KR-20260063435-A - SYSTEM AND METHOD FOR SELECTING POLLUTANT EMISSION SOURCE

Abstract

The present invention aims to provide a pollutant emission source candidate screening system and method that can be utilized in workplaces and industrial complexes by automatically determining the cause of air pollution and reducing the time required to identify the cause of pollution. The pollutant emission source candidate screening system of the present invention may include a weather measurement unit having at least one weather measurement station that measures weather in a pre-set management area, a monitoring unit having at least one monitoring station that monitors air pollution in the management area, and a server that screens emission source candidates by tracing back the path of pollutant movement in the management area based on weather data from the weather measurement unit and air pollution data from the monitoring unit.

Description

System and Method for Selecting Pollutant Emission Source Candidates The present invention relates to a system and method for screening candidate pollutant emission sources. Generally, the purpose is to remove particulate and gaseous pollutants emitted from artificial activities such as industrial activities and daily life. Particulate pollutants include smog, dust, fly ash, fog, fumes, and smoke, while gaseous pollutants include livestock manure gas, plant gas, and odors. Currently, pollution control technologies used in industrial complex factories include packed towers and spray towers. Although these utilize packing materials and water, the emitted gases are visible, and problems arise regarding liquid dispersion if gas leaks or spray nozzles become clogged. Furthermore, there are many areas where gaseous pollutants emitted from livestock fertilizer plants and livestock barns are vented directly without pollution control technology, resulting in air pollution. FIG. 1 is a schematic diagram of a pollutant emission source candidate screening system according to one embodiment of the present invention. FIG. 2 is a schematic flowchart of a method for identifying a pollutant emission source according to one embodiment of the present invention. FIGS. 3 to 6 are drawings for identifying a pollutant emission source of a pollutant emission source candidate screening system and method according to an embodiment of the present invention. FIG. 7 is a diagram illustrating an exemplary computing environment in which a pollutant emission source candidate screening system and method according to one embodiment of the present invention can be implemented. Preferred embodiments of the present invention will be described below with reference to the attached drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. In addition, embodiments of the present invention are provided to more fully explain the present invention to those with average knowledge in the relevant technical field. In drawings, the shapes and sizes of elements may be exaggerated for clearer explanation. In describing the embodiments of the present invention, if it is determined that a detailed description of known technology related to the present invention may unnecessarily obscure the essence of the present invention, such detailed description will be omitted. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intentions or conventions of the user or operator. Therefore, such definitions should be based on the content throughout this specification.
