Abstract

The invention relates to a boarding machine tail gas humidity detection device and method. The device comprises a laser driving assembly, a laser, a laser beam splitter, a to-be-detected gas chamber,a first photoelectric sensor, a second photoelectric sensor, a first pre-amplification circuit, a first band-pass filter circuit, a second pre-amplification circuit, a second band-pass filter circuitand an upper computer. Compared with zirconium dioxide chemical method measurement, the method provided by the invention is not influenced by the environment of a chemical reaction, is not influencedby the chemical reaction and the consumption of reactants, needs to replace the zirconium dioxide sensor probe every three years, has the advantages of high sensitivity, good selectivity, high response speed and the like, and can realize higher-precision measurement.

Description

technical field [0001] The invention relates to the field of gas detection and parameter detection of preventing setting machine, and more specifically relates to a device and method for detecting humidity of textile setting machine tail gas based on TDLAS (laser tunable diode absorption spectrum) technology. Background technique [0002] The humidity of the tail gas of the textile setting machine is an important parameter to control the speed of the setting machine, which is of great significance to the energy saving of the textile industry. At present, the humidity detection of the textile setting machine mainly uses a zirconia sensor to react with oxygen atoms to detect the concentration of oxygen atoms in the gas to be measured, and then calculate the concentration of water vapor. [0003] However, due to the existence of oxygen in the construction period through the oxygen atom detection, there is a large error in the detection of the water vapor concentration through t...
