Continuous Smoke Ultra Low Online Monitoring System CEMS

Product Introduction

Continuous Smoke Ultra Low Online Monitoring System CEMS(referred to as the system) can achieve the emission of pollutant gases (SO) from industrial pollution sources and exhaust gas outlets₂、NO、NO₂）Continuous online monitoring of smoke concentration and related smoke parameters (flow rate, temperature, pressure, oxygen content, humidity). It can achieve automatic and real-time monitoring of industrial pollution source exhaust emissions and the operation of treatment facilities, which not only facilitates enterprises to understand and grasp the specific situation of pollution control and exhaust emissions, but also facilitates the monitoring and management of environmental protection authorities, providing practical and effective regulatory means for achieving energy conservation, emission reduction, and environmental total control.

The system consists of a particulate matter monitoring subsystem and a gaseous pollutant monitoring subsystem (measuring SO)₂、NO、NO₂、 0₂）The system consists of four parts: the monitoring subsystem for smoke parameters (temperature, pressure, flow rate, humidity, etc.) and the data acquisition and processing subsystem. The gaseous pollutant monitoring subsystem adopts an extraction based cold dry method.Measurement of SO in flue gas using ultraviolet differential absorption spectroscopy₂、NO、NO₂Wait for the concentration of pollutants. Using electrochemical sensors to measure wet oxygen content, and then calculating SO through dry wet conversion₂、NO_X、 0₂Dry based smoke concentration.The particulate matter monitoring subsystem measures the concentration of smoke and dust in flue gas, and there are two configuration schemes: direct measurement method and extraction measurement method. Among them, the direct measurement method adopts laser backscatter method, which is suitable for monitoring the concentration of smoke and dust in conventional range. The extraction measurement method adopts laser forward scattering method, which is suitable for ultra-low range smoke concentration monitoring.The smoke parameter monitoring subsystem mainly measures auxiliary parameters of smoke, which are used for dry to wet basis value conversion, operating condition value standard condition value conversion, standard value conversion value conversion, and emission calculation.The data acquisition and processing subsystem is mainly used to implement functions such as data acquisition, storage, statistics, and report output for real-time on-site measurement.

Continuous Smoke Ultra Low Online Monitoring System CEMSAdopting a modular structure, the structure is simple, the dynamic scalability is strong, the operating cost is low, and it can meet the communication requirements with the internal DCS system of the enterprise and the data platform system of the environmental protection department.
