Smoke gas detection rod system error eliminating device in calibration process of smoke gas analysis instrument

Abstract

The invention relates to a smoke gas detection rod system error eliminating device in a calibration process of a smoke gas analysis instrument. The smoke gas detection rod system error eliminating device comprises a buffer gas cylinder, a calibration gas pipe and a pressure reducing valve, wherein the buffer gas cylinder comprises a transfer joint, a gas accommodating cavity and a second sealing threaded cover; one end of the transfer joint is fixedly connected with one end of a detection head of a smoke gas detection rod; the other end of the transfer joint extends into the gas accommodatingcavity and is fixedly connected with the gas accommodating cavity; one end, far away from the transfer joint, of the gas accommodating cavity is fixedly connected with one end of the calibration gas pipe; the second sealing threaded cover sleeves the calibration gas pipe and is connected with the gas accommodating cavity through screw threads; the other end of the calibration gas pipe is connectedwith an exhaust pipe opening of the pressure reducing valve; a smoke gas analysis instrument is connected with one end, far away from the buffer air cylinder, of the smoke gas detection rod. The smoke gas detection rod system error eliminating device has the beneficial effects that through the arrangement of the buffer gas cylinder, the smoke gas detection rod is connected into a calibration device of the smoke gas analysis instrument, so that the system error due to the adsorption effect of the smoke gas detection rod on the smoke gas can be eliminated; the calibration precision is improved.

Description

technical field [0001] The invention relates to the technical field of eliminating calibration errors of flue gas analyzers, in particular to a device for eliminating system errors of flue gas probe rods during the calibration process of flue gas analyzers. Background technique [0002] After the flue gas analyzer has been used for a long time, it is prone to deviation, resulting in inaccurate flue gas measurement and analysis results. It is necessary to calibrate the flue gas analyzer regularly to ensure the accuracy of the flue gas measurement and analysis of the flue gas analyzer. [0003] However, in the process of calibrating the flue gas analyzer with the standard gas, the flue gas probe is not connected, and the adsorption effect of the flue gas probe on the flue gas is ignored, resulting in inaccurate calibration results. Therefore, it is necessary to calibrate the flue gas analyzer A flue gas probe is added to the calibration device to eliminate the systematic error...
