Abstract

Изобретение относитс  к технологии очистки газов от аэрозолей NH4C1 и НС1, примен емой в производстве графитированных тканевых материалов и позвол ющей повысить степень очистки. Отход щие газы, содержащие аэрозоли NH4C1 и СН1, промывают водным раствором, содержащим 10,0- 27,0 мас.% NH4C1. рН раствора поддерживают в интервале 3,0-5,0 добавлением в раствор аммиака. Степень очистки от аэрозолей 99,9%. 1 табл.The invention relates to the technology of purification of gases from NH4C1 and HC1 aerosols, used in the manufacture of graphitized fabric materials and allowing an increase in the degree of purification. The waste gases containing aerosols NH4C1 and CH1 are washed with an aqueous solution containing 10.0-2.7.0 wt.% NH4C1. The pH of the solution is maintained in the range of 3.0-5.0 by adding ammonia to the solution. The degree of purification from aerosols 99.9%. 1 tab.

Изобретение относитс  к очистке газов от аэрозолей сол ной кислоты и хлорида аммони , разработано применительно к очистке газов производства графитированных тканевых материалов и может быть использовано в химической, металлургической и других отрасл х народного хоз йства, содержащих в выбросах аналогичные примеси.The invention relates to the purification of gases from aerosols of hydrochloric acid and ammonium chloride, developed in relation to the purification of gases produced by graphitized fabric materials and can be used in the chemical, metallurgical and other national households containing similar impurities in their emissions.

Цель изобретени  - упрощение процесса при обеспечений высокой степени очистки.The purpose of the invention is to simplify the process while ensuring a high degree of purification.

Пример. Отход щие газы про- изводства графитированных тканевых материалов, содержащие аэрозолиExample. Exhaust gases from the production of graphitized fabric materials containing aerosols

сол ной кислоты и хлорида аммони , подают на промывку растворами хлорида аммони  концентрации 10,0-27,0 мас.% при рН от 1,0 до 8,0, поддерживаемом автоматически добавлением к промывному , раствору аммиака.hydrochloric acid and ammonium chloride, are fed to the washing with ammonium chloride solutions with a concentration of 10.0-27.0 wt.% at a pH of 1.0 to 8.0, supported automatically by addition to the washing solution of ammonia.

Результаты по степени извлечени  аэрозолей N и НС1 приведены в таблице.The results for the degree of extraction of the N and HC1 aerosols are given in the table.

Услови  эксперимента: концентраци  аэрозолей 0,28 г/м , НС1 0,62 г/м , температура очищаемого газа 20-30 С.Experimental conditions: aerosol concentration 0.28 g / m, HC1 0.62 g / m, temperature of gas to be purified 20-30 C.

Как следует из таблицы, предлагаемый способ обеспечивает степень очистки до 99,9% по обеим примес м и упрощение процесса за счет двух- стадийной обработки газов.As follows from the table, the proposed method provides a degree of purification of up to 99.9% for both impurities and simplifies the process due to two-stage treatment of gases.
