Description

Technical Field

[0001] The utility model relates to the technical field of waste gas sampling equipment, in particular to a sampling device for industrial waste gas detection. Background Technique

[0002] With the rapid development of industrialization, the problem of waste gas emissions generated in the industrial production process has become increasingly serious, posing a serious threat to the environment and human health. In order to effectively control and reduce the pollution of industrial waste gas to the environment, it is particularly important to accurately detect and analyze the waste gas. Industrial waste gas detection not only requires efficient and accurate detection instruments, but also reliable sampling devices to collect representative waste gas samples.

[0003] Traditional industrial waste gas sampling devices often have problems such as complex structure, inconvenient installation, low sampling efficiency, and easy leakage, making it difficult to meet the needs of modern industrial waste gas detection. The fixing methods of some sampling devices on the exhaust pipe are not firm enough, and they are prone to loosen due to vibration or air flow impact, resulting in sampling failure or inaccurate data; at the same time, if the connection components during the sampling process have poor sealing performance, it is also easy to cause waste gas leakage and affect the sampling quality. Traditional sampling devices are cumbersome to operate when replacing the gas collecting bottle or adjusting the sampling parameters, requiring a large amount of time and manpower, and reducing the work efficiency. Therefore, we propose a sampling device for industrial waste gas detection. Content of the Utility Model

[0021] Embodiment

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a sampling device for industrial waste gas detection includes an exhaust pipe 1. There are two connecting plates 2, front and rear, arranged on the side wall of the exhaust pipe 1. Threaded holes are penetrated through the left sides of the two connecting plates 2, front and rear. A fixing bolt 3 is arranged in the threaded holes through threaded connection. At this time, under the action of the fixing bolt 3, the two connecting plates 2, front and rear, can be installed and fixed. A fixing nut 4 is also arranged on the fixing bolt 3 through threaded connection. Under the action of the fixing nut 4, the connection and fixing quality of the fixing bolt 3 to the two connecting plates 2, front and rear, is ensured.

[0023] An intake pipe 5 is arranged inside the exhaust pipe 1. A number of through holes 501 are evenly arranged on the intake pipe 5. A connecting pipe 6 is also arranged on the exhaust pipe 1. The air outlet end of the intake pipe 5 is connected to the connecting pipe 6. A placing table 17 is also arranged on the right sides of the two connecting plates 2, front and rear. A gas collecting bottle 16 is arranged on the placing table 17. The air inlet end of the gas collecting bottle 16 is connected to the connecting pipe 6 through an outlet pipe 14. At this time, when it is necessary to sample the waste gas inside the exhaust pipe 1, the waste gas enters the intake pipe 5 through the through holes 501, and then enters the gas collecting bottle 16 through the outlet pipe 14, thus completing the sampling work of the waste gas. A valve 15 is also arranged on the outlet pipe 14. Under the action of the valve 15, the rate of the waste gas entering the gas collecting bottle 16 can be controlled, and at the same time, the waste gas collected in the gas collecting bottle 16 can be retained, thereby ensuring the sampling quality of the waste gas by the gas collecting bottle 16, reducing the occurrence of waste gas leakage, and ensuring the use efficiency of the gas collecting bottle 16.

[0024] An installation base 7 is also provided on the connecting pipe 6. At this time, under the action of the installation base 7, the connection quality between the connecting pipe 6 and the exhaust pipe 14 is ensured, and thus the exhaust gas sampling quality is guaranteed.

[0025] A number of fixing plates 8 are evenly arranged on the side wall of the installation base 7. Through holes are provided through the fixing plates 8. A sliding rod 10 is arranged in the through holes through a sliding connection. A sliding plate 9 is arranged at the inner end of the bottom of the sliding rod 10. A plug rod is arranged on the outer wall of the sliding plate 9. A clamping block 13 is arranged on the exhaust pipe 14. A number of jacks for cooperating with the plug rod are evenly arranged on the side wall of the clamping block 13. At this time, under the action of the plug rod and the jacks, the connection quality between the connecting pipe 6 and the exhaust pipe 14 is ensured, and to a certain extent, the subsequent exhaust gas sampling efficiency and quality are guaranteed.

[0026] A return spring 11 is sleeved on the outer side of the sliding rod 10. One end of the return spring 11 is connected to the fixing plate 8, and the other end of the return spring 11 is connected to the sliding plate 9. At this time, under the action of the return spring 11, the connection quality between the plug rod and the jack is ensured, and further the connection quality between the exhaust pipe 14 and the connecting pipe 6. A handle 12 is arranged at the outer end of the sliding rod 10. Under the action of the handle 12, it is convenient to move the plug rod.

[0027] During actual use, the front and rear connecting plates 2 are firmly installed on the side wall of the exhaust pipe 1 through the fixing bolts 3 and the fixing nuts 4 to ensure the stable connection between the sampling device and the exhaust pipe 1. Subsequently, when the exhaust gas flows in the exhaust pipe 1, it is inhaled into the intake pipe 5 through the through holes 501 evenly distributed on the intake pipe 5. These through holes 501 allow the exhaust gas to enter evenly to ensure the representativeness of the sampling. The exhaust gas entering the intake pipe 5 then flows through the connecting pipe 6 to the gas collecting bottle 16. At the connection between the connecting pipe 6 and the exhaust pipe 14, the installation base 7 provides stable support to ensure the firm and leak-free connection between the two. At the same time, the mechanism composed of the fixing plate 8, the sliding rod 10, the sliding plate 9 and the plug rod on the side wall of the installation base 7 further enhances the connection reliability. By moving the handle 12, the sliding plate 9 drives the plug rod to slide along the sliding rod 10, so that the plug rod is inserted into the jacks of the clamping block 13 on the exhaust pipe 14 to achieve a tight connection. The return spring 11 ensures that the plug rod can automatically reset and stay in the jack when not under external force, further stabilizing the connection. When the exhaust gas flows through the connecting pipe 6 and the exhaust pipe 14 to the gas collecting bottle 16, the valve 15 plays a key control role. The operator can adjust the opening degree of the valve 15 according to needs, so as to control the rate of the exhaust gas entering the gas collecting bottle 16 and ensure the accuracy and representativeness of the sampling volume. When the gas collecting bottle 16 is filled with the exhaust gas, the valve 15 is closed, and the exhaust gas can be stored in the gas collecting bottle 16 for subsequent analysis.
