AI Technical Summary

⚠Technical Problem

The existing ammonia spraying grid purging device cannot effectively adjust the position of the cleaning pipe, resulting in insufficient cleaning of the ammonia spraying grid surface, and the cleaning pipe is easily blocked by dust in the flue gas, resulting in poor performance.

⚗Method used

An air purging device for ammonia spray grid was designed. The angle of the soot blowing pipe and the baffle plate is adjusted by an electric push rod and gear mechanism, so that the jet hole can clean the surface of the ammonia spray grid in all directions. After cleaning, the jet hole is blocked to prevent flue gas from entering the soot blowing pipe.

🎯Benefits of technology

This method achieves thorough cleaning of the ammonia injection grid surface, avoids clogging of the jet nozzles and soot blowing pipes, and improves the effectiveness and reliability of the device.
