LZ-ZQNXH-2000 On-line monitoring system for the extraction of ammonia escape NH3, HCI, CI2, HF analyzer

LZ-ZQNXH-2000 On-line monitoring system for the extraction of ammonia escape NH3, HCI, CI2, HF analyzer Brief introduction

The on-line monitoring system (LZ-ZQNXH-2000) for the extraction of ammonia escape () includes the pretreatment system, gas analyzer, and data processing and display. The system installation method for the in situ high temperature heat tracing. The basic principle of this system is based on tunable diode laser absorption spectroscopy (TDLAS) technology, which has the characteristics of convenient installation, high measuring accuracy, good reliability, fast response, strong anti-interference ability, etc.. Gas analysis system is especially suitable for many industrial field emission monitoring and process control, such as coal-fired power plants, aluminum plants, steel plants, garbage power plant, cement factory and chemical factory.

Features

High temperature sampling measurement is used to eliminate the influence factors, such as dust, moisture, and ensure the accuracy and stability of the measurement.

Near infrared tunable laser was used to emit a single line spectrum of the absorption wavelength of the gas, which can avoid the interference of background gas.

Using 2 m fixed absorption pool, compared to the reentry pool, more stable, more convenient adjustment.

Compared to the direct detection of ammonia escape system, the probability of the shot pollution is reduced, and the maintenance workload is reduced.

Compared with the direct detection of ammonia escape system, it can be used to test the accuracy of the system, and it can effectively avoid the problem of direct measurement.

Using direct absorption absolute measurement method, the system built in standard NH3 reference module, real-time dynamic calibration of the whole system, the system is running very little signal drift, so the whole system without user to do any regular calibration.

The instrument itself does not need to use a standard gas to carry on the adjustment to the instrument, only in situ monitoring optical side window lens is dust pollution after a simple wipe can be.

Automatic calibration of the instrument can be used to enhance the reliability of the data;

Automatic alarm and recording function with abnormal condition such as fault, power failure and detection data;

Touch screen display, the operation is simple and convenient, the interface is friendly.
