Problems solved by technology

The disadvantages of this method are: 1. The slurry pump or air lift is easy to wear, and the secondary filtration effect of tiny slag particles is poor, which increases the equipment load
2. In order to prevent the deposition of tiny slag particles, it is necessary to install a stirring water pump or spray compressed air at the bottom of the sedimentation tank. This method increases the concentration of slag sus

Abstract

The invention relates to a furnace slag combined processing system that includes slag branch groove 1, wheel method granulated slag processing device that is made up of granulator, dewater unit, and rubber coated draper, and slag branch groove 2, slag flushing groove, flat flowing granulated slag processing device that is made up of mud settler 1, mud settler 2, cycling pool, and cycling pump. The feature of the structure is that the slag branch groove 1 connects to the granulator, backwater groove on dewater unit connects to mud settler 1, and slag branch groove 2 connects to slag flushing groove that connects to mud settler 1. The invention has the advantages of low channel wear rate, high granulating slag flushing ratio, small floor area, etc. It achieves the effects of environment protecting, high efficiency and energy saving.

Description

Technical field [0001] The invention belongs to the technical field of metallurgical ironmaking equipment, and particularly relates to a blast furnace slag processing system. Background technique [0002] At present, domestic and foreign ironmaking enterprises generally treat blast furnace slag by advection method (conventional flushing method), INBA method and wheel method. Among them, the advection method (conventional flushing method) has the advantages of simple structure and high slag flushing rate, but it has a large area, mechanization, low automation, large energy consumption for long-distance transportation of slag-water mixture, and greater environmental pollution. The INBA method and the wheel method have the advantages of high degree of mechanization, good environmental protection, small circulating water, low power consumption and high system safety; however, due to the INBA method and the wheel method, the filter screen produced during the slag flushing process The ...
