Odor monitoring equipment is an instrument used to detect and monitor odorous gases, mainly used in environmental monitoring, industrial production process control and other fields. Odorous gases refer to those gases that have a strong pungent odor and cause harm to human health and the ecological environment. The application range of odor monitoring equipment is very wide, and the definition, types, principles, application scenarios, advantages and disadvantages of odor monitoring equipment will be introduced in detail below.
1. Definitions. Odor monitoring equipment is an instrument used to detect and monitor odor gases, usually consisting of sensors, data collectors, and display controllers. The device is able to detect malodorous substances in the gas in real time and quickly and transmit the data to a computer or controller for further analysis and processing.
2. Types. At present, there are many types of odor monitoring equipment on the market, mainly including: gas chromatograph, mass spectrometer, optical odor monitor, electronic nose, etc. Among them, gas chromatography and mass spectrometry are relatively traditional detection methods, which require the use of a large number of samples and solvents, and the operation is complex, which is not suitable for ** monitoring. The optical odor monitor and electronic nose can achieve real-time, fast and automatic monitoring, which is the mainstream product in the current market.
3. Principle. The principle of malodor monitoring equipment is mainly based on sensor technology and chemical analysis methods. Different types of odor** monitoring devices have different detection principles, but they can be roughly divided into the following:
1.The principle of the optical odor monitor is based on the fact that different gases absorb and scatter light differently, and calculate the concentration of a gas by measuring the degree to which the light beam is absorbed or scattered as it passes through the gas.
2.The principle of the electronic nose is to use an array of gas sensors to detect the composition of the gas by simulating a bioolfactory system, and to classify and quantify the gas through a pattern recognition algorithm.
3.The principle of a mass spectrometer is to ionize a gas into ions, and the composition and mass concentration of the gas are analyzed by measuring the mass-to-charge ratio of the ions.
4.The principle of a gas chromatograph is to separate a gas into individual components, and the composition and mass concentration of the entire gas are determined by measuring the concentration of each component.
Fourth, application scenarios.
Odor monitoring equipment is widely used in environmental monitoring, industrial production process control and other fields. In the field of environmental monitoring, it can be used to detect the odorous gas emissions of municipal waste treatment plants, sewage treatment plants, breeding farms and other places to ensure that these places meet environmental protection requirements. In the field of industrial process control, it can be used to monitor the malodorous gas generated in the production process in real time to ensure the stability and safety of the production process. In addition, odor** monitoring devices can also be used to monitor air quality in public places, such as schools, hospitals, etc., to protect people's health and comfort.
