Foreword to stench:

Stench refers to all gas substances that stimulate the olfactory organs, cause people to be unpleasant and damage the living environment. According to the emission standards of odorous pollutants, the control indicators of odorous pollutants include ammonia, trimethylamine, hydrogen sulfide, and methylthiol. , methylsulfide, dimethyl sulfur, carbon disulfide, styrene and odor concentration, the above nine substances are very harmful to the human body. At the same time, in view of the complexity of the source of stench and the interval of discharge, it is especially important to install online monitoring equipment for chemical parks, garbage treatment plants, sewage treatment plants, pharmaceutical factories, breweries, textile factories, cement factories, livestock and poultry farms and other areas that are prone to stench.

Recently, YiYuntian has installed 4 sets of stench online monitors for an environmental protection company in Guangxi, which are mainly used to monitor exhaust gas (stench) in the garbage disposal workshop and in the factory boundary. The whole set of equipment consists of a power supply unit, a sampling unit, a sample gas filtration unit, a sensor detection unit, a data processing unit, a display unit and a transmission unit. It can simultaneously monitor six gases, including foul smell, plus PM2.5, PM10, temperature, humidity, wind speed, wind direction, atmospheric pressure and other parameter indicators; industrial-grade high-precision touch screen, perfectly displays the current concentration value, built-in large-capacity storage chip, can easily store long-term data, and through special connection Export data; compatible with TCP, IP, MODBUS, DTU and other communication protocols, wireless data can be uploaded to the local environmental protection bureau, and wired long-distance network can also be transmitted.
