Description

Technical Field

[0001] The invention relates to the technical field of steam sampling equipment, in particular to an intelligent boiler steam-water sampling device. Background Art

[0002] Boiler water sampling devices are essential, critical equipment in boiler systems, primarily used to collect boiler water and steam samples for chemical analysis and monitoring. During boiler operation, the quality of the water directly impacts the safety, efficiency, and lifespan of the boiler. Excessive levels of impurities, dissolved oxygen, salt, or other harmful substances in boiler water and steam can lead to internal scaling, corrosion, degraded steam quality, and even, in severe cases, safety incidents such as pipe bursts. Therefore, regular sampling and analysis of boiler water and steam is crucial to ensuring safe, stable, and efficient boiler operation.

[0036] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] The present invention provides an efficient, accurate and environmentally friendly steam sample collection device by optimizing the condensation system, introducing a cooling water circulation mechanism and automatic control technology. Specific embodiments are as follows.

[0038] Example

[0039] like Figures 1-8 As shown, a boiler steam-water intelligent sampling device includes a condensing mechanism 2, characterized in that the condensing mechanism 2 includes a vent pipe 21, one end of the vent pipe 21 is connected to the boiler, and the end of the vent pipe 21 away from the boiler is fixedly connected to a condensing pipe 22, and a spring circulation pipe 23 is nested outside the condensing pipe 22, one end of the spring circulation pipe 23 is connected to the upper end of the condensing pipe 22 through a water inlet 211, and the other end of the spring circulation pipe 23 extends to the lower end of the condensing pipe 22 and is fixedly connected to an external water pipe 24;

[0040] The ventilation pipe 21 and the condensation pipe 22 are both arc-shaped pipes, and the two form a semicircular pipe;

[0041] Among them, a ball 25 is rotatably provided at the lower end of the condenser tube 22, and a return spring 26 is provided above the ball 25. The lower end of the return spring 26 abuts against the ball 25, and the upper end of the return spring 26 is fixedly connected to the tube wall of the condenser tube 22. The upper end of the ball 25 is fixedly connected to a cable 27, which extends upward along the condenser tube 22 and is fixedly connected to a blocking ring 28. The blocking ring 28 and the opening 29 coincide with each other. The blocking ring 28 and the upper end of the condenser tube 22 are fixedly connected by a support spring 210, and the blocking ring 28 is provided with an opening 29.

[0042] The middle part of the cable 27 is guided by a fixing member, and the cable 27 is divided into three groups near the end of the blocking ring 28. The three groups of cables 27 are distributed in a circular manner and fixedly connected to one end of the blocking ring 28. One end of the blocking ring 28 is pulled by three cables 27, which has high stability.

[0043] When the sealing ring 28 moves to a set distance in the condenser tube 22 , the opening 29 and the water inlet 211 overlap and connect; after the opening 29 and the water inlet 211 overlap, the water in the spring circulation tube 23 will enter the condenser tube 22 .

[0044] In this embodiment, by controlling the rotation of motor 32, turntable 31 is driven to position sampling tube 35 directly below the lower end of condenser 22. Subsequently, flow valve 14 is opened, allowing steam to enter condenser 22 via vent pipe 21. Because cooling water flows through spring-loaded circulation pipe 23 nested outside condenser 22, the ambient temperature inside condenser 22 is relatively low. Upon entering, the steam rapidly liquefies, forming water droplets that flow along the inner wall of condenser 22 and into sampling tube 35.

[0045] During the condensation process, the cooling water in the spring circulation tube 23 absorbs heat and its temperature rises, causing its density to decrease and flow upward, causing the higher-temperature cooling water to accumulate at the upper end of the spring circulation tube 23. This phenomenon ensures a high ambient temperature at the connection between the vent tube 21 and the condenser tube 22, preventing the steam from liquefying prematurely before entering the condenser tube 22, thereby preventing sample backflow and improving the collection efficiency of the steam-liquefied sample.

[0046] After the sample collection is completed, the flow valve 14 is closed, and the motor 32 is controlled to rotate so that the turntable 31 moves the drain pipe 41 to just below the lower end of the condenser 22. At this time, the ball 25 contacts the sponge 42, and the ball 25 shrinks toward the inside of the condenser 22, while compressing the reset spring 26, causing the cable 27 to relax. Without the tension of the cable 27, the sealing ring 28 is driven to slide by the contraction of the support spring 210 (the initial state of the support spring 210 is extended), and finally the opening 29 on the sealing ring 28 is aligned with the water inlet 211, and the cooling water in the spring circulation tube 23 enters the condenser 22 (the cooling water of the spring circulation tube 23 is injected by the external water pipe 24. During this process, the external water pipe 24 will inject a preset volume of water to discharge the original cooling water into the condenser 22).

[0047] During this process, the lower end of condenser tube 22 is in close contact with sponge 42 and drain pipe 41. Once the cooling water enters condenser tube 22, it cannot drain directly (sponge 42 slows the outflow of water). Consequently, it accumulates within condenser tube 22 (the cooling water accumulates after entering condenser tube 22 and then slowly drains through sponge 42). This cleans the inner wall of condenser tube 22, preventing residue from the previous sampling from being mixed into the next sample, thus ensuring sample accuracy. Furthermore, because the cooling water absorbs heat during the steam liquefaction process, the condensed water temperature at this point is higher, further enhancing the cleaning effect.

[0048] After cleaning and draining, motor 33 drives turntable 31 to rotate again, moving the next sampling tube 35 to the position directly below the lower end of condenser tube 22, ready for the next sampling. During this process, ball 25 is no longer squeezed by sponge 42, and return spring 26 is stretched, causing ball 25 to return downward. The cable 27 pulls sealing ring 28 to move, causing support spring 210 to re-extend, causing opening 29 to shift with water inlet 211, thereby sealing water inlet 211.

[0049] like Figure 1-Figure 3 As shown, the condensing mechanism 2 is connected to the boiler via a connecting mechanism 1. The connecting mechanism 1 includes an air guide pipe 17. The air guide pipe 17 is fixedly connected to the vent pipe 21. A flow valve 14 is provided on the air guide pipe 17. The flow valve 14 controls the amount of steam entering and the circulation time.

[0050] A pressure plate 13 is fixedly connected to the air guide tube 17 , a sealing gasket 12 is fixedly connected to the lower end of the pressure plate 13 , and a thread 11 is provided at the lower end of the air guide tube 17 .

[0051] In this embodiment, an air duct 17 with threads 11 is connected to a pre-set screw hole. As air duct 17 rotates, its sealing gasket 12 and pressure plate 13 gradually approach the boiler surface. Eventually, sealing gasket 12 contacts the boiler surface, forming a seal under the pressure of pressure plate 13. To take a sample, flow valve 14 is first opened to adjust the steam flow rate. Steam from the boiler, under pressure, flows through air duct 17 and into vent pipe 21.

[0052] As shown in the figure, a rotating mechanism 3 is provided below the condenser tube 22. The rotating mechanism 3 includes a turntable 31. The turntable 31 is located below the condenser tube 22. A plurality of fixed grooves 34 are distributed circumferentially on the turntable 31. A sampling tube 35 is engaged in each fixed groove 34.

[0053] The outer periphery of the turntable 31 is provided with teeth, and a gear 32 is provided on one side of the turntable 31. The gear 32 is meshed with the turntable 31 through the teeth. The gear 32 is fixedly connected to the output shaft of the motor 33. The motor 33 is fixedly connected to the ventilation pipe 21.

[0054] A cleaning mechanism 4 is provided on the turntable 31. The cleaning mechanism 4 includes a plurality of drain pipes 41. The drain pipes 41 are distributed circumferentially on the turntable 31. Each drain pipe 41 is located between two adjacent fixed grooves 34. A sponge 42 is fixedly connected to the upper end of the drain pipe 41. The lower ends of the plurality of drain pipes 41 are fixedly connected to a manifold 43. The manifold 43 is fixedly connected to a sewage pipe 45 via a rotating sealing joint 44.

[0055] A protective shell 15 is provided outside the condensing mechanism 2, the rotating mechanism 3 and the cleaning mechanism 4, and a sewage pipe 45 and an external water pipe 24 extend out of the protective shell 15;

[0056] A sampling port 16 for taking out the sampling tube 35 is formed on one side of the protective shell 15 .

[0057] In this embodiment, by controlling the rotation of motor 33, turntable 31 drives sampling tube 35 or drain pipe 41 to be positioned directly below the lower end of condenser tube 22 for sampling or cleaning. Sampling tube 35 is secured to fixing slot 34 by a snap-fit mechanism. The user can insert sampling tube 35 into fixing slot 34 from below turntable 31. Multiple sets of fixing slots 34 and sampling tubes 35 are provided to improve sampling efficiency.

[0058] The cleaned sewage enters the collecting pipe 43 from the drainage pipe 41 and is finally discharged from the equipment through the sewage pipe 45.

[0059] The workflow is as follows:

[0060] First, connect the air guide tube 17 with the thread 11 to the reserved screw hole. When the air guide tube 17 rotates, the sealing gasket 12 and the pressure plate 13 on it gradually approach the boiler surface. Finally, the sealing gasket 12 fits the boiler surface and forms a seal under the pressure of the pressure plate 13. When sampling, first open the flow valve 14 to adjust the steam flow. The steam in the boiler enters the vent pipe 21 through the air guide tube 17 under the action of pressure. By controlling the rotation of the motor 32, the turntable 31 is driven to position the sampling tube 35 directly below the lower end of the condenser 22. Subsequently, the flow valve 14 is opened, and the steam enters the condenser 22 through the vent pipe 21. Because cooling water flows through the spring-loaded circulation tube 23 nested outside the condenser 22, the ambient temperature inside the condenser 22 is relatively low. Upon entering, the steam rapidly liquefies, forming water droplets that flow along the inner wall of the condenser 22 and into the sampling tube 35. During the condensation process, the cooling water within the spring-loaded circulation tube 23 absorbs heat, increasing its temperature and causing its density to decrease and flow upward, causing the higher-temperature cooling water to accumulate at the upper end of the spring-loaded circulation tube 23. This phenomenon ensures a higher ambient temperature at the junction of the vent tube 21 and the condenser 22, preventing premature liquefaction of the steam before entering the condenser 22. This prevents sample backflow and improves the efficiency of collecting the liquefied steam sample. After sample collection is complete, the flow valve 14 is closed, and the motor 32 is controlled to rotate, causing the turntable 31 to move the drain pipe 41 directly below the lower end of the condenser 22. At this point, the ball 25 contacts the sponge 42, shrinking toward the interior of the condenser 22 and compressing the return spring 26, causing the cable 27 to relax. Without the tension of the cable 27, the sealing ring 28 slides due to the contraction of the support spring 210 (the support spring 210 is initially extended), eventually aligning the opening 29 in the sealing ring 28 with the water inlet 211. This allows the cooling water in the spring circulation tube 23 to enter the condenser 22 (the cooling water in the spring circulation tube 23 is injected by the external water pipe 24, which injects a preset volume of water during this process and discharges the existing cooling water into the condenser 22). During this process, the lower end of the condenser 22 is in close contact with the sponge 42 and the drain pipe 41. Once the cooling water enters the condenser 22, it cannot be directly discharged (the sponge 42 slows the outflow of water). Instead, it accumulates in the condenser 22 (the cooling water accumulates after entering the condenser 22 and then slowly drains through the sponge 42). This cleans the inner wall of the condenser 22, preventing the next sample from being mixed with residues from the previous sample, thereby ensuring the accuracy of the sample. At the same time, since the cooling water absorbs heat during the liquefaction process, the condensed water temperature is higher, further improving the cleaning effect. After the cleaning and drainage are completed, the motor 33 drives the turntable 31 to rotate again, moving the next sampling tube 35 to the bottom of the condenser tube 22, ready for the next sampling.During this process, the ball 25 is no longer squeezed by the sponge 42, the reset spring 26 is stretched, the ball 25 resets downward, and the sealing ring 28 is pulled to move by the cable 27, and the support spring 210 is re-extended, so that the opening 29 is misaligned with the water inlet 211, thereby closing the water inlet 211.
