Why does tower pressure increase
Thread Content
The company has a low-pressure absorption tower, which has two outlets; one of these outlets leads to the spray tower, where water is used for spraying before the waste gas is discharged； One fan is connected to the air intake, and the outlet of the fan is connected to the combustion furnace. The pressure in the combustion furnace is around 8 kPa; once the fan starts operating, the outlet pressure is approximately 14 kPa. There is a check valve at the fan’s outlet, and the valve is in good condition. If the fan is not turned on now, the tower pressure is at 4 kPa, and it remains stable. If the fan is turned on, the tower pressure gradually increases and can reach 6 KP. At this point, the valve for spraying (venting) remains open; in other words, having the fan running results in a higher tower pressure than when I operate it under normal conditions. (The fan is operating normally, and the pipelines are in good condition as well.)
The fan isn’t installed backwards, is it? Or is the fan rotating in the wrong direction? I’ve encountered a similar situation too – the fan was connected in reverse! ! Hehe
It was supposed to be a suction method, but now it’s become a blowing method
It should be reversed! :lol
The fan circuit is reversed, causing the motor to rotate in the opposite direction
Generally, it’s possible that the fan or its electrical circuit was repaired recently, and the wires were accidentally connected in reverse, causing the motor to rotate in the opposite direction; adjusting the phases will resolve this issue!
The fan must have reversed direction! The fan circuit is wired backwards; try reversing the phases:victory: :victory:
Hehe, it was originally due to negative pressure ventilation; perhaps there was a design mistake that resulted in positive pressure ventilation. There’s nothing to say about it – it just needs to be corrected
Ask whether the electrical equipment and operators have maintained the motor properly; it’s possible that the electrician got the phase sequence wrong, and adjusting it will resolve the issue. The stress tester app for friends can’t be giving false readings, right?
But there is a check valve at the fan outlet. The check valve is in good condition; if it’s connected backwards, then there will be no place for air to enter, right?
