Abstract
The article is devoted to flue gas cleaning, using fly ash as an example. Electrocyclone can be employed as gas-cleaning equipment. The electrocyclone operation can be intensified by reducing re-entrainment. The laboratory model of the annular channel of the electrocyclone is used to show the possibility of reducing re-entrainment by using the shaped elements of various designs on the collecting electrodes. Aerosol industrial emissions can be reduced by using an electrocyclone with modified collecting electrodes.
Highlights
Technological advancement implies a continuous increase in the capacities of industrial companies
A comprehensive study of this type of gas cleaning devices could lead to the introduction into the industry of a new type of highly efficient gas cleaning devices
A larger concentration of ions and larger electric field strength contribute to increasing the maximum possible charge as well as more intense particle charging. This increases the rate of the large particles migration to the collecting electrode by a few to a few dozen times
Summary
Technological advancement implies a continuous increase in the capacities of industrial companies. The effectiveness of the profiled elements of different shapes is considered. For visual observation and quantification of the effectiveness of the profiled elements, a stand was assembled. Re-entrainment is associated with ejection of the entrapped materials on the collecting electrodes.
