Title: Method for reducing entrainment of mercury from circulating liquid cooling tower for dehumidifying waste gas
Inventor: FUKIHARU MINEO
IPC: B01D53/64
Filed: 1985-09-04
Abstract: PURPOSE:To reduce the entrainment of mercury from a cooling tower by treating colloidal mercury or a water-insoluble mercury compd. in a circulating liq. for dehumidifying washed combustion waste gas with air or an oxidizing agent in a circulating liq. vessel. CONSTITUTION:The substances contained in the combustion waste gas G1 are absorbed and removed in a cooling and absorption part 2 and then the gas is brought into contact with a circulating liq.8 cooled in a direct cooling tower 6 and dehumidified and discharged to the outside from the top of the tower through a mist separator. Air is blown into the circulating liq. which flows down after contact with the waste gas in a circulating liq. receiving tank 11, and the mercury dispersed in the colloidal form is entrained by the exhaust gas and removed. Or the mercury is converted into a water-soluble substance and the amt. of dispersed colloidal mercury which is easily splashed and transferred into the air when brought into contact with air in the cooling tower 6 is reduced. Besides, the gas can be easily made harmless in the treatment with the blown-in air, by cooling, condensation, etc., since the amt. of air discharged is smaller than the amt. of air discharged from the cooling tower and the mercury concn. is high.
