초록 ▼

A pressure swing and temperature swing adsorption system is disclosed which continuously purges contaminants such as nuclear, biological and chemical warfare agents from intake air and provides cool clean air to the crew compartment of a vehicle by progressively directing contaminated air through a first adsorption bed to clean the air, while simultaneously directing hot exhaust gases at about 600°F. through a second adsorption bed for purging contaminants therefrom, while simultaneously cooling a third adsorption bed for enhancing adsorption of contaminants in the purging bed upon repeating the cycles of operation.

대표청구항 ▼

A method for purging contaminants from intake air and providing clean air, comprising the steps of: directing intake air to a first adsorption bed at a first pressure wherein the intake air passes through the first adsorption bed in a first direction producing a clean air output; stopping the flow of intake air to the first adsorption bed; heating the first adsorption bed; passing a portion of the clean air through the first adsorption bed in a second direction, wherein the second direction is opposite to the first direction and wherein the portion of the clean air is at a second pressure which is lower than the first pressure; stopping the heating of the first adsorption bed; cooling the first adsorption bed; cooling the clean air to provide cooled clean air and wherein the step of cooling the first adsorption bed, comprises the step of passing the cooled clean air through the first adsorption bed at a third pressure which is lower than the first pressure; and heating a portion of the intake air, creating heated intake air and wherein the step of heating the first adsorption bed, comprises the steps of providing channels in the first adsorption bed, and passing the heated intake air through the channels in the first adsorption bed. An apparatus for purging contaminants from intake air and providing clean air, comprising: a first adsorption bed; means for directing intake air to the first adsorption bed at a first pressure wherein the intake air passes through the first adsorption bed in a first direction producing a clean air output; means for stopping the flow of intake air to the first adsorption bed and heating the first adsorption bed and passing a portion of the clean air through the first adsorption bed in a second direction, wherein the second direction is opposite to the first direction and wherein the portion of the clean air is at a second pressure which is lower than the first pressure; means for stopping the heating of the first adsorption bed, and cooling the first adsorption bed; means for cooling the clean air to provide cooled clean air and wherein the means for stopping the heating of the first adsorption bed, comprises a means for passing the cooled clean air through the first adsorption bed at a third pressure which is lower than the first pressure; and means for heating a portion of the intake air, creating heated intake air and wherein the means for stopping the flow of intake air to the first adsorption bed and heating the first adsorption bed, comprises channels in the first adsorption bed, and means for passing the heated intake air through the channels in the first adsorption bed.
