Embodiment 1

[0025] (1) Spray 2% microbial composite bacteria agent to the collected wet garbage, and the processed product is vibrated, crushed and sorted;

[0026] (2) Grinding the dry matter after the above treatment to a particle size ≤ 1.3mm under negative pressure (-0.6Pa) conditions, and performing solid-liquid separation;

[0027] (3) The liquid mixture obtained after the solid-liquid separation in step (2) is sent into a micron air-dissolving machine, and the oil and water mixed liquid are separated; 3‰ sulfa collector and 0.5‰ turpentine are added in the water mixed liquid The foaming agent is sent to the first-stage screw stacker, and the separation degree of solids in the liquid is improved through the principle of aeration and oxidation, and the first-grade solid product and the first-grade liquid product are separated; the first-grade liquid product is discharged after treatment, and the first-grade solid product is discharged. The product is separated by a secondary screw st...

Embodiment 2

[0029] (1) Spray 1% microbial composite bacterial agent to the collected wet garbage, and the processed product is vibrated, crushed and sorted;

[0030] (2) Grinding the dry matter after the above treatment to a particle size ≤ 1.3mm under negative pressure (-0.6Pa) conditions, and performing solid-liquid separation;

[0031] (3) The liquid mixture obtained after the solid-liquid separation in step (2) is sent into a micron air-dissolving machine to separate oil and water mixed liquid; add 1‰ sulfa collector and 0.5‰ turpentine to the water mixed liquid The foaming agent is sent to the first-stage screw stacker, and the separation degree of solids in the liquid is improved through the principle of aeration and oxidation, and the first-grade solid product and the first-grade liquid product are separated; the first-grade liquid product is discharged after treatment, and the first-grade solid product is discharged. The product is separated by a secondary screw stacker to obtain ...

Abstract

The invention relates to a method for preparing clean fuel by utilizing wet garbage. The method comprises the steps: carrying out microbiological treatment, carrying out negative-pressure solid-liquid separation, and respectively treating a liquid mixture and a solid mixture to obtain the clean fuel. The method further optimizes the subsequent process links of microbiological treatment, not only makes up the market blank of energy utilization of wet garbage, but also solves the problem of potential food safety hazards in preparation of organic fertilizers.

Description

technical field [0001] The invention belongs to the field of garbage treatment, in particular to a method for preparing clean fuel from wet garbage. Background technique [0002] At present, some cities in my country have begun to implement garbage classification. Since Chinese food is usually oily and salty, it is much more difficult to deal with wet garbage or kitchen waste than other types of garbage. At present, the mainstream domestic kitchen waste treatment processes mainly include: [0003] (1) Landfill disposal. Most of the kitchen waste in our country enters the landfill along with other domestic waste for disposal. The landfill site is empty, so the treatment capacity is large, and the operating cost is low, which makes it widely used. However, landfill needs to occupy a large amount of land, and the permeate of food waste will seriously pollute the surrounding soil and groundwater resources. [0004] (2) Incineration treatment. The incineration method has a h...
