Odor gas refers to the atmosphere, water, soil, waste and other substances in the odor gas, is a class of gas collectively, through the air medium effect on the human olfactory organ perception and cause unpleasant and harmful to human health of a class of pollution gaseous pollutants. Usually refers to the odor, refers to the physical, chemical reaction process produced with the stench of the gas. Odor gas as the 1 kind of atmospheric pollutants, to people's life and health caused trouble, serious can also make people suffocate to death. The odor detector is used to detect this gas gas detector, which can detect the odor content. Then ? The following is a brief introduction by yi yun Tian:

principle of odor detector:

At a time when environmental changes are becoming more and more complex, the monitoring and treatment of odor environment has become another major environmental protection trend after garbage classification. In particular, in 2018, the state issued the Technical Specification for Environmental Monitoring of Odor Pollution (HJ 905-2017) ", more and more environmental protection enterprises began to pay attention to the odor detector.

the principle of the odor detector is to detect the types of odor generated around it to detect the odor content. for example, common sewer sewage wells detect hydrogen sulfide, garbage dumps detect hydrogen sulfide and ammonia, and chemical plants need to detect them according to specific gases.

The odor detector can simultaneously monitor nine indicators (ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, odor) specified in the Emission Standard for Odor Pollutants (GB14554-1993), optional plus PM2.5, PM10, temperature, humidity, wind speed, wind direction, atmospheric pressure, illumination, noise and other parameters.

In summary, it is the principle of the odor detector. For example, most industrial enterprises from chemical plants, garbage treatment plants, sewage treatment plants, feed plants and fertilizer processing plants, livestock product farms, leather mills, pulp mills and other industrial enterprises that use petroleum as raw materials need to use odor detection.
