Description

Technical Field

[0001] This utility model belongs to the field of energy utilization equipment technology, and in particular relates to a hot water steam conversion device. Background Technology

[0002] Industrial production processes typically generate significant amounts of waste heat, which carries substantial energy and can be reused, thus bringing energy-saving benefits to enterprises. This effectively reduces production costs and environmental pollution. However, current waste heat utilization efficiency is low, and the required equipment is expensive, making it difficult for some enterprises to equip themselves with such systems. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model discloses a hot water steam conversion device that can effectively convert hot water into steam with high conversion efficiency, which is beneficial for enterprises to utilize waste heat.

[0004] The specific technical solution of this utility model is as follows:

[0005] A hot water steam conversion device, comprising:

[0006] A separation mechanism, comprising a first steam chamber, a separation chamber, and a second steam chamber, wherein high-temperature water is introduced into the separation chamber and the steam generated by the high-temperature water enters the second steam chamber;

[0007] A pressure relief mechanism, comprising a high-pressure medium chamber for introducing a high-pressure medium and a low-pressure medium chamber for discharging a low-temperature medium; and

[0008] A transfer mechanism, wherein the transfer mechanism is provided with a core tube, and a piston is movably disposed inside the core tube;

[0009] Wherein, the separating mechanism and the pressure-releasing mechanism can rotate relative to the transfer mechanism, or the transfer mechanism can rotate relative to the separating mechanism and the pressure-releasing mechanism;

[0010] During rotation, the core tube switches between the first steam chamber and the second steam chamber, as well as between the high-pressure medium chamber and the low-pressure medium chamber.

[0011] After the high-temperature water enters the separation chamber, it generates high-temperature steam. This steam then enters the second steam chamber and the core tube, pushing the piston towards the pressure relief mechanism and storing the steam within the core tube. This drives the corresponding mechanism to rotate. The core tube is connected to the first steam chamber and the high-pressure medium chamber. The high-temperature medium entering the high-pressure medium chamber pushes the piston towards the separation mechanism, discharging the steam stored in the core tube through the first steam chamber. After rotating again, the core tube connects to the low-pressure medium chamber, allowing the high-temperature medium entering the core tube to be discharged through the low-pressure medium chamber. Meanwhile, the high-temperature water, after cooling, is also discharged from the second steam chamber. By operating in this manner, the need for waste heat utilization can be met. Based on the above process, the conversion device provided in this application has a simple structure, low cost, convenient operation, and high conversion efficiency.

[0012] Preferably, the separation mechanism is divided into multiple chambers in a circumferential direction, one of which is a first steam chamber, and the other chambers are divided into a separation chamber and a second steam chamber;

[0013] A steam conduit is installed between the separation chamber and the second steam chamber in the same chamber, and a water pipe is connected between any adjacent separation chambers;

[0014] The first steam chamber is equipped with an exhaust port;

[0015] One of the separation chambers adjacent to the first steam chamber is equipped with a high-temperature water inlet, and the other separation chamber adjacent to the first steam chamber is equipped with a low-temperature water outlet.

[0016] The separation mechanism is divided into multiple separation chambers and corresponding multiple second steam chambers, so that after the high-temperature water enters, steam with different gradient temperatures and / or pressures can be formed, thereby enabling the collection of steam of different qualities. In addition, after driving the corresponding mechanism to rotate, the steam of the previous stage can be used to pressurize the steam of the next stage, thereby providing the quality of the steam of the next stage and collecting higher quality steam.

[0017] Preferably, the chambers in the separation mechanism are evenly divided; the separation chamber is located above the second steam chamber.

[0018] When high-temperature water enters the separation chamber, the steam moves upward. To prevent high-temperature water leakage, when the separation chamber is located above the second steam chamber, the steam conduit extends to the top of the separation chamber. This allows the steam to flow from the steam conduit into the second steam chamber after the steam is pressurized. This structure is simple and practical.

[0019] Preferably, the radial area of ​​the high-pressure medium chamber separated by the pressure relief mechanism is equal to the radial area of ​​the low-pressure medium chamber, and is also equal to the radial area of ​​the chamber of the separation mechanism.

[0020] In this application, the radial area of ​​the chamber is consistent with that of the high-pressure medium chamber and the low-pressure medium chamber, so that after the corresponding mechanism rotates, the corresponding connection of the core tube can be realized, thereby enabling the piston to perform its due function.

[0021] Preferably, the high-pressure medium chamber and the low-pressure medium chamber are arranged adjacent to each other.

[0022] When the high-pressure medium chamber and the low-pressure medium chamber are arranged adjacent to each other, the rotation of the corresponding mechanism can better realize the storage of steam in the core tube and the discharge of steam in the first steam chamber.

[0023] Preferably, a perforated plate one is provided between the separation mechanism and the transfer mechanism, and a perforated plate two is provided between the pressure relief mechanism and the transfer mechanism;

[0024] The transfer mechanism has several core tubes, and the two ends of the core tubes are connected to the holes of the first perforated plate and the holes of the second perforated plate, respectively.

[0025] The number of holes in the perforated plate one and perforated plate two is the same as the number of core tubes, which can effectively disperse steam, avoid steam impact, and enable the steam from the previous stage to better act on the steam from the next stage during actual steam transfer, thereby improving steam quality.

[0026] Preferably, the separation mechanism is provided with a first partition plate, and the pressure relief mechanism is provided with a second partition plate;

[0027] A rotating shaft passing through the transfer mechanism is connected between the first and second partition plates, so that the separation mechanism and the pressure relief mechanism rotate synchronously relative to the transfer mechanism.

[0028] After connecting partition plate one and partition plate two, they can rotate synchronously, thereby achieving better steam discharge.

[0029] Preferably, the low-pressure medium chamber is connected to a negative pressure device.

[0030] The negative pressure device can attract the piston to move, so that the piston is positioned close to the pressure relief mechanism, thereby allowing the high-pressure medium to better push the piston, so that the steam in the core tube can enter the first steam chamber.

[0031] Preferably, the conversion device operates intermittently to receive steam at different temperatures and / or pressures in the first steam chamber.

[0032] Intermittent operation can effectively collect steam of different qualities, thereby better meeting different energy recovery needs.

[0033] Preferably, the conversion device operates continuously to receive steam at the same temperature and / or pressure, or steam at a similar temperature and / or pressure, in the first steam chamber.

[0034] Continuous operation enables consistent, high-quality collection, achieves more efficient conversion and utilization, and meets better energy recovery and utilization needs.

[0035] Compared with existing technologies, this invention can realize the step-by-step recovery and reuse of steam to obtain steam of different quality grades. On this basis, it can obtain higher quality grades of steam by step-by-step pressurization of steam to better meet actual use needs. Attached Figure Description

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0042] like Figures 1-4As shown, a hot water steam conversion device includes a separation mechanism 100, a pressure relief mechanism 200, and a transfer mechanism 300. The separation mechanism 100 includes a first steam chamber 1, a separation chamber 2, and a second steam chamber 3. The separation chamber 2 is used to introduce high-temperature water, and the steam generated by the high-temperature water enters the second steam chamber 3. The pressure relief mechanism 200 is provided with a high-pressure medium chamber 4 for introducing a high-pressure medium and a low-pressure medium chamber 5 for discharging a low-temperature medium. The transfer mechanism 300 is provided with a core tube 6, and a piston is movably disposed inside the core tube 6. The separation mechanism 100 and the pressure relief mechanism 200 can rotate relative to the transfer mechanism 300, or the transfer mechanism 300 can rotate relative to the separation mechanism 100 and the pressure relief mechanism 200. During rotation, the core tube 6 switches between the first steam chamber 1 and the second steam chamber 3, and between the high-pressure medium chamber 4 and the low-pressure medium chamber 5.

[0043] In this embodiment, when high-temperature water enters the separation chamber 2, it evaporates to form steam. The steam enters the second steam chamber 3 and then enters the core tube 6, pushing the piston closer to the pressure relief mechanism 200. The high-temperature water cools down after evaporation and flows out of the separation chamber 2. Simultaneously, the separation mechanism 100 and the pressure relief mechanism 200 rotate. At this time, the core tube 6, which stores steam, corresponds to the first steam chamber 1 and also to the high-pressure medium chamber 4. Therefore, by introducing a high-temperature medium into the high-pressure medium chamber 4, the high-temperature medium pushes the piston towards the separation mechanism 100, causing the piston to push the steam in the core tube 6 into the first steam chamber 1, thus allowing the steam to enter the pre-configured gas storage tank. Afterward, by rotating the separation mechanism 100 and the pressure relief mechanism 200 again, the high-temperature medium entering the core tube 6 cools down and enters the low-pressure medium chamber 5, thus being discharged from the low-pressure medium chamber 5. During continued rotation, waste heat recovery can be achieved through the above process.

[0044] It should be noted that, in this embodiment, the outer side of the separation mechanism 100, the pressure relief mechanism 200 and the transfer mechanism 300 is provided with a housing 7 to form a receiving space for the separation mechanism 100 and the pressure relief mechanism 200, and to achieve appearance protection for the entire device.

[0045] Furthermore, the separation mechanism 100 is divided into multiple chambers in a circumferential direction, one of which is a first steam chamber 1, and the other chambers are divided into a separation chamber 2 and a second steam chamber 3. A steam conduit 8 is provided between the separation chamber 2 and the second steam chamber 3 in the same chamber, and a water pipe 9 is connected between any adjacent separation chambers 2. The first steam chamber 1 is provided with an exhaust port 10. One of the separation chambers 2 adjacent to the first steam chamber 1 is provided with a high-temperature water inlet 11, and the other separation chamber 2 adjacent to the first steam chamber 1 is provided with a low-temperature water outlet 12. In this embodiment, the first steam chamber 1 is connected to an external gas storage tank through the exhaust port 10 to realize the recovery and utilization of steam. In this embodiment, multiple chambers are provided, one of which is the first steam chamber 1, and the other chambers are divided into a separation chamber 2 and a second steam chamber 3. Thus, after some of the high-temperature water forms the highest-grade steam, the remaining high-temperature water can enter the next separation chamber 2 to form secondary steam and then enter the corresponding second steam chamber 3. That is to say, multi-stage steam recovery is achieved through a gradient method. At this time, the separation mechanism 100 and the pressure relief mechanism 200 can rotate synchronously, and with multiple gas storage tanks prepared, the collection of steam of various qualities can be realized. That is, in this embodiment, the conversion device operates intermittently to receive steam of different temperatures and / or pressures in the first steam chamber 1, so that the different gas storage tanks connected to the first steam chamber 1 can receive steam of different qualities respectively.

[0046] In another technical solution of this embodiment, the conversion device operates continuously to receive steam at the same temperature and / or pressure, or steam at a similar temperature and / or pressure, in the first steam chamber 1. In other words, this embodiment can upgrade low-quality steam to high-quality steam, thereby achieving the recovery of high-quality steam. Specifically, high-temperature water continuously flows in and out of the separation mechanism 100. Based on the above operating method, the rotation direction is always from the separation chamber 2 that generates low-quality steam to the separation chamber 2 that generates high-quality steam. Therefore, when a core tube 6 stores low-quality steam, it will move to the separation chamber 2 that generates high-quality steam as the corresponding mechanism rotates. At this time, since the separation chamber 2 that generates high-quality steam has a higher pressure and / or temperature than the low-quality steam in the core tube 6, the generated high-quality steam will pressurize the low-quality steam in the core tube 6, thereby obtaining steam of a higher quality than the low-quality steam, thus achieving the improvement of the quality level of the low-quality steam. As the corresponding mechanism continues to rotate, the steam with improved quality level will enter the first steam chamber 1 to achieve the recovery of the formed high-quality steam. Therefore, this embodiment uses multiple separation chambers 2 and a second steam chamber 3 to distribute and depressurize high-temperature water in multiple stages, obtaining steam of decreasing quality at each stage. By rotating the corresponding mechanism, the low-quality steam generated in the second steam chamber 3 is transferred stage by stage through the second steam chamber 3 that generates high-quality steam at each stage, thereby obtaining high-quality steam. Therefore, this embodiment can convert all the heat in the high-temperature water into higher-quality steam, with high conversion efficiency. It is known that currently, hot water steam conversion mainly adopts flash evaporation technology, that is, obtaining steam after depressurization and steam-water separation in a flash tank. This method has a large steam pressure loss and extremely low heat utilization efficiency. For example, to obtain 180°C steam from 200°C high-temperature hot water, only the heat in the 180-200°C range can be utilized. However, using the technical solution of this embodiment, to obtain 180°C steam, heat from 100-200°C, or even lower temperatures and a wider range, can be utilized, and the heat utilization efficiency is increased exponentially. This provides a more efficient way to utilize low-quality waste heat in industrial enterprises.

[0047] It should be noted that in this embodiment, the high-pressure medium chamber 4 has a pipe 19 and the low-pressure medium chamber 5 has a pipe 20, thereby realizing the flow of the medium.

[0048] The high-temperature medium can be high-temperature water or high-temperature gas. It is known that the pressure of the medium relative to the piston is greater than the pressure exerted on the piston by the steam.

[0049] In this embodiment, the chambers in the separation mechanism 100 are uniformly divided; the separation chamber 2 is located above the second steam chamber 3. The second steam chamber 3 is located below the separation chamber 2, meaning that the steam generated in the separation chamber 2 moves from top to bottom, enters the second steam chamber 3, and then enters the core tube 6, while the high-temperature water is relatively above. It is known that the steam conduit 8 extends above the separation chamber 2, thereby preventing high-temperature water from entering the core tube 6. Furthermore, the radial area of ​​the high-pressure medium chamber 4 and the low-pressure medium chamber 5 separated by the pressure relief mechanism 200 are equal, and equal to the radial area of ​​the chambers in the separation mechanism 100. It is known that the lower the temperature of the high-temperature water, the lower the quality of the generated steam, and the less steam is generated. Therefore, equal radial areas, based on the same structure of the chambers, can ensure that high-quality steam pressurizes low-quality steam.

[0050] To improve the efficiency of hot water steam conversion, this embodiment continuously feeds high-temperature water into the separation mechanism 100 to generate steam of different qualities. In order to ensure continuity and to ensure that the low-quality steam has a sufficient movement path to sequentially and gradually contact different high-quality steam, the high-pressure medium chamber 4 and the low-pressure medium chamber 5 are arranged adjacent to each other in this embodiment, so as to ensure that the low-quality steam is pressurized and upgraded to higher-quality steam.

[0051] In this embodiment, a perforated plate 13 is disposed between the separation mechanism 100 and the transfer mechanism 300, and a perforated plate 24 is disposed between the pressure relief mechanism 200 and the transfer mechanism 300. The transfer mechanism 300 has a plurality of core tubes 6, the two ends of which are respectively connected to the holes of the perforated plate 13 and the holes of the perforated plate 24. Core tubes are connected to the holes of both the perforated plate 13 and the perforated plate 24 to disperse and flow the steam, improving both fluidity and pressure efficiency.

[0052] In this embodiment, the separation mechanism 100 is provided with a first partition plate 15, and the pressure relief mechanism 200 is provided with a second partition plate 16. A rotating shaft passing through the transfer mechanism 300 connects the first partition plate 15 and the second partition plate 16, allowing the separation mechanism 100 and the pressure relief mechanism 200 to rotate synchronously relative to the transfer mechanism 300. Both the first partition plate 15 and the second partition plate 16 have a star-shaped divergent structure with a connecting part in the middle, thereby achieving the aforementioned synchronous movement. It should be noted that the synchronization refers to coaxiality, speed, and direction, thus avoiding the need for an additional drive mechanism and effectively reducing costs. In another technical solution of this embodiment, the separation mechanism 100 and the pressure relief mechanism 200 are stationary, and rotation is achieved by driving the transfer mechanism 300. In this case, it is generally achieved through a gear mechanism, gear chain mechanism, gear belt mechanism, etc., which will not be elaborated here.

[0053] Furthermore, it should be noted that since the separation chamber 2 and the second steam chamber 3 are vertically separated, a notched isolation plate 17 is also provided in the separation mechanism 100. The isolation plate 17 not only separates the separation chamber 2 and the second steam chamber 3 within the corresponding chambers, but also allows steam to be smoothly discharged and recovered through the gas storage tank after entering the first steam chamber 1. Similarly, the pressure relief mechanism 200 is also provided with a second isolation plate 18, which provides openings for the flow of high-temperature and low-temperature media, ensuring the fluidity of the high-temperature / low-temperature media while preventing excessive piston movement.

[0054] In this embodiment, after the steam is discharged from the first steam chamber 1, the piston needs to be moved to a position close to the pressure relief mechanism 200 so that the core tube can store a sufficient amount of steam. In this embodiment, the piston is generally driven by the lowest quality steam. At this time, the lowest quality steam is generated by cooling the water to the lowest temperature in this device. Therefore, its pressure and / or temperature are the lowest, so its thrust may not be enough to push the piston to the lowest point. Therefore, in this embodiment, a negative pressure device can be connected to the low-pressure medium chamber 5. That is, a negative pressure is formed by the negative pressure device to attract the piston to move, thereby ensuring that the low quality steam can completely enter the core tube 6. As a result, when it passes through the higher-grade second steam chamber 3, its pressurization effect is better.

[0055] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
