Description

Technical Field

[0001] The utility model relates to the technical field of gas composition monitoring, in particular to a gas pipeline gas composition monitoring device. Background Art

[0002] Gas generally refers to fuel gas, which can burn and release heat for use by residents and industrial enterprises. There are many types of fuel gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. When man-made gas is used by residents and industrial enterprises, it is necessary to use gas pipelines. During the transportation process, the gas in the pipeline needs to be monitored to ensure the composition of the gas.

[0003] The patent document with the prior art publication number CN112557621A provides a gas gas component monitoring and alarm device, including: a gas extraction and separation module, which is used for automatically opening a three-way valve when a light gas alarm is activated, and the gas enters the detection pipeline, and the gas enters the gas analysis module after being purified by an oil-gas separator; a gas analysis module, when the gas enters the gas collecting chamber through an air intake solenoid valve, the gas collecting chamber is connected to a combustible gas sensor, and the combustible gas sensor identifies the gas gas component and converts it into an electrical signal, and the electrical signal is saved in the gas analysis module; a remote monitoring module, which collects the electrical signal of the gas analysis module, obtains the gas gas component by analyzing the electrical signal, and remotely monitors the working state of the gas relay through the monitoring software, and issues an alarm when there is combustible gas in the gas. It can realize the functions of qualitative analysis, quantitative analysis, early alarm, data collection and analysis of gas gas components.

[0004] However, during the use of the existing gas pipeline gas composition monitoring device, the monitoring device needs to monitor the gas composition in the gas pipeline in real time, and the monitoring device needs to use electricity during the monitoring process. However, since most monitoring devices are powered by batteries and the monitoring devices cannot generate electricity by themselves, when the battery power is used up, the monitoring device needs to replace the battery. During this period, the monitoring device will stop monitoring the gas, thereby affecting the monitoring effect of the monitoring device. For this reason, we propose a gas pipeline gas composition monitoring device. Utility Model Content
