Description

Technical Field

[0001] The present invention relates to the technical field of gas leak detectors, and particularly to a device, a system and a method for correcting data deviation of halogen leak detectors. Background Art

[0002] Halogen elements refer to the elements in Group VIIA of the periodic system. They include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At), collectively referred to as halogens. They all exist in nature as typical salts and are salt-forming elements. The simple substances of halogen elements are all diatomic molecules, and their physical properties change regularly. As the molecular weight increases, the dispersion force between halogen molecules gradually increases, the color becomes darker, and their melting point, boiling point, density, and atomic volume also increase in turn.

[0003] Halogen gas leak detectors are analytical instruments widely used in industries related to the production and use of halogen gases, such as chemical industry, refrigeration, and high-voltage electricity. Due to the chemical characteristics of the detection objects, such instruments are mostly used for leak detection, leakage alarm, and safety protection, so their metrological performance indicators are particularly important.

[0004] However, the data collected by existing halogen leak detectors using the principle of high-frequency magnetic field low-pressure ionization will deviate in different environments. Therefore, it is urgent to design a device for correcting the data deviation of halogen leak detectors. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a device, a system and a method for correcting data deviation of halogen leak detectors. By setting a device for correcting data deviation of halogen leak detectors at the front end of the halogen leak detector, the moisture in the gas entering the halogen leak detector is removed to solve the problem of data deviation of the halogen leak detector due to humidity differences in the natural environment.

[0006] The technical solutions provided by the present invention are as follows:

[0007] A device for correcting data deviation of a halogen leak detector, the halogen leak detector using the principle of high-frequency magnetic field low-pressure ionization, comprising:

[0008] A housing, the housing is provided with a chamber for gas flow, and the gas outlet of the chamber is used to connect with the halogen leak detector;

[0009] A dehumidification component for removing moisture in the halogen gas entering the chamber.

[0010] In this technical solution, the inventor found that during the use of leak detectors based on the principle of high-frequency magnetic field low-voltage ionization, they are greatly affected by moisture, and the level of moisture affects the voltage value generated by ionization. For example, in a natural environment without fluorine-containing gases at 60% humidity, the halogen leak detector generates a voltage value of 0.30V, while in a dry nitrogen environment (national standard nitrogen), the same halogen leak detector generates a voltage value of 0.14V. The actual application environment of the equipment is generally a natural environment, and the moisture in the natural environment is also unstable and changes at any time. Therefore, it is assumed that a halogen leak detector calibrated in a 60% humidity environment must, strictly speaking, be calibrated for the base number at any time as the moisture changes. As a leak detection tool used on-site, the moisture in the use environment is constantly changing and irregular, and it is impossible to have an environment with stable moisture. Thus, it can be seen that the voltage value signal generated by ionization, as the original data for obtaining the detected concentration of fluorine-containing gases, changes with humidity even when the concentration of fluorine-containing gases remains unchanged.

[0011] Therefore, the inventor believes that for such halogen leak detectors, the influence degree of moisture on the halogen leak detector can be studied and data processing can be carried out. After research, it is found that at different concentrations of halogen-containing gases, the influence of humidity on the voltage value generated by the halogen leak detector is inconsistent, and one-dimensional data processing cannot be performed in the program. Therefore, it is impossible to use the method of data processing to solve the problem of deviation of the halogen leak detector caused by the influence of moisture.

[0012] By setting up a device for correcting the data deviation of the halogen leak detector to remove moisture from the gas entering the halogen leak detector. At the same time, this device cannot hinder the entry and exit of halogen-containing gases, cannot adhere to halogen-containing gases, and cannot affect the technical parameters of the response time and recovery time in the halogen leak detector, thereby solving the problem of deviation of the halogen leak detector caused by the influence of moisture.

[0013] Preferably, the dehumidification component is a desiccant, and the desiccant is arranged in the chamber.

[0014] In this technical solution, when the halogen-containing gas with moisture passes through the hollow housing, the moisture is absorbed by the desiccant inside the housing, achieving the purpose of drying the gas. This device makes the voltage value generated by the halogen-containing gas with the same concentration in the halogen leak detector a definite value, that is, the only concentration value, and the influence of moisture on the voltage value of the halogen leak detector is eliminated.

[0015] Further preferably, the desiccant is calcium oxide desiccant;

[0016] Or, the desiccant is activated alumina desiccant.

[0017] In this technical solution, the moisture in the gas can be removed by physical adsorption method and chemical adsorption method. In the physical adsorption method, the desiccant adsorbs moisture without reacting with it. For example, activated alumina, activated carbon, etc. The inventor conducted experiments on different desiccants. Through experiments with activated alumina, a cylindrical desiccant kit was assembled. The test showed that when a mixed gas containing SF6 gas passed through a cylindrical desiccant kit with an inner diameter of about 10 mm and a length of 12 cm, there was no obvious visually distinguishable change in the response time and recovery time. However, the test using activated carbon as the desiccant showed that there was a significant impact on the response time and recovery time. In the chemical adsorption method, the desiccant can be selected such as calcium oxide. After the moisture passes through calcium oxide, Ca(OH)2 is produced by reaction, thereby adsorbing the moisture. However, this method is irreversible and the desiccant cannot be recycled.

[0018] Further preferably, it further includes at least two filter mesh covers. The desiccant is arranged between two adjacent filter mesh covers. The filter mesh cover is used to prevent the desiccant from entering the halogen leak detector.

[0019] In this technical solution, the desiccant also includes desiccant fragments or desiccant powder. The desiccant can be put into a perforated packaging bag, and then the packaging bag is placed in a hollow shell. However, this method is difficult to place. At the same time, the presence of the packaging bag will also affect the gas flow. By setting the filter mesh cover, the desiccant can be directly placed in the hollow shell, so that the desiccant particles cannot enter the halogen leak detector, and the gas drying efficiency is also improved.

[0020] Further preferably, connection heads are respectively arranged at both ends of the shell. The connection head is provided with a channel penetrating through the connection head. The filter mesh cover is arranged at one end of the channel. The connection head is adaptively connected to the shell, so that the channel is communicated with the chamber.

[0021] Further preferably, a sealing ring is arranged on the connection head. A sealing groove adapted to the sealing ring is arranged at the connection part of the shell and the connection head. The connection head and the shell clamp the sealing ring between the two of them.

[0022] Further preferably, plug heads are respectively arranged at both ends of the shell. The plug head is detachably connected to the shell. The plug head is used to form a closed structure for the shell.

[0023] In this technical solution, the purpose of setting the plug head is to block both ends of the shell through the plug head before the device for correcting the data deviation of the halogen leak detector is first used or when it is not used for a long time, so as to prevent the desiccant from absorbing moisture in the air and causing the desiccant to fail, resulting in additional cost investment.

[0024] Another technical solution provided by the present invention is as follows:

[0025] A system for correcting data deviation of a halogen leak detector, comprising the device for correcting data deviation of a halogen leak detector according to any one of the above claims, and further comprising a halogen leak detector, wherein the device for correcting data deviation of a halogen leak detector is connected to the halogen leak detector.

[0026] Preferably, a drying device is further included;

[0027] A drying agent is provided in the device for correcting data deviation of a halogen leak detector, and the drying device is used to remove moisture from the drying agent.

[0028] In this technical solution, since the drying agent absorbs moisture during use or storage, after the drying agent is close to saturation or saturated, its moisture absorption capacity decreases, and part or all of the moisture cannot be absorbed. At this time, the voltage value generated by the halogen gas with moisture when passing through the halogen leak detector will be affected by the moisture. By setting a drying device to remove the moisture in the drying agent, the activity of the drying agent is restored, so that the drying agent can be recycled and the use cost is reduced. The drying device can adopt the method of removing moisture by high temperature, the method of condensation or the method of flushing with dry nitrogen to remove moisture from the drying agent.

[0029] Another technical solution provided by the present invention is as follows:

[0030] A method for correcting data deviation of a halogen leak detector:

[0031] Applied to the device for correcting data deviation of a halogen leak detector according to any one of the above, wherein the halogen leak detector is a halogen leak detector based on the principle of high-frequency magnetic field low-voltage ionization; it is characterized by including:

[0032] Set up a device for correcting data deviation of a halogen leak detector, and connect the air outlet of the chamber to the halogen leak detector;

[0033] Remove moisture from the gas entering the halogen leak detector through the dehumidification component, so that the halogen gas entering the halogen leak detector is dry gas.

[0034] Preferably, after the halogen leak detector is used for a preset time, the device for correcting data deviation of a halogen leak detector and the halogen leak detector are placed together in a dry nitrogen environment with a slightly positive pressure, and the dry nitrogen is continuously flowed to remove the moisture in the drying agent in the chamber.

[0035] More preferably, after the halogen leak detector is used for a preset time, the device for correcting data deviation of a halogen leak detector is removed, and the device for correcting data deviation of a halogen leak detector is heated to remove the moisture in the drying agent in the chamber.

[0036] Compared with the prior art, the beneficial effects of the device, system and method for correcting data deviation of a halogen leak detector of the present invention are as follows:

[0037] In the present invention, during the use of a halogen leak detector product based on the principle of high-frequency magnetic field low-voltage ionization, it is greatly affected by moisture. The level of moisture affects the voltage value generated by ionization, thereby affecting the detection result of the halogen leak detector. By setting up a device for correcting data deviation of the halogen leak detector to remove moisture from the gas entering the halogen leak detector. At the same time, this device cannot impede the entry and exit of halogen gases, cannot adhere to halogen gases, and cannot affect the technical parameters of the response time and recovery time in the halogen leak detector, thus solving the problem of deviation caused by the influence of moisture on the halogen leak detector.

[0051] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will describe the specific embodiments of the present invention with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other embodiments can also be obtained.

[0052] As a specific embodiment, this embodiment provides a device for correcting data deviation of a halogen leak detector. The halogen leak detector adopts the principle of high-frequency magnetic field low-pressure ionization, and includes: a housing, the housing is provided with a chamber for gas flow, and the air outlet of the chamber is used to connect with the halogen leak detector; a dehumidification component, which is used to remove the moisture in the halogen gas entering the chamber.

[0053] In this embodiment, during the use of a halogen leak detector product based on the principle of high-frequency magnetic field low-pressure ionization, it is greatly affected by moisture. The level of moisture affects the voltage value generated by ionization, thereby affecting the detection effect of the halogen leak detector. By setting a device for correcting data deviation of the halogen leak detector to remove moisture from the gas entering the halogen leak detector. At the same time, this device cannot impede the entry and exit of halogen gases, cannot adhere to halogen gases, and cannot affect the technical parameters of the response time and recovery time in the halogen leak detector, thus solving the problem of deviation caused by the influence of moisture on the halogen leak detector.

[0054] Specifically, as Figure 1 , Figure 2 shown, the device body includes: a hollow housing 1, and a desiccant 2 provided inside the housing 1 for removing moisture. The housing 1 can be made of different materials, and the inner wall of the housing needs to be smooth to prevent the adhesion of halogen gases. For example: iron, stainless steel, copper, etc. in metal materials. Considering the adhesion of halogen gases to general non-metallic materials, polytetrafluoroethylene, etc. are generally selected for non-metallic materials. The housing 1 can be cylindrical, square or other shapes. The desiccant 2 is fully filled inside the housing 1 so that the moisture in the gas passing through the desiccant 2 can be fully absorbed.

[0055] In this embodiment, when the halogen gas with moisture passes through the hollow housing 1, the moisture is absorbed by the desiccant 2 inside the housing 1, achieving the purpose of drying the gas. This device makes the voltage value generated by the halogen leak detector for the same concentration of halogen gas a definite value, that is, the only concentration value, and the influence of moisture on the voltage value of the halogen leak detector is excluded.

[0056] Furthermore, as Figure 1 , Figure 2 shown, the two ends of the housing 1 are respectively provided with a first connector 3 and a second connector 4. The two ends of the housing 1 are respectively provided with a first threaded hole and a second threaded hole. A first sealing groove is provided on the first threaded hole, and a second sealing groove is provided on the second threaded hole. A first filter mesh cover 11 is fixed at one end of the first connector 3. A first sealing ring 5 is sleeved on the first connector 3. The first connector 3 is adapted to be screwed into the first threaded hole, clamping the first sealing ring 5 in the first sealing groove. A second filter mesh cover 12 is fixed at one end of the second connector 4. A second sealing ring 6 is sleeved on the second connector 4. The second connector is adapted to be screwed into the second threaded hole, clamping the second sealing ring 6 in the second sealing groove. Through the setting of the sealing rings, the tightness between the housing and the connecting parts can be ensured, effectively avoiding air leakage at the joints. The first and second connectors 3 and 4 are of hollow structures. The first and second filter mesh covers 11 and 12 are installed by screwing the first and second connectors 3 and 4 into the first and second threaded holes. Other structures that can achieve the connection between the filter mesh cover and the housing are also within the protection scope of this embodiment. The filter mesh covers in this embodiment are used to prevent the desiccant 2 from leaking out or entering the halogen leak detector.

[0057] In this embodiment, the desiccant 2 can also be placed in a perforated packaging bag, and then the packaging bag is placed in the hollow housing 1. However, this method is difficult to place. At the same time, the presence of the packaging bag also affects the gas flow. By setting a filter mesh cover, the desiccant 2 can be directly placed in the hollow housing 1, preventing the desiccant particles from entering the halogen leak detector and improving the gas drying efficiency.

[0058] Specifically, the desiccant 2 is a calcium oxide desiccant or an activated alumina desiccant. The removal of moisture in the gas can be achieved through physical adsorption and chemical adsorption methods. In the physical adsorption method, the desiccant adsorbs moisture without reacting with it. For example, activated alumina, activated carbon, etc. The inventor conducted experiments on different desiccants. Through experiments with activated alumina, a cylindrical desiccant kit was assembled. The test showed that when a mixed gas containing SF6 gas passed through a cylindrical desiccant kit with an inner diameter of about 10 mm and a length of 12 cm, there was no obvious visually distinguishable change in the response time and recovery time. However, using activated carbon as the desiccant in the experiment showed that the response time and recovery time were significantly affected. In the chemical adsorption method, the desiccant can be selected such as calcium oxide. After the moisture passes through calcium oxide, Ca(OH)2 is produced by the reaction, thereby adsorbing the moisture. However, this method is irreversible and the desiccant cannot be recycled.

[0059] In another embodiment, as Figure 1 、 Figure 2 shown, on the basis of the above embodiment, a first plug 7 and a second plug 8 are respectively provided at both ends of the housing 1. The first plug 7 and the second plug 8 are respectively detachably connected to the housing 1, and the first plug 7 and the second plug 8 are used to form a sealed structure for the housing 1.

[0060] In this embodiment, the purpose of setting the plugs is to block both ends of the housing 1 with the plugs when the device for correcting the data deviation of the halogen leak detector is not in use, preventing the desiccant 2 from absorbing moisture in the air and causing the desiccant 2 to fail, resulting in additional cost investment.

[0061] Specifically, as Figure 1As shown, the right end of the first connector 3 is screwed to fit the housing 1. The left end of the first connector 3 is provided with a first boss, and the outer side of the first boss is provided with a thread. The right side of the first plug 7 is provided with a first groove, and the first groove is provided with a thread adapted to the first boss. The first boss is screwed to fit the first groove, so as to realize that the first plug 7 seals one end of the housing 1. The left end of the second connector 4 is screwed to fit the housing 1. The right end of the second connector 4 is provided with a second boss, and the outer side of the second boss is provided with a thread. The left side of the second plug 8 is provided with a second groove, and the second groove is provided with a thread adapted to the second boss. The second boss is screwed to fit the second groove, so as to realize that the second plug 8 seals one end of the housing 1.

[0062] In a modified embodiment of the above embodiment, as Figure 3 shown, the left end of the second connector 4 is screwed to fit the housing 1. The right end of the second connector 4 is provided with a second boss, and the inner wall of the hollow second boss is provided with a thread. The right side of the second plug 8 is provided with a third boss, and the outer side of the third boss is provided with a thread adapted to the inner wall of the hollow second boss. The third boss is screwed to fit the inner wall of the second boss, so as to realize that the second plug 8 seals one end of the housing 1. It should be noted that the first plug 7 can also be connected to the housing 1 with this structure.

[0063] In another embodiment, as Figure 4 shown, on the basis of the above embodiment, this embodiment provides a system for correcting data deviation of a halogen leak detector, including a device for correcting data deviation of a halogen leak detector and a halogen leak detector 9. The device for correcting data deviation of a halogen leak detector is connected to the halogen leak detector 9. Of course, for the convenience of using the halogen leak detector 9, the system for correcting data deviation of a halogen leak detector may further include a detection head 10. Both ends of the device for correcting data deviation of a halogen leak detector are detachably connected to the halogen leak detector 9 and the detection head 10 respectively.

[0064] Specifically, as Figure 1 、 Figure 4As shown in the figure, a device for correcting the data deviation of a halogen leak detector is used to remove moisture in the gas entering the halogen leak detector based on the principle of low-pressure ionization in a high-frequency magnetic field. It includes: a device body, which is used to correct the deviation of the detection data of the halogen leak detector caused by moisture. The device body includes: a hollow housing 1, and a desiccant 2 disposed inside the housing 1 for removing moisture. First and second connectors 3 and 4 are respectively provided at both ends of the housing 1. First and second threaded holes are respectively provided at both ends of the housing 1. A first sealing groove is provided on the first threaded hole, and a second sealing groove is provided on the second threaded hole. A first filter mesh cover 11 is fixed at one end of the first connector 3. A first sealing ring 5 is sleeved on the first connector 3. The first connector 3 is adaptively screwed with the first threaded hole to clamp the first sealing ring 5 in the first sealing groove. A second filter mesh cover 12 is fixed at one end of the second connector 4. A second sealing ring 6 is sleeved on the second connector 4. The second connector is adaptively screwed with the second threaded hole to clamp the second sealing ring 6 in the second sealing groove. The first and second connectors 3 and 4 are of a hollow structure. The first and second filter mesh covers 11 and 12 are installed by screwing the first and second connectors 3 and 4 with the first and second threaded holes.

[0065] Furthermore, a desiccant 2 is provided in the device for correcting the data deviation of the halogen leak detector, and a drying device is provided in the system for correcting the data deviation of the halogen leak detector. The drying device is used to remove moisture from the desiccant 2. Since the desiccant 2 absorbs moisture during use or storage, after the desiccant 2 is nearly saturated or saturated, its moisture absorption capacity decreases, and part or all of the moisture cannot be absorbed. At this time, the voltage value generated when the halogen gas with moisture passes through the halogen leak detector 9 will be affected by moisture. By setting the drying device to remove the moisture in the desiccant 2, the activity of the desiccant 2 is restored, enabling the desiccant 2 to be recycled and reducing the use cost. The drying device can adopt methods such as high-temperature moisture removal, condensation, or drying nitrogen flushing to remove moisture from the desiccant.

[0066] In another embodiment, based on the above embodiment, this embodiment provides a method for correcting the data deviation of a halogen leak detector: A device for correcting the data deviation of the halogen leak detector is provided at the detection port of the halogen leak detector to remove moisture from the gas entering the halogen leak detector. The halogen leak detector is a halogen leak detector based on the principle of low-pressure ionization in a high-frequency magnetic field. The purpose of moisture removal is to correct the deviation of the detection data of the halogen leak detector caused by moisture. By setting the device for correcting the data deviation of the halogen leak detector to remove moisture from the gas entering the halogen leak detector, at the same time, this device cannot hinder the entry and exit of halogen gas, cannot adhere to halogen gas, and cannot affect the technical parameters of the response time and recovery time in the halogen leak detector, thereby solving the problem of deviation of the halogen leak detector caused by moisture.

[0067] Furthermore, a desiccant is provided in the device for correcting the data deviation of the halogen leak detector. The desiccant can be activated alumina desiccant. After the halogen leak detector has been used for a preset time, since the desiccant 2 absorbs moisture during use or storage, after the desiccant 2 approaches saturation or becomes saturated, its ability to absorb moisture decreases, and part or all of the moisture cannot be absorbed. At this time, the voltage value generated by the halogen gas with moisture when passing through the halogen leak detector 9 will be affected by the moisture; the device for correcting the data deviation of the halogen leak detector is removed, and by removing the moisture in the desiccant 2, the activity of the desiccant 2 is restored, so that the desiccant 2 can be recycled, reducing the use cost. The following methods can be used to remove the moisture in the desiccant 2: First, place the device for correcting the data deviation of the halogen leak detector in a dry nitrogen environment, and use the continuous flow of dry nitrogen to remove the moisture in the desiccant; Second, heat the device for correcting the data deviation of the halogen leak detector to remove the moisture in the desiccant; Third, place the device for correcting the data deviation of the halogen leak detector and the halogen leak detector together in a dry nitrogen environment with a slightly positive pressure, and use the continuous flow of dry nitrogen to remove the moisture in the desiccant in the chamber.

[0068] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0069] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of the present invention.
