Abstract

Patente de Invenção: <B>"PROCESSO PARA A LIMPEZA DE UMA CAIXA DE FILTRO"<D>. A invenção refere-se a um processo para a limpeza de caixas de filtro, especialmente para a limpeza do espaço do produto não filtrado de filtros de caldeiras, sendo que velas de filtração são suportadas em um fundo intermediário que separa o espaço do produto filtrado do espaço do produto não filtrado e que o espaço do produto não filtrado pode ser solicitado com um líquido de limpeza, assim como a um dispositivo para a limpeza de tais caixas de filtro. Com a invenção deve ser possível solicitar as paredes internas de um filtro desse tipo com líquido de limpeza partindo já da região superior abrangendo-as em essências totalmente. Para este fim, a invenção prevê que na região superior do espaço do produto não filtrado é dirigido um meio de limpeza contra a parede inferior do fundo intermediário e/ou contra a região superior da parede do espaço do produto não filtrado com tal direção de corrente que um filme de limpeza em essência fechado é conduzido partindo da parede superior do espaço do produto não filtrado ao longo dessa para baixo.
