Description

Technical Field

[0001] The utility model belongs to the technical field of converter gas detection, and specifically relates to a portable device for detecting the total water content of converter gas. Background Art

[0002] Converter gas is an important energy medium in iron and steel enterprises. Usually, the humidity difference between dry air and gas is measured by using a humidity sensor or a hygrometer, and then the moisture content of converter gas is calculated through a calibration curve or other algorithms.

[0003] Currently, the existing detection equipment basically calculates the total water content through theoretical calculation, and cannot directly detect the total water content of converter gas, with high detection cost and long time consumption. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a portable device for detecting the total water content of converter gas, which can adjust the cooling water temperature of the condenser according to the measured temperature of the gas, and directly condense the saturated water content of the converter gas.

[0005] A portable device for detecting the total water content of converter gas according to the first aspect embodiment of the utility model includes a metering assembly, a condenser tube, and a drying assembly; the output end of the metering assembly is communicated with the condensation assembly, one output end of the condenser tube is communicated with the drying assembly, and the other output end of the condensation assembly is communicated with an iodine flask.

[0006] A portable device for detecting the total water content of converter gas according to the embodiment of the utility model has at least the following beneficial effects:

[0007] The device has a low cost and is composed of multiple independent components, each of which is installed in a different box. This modular design not only simplifies the manufacturing and maintenance processes, but also improves the flexibility of the equipment. In practical applications, each component can be freely combined according to needs, facilitating quick assembly and disassembly. Since each component can be moved independently and combined flexibly, the device can adapt to the detection requirements of different sampling points. Whether it is at different positions in the production site or in a laboratory environment for detection, it can respond quickly. In addition to portable applications, the device can also be fixedly installed at specific detection points and converted into a fixed detection device. This dual-purpose design meets the various needs of users in different scenarios and improves the practicality and return on investment of the equipment.

[0008] According to some embodiments of the present utility model, the metering assembly includes a gas flow meter and a thermometer. By using the gas flow meter and the thermometer in combination, the actual temperature and flow rate of the gas can be accurately measured, thereby achieving precise adjustment of the temperature of the condenser cooling water. This precise control can directly condense the saturated water volume of the converter gas, ensuring the accuracy and reliability of the detection results. At the same time, the gas flow meter and the thermometer can monitor the gas flow rate and temperature in real time, promptly reflecting the changes in the working conditions, enabling the equipment to quickly respond to environmental changes and perform dynamic adjustments.

[0009] According to some embodiments of the present utility model, the gas flow meter and the condensation assembly are connected by a rubber hose.

[0010] According to some embodiments of the present utility model, the contact point of the thermometer is located inside the rubber hose. The thermometer contact point can directly contact the gas flowing through the pipeline, ensuring the real-time and accuracy of temperature measurement. This direct contact measurement method reduces the interference of the ambient temperature on the measurement results, thereby improving the reliability of the data.

[0011] According to some embodiments of the present utility model, the drying assembly includes two interconnected wash bottles. The design of the two interconnected wash bottles can effectively increase the contact area between the gas and the desiccant, extend the path of the gas passing through the desiccant, thereby improving the drying efficiency. At the same time, the two wash bottles provide a redundant design. Even if one bottle fails or becomes saturated, the other bottle can still continue to function, ensuring the continuous working ability of the drying assembly and further improving the reliability and stability of the detection system.

[0012] According to some embodiments of the present utility model, at least one suction bottle is connected to the output end of the condenser tube.

[0013] According to some embodiments of the present utility model, the wash bottle is of a U-shaped pipe structure. The U-shaped pipe structure helps to more thoroughly remove impurities and moisture in the gas. Since the gas needs to turn multiple times and pass through the desiccant layer in the U-shaped pipe, it increases the depth and breadth of the purification treatment, enhancing the overall purification ability. At the same time, the U-shaped structure helps to prevent gas backflow, ensuring that the gas can only flow along the predetermined path, thereby improving the stability and safety of the device. This design effectively prevents gas turbulence and backflow in the pipeline, ensuring the smoothness of the drying and measurement processes.

[0014] According to some embodiments of the present utility model, the wash bottle is provided with discolored silica gel. The discolored silica gel has the characteristic of changing color when wet, enabling users to monitor the state of the desiccant in real time by observing the color change. Through the color change of the discolored silica gel, the saturated state of the desiccant can be detected in a timely manner, ensuring that the gas in the wash bottle is always in a dry state, thereby improving the accuracy and reliability of the detection results. Avoiding measurement errors caused by the failure of the desiccant.

[0023] Refer to Figure 1, a portable device for detecting the total water content of converter gas, comprising a sampling pipe 1, a metering component, a condenser 3 and a drying component; the output end of the metering component is communicated with the condensation component, one output end of the condenser 3 is communicated with the drying component, and the other output end of the condensation component is communicated with an iodine flask 4.

[0024] This device has a low cost and consists of multiple independent components, each installed in a different box. This modular design not only simplifies the manufacturing and maintenance processes but also improves the flexibility of the equipment. In practical applications, the components can be freely combined according to needs, facilitating quick assembly and disassembly. Since the components can be moved independently and combined flexibly, the device can adapt to the detection requirements of different sampling points. Whether at different positions in the production site or for detection in a laboratory environment, it can respond quickly. In addition to portable applications, the device can also be fixedly installed at specific detection points and converted into a fixed detection device. This dual-purpose design meets the various needs of users in different scenarios, improving the practicality of the equipment and the return on investment.

[0025] Furthermore, the metering component includes a gas flowmeter 2 and a thermometer. By using the gas flowmeter 2 and the thermometer in combination, the actual temperature and flow rate of the gas can be accurately measured, thereby enabling precise adjustment of the cooling water temperature of the condenser. This precise control can directly condense the saturated water content of the converter gas, ensuring the accuracy and reliability of the detection results. At the same time, the gas flowmeter 2 and the thermometer can continuously monitor the gas flow rate and temperature, promptly reflecting changes in the working conditions, enabling the equipment to quickly respond to environmental changes and make dynamic adjustments.

[0026] Preferably, the gas flowmeter 2 is connected to the condensation component through a rubber hose.

[0027] In this embodiment, the contact point of the thermometer is located inside the rubber hose. The thermometer contact point can directly contact the gas flowing through the pipeline, ensuring the real-time and accuracy of temperature measurement. This direct contact measurement method reduces the interference of the ambient temperature on the measurement results, thereby improving the reliability of the data.

[0028] Furthermore, the drying component includes two interconnected washing bottles 5. The design of the two interconnected washing bottles 5 can effectively increase the contact area between the gas and the desiccant, extend the path of the gas passing through the desiccant, thereby improving the drying efficiency. At the same time, the two washing bottles 5 provide a redundant design. Even if one bottle fails or becomes saturated, the other bottle can still continue to function, ensuring the continuous working ability of the drying component and further improving the reliability and stability of the detection system.

[0029] Preferably, at least one aspirating bottle is communicated with the output end of the condenser 3.

[0030] Furthermore, the scrubbing bottle 5 has a U-shaped pipe structure. The U-shaped pipe structure helps to more thoroughly remove impurities and moisture in the gas. Since the gas needs to turn multiple times and pass through the desiccant layer in the U-shaped pipe, it increases the depth and breadth of the purification process and improves the overall purification capacity. At the same time, the U-shaped structure helps to prevent gas backflow, ensuring that the gas can only flow along the predetermined path, thus improving the stability and safety of the device. This design effectively prevents gas turbulence and backflow in the pipeline, ensuring the smoothness of the drying and measurement processes.

[0031] Preferably, a discolored silica gel 6 is provided inside the scrubbing bottle 5. The discolored silica gel 6 has the characteristic of changing color when wet, enabling users to monitor the state of the desiccant in real time by observing the color change. Through the color change of the discolored silica gel 6, the saturation state of the desiccant can be detected in a timely manner, ensuring that the converter gas in the scrubbing bottle 5 is always in a dry state, thereby improving the accuracy and reliability of the detection results. It avoids measurement errors caused by the failure of the desiccant.

After cooling the gas, it is discharged from the outlet of the condenser 3; the condensed water enters the iodine flask 4 for collection;

[0039] 7) Stop the gas inlet after most of the discolored silica gel 6 in the two scrubbing bottles 5 has changed color during the whole process;
