Description
Известно применение хлора дл регенерации активированного угл , примен емого в процессе очистки сточных вод от тетраэтилсвинца.The use of chlorine for the regeneration of activated carbon used in the process of purifying wastewater from tetraethyl lead is known.
Описываемый способ регенерации активированного угл с применением хлора предусматриваетс дл углей, насыщенных парами тр траэтилсвинца в процессе очистки воздуха и других газов. Способ позвол ет восстановить активность угл и извлечь из него свинец.The described method of activated carbon regeneration using chlorine is provided for coals saturated with tra-ethyl lead vapor in the process of air purification and other gases. The method allows the recovery of the activity of the coal and the extraction of lead from it.
Оссбекнссть способа заключаетс в том, что регенерацию производ т смесью хлора с воздухом в отношении 1 ; 500 с последующей отмывкой образовавнгегос хлористого свинца гор чей водой.The process is based on the fact that the regeneration is carried out with a mixture of chlorine and air with respect to 1; 500 followed by washing of lead chloride with hot water.
Способ осуществл ют следующим образом.The method is carried out as follows.
Отработанный, насыщенный парами тетраэтилсвинца, сорбент непосредственно в адсорбере обрабатывают газообразным хлором в смеси с воздухом в объемном отношении, примерно 1 : 500. Газовоздущна смесь нросасываетс через слой отработанного сорбента, нри этом свинцовые и свинцово-органические соединени , взаимодейству с хлором, переход т в хлористый свинец. Расход хлора в пересчете на тетраэтилсвинец , составл ет 0,7-0,75 кг на 1 кг тетраэтилсвинца.Spent tetraethyl lead saturated with vapor, directly in the adsorber, the sorbent is treated with chlorine gas mixed with air in a volume ratio of about 1: 500. The gas-air mixture is absorbed through the layer of the spent sorbent, while this lead and lead-organic compounds interact with chlorine and transfer into lead chloride. Chlorine consumption, in terms of lead tetraethyl, is 0.7-0.75 kg per kg of lead tetraethyl.
Добавление воздуха к газообразному хлору способствует равномерному раснределению хлора в слое угл и позвол ет избежать местных его перегревов.Adding air to the chlorine gas contributes to the uniform distribution of chlorine in the coal layer and avoids its local overheating.
Хлористый свинец вымывают из сорбента гор чей водой нри 80- 95. Расход воды на 1 кг сорбента составл ет 50-55 л. Степень вымывани хлористого свинца из сорбента-85-90%,Lead chloride is washed out of the sorbent with hot water at 80–95. Water consumption per 1 kg of sorbent is 50–55 l. The degree of leaching of lead chloride from the sorbent is 85-90%,
Из промывных вод свинец может быть прибавлением к ним сульфатов (сернокислого натри или магни ) или сернистых соединений .From wash water, lead can be the addition of sulphates (sodium or magnesium sulphate) or sulfur compounds to them.
После просушки регенерированный сорбент используетс по назначению .After drying, the regenerated sorbent is used for its intended purpose.

Предмет изобретени Subject invention
Способ регенерации активированного угл , -насыщенного тетраэтилсвинцом , при помощи хлора, о-тл ич ающи и с тем, что, с целью восстановлени активности угл и извлечени свинца, регенерацию производ т смесью хлора с воздухом в отнощении 1 :500 с последующей отмывкой образовавшегос хлористого свинца гор чей водой.The method of regenerating activated carbon, saturated with tetraethyl lead, with the aid of chlorine, is otlichayuschie and so that, in order to restore the activity of the coal and remove lead, the regeneration is performed with a mixture of chlorine and air in relation to 1: 500 with subsequent washing of the resulting chloride lead hot water.
