The annular cooling suspension cylinder comprises a suspension cylinder body with an annular airflow channel, and a middle partition plate is arranged between an outer side shell and an inner side shell and used for dividing the annular airflow channel into an air inlet channel and an exhaust channel. The spiral screwing-in spiral piece is arranged in the air inlet channel and used for enabling the air inlet channel to form a spiral screwing-in channel, the spiral screwing-out spiral piece is arranged in the exhaust channel and used for enabling the exhaust channel to form a spiral screwing-out channel, an air inlet is formed in the air inlet end of the spiral screwing-in channel, and an exhaust outlet is formed in the exhaust end of the spiral screwing-out channel. And the exhaust end of the spiral screwing-in channel and the air inlet end of the spiral screwing-out channel are mutually communicated and combined to form a spiral cooling channel. According to the annular cooling suspension cylinder for the double-chamber lime kiln, the double-layer spiral sheet type air cooling channel is arranged, so that the resistance of a suspension cylinder cooling system can be remarkably reduced, the cooling effect is improved, and the service life of the lime kiln is effectively prolonged.
Description
[0001] 1In the field of technology [0002] The present invention relates to the technical field of double-chamber lime kiln equipment, and in particular, to an annular cooling suspension cylinder for a double-chamber lime kiln. The invention also relates to a double-chamber lime kiln. 2 Background technology [0003] The double-chamber lime kiln is one of the most advanced lime production equipment currently and is widely used in the production of industrial lime and construction lime. It is mainly composed of two vertical kiln chambers that are mirror images of each other. During the production process, pulverized coal and combustion-supporting air are supplied to one side of the kiln chamber to form a high-temperature environment, causing the limestone in the kiln chamber to decompose at high temperature, which is called a calcining chamber; to the other side of the kiln chamber is a calcining chamber. One side of the kiln chamber is filled with normal temperature material...
