Abstract
Изобретение относитс к очистке и позвол ет повысить фильтрующую способность сетчатого фильтра. Сетчатый фильтр обрабатывают органическим растворителем-диметилформамидом при температуре его кипени . Затем фильтр подвергают обработке 20-30%-ным водным раствором кали с последующим пропусканием острого пара через раствор. 1 табл.The invention relates to the purification and allows to increase the filtering ability of the screen filter. The screen filter is treated with organic solvent dimethylformamide at its boiling point. Then the filter is treated with a 20-30% aqueous solution of potassium, followed by passing steam through the solution. 1 tab.
Description
Изобретение относитс к способу очистки сетчатого фильтра преимущественно при производстве присадок.This invention relates to a method for cleaning a screen filter primarily in the manufacture of additives.
Целью изобретени вл етс повышение восстановлени фильтрующей способности фильтра.The aim of the invention is to increase the recovery of the filtering ability of the filter.
Примеры 1и2. Образец фильтровальной сетки, используемый в фильтровальном оборудовании при производстве присадки Днепрол размером 160 мм3, обрабатывают органическим растворителем - диметилформ- амидом, при температуре его кипени (t ) в течение 30 мин. Растворитель сливают, образец промывают водой и помещают в 20-30%-ный водный раствор калиевой щелочи, куда подают острый пар (t°0pct 130°С) в течение часа. Раствор щелочи сливают, сетку промывают водой до нейтральной реакции и затем сушат.Examples 1 and 2. A sample of the filtering mesh used in filtration equipment in the manufacture of the Dneproles size 160 mm3 is treated with an organic solvent, dimethylformamide, at its boiling temperature (t) for 30 minutes. The solvent is drained, the sample is washed with water and placed in a 20-30% aqueous solution of potassium alkali, where the steam is supplied (t ° 0pct 130 ° C) for one hour. The alkali solution is drained, the mesh is washed with water until neutral, and then dried.
Результаты степени очистки приведены в таблице.The results of the degree of purification are shown in the table.
Ведение процесса предлагаемым способом позвол ет повысить восстановление фильтрующей способности фильтра за счет полной его очистки, а такжеConducting the process by the proposed method allows to increase the recovery of the filtering ability of the filter due to its complete cleaning, as well as
