Can the regenerator be unloaded without vacuum?
Thread Content
The regenerator pressure is over 200 kPa; in principle, it should be possible for the material to reach the waste agent tank under its own pressure. Normally, when fresh agent is collected, the pressure is around -60 kPa. Is this theory feasible?
Is vacuum pumping required to unload the regenerator? We have never done it; to discharge the material, just turn on the conveying air and open the discharge valve
After we stopped production, we used vacuum pumping to remove the catalyst, which was much more efficient! Insert a steel wire lined tube at the end of the short pipe, and just suck it like a vacuum cleaner!
So what’s the desizing speed? Is the temperature easy to control?
I’m considering ways to make the device more energy-efficient; maybe using wind instead of steam could save energy, but I’m not sure about the speed aspect
If shutting down, vacuuming can be considered to ensure thorough unloading； There’s no need to evacuate the vacuum under normal circumstances. Wasting steam.
It is easy to control; the opening degree of the desolvant valve can be adjusted based on the temperature on the desolvant line. We keep the desolvant temperature in the regenerator at no more than 480 degrees
When draining the fluid under normal conditions and the pipeline causes discomfort, vacuum pumping can be used; during shutdowns, vacuum pumping can help to drain the fluid more quickly, but it is not necessary at other times.
