<p>PURPOSE:To prevent cavitation by introducing a part of the circulating soln. contg. an absorbent into an air suction-type ejector to separate steam by gas-liq. contact, and then injecting the liq. layer part into the lower liq. chamber of an absorption tower. CONSTITUTION:Exhaust gas 1 is sent into the absorption tower 6 through a cooling tower 4, gas-liq. contact is carried out in the packed bed 7 wetted with the circulating soln. sprayed from a spray nozzle 8, and SOX is absorbed. The circulating soln. is transiently accumulated in the liq. chamber 10 at the lower part of the absorption tower 6, and then circulated to spray nozzles 5 and 8 through a circulating pump 12. A part of the circulating soln. is introduced into an ejector 20 through a line 21, brought into contact with air to oxidize the sulfite ion, then introduced into a steam separator 23 to separate steam, and finally injected into the liq. chamber 10 through a line 24 to agitate the inside of the liq. chamber.</p> |
