Tecnologia alternativa para o controle da poluição atmosferica em moega simples de recepção

Abstract

Agricultural activities also generates environmental impacts throughout all stages of the production process. One such impact is the emission of particulate matter during the handling of bulk products, especially during reception and storage operations. These emissions can affect air quality, worker health, and operational efficiency, highlighting the need for technological innovations focused on the control and treatment of particulate matter. This study aims to develop a technology applicable to the echnologi particulate matter emissions during grain unloading operations in simple receiving pits. The research was conducted using scientific databases such as Web of Science and Scopus (Elsevier), as well as national (INPI) and international (WIPO and Espacenet) echnol databases, in order to identify equipment for the treatment and echnologi particulate matter, particularly those applicable to grain receiving systems. Search strategies were developed to retrieve information on relevant echnologies. In scientific databases, the echnolo used were: (dust OR “particulate matter”) AND (control OR treatment). For the national echnol database, the strategies included: “material particulado”, “poeira”, and “despoeiramento”. In the international Espacenet database, the terms were “particulate matter” AND dust AND “atmospheric pollution” AND control, and in the WIPO database: “particulate matter” AND dust AND “atmospheric pollution” The results revealed widely used echnologies, including: conveyor chutes, suction systems, air flow control, filters, sprayers, collectors, cyclones, precipitators, and purifiers. These devices primarily function to reduce particle emissions i into the environment. China currently stands out as a leading holder of echnologies in this sector, showing significant progress in solutions for emission treatment. This leadership reflects continuous investment in research and development, as well as na interest in producing echnologies to meet global demands. In contrast, Brazil also conducts research in this field, but most efforts are driven by academic institutions and technology centers focused on agribusiness. It is concluded that the identified echnologies provide a solid foundation for improvements in particulate matter treatment and support the development of new solutions aimed at improving air quality across various operational settings. After the studies carried out, it was found that the integration of the encapsulation, collection, transport, treatment, and storage modules enables the capture, conveyance, and filtration of the particulate material generated during grain unloading. As a result, these modules reduce atmospheric emissions, improve air quality, and decrease worker exposure to unhealthy conditions.
