Lime-calcium carbide co-production system and method
The invention discloses a lime-calcium carbide co-production system and method. The lime-calcium carbide co-production system comprises a calcium carbide waste heat recovery unit, a calcium carbide furnace tail gas recovery unit and a lime kiln tail gas utilization unit. The calcium carbide waste heat recovery unit realizes rapid cooling and heat recovery of high-temperature molten calcium carbideby using a furnace mouth annular barrel granulation heat collection mechanism; the calcium carbide furnace tail gas recovery unit introduces calcium carbide furnace tail gas into a carbon material drying furnace to dry semi-coke and then introduces the semi-coke into the lime kiln as fuel; the lime kiln tail gas utilization unit uses a cyclone dust collector to conduct dust falling treatment on lime kiln tail gas and then heats lime kiln raw material air through a heat exchanger. Directed at the calcium carbide production industry, gradient utilization of heat energy in an actual applicationprocess and special treatment requirements of molten state calcium carbide are comprehensively considered by the invention, lime production and calcium carbide production are combined through organiccombination of a plurality of units and optimization of the structure and process of the waste heat/gas recovery device, waste heat/gas generated in the production process is fully utilized, and efficient improvement and perfection of a calcium carbide production system are achieved.
本发明公开了一种石灰‑电石联产系统及方法，包括电石余热回收单元，电石炉尾气回收单元，石灰窑尾气利用单元。电石余热回收单元使用炉口环形筒粒化集热机构实现高温熔融态电石的快速冷却和热量回收；电石炉尾气回收单元将电石炉尾气通往炭材烘干炉烘干兰炭后作为燃料通入石灰窑；石灰窑尾气利用单元使用旋风除尘器将石灰窑尾气降尘处理后，经换热器对石灰窑原料空气进行加热。本发明针对电石生产行业，综合考虑实际应用过程中热能的梯级利用，以及熔融态电石存在的特殊处理要求，通过多个单元的有机组合，优化废热/气回收装置结构和流程，将石灰生产与电石生产相结合，充分利用生产过程中产生的废热/气，实现电石生产系统的高效改进和完善。
