摘要: 以广东省某10 000 t/a固体废物处置系统等离子体熔融炉为例,通过搭建水力学模型试验台,对危险废物等离子体熔融炉进行辅助喷枪水力学模型试验研究及工业应用。结果表明:随着喷枪负荷的增加,穿透深度、飞溅高度、振幅、物料排出比例逐渐增大;随着喷枪布置高度的增加,穿透深度、飞溅高度、振幅、物料排出比例逐渐减小;与错列布置相比,对称布置方案的穿透深度、飞溅高度、振幅、物料排出比例更小。最终确定原型炉体的辅助喷枪设计方案为喷枪布置高度250 mm、对称布置。根据此方案的现场改造取得了预期效果,等离子体炬电耗降低28.6%,考虑氧气制备后系统电耗降低13.2%,小时运行费用降低9.8%。

Abstract: A plasma melting furnace of a 10 000 t/a solid waste disposal system in Guangdong province was taken as an example, the auxiliary spray gun hydraulic model test and industrial application of the hazardous waste plasma melting furnace were carried out by setting up a hydraulic model test platform. The results showed that as the spray gun load increased, the penetration depth, splash height, amplitude and material discharge ratio gradually increased. As the height of the spray gun arrangement increased, the penetration depth, splash height, amplitude and material discharge ratio gradually decreased. Compared with the staggered layout schemes, the penetration depth, splash height, amplitude and material discharge ratio of symmetrical layout were smaller. Finally, the auxiliary gun design scheme of the prototype furnace body was determined as the gun layout height was 250 mm and symmetrical layout. According to this plan, the on-site renovation achieved the expected effect, with 28.6% reduction in plasma torch power consumption, 13.2% reduction in system power consumption after considering oxygen preparation, and 9.8% reduction in hourly operating costs.
