AI Technical Summary
Technical Problem
Existing backflush level gauges are easily damaged by acid backflow in esterification reactors, affecting equipment lifespan and measurement accuracy. Furthermore, liquid backflow at the static pressure end also affects measurement precision.
Method used
One-way valves A and B are installed on the air blowing pipe and static pressure pipe respectively, and a liquid collector and a filter temperature control device are provided to avoid acid water backflow and the influence of temperature difference, and pressure is quickly released through the pressure relief valve.
Benefits of technology
It effectively prevents acid backflow, extends equipment life, improves measurement accuracy and safety, and reduces maintenance costs.
