.*·* J 9 Reivindicações; 1.*—Processo para introduzir um gás num filtro de partículas compreendendo elementos filtrantes tubulares (5), em que o gás é feito passar através duma conduta de alimentação (3) fora dos elementos filtrantes (5) do filtro de partículas para um espaço entre os alementos filtrantes, caracterizado pelo facto de o gás a ser purificado ser obrigado a passar para o espaço entre os elementos filtrantes (5) de tal maneira que o caudal de gás da conduta de alimentação (3) em direcção aos elementos filtrantes (5) é substancialmente constante na direcção dos elementos filtrantes (5) ao longo do comprimento dos elementos filtrantes. 2.4—Processo de acordo com a reivindicação 1, caracterizado pelo facto de o gás a ser purificado ser obrigado a passar para o espaço entre os elementos filtrantes (5) através da conduta de alimentação (3) posicionada substancialmente na região central do espaço e a conduta de alimentação (3) ser dotada de aberturas (4) de diâmetro crescente no sentido de passagem do gás para manter substancialmente constante o caudal de gás proveniente da conduta de alimentação (3) ao longo do comprimento da parte da conduta (3) que contém as aberturas (4) . í 3.*—Dispositivo para a realização do processo de acordo com a reivindicação 1, compreendendo uma conduta de alimentação (3) posicionada substancialmente na região central de um espaço entre os elementos filtrantes (5) num filtro de partículas em paralelo com os referidos elementos filtrantes (5), sendo a mencionada conduta de alimentação dotada de, pelo menos, uma abertura de alimentação (4) para introduzir gás fora dos elementos filtrantes (5), caracterizado pelo facto de a referida conduta de alimentação (3) ser fechada no topo, a mencionada conduta de alimentação (3) ser dotada com diversas aberturas de alimentação (4) substancialmente dispostas simetricamente em volta do seu eixo longitudinal e ao longo do comprimento dos elementos filtrantes (5) para darem passagem ao gás para fora da conduta de alimentação (3) na sua direcção transversal e os diâmetros das aberturas (4) aumentarem no sentido de passagem do gás para manter substancialmente constante o caudal de gás dirigido para os elementos filtrantes (5) ao longo do comprimento dos elementos filtrantes (5) . 4. * — Dispositivo de acordo com a reivindicação 3, caracterizada pelo facto de a conduta de alimentação (3) compreender fiadas de aberturas (4) nela formadas posicionadas axialmente em sucessão de maneira substancialmente simétrica em relação à periferia da conduta de alimentação (3).Claims; 1. A process for introducing a gas into a particulate filter comprising tubular filter elements (5), wherein the gas is passed through a feed duct (3) out of the filter elements (5) of the particulate filter into a space characterized in that the gas to be purified is forced to pass into the space between the filter elements (5) in such a way that the gas flow of the feed duct (3) towards the filter elements ) is substantially constant towards the filter elements (5) along the length of the filter elements. Process according to claim 1, characterized in that the gas to be purified is required to pass into the space between the filter elements (5) through the feed duct (3) positioned substantially in the central region of the space and (3) is provided with apertures (4) of increasing diameter in the gas passage direction to maintain substantially constant the gas flow from the feed conduit (3) along the length of the portion of the conduit (3) which contains the openings (4). 3. A device for carrying out the method according to claim 1, comprising a feed duct (3) positioned substantially in the central region of a space between the filter elements (5) in a particulate filter in parallel with said filters (5), said supply line being provided with at least one feed port (4) for introducing gas out of the filter elements (5), characterized in that said feed line (3) is closed at the top, said feed line (3) is provided with a plurality of feed apertures (4) substantially symmetrically disposed about their longitudinal axis and along the length of the filter elements (5) to pass the gas out of the conduit (3) in its transverse direction and the diameters of the openings (4) increase in the direction of passage of the gas to maintain substantially constant (5) along the length of the filter elements (5). 4. Device according to claim 3, characterized in that the feed duct (3) comprises rows of apertures (4) formed therein positioned axially successively substantially symmetrically with respect to the periphery of the feed duct (3) ). 11 5.a — Dispositivo de acordo com a reivindicação 3, caracterizado pelo facto de a conduta de alimentação compreender diversas aberturas (14) substancialmente contínuas ao longo do comprimento dos elementos filtrantes (5) e de largura crescente no sentido da passagem do gás.
