Abstract

sistemas e métodos de limpeza por aplicação de pulso. trata-se de um sistema de filtro que inclui uma folha de tubo que define uma pluralidade de orifícios em comunicação fluida com uma pluralidade de mangas filtrantes. o sistema inclui também uma montagem giratória que tem um braço que define uma ou mais saídas para fornecer ar pressurizado a partir de uma fonte de ar em direção à folha de tubo em resposta à pulsação de um ou mais atuadores. um motor é operacionalmente acoplado à montagem estacionária e à montagem giratória para girar o braço em torno de um eixo geométrico a uma velocidade de rotação predefinida. um controlador é operacionalmente acoplado ao motor e ao um ou mais atuadores para fornecer comandos de pulso com base em um intervalo de pulso e em um intervalo de impulso. o intervalo de pulso e o intervalo de impulso podem ser determinados com base em uma velocidade de rotação medida do braço, que pode ser redeterminada durante a operação.
