1. Product Background:

In recent years, there have been increasing conflicts between residents and businesses due to odor emissions, and residents have been petitioning more frequently. Environmental remediation, especially odor control, has become an important project involving social stability and harmony. The timeliness and uncertainty of odor emissions have made it difficult for environmental protection departments to obtain evidence and enforce laws. Therefore, there is an urgent need to establish a real-time, efficient, and fast odor automatic monitoring system to monitor the odor situation24-hour continuous monitoring.

Odor refers to any gas substance that stimulates the sense of smell and causes discomfort and damage to the living environment. Odor concentration is a comprehensive characterization factor of air quality, and its value is a comprehensive reflection of mixed air quality. There are various sources of odor, and the composition of odor is complex. Therefore, a comprehensive indicator is needed to limit it. China's method of limiting odor is based on the national "Emission Standards for Odor Pollutants"（GB 14554-93）， The limit value for odor concentration in the factory environment is set at 20OU.

At present, odor monitoring adopts the national standard analysis method "three-point comparative olfactory bag method (GB/T14675-93)", which is a testing method based on human olfactory senses. The sampling and analysis process relies entirely on manual operation, resulting in extremely heavy tasks for detection personnel. When conducting odor identification analysis, there are many restrictive conditions for detection personnel, and there are a series of problems such as low work efficiency, poor timeliness, poor objectivity of data, and high labor costs. Therefore, it is imperative to build an automatic online monitoring system for pollution source odors.

2. Product Introduction:

OsenOSEN-OU Odoron-line monitoring systemAccording to the current odor detection standards in China, the "Emission Standards for Odor PollutantsGB14554-93 "and" Three point Comparative Stinky Bag Method GB/T 14675-93 "are used to correlate the detection results with human olfaction, and a multi-channel point by point sampling system (manifold system) is used for simultaneous detection of adsorption and detachment，The monitoring parameters mainly include odor concentration（The concentration of OU, H2S, NH3, and TVOCs is detected by the system in accordance with national standards. In addition to detecting single gas and compound odor concentrations of 8 gas substances in 3 major categories (S series, N series, VOCs series), the reactive substances of the semiconductor sensor can be extended to detect about 22 odors that can be smelled by humans (VFAs series, Aldehyde series). systemmainanswerused forGovernment environmental monitoring department，There is air pollution presentofEnterprises include: technology parks, chemical parks, waste treatment plants, sewage treatment plantsPharmaceutical factories, breweries, energy and power companies, textile factories, urban and rural residential areasreachResearch institutes and universitiesWaiting for places.

（1) The integration of odor sensors and cleaning devices extends the lifespan of the sensors, greatly stabilizing the output signal and improving the reliability of odor concentration detection results;

（2) Sampling core source technology - sensor output signal analysis technology is used to convert gas concentration. Odor is detected using metal oxide semiconductor gas sensors, with results displayed in dilution multiples (OU). Hydrogen sulfide and ammonia are detected using electrochemical gas sensors, with results displayed in ppm. VOCs are detected using photoionization gas sensors, with results displayed in ppm;

（3) Up to 20 sensors can be expanded according to demand;

（4) The louvered box type odor inhalation structure ensures the stability of odor inhalation;

（5) Equipped with a long-life vibrating armature pump, the sampling speed of the injection pump is 0.5L/min, and the flow rate is automatically controlled;

（6) Built in 10.2-inch large screen high-performance embedded computer (IEC667-07), real-time display of test results on site, and the ability to set and modify various parameters on site through the WINCE screen;

（7) Support LAN (TCP/IP wired communication), GSM or CDMA wireless data communication to transmit data;

（8) After a power outage, there is an automatic repair function to protect monitoring data in real-time from loss;

（9) Built in automatic temperature adjustment device, lightning protection device, and surge protection device;

（10) An expandable odor automatic capture device (automatic sample retention system) can be installed for odor collection, and an expandable meteorological monitoring system can be used to monitor wind direction, wind speed, temperature, humidity, air pressure, etc.
