Calcium carbide cooling device and method

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.

AI Technical Summary

Problems solved by technology

This method solves the problems of long time-consuming cooling of calcium carbide, large area occupation, and low cooling efficiency to a certain extent. However, in the actual operation of the system, due to the possible leakage of nitrogen gas, it is necessary to continuously replenish nitrogen gas into the cooling system, which increases the system cost. The investment cost reduces the operating economy; in addition, although the nitrogen activity is low, its chemical properties are unstable under high temperature conditions, which affects the safe and stable operation of the cooling system
