Description

Изобретение относитс к адсорбционной очистке и может найти применение в системах осушки и очистки воздуха от влаги и двуокиси углерода, а также в системах получени газов высокой чистоты, в особенности в области криогенного разделени воздуха при глубокой осушке и очистке его от влаги, двуокиси углерода, углеводородов.The invention relates to adsorption cleaning and can be used in drying systems and air purification from moisture and carbon dioxide, as well as in systems for the production of high-purity gases, especially in the field of cryogenic separation of air during deep drying and purification from moisture, carbon dioxide, and hydrocarbons. .
Известен способ безнагревной регенерации адсорбента в установках очистки воздуха типа УОВ и УОВ-Б, заключающийс в том, что часть очищенного в одном из адсорберов воздуха, давление которого составл ет 0,5-1 МПа, пропускают через дроссель , понижа его давление до давлени регенерации 0,01-0,02 МПа, а затем через регенерируемый адсорбер, в котором предварительно снижено давление, вывод т в атмосферу 1.The known method of heatless regeneration of the adsorbent in air purification installations of the type of UOV and WOW-B, is that part of the air purified in one of the adsorbers, whose pressure is 0.5-1 MPa, is passed through the throttle, lowering its pressure to the regeneration pressure 0.01-0.02 MPa, and then through a regenerated adsorber, in which the pressure is preliminarily reduced, are released into the atmosphere 1.
Этот способ св зан с существенными затратами продукционного газа (до 50°/о) и не приводит к глубокой регенерации адсорбента . Точка росы газа, осуш.енного этим способом , обычно не превышает 233К.This method is associated with significant production gas costs (up to 50 ° / o) and does not lead to a deep regeneration of the adsorbent. The dew point of gas dried in this way usually does not exceed 233K.
Известен также способ регенерации адсорбента после завершени цикла адсорбции примесей из газа сжатого до давлени нижеThere is also known a method of adsorbent regeneration after completion of the cycle of adsorption of impurities from compressed gas to a pressure below
критического, включающий снижение давлени Б адсорбере до давлени десорбции путем вывода части газа из адсорбера, последующую десорбцию при давлении ниже критического noTOKOiv нагретого газа и охлаждение адсорбента до температуры адсорбции 2. Охлаждение адсорбента считаетс законченным, когда температура охлаждающего газа, выход щего из адсорбера, а следовательно , и температура адсорбента, выще температуры, при которой происходит изотермическа адсорбци , на 40-50К.critical, which includes reducing the pressure B of the adsorber to a desorption pressure by withdrawing a part of the gas from the adsorber, subsequent desorption at a pressure below the critical heated gas, and cooling the adsorbent to the adsorption temperature 2. therefore, the temperature of the adsorbent, higher than the temperature at which isothermal adsorption takes place, is 40-50K.
Уменьщение указанной разности температуры может происходить за счет увеличени уделЪного расхода охлаждающего таза, который, в р де случаев, вл етс продукционным , снижени его температуры, либоThe decrease in the specified temperature difference may occur due to an increase in the actual flow rate of the cooling pelvis, which, in a number of cases, is production, lowering its temperature, or
5 увеличени продолжительности охлаждени . Ни один из этих методов не может быть реализован в известном способе без ухудшени технических характеристик блока очистки.5 increases the cooling time. None of these methods can be implemented in a known way without degrading the technical characteristics of the cleaning unit.
