Embodiment 1

[0023] A method for reprocessing tailings produced after comprehensive treatment of waste incineration slag, comprising the following steps:

[0024] (1) Collect the light slag powder that flows into the slag storage tank after the waste incineration slag has been processed by metal recovery, and then send it to the first rolling cage sieve. The diameter of the first rolling cage sieve is 1.5m, the length is 6m, and the mesh After screening, the tailings with a particle size greater than 0.8cm are sent to the first metal separator for metal aluminum recovery; the magnetic separation strength of the first metal separator is 3500T, and the raw material delivery capacity is about 12 tons / hour, the conveyor belt width is 1.2 meters, and the speed is 3 meters per second.

[0025] (2) The tailings with a particle size of less than 0.8cm are sent to the second rolling cage sieve. The diameter of the second rolling cage sieve is 1.5m, the length is 8m, and the mesh is 0.3cm. into t...

Embodiment 2

[0032] A method for reprocessing tailings produced after comprehensive treatment of waste incineration slag, wherein in step (4), in parts by weight, 6 parts of cement, 105 parts of modified tailings, 6.8 parts of ceramic powder, 4 parts of Sodium sulfate, 0.8 parts 4,4'-dioctyldiphenylamine, 2.3 parts sodium citrate, 0.31 parts triphenyl phosphite and 2.2 parts polyvinyl butyral. All the other technical contents are the same as in Embodiment 1.

[0033] After testing, the steam-cured brick prepared by the invention has a flexural strength of 4.87MPa and a compressive strength of 33.2MPa.

Embodiment 3

[0035] A method for reprocessing tailings produced after comprehensive treatment of waste incineration slag, wherein in step (4), 5.5 parts of cement, 110 parts of modified tailings, 8 parts of ceramic powder, 3.5 parts of sodium sulfate, 0.6 parts of 4,4'-Dioctyldiphenylamine, 1.5 parts sodium citrate, 0.4 parts triphenyl phosphite, and 2 parts polyvinyl butyral. All the other technical contents are the same as in Embodiment 1.

[0036] After testing, the steam-cured brick prepared by the invention has a flexural strength of 5.2 MPa and a compressive strength of 35.1 MPa.

Abstract

The invention provides a retreatment method for tailing materials generated by comprehensive treatment of waste incinerator residues. Multistage screening and sorting steps are set in the retreatmentmethod and are used for efficiently recovering metallic aluminum in the tailing materials; meanwhile, the recovered tailing materials are specifically modified and can be used for producing baking-free bricks, so that recycling rate and resource recovery rate of wastes are improved.

Description

technical field [0001] The invention relates to the technical field of garbage recovery and reuse, in particular to a method for reprocessing tailings produced after comprehensive treatment of garbage incineration slag. Background technique [0002] Slag is a by-product of domestic waste incineration, including incineration residue remaining on the grate and particulate matter falling from between the grates. Slag consists of slag, bricks, glass, ceramics, stones, metals and organic matter. If you want to comprehensively utilize slag, you need to screen and classify it, and recycle useful metal materials to obtain high value-added products. [0003] CN105195313A discloses a method for recovering metals and combustibles from domestic waste incineration slag. The method realizes the separation of magnetic metals in slag through multi-stage gradient magnetic separation, uses two-stage eddy current separation to recover non-ferrous metals in slag, and finally , The magnetic se...
