| 摘要 |
The invention relates to a method for collecting fine particles from flue gases onto selected collector surfaces, in which method flue gases (PK) containing fine particles (H) exiting the combustion chamber are led to a selected chamber (20) delimited by walls (200), which is part of the flow channel of the flue gas, with the aid of a corona discharge of a high-voltage corona electrode (303) of an ion source (100), gas ions (IK) are created in a separate body (110), the gas ions (IK) formed are led to the chamber (20) and mixed with the flue gases (PK), in order to charge- the fine particles (H) with the- aid of the gasions (IK), and the charged fine particles (VH) are collected on the collector surfaces (KP), the said separate body (110) is an electrically passive part of- the ion source (100), a counter potential to the corona electrode (303) is formed as is a collector surface (KP) for the charged particles (VH) from the walls (200), of the said selected chamber (20). The invention also relates to. a corresponding device and arrangement for collecting fine particles from flue gas. |
