Calcium carbide cooling device and method thereof

Abstract

The invention relates to a calcium carbide cooling device and method. The calcium carbide cooling device comprises a calcium carbide cooling tower. A sand inlet is formed in the upper end of the calcium carbide cooling tower, and a sand outlet is formed in the lower end of the calcium carbide cooling tower. A cooling pan track is arranged in the calcium carbide cooling tower. A closed type cooling pan used for containing calcium carbide is placed on the cooling pan track. The sand inlet and the sand outlet of the calcium carbide cooling tower communicate with a sand transfer system, so that a sand transfer loop is formed. The cooling device adopts sand as a cooling medium. Mobility of the sand and gravity of the sand are utilized to form forced convection with the calcium carbide cooling pan, so that cooling is accelerated, and time for cooling consumption is effectively shortened. Investment cost of cooling equipment is reduced to a great extent. Occupied space is reduced. Operation safety stability and economy are improved. The problems that much time is consumed and occupied space is large in the traditional calcium carbide cooling process are solved. Meanwhile, sand circulation is completed by means of the sand transfer system, the speed of the sand transfer system is adjusted and the calcium carbide cooling effect can be effectively controlled.

Description

[0001] 【Technical field】

[0002] The invention relates to the field of calcium carbide cooling, in particular to a calcium carbide cooling device and a method thereof.

[0003] 【Background technique】

[0004] With the advancement of science and technology, the organic synthesis industry has developed rapidly, and calcium carbide as a main raw material in the organic synthesis industry has attracted much attention. Human demand for calcium carbide is also increasing year by year. , Intensive transformation. Since the 21st century, my country's calcium carbide industry has entered a period of rapid growth in production capacity, with an annual growth rate of 20%. By 2006, my country's calcium carbide production reached more than 10 million tons, and by the end of 2012, the production capacity reached 32.3 million tons, and the output increased. To more than 20 million tons, the output ranks first in the world.

[0005] Although calcium carbide has a wide range of application ma...
