Problems solved by technology

For the existing exhaust gas, under normal circumstances, we only sample the flue gas at a point, and the concentration value at this point represents the concentration data of the entire interface. However, due to the different sizes of the current flue ducts, some areas are very large. The equivalent value of the flue gas is very large, and the gas concentration in the flue gas is difficult to be uniform, which eventually leads to further amplification of the data deviation; at the same time, the suspended matter in the flue gas is inhaled into the analyzer, which will also affect the analysis results of the instrument

Abstract

The invention discloses a gas analysis instrument capable of measuring equivalent concentration, which belongs to the technical field of gas analyzers. A gas analysis instrument capable of measuring equivalent concentration, comprising an instrument main body, a gas analysis system is arranged inside the instrument main body, an air inlet pipe is connected to the outside of the instrument main body, a rotating block is rotatably connected to the air inlet pipe, and a first filter screen is arranged inside the rotating block , there is a movable groove in the rotating block, a sealing backing plate is arranged in the movable groove, and the sealing backing plate moves against the first filter screen plate, and a slideway for the sliding of the first filter screen plate is opened in the rotating block, and the upper air intake pipe It is fixed with a sealed shell; the invention has the function of measuring the equivalent concentration, and can directly obtain the equivalent concentration data of the gas after obtaining the equivalent and measuring point flow data, and at the same time filter the impurities in the flue gas through the filter plate, and can automatically The filter plate in the intake pipe is replaced to avoid affecting the gas collection effect, thereby ensuring the practicability and accuracy of gas analysis and detection.

Description

technical field [0001] The invention relates to the technical field of gas analyzers, in particular to a gas analyzer capable of measuring equivalent concentration. Background technique [0002] In many production processes, especially in the production process of chemical reactions, it is often not enough to automatically control physical parameters such as temperature, pressure, and flow rate. There are many types of instruments, commonly used thermal conductivity gas analyzers, electrochemical gas analyzers and infrared absorption analyzers. [0003] The detection of gas components by the current gas analyzers only detects the concentration values ​​of various components of the gas. For the existing exhaust gas, usually, we only sample the flue gas at a point, and the concentration value at this point represents the concentration data of the entire interface. However, due to the different sizes of the current flue flue, some areas are very large. The equivalent value of...
