Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas monitoring instruments, and in particular to a gaseous medium monitoring instrument that can be used to monitor whether there is leaked gas in circulating water. Background Technology
[0002] Circulating water systems are mainly divided into industrial and domestic types, both primarily aimed at water conservation. Industrial circulating water is mainly used in cooling systems, hence the name circulating cooling water. In factories, circulating cooling water is mainly used to condense steam, cool products or equipment, etc. When the product being cooled or the pipeline is damaged, the material may leak and mix into the circulating water. This not only affects the cooling effect and production efficiency but also severely reduces product yield and quality, and in severe cases, can even cause production accidents. If the material is oil-based, leakage can be quickly determined by observing the turbidity of the circulating water or other visible phenomena. However, leaks of gaseous media are difficult to detect with the naked eye in their early stages.
[0003] In existing technologies, to confirm whether there is a leak of gaseous media in circulating water, it is often necessary to physically separate the circulating water sample. The separated gas undergoes steps such as filtration, condensation, constant pressure treatment, and drying before being sent to a gas monitor for detection to determine its composition. Furthermore, most analyzers on the market have a single function, poor compatibility with probes from other brands, and some instruments have long analysis times, leading to data lag.
[0004] Therefore, it is necessary to design a new gaseous medium monitor to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a gaseous medium monitor to solve the problems existing in the gaseous medium monitors used to monitor whether there is gas leakage in circulating water.
[0006] To achieve the above-mentioned and other related objectives, this utility model is implemented by including the following technical solutions.
[0007] This utility model provides a gaseous medium monitor, which is used to monitor whether there is leaked gas in circulating water. The gaseous medium monitor includes at least: a sample inlet pipe, a gas collection assembly, and a conductivity monitor.
[0008] The conductivity monitor is installed in the gas collection assembly and is used to detect the conductivity of the medium in the gas collection assembly.
[0009] The gas collection component is connected to the sample inlet pipe and is fixedly installed at one end of the sample inlet pipe;
[0010] An exhaust valve is provided on the top of the gas collection assembly.
[0011] In one specific implementation, the gas collection assembly comprises an inner hopper and an outer hopper;
[0012] The inner hopper has a first chamber with its opening facing downwards, and the outer hopper has a second chamber with its opening facing upwards. The inner hopper is located in the second chamber of the outer hopper.
[0013] In one specific embodiment, the gaseous medium monitor further includes a water tank; the gas collection component is disposed in the water tank and is connected and fixed to the water tank.
[0014] In one specific embodiment, an exhaust valve is provided on the top of the inner hopper.
[0015] In one specific embodiment, the outer hopper is fixedly connected to the water tank; the inner hopper is connected to the sample inlet pipe and fixedly installed at one end of the sample inlet pipe; a conductivity monitor is installed in the inner hopper to detect the conductivity of the medium in the inner hopper.
[0016] In one specific embodiment, the gaseous medium monitor further includes an external component, which is fixedly connected to the water tank and communicates with the gas in the water tank.
[0017] In one specific embodiment, the gaseous medium monitor further includes a sampling tube, which is fixedly installed at the other end of the inlet pipe and extends into the circulating water pipe to facilitate sampling and testing of the circulating water.
[0018] In one specific embodiment, the gaseous medium monitor further includes a first valve and a flow meter, both installed on the sample inlet pipe. The first valve and flow meter are used to further control the amount of circulating water sample introduced.
[0019] In one specific embodiment, the gaseous medium monitor further includes an overflow valve, which is located inside the water tank, below the height of the top surface of the outer hopper. The overflow valve controls the liquid level in the water tank to ensure it does not exceed the height of the outer hopper.
[0020] In a more specific embodiment, the overflow valve includes a float overflow valve.
[0021] In one specific embodiment, the gaseous medium monitor further includes a drain pipe and a drain valve. The drain pipe is connected to the bottom of the water tank, and the drain valve is located on the drain pipe to control the discharge of liquid from the water tank.
[0022] In one specific embodiment, the external component is a gas qualitative and / or quantitative analysis device. For example, it could be a combustible gas meter, a VOC meter, or a hydrogen sulfide meter.
[0023] In one specific embodiment, the water tank is a transparent water tank. For example, the transparent water tank can be a transparent glass water tank, a transparent plastic water tank, etc.
[0024] In one specific embodiment, the inner container is a transparent inner container. For example, the transparent inner container could be a transparent glass inner container, a transparent plastic inner container, etc.
[0025] In one specific embodiment, the outer container is a transparent outer container. For example, the transparent outer container can be a transparent glass outer container, a transparent plastic outer container, etc.
[0026] This makes it easier for operators to observe the specific conditions inside the device, such as whether the probe of the external component is contaminated, whether there is gas accumulation in the inner hopper, etc.
[0027] Specifically, in actual use, the circulating water sample to be tested enters the inner hopper from the sampling pipe of the gaseous medium monitor, the exhaust valve is opened to allow the circulating water sample to fill the inner hopper, and then the exhaust valve is closed.
[0028] After the circulating water sample fills the inner hopper, if there is no leaked gaseous medium in the water sample, both the inner and outer hoppers will be full of water. The conductivity monitor will continuously monitor the liquid, and the reading will remain relatively stable. The gaseous medium monitor will continue to work normally. If a leak occurs and there is leaked gaseous medium in the water sample, the gas density will be less than the liquid density. According to the principle of water displacement and gas collection, the top of the inner hopper, which was originally full of circulating water, will accumulate gas, thereby pushing the circulating water out of the inner hopper. At this time, the conductivity monitor will not be able to contact the liquid and will display an abnormality and trigger an alarm.
[0029] Furthermore, as more and more gas accumulates, it overflows from the inner hopper and reaches the water tank, where it comes into contact with the external components for further gas detection.
[0030] As described above, this utility model provides a gaseous medium monitor that can be used to monitor whether there is gas leakage in circulating water. The gaseous medium monitor has a simple structure and can monitor circulating water without the need for equipment that can physically separate gas from water. At the same time, the gas analysis and measurement device of the gaseous medium monitor is external, and various gas analysis and measurement devices can be selected according to actual conditions, which has good compatibility and multiple functions. In addition, the gaseous medium monitor adopts a transparent shell, which makes it highly observable. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

Therefore, they have no substantial technical significance.

[0048] like Figure 1As shown, this embodiment provides a gaseous medium monitor, which is used to monitor whether there is gas leakage in circulating water. The gaseous medium monitor includes at least: a sample inlet pipe 1, a gas collection assembly 2, and a conductivity monitor 4.
[0049] The conductivity monitor 4 is installed in the gas collection assembly 2 and is used to detect the conductivity of the medium in the gas collection assembly 2.
[0050] The sample inlet pipe 1 is connected to the gas collection assembly 2 and is fixedly installed at one end of the sample inlet pipe 1;
[0051] An exhaust valve is provided on the top of the gas collection assembly 2.
[0052] In practical use, when detecting gas leaks in a circulating water network, the circulating water sample to be tested enters the gas collection assembly 2 through the inlet pipe 1, with the exhaust valve kept open to ensure the sample fills the assembly and allows any existing air to escape. The exhaust valve is then closed. After the gas collection assembly 2 is filled with the sample, if there is no leaking gaseous medium, the conductivity monitor 4 continues to detect liquid, and its reading remains relatively stable, while the gaseous medium monitor continues to operate normally. However, if a gaseous medium leaks, the gas density is lower than the liquid density. Based on the principle of the drainage gas collection method, gas will gradually accumulate at the top of the gas collection assembly 2, pushing the circulating water out. In this case, the conductivity monitor 4 cannot contact the liquid and can only detect the gaseous medium, triggering an alarm.
[0053] In a like Figure 1 In the specific embodiment shown, the gas collection component 2 consists of an inner hopper 21 and an outer hopper 22; the inner hopper 21 forms a first chamber with an opening facing downwards, and the outer hopper 22 forms a second chamber with an opening facing upwards, with the inner hopper 21 located in the second chamber of the outer hopper 22.
[0054] In a like Figure 1 In the specific embodiment shown, the gaseous medium monitor further includes a water tank 3; the gas collection component 2 is disposed in the water tank 3 and connected and fixed to the water tank 3. This application does not specifically limit the position of the gas collection component 2 in the water tank 3, as long as it exists within the water tank and allows circulating water to overflow from the gas collection component 2. As an example, such as... Figure 1 As shown, the gas collection component 2 is located in the water tank 3, fixed on the side wall of the water tank, and does not contact the top and top of the water tank.
[0055] More specifically, the top of the inner container 21 is provided with an air vent valve. This allows the air in the inner container 21 to be expelled during the initial water intake, thus ensuring that the inner container 21 is filled with water.
[0056] More specifically, such as Figure 1 As shown, the outer hopper 22 is connected and fixed to the water tank 3; the sample inlet pipe 1 is connected to the inner hopper 21, and the inner hopper 21 is fixedly connected to one end of the sample inlet pipe 1;
[0057] The conductivity monitor 4 is installed in the inner container 21 to detect the conductivity of the medium in the inner container 21.
[0058] In practical use, the circulating water sample to be tested enters the inner hopper 21 through the sampling pipe 1, keeping the exhaust valve open. After the inner hopper 21 is filled with the circulating water sample, the exhaust valve is closed. If there is no leaking gaseous medium in the water sample, the inner hopper 21 and outer hopper 22 of the gas collection assembly 2 will be filled with the water sample, the conductivity monitor 4 will detect the liquid, the value of the conductivity monitor 4 will remain relatively stable, and the gas medium monitor will continue to work normally. If a leak occurs and there is a leaking gaseous medium in the water sample, since the gas density is less than the liquid density, according to the principle of gas collection, the top of the inner hopper 21, which was originally filled with the water sample, will accumulate gas, thereby pushing the circulating water out of the inner hopper 21. At this time, the conductivity monitor 4 cannot contact the liquid and will display an abnormality and trigger an alarm.
[0059] In a like Figure 1 In the specific embodiment shown, the gaseous medium monitor further includes an external component 5, which is fixedly connected to the water tank 3 and communicates with the gas in the water tank 3.
[0060] Specifically, if there is a leaked gaseous medium in the water sample, as more and more gas accumulates at the top of the inverted inner hopper 21, the gas will fill and overflow the inner hopper 21, reaching the water tank 3, and thus coming into contact with the external connector 5 on the water tank 3 to achieve further detection and judgment of the gas.
[0061] like Figure 1 As shown, in a specific embodiment, the gaseous medium monitor further includes a sampling tube 6, which is fixedly installed at the other end of the inlet pipe 1 and extends into the circulating water pipe, thereby better realizing the sampling and detection of the circulating water.
[0062] like Figure 1 As shown, in one specific embodiment, the gaseous medium monitor further includes a first valve 8 and a flow meter 7, both mounted on the sample inlet pipe 1. The amount of circulating water sample is controlled by controlling the first valve 8, and quantitative detection of the water sample is achieved by observing the reading of the flow meter 7.
[0063] In one specific embodiment, the gaseous medium monitor further includes an overflow valve 9, which is located inside the water tank 3, below the height of the top surface of the outer hopper 22. This application does not specifically limit the type of overflow valve 9, as long as it can control the liquid level inside the water tank 3. Figure 1 As shown, the overflow valve 9 is a float overflow valve 9.
[0064] Specifically, when the liquid level in the water tank 3 reaches the position of the overflow valve 9, the overflow valve 9 will cause the liquid in the water tank 3 to flow out of the water tank 3 in one direction, so as to ensure that the liquid level in the water tank 3 is always lower than the top surface of the outer hopper 22, thereby avoiding affecting the normal operation of the inner hopper 21 and the outer hopper 22.
[0065] like Figure 1 As shown, in a specific embodiment, the gaseous medium monitor further includes a drain pipe and a drain valve 10. The drain pipe is connected to the bottom of the water tank 3, and the drain valve 10 is located on the drain pipe to control the discharge of liquid from the water tank 3.
[0066] In one specific embodiment, the external component 5 is a gas qualitative and / or quantitative analysis device. This application does not specifically limit the type of gas analysis and measurement device; it can be a combustible gas meter, a VOC meter, a hydrogen sulfide meter, etc. As an example, in a… Figure 1 In the embodiment shown, the external component 5 is a combustible gas measuring instrument.
[0067] In practical use, the readings of flow meter 7 and the gas analysis measuring device enable qualitative and quantitative analysis of the gas, facilitating further work.
[0068] In one specific embodiment, the water tank 3 is a transparent water tank. This application does not specifically limit the material of the transparent water tank, as long as it allows observation of the interior of the water tank 3. For example, it can be a transparent glass water tank, a transparent plastic water tank, etc. Figure 1 In the specific embodiment shown, the water tank 3 is a transparent glass water tank.
[0069] In one specific embodiment, the inner container 21 is a transparent inner container. This application does not specifically limit the material of the transparent inner container, as long as it allows observation of the interior of the inner container 21. For example, it can be a transparent glass inner container, a transparent plastic inner container, etc. Figure 1 In the specific embodiment shown, the inner hopper 21 is a transparent glass inner hopper.
[0070] In one specific embodiment, the outer container 22 is a transparent outer container. This application does not specifically limit the material of the transparent outer container, as long as it allows observation of the interior of the outer container 22. For example, it can be a transparent glass outer container, a transparent plastic outer container, etc. Figure 1 In the specific embodiment shown, the outer hopper 22 is a transparent glass outer hopper.
[0071] By setting up a transparent water tank, a transparent outer hopper, and a transparent inner hopper, the internal conditions can be observed and understood with the naked eye. For example, it is convenient to observe whether bubbles are generated inside, whether gas is accumulating at the top of the inner hopper 21, whether the detection probe of the external component 5 is working properly, and the liquid level in the water tank 3, etc.
[0072] In one specific embodiment, the downstream end of the flow meter 7 can also be equipped with an infrared light oil analyzer, an ultraviolet aromatic hydrocarbon analyzer, etc. This enables the gaseous medium monitor not only to monitor gases in the circulating water, but also to detect leaks of other media within the circulating water.
[0073] In practical use, in order to detect whether there is a gas leak in the circulating water system, the gas medium monitor is first connected to the circulating water network 11, and a circulating water sample is obtained through the sampling tube 6. The circulating water sample to be tested enters the inner hopper 21 through the sampling pipe 1, and the exhaust valve is kept open so that the inner hopper 21 is filled with the circulating water sample to be tested. Then the exhaust valve is closed. During the process, the amount of circulating water sample is adjusted through the first valve 8.
[0074] After the inner hopper 21 is filled with the circulating water sample to be tested, if there is no leaked gaseous medium in the water sample, the outer hopper 22 will also gradually fill with water sample. The conductivity monitor 4 will continuously detect the water sample liquid, and the reading of the conductivity monitor 4 will remain relatively stable. The gaseous medium monitor can maintain normal operation. If a leak occurs and there is leaked gaseous medium in the water sample, since the gas density is less than the liquid density, according to the principle of water drainage and gas collection, the top of the inner hopper 21, which was originally filled with water sample, will accumulate gas, thereby pushing the circulating water out of the inner hopper 21. At this time, the conductivity monitor 4 cannot contact the water sample liquid and will display an abnormality to trigger an alarm.
[0075] Furthermore, as more and more gas accumulates, it overflows from the inner hopper 21 and reaches the outer hopper 22 or the water tank 3, whereby the gas comes into contact with the external component 5, i.e., the gas analysis and measurement device, to achieve further qualitative and quantitative detection of the gas. Meanwhile, the water sample separated from the gas reaches the outer hopper 22, or even overflows into the water tank 3, and then flows out of the water tank 3 through the overflow valve 9 or the second valve 10.
[0076] In summary, the gaseous medium monitor of this invention can be used to monitor whether there is gas leakage in circulating water. The gaseous medium monitor has a simple structure and can monitor circulating water without the need for specific equipment that can physically separate gases from water. At the same time, the gas analysis and measurement device of the gaseous medium monitor is external, and various gas analysis and measurement devices can be selected according to actual conditions, which has good compatibility and multiple functions. In addition, the gaseous medium monitor adopts a transparent shell, which makes it highly observable.
[0077] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
