Odor Preface

Odor refers to all gaseous substances that stimulate the olfactory organs, cause unpleasantness and damage the living environment. According to the emission standards of odor pollutants, the control indicators of odor pollutants include ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, and dimethyl sulfide. The concentration of disulfide, carbon disulfide, styrene and odor, the above nine substances are very harmful to the human body. At the same time, in view of the complexity of the source of malodor and the characteristics of the interval between discharges, the chemical parks, garbage treatment plants, sewage treatment plants, pharmaceutical factories, breweries, textile factories, cement plants, livestock and poultry farms that are prone to produce malodors are targeted. In areas, the installation of online monitoring equipment is particularly important.

 

Recently, Yiyuntian installed 4 sets of odor online monitors for an environmental protection company in Guangxi, which are mainly used to monitor waste gas (odor) in garbage disposal workshops and plant boundaries. The whole set of equipment consists of a power supply unit, a sampling unit, a sample gas filter unit, a sensor detection unit, a data processing unit, a display unit and a transmission unit. Simultaneous monitoring of six kinds of gases including malodor, plus PM2.5, PM10, temperature, humidity, wind speed, wind direction, atmospheric pressure and other parameters; industrial-grade high-precision touch screen, perfect display of current concentration value, built-in large-capacity storage The chip can easily store long-term data and export data through a dedicated interface; compatible with communication protocols such as TCP, IP, MODBUS, DTU, etc., wireless data upload and docking with local environmental protection bureaus can also be used for wired remote transmission networking.
