AI Technical Summary

Technical Problem

In traditional rotary kiln flue gas treatment, high-temperature dust particles easily clog heat exchange devices, and bag filters are prone to burnout, leading to frequent equipment maintenance and reduced efficiency.

Method used

The airflow compression adsorption device uses a combination of settling and tumble zones, and utilizes negative pressure and damping through-hole design to enhance the settling effect of dust particles, avoid filter clogging and easily burnt-out components, and use damping plates and beveled structures to reduce resistance.

Benefits of technology

It significantly improves the dust particle release effect, extends the service life of the equipment, ensures efficient pretreatment of flue gas before it enters the heat exchange device, reduces the frequency of equipment maintenance, and improves the purification effect.

Abstract

This utility model relates to the field of rotary kiln flue gas purification technology, specifically disclosing a high-efficiency purification device for rotary kiln flue gas. The device includes a main body containing a purification unit. The purification unit, from bottom to top, includes a settling zone and a tumble zone. An airflow compression and adsorption device is installed in the settling zone to compress the initial flue gas and simultaneously direct it into the tumble zone. The airflow compression and adsorption device also includes a return pipe, through which the flue gas in the tumble zone is drawn back and mixed with the initial flue gas. During the backflow process, the flue gas in the tumble zone is guided downwards to enhance the settling effect. An exhaust port is provided at the upper part of the tumble zone. This utility model can significantly improve the purification effect on rotary kiln flue gas, without causing blockage and significantly extending its service life.
