Abstract

"SISTEMA PRESSURIZADO DE RELAVAGEM". Trata-se de um sistema de relavagem de filtro, incluindo um acumulador contendo um receptáculo dilatável pressurizado que propele um suprimento de fluido de relavagem, contido no interior do acumulador em uma direção reversa, através de um elemento de filtro. Enquanto que o fluido de relavagem é bombeado no interior do acumulador, um gás inerte no interior do receptáculo dilatável é comprimido de encontro à paredes internas do acumulador. Sob alcance de uma pressão de aproximadamente 300 - 600 psi, o fluido filtrado é liberado a partir do acumulador e a energia total do gás comprimido é liberada da mesma forma. Esta liberação produz um jato rápido, com alta pressão de fluido de relavagem, que efetivamente remove contaminantes que obstrutivos a partir do elemento de filtro.
