Description

(54) ВСПОМОГАТЕЛЬНЫЙ ФИЛЬТРУЮЩИЙ МАТЕРИАЛ(54) AUXILIARY FILTER MATERIAL

1one

Изобретение относ тс  к производству пигментной двуокиси титана, получаемой по сернокислому способу и может быть использовано в других отрасл х народного хоз йства, в том числе в гидрометаллургических процессах, где необходимо раздел ть тонкодисперсные суспензии с применением вспомогательных фильтрующих веществ.The invention relates to the production of titanium dioxide pigment produced by the sulphate method and can be used in other branches of the national economy, including in hydrometallurgical processes, where it is necessary to separate finely dispersed suspensions using auxiliary filtering substances.

Известно, что дл  некоторых тонкоднсперсных плохо фильтруемых суспензий примен ют фильтрацию через намывной слой вспомогательных веществ на фильт рах различной конструкции. В производств пе пигментной двуокиси титана примен ют намывной слой из древесной муки p-J.It is known that for some thinly poorly filterable suspensions, filtration through a precoat of auxiliary substances is used on filters of various designs. In the production of titanium dioxide pigment dioxide, a p-J wood flour is used for the alluvial deposit.

Однако древесна  мука  вл етс  дорогим и остро дефицитным материалом.However, wood flour is an expensive and acutely scarce material.

: Дл  устранеш1Я указанного недостатка три фильтрации тонкодисперсных и трудно фильтруемых суспензий (лейкоксениаированных ильменитовых концентратов) используют промышленные отходы производства , загр зн ющие сточные воды, - гидролизный лигнин.: To eliminate this drawback, the three filtration of finely dispersed and difficult to filter suspensions (leucoxenated ilmenite concentrates) use industrial production wastes that pollute wastewater - hydrolysis lignin.
