The regeneration tank level regulator cannot be adjusted
Thread Content
As the title says. During work, it was found that the liquid level in the regeneration tank was too high, causing it to overflow the overflow weir. The level regulator (sleeve type) could not be used effectively to adjust this level; whether the regulator was set to a higher or lower position, its effect on the regeneration tank was minimal, and within less than five minutes the foam once again covered the overflow weir. It was expected that reducing the height of the overflow port of the level regulator would lead to a decrease in the level of the regeneration tank; in reality, however, the level of the regeneration tank remained almost unchanged. The level of the lean liquid tank increased briefly before declining slowly, while the level of the rich liquid tank rose rapidly. Later, the level of the regeneration tank could only be reduced by lowering the circulation volume. There is no distinction between early and late in learning; those who have achieved mastery are the teachers. I’m seeking advice from a senior to figure out where the problem lies
…I think I know what’s going on; I’ll explain it downstairs
It’s not that reason; it’s impossible. What about the export pipelines worth 700,900?
That day, it was suspected that there was a problem with the level regulator; possibly the inner tube of the sleeve-type level regulator had fallen into place and blocked the outlet for the clear liquid from the regeneration tank. The thin tubes were originally designed to be long enough, but department managers approved a reduction of 400 units in their length, resulting in tubes that are too short. This limits the effective adjustment range; when the liquid level is lowered, it blocks the outlet for clear liquid, reducing flow rate, and when the level is raised, it is not possible to effectively increase the liquid level in the regeneration tank. In short, it’s the failure of the level regulator in the technical modification
Is the pipe blocked? Or the control valve is in the closed position and cannot be opened
Original poster, has the problem been solved now? What was the reason identified later? Please provide an update on the progress, thank you for your support
Since there is a control valve, why not first switch to the bypass line for adjustment and then switch off the control valve to check for the cause?
