Total amount control system and method of volatile organic pollutants

Abstract

The invention provides a system and method for controlling the total amount of volatile organic pollutants. The system includes a data acquisition module and a data processing module; the data acquisition module is connected with the data processing module, and is used to obtain the organized discharge of volatile organic pollutants by enterprises , the corresponding organized emission data, and the corresponding electricity consumption data of production equipment when the enterprise discharges volatile organic pollutants in an unorganized manner, and send the organized emission data and electricity consumption data to the data processing module; data processing The module receives organized emission data and electricity consumption data, and calculates the total amount of volatile organic pollutants produced by the enterprise based on the organized emission data and electricity consumption data; The gap in technology has broken through technical barriers and responded to the trend of refinement of total control in the field of environmental protection in my country. It is a strong support for the post-permit management of sewage discharge permits in my country.

Description

technical field [0001] The invention belongs to the field of volatile organic pollutant management, in particular to a system and method for controlling the total amount of volatile organic pollutants. Background technique [0002] Volatile Organic Compounds (VOCs for short), according to the definition of the World Health Organization (WHO), VOCs are various organic compounds with a boiling point of 50°C to 260°C at room temperature. In China, VOCs refers to Organic compounds with a saturated vapor pressure greater than 70Pa and a boiling point below 260°C under normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10Pa and volatile at 20°C, VOCs are toxic, odorous, and the concentration exceeds the standard Afterwards, it will cause serious harm to people's physical and mental health. Therefore, the management of VOCs emissions is particularly important. In recent years, with the rapid and diversified development of China's social economy...

AI Technical Summary

Problems solved by technology

[0003] One is: At present, the management of the total amount of volatile organic pollutants in my country is still at a relatively macro level, and there is a lack of refined management. It is impossible to control and grasp the real-time cumulative emissions of enterprises in real time. The current supervision method mainly relies on self-certification and law-abiding by enterprises. Secondly, when enterprises apply for pollutant discharge permits, they cannot make full use of their own permits.

[0004] The second is: the technical barriers to the total control of volatile organic pollutants are relatively high, especially the fugitive emissions of VOCs. In 2019, the Ministry of Ecology and Environment specially issued the "Volatile Organic Compounds Fugitive Emission Control Standard" for the fugitive emissions of volatile organic compounds. (GB37822—2019) put forward relevant control requirements. The total amount of VOCs is different from nitrogen oxides and sulfur dioxide. Most of nitrogen oxides and sulfur dioxide are organized emissions. Complicated, excluding organized emissions, there are also a large number of unorganized emissions of source items, each emission source item is different, and the calculation method of this part of emissions is relatively complicated
