fluid in the vertical column cavity 805.

[0078] The electromagnet 812 can adjust the magnetic field strength by precisely controlling the current, and then accurately adjust the mechanical properties of the magnetorheological fluid, that is, the viscosity, to achieve precise control of the pushing resistance of the push plate.

[0079] The reset injection gas pipe 811 can be filled with gas externally to cooperate with the reset of the third wafer 810.

[0080] The sealing detection component 8 can be increased or decreased in the device according to the specific usage situation.

[0081] The working principle of all the contents in the above embodiments is as follows:

[0082] In the initial state:

[0083] The water absorption rod 708 plugs the first through hole 704, and the electromagnet 812 is not powered on.

[0084] The following is the working process of the gas resistance weakening, recovery and efficiency increasing component 7:

[0085] During use, steam will flow into the pipeline unit composed of the arc tube 702 and the C-shaped connecting tube 703 from the hot fluid inlet part 701, and finally flow out through the hot fluid outlet part 709. During this process, if the steam is partially liquefied in the arc tube 702 and the C-shaped connecting tube 703 under the action of the water sprayed by the spray pipe 2, due to the shape design of the arc tube 702 and the C-shaped connecting tube 703, the water will flow to the connecting corner of the arc tube 702 and the C-shaped connecting tube 703 under the action of gravity. For reference, see the appendix Figure 5 , at this time, the water absorption rod 708 blocking the first through hole 704 will absorb the water liquefied from the steam; it should be noted that the operator can replace the water absorption rod 708 in the first plug-in slot 707 by rotating the first threaded part 706 on the first cylindrical tube 705 according to the working conditions;

[0086] Furthermore, by using the arc tube 702 to convey steam, that is, designing the pipeline for transmitting hot steam into an arc shape to reduce gas resistance. This design reduces gas resistance and improves efficiency, and drains water smoothly: the water condensed from the steam will gather at both ends of the arc tube 702, which enables the condensed water to flow naturally to both ends of the pipeline by gravity, rather than being easily accumulated at the bottom of the pipeline like in a straight pipe, hindering the normal flow of steam. Thus, it effectively reduces gas resistance, ensures the smooth transmission of steam, and maintains the high-efficiency operation of the system;

[0087] Reducing pressure loss: The reduction of gas resistance means that the resistance suffered by the steam flowing in the pipeline becomes smaller, and the pressure loss is also correspondingly reduced; this helps to maintain the pressure stability of the steam in the pipeline, enables the steam to be more effectively transmitted to the required place, and reduces energy loss;

[0088] Easy to maintain and prevent corrosion: If condensate accumulates in the pipeline for a long time, it will chemically react with the impurities in the steam, corroding the inner wall of the pipeline. The cooperation of the arc-shaped pipe 702 and the water absorption rod 708 can make the condensate flow to both ends and be absorbed and discharged, reducing the contact time between the condensate and the inner wall of the pipeline, thus reducing the risk of pipeline corrosion and improving the reliability and safety of the pipeline.

[0089] Furthermore, by adopting the arc-shaped pipe 702 in an arc state, its contact area is improved. When transporting steam, this design will bring the following benefits to the overall work in terms of heat exchange efficiency, system stability, and temperature control:

[0090] Enhance the heat exchange effect and improve the heat transfer efficiency: A larger contact area means more heat transfer paths and a larger heat transfer area between the steam and the cooling water. According to the principles of heat transfer, this will make the heat transfer more sufficient and efficient, effectively improving the ability of the spray-type heat exchanger to transfer the heat of the steam to the cooling water, making the cooling water heat up faster and reach a higher temperature, and better meeting the process requirements;

[0091] Promote thermal equilibrium and improve temperature uniformity: Increasing the contact area helps the steam and the cooling water reach the thermal equilibrium state more quickly, making the entire heat exchange process more stable and uniform, reducing the situation of local overheating or overcooling, and improving the quality and effect of heat exchange; and a larger contact area makes the distribution of heat in the cooling water more uniform, avoiding the situation of local overhigh or overlow temperature, improving the temperature uniformity of the hot water, and providing a more stable and high-quality hot water resource for the subsequent process.

[0092] Please refer to the above working process Figures 1 to 5 .

[0093] The following is the working process of the sealing detection component 8:

[0094] Furthermore, when the waste heat of the steam is not recovered and utilized, the airtightness of the pipeline composed of the hot fluid inlet part 701, the arc-shaped pipe 702, the C-shaped connecting pipe 703, and the hot fluid outlet part 709 can be detected. At this time, the second threaded part 802 with the detection cavity cylinder part 804 can be installed on the second cylindrical cylinder 801 through the knob action. Then, the hot fluid outlet part 709 is blocked, and air is injected into the hot fluid inlet part 701, the arc-shaped pipe 702, and the C-shaped connecting pipe 703 through an external air pump. At this time, the electromagnet 812 is energized. Furthermore, under the action of the gas, the gas will gradually fill the pipeline, and in the continuous inflation process, it will push the first disc 807. The first disc 807 will push the second disc 808 through the magnetorheological fluid during the pushing process, and the same is true for the second disc 808. At this time, the magnetorheological fluid will push the third disc 810 through the through holes on the perforated sheet 809. During the whole process, the energized electromagnet 812 will prevent the flow of the magnetorheological fluid in the vertical column cavity 805 under the action of the magnetic force. As is known, the electromagnet 812 can adjust the magnetic field strength by precisely controlling the current, and then precisely adjust the mechanical properties of the magnetorheological fluid, that is, the viscosity, to achieve precise control of the resistance of the pushing piece. That is, the operator can judge whether there is an airtightness problem in the pipeline at this time by adjusting the standard air injection volume and observing the distance of the third disc 810 in the vertical column cavity 805. It should be noted that under normal conditions, there should be a corresponding exact position of the third disc 810 in the vertical column cavity 805 for a gas injection volume; if there is an airtightness problem, the vertical column cavity 805 will not move to the exact corresponding position;

[0095] Furthermore, the sealing detection component 8 has many advantages in design by using the electromagnet 812 in cooperation with the magnetorheological fluid compared with the spring component, as follows: In terms of detection accuracy; not affected by fatigue effect: The spring will show metal fatigue after multiple expansions and contractions, resulting in changes in the elastic coefficient and relaxation, and then making the detection result inaccurate. However, the design of the electromagnet 812 in cooperation with the magnetorheological fluid has no fatigue problem. The mechanical properties of the magnetorheological fluid are stable under the action of the magnetic field. As long as the electromagnetic parameters and the characteristics of the magnetorheological fluid are stable, it can ensure that the resistance to the pushing piece is consistent during each detection, making the detection result more reliable and accurate;

[0096] The resistance can be precisely regulated: The electromagnet 812 can adjust the magnetic field strength by precisely controlling the current, and then precisely adjust the mechanical properties of the magnetorheological fluid, that is, the viscosity, to achieve precise control of the resistance of the pushing piece; In contrast, the elastic force of the spring is determined by its material and structure, and it is difficult to make flexible and precise adjustments during the detection process, and it cannot meet the requirements for precise control of the resistance in different detection scenarios;

[0097] In terms of service life and stability: After long-term use, the spring will deform and break, and needs to be replaced regularly, which increases the maintenance cost and the downtime of the detection system. The combination of the electromagnet 812 and the magnetorheological fluid has no problems of mechanical wear and fatigue aging. As long as the performance of the electrical components and the liquid is stable, it can work stably for a long time, greatly extending the service life of the detection component.

[0098] Strong anti-environmental interference ability: The performance of the spring is greatly affected by environmental factors such as temperature and humidity, and elastic changes will occur in different environments. The performance of the electrorheological fluid and the electromagnet is relatively stable and less affected by environmental factors, and can maintain good detection performance in different working environments, improving the stability and adaptability of the detection system.
