cems on-line smoke monitoring system solutions to common problems

　　The on-line monitoring system for cems flue gas is a continuous automatic monitoring of the concentration of particulate matter and gaseous pollutants from fixed sources and the total emissions of pollutants using specific instruments, while related environmental equipment, such as desulphurization and denitration, relies on the on-line monitoring and management of cems flue gas to achieve pollution control.

　　cems on-line smoke monitoring system It consists of four main components of the gaseous pollutant detection subsystem, the flue gas parameters monitoring subsystem and the particulate matter detection subsystem, data collection and treatment subsystem. The gaseous pollutants monitored by the fire power industry are usually sulfur dioxide and nitrogen oxides, sulfur dioxide and nitrogen oxides floating in the air, creating a range of environmental problems. Monitoring emissions from sources of pollution is a source of data and foundation for environmental protection and an important basis for measuring environmental pollution levels and controlling pollution.

　　(1) Sampling system blocked

　　Blockage of sampling systems is a common problem in the cems flue gas online monitoring system, which mainly refers to sampling probe, sampling tube or filter core congestion, which destabilizes the data of the cems flue gas online monitoring system and thus does not serve as a standard for flue gas control. The above-mentioned problems are prone to high parameters, and if congestion in the sampling system occurs, it will have a real impact on pollution measurement efforts. Therefore, in practice, attention will have to be paid to conducting regular checks of filter cores, sampling probes and anti-blowing systems to ensure that each part of the system works well.

　　Method of detection: Analysis of differences in the speed of the flue flow, observation of the smoothness of the sampling system before and after the pump and rationalization of management.

　　(2) Leakage of the sampling system

　　The reason for the leakage of the data sampling system is the collapse of the pressure system, which is an important element in ensuring the normal operation of the cems' on-line monitoring system, the observation of pre- and post-pump pressure and the ability to measure the leakage of the cems' on-line monitoring system in conjunction with changes in the flue flow.

　　Method of detection: The system removes the pneumatic pneumatic pipe from the sample analysis state, blocking the import of the pneumatic gas, if the sample flow meter cannot be reduced to 0L/min within a period of about one minute, indicates a leak point in the airlock of the system, removes any possible leakage points, and ensures that the cems pneumatic online monitoring system is back to normal in a timely manner.

　　(3) Liquid water from sampling pipelines

　　The main reason for the occurrence of liquid water is the failure of the heating system, which, if broken, will result in the failure of the online monitoring system and will seriously affect the accuracy of the measurements, causing some difficulty in subsequent pollution control efforts.

　　Methodological measures: The analyzer will be preceded by the installation of a water-resistant gas-ream and spot protection to prevent serious malfunctions in the core parts of the analyzer.
