Device for detecting gas components

Abstract

The invention belongs to the field of gas environment monitoring equipment, and particularly relates to a device for detecting gas components. The device comprises a gas pipeline with a smooth and transparent middle part and an optical path component, the optical path component is used for irradiating and detecting gas in the gas pipeline in the middle, the two ends of the gas pipeline are respectively used as an inlet and an outlet of the gas, and the optical path component and the gas pipeline are independent of each other. The device has the advantages that: the gas pipeline and the optical component are independent from each other, and the detected gas is completely sealed in the pipeline, so that the pollution and impact effects of the detected gas on the optical component are fundamentally avoided, the service life of the device is prolonged, and the operation and maintenance cost is reduced. Compared with a gas chamber structure of traditional equipment and intermittent sampling characteristics thereof, the device uses a gas pipeline with a smooth and transparent middle part, so that continuous and smooth sampling of detected gas can be ensured, and the continuity and high real-time performance of a detection process are further realized; and meanwhile, impact noise and vibration can be reduced, and the stability of the detection process and the accuracy of detection results are improved.

Description

[0001] This application claims a divisional application of "a gas component detection device" with the application number 201811223535.X filed on October 19, 2018, and the original acceptance institution is in China. technical field [0002] The invention relates to the field of gas environment monitoring equipment, in particular to a device for detecting gas components. Background technique [0003] Gas sampling channel (referred to as gas circuit) and gas detection chamber (referred to as gas chamber) are common structures in devices used to detect gas components. Among them, the gas chamber is the core component of the detection device, and the gas circuit is usually used to sample the environment. Gas input and output gas chamber. During the working process of the traditional detection device, the gas to be tested enters the gas chamber through the gas path by autonomous diffusion or external force, and emits a characteristic spectrum under the illumination of the light ...

Problems solved by technology

However, the complexity of optical path design often brings high initial cost and maintenance cost

In addition, in the traditional detection device, the optical path components are directly installed in the gas under test, which easily affects the cleanliness of the gas under test and thus seriously affects the detection effect. It also needs to add pre-treatment structures and processes such as gas dust removal and dehumidification, which greatly improves the The overall cost of the detection device; at the same time, in addition to the solid / liquid suspended particles in the gas, components with corrosive effects are also key factors that affect the life of the optical path components in the detection device and even the entire machine
