Description

Technical Field

[0001] This utility model relates to the field of horizontal nuclear power plant evaporator technology, and in particular to a steam-water separator for a horizontal nuclear power plant evaporator. Background Technology

[0002] A horizontal nuclear power plant steam-water separator is a device used in the steam generator of a nuclear power plant to separate the steam-water mixture and obtain dry steam. It is usually arranged horizontally to improve space utilization and optimize the separation effect.

[0003] To address the aforementioned issues, existing patents offer solutions. However, current steam-water separators lack a structure for detecting the sealing performance of the connections. The connections of horizontal nuclear power plant steam-water separators are subjected to high temperature and high pressure conditions for extended periods, while also experiencing vibrations and impacts from the flow of the steam-water mixture and erosion from the medium. This causes the sealing rubber rings to age and harden, and the annular anti-slip texture to wear, gradually deteriorating the sealing performance. Consequently, initial minor leaks of the steam-water mixture may only penetrate into the gaps in the sealing surface without forming obvious overflows. Maintenance personnel cannot detect this through routine inspections. Only when the leakage accumulates to a certain level will visible dripping or splashing occur, thus missing the optimal repair time.

[0004] Therefore, a horizontal nuclear power plant evaporator steam-water separator is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a horizontal nuclear power plant evaporator steam-water separator, which solves the problem that existing horizontal nuclear power plant evaporators lack a structure for detecting the sealing performance of the connection. The connection of the horizontal nuclear power plant evaporator steam-water separator is under high temperature and high pressure conditions for a long time, and is also subjected to vibration and impact from the flow of steam-water mixture and media erosion. The sealing rubber ring is prone to aging and hardening, and the annular anti-slip texture wears down, which gradually deteriorates the sealing performance. As a result, the initial small amount of steam-water mixture leakage may only seep into the gap of the sealing surface without forming an obvious overflow. Maintenance personnel cannot detect it through routine inspections. When the leakage accumulates to a certain level, visible dripping or splashing will appear, thus missing the best maintenance time.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The connection mechanism of this application adopts a connecting rod that passes through the fixing hole of the connecting plate and the connecting flange. With the help of the fixing nut, the connecting sleeve can be fixed on the right side of the steam-water separator body and the left side of the external connecting pipe.

The PLC controller is linked with the buzzer alarm and the electromagnetic drain valve. When the gas detection sensors and liquid detection sensors detect that the medium has entered the storage square tube, the PLC controller can immediately trigger the buzzer alarm to issue a warning signal, reminding maintenance personnel to intervene in time. At the same time, it can control the electromagnetic drain valve to open, and discharge the accumulated liquid or impurities in the storage square tube through the drain pipe.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A horizontal nuclear power plant evaporator steam separator includes a steam separator body 1. A connecting mechanism 2 is welded to the right side surface of the steam separator body 1. A detection mechanism 3 is installed inside the connecting mechanism 2. The detection mechanism 3 includes a connecting pipe 31, a storage square tube 32, a gas detection sensor 33, a liquid detection sensor 34, a mounting plate 35, a PLC controller 36, a fixing rod 37, and a buzzer alarm 38. The connecting pipe 31 is fixedly connected to the bottom of the connecting mechanism 2, and the top of the connecting pipe 31 extends through and into the inside of the connecting mechanism 2. The storage square tube 32 is fixedly connected to the bottom of the connecting pipe 31. The gas detection sensor 33 is installed on the top right side of the storage square tube 32, and the liquid detection sensor 34 is installed on the bottom right side of the storage square tube 32. The detection ends on the left side of the gas detection sensor 33 and the liquid detection sensor 34 both extend through and into the inside of the storage square tube 32.

[0029] In this embodiment: the steam-water separator body 1 is made of high-strength metal material welded together, which can stably withstand the high temperature and high pressure of the nuclear power plant's secondary loop, avoiding deformation or cracking of the body due to operating stress. This provides a stable installation and working environment for internal steam-water separation units such as the vortex separator and corrugated plate dryer. At the same time, it supports and limits the connection mechanism 2. When a leak occurs at the connection between the steam-water separator body 1 and the external pipeline, the connecting pipe 31 can guide the leaked medium to the inside of the storage square tube 32. The storage square tube 32 serves as a temporary storage and detection carrier for the medium, and can temporarily retain the medium transported by the connecting pipe 31. The gas detection sensor 33 can detect in real time whether there is gas in the storage square tube 32. The gas and liquid detection sensor 34 can detect whether there is liquid in the storage square tube 32 in real time. The mounting plate 35 can support and limit the PLC controller 36. The PLC controller 36 can receive the detection data of the gas detection sensor 33 and the liquid detection sensor 34 in real time, and control the buzzer alarm 38 and the electromagnetic drain valve 7. The fixing rod 37 can support and limit the buzzer alarm 38. The buzzer alarm 38 is linked with the PLC controller 36. When the gas detection sensor 33 or the liquid detection sensor 34 detects liquid or gas in the storage square tube 32, it can respond quickly and issue a clear warning signal through a high-decibel buzzer sound, solving the problem of lag in traditional equipment relying on manual inspection.

[0030] Specifically, such as Figure 2 , Figure 3 As shown, the mounting plate 35 is welded to the left side of the storage square tube 32, the PLC controller 36 is mounted on the front side of the mounting plate 35, the fixing rod 37 is welded to the surface of the connecting mechanism 2, and the buzzer alarm 38 is mounted on the top of the fixing rod 37.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the connecting mechanism 2 includes a connecting plate 21, a connecting sleeve 22, a snap-fit ​​groove 23, a sealing rubber ring 24, a connecting flange 25, several fixing holes 26, a connecting rod 27, and a fixing nut 28. The connecting plate 21 is welded to the surface of the right side of the steam-water separator body 1.

[0032] Specifically, such as Figure 4 , Figure 5 As shown, the connecting sleeve 22 is movably connected to the right side surface of the steam-water separator body 1. The snap-fit ​​groove 23 is opened inside the connecting sleeve 22. The sealing rubber ring 24 is installed inside the snap-fit ​​groove 23. The connecting pipe 31 is fixedly connected to the bottom of the connecting sleeve 22. The top of the connecting pipe 31 passes through the connecting sleeve 22 and the sealing rubber ring 24 respectively and extends to the inside of the sealing rubber ring 24. The connecting flange 25 is welded to the left side and the right side of the connecting sleeve 22 respectively.

[0033] In this embodiment: the connecting plate 21 can limit the connecting sleeve 22. The left side of the inner side of the connecting sleeve 22 connects to the connecting pipe 31 on the right side of the steam-water separator body 1, and the right side of the inner side connects to the external conveying connecting pipe 31. Simultaneously, it can support and limit the snap-fit ​​groove 23, which can also support and limit the sealing rubber ring 24. The sealing rubber ring 24 can seal the connection between the connecting pipe 31 on the right side of the steam-water separator body 1 and the external connecting pipe 31. The left side connecting flange 25 connects to the connecting plate 2. 1. To achieve the fixation of the mechanism, the right-side connecting flange 25 is used to connect to the external pipeline. The fixing hole 26 can limit the connecting rod 27. The connecting rod 27 passes through the fixing hole 26 of the connecting plate 21 and the connecting flange 25, so that the connecting sleeve 22 can be fixed on the right side surface of the steam-water separator body 1. The fixing nut 28 connects the connecting plate 21 and the connecting flange 25 through the thread preload and has good disassembly. When it is necessary to replace the seal or repair the connecting mechanism 2, the components can be separated by removing the nut, reducing the difficulty of operation and maintenance.

[0034] Specifically, such as Figure 4 , Figure 5 As shown, fixing holes 26 are respectively opened on the surface of the connecting plate 21 and the surface of the connecting flange 25. The connecting rod 27 is movably connected to the inside of the fixing hole 26. The left side of the connecting rod 27 passes through and extends to the outer side of the left side of the connecting plate 21, and the right side of the connecting rod 27 passes through and extends to the outer side of the right side of the right connecting flange 25. The fixing nut 28 is threadedly connected to the left side of the connecting rod 27.

[0035] Specifically, such as Figure 3 As shown, a sealing ring 4 is welded to the side of the connecting pipe 31 near the storage square pipe 32, and the surface of the sealing ring 4 is coated with an anti-corrosion coating.

[0036] In this embodiment: by setting a sealing ring 4, leakage of the steam and water medium from the connection is prevented; by setting an anti-corrosion coating, the erosion of the high-temperature and high-pressure steam and water medium can be resisted, and the aging and failure of the sealing ring 4 can be delayed.

[0037] Specifically, such as Figure 4 As shown, an anti-slip pad 5 is slidably connected to the surface of the right side of the connecting rod 27, and the left side of the anti-slip pad 5 is in contact with the surface of the right side connecting flange 25.

[0038] Specifically, such as Figure 4 As shown, a drain pipe 6 is fixedly connected to the bottom of the storage square tube 32, and an electromagnetic drain valve 7 is installed on the surface of the drain pipe 6.

[0039] In this embodiment: by setting anti-slip pads 5, the pre-tightening force of the external nut thread connection can be enhanced when the right connecting flange 25 is connected to the external connecting pipe 31. By setting drain pipe 6, the condensate, gas or impurities accumulated in the storage square pipe 32 can be discharged. By setting electromagnetic drain valve 7, and through the linkage control of PLC controller 36, draining can be achieved on demand based on sensor monitoring data.

[0040] Specifically, such as Figure 1 As shown, support bases 8 are welded to both sides of the bottom of the steam water dispenser body 1, and mounting holes 9 are opened on both sides of the bottom of the support base 8.

[0041] Specifically, such as Figure 6 As shown, several heat dissipation fins 10 are welded to the rear side of the mounting plate 35. The front side of the heat dissipation fins 10 penetrates the mounting plate 35 and contacts the rear surface of the PLC controller 36. The side of the heat dissipation fins 10 closest to the PLC controller 36 is coated with a thermally conductive coating.

[0042] In this embodiment: by setting a support base 8, the contact area between the steam-water separator body 1 and the mounting surface is increased, reducing the unit pressure of the steam-water separator body 1 on the mounting surface; by setting mounting holes 9, mounting channels are provided for fasteners such as anchor bolts, allowing the steam-water separator body 1 to be firmly fixed to the mounting base; by setting heat dissipation fins 10, the heat dissipation area is increased, which can quickly conduct the heat generated by the PLC controller 36 during operation, avoiding circuit failures caused by high-temperature environments; by setting thermal conductive coating, the heat conduction efficiency is improved, ensuring that the controller temperature is maintained within a safe range.

[0043] Working principle: First, the operator fixes the steam-water dispenser body 1 to the mounting surface by inserting anchor bolts through the mounting holes 9. Then, the operator movably fits the connecting sleeve 22 onto the right side surface of the body, and the sealing rubber ring 24 is embedded in the snap-fit ​​groove 23 inside the connecting sleeve 22. Next, the operator aligns the connecting flange 25 on the left side of the connecting sleeve 22 with the connecting plate 21, and inserts the connecting rod 27 through the fixing holes 26 on the surfaces of the connecting plate 21 and the connecting flange 25. The operator then tightens the fixing nut 28 on the left side of the connecting rod 27, using the thread preload to tightly fix the connecting plate 21 and the connecting flange 25, completing the assembly of the connecting mechanism 2 and the body. The right connecting flange 25 is reserved for a connection interface with an external pipeline. After the connecting mechanism 2 is assembled, the external delivery pipe is then... The connecting flange 25 on the right side of the connecting sleeve 22 is fixed in place. At this time, a sealed connection channel is formed inside the connecting sleeve 22, connecting the right interface of the steam-water separator body 1, the sealing rubber ring 24, and the external pipe interface. The sealing rubber ring 24 in the snap-fit ​​groove 23 is squeezed and deformed, tightly fitting the right surface of the body and the external pipe interface, forming an annular sealing surface, preventing the high-temperature and high-pressure steam-water mixture from leaking from the connection. At the same time, the connecting pipe 31 of the detection mechanism 3 has been pre-fixed to the bottom of the connecting sleeve 22, and its top passes through the connecting sleeve 22 and the sealing rubber ring 24 and extends to the inside of the sealed connection channel, forming a closed medium flow channel for the steam-water separator body 1, the connecting mechanism 2, and the external pipe. At the same time, a dedicated acquisition channel is constructed for subsequent medium leakage monitoring. Subsequently, during equipment operation, the gas-liquid mixture is separated inside the gas-liquid separator body 1. The high-temperature, high-pressure medium flows within the sealed channel of the connecting mechanism 2. At this time, the detection mechanism 3 enters real-time monitoring mode. The connecting pipe 31 serves as the medium acquisition channel. If a slight leak occurs at the sealed connection of the connecting mechanism 2, the leaked gas-liquid medium will be guided through the connecting pipe 31 to the storage square tube 32. The storage square tube 32 briefly retains the medium to prevent excessively fast flow rates from causing detection distortion. The gas detection sensor 33 and the liquid detection sensor 34 work synchronously, respectively capturing the presence of leaking gas or liquid in the tube in real time and transmitting the detection data to the PLC controller 36 in real time. Finally, the PLC controller 36 receives the sensor data and proceeds... Real-time analysis is performed. When gas or liquid is detected inside the storage square tube 32, a control signal is sent to the buzzer alarm 38. The buzzer alarm 38 responds quickly and emits a high-decibel buzzing sound, promptly conveying a leak warning signal to maintenance personnel, thus solving the problem of lag in traditional manual inspections. Simultaneously, the PLC controller 36 can control the electromagnetic drain valve 7 on the drain pipe 6 at the bottom of the storage square tube 32. Based on the monitoring data from the gas detection sensor 33 and the liquid detection sensor 34, the valve opens as needed. After the electromagnetic drain valve 7 opens, the accumulated liquid, impurities, or leaked media in the storage square tube 32 are discharged through the drain pipe 6, preventing media accumulation from affecting sensor detection accuracy or exacerbating equipment corrosion. After drainage is completed, the valve closes. If maintenance of the connecting mechanism 2 is required...The fixing nut 28 on the detachable connecting rod 27 can be used to separate the connecting plate 21 from the connecting flange 25, and easily worn parts such as the sealing rubber ring 24 can be replaced.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
