Abstract

"DISTRIBUIDOR DE LìQUIDO, COLUNA DE TRANSFERêNCIA DE MASSA, E, MéTODOS PAPA INSTALAR UM DISTRIBUIDOR DE LìQUIDO E PARA DISTRIBUIR LìQUIDO A UM LEITO DE TRANSFERêNCIA DE MASSA". Uma coluna de transferência de massa é fornecida com um distribuidor de líquido que distribui o líquido em um leito de transferência de massa subjacente contendo um ou mais elementos aleatórios, de grade ou de empacotamento estruturado. O distribuidor de líquido inclui uma pluralidade de canaletes alongados que são afastados e que se estendem por toda a coluna. Uma pluralidade de furos de descarga de líquido é posicionada nas paredes laterais do canalete e está localizada em um ou mais planos pré-selecionados que são preferivelmente espaçados acima do fundo do canalete. Os defletores de borrifo são espaçados externamente nas paredes laterais do canalete e incluem porções superiores que são posicionadas para receber o líquido que sai dos canaletes através dos furos de descarga. As porções inferiores dos defletores de borrifo formam uma saída de descarga estreitada em um plano abaixo do canalete para a liberação do líquido dos defletores de borrifo para o leito de transferência de massa subjacente. Os furos de descarga de em uma das paredes laterais do canalete são desviados deste no outra parede lateral do canalete para fornecer uma distribuição uniforme de líquido na saída de descarga. Os defletores de borrifo são verticalmente ajustáveis e são pretendidos para serem suportados na superfície superior do leito de transferência de massa de modo que o líquido descarregado seja liberado diretamente no leito de transferência de massa, reduzindo, desse modo, a oportunidade do líquido que cai vir a entrar em uma corrente de vapor que flui de maneira ascendente através do leito de transferência de massa. O líquido que sai da saída de descarga forma preferivelmente um fluxo semelhante a cortina que bloqueia ou impede que entre de maneira ascendente na saída de descarga. Qualquer vapor que entre na área de descarga é capaz de passar ascendentemente através do espaçamento aberto entre os defletores e os canaletes associados em uma velocidade reduzida, reduzindo, desse modo, a oportunidade da entrada de líquido. O espaçamento aberto também permite que qualquer transbordamento de líquido dos canaletes sejam capturados pelos defletores de borrifo do fluxo descendente ao longo das faces internas dos defletores de borrifo.
