Two detection methods of oxygen content in electric tar catcher
.
The two detection methods of oxygen content in the electric tar catcher are:
In-situ measurement method: This method mainly uses the laser principle. The laser emitting unit is installed on one side of the technical pipeline under test, and the receiving sensing unit is installed on the other side. This can ensure that the optical paths of the transmitting unit and the receiving unit are docked. In order to ensure the accuracy of the measurement, it is necessary to strictly ensure the installation coaxiality of the equipment, so as to carry out complex optical path adjustment work.
Extraction measurement method: This method uses a sampling probe to extract oxygen from the outside of the process pipeline, and then sends the oxygen through the pipeline to the gas purification unit for processing. The treated oxygen can enter the analytical instrument for measurement.
The above two methods have their own characteristics, and a suitable oxygen content detection method can be selected according to actual needs and working conditions. At the same time, in order to obtain more accurate measurement results, it is also necessary to pay attention to the installation, commissioning and maintenance of the equipment.
