Abstract
A gas treatment system for treating a gas stream containing contaminants includes first and second gas treatment members in fluid communication with each other. Each of the first and second gas treatment members is selectively controllable between an on and an off condition. A third gas treatment member is in fluid communication with the first and second gas treatment members, and the third gas treatment member selectively retains or releases the contaminants based upon the on or off condition of at least one of the first or second gas treatment members.
Claims15
A gas treatment system for treating a gas stream containing contaminants comprising:
- a first gas treatment member including a photocatalyst and a light source;
- a second gas treatment member including a plasma device, the first and second gas treatment members in fluid communication with each other and each of the first and second gas treatment members is configured to be selectively controllable between an on and an off condition;
- and
- a third gas treatment member including an adsorptive filter and a heater in fluid communication with the first and second gas treatment members, and the third gas treatment member being configured to selectively release contaminants based upon the off condition of the first gas treatment member.

- a first gas treatment member including a photocatalyst and a light source;
- a second gas treatment member including a plasma device;
- and
- a third gas treatment member including an adsorptive filter and a heater, the first, second and third gas treatment members in fluid communication with each other are configured to be selectively controllable between an on and an off condition and are configured to operate between a first mode and a second mode, in the first mode the first gas treatment member is in the on condition and the second and third gas treatment members are in the off condition, and in the second mode the first gas treatment member is in the off condition and the second and third gas treatment members are in the on condition.
