What is the difference between organized exhaust gas and unorganized exhaust gas?

Fugitive emissions refer to the irregular emission of air pollutants without passing through the exhaust cylinder. The emission of low exhaust pipes is an organized emission, but under certain conditions, it can also cause the same consequences as unorganized emissions. Therefore, when implementing the "fugitive emission monitoring concentration limit" index, the increase in pollutant concentration at the monitoring point caused by the low exhaust cylinder will not be deducted.

GB16297-1996 Air Pollutants Comprehensive Emission Standard) usually includes non-point sources, line sources and point sources. For example, coal, clay, limestone, and loose objects on the surface of paint parts stacked in the open air are all unorganized emissions from non-point sources; When the car is driving on the road with loose materials, the emission of dust pollutants from the coil is a linear source pollution; The amount of dust generated by bulk materials in the automobile loading machinery and the dust pollution emission during automobile unloading are all point unorganized emission sources.

The composition of pollutants in exhaust gases is complex, and the types of exhaust gases are very different, as well as different toxicity. Taizhou Environmental Testing Center is to track the changes in environmental quality, determine the level of environmental quality, and provide the basis and guarantee for environmental management and pollution control through the detection of the content and emissions of various substances that affect human beings and the environment. To put it simply, understanding the environmental level and carrying out environmental monitoring is the premise of all environmental work.

The industry also has strict guidelines for the emission of exhaust gases, which are divided into organized emissions and fugitive emissions, so the methods of waste gas treatment (chǔ lǐ) are also different for different emission methods. The following is a professional environmental monitoring manufacturer to intelligently answer the difference between organized and unorganized emissions of exhaust gas.

Organized emission, that is, the regular concentrated discharge of air pollutants through the exhaust cylinder. Almost all of the exhaust gases emitted in this form are produced by industrial production, and after treatment, the emission concentration is low, and it is discharged to the air with relatively easy diffusion.

Fugitive emission refers to the leakage of no closed equipment or imperfect sealing measures in the production process, and the exhaust gas does not pass through the exhaust cylinder or chimney, and the infected substances are directly discharged to the environment, or diffuse from the open work site, waste dumping site, etc. Fugitive emission is an important way for VOCs to enter the atmospheric environment, and the exhaust gas of fugitive emission accumulates over time, and the harm to the environment cannot be ignored.

At present, organized emissions can reduce pollution to the environment through (tōng guò) waste gas treatment (chǔ lǐ) devices, while unorganized emissions are difficult to quantify and treat due to the characteristics of many types of pollutants, wide emission points, etc., and there are many process factors and environmental factors that affect unorganized emissions, so it is difficult to determine the amount of emissions and emission laws, so it is difficult to monitor, evaluate and control, which is one of the difficulties that need to be solved in exhaust emission control.

To explain it simply, it is as follows:

Unorganized: There is no exhaust pipe or the height of the exhaust pipe is less than 15m

Organized: There is collection, processing and the exhaust pipe is higher than 15m is called organized.

1. Different ways of emission: organized emission refers to the centralized treatment of air pollutants after passing through a specific exhaust place; The fugitive emission of Zhichang refers to the air pollutants that are randomly produced in life or production without organization.

2. The degree of treatment of pollutants is different: the emission concentration of air pollutants treated by organized emission is low and the diffusion is faster; The concentration of air pollutants emitted by unorganized emissions is higher and the diffusion is slower.

3. The pollution to the environment is different: the organized emission has been specially treated, so the degree of pollution to the environment is smaller; Fugitive emissions, on the other hand, have no specific management, so they pollute the environment to a greater extent.

Organized emissions and fugitive emissions refer to the two ways in which air pollutants are treated. Organized emissions are relatively easy to treat pollutants by passing them through specific exhaust outlets and then discharging them in a regular manner. Fugitive emission refers to the irregular discharge of pollutants into the atmosphere, which is not only harmful to the environment, but also difficult to control.

There are two types of emissions, one is organized emissions and the other is unorganized emissions, and fugitive emissions are exhaust gases.

Refers to emissions that do not pass through the exhaust cylinder.

Hope to adopt, thank you.

In the technical rules for environmental impact assessment, it should be that the chimney should be less than 15m

It depends on whether there is a special exhaust pipe after the erection of the shed, and if so, it is organized discharge. In addition, the collection efficiency cannot be 100% large, so there is no organization and mold.
