Stirring in the front and rear reaction tanks

Compressed air can be used for stirring; our company uses mechanical stirring, but when there are problems with the stirrer, we resort to using compressed air for stirring, and the results are also good.
Our company uses mechanical stirring, and we also face the problem of frequent equipment repairs; if anyone has good solutions, please share them
We are purchasing mixing machinery (for the brine tank and the post-reactor). Mechanical stirring should be more energy-efficient.
Our company uses it when the mixer malfunctions, and the usage period is generally around two days. I feel like there isn’t a significant change in the effect; maybe it’s because the time period is too short. However, this shows from one aspect that compression air can be used for stirring. However, the specific effects still need further verification.
Compressed air can be used for stirring, but the effect is poor, and it is easy for gas to enter the pump, causing damage to it. Mechanical methods are better.
We use mechanical stirring; in my opinion, the effects of the two methods are similar
Using compressed air for stirring can completely replace mechanical stirring; however, it is important to pay attention to the direction of the airflow in order to maintain the rotation of the liquid. Additionally, the problem of air being drawn into the pump can be completely resolved by modifying the structure at the liquid outlet at the bottom of the tank
We use mechanical stirring, which works very well; occasionally when there is a malfunction and stirring stops, it does not affect the quality of the brine.
Mechanical stirring provides a better mixing effect than compressed air stirring; moreover, air stirring can cause air to dissolve in the saline solution, which may have an impact on subsequent processes!
Hi! Hello, teachers upstairs! I’m very interested after reading everyone’s introductions. Our unit is currently carrying out saltwater modification, and in this process front reaction tanks (φ4200×6500) and rear reaction tanks (φ4200×18000) are being used. We are now working on the mixing system design, and I would like to ask: could you please share the specifications of the front and rear reaction tanks as well as those of the mixers in your respective units? Please help!
I think, of course, mechanical stirring is better than air stirring; air stirring is used as a backup in case mechanical stirring fails. 1. Mechanical stirring is energy-efficient, while air stirring is not. Think about it: air requires power to be used for stirring, so it’s obviously not economical ； 2. A well-designed mechanical stirring system will certainly yield better results than air stirring; of course, using coils in the reaction tank along with air stirring can also achieve good results.
For mechanical stirring, it is essential to ensure proper anti-corrosion measures as well as the use of suitable materials; for air stirring, it is important to achieve a uniform distribution of air currents, as saltwater is highly corrosive
