AI Technical Summary

Technical Problem

Existing pickling spray towers cannot adjust the amount of alkali solution added in real time when treating waste gas, which affects the treatment effect. Furthermore, the spray pipes are inconvenient to clean, resulting in low work efficiency.

Method used

An alkaline spray pipe and a pH detector are installed inside the pickling spray tower. The opening of the alkaline flow valve is adjusted in real time by a controller to automatically adjust the alkaline spray volume. The pickling spray pipe and the alkaline spray pipe are designed in a cross structure to ensure uniform spraying. At the same time, a cleaning liquid delivery device and a solenoid valve are installed to clean the spray pipes.

Benefits of technology

It enables automatic adjustment of alkaline solution spray volume based on pH value, improves waste gas treatment effect, ensures spray uniformity, simplifies the cleaning process of spray pipes, and improves work efficiency.
