Embodiment 1

[0015] The brick-making process of the solid waste or hazardous waste treatment of the present embodiment comprises the following steps:

[0016] a-Material selection: Select metal solid waste or hazardous waste containing soil (such as copper-containing materials) as the main raw material, and crush it through a crusher;

[0017] b-mixing material: batching is carried out according to weight percentage, wherein, 60% of solid metal waste or hazardous waste material obtained in step a, 20% of iron powder, stir the batching evenly, then add 20% of water, and stir evenly again;

[0018] c-Brick making: transport the material obtained in step b to a brick making machine for pressing to obtain shaped bricks;

[0019] d-curing: curing the formed brick obtained in step c for 3 days under natural conditions, and the finished product is obtained after the water evaporates.

Embodiment 2

[0021] The brick-making process of the solid waste or hazardous waste treatment of the present embodiment comprises the following steps:

[0022] a-Material selection: Select metal solid waste or hazardous waste containing soil (such as copper-containing materials) as the main raw material, and crush it through a crusher;

[0023] b-mixing material: batching is carried out according to weight percentage, wherein, the solid metal waste or hazardous waste material obtained in step a is 70%, iron powder 15%, the batching is stirred evenly, then add 15% water, and stir again;

[0024] c-Brick making: transport the material obtained in step b to a brick making machine for pressing to obtain shaped bricks;

[0025] d-curing: Curing the formed bricks obtained in step c for 2.5 days under natural conditions, and obtaining finished products after the water evaporates.

Embodiment 3

[0027] The brick-making process of the solid waste or hazardous waste treatment of the present embodiment comprises the following steps:

[0028] a-Material selection: Select metal solid waste or hazardous waste containing soil (such as copper-containing materials) as the main raw material, and crush it through a crusher;

[0029] b-mixing material: batching is carried out according to weight percentage, wherein, the solid metal waste or hazardous waste material obtained in step a is 70%, iron powder 20%, the batching is stirred evenly, then add 10% water, and stir evenly again;

[0030] c-Brick making: transport the material obtained in step b to a brick making machine for pressing to obtain shaped bricks;

[0031] d-curing: Curing the formed bricks obtained in step c for 2 days under natural conditions, and obtaining finished products after the water evaporates.

[0032] In the above-mentioned embodiments, since different amounts of iron powder are added to the bricks, the ...

Abstract

The invention provides a brickmaking process capable of achieving solid waste or dangerous waste treatment. The process comprises the steps of a, material selection, wherein metal solid waste or dangerous waste materials containing soil are selected as main raw materials and crushed with a crusher; b, blending, wherein blending is conducted according to weight percentage, 60-70% of metal solid waste or dangerous waste materials obtained in step a and 15-20% of iron powder are evenly stirred, then 10-20% of water is added, and uniform stirring is conducted again; c, brickmaking, wherein materials obtained from step b are conveyed to a brickmaking machine to be pressed to obtain mold bricks; d, curing, wherein the mold bricks obtained from step c are cured for 2-3 days under natural conditions to obtain finished products. Moisture in bricks can be evaporated quickly by means of heat generated from oxidization of iron powder, brick curing time is shortened, and the recovery cycle of solid waste or dangerous waste is shortened; meanwhile, soil in the solid waste or dangerous waste materials is used as an adhesive, so that solid waste or dangerous waste recovery cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of recovery and treatment of solid waste or hazardous waste, and in particular relates to a brick-making process for recovery and treatment of solid waste or hazardous waste. Background technique [0002] Usually, the recovery and treatment process of solid metal waste or hazardous waste is to first add a certain amount of reducing agent (such as carbon powder, etc.) and binder (such as cement, etc.) to the materials to be processed, and process them into bricks or balls. Then the bricks or pellets are sent to the smelting furnace for smelting, and the reducing agent is used to react with the metal oxides in the solid waste or hazardous waste to extract the solid waste or hazardous waste. Metal. [0003] The disadvantages of the existing brick-making process are: (1) A certain amount of water needs to be added during the brick-making process. Before putting the bricks into the smelting furnace for refining,...
