The kiln air system is one of the important brick-making equipment, and its working quality and performance directly affect the brick-making process and output. In order to ensure the normal operation and maintenance of the kiln air system, it is necessary to formulate corresponding upgrading and maintenance strategies. This paper will analyze the strategy of kiln air system from two aspects: equipment upgrade and maintenance.

Equipment upgrading is an important means to ensure the efficiency and quality of kiln air system. You can consider upgrading the kiln fan. By replacing a new and efficient fan, the air volume and pressure of the fan can be improved, thus improving the ventilation effect of the kiln air system, reducing the emission of smoke and particles and reducing energy consumption. Secondly, we can consider upgrading the kiln tuyere. When selecting a new tuyere, its hydrodynamic performance and smoke tightness should be considered to improve the combustion efficiency of the kiln and the uniformity of pulverized coal combustion. In addition, we can consider adding a new control system to realize the automatic control and optimal adjustment of the kiln air system and improve the stability and production efficiency of the kiln.

Maintenance is the key to ensure the long-term stable operation of kiln air system. Regular inspection and maintenance of equipment should be carried out. Regularly check the working status and connection of fans, tuyeres, pipelines and other equipment, and timely clean up dust and sundries to prevent blockage and resistance increase. At the same time, it is also necessary to maintain and inspect related power distribution systems, control systems and other equipment to ensure their normal operation. Secondly, we should pay attention to the lubrication and maintenance of equipment. Add proper amount of lubricant to the bearing and lubrication parts of the fan regularly to reduce wear and friction and prolong the service life of the equipment. In addition, the dynamic balance and vibration detection of the equipment should be carried out regularly to ensure the normal operation of the equipment and not to produce excessive vibration. It is necessary to strengthen the training of personnel and upgrade their maintenance skills. Strengthen the training of kiln air system equipment, improve the maintenance skills and professional knowledge of staff, and enhance the equipment maintenance ability, so as to prevent in advance, maintain in the process and summarize afterwards.

The upgrading and maintenance strategy of engineering equipment of kiln air system is very important to ensure its normal operation and prolong its service life. By upgrading the equipment, the working efficiency and quality of the kiln air system can be improved; Through maintenance, the long-term stable operation of the equipment can be guaranteed. Therefore, when formulating the upgrade and maintenance strategy, we should consider the content, method and cycle of equipment upgrade and maintenance, and also pay attention to the training of personnel and the improvement of maintenance skills to ensure the continuous and stable operation of the kiln air system and meet the requirements of brick-making technology.
