Description

Kiln slag treatment system Technical Field The utility model relates to the field of melting furnaces, in particular to a furnace slag treatment system. Background Melting furnace melting treatment is a main mode for recycling and treating solid waste, the solid waste is melted at high temperature in the furnace, organic matters and the like are combusted and decomposed, heavy metals and the like are melted in slag, and the slag is collected and then further separated and purified. The traditional slag treatment mode is slag pool water quenching, a locomotive is used for pulling a slag tank beside a pool, a surface slag shell is smashed, slag is slowly poured into the pool, and the slag is rapidly cooled into granular water slag when meeting water. The water slag is grabbed out by a crane and placed in a slag stacking field, and is loaded and transported outside after dehydration. The method has simple and reliable process equipment and low water consumption, but can generate a large amount of steam, slag cotton and H2S gas, and has serious environmental pollution. Disclosure of Invention The utility model provides a furnace kiln slag treatment system for solving the pollution and the influence of vapor and slag cotton generated in the slag quenching process in the prior art on the environment. The technical scheme adopted by the utility model is as follows: The furnace slag treatment system comprises a slag pool unit, a cooling water circulation unit and a slag discharging unit, wherein the slag pool unit comprises a water quenching slag pool and a closed slag pool, cooling water is filled in the water quenching slag pool, the closed slag pool comprises a circle of concrete wall body arranged on the outer side of the top of the water quenching slag pool, the concrete wall body seals the water quenching slag pool and is provided with an opening at the top, the water quenching slag pool is positioned on one side of a melting furnace, a slag discharging chute is arranged on one side of the melting furnace, penetrates through the concrete wall body on one side of the closed slag pool and is led into the water quenching slag pool, the slag discharging chute is connected with the cooling water circulation system, a circle of light wall body is built on the top of the closed slag pool, four side surfaces of the light wall body correspond to the closed slag pool, a flat platen is arranged on the top of the light wall body, a vertical air pipe is arranged at the center opening of the flat platen, a wet electric demister is arranged on the top of the air pipe, the slag discharging unit comprises a travelling crane suspended slag storage bin and a travelling crane, two temporary storage holes are arranged on the outer side of the travelling crane bin, and a water door is arranged on the outer side of the travelling crane bin and is provided with a closed door, and a water door is arranged at the outer side of the travelling crane bin.
