Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, and more specifically, to an industrial gas online monitoring device. Background Art

[0002] In the production process of industrial gases, it is usually necessary to monitor the composition or concentration of the produced industrial gases in real time to quickly grasp the real-time status of the industrial gases. At this time, an online monitoring sensor assembly is needed to monitor the industrial gases in real time. However, since the temperature of the monitored industrial gases is sometimes relatively high, the prior art publication number CN215641095U discloses an industrial gas online monitoring device. When the temperature of the industrial gas entering the air inlet cavity from the first air inlet pipe is low, the industrial gas is sequentially transmitted from the air inlet cavity, the second exhaust pipe, the first heat exchange pipe, the second air inlet pipe, the air outlet cavity, and the first exhaust pipe to the online monitoring sensor assembly for real-time monitoring. Since the first heat exchange pipe is located in the heating cavity, the heating cavity can increase the temperature of the industrial gas in the first heat exchange pipe, so that the temperature of the industrial gas reaching the online monitoring sensor assembly is more appropriate, so as to avoid damage to the online monitoring sensor assembly due to excessively low industrial gas temperature.

[0003] When the above device is in use, it can convert the industrial gas into a suitable temperature and then transmit it to the online monitoring sensor assembly for real-time monitoring, thereby avoiding the online monitoring sensor assembly from being damaged by higher or lower temperatures, thereby reducing production costs. However, its structure is relatively complex, and when the gas detection component fails, it is inconvenient to disassemble, making maintenance and replacement more cumbersome. Utility Model Content
