PURPOSE:To suppress the blocking of a condensed water outlet pipe by phosphoric acid adhesion, and prevent the counterflow of condensed water by setting a condensed water basin in a condensed water depositing part in a waste gas condensed water recovering device, and applying a water seal structure to the condensed water outlet pipe. CONSTITUTION:A condensed water basin 5 is set in a condensed water depositing part in a waste gas condensed water recovering device, and the water basin 5 is partitioned by a weir 6 and divided into a phosphoric acid precipitating part 8 and a condensed water supernatant recovering part 9. A condensed water drop guard 7 extended down is provided in a position lower than the upper end of the weir 6 so as to cover the upper part of the part 9. A water seal is thus formed by the weir 6, the drop guard 7, and the filled water, and a water seal structure is applied to a condensed water outlet pipe 4 or the lead part of the pipe 4. Thus, the drop guard 7 prevents the condensed water containing phosphoric acid from a water gas cooling water pipe bundle 2 from being directly dropped to the part 9. Thus, the blocking of the pipe 4 by phosphoric acid adhesion can be suppressed, and the counterflow of the condensed water in the system can be also prevented even when the pipe 4 is blocked. |
