Description
Изобретение относитс к очистке воды и может быть использовано в теплоэнергетике при очистке парового конденсата от железа, в фармацевтической промышленности, а также других отрасл х, где используют воду глубокой степени очистки.The invention relates to the purification of water and can be used in heat and power engineering during the purification of steam condensate from iron, in the pharmaceutical industry, as well as in other branches where water of a high degree of purification is used.
Целью изобретени вл етс повышение степени очистки.The aim of the invention is to increase the degree of purification.
Очистку осуществл ют путем фильтрации воды через слой полимерного материала, в качестве которого используют продукт поликонденсации ал- килфенола с уротропином - алкилфенол- аминную смолу октофор N.The purification is carried out by filtering water through a layer of polymeric material, in which quality the product of the polycondensation of alkylphenol with hexamine, an alkylphenol-amine resin, octofor N, is used.
Октофор N используют в качестве добавки в производстве резинотехнических изделий и в текстильнойOktofor N is used as an additive in the manufacture of rubber products and in textile
промышленности. Смола имеет молекул рную массу 900-1100 и температуру плавлени 95-105 С. Присутствие в молекуле смолы гидроксильных групп и аминного азота в количестве 2,5- 3,5% обеспечивает удаление железа одновременно как по механизму ионного обмена, так и комштексообразо- вани .industry. The resin has a molecular weight of 900-1100 and a melting point of 95-105 C. The presence of hydroxyl groups and amine nitrogen in the resin molecule in an amount of 2.5-3.5% ensures the removal of iron at the same time both by the ion exchange mechanism and by combining .
Способ осуществл ют следующим образом.The method is carried out as follows.
В стекл нную колонку размером 10 X 100 мм помещают 6 г порошка ок- тофора N фракции 20-90 мкм и пропускают паровой конденсат при с объемной скоростью 2-8 л/ч. Содержание железа в фильтрате определ ют по реакции с сульфосалициловой киссо6 g of an oktophoric powder of fraction N 20–90 µm are placed in a 10 × 100 mm glass column and the steam condensate is passed at a bulk flow rate of 2–8 l / h. The iron content in the filtrate is determined by reaction with sulfosalicylic acid.

Regeneration of the resin was carried out with a 2X hydrochloric acid solution, followed by washing with water. A precious resin can be used multiple times. A change in the pH of the condensate within 3-7 does not affect the efficiency of the purification process.
Пример. Очистке подвергают конденсат с содержанием железа 580 мкг/л. Конденсат при пропускают через колонку с октофором N с объемной скоростью 6 л/ч. Количество пропущенного конденсата на 1 кг смолы 275 л. Содержание железа в фильтрате - 24 мкг/л. Степень очистки 96ZtExample. Cleaning is subjected to condensate with an iron content of 580 μg / L. The condensate is passed through a column with octoform N with a bulk velocity of 6 l / h. The amount of leaked condensate per 1 kg of resin is 275 liters. The iron content in the filtrate is 24 µg / l. Degree of cleaning 96Zt
