Embodiment 1

[0039] A method for resource utilization of waste incineration slag, comprising the following steps:

[0040] (1) Preparation of waste incineration slag into slag sand products, specifically:

[0041] (1.1) The garbage incineration slag is transported by a special transport vehicle to the designated storage room, from the storage room through the loader to the vibrating feeder (preferred vibrating feeder screen size 1500*4000, motor power 2*2.2 KW, processing capacity 10-40t / h), the vibrating feeder is mainly to remove the lumps with too large particle size.

[0042] (1.2) Drop the remaining slag from the lumps removed in step (1.1) directly into the crusher (preferably jaw crusher model: PE250*400), and crush the slag to 40-100mm.

[0043] (1.3) The slag in step (1.1) is transported to the iron remover (preferred model: RCYD(C)-6.5) through the first conveying belt, and the iron materials are separated, and the iron materials are collected by the collector.

[0044] (1.4) T...

Abstract

The invention discloses a method for resource utilization of waste incineration slag. The method comprises the following steps: sieving waste incineration slag, removing lumps, crushing the sieved waste incineration slag to 40 mm to 100 mm, separating and recovering iron substances in the crushed waste incineration slag, and crushing the waste incineration slag without the iron material until theparticle size is smaller than or equal to 4.75 mm to obtain a slag sand product. According to the method, the waste incineration slag can be prepared into a slag sand product meeting the requirements,the waste incineration slag can be effectively treated, useful metal substances can be recycled, the consumption of river sand in construction engineering can be reduced, and the method has the advantages of simple process, convenience in operation, low cost, high resource utilization rate, no secondary pollution and the like, and has very high use value and very good application prospect.

Description

technical field [0001] The invention relates to a method for resource utilization of waste incineration slag. Background technique [0002] Waste incineration slag is mainly used for brick making or landfill disposal, while slag is used to make bricks directly as building materials, which generally have higher requirements for strength, and the processed finished products are difficult to meet the requirements of high-rise building bricks, and can only be used General sporadic engineering construction with low structural safety requirements, so under the current technical conditions, it is difficult to realize the full processing of incineration slag as building materials to realize resource utilization, so most of the waste incineration slag in major cities still use landfill disposal, landfill The disposal takes up a lot of land resources, and the metal substances contained in the slag are buried together without secondary utilization, which is very wasteful. According to...
