Description

Technical Field

[0001] The utility model relates to the technical field of steam compressors, in particular to a spraying device and a steam compressor. Background Art

[0002] In the internal structure of a steam compressor, a spraying system is usually designed. The core purpose of this system is to improve the operating efficiency of the compressor in multiple aspects. Specifically, regarding the composition of the spraying system, its core components are spray heads, which are precisely installed inside the compressor and spray water mist into the steam compressor through precise regulation. However, during actual operation, the water mist sprayed by the spray heads often contains a large number of tiny water droplets. Under the pushing action of the secondary steam, these water droplets will inevitably impact the high-speed rotating impeller. It should be noted that when the steam compressor is in normal operation, the rotational speed of the impeller is usually as high as tens of thousands of revolutions per minute or even higher. Facing the continuous impact of tiny water droplets, the surface of the impeller is extremely vulnerable to damage. This physical impact will not only cause increased wear of the impeller but also may lead to vibration and noise problems. In severe cases, it may even pose a threat to the stable operation of the entire compressor, thereby affecting the normal operation and production efficiency of the steam compressor. Summary of the Utility Model

[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the related technologies. The utility model provides a spraying device and a steam compressor.

[0004] The utility model provides the following technical solutions:

[0005] A spraying device for spraying the interior of a steam compressor, comprising a spraying pipeline, spray heads, and a water delivery pipe.

[0006] The spraying pipeline is vertically arranged, and the lower end of the spraying pipeline is communicated with the outlet of the steam compressor; the spray heads are arranged inside the spraying pipeline; the water delivery pipe penetrates through the side wall of the spraying pipeline, one end of the water delivery pipe is communicated with the spray head, and the other end of the water delivery pipe is connected to a water delivery device.

[0007] As a further improvement of the above technical solution, the spray head is located above the impeller of the steam compressor.

[0008] As a further improvement of the above technical solution, the spray head is arranged to spray in a direction that does not directly shoot at the impeller.

[0009] As a further improvement of the above technical solution, the spraying direction of the spray head is vertically upward.

[0010] As a further improvement of the above technical solution, at least two spray heads are evenly distributed in the spray pipeline.

[0011] As a further improvement of the above technical solution, the installation heights of the multiple spray heads are the same.

[0012] As a further improvement of the above technical solution, the spray head is a medium-pressure micro-fine atomization spray head.

[0013] As a further improvement of the above technical solution, the spray device further includes a control module, and the control module is electrically connected to the drive motor of the steam compressor and the water conveyance device respectively.

[0014] As a further improvement of the above technical solution, the diameter of the spray pipeline is larger than the outlet diameter of the steam compressor, and the lower end of the spray pipeline is communicated with the outlet of the steam compressor through a conical pipe.

[0015] The present utility model further provides a steam compressor, including the spray device as described in any one of the above.

[0016] Compared with the related art, the beneficial effects of the present utility model are:

[0017] The spray device provided by the present utility model plays a crucial role during the operation of the steam compressor. Specifically, when the steam compressor starts to work, the impeller inside it rotates at an extremely high speed. At this time, steam is inhaled from the inlet of the steam compressor, enters the inside of the steam compressor for compression treatment, and then is discharged from the outlet of the steam compressor. These compressed steam will continue to flow along the spray pipeline connected to the outlet and enter the next treatment process.

[0018] At the same time, during the entire operation of the steam compressor, the water conveyance device will also be started synchronously. The water conveyance device continuously conveys water to the spray heads in the spray pipeline through the water conveyance pipe. These water flows will form water mist after being specially treated by the spray heads and be sprayed inside the steam compressor. This spraying process can effectively cool the inside of the steam compressor and prevent it from malfunctioning or being damaged due to excessive temperature.

[0019] It should be noted that, among the water mist ejected from the spray head, although most of it can form a delicate atomization effect, it is inevitable that some small water droplets are not completely atomized. However, these incompletely atomized small water droplets will not have a negative impact on the steam compressor. Because when they exist, they will be carried away by the steam flow discharged from the outlet, thus preventing the small water droplets from falling on the impeller inside the steam compressor and causing unnecessary impact and damage to the impeller. In this way, the spray device provided by the present utility model can not only effectively reduce the probability of impeller damage, but also significantly extend the service life of the impeller.

[0030] Embodiment 1

[0031] As Figure 1 shown, this embodiment provides a spraying device for spraying the interior of a steam compressor 100, including a spraying pipeline 200, a spraying head 300, and a water delivery pipe 400.

[0032] The spray pipe 200 is vertically arranged, and the lower end of the spray pipe 200 is communicated with the outlet 120 of the steam compressor 100; the spray head 300 is arranged in the spray pipe 200; the water delivery pipe 400 penetrates through the side wall of the spray pipe 200, one end of the water delivery pipe 400 is communicated with the spray head 300, and the other end of the water delivery pipe 400 is connected with a water delivery device.

[0033] The spray device provided in this embodiment plays a crucial role during the operation of the steam compressor 100. Specifically, when the steam compressor 100 starts to work, the impeller inside it rotates at an extremely high speed. At this time, steam is inhaled from the inlet 110 of the steam compressor 100, enters the inside of the steam compressor 100 for compression treatment, and then is discharged from the outlet 120 of the steam compressor 100. These compressed steam will continue to flow along the spray pipe 200 connected to the outlet 120 and enter the next treatment process. At the same time, during the entire operation of the steam compressor 100, the water delivery device will also be started synchronously. The water delivery device continuously delivers water flow to the spray head 300 in the spray pipe 200 through the water delivery pipe 400. After passing through the special treatment of the spray head 300, these water flows will form water mist and be sprayed inside the steam compressor 100. This spraying process can effectively cool the inside of the steam compressor 100 and prevent it from malfunctioning or being damaged due to excessive temperature.

[0034] It should be noted that although most of the water mist ejected from the spray head 300 can form a delicate atomization effect, it is inevitable that some small water droplets are not completely atomized. However, these incompletely atomized small water droplets will not have a negative impact on the steam compressor 100. Because when they exist, they will be carried away by the steam flow discharged from the outlet 120, thus avoiding the small water droplets from falling on the impeller inside the steam compressor 100 and causing unnecessary impact and damage to the impeller.

[0035] In some specific embodiments, the spray head 300 is located above the impeller of the steam compressor 100; this layout is carefully considered because only when the spray head 300 is located above, the water mist ejected by it can fall on the rotating impeller in the most natural and stable way under the action of gravity. In this way, the water mist can fully cover every part of the impeller and achieve a uniform and effective cooling effect.

[0036] More importantly, such a design also fully takes into account various complex factors that may occur during the operation of the steam compressor 100. For example, the high-temperature and high-pressure environment inside the steam compressor 100, the rapid rotation of the impeller, and the dynamic changes in the steam flow may all affect the effect of spray cooling. However, by placing the spray head 300 above the impeller, we can minimize the influence of these factors to ensure that the water mist can stably and accurately fall on the impeller, thereby achieving continuous and effective cooling of the impeller.

[0037] In some specific embodiments, the spray head 300 is arranged to spray in a direction that does not directly irradiate the impeller; by adjusting the spray direction of the spray head 300 to a direction that does not directly irradiate the impeller, in this way, the small water droplets with incomplete atomization will not directly fall on the impeller, but will further atomize in the space inside the steam compressor 100 or be carried away by the steam flow discharged from the outlet 120. This can not only ensure the effective cooling of the inside of the steam compressor 100 by the water mist but also avoid potential damage to the impeller.

[0038] In some specific embodiments, the spray direction of the spray head 300 is vertically upward; the original intention of this design is to further avoid the direct spraying of the spray head 300 on the impeller, thereby minimizing the possible damage to the impeller.

[0039] In actual operation, the vertically upward spray direction means that the water mist will form an effect similar to a "rain curtain" inside the steam compressor 100, rather than directly impacting the rotating surface of the impeller. Such a design can not only effectively avoid the direct falling of the small water droplets with incomplete atomization on the impeller, causing impact and wear, but also ensure that the water mist can be more evenly distributed in the internal space of the steam compressor 100, achieving a more efficient cooling effect.

[0040] In addition, the vertically upward spray direction helps to reduce the direct interaction between the spray head 300 and the impeller, reducing the additional vibration and noise generated by spraying, thereby further improving the operating stability and reliability of the steam compressor 100.

[0041] In some specific embodiments, at least two spray heads 300 are evenly distributed in the spray pipe 200; by evenly distributing at least two spray heads 300 in the spray pipe 200, it can ensure that the water mist can be evenly sprayed inside the steam compressor 100, achieving full coverage and effective cooling of the high-temperature area. This layout method not only improves the cooling efficiency but also avoids equipment failures or performance degradation caused by local overheating.

[0042] In some specific embodiments, the installation heights of the plurality of spray heads 300 are the same; First of all, keeping the installation heights of the plurality of spray heads 300 the same can significantly improve the uniformity of spraying inside the steam compressor 100. Since the spatial structure and temperature distribution inside the steam compressor 100 are often relatively complex, if the installation heights of the spray heads 300 are inconsistent, it may lead to deviations in the spraying effect of the water mist, with some areas receiving excessive spraying while other areas receiving insufficient spraying. By unifying the installation heights of all the spray heads 300, we can ensure that the water mist can evenly cover the entire inside of the steam compressor 100, thereby achieving effective cooling of the high-temperature areas.

[0043] Secondly, this design also helps to improve the working efficiency and stability of the spray heads 300. Since the heights of the spray heads 300 are the same, the pressure and resistance they receive will be relatively balanced, which helps to reduce equipment vibration and noise caused by uneven spraying. At the same time, keeping the heights of the spray heads 300 the same also facilitates their maintenance and replacement, reducing the complexity and cost of equipment maintenance.

[0044] In some specific embodiments, the plurality of spray heads 300 are all installed on the same water delivery pipe 400; First of all, concentrating the installation of the plurality of spray heads 300 on the same water delivery pipe 400 can greatly simplify the layout of the water delivery pipe 400 route. Compared with decentralized installation, this method reduces the number of pipe branches and joints, reducing the potential leakage risk caused by complex pipelines. At the same time, the centralized pipeline layout is also convenient for subsequent inspection and maintenance work. Maintenance personnel can locate and handle problems more quickly, reducing production losses caused by shutdown for maintenance.

[0045] Secondly, this design also helps to improve the overall stability and reliability of the spray system. Since all the spray heads 300 are connected to the same water delivery pipe 400, they can share the same water source and pressure, thus ensuring the uniformity and consistency of the spraying effect. In addition, the centralized water delivery pipe 400 route is also convenient for pressure testing and adjustment to ensure that the spray system can operate stably under various working conditions.

[0046] Finally, from an economic perspective, installing the plurality of spray heads 300 on the same water delivery pipe 400 can also reduce material costs and installation costs. Compared with the multiple pipelines and joints required for decentralized installation, the centralized installation method requires less materials and installation work, thus reducing the overall cost.

[0047] In summary, installing the plurality of spray heads 300 on the same water delivery pipe 400 not only simplifies the layout of the water delivery pipe 400 route, improves the stability and reliability of the spray system, but also reduces material costs and installation costs, providing great convenience for subsequent inspection and maintenance work.

[0048] In some specific embodiments, the spray head 300 is a medium-pressure fine atomization spray head 300; the medium-pressure fine atomization spray head 300 has unique spray effects and performance advantages. This spray head 300 can atomize water into extremely fine droplets under medium-pressure conditions. The particle size of these droplets is usually in the micron range, so they have a very high surface area and evaporation rate. When these fine droplets are sprayed into the steam compressor 100, they can quickly absorb and carry away a large amount of heat, thus achieving an efficient cooling effect.

[0049] In addition, the medium-pressure fine atomization spray heads 300 also have excellent stability and durability. They can maintain a stable spray effect and atomization performance under long-term continuous working conditions, and are not prone to problems such as clogging or wear. This is crucial for ensuring the continuity and stability of the cooling inside the steam compressor 100.

[0050] More importantly, the medium-pressure fine atomization spray heads 300 also have good energy-saving effects. Due to their fine droplets and high evaporation rate, relatively less water is required, thus reducing energy consumption and operating costs.

[0051] In some more detailed and specific embodiments, the spray device not only includes the spray head 300 and water delivery equipment for generating and transporting water mist, but also particularly adds a control module. This control module plays a crucial role in the entire spray system. It realizes precise control and synchronous coordination of these two key components by establishing electrical connections with the drive motor of the steam compressor 100 and the water delivery equipment.

[0052] The control module is first connected to the drive motor of the steam compressor 100 and can obtain the operating status and parameters of the drive motor in real time, such as rotational speed, power, etc. By analyzing and processing these data, the control module can accurately judge the working status of the steam compressor 100, and then start or adjust the working status of the water delivery equipment in a timely manner according to the preset cooling strategy. This design ensures that the steam compressor 100 can be efficiently operated while being timely and appropriately sprayed with water mist, thereby effectively reducing its internal temperature and improving the stability and reliability of the equipment.

[0053] At the same time, the electrical connection between the control module and the water delivery equipment also provides precise flow and pressure control for it. According to the actual needs of the steam compressor 100, the control module can flexibly adjust the output flow and pressure of the water delivery equipment to ensure that the water mist can be evenly and stably sprayed inside the steam compressor 100, achieving precise control of the cooling effect.

[0054] In addition, the control module also has functions of fault detection and alarm. Once a fault or abnormal situation occurs in the steam compressor 100 or the water conveyance device, the control module can respond quickly, send out an alarm signal, and take corresponding protection measures to prevent the fault from expanding further and ensure the safe operation of the entire spray system.

[0055] In some specific embodiments, the diameter of the spray pipeline 200 is larger than the diameter of the outlet 120 of the steam compressor 100, which is convenient for providing a larger space for the spraying of the spray head 300; the lower end of the spray pipeline 200 is connected to the outlet 120 of the steam compressor 100 through a tapered pipe 500, which is convenient for supporting installation.
