Abstract:
PROBLEM TO BE SOLVED: To improve electrostatic collection performance by preventing electrostatically collected fine particles from scattering again by impact in collection, or separating to be discharged, in an exhaust gas treatment apparatus of an internal combustion engine using corona discharge. SOLUTION: A corona discharge electrode 2 and an electrostatic collection metal filter 3 being a dust collection electrode are oppositely arranged nearly at the center part of an exhaust passage 11 of an internal combustion engine and its downstream side, respectively. The electrostatic collection metal filter 3 comprises: an inner peripheral passage 32 having a hollow tubular shape and continuing to the exhaust passage 11; and a conductive outer peripheral filter part 31 formed with a cylindrical wall part in its circumference, attracts aggregated fine particles included in an exhaust gas flow to the outer peripheral filter part 31 by Coulomb's force, and inductively retains them in multiple partitioned capture space parts 33 opened to the inner peripheral passage 32.

PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of easily recovering insulating performance, without damaging an insulator. SOLUTION: This exhaust emission control device has a discharge electrode 12 having a discharge part 12d arranged inside an exhaust passage for passing exhaust gas, generating corona discharge by impressing high voltage from a high voltage power source part 15 between the part and an inner wall of the exhaust passage and electrifying and flocculating an exhaust particulate in the exhaust gas by the corona discharge and an insulator part 12b for surrounding and insulating the outer periphery of a conductive part except for the discharge part; and comprises a power supply control part 16 for controlling an impression state of the high voltage on the discharge electrode 12 from the high voltage power source part 15 so as to recover reduction in the insulating performance by sticking of an exhaust gas component to the insulator part 12b.

Abstract:
Embodiments of the invention involve the application of a disk-in-tube type of "wet" or "dry" ESP (electrostatic precipitation) technology for the capture/removal of airborne particles entering a gas turbine compressor. This provides an effective method of particulate removal without the inefficiencies associated with conventional filtering techniques. Embodiments of the innovative approach also eliminate the inlet airstream blocking effect of a conventional filter, thus making its use and operation adaptable to different operating environments and processes that require clean input air streams (including industrial manufacturing processes, power generators, combined turbine and fluid recapture systems for use in heating and cooling, etc.).

Abstract:
A hand dryer assembly including a blower assembly for generating a moving air stream. The moving air stream passes through an air channel to an air outlet where it exits the hand dryer assembly. An ionization assembly is disposed along the air channel and emits charged ions directly into the moving air stream, sanitizing the hands of the user, the moving air steam, and the ambient air that is entrained into the moving air stream.
