<p>PURPOSE:To obtain an air blowing device for an absorption tower without clogging even in long time use by feeding mixed fluid of liquid and the air obtained by an air mixer installed in a discharge line of a reflux pump to a bubble disperser installed in a sump. CONSTITUTION:After liquid in a sump part 5 is sucked by a reflux pump 7 through a reflux line 6 and increased in pressure, it is discharged to a pump discharge line 8. Here an air mixer 9 is provided to make a mixed fluid of liquid from the discharge line 8 and air from an air feed line 10 and the mixture is fed to a bubble disperser 12. Thereby a jetting part of the bubble disperser 12 is washed by the reflux, not causing clogging even the deposit of gypsum proceeds. And since the mixed gas is radially and horizontally jetted from the bubble disperser 12, oxidation is accelerated and agitation effect is increased.</p> |
