Gas analyzer

Abstract

The invention relates to a gas analyzer. The gas analyzer comprises an alloy substrate, a main controller, a hollow cathode lamp, a laser module, a light shielding device, a gas chamber, a detection and analysis module, a gas inlet module, a compensation module, a data acquisition module, a time control module, a power supply module, a gas impurity detection device, a gas leakage detection device, an alarming device, an automatic stopping module and a protection shell. The gas analyzer has good high-temperature-resisting and corrosion-resisting performances so that the instrument can be reliably used for a long period; furthermore, a wrong result caused by the fact that impurities are doped into a gas sample also can be completely avoided, further loss of production and researches is avoided, and gas leakage can be found in time; the gas analyzer has a simple structure and commonality, sensitive response on a lot of substances, a wide measurement range, rapid response and a stable response signal.

Description

technical field [0001] The invention relates to the field of gas detection, in particular to a gas analyzer. Background technique [0002] The gas analyzer is a digital instrument that monitors the concentration of flue gas emitted by pollution sources in real time, completes function settings, and communicates with the host computer in real time. It provides technical support for the validity review of environmental monitoring data, risk prevention and emergency management of major pollution accidents. An important part of the pollution source monitoring system. In order to prevent dust and moisture pollution in the process gas, traditional online gas analysis instruments need to go through a three-step process of "sampling-pretreatment-analysis", which has complex systems, long response time, poor reliability, high maintenance costs, poor anti-interference, etc. Inherent defects cannot fully meet the requirements of real-time control of industrial processes; in addition, ...

Problems solved by technology

In order to prevent dust and moisture pollution in the process gas, traditional online gas analysis instruments need to go through a three-step process of "sampling-pretreatment-analysis", which has complex systems, long response time, poor reliability, high maintenance costs, poor anti-interference, etc. Inherent defects cannot fully meet the requirements of real-time control of industrial processes; in addition, the bases and protective devices of gas analyzers in the prior art are made of ordinary hard plastic or ordinary metal, which cannot cope with high temperature and corrosive samples during long-term work. The damage caused leads to the scrapping of the entire device, causing great losses

Moreover, the gas analyzers in the prior art are not equipped with an emergency treatment plan when objective conditions change, such as gas mixed with impurities or dangerous gas leaks, which is not only prone to erroneous data leading to heavy losses in production, but also may cause personal injury to operators
