Problems solved by technology

Therefore, inert gases such as neon or argon must be used in the waste heat recovery process, which leads to the complexity of the system and must be closed, and it is difficult to solve the bonding of the molten calcium carbide cooling process to the wall, the damage of high temperature to the material, and the short-term difficulty after failure. Application problems such as repair, powdering and deterioration of calcium carbide products, and poor heat utilization caused by poor continuity of baked calcium carbide

Abstract

A method for energy utilization in the production process of calcium carbide in the technical field of energy saving and environmental protection, comprising the following steps: first, a transport vehicle carries molten calcium carbide contained in a crucible into a cooling workshop, and waits until the calcium carbide begins to solidify; second, the calcium carbide solidifies Then, the mechanical drill bit is used to feed the pre-drilled hole from the top to the solidified calcium carbide center, and then the mechanical drill bit is withdrawn. Superconducting materials transfer heat to heat-consuming devices through flexible superconduits. In the present invention, the heat extraction process is distributed, which solves the problem of discontinuous heat consumption caused by the discontinuous firing of calcium carbide; at the same time, the present invention does not affect the original firing process, and completely solves the bottleneck of calcium carbide production energy to achieve rapid Taking heat does not affect the quality of calcium carbide products.

Description

technical field [0001] The invention relates to an energy utilization method in the technical field of energy saving and environmental protection, in particular to an energy utilization method in the calcium carbide production process which adopts a flexible superconduit to transfer heat to heat-using equipment. Background technique [0002] The calcium carbide production industry is an industry with high energy consumption and high pollution. In the traditional calcium carbide production, when the calcium carbide is released from the furnace, the furnace trolley carries the crucible, and the traction device leads the crucible to the calcium carbide furnace outlet. Calcium carbide flows into each crucible in a molten state, and the temperature of the liquid calcium carbide at this time is up to 2000°C. After the furnace is finished, the crucible filled with calcium carbide melt is pulled into the cooling workshop for cooling. When the outer surface temperature drops to about...
