Abstract
A method for identifying and eliminating ammonium salt deposition characteristics in a pipe of a hydrogenation air cooler is provided. A multiphase flow medium enters an inlet pipe box of a hydrogenation air cooler; an initial service state is calibrated, an initial temperature calibration line and an equivalent temperature reference line are drawn to set a benchmark; cross sections and temperature transmitters are arranged on a pipe bundle of the air cooler at equal intervals in the axial direction; a temperature signal value is monitored and transmitted to a single-chip microcomputer for data analysis; an infrared thermal imager performs photographing, transmits data to determine if an ammonium salt deposition risk is present under this working condition; a monitored temperature value is calculated, an ammonium salt deposition risk identification model is established, and an ammonium salt deposition risk on a temperature information monitoring section is then determined.
