How to repair and clean the circle of lime adhesion in the lime shaft kiln
Lime shaft kiln is a key equipment in the limestone calcination process, and its efficient and stable operation is crucial for ensuring production efficiency and product quality. However, the problem of ring formation inside the kiln has always been a challenge for many manufacturers. Circling not only affects the ventilation inside the kiln, resulting in uneven temperature distribution, but also increases energy consumption, reduces production efficiency, and in severe cases can even lead to equipment failure, affecting the normal operation of the production line. Introduce the maintenance and cleaning methods for the ring formation inside the lime vertical kiln to address this issue.
1、 Cause analysis
Firstly, it is necessary to conduct a thorough analysis of the reasons for the formation of circles inside the lime vertical kiln. Common reasons include fluctuations in material composition, unstable feeding, improper temperature control, and poor ventilation inside the kiln. In addition, the high content of harmful components such as sulfur, chlorine, and alkali in raw materials, large fluctuations in coal powder quality, and uneven mixing of kiln ash may also lead to agglomeration.
2、 Maintenance and cleaning methods
Stable material composition and feeding amount: By optimizing the material ratio, the stability of the material composition is ensured, and the feeding amount is also stabilized to make the thickness of the material layer suitable and reduce the possibility of ring formation.
Adjust temperature control parameters: Based on the temperature distribution inside the kiln, adjust the temperature control parameters reasonably to avoid local temperatures being too high or too low, in order to reduce the formation of rings.
Strengthen ventilation inside the kiln: optimize the ventilation system to ensure smooth air circulation inside the kiln and reduce ring formation caused by poor ventilation.
Cleaning of Circles: For already formed knots, methods such as using a mobile alloy scraper, adding fuel burning adhesive, or changing the high-temperature zone can be used for cleaning. During the cleaning process, ensure safe operation and avoid damage to the kiln body.
Regular inspection and maintenance: Regularly inspect and maintain the lime shaft kiln, including the appearance of the kiln body, whether there are cracks or deformations in the kiln shell, and whether the equipment connection parts are fastened, to ensure that the equipment is in good condition.
The maintenance and cleaning of the ring inside the lime shaft kiln is a systematic project that requires multiple aspects to be addressed. By stabilizing the material composition and feeding amount, adjusting temperature control parameters, strengthening ventilation inside the kiln, cleaning up ring materials, and conducting regular inspections and maintenance, the problem of ring formation inside the lime shaft kiln can be effectively solved, improving equipment operating efficiency and product quality, and creating greater economic benefits for the enterprise.
