Detailed description

1. Overview

The TR-9300E continuous monitoring system for solid waste incineration flue gas emissions is a dedicated monitoring system for solid waste incineration flue gas, which combines the world's advanced Fourier transform infrared analysis (FT-IR), a broad-spectrum analysis technology based on infrared absorption principle, with Chinese environmental monitoring technology. Through years of accumulated experience in the industrial process field, our company has carefully crafted it. This system complies with the environmental protection industry standards of the People's Republic of China (HJ/T75-2017, HJ/T76-2017), as well as the pollution control standards for household waste incineration (GB18485-2014) and other relevant standards.

This system is applied to the online monitoring of gaseous pollutants (SO2/NO/NO2/CO/CO2/HCL/HF/NH3/O2) and solid pollutant dust, as well as temperature, pressure, humidity, and flow rate in flue gas such as waste treatment plants, waste incinerators, and continuous monitoring of flue gas emissions. Through the data collection and processing system, graphs and environmental protection reports are generated, and the data can be remotely transmitted to various levels of environmental protection departments to meet the functional requirements of receiving, storing, displaying, and transmitting monitoring data.

 

2. Monitoring plan for gaseous pollution factors

The TR-9300E solid waste incineration flue gas emission continuous monitoring system adopts the American MKS Fourier transform infrared analysis method, which is accurate in measurement, short in response time, fast in detection method, and diverse in measurement component types; The system adopts the principle of full process high-temperature (above 190 ℃) extraction analysis, which means that the flue gas is extracted through high-temperature heating rods and high-temperature probes, filtered dust, and then enters the high-temperature gas transmission pipeline. After being pretreated by the high-temperature pretreatment module, it enters the high-temperature multi-component infrared analyzer for measurement. The temperature of the analysis chamber can withstand high-temperature heating methods above 190 ℃. There is no condensation or dehumidification in the middle, and there is no condensation or dehydration device in the sampling pipeline from the sampling point to the instrument host and detection device. Advanced high-temperature measurement methods can accurately measure some special components, such as HF, HCl, NH3, and flue gas humidity that are highly soluble in water, perfectly solving the monitoring needs of complex working conditions such as high humidity, high corrosion, high dust, high temperature, low gas content, and multiple detection types in industries such as waste incineration.

 

3. Composition of gaseous pollutant monitoring system

The gaseous pollutant monitoring system consists of a high-temperature sampling unit (including a sampling probe and an integrated sampling tube), a backflow unit, a preprocessing unit, a Fourier transform infrared analysis unit, a zirconia analysis unit, a control unit, a calibration unit, and a data processing unit. The direct extraction high-temperature sampling method is used to complete the requirements for monitoring flue gas components.

 

4. System technical characteristics

• The system is produced according to industrial instrument standards and also complies with environmental instrument standards, making it highly adaptable and reliable for monitoring pollution sources.

• Adopting high-precision ceramic filter elements to overcome blockage issues to the maximum extent and reduce maintenance workload.

• Adopting full process high-temperature sampling, high-temperature pretreatment, and high-temperature analysis, the temperature can reach 190 ° C or above, ensuring no condensation during the monitoring process.

• The sampling pipeline adopts a cluster of Teflon (polytetrafluoroethylene) pipes that do not require replacement, with automatic temperature control design to accurately ensure the heat tracing temperature.

• A long-term reliable and stable analysis and pretreatment device that meets the long-term stable and normal operation of the system without the need for daily maintenance.

• The analytical instrument adopts the Fourier transform infrared spectroscopy analyzer imported from MKS in the United States, which can analyze samples containing up to 40% water vapor, and can simultaneously analyze and display up to 30 gases.

• Adopting PLC control, it has a high degree of automation and low maintenance workload.

• Modular system structure design, flexible configuration; The system is easy to operate and maintain.

• The system has a long service life and is stable and reliable.
