Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] First, the Joule-Thomson effect is introduced. In 1852, Joule and Thomson completed a throttling expansion experiment, which confirmed the temperature change phenomenon that occurs when the actual gas expands. This phenomenon was later named the Joule-Thomson effect (Joule-Thomson effect), referred to as the Jiao-Soup effect (J-T effect). In engineering, the engineering process using this natural physical phenomenon is usually called throttling process. The throttling process and another process called adiabatic expansion are two of the most commonly used methods for obtaining low temp...

Abstract

The invention belongs to the field of environment monitoring, and provides a gas monitoring instrument and system. The gas monitoring instrument comprises a base, a front gas chamber and a main gas chamber are arranged on the base, a buffer plate is arranged between the front gas chamber and the main gas chamber, through holes are distributed in the buffer plate, the head end of the front gas chamber is provided with a funnel-shaped gas inlet, the tail end of the main gas chamber is provided with a gas outlet, a guiding gutter is arranged between the gas outlet and the buffer plate, and the main gas chamber is provided with a gas sensor. Joule-Thomson effect is utilized to cool the gas, thus the water in gas can be conveniently removed without any drying agent, and the phenomenon that water is condensed on the surface of the gas sensor is avoided. Moreover, the front gas chamber is arranged before the main gas chamber so as to provide a buffer, which can absorb the gas flow impact brought by the air pump and reduce the noise of the sensor. The gas sensor can be directly soaked in the gas to be detected, the contact route is the shortest, and the responding speed of the monitoring instrument is greatly improved.

Description

technical field [0001] The invention belongs to the field of environmental monitoring, in particular to a gas monitor and a system. Background technique [0002] Environmental issues, especially air pollution, are a widespread concern at this stage. China's current stage is characterized by rapid industrial production and rapid infrastructure construction. The ensuing problem is that environmental problems are becoming more and more prominent. According to Dong Xiaolin’s calculation in “Analysis of Air Pollution Economic Losses in Central Cities in Guanzhong Region of Shaanxi Province”, as early as 2002, the loss caused by air pollution in Guanzhong region of Shaanxi Province was 0.99% of the GDP of that year. In addition, in 2013, the report "Towards an Environmentally Sustainable Future--National Environmental Analysis of the People's Republic of China" jointly completed by a working group composed of domestic and foreign environmental experts and a professional team fro...
