Problems solved by technology

The conventional slag treatment method is to transport it to landfill or burn it into tiles, but there are a lot of heavy metals or non-ferrous metals in the slag, landfill will cause land pollution, and firing into tiles will also affect human health

Embodiment Construction

[0010] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings and examples.

[0011] The invention is a slag treatment process, which is specially used for the treatment process of slag produced after domestic waste incineration. The process flow of the treatment method is as follows: figure 1 Shown:

[0012] First of all, the slag produced after the incineration of domestic waste is sent to the wet sand making machine through the belt conveyor, and the wet sand making machine will fully break up hard substances such as sintered slag blocks, stones or concrete blocks below 100 mm in the slag. into fine slag, a magnetic separator is installed above the belt conveyor, which can recycle large pieces of metal;

[0013] Then, these fully crushed fine slags are sent into the saw-tooth wave jig, which can fully settle the heavy metal particles in the fine slag, and discharge them to the shaker through the pip...

Abstract

The invention relates to a slag treatment process; slag is conveyed into a wet sanding machine by a belt conveyor, and is fully broken into fine slag, then the fully broken fine slag is conveyed into a sawtooth wave jigger, metal heavy particulate matters are discharged to a shaking table via a pine by the sawtooth wave jigger, light particulate matters free of metals are directly discharged to a slag stacking area, the metal heavy particulate matters are further screened to obtain metal heavy particles, light particulate matters and wastewater on the shaking table, the treated wastewater can be recycled, the light particulate matters are sent to the slag stacking area, the slag in the slag stacking area can be used for making bricks; and the slag treatment process can be used in waste slag processing operations of waste incineration engineering.

Description

technical field [0001] The invention relates to a process for treating slag, in particular to a process for treating slag produced after domestic garbage is incinerated. Background technique [0002] Slag is the residue after incineration of domestic waste. The water-cooled slag after high-temperature incineration is a dense and sterile residue with stable chemical properties. It is mainly composed of silica, silicate and calcium compounds, and its chemical composition is very stable. . It is listed as general solid waste in the "Standards for Pollution Control of Domestic Garbage Incineration (GB18485-2001)". The conventional slag treatment method is to transport it to landfill or burn it into tiles, but there are a lot of heavy metals or non-ferrous metals in the slag, landfill will cause land pollution, and firing into tiles will also affect human health. Therefore, there is a need for a slag treatment process to make the slag more environmentally friendly and more valu...
