Problems solved by technology

[0004] CN103752593A discloses a process for the selection and recovery of heavy metals in domestic waste incineration slag, in which the metal and nonmetal in the slag are separated by three-stage separation equipment of iron remover, magnetic separator and jig, but the process is relatively Simple, the recovery rate of metal is only about 70%. Although the remaining slag after metal recovery can also be used to prepare building materials, the strength of the prepared bricks is not high.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.

[0032] As shown in the figure: a domestic waste incineration power generation furnace slag wet resource utilization system, which includes a slag storage system 1, a slag feeding system 2, a slag sorting system 3, a slag magnetic separation system 4, an iron treatment system 5, a Magnetic metal treatment system 6, sewage treatment system 7.

[0033] The slag storage system 1 is the slag storage area. The slag is transported to the slag storage area by vehicles. The slag storage area includes the storage area and the spray deodorization system, ultraviolet light system and bag dust removal system installed in the storage area;

[0034] Spray deodorization system: Spray aromatic deodorant in the storage area to neutralize the odor of slag and adjust the moisture content of slag.

[0035] Ultraviolet light system: irradiate with ult...

Abstract

The invention discloses a wet method resource utilization system for domestic waste incineration power generation furnace slag, which comprises a slag storage system, a slag feeding system, a slag sorting system, a slag magnetic separation system, an iron treatment system, a non-magnetic metal treatment system, sewage Treatment system; a wet-process resource utilization system of domestic waste incineration power plant slag according to the present invention, which can effectively separate and extract various metals in the slag, realize resource utilization, and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of domestic waste treatment, in particular to a wet method resource utilization system for domestic waste incineration power plant slag. Background technique [0002] Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and turning it into residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals and organic pollutants from being discharged into the environmental medium again. Recycling the heat generated by garbage incineration can achieve the purpose of recycling waste. Garbage incineration is an older and traditional method of garbage disposal. After incineration of garbage, the reduction effect is remarkable, the land is saved, and various pathogens can be eliminated, and toxic and harmful substances c...
