Embodiment Construction

[0022] The invention can separate and purify the carbon-containing part from the solid residue of garbage pyrolysis, perform a series of process treatments on the carbon-containing part, prepare the activated carbon with adsorption function, and realize the maximum utilization of the solid residue of garbage pyrolysis.

[0023] Concrete technique of the present invention is as follows, can refer to simultaneously figure 1 :

[0024] 1) First, crush the cracked solid residue with rubber rollers (multiple sets of rubber rollers can be installed on the conveyor belt during industrialization), and the rubber rollers can crush the carbon powder without crushing sand or gravel. Glass slag and other materials to facilitate the next step of screening;

[0025] 2) The crushed material is screened with a multi-stage mechanical vibrating screen, and the screened undersize is reserved for later use. For each batch of different waste raw materials and different parameters of the cracking...

Abstract

The invention discloses a method for preparing active carbon with solid residues from microwave pyrolysis of urban solid domestic wastes. The method comprises the steps of: rolling the pyrolyzed solid residual material with a rubber roller, removing oil from the siftage screened out and conducting drying and water removing, then in order carrying out electric separation, flotation, acid and alkali treatment and washing, and finally activation, thus obtaining the active carbon. The method of the invention can dispose wastes, reduce pollution, and also can prepare active carbon and reutilize resources reasonably and fully. As a result, exploitation of primary resources can be reduced and a great deal of energy can be saved.

Description

technical field [0001] The invention relates to a treatment technology of urban solid domestic waste, specifically refers to a method for resource utilization of solid residue obtained by microwave cracking of urban solid domestic waste to finally prepare activated carbon, and belongs to the technical field of waste treatment and resource utilization. [0002] Background technique [0003] At present, most municipal wastes are incinerated for power generation and residues are landfilled to achieve comprehensive treatment. This method has multiple benefits such as waste volume reduction, harmlessness and resource utilization. However, after garbage incineration, a large amount of waste gas or poisonous gas will be produced, especially dioxin-like pollutants, which are recognized as first-class carcinogens, and a large amount of residue will be left to be landfilled and disposed of. [0004] The treatment of municipal solid domestic waste by microwave pyrolysis is a new type...
