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, and belongs to the technical field of gas analyzers. A gas analysis instrument capable of measuring equivalent concentration comprises an instrument body, a gas analysis system is arranged in the instrument body, a gas inlet pipe is externally connected to the instrument body, a rotating block is rotationally connected to the interior of the gas inlet pipe, a first filter screen plate is arranged in the rotating block, a movable groove is formed in the rotating block, and a sealing base plate is arranged in the movable groove. The sealing base plate movably abuts against the first filter screen plate, a sliding way used for sliding of the first filter screen plate is formed in the rotating block, and a sealing shell is fixedly arranged on the air inlet pipe. The device has an equivalent concentration measuring function, equivalent concentration data of gas can be directly obtained after equivalent and measuring point flow data are obtained, impurities in flue gas are filtered through the filter screen plate, the filter screen plate in the gas inlet pipe can be automatically replaced, the gas collecting effect is prevented from being affected, and the device is convenient to use and popularize. Therefore, the practicability and the accuracy of gas analysis and detection are ensured.

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, automatic control based on physical parameters such as temperature, pressure, and flow is often not enough. Due to the wide variety of analyzed gases and the variety of analysis principles, gas analysis There are many types of instruments, commonly used are thermal conductivity gas analyzers, electrochemical gas analyzers and infrared absorption analyzers. [0003] The current gas analyzers only detect the concentration values ​​of various component gases in the detection of gas components. 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,...
