Embodiment

[0062] In order to make the above-mentioned features and advantages of the present invention clearer and easier to understand, a mechanical coke oven in Shanxi Province of my country is selected as a calculation example. The present invention can also be implemented or applied through other different specific implementation modes. The parameters in this embodiment come from on-site testing and literature research, and the specific parameters should be selected and determined based on the actual situation of the coking plant under study.

[0063] According to on-site sampling and laboratory analysis, the concentration and ratio of EC, OC and BSO in the coke oven top of the coking plant are obtained, as shown in Table 1.

[0064] Table 1 is the concentration and ratio of fugitive emission pollutants in the coking process of Shanxi Province

[0065]

[0066] The percentage of coke oven doors and covers with visible leaks in each coking plant, and the total number of all doors ...

Abstract

The invention relates to the field of atmospheric pollution control, and discloses a method for estimating coke oven top fugitive emission carbonaceous particle emission factors in the coal coking process. The method is mainly used for solving the bottleneck problem that the fugitive emission carbonaceous particle emission factors lack in the process of researching the emission quantity of coking pollutants in the prior art. The invention provides a method for estimating coking fugitive emission organic carbon and elemental carbon emission factors. The method specifically includes the first step of analysis of the ratio of organic carbon and elemental carbon in coking fugitive emission particles to BSO, the second step of emission rate estimation of BSO in the fugitive emission particles, and the third step of organic carbon and elemental carbon emission factor estimation. The method solves the problem that the emission factors lack when the coking fugitive emission carbonaceous particle emission quantity is quantitatively estimated, and has very important practical application value in further evaluating and estimating the coking fugitive emission pollution degree.

Description

technical field [0001] The invention relates to a method for estimating the emission factor of fugitive emission of carbon particles (organic carbon and elemental carbon) from the top of a mechanical coking coke oven. Background technique [0002] Atmospheric carbon aerosols are urban PM 2.5 important component of PM 2.5 The percentage of carbon is up to 40%, mainly including organic carbon (OC) and elemental carbon (EC), among which EC has strong light absorption and is also called black carbon (BC). Studies have shown that OC has a scattering effect on light, while BC has a strong ability to absorb light and heat, and is considered to be one of the main substances that cause global warming. Atmospheric circulation, the Earth's water cycle and climate change have significant impacts. In addition, due to the high physiological toxicity of certain aromatic compounds in OC, such as polycyclic aromatic hydrocarbons and dioxins, EC has a strong adsorption capacity, which can ...
