Description

Изобретение относитс  к очистке воздуха от углекислого газа на анконообменн сорбентах и может быть использовано дл очистки от СО воздуха в замкнутых помещени х и сжатых баллонных газов. Известные способы очистки воздуха от СОл с использованием анионитов предусматривают сорбцию двуокиси углерода основной или карбонатной формой анионит при атмосферном давлении ij. Наиболее близкий к изобретению способ очистки воздуха замкнутых помещений от углекислоты включает сорбцию последней влажной карбонатной формой анионита и последующую десорбцию углекислоты и регенерацию анионита гор чим вод ным паром с повторным использованием конденсата при многоцикловой работе анионита 2J. Недостатком такого способа  вл етс  низка  скорость поглощени  СО анионитом при атмосферном давлении, в результате чего эффективное использование емкости сорбента возможно только при ско- рост х газового потока меньше О,О5 л/мин-см , Цель изобретени  - увеличение скорости очистки воздуха от двуокиси углерода . Это достигаетс  тем, что в способе очистки воздуха от двуокиси углерода путем адсорбции последней влажной карбонатной формой ашюнита с последующей десорбцией гор чим вод ным паром, сорбцию ведут при давлении 1,5-10 ата. Отклонение в сторону давлений меньше 1,5 ата pGOKO ухудшает кинетические параметры процесса сорбци . Осуществление стадии сорбции при давлени51х воздуха более 10 9та, вызыва  незначительный выигрыш динамической активности сорбента, не окупаетс  технико-энергетическими затратами на сжатие очищаемого воздухао Пример . Газовую смесь с низким содержанием двуокиси углерода (например О,25-1,5 об.% СО-, остальное азот) из баллона с давлегшем до 12О атаThe invention relates to the purification of air from carbon dioxide in anconverter sorbents and can be used to clean the air from CO in closed rooms and compressed balloon gases. Known methods of air purification from SOL using anion exchangers provide for sorption of carbon dioxide by the basic or carbonate form of anion exchanger at atmospheric pressure ij. The closest to the invention method of air purification of closed premises from carbon dioxide includes the sorption of the latter with a wet carbonate anion exchanger and the subsequent desorption of carbon dioxide and the regeneration of the anion exchanger with hot water vapor with repeated use of anion exchanger 2J. The disadvantage of this method is the low rate of CO absorption by the anion exchanger at atmospheric pressure, as a result of which effective use of the sorbent capacity is possible only at gas flow rates less than O, O5 l / min-cm. . This is achieved by the fact that in the method of purifying air from carbon dioxide by adsorbing the latter with a wet carbonate form of ashunite followed by desorption with hot water vapor, sorption is carried out at a pressure of 1.5-10 atm. A deviation in the direction of pressures less than 1.5 atm pGOKO worsens the kinetic parameters of the sorption process. The implementation of the sorption stage at an air pressure of over 10 9 tons, causing a slight gain in the dynamic activity of the sorbent, does not pay for the technical and energy costs of compressing the air being cleaned. Example. Low-carbon dioxide gas mixture (for example, O, 25-1.5 vol.% CO-, the rest is nitrogen) from a cylinder with pressure up to 12O at
