With the continuous pressure on environmental protection, earth kilns have become the last of kilns. However, vertical lime kilns have become the main battlefield for calcining lime. Although the control and calcination process of lime vertical kiln equipment are more automated and intelligent than traditional lime kiln equipment, calcining The high temperature of lime is a relatively dangerous project, so the precautions for kiln operation should not be relaxed at all. Therefore, Tongjia Industry will share with you the seven key points.
1. In the lime shaft kiln, it is not allowed to burn lazy kilns during the production process of lime shaft kilns, and abnormal phenomena such as duquan kilns, kiln setting up, and core extraction are not allowed. , Four-balanced operating procedures, namely, strong wind and large materials; fast burning, quick cooling, and quick unloading; four-balanced operating procedures, namely, wind and material balance, bottom fire balance, kiln surface balance, loading and unloading balance.
2. The lime shaft kiln must deal with the wind tunnel and wind eye diligently according to the fire workers, so as to achieve large-scale wind production.
3. Requires shallow and dark fire operation, the bottom fire is controlled at about 0.9 meters, not deep or shallow, so as to avoid open flame calcination, to ensure that the kiln temperature is normal, and the heat loss of open flame calcination is too large, resulting in waste of heat. The calcium oxide is high, and the wet material layer is controlled by about 30 cm.
4. The lime shaft kiln is required to watch the fire workers press the side fire and raise the middle fire operation method. Do not allow wind eyes in the middle and second ribs. Strictly control the wind phenomenon on the kiln surface and require the center to have a flame. Du lower the fabric tube to run wind, so that there is enough air volume in the kiln for calcination.
5. The lime shaft kiln must take over 10 minutes in advance to see the fire workers. Understand the calcination situation in the working kiln and the operation of the equipment. Wear work clothes and slippers in accordance with the regulations.
6. The lime shaft kiln should always pay attention to the fire work. If abnormal phenomena such as collapse, kiln erection, large wind tunnel, etc. are found, emergency measures should be taken immediately, and the supervisor should be reported to the supervisor and related technical personnel for on-site treatment.
7. The lime shaft kiln must be unified in accordance with the pyrotechnics operation method, and the high-standard sintering material can be burnt at high temperature and high output. The ignition loss of the sintering material is controlled within 0.8, and the free calcium oxide is within 3%.
Lime shaft kiln equipment is under continuous research and development, and equipment and technology are constantly being updated. Therefore, the kiln operators in the lime kiln equipment workshop also need to continuously strengthen learning and training. The smarter it is, the simpler it is, but the rigorous spirit of kiln operation requires constant vigilance.
