PURPOSE:To enhance the collection efficiency of colloidal fine particles, by providing an oxygen injection part, which injects oxygen in condensed water passed through an electromagnetic filter, between the electromagnetic filter and a desalting device while providing a condensed water stirring filter between said oxygen injection part and the desalting device. CONSTITUTION:In condensed water purification equipment equipped with an electromagnetic filter 2 for primarily collecting fine particles in condensed water an a desalting device for secondarily collecting fine particles in condensed water passed through the electromagnetic filter 2, an oxygen injection part 13, which injects oxygen in condensed water passed through the filter 2, is provided between the filter 2 and the desalting device while a condensed water stirring filter 14 is arranged between the oxygen injection part 13 and the desalting device. As a result, the surface charge of colloidal fine particles leaked from the electromagnetic filter is intesified and the collection efficiency of colloidal fine particles by the ion exchange resin allowed to fill the desalting device can be enhanced and, in its turn, the collection efficiency of fine particles as the whole of the equipment can be enhance as compared with conventional one. |
