Questions about several high slots

So why is the Na2SO3 used in the electrolysis section not designed to be added in a high-level tank? Can you please share your opinion? # hcbbs
Just look at the pressure at the place where sodium sulfite is added. The salt water is added at a time to places with very low pressure, haha
The electrolyzed sodium sulfite is added to the outlet of the dechlorinated light brine pump, and the pressure is relatively high. If a high-level tank is used, how high a high-level tank is needed to add it?
We are adding it to the inlet of the pump, so we should be able to use a high-level tank.
What we add here is at the inlet of the pump. We also use a pump to add this. It’s hard to say. If you use a high-level tank, you must use the pump to reach the high level. In fact, it is the same.
The sodium sulfite of primary brine is also pumped here. Wouldn't it be a waste to add a high slot here?

If the high-level tank is added, the flow rate will be more stable. For electrolytic addition of acid, pure water, and sodium sulfite, high-level tanks are not designed because of pressure issues. If combined with Venturi, high slots can still be designed.
Logically speaking, if sodium nitrate is added at the inlet of the pump, there should be no problem! Think about it, although the dechlorination tower has negative pressure and the high-level tank is facing the air, there is enough liquid column to ensure the pressure. There is a negative suction pressure at the pump inlet and it changes with the regular fluctuations of the brine flow rate. It is also easy to control with a high-level tank. If a high-level slot is specially set up, the investment will be a little more, but the operation should be more economical. Of course, if the demand is too large, there will not be much advantage. The so-called savings are the electricity costs of starting and stopping the pump intermittently.
Energy saving. I think everyone has ignored the issues of flow control, labor costs and safety hazards in lifting materials to high-rise buildings.
Using a pneumatic diaphragm pump plus sodium sulfite has better results.
It can be added by pump, and the method of high-level tank addition is generally not considered. The first salt part requires a precise addition amount. Excessive or insufficient addition of the refined preparation will have an impact on the electrolytic tank, so a high-level tank is used to add it. After electrolysis, the requirements for adding sodium sulfite to light brine are not so precise, and in order to meet the process requirements, the high-level tank requirements are relatively high.
