Abstract
Patente de Invenção: <B>"PROCESSO PARA A LIMPEZA DE VELAS DE FILTRO DE UM FILTRO DE VELA"<D>. Processo para a limpeza de velas de filtro de um filtro de vela, com utilização de um líquido de limpeza que corre do lado do produto filtrado para dentro do interior da vela, o qual é prensado de dentro para fora através da vela de filtro, em direção oposta àquela da direção do produto filtrado, mediante um meio gasoso que se encontra sob sobrepressão. Como líquido de limpeza é utilizado de maneira conveniente água, e como meio gasoso ar. Para a distribuição do líquido de limpeza, neste caso são previstos cada vez estreitamentos em forma de bocal colocados na extremidade da vela no lado de descarga, ou à distância deste estreitamento, corpos de choque no interior da vela, com os quais o líquido de limpeza que corre para dentro é desviado para todos os lados em direção às paredes internas da vela. Neste caso pode ser considerado como desvantagem que os estreitamentos em forma de bocal são previstos tanto para a entrada do líquido de limpeza para o interior da vela de filtro como também para o ar comprimido, assim que na ocasião de depositar um impulso de pressão não é possível uma continuação do fluxo de líquido de limpeza. A invenção baseia-se na tarefa de criar uma solução melhorada, com a qual obtém-se, apesar da introdução do meio gasoso que se encontra sob pressão, uma continuação do fluxo do líquido de limpeza como de costume para dentro do interior da vela, assim que pode ser garantida, praticamente de maneira contínua, uma solicitação do espaço interno da vela com este líquido de limpeza. Para isso propõ-se que o líquido de limpeza e o meio gasoso são levados para o interior da vela de filtro por caminhos de corrente separados um do outro.
