Description

Technical Field

[0001] The utility model relates to environmental protection technology and equipment for use thereof, in particular to waste gas detection, and specifically to a high-temperature organic waste gas detection device. Background Art

[0002] In the treatment of organic waste gas from electronic component sintering, portable PID detectors are commonly used to measure organic waste gas concentrations. These instruments utilize photoionization technology, or PID, and are characterized by their compact size and fast response. However, they are subject to strong interference at high temperatures, making it difficult to accurately measure high-temperature waste gas concentrations and prone to damage to components. Therefore, the detection temperature is typically below 80°C. Sintering waste gas is typically hot and contains moisture and particulate matter, which can damage PID detectors and significantly shorten their service life.

[0003] When treating the waste gas from the sintering of electronic components, processes involving combustion, such as catalytic combustion, are usually used. The temperature of the gas emitted after combustion treatment is higher, reaching over 100°C, making it inconvenient to directly use a PID detector for detection.

[0004] At present, there are three general methods for treating high-temperature organic waste gas that needs to be detected:

[0005] 1) Use a portable FID detector for detection: This instrument uses hydrogen ion flame technology and is insensitive to temperature conditions. However, it is relatively large compared to a PID detector, making it difficult to carry. It also requires an external power supply, which limits its use scenarios.

[0006] 2) Take samples first and test after cooling: This method cannot detect continuously and cannot reflect the rapid and continuous changes in gas concentration. In addition, the container collecting the waste gas is at risk of leakage and dilution during transportation.

[0007] 3) If the high-temperature exhaust gas flows into the main exhaust pipe, it is tested at the main exhaust pipe and the theoretical concentration is obtained by calculation: However, the height of the exhaust pipe detection port is generally set high, and frequent climbing of the detection platform increases the workload, and the calculated value is not as accurate as direct measurement.

[0008] Therefore, in the field work of the sintering waste gas treatment industry, there is an urgent need for a device that can reduce the temperature of high-temperature organic waste gas and facilitate direct detection using a PID detector.

[0009] Therefore, it is necessary to provide a high-temperature organic waste gas detection device to solve the above problems. Utility Model Content

[0010] The purpose of the utility model is to provide a high-temperature organic waste gas detection device.

[0011] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0012] A high-temperature organic waste gas detection device includes a heat dissipation and cooling insert module, the lower portion of the heat dissipation and cooling insert module is connected to a detection port through a sealing plug, and the upper portion of the heat dissipation and cooling insert module is provided with a filter-type connector;

[0013] The sealing plugging part is used as the connecting sealing end between the detection port and the lower part of the heat dissipation and cooling insert module. After the connection, the high-temperature organic waste gas is introduced into the heat dissipation and cooling insert module to form a high-efficiency organic waste gas cooling structure. The cooled organic waste gas is introduced into the PID detector through the corresponding filter connector for detection, forming a pre-cooling high-temperature organic waste gas detection structure.

[0014] Furthermore, the sealing plugging member is made of cotton or plastic which does not react with exhaust gas components and is not easily breathable.

[0015] Furthermore, the heat dissipation cooling insert module includes a metal pipe, on which a plurality of heat dissipation fins are provided via a fixed connection portion.

[0019] Furthermore, the filter connector has built-in F5 grade primary filter cotton.

[0020] Furthermore, the length of the metal pipe is selected to suit the application and the metal pipe is bent according to the requirements of the application.
