Description

Technical Field

[0001] This utility model relates to the field of gas analysis technology, and more specifically, to an anti-erosion gas analyzer. Background Technology

[0002] Zirconia analyzers are devices used to measure oxygen and combustible gases. They are mainly used in petrochemical, gas plants and other related industries. Flue gas contains a large amount of dust and other impurities. When flue gas flows through the guide tube and comes into contact with the detector probe, the probe will be damaged over time. Furthermore, the direct impact of flue gas on the probe will also damage the device.

[0003] Among them, the patent with announcement number CN221667726U discloses a rotary anti-erosion zirconia oxygen gas analyzer, including a guide tube, an air inlet pipe fixedly installed on the outside of the guide tube, an air outlet pipe fixedly installed on the outside of the guide tube, a filter mechanism set inside the guide tube, a fixing mechanism set on the top of the guide tube, and a zirconia oxygen analyzer body set on the top of the guide tube.

[0004] In operation, this structure uses flue gas to drive the impeller to rotate, which in turn rotates the shaft. This causes the scraper to clean the filter plate surface, extending the filter plate's lifespan. The guide plate and semi-circular baffle prevent flue gas convection, further extending the lifespan of the zirconia oxygen analyzer and improving the device's efficiency. Rotating the rotating block causes the sliding column to slide within its groove, simultaneously moving the clamping block inward to secure the zirconia oxygen analyzer. This makes disassembly and installation of the zirconia oxygen analyzer more convenient. However, this structure is not conducive to gas flow guidance during operation, and the gas does not diffuse quickly enough during analysis, resulting in poor analytical performance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-erosion gas analyzer, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: an anti-erosion gas analyzer, including a base, on which a flow guiding analysis component is provided;

[0007] The flow guiding analysis component includes a flow guiding pipe disposed on the top of the base, a one-way valve for flow guiding disposed on the top of the flow guiding pipe, a first flow diversion pipe for flow guiding disposed on one side of the one-way valve, and a second flow diversion pipe for flow guiding disposed on the other side of the one-way valve.

[0008] One end of the first and second diversion pipes is provided with a diffuser spiral pipe for guiding the flow. The inner wall of the diffuser spiral pipe is provided with an exhaust groove, and a central protective cylinder is provided in the middle of the diffuser spiral pipe.

[0009] As can be seen, in the above technical solution, after the airflow is dispersed in the central protective cylinder, it comes into contact with the main body of the gas analyzer and is analyzed by the main body of the gas analyzer. At the same time, the airflow dispersion method can effectively avoid the airflow from scouring and causing structural damage. The airflow is transported in the guide pipe and transferred through the one-way valve, and then split through the first and second split pipes. After that, the airflow is transported through the gas dispersion spiral pipe and then discharged through the exhaust groove. The spiral arrangement of the gas dispersion spiral pipe makes it easy for the airflow to be dispersed to different positions in the central protective cylinder through the exhaust groove, which facilitates the rapid dispersion of the airflow and makes it easy for the gas analyzer main body to analyze it.

[0010] Optionally, in one possible implementation, the central protective cylinder is connected to the exhaust trough and is snapped into the gas dispersing spiral tube. The vertical cross-sectional shape of the gas dispersing spiral tube is set to a spiral shape. The gas analyzer body is embedded in the middle of the central protective cylinder. The gas analyzer body is snapped into the central protective cylinder. An exhaust hood is provided on the top of the gas analyzer body. The exhaust hood is threadedly connected to the gas dispersing spiral tube. A protective cover is provided on one side of the surface of the one-way valve. A pressure gauge is provided inside the protective cover. An air inlet is provided at the bottom of the one-way valve. The air inlet is connected to the one-way valve. A valve is provided on the air inlet. The air inlet is connected to the guide pipe. The guide pipe is connected to the one-way valve through a flange.

[0011] As can be seen, in the above technical solution, the airflow after the subsequent analysis is completed is discharged through the exhaust hood, and the pressure gauge makes it easy to detect the flow rate during the analysis, ensuring the diversity and accuracy of the analysis. The airflow is delivered to the guide pipe through the air inlet, and the flow rate can also be adjusted by the valve.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up the flow guiding analysis component, compared with the existing technology, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the airflow is transported in the flow guiding pipe, transferred through the one-way valve, and then split through the first and second split pipes. After that, the airflow is transported through the gas dispersing spiral pipe and then discharged through the exhaust groove. The spiral arrangement of the gas dispersing spiral pipe makes it easy for the airflow to be dispersed to different positions in the central protective cylinder through the exhaust groove, which facilitates the rapid dispersion of the airflow and makes it easy for the gas analyzer to be analyzed by the main body.

[0014] Furthermore, after the airflow is dispersed within the central protective cylinder, it comes into contact with the main body of the gas analyzer and is analyzed by the gas analyzer. At the same time, the airflow dispersion method can effectively prevent the airflow from scouring the structure and causing structural damage. After the analysis is completed, the airflow is discharged through the exhaust hood, and the pressure gauge makes it easy to detect the flow rate of the airflow during analysis, ensuring the diversity and accuracy of the analysis.

[0021] 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.

[0022] As attached Figure 1 - Figure 4The illustrated anti-erosion gas analyzer utilizes a flow-guiding analysis component mounted on the base 1. Airflow is transported through the flow-guiding pipe 2, transferred via a one-way valve 3, and then split through the first and second split pipes 4 and 5. The airflow is then transported through a gas-dispersing spiral pipe 6 and discharged through an exhaust trough 12. The spiral design of the gas-dispersing spiral pipe 6 facilitates the dispersion of airflow to different locations within the central protective cylinder 7, enabling rapid airflow dispersion and subsequent analysis by the gas analyzer body 8. After dispersion within the central protective cylinder 7, the airflow contacts the gas analyzer body 8 for analysis. This airflow dispersion effectively prevents erosion and structural damage. After analysis, the airflow is discharged through an exhaust hood 9, and a pressure gauge 11 facilitates the detection of the flow rate during analysis, ensuring the diversity and accuracy of the analysis. The specific structural configuration of the component is as follows.

[0023] The flow analysis component includes a flow guide pipe 2 set on the top of the base 1, a one-way valve 3 for flow guidance set on the top of the flow guide pipe 2, a first diversion pipe 4 for flow guidance set on one side of the one-way valve 3, and a second diversion pipe 5 for flow guidance set on the other side of the one-way valve 3.

[0024] One end of the first diversion pipe 4 and the second diversion pipe 5 is provided with a diffuser spiral pipe 6 for guiding the flow. The inner wall of the diffuser spiral pipe 6 is provided with an exhaust groove 12, and the middle part of the diffuser spiral pipe 6 is provided with a central protective cylinder 7.

[0025] The central protective cylinder 7 is connected to the exhaust trough 12 and is also engaged with the gas dispersing spiral pipe 6. The vertical cross-section of the gas dispersing spiral pipe 6 is spiral-shaped. The gas analyzer body 8 is embedded in the middle of the central protective cylinder 7 and is engaged with the central protective cylinder 7. An exhaust hood 9 is provided on the top of the gas analyzer body 8 and is threadedly connected to the gas dispersing spiral pipe 6. A protective cover 10 is provided on one side of the surface of the one-way valve 3 and a pressure gauge 11 is provided inside the protective cover 10. An air inlet 13 is provided at the bottom of the one-way valve 3 and is connected to the one-way valve 3. A valve 14 is provided on the air inlet 13 and is connected to the guide pipe 2. The guide pipe 2 is connected to the one-way valve 3 through a flange.

[0026] When using the above structure, the staff installs the device at the designated location. The airflow is delivered to the guide pipe 2 through the air inlet 13. At the same time, the flow rate can be adjusted by the valve 14. After the airflow is delivered in the guide pipe 2, it is transferred through the one-way valve 3 and then split through the first split pipe 4 and the second split pipe 5. After that, the airflow is delivered through the gas dispersion spiral pipe 6 and then discharged through the exhaust groove 12. Due to the spiral arrangement of the gas dispersion spiral pipe 6, the airflow is easily dispersed to different positions in the central protective cylinder 7 through the exhaust groove 12, which facilitates the rapid dispersion of the airflow and makes it easy for the gas analyzer body 8 to perform analysis.

[0027] Furthermore, after the airflow is dispersed within the central protective cylinder 7, it comes into contact with the main body 8 of the gas analyzer and is analyzed by the main body 8. At the same time, the airflow dispersion method can effectively prevent the airflow from scouring the structure and causing structural damage. After the subsequent analysis is completed, the airflow is discharged through the exhaust hood 9, and the pressure gauge 11 makes it easy to detect the flow rate of the airflow during analysis, ensuring the diversity and accuracy of the analysis.

[0028] Unlike existing technologies, this application discloses an anti-erosion gas analyzer. Airflow is transported within the guide pipe 2, transferred via a one-way valve 3, and then split through a first split pipe 4 and a second split pipe 5. The airflow is then transported through a gas dispersion spiral pipe 6 and discharged through an exhaust trough 12. The spiral design of the gas dispersion spiral pipe 6 facilitates the dispersion of the airflow to different locations within the central protective cylinder 7, enabling rapid airflow dispersion and subsequent analysis by the gas analyzer body 8. After dispersion within the central protective cylinder 7, the airflow comes into contact with the gas analyzer body 8 for analysis. Simultaneously, the airflow dispersion effectively prevents erosion and structural damage caused by airflow. After analysis, the airflow is discharged through an exhaust hood 9, and a pressure gauge 11 facilitates the detection of the flow rate during analysis, ensuring the diversity and accuracy of the analysis.

[0029] 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, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
