Abstract
Provided herein are methods of capturing particulates. The methods may include contacting particulates in a gas stream with one or more acoustic waves. The one or more acoustic waves may include standing waves or waves of modulating frequency. The methods may include promoting agglomeration of particulates with an electrostatic force. Also provided herein are systems for capturing particulates.
Claims30
A method of capturing particulates, the method comprising:
- providing a gas stream in a channel having a longitudinal axis, the gas stream having a velocity and comprising particulates;
- and
- contacting the particulates with one or more acoustic waves having an intensity and a modulating frequency to transport at least a portion of the particulates transversely to the longitudinal axis to a quiescent zone of the channel.
A method of capturing particulates, the method comprising:
- providing a gas stream in a channel having a longitudinal axis, the gas stream comprising particulates;
- contacting the particulates with one or more standing acoustic waves extending transverse to the longitudinal axis to immobilize at least a portion of the particulates;
- and
- contacting the at least a portion of the particulates with an electrostatic force to (i) transport the at least a portion of the particulates to a quiescent zone of the channel, (ii) promote agglomeration of the at least a portion of the particulates, or (iii) a combination thereof.
1 more element
A system for capturing particulates, the system comprising:
- a chemical apparatus;
- a gas stream channel having a longitudinal axis associated with the chemical apparatus;
- and
- two or more transducers associated with the gas stream channel;
- wherein the two or more transducers are configured to provide one or more acoustic waves in the gas stream channel, transversely to the longitudinal axis.
