Abstract

APARELHO DE EVAPORAÇçO INDUSTRIAL. É objeto da invenção, no caso de aparelho em que um material contendo líquido, de ponto de ebulição menor do que o do líquido, é levado a fluir descendentemente ao longo de uma superficie externa de uma guia, durante este tempo o material de ponto de ebulição menor é evaporado, para prover um aparelho especifico que pode ser operado estavelmente durante um período de tempo prolongado em escala industrial de modo que não menos que 1 tlhora do líquido é submetida à evaporação e, além disso, prover um aparelho de evaporação industrial específico em que não ocorrem problemas devido à degeneração causada por residência de alguma parte do líquido no aparelho durante período de tempo longo. Os presentes inventores concluíram a invenção quando descobriram que o objeto acima podia ser alcançado, e que um líquido concentrado ou polímero de condensação ou termoplástico, de qualidade e pureza elevadas, poderia ser facilmente obtido, usando um aparelho de evaporação industrial com uma estrutura especificada em que são dispostas guias que não tem, elas mesmas, uma fonte de calor, um membro de controle de trajeto de fluxo, tendo a função de levar o líquido alimentado sobre a placa perfurada de uma abertura de recepção de líquido, a fluir prmcipalmente a partir de uma porção periférica em direção a uma porção do meio a placa perfurada é provido em uma zona de alimentação de liquido, a relação do volume V (mü) do espaço em que o líquido pode estar presente na zona de alimentação de líquido do fundo da abertura de recepção de líquido (isto é, a junção entre a abertura de recepção de líquido e uma parede interna de topo da zona de alimentação de liquido) para uma superficie superior da placa perfurada, e a área de superfície superior T (m²) da placa perfurada, incluindo a área de superfície superior dos furos na mesma, isto é, o valor de V/T, está em uma faixa especificada na (fórmula (6)) e fórmulas (1) a (5), ou fórmulas (1) a (12), ou fórmulas (1) a (14), são atendidas.
