Application of Formaldehyde Sensor in Monitoring the Emission of Malodorous Pollutants in Industrial Enterprises
In recent years, there have been more and more conflicts between residents and businesses due to malodorous emissions, and residents’ complaints have become more frequent. Environmental remediation, especially odor remediation, has become an important project involving social stability and harmony. The timeliness and uncertainty of odor emissions have made it difficult for environmental protection agencies to obtain evidence and enforce laws. Therefore, it is urgent to establish a real-time, high-efficiency, and rapid online monitoring system for malodorous gas to monitor the odor emission situation continuously for 24 hours. Odor pollution is a kind of perceptual (olfactory) pollution formed by natural decay in the atmosphere, water, solid waste and other substances, which is transmitted through the air medium and acts on human olfactory thinking. Except for hydrogen sulfide and ammonia, most of the malodorous substances are organic and volatile organic compounds, so it is very important for the management of malodorous gases in life. However, there are certain difficulties in the management of malodorous odors:On the one hand, the distinctive feature of malodorous pollution is that there are many sources of malodorous pollution, a wide range of pollution, and many industries involved. The concentration of malodorous substances is generally low, and can even reach the concentration of PPb. The composition of malodorous gas is more complex, and it is often a mixture of multiple malodorous substances. It is difficult to monitor and analyze odor pollution, and it is more difficult to control odor than general air pollution. On the other hand, the old detection method is to send manual inspections, and the threshold of malodorous substances is generally low. The traditional malodor detection is carried out by nationally recognized sniffers, who mainly use their noses to detect the smell. The odor of eggs, mildew, dung odor and even abnormal scents are distinguished, and the odor level is determined to confirm whether it is within the prescribed odor emission standards. However, this traditional method has great limitations. It is time-consuming, labor-intensive, and subject to human subjective influence. At the same time, because the human nose is passivated during olfaction, it is impossible to detect a large number of samples. If you stay in an environment with a high malodor concentration for a long time, the human olfactory nerves will begin to paralyze the senses, leading to inaccurate judgments, and this method also has a certain impact on the health of inspectors. Therefore, the sensor plays an important role in the malodorous environment monitoring system. In response to this situation, the editor recommends formaldehyde transmitters. The formaldehyde transmitters use electrochemical sensors, which have the characteristics of high measurement accuracy, fast response, long service life, long stability and reliability, and device output resolution. It can be up to 0.01ppm and can be monitored online for 24 hours for a long time, which can meet the monitoring of formaldehyde concentration by industrial enterprises. It is mainly used in industries or equipment that require long-term online monitoring of formaldehyde concentration, such as smart homes, air cleaners, and air conditioners. The equipment adopts wide-voltage 10~30V DC power supply, analog signal output, 4~20mA, 0~5V, 0~10V optional, and the outer shell has a high protection level, which can adapt to the harsh environment of the site. Features:1. Range 0-5ppm, other ranges can also be customized. 2. The measurement accuracy is high, and the repeatability can reach within 2%. 3.485 Communication interface standard ModBus-RTU communication protocol, address and baud rate can be set, the communication distance is up to 2000 meters. 4. Optional high-quality OLED display, the value can be viewed directly on site, and can be displayed clearly at night. 5. The on-site power supply adopts 10~30V DC wide-voltage power supply, which can adapt to a variety of on-site DC power supplies. 6. It adopts wall-mounted waterproof shell, which is easy to install and has a high degree of protection, which can be used in harsh on-site environments.
