Description
Известны лабораторные способы определени коэффициентов массопередачи, необходимые дл расчета абсорберов, в которых улавливаютс пары спирта на спиртовых заводах. К ним относ тс методы , основанные на насыщении воздуха парами „ спирта, кип чением спирта, бар-ботажем воздуха через слой спирта, продува-нием воздуха через насаэдку, орошаемую спиртгам.Laboratory methods are known for determining mass transfer coefficients necessary for calculating absorbers in which alcohol vapors are captured in alcohol factories. These include methods based on saturating the air with alcohol vapors, boiling alcohol, bar-booting air through a layer of alcohol, blowing air through an ice-drip spray irrigated with alcohol.
Предлагаетс способ дл определени коэффициентов массопередачи при абсорбции паров этил-ового спирта вадой. Способ заключаетс в том, что воздух предварительно насыщаетс парами спирта, распыленного при помощи форсуно,к в смесителе-испарителе. Дл устранени уноса капель спирта при большой скорости воздуха насыщенный воздух после смесител -испарител проходит брызгоуловитель и далее поступает на абсорбцию в тарельчатую или насадочную колонку из оргстекла, где пары спирта поглощаютс водой. Дл определени .коэффициентов массопередачи замер етс содержание спирта в воздухе до колонки при помощи газометра и бар.ботера, заполненного смесью хромпика и серной кислоты. Содержание спирта в воздухе после колонки определ етс газометром и барботером. Коэффициенты массопередач можно определ ть и по содержанию спирта в воде.A method is proposed for determining the mass transfer coefficients of ethyl alcohol vapor absorption by vadou. The method consists in that the air is pre-saturated with vapors of alcohol sprayed with a nozzle, to the mixer-evaporator. To eliminate the entrainment of alcohol droplets at high air speeds, saturated air after the mixer-evaporator passes a drip pan and then enters the absorption into a pan or packed column from plexiglass, where alcohol vapors are absorbed by water. To determine the mass transfer coefficients, the alcohol content in the air is measured up to the column using a gas meter and a baroteter filled with a mixture of chromium and sulfuric acid. The alcohol content in the air after the column is determined by a gas meter and a bubbler. Mass transfer coefficients can also be determined from the alcohol content in water.
Отличительной особенностью предлагаемого способа вл етс насыщение .воздуха парами спирта в смесителе-испарителе, в котором дозированное количество спирта распыл етс форсунками.A distinctive feature of the proposed method is the saturation of air with alcohol vapors in a mixer-evaporator, in which a metered amount of alcohol is sprayed by nozzles.
Предлагаемый способ насыщени воздуха распылением спирта форсунками более прост по технологическому оформлению, позвол ет в шароких пределах измен ть параметры проведени эксперимента и сокращает расход и потерю спирта на один опыт по сравнению с известными способами.The proposed method of saturating air by spraying alcohol with nozzles is simpler in terms of technological design, allows varying the experimental parameters within a narrow range, and reduces the consumption and loss of alcohol by one experiment compared to known methods.
