Can the vacuum pump outlet pipeline be connected directly to the spray tower inlet pipeline?
Thread Content
There is a small amount of acidic non-condensable gas at the outlet of the water ring vacuum pump, which needs to be sent to the spray tower (with the induced draft fan located downstream of the spray tower) for treatment. Can the outlet of this pump be directly connected to the inlet pipeline of the spray tower via pipes? If so, what are the special requirements for the equipment?
It mainly depends on the pressure at the inlet of the spray tower; generally, the pressure at the outlet of the vacuum pump is very low, and this is sufficient if the spray tower operates at atmospheric pressure.
There is an induced draft fan downstream of the spray tower, so the inside of the tower is under negative pressure.
It depends on your process design, but generally speaking, it should be unfeasible, as water ring vacuum pumps discharge a mixture of vapor and water... If such a design is desired, comprehensive consideration is needed!
Based on the operating conditions of your spray tower, it should not affect the operation of the vacuum pump; it’s completely fine.
