GASEOUS NH3 DILUTION TANK

PROBLEM TO BE SOLVED: To enhance dissolving capacity of gaseous NH3 in water when gaseous NH3 is jetted from a jetting nozzle at the tip of a gaseous NH3 flowing pipe immersed in diluting liquid and a part thereof is dissolved in the dilution liquid by providing a bubble breaking means for dividing bubbles of the jetted gaseous NH3 . SOLUTION: Gaseous NH3 11 sent from a liquefied NH3 tank, a NH3 vaporizer, an accumulator and the like in NH3 facilities passes through a gaseous NH3 pipe 13 installed in a dilution tank 1 and is jetted into water in the dilution tank 1 through a jetting nozzle provided on a header 15 at the tip thereof. The jetted gaseous NH3 is turned into bubbles, which rise in the water in the dilution tank 1. In a process in which the bubbles rise, since a bubble breaking device 35 installed on the way is constituted of Raschig rings or wire meshes, when bubbles pass through the bubble breaking device 35, the bubbles are divided into small bubbles and diffused, which increases the contact area between the gaseous NH3 and the water and dissolving capacity of the gaseous NH3 in water is increased.
