Abstract
An apparatus for removing gaseous contaminants from an air flow which divides the air flow into a first air flow and at least one other air flow. A cleaning device cleans the first air flow and the cleaned airflow combines with all other air flows to form an outlet air flow. The first air flow is small when compared to the sum of the first air flow and each other air flow. The gas phase cleaning device passes the entire first air flow through a cleaning bed having a thickness of greater than the Critical Thickness for the contaminant of concern.
Claims24
An apparatus for removing gaseous contaminants from an air flow including:
- a means to divide the air flow into a first air flow and at least one other air flow such that the first air flow is small when compared to the sum of the first air flow and each other air flow;
- a gas phase cleaning device for cleaning the first air flow;
- and
- a means to combine the cleaned first air flow and all other air flows to form an outlet air flow;
- where the gas phase cleaning device passes the entire first air flow through a cleaning bed having a thickness of greater than the Critical Thickness for the contaminant of concern.
An apparatus according to any one of the previous claims wherein the gas cleaning device includes a fan.
An apparatus according to any one of the previous claims wherein the gas phase cleaning device includes at least one particulate arresting filter.
An apparatus according to any one of the previous claims wherein the intake air flow is divided into a first air flow and a second air flow.
An apparatus according to any one of the previous claims wherein the constant proportion of contaminant removed from the first air flow is at least 98%.
A method for removing gaseous contaminants from an air flow including the following steps:
- dividing the air flow into a first air flow and at least one other air flow;
- cleaning the first air flow by passing the entire first air flow through a gas phase cleaning device that includes a cleaning bed having a thickness of greater than the Critical Thickness for the contaminant of concern.;
- and
- combining the cleaned first air flow and all other air flows to form an outlet air flow;
- where the first air flow is small when compared to the sum of the first air flow and each other air flow.
