Working principle of CEMS system

2025-08-06

The working principle of CEMS (Continuous Emission Monitoring System) is based on physical and chemical sensor technology, as well as data acquisition and transmission technology. Through sampling, preprocessing, analysis, data acquisition and transmission, it achieves continuous monitoring of flue gas emissions. The following is a detailed introduction to its working principle: 1、 Sampling and preprocessing Sampling: The CEMS system extracts flue gas samples from the flue through sampling probes. Sampling probes are usually equipped with ceramic or stainless steel filters to filter out dust in flue gas, preventing it from entering subsequent equipment and causing blockage and damage. Preprocessing: The extracted flue gas samples need to undergo pretreatment, including heating, transportation, filtration, and condensation steps. Heating and conveying are used to prevent condensation of water vapor in flue gas and avoid interference with subsequent analysis; Filtering is to further remove particulate matter from the flue gas; Condensation is used to lower the temperature of the flue gas for subsequent analysis. 2、 Gas analysis The preprocessed flue gas sample is sent to a gas analyzer for various component analyses, such as SO ₂, NOx, O ₂, etc. Gas analyzers use various technologies, including b...

Key points for selecting flow meters

2025-08-06

Measurement requirements: Select the appropriate type of flowmeter based on measurement accuracy requirements. Fluid characteristics: Consider the influence of fluid viscosity, density, temperature, pressure, and other characteristics on measurement results. For example, high viscosity fluids may not be suitable for using turbine flow meters or electromagnetic flow meters; Fluids containing solid particles may clog certain types of flow meters. Installation conditions: Select the appropriate type and installation method of flowmeter according to the installation environment. For example, in situations where non-contact measurement is required, ultrasonic flow meters can be chosen; In situations where space is limited, compact flow meters can be chosen. Economic factors: Considering the cost and maintenance expenses of the flowmeter while meeting measurement needs. The prices of different types and brands of flow meters vary greatly, and it is necessary to choose according to actual needs....

The core advantages of infrared gas leak detector

2025-08-06

The core advantages of infrared gas leak detectors are reflected in five aspects: non-contact remote detection, high-sensitivity visual positioning, efficient safety inspection, anti-interference adaptation to complex working conditions, quantitative leakage and preventive maintenance. The specific analysis is as follows: 1、Non contact and long-distance detection capability Infrared gas leak detectors can detect leaks from tens to hundreds of meters away, without the need to be close to high-pressure, high-temperature, or toxic gas areas (such as high-altitude pipelines and chemical plant reactors). For example, the Hanwei R10 handheld detector can detect distances up to 20 meters, and the T-800 airborne system can achieve large-scale rapid screening through unmanned aerial vehicles, avoiding direct contact with hazardous environments and significantly improving safety. 2、High sensitivity and visual positioning The device can detect trace leaks at PPB level (one billionth) or PPM level (one millionth), and visually display the gas plume morphology and diffusion direction through thermal imaging. For example, the LUFT300 VOC gas infrared leak detector uses a type II superlattice cooling detector, which can locate small VOC leakage points in real time; The Fujirui infrared leak detector uses a 320...

Analysis of problems, countermeasures, and suggestions for industrial VOCs control!

2025-08-08

Abstract Under the concept of sustainable development, China has further increased its efforts to control natural environmental pollution. VOCs are common volatile organic compounds that are often produced in industrial production. From the perspective of physical and chemical properties, VOCs themselves have strong toxicity, as well as strong mobility and pollution, posing significant hazards to human health and the natural environment. This requires attention to the treatment of VOCs pollution in industrial production. However, due to various factors, the effectiveness of industrial VOCs pollution control in China is not ideal, especially under a single pollution control method, it is difficult to quickly adsorb harmful substances in exhaust gas and achieve clean pollution control. A study shows that in China, nearly half of the cities have industrial VOCs exceeding level two, which causes significant pollution to the urban environment and seriously damages people's physical and mental health. Based on this, it is necessary to further optimize VOCs pollution control methods. Characteristics and hazards of VOCs pollution from industrial sources 1. Characteristics of VOCs pollution from industrial sources As an organic compound, VOCs themselves have strong toxicity and pollut...
