Seek advice on the precautions for using a sulfuric acid diluter.

Steps for using the sulfuric acid diluter now: First, feed clean water into the mixer of the sulfuric acid diluter for a few seconds to establish a constant flow rate. Restart the sulfuric acid pump and maintain a constant flow rate; use the previously calculated volume ratio to set up the operation with the fixed amount of sulfuric acid. Abnormal conditions have occurred: 1. Severe pressure buildup in the mixer of the sulfuric acid diluter; 2. High temperature in the mixer: sometimes exceeding 200 degrees. 3 causes the mixer graphite to turn into powder. I hope an expert can give some advice.
Made of PTFE material; it’s still fine after a year of use.
Our company also uses sulfuric acid diluters, and we haven’t encountered the problem you mentioned; it’s possible that the size you selected is too small.
The concentration decreased from 98% to 52%
Check whether the area of the diluter matches its production capacity, carefully adjust the ratio of concentrated sulfuric acid to deionized water, and ensure that the cooling water in the jacket of the upper tank is circulating properly.
