Online Continuous Monitoring System for Smoke: Design and Construction of a "Turnkey" Project

CEMS (Continuous Emission Monitoring System) is an abbreviation for Continuous Emission Monitoring System. It refers to a device that continuously monitors the concentration and total emission of gaseous pollutants and particulate matter emitted by atmospheric pollution sources and transmits information in real-time to the competent department. It is called the "Automatic Emission Monitoring System", also known as the "Continuous Emission Monitoring System" or "Online Emission Monitoring System". Excellent products that comply with current Chinese or international standards, and meet relevant metrology regulations, environmental protection regulations and standards, as well as the technical requirements of the system in terms of functional design, structure, performance, installation and testing proposed by the industry.

Mainly used in continuous monitoring of industrial waste gas emission sources such as various kilns, rotary kilns, and boilers, including thermal power plants, waste incineration power plants, chemical plants, paper mills, machinery factories, foundries, non-ferrous smelting, non-metallic calcination, and other industries, it has strong applicability and can measure SO2 concentration, NOx concentration, CO concentration, CO2 concentration, particle concentration, oxygen content, temperature and humidity online Multiple gas parameters such as pressure and flow rate.

To protect the environment, environmental protection departments in various regions will formulate pollutant discharge standards suitable for each region based on the actual situation and the requirements of the State Environmental Protection Administration. For this reason, the environmental protection department will monitor the gas emissions of enterprises with fixed gas emission sources in real time. The measurement results of CEMS can be timely transmitted to the environmental monitoring platform through wireless or other means, meeting the requirements of the environmental protection department and avoiding unreasonable punishment from the environmental protection department.

Another important role of CEMS measurement results is to analyze the efficiency of desulfurization and denitrification equipment. By monitoring and comparing the flue gas composition at the inlet and outlet of desulfurization and denitrification equipment in real-time, the operation status of desulfurization and denitrification equipment can be effectively judged. At the same time, by monitoring the flow rate of imports, the total amount of SO2 and NOx entering the desulfurization and denitrification equipment can be accurately calculated, and this information can be timely transmitted to the DCS of the desulfurization and denitrification equipment to control the injection dose and improve the efficiency of the desulfurization and denitrification equipment.

CEMS

The continuous monitoring system for flue gas emissions designed and produced by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. adopts direct extraction+cold drying+ultraviolet differential spectroscopy technology. Its core gaseous pollutant analyzer adopts the ultraviolet differential absorption spectroscopy technology recommended by the National Environmental Protection Department and the United States Environmental Protection Organization (USEPA). This system is suitable for real-time online automatic monitoring of pollutant concentration and flue gas parameters during process production or exhaust emissions. The monitoring parameters include SO2, NOX, O2, particle concentration, flow rate (flow rate), temperature, pressure, etc. The application scope covers industries such as thermal power plants, cement, chemical industry, metallurgy, papermaking, as well as industrial boilers and kilns. The system has the advantages of complete real-time online measurement, stable and reliable operation, high monitoring accuracy, low operating costs, easy installation and maintenance, and no need for personnel supervision.
