Liquid chlorine vaporizer
Thread Content
Our plant currently uses two sizes of liquid chlorine coil vaporizers—small and large—both of which vaporize chlorine using hot water at 80 degrees. The small vapor vent pipe isn’t frosted; the vent pipe is hot! ! The large vaporizer actually causes frosting on the exhaust pipe, which is slightly cooler! ! In small vaporizers, frost forms when the flow rate is low; conversely, no frost forms when the flow rate is high. In large vaporizers, however, higher flow rates lead to more severe frosting! ! Excuse me? Which type of carburetor is normal? Logically speaking, larger particles should be gasified more completely, right? Why does the exhaust pipe frost over? Which situation is normal? ?
“The same hot water is vaporized at 80 degrees. The small vapor vent pipe isn’t frosted; the vent pipe is hot! ! The large vaporizer actually causes frosting on the exhaust pipe, which is slightly cooler! ! ” Generally, in liquid-liquid chlorine vaporization control, it is the outlet pressure that is regulated. The ratio of the cross-sectional area to the perimeter is the largest among all types of cross-sections. Therefore, given the same valve opening degree, the flow rate through a larger pipe is greater than that through a smaller pipe; consequently, more heat needs to be supplied. If there isn’t enough heat supplied to a larger pipe, frost will form on it.
“In small vaporizers, frost forms when the flow rate is low; conversely, no frost forms when the flow rate is high. In large vaporizers, however, higher flow rates lead to more severe frosting! ! ” Based on your description, there might be a problem with your small carburetor. It’s possible that there’s liquid in the small vaporization tube. This will cause frost to form at a point where the pipe diameter changes after the vaporizer.
In short. Frost forming after the carburetor can be considered an indication that the carburetor is faulty.
