Description

Technical Field

[0001] The utility model belongs to the technical field of anti-blocking, and more specifically relates to a lime kiln anti-blocking device. Background Art

[0002] Maerz lime kilns offer advantages such as low energy consumption and excellent product quality. During normal operation, the flue gas generated by calcining the lime kiln flows through the middle channel. However, the decomposition of limestone within the kiln produces a large amount of lime powder. Under the influence of the high-temperature airflow, the lime powder, along with mud, sand, and gravel adhering to the limestone surface, enters the middle channel and subsequent channels. Some of the lime powder and gravel tend to adhere to the middle channel and subsequent channels under the influence of high temperatures. When these impurities are high, they can easily cause blockage within the channel, preventing airflow from entering the subsequent regenerator chamber and affecting the normal operation of the kiln. Some Maerz lime kilns have a filter channel installed in the middle channel during operation. This filter channel is fitted with a filter screen, and both ends of the filter channel are bolted to the middle channel. To replace the filter screen or remove the lime powder and gravel, the filter channel must first be removed from the middle channel. However, to improve sealing performance, the gap between the filter channel and the middle channel is small, making it difficult to remove the filter channel from the middle channel and making this operation challenging.
