I need help understanding the purpose of such a design
Thread Content
I would like to ask the experts: In the diagram, it shows the pipeline through which condensate flows into the storage tank. Why is there a pipeline in the shape of a \" several \" in the area marked in red? What is its purpose?
Is there a missing valve on the bypass pipeline? Otherwise, it seems to have no effect.
Bro, send over the whole drawing
It seems to be the effect of the first condensation seal
Bro, could you tell me what the nitrogen pressure is before and after the stand-alone pressure regulator on the nitrogen pipeline of your system? The answer to the question regarding this post is: A U-tube device utilizes a U-shaped tube filled with liquid; it relies on the height of the liquid level in the U-tube to prevent the discharge of materials from the system, thereby preventing the escape of gases and maintaining a certain pressure within the system. Source: HG/T20570.17-95
The first condensation acts as a liquid seal, creating a slight pressure difference between the gas phases of the two condensers, thereby preventing mixing of the gas phases.
A liquid seal is formed to prevent the uncondensed gas phase from coming into direct contact with the rear end; however, in the lower-stage condenser, it is discharged directly.
There is gas inside the PG pipeline; this might be for liquid sealing purposes. Normally, a reverse U-shaped pipeline is used, and a ball valve is employed when draining it
Similar structures have been used in flash tanks before to maintain a certain liquid level; under normal operation the valve remains closed, and the liquid level inside the equipment must reach the top of the marked mark before it can overflow. For drainage and maintenance, open the valve below to drain the equipment completely.
