During resin regeneration, the pressure reaches 2 kilograms at one point

There shouldn’t be any; we have a process procedure for the resin to be blown back by the compressor, but it’s not guaranteed to work. Please offer more guidance
What is the process? Normally, don’t we monitor the pressure difference in the resin bed? As long as the pressure difference is not high, it won’t have an impact on the resin.
2 kilograms for the regeneration process? ? The pressure must be a bit too high! 2 kilograms is no problem during operation! :lol Last edited by 181128425 on 2009-4-4 17:34 ]
There should be no problem; the pressure is sometimes 2 Kg during regeneration, and it reaches around 4.2 Kg during operation, and there isn’t much broken resin either. But note that pressure is also necessary; after all, too much pressure isn’t good either!
During regeneration, there are two types: bubbling pressure and drainage pressure； Excessively high pressure during bubbling may affect the breakdown of the resin or damage the filter cap; worse still, it can cause the resin to be carried out of the resin tower, thereby reducing the resin loading capacity and leading to a decrease in regeneration capacity. Excess pressure during drainage can cause the entrained resin to be lost, or the resin remaining in the pipeline valves can cause them to stick, thereby affecting their functionality. Therefore, attention must be paid to pressure control during this process.
When regenerating the resin in our factory, the amount can reach over 2 kilograms as well; sometimes liquid leaks out through the sight glass, which suggests that it’s time to replace the resin.
If the pressure difference in the resin tower is high, the backwash time and backwash flow rate can be increased during regeneration, or it is possible to check whether the resin filter is clogged.
If the pressure is high during regeneration, there may be a blockage of broken resin in the outlet trap; in such cases, the flow rate should be reduced. A low pressure difference should have no effect on the resin.
Is it the pressure inside the tower or the pressure difference? A pressure of 0.2 MPa inside the tower is acceptable.
Is the pressure difference in the resin column high? After high-flow backwashing, what is the situation of the broken resin being flushed out, and how effective is it after observation? If the pressure difference remains high, then switch to single-tower operation separately, and pay attention to flow rate and pressure; it might be caused by clogged valves or pipes.
Resin catchers can cause an increase in the pressure difference across the resin column. The solution is to route the brine around the catcher, disassemble it, clean the filter screen, and then reinstall it. This task requires 3–4 people, and it’s advisable to complete it within one hour; it’s best to have a new filter screen ready in advance so that it can be installed right after disassembly.
It’s very dangerous, as the poster isn’t sure which step in the resin tower regeneration process is causing the problem; this is even more dangerous than high pressure. Therefore, it is recommended that the poster first figure out which regeneration step is at issue, otherwise it will be very risky!
