Ammonia escape ammonia online monitoring system

1、 Product Introduction

Integrated online monitoring system for denitrification ammonia escape（TK-1100The type is composed ofShandong Xinze Instrument Co., LtdProduced by the company's honor, in order to prevent the waste of funds and environmental pollution caused by the escape of ammonia gas; Ammonia escape will corrode the catalyst module, causing catalyst deactivation (i.e. failure) and blockage, greatly shortening the catalyst life; The escaping ammonia gas will mix with the airSO3Generate ammonium sulfate (corrosive and adhesive) to block and corrode the thermal storage components of the air preheater located downstream of the stripping process; Developed due to hazards such as excessive escape of ammonia being absorbed by fly ash, resulting in the inability to sell aerated blocks (ash bricks);

2、 System advantages

Due to harsh working conditions, the sample gas contains a large amount of dust and saturated water vapor. Therefore, we adopt the current xianjin methodofTK-1100Laser gas analyzer (based onTDLASTechnical analysis of trace amountsNH3The system (including the measuring cell) adopts full process heating to ensure the temperature of the sample gas and prevent water from precipitating and affecting itNH3The large amount of dissolution affects the analysis results. The probe adopts an electrically heated filtering probe, which completes the purification of the sample upon sampling, reducing the load of post-processing and greatly reducing the failure rate of the device. The system design includes a probe automatic blowback program and an instrument automatic zero calibration program, which only require normal inspection after normal operation. The transmission pipeline is customized230High temperature composite electric heat tracing cable above ℃, and controlled within2mWithin (ensuring as little as possible)NH3Adsorption), the entire pretreatment is integrated into a high-temperature heating box, and the system is compact to avoid long-distance transmission pipelinesNH3The adsorption.

3、 System features

Ammonia escape online monitoringThe main features are as followstechnical advantage：

Reliable long path heating chamber design, with a path length of up to3rice

Ultra low concentration measurement, with a resolution of up to0.1ppm

Special multi line spectral scanning algorithm, dynamic compensation for dust and moisture interference

Calibration free design, easy maintenance, low usage cost

sampling probe

The sampling probe is used for sampling the sample gas in this system and has the functions of dust filtration and heat tracing, which can effectively prevent the condensation of the collected sample gas. The structural design of * makes the sampling system more reliable, reduces the loss rate of sample gas, and ensures the stability and authenticity of the analysis system.
