Study on Fugitive Dust Control Technologies of Agricultural Harvesting Machinery

Abstract

The fugitive dust generated by agricultural harvesting machinery not only causes harm to production safety, but also affects the living environment of people in agricultural areas. This is also one of the hot issues that have emerged in the green development of rural areas in recent years, which is related to agricultural safety and hygiene culture. Due to the lack of relevant research, many researchers still have considerable controversy on the issue of agricultural dust. Therefore, in combination with the actual production of agricultural mechanization, according to the cause of dust generation and particle characteristics, the selection of appropriate dust reduction technology and detection methods is of great significance for the research on the control of dust from agricultural harvesting machinery. Aiming at the dust problem in agricultural mechanization production, this research first introduces the relationship between fugitive dust and atmospheric particulate matter and the main components of fugitive dust, and then focuses on the causes of dust generated by wheat harvesters and peanut harvesters in field operations, and explains the main hazards of dust to human health, ecological environment, and climate. This study introduces four fugitive dust emission reduction technologies and five particle measurement methods, and compares and analyzes their feasibility in the application of agricultural harvesting machinery dust control. Finally, we put forward conclusions and suggestions on the dust control technology of agricultural harvesting machinery in order to provide reference for the control of agricultural harvesting machinery dust, improve the field operation environment, and promote the green development of modern agriculture.

Development of a Spatial Tier 2 Emission Inventory for Agricultural Tractors by Combining Two Large-Scale Datasets

“…Emission reduction technologies, such as diesel particle filters, NO X adsorbers, selective catalytic reduction, oxidation catalysts and gasoline particle filters, offer solutions aimed at reducing emissions from agricultural tractors [30]. Considering fugitive dust emissions, the light scattering device could be a cost-friendly way of achieving lower dust emissions during fieldwork [31]. Hybrid technologies and electricity as new propulsion technologies are necessary for achieving climate neutrality in the agricultural sector [32,33].…”

“…Hu et al [22] presented a numerical simulation method to study dust dispersion characteristics and dust control measures during continuous dusting and dusting periods. Liu et al [23] studied fugitive dust control technologies for agricultural harvester machinery and presented four fugitive dust emission reduction technologies and five particle measurement methods. Chen et al [24] explored the dust removal performance of a newly structured microporous membrane filter plate through experiments.…”
