Abstract
célula de ionização negativa de alta eficiência para partículas finas, ultrafinas e nanopartículas, presentes em alta e ultra-alta densidade em fumos, em gases de escape de veículos, e no ar. é descrita uma célula de ionização negativa (1) adequada para ionizar negativamente partículas finas, partículas ultrafinas e nanopartículas presentes em um fluxo de ar definido por fumos, gases de escape de veículos ou no ar de ambientes internos, com o referido fluxo de ar sendo adequado para ser purificado contra tais partículas, onde a dita célula é adequada para prover uma carga elétrica negativa às citadas partículas sólidas (p) contidas em tal fluxo de ar (f) quando ele passa através da célula de ionização (1), com a mencionada célula possuindo um corpo (5) que define uma parte ionizante (2) compreendendo uma primeira (6) e uma segunda (7) porções alongadas, de preferência em forma de placa e voltadas uma para a outra, em que a primeira porção (6) é alimentada com tensão negativa de modo a gerar uma diferença de potencial com a segunda porção (7), com as referidas primeira e segunda porções (6, 7) definindo uma passagem (10) para o fluxo de ar (f); a dita primeira porção (6) suporta uma pluralidade de corpos alongados e pontiagudos (14) que se projetam na passagem (10) para o fluxo de ar (f) e ortogonalmente ao mesmo fluxo de ar, em que os referidos corpos alongados e pontiagudos (14) geram um fluxo de elétrons direcionado para a segunda porção (7), devido à diferença de potencial mencionada, adequado para interceptar as partículas sólidas (p) presentes no fluxo de ar de modo a carregá-las negativamente. além disso, é aqui reivindicado um purificador de ar provido com tal célula de ionização negativa.
