Abstract

The invention relates to the technical field of buoyancy separation and particularly relates to a buoyancy separation and recovery system and method for garbage incineration slag. The system comprisesa slag crusher, a mixing stirring tank, a first water pumping mechanism, a flotation worktable, a flotation barrel, a rotary driving mechanism, a spiral cam mechanism, a bottom discharging mechanismand a second water pumping mechanism. The flotation barrel is suspended in the middle of the flotation worktable and is fixedly installed at the working end of the rotary driving mechanism. The feeding end of the first water pumping mechanism is arranged inside the mixing stirring tank, the discharging end of the first water pumping mechanism is suspended inside the feeding port of the flotation barrel, the feeding end of the bottom discharging mechanism is elastically connected to the discharging port of the flotation barrel, and the feeding end of the second water pumping mechanism is arranged inside the flotation barrel. The buoyancy separation and recovery system and method for garbage incineration slag have high efficiency, high recovery rate, low noise and no dust pollution.

Description

technical field [0001] The invention relates to the technical field of buoyancy separation, in particular to a system and method for buoyancy separation and recovery of waste incineration slag. Background technique [0002] my country's metal smelting waste slag has a huge annual output and accumulation, and is one of the worst-utilized bulk solid wastes. Taking iron and steel smelting as an example, my country's steel output in 2014 and 2015 both exceeded 1.1 billion tons, and the cumulative output in the past ten years has reached 8 billion tons. The accompanying annual output and accumulation of steel slag is huge, and it is one of the worst bulk solid wastes used by iron and steel enterprises. Corresponding to the steel production, my country produces nearly 100 million tons of steel slag annually, and currently has a cumulative stockpile of nearly 1 billion tons of steel slag, which is a huge crystalline carbon resource pool. During the smelting process, the excess ca...
