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

The invention relates to an energy utilization method in a calcium carbide production process, and belongs to the technical field of energy conservation and environmental protection. The energy utilization method comprises the following steps that 1, a transport vehicle carries molten calcium carbide contained in a crucible to enter a cooling workshop, and waits until the calcium carbide begins tosolidify; 2, after the calcium carbide is solidified, a mechanical drill bit is used for feeding pre-drilled holes from the upper portion to the center of the solidified calcium carbide, and then themechanical drill bit is withdrawn; 3, a mechanical arm drives a superconducting pipeline to be arranged in the pre-drilled holes through a clamp; and 4, superconducting materials in the superconducting pipeline transmit heat to heat using equipment through a flexible superconducting pipe. According to the energy utilization method, the heat taking process is distributed, so that the problem of discontinuous heat consumption caused by discontinuous calcium carbide discharging is solved; and meanwhile, the original discharging process is not affected, the choke point of calcium carbide production energy is thoroughly solved, rapid heat taking is achieved, and the quality of calcium carbide products is not affected.
Description
technical field [0001] The invention relates to an energy utilization method in the technical field of energy conservation and environmental protection, in particular to an energy utilization method in the calcium carbide production process that uses a flexible superconductor to transfer heat to heat-using equipment. Background technique [0002] The calcium carbide production industry is a high energy consumption and high pollution industry. In the traditional calcium carbide production, when the calcium carbide is released from the furnace, the furnace trolley carries the crucible, and the crucible is led to the calcium carbide furnace outlet by the traction device. Calcium carbide flows into each crucible in a molten state, and the temperature of liquid calcium carbide at this time is up to 2000°C. After leaving the furnace, pull the crucible full of calcium carbide melt into the cooling workshop for cooling. When the outer surface temperature drops to about 400°C, the ca...
