Problems solved by technology

[0008] The purpose of the present invention is to provide a multi-component renewable fuel based on household garbage and its preparation method in view of the low utilization rate of urban household garbage as a resource and the treatment of industrial and agricultural solid waste. The recycled fuel is based on household garbage Combustible components waste paper, textiles and a small amount of plastic are used as the main raw material components, and coal liquefaction residue with high calorific value and high viscosity and agricultural solid waste with a large output are used as combustion aids and binders to effectively realize urban domestic waste and industrial and agricultural waste. Resource Utilization of Solid Waste

Embodiment Construction

[0062] The present invention will be further described below in conjunction with the examples. The ingredients and relevant preparation process parameters of each implementation case are shown in the table below.

[0063] Table 1 Components and related preparation process parameters of each implementation case

[0064]

[0065] see Figure 1 to Figure 10 Shown, the preparation steps of embodiment 1 are as follows:

[0066] (1) Separating municipal solid waste into long strips of plastics and textiles through two-stage trommel bag breaking and hanging, and then separating plastics, waste paper and For textile fragments, the double air chamber multi-functional air separator separates plastics, waste paper and textile fragments, and after further air separation, the combustible components of domestic waste composed of waste paper and textiles are separated;

[0067] (2) Drying the combustible components of household waste at a temperature of 200°C so that the moisture conte...

Abstract

The invention discloses a multi-component regenerated fuel based on domestic garbage and a preparation method thereof, which are suitable for resource processing of solid wastes. The regenerated fuel is formed by mixing combustible components in the domestic garbage, coal liquefaction residues, agricultural solid wastes and calcium oxide in proportion, and specifically comprises the following components in percentage by mass: 62.5%-77.0% of the combustible components in the domestic garbage, 10.0%-20.0% of the coal liquefaction residues, 5.0%-14.0% of the agricultural solid wastes and 4.5%-7.5% of the calcium oxide. The preparation method comprises the following steps: firstly separating the combustible components from the domestic garbage; then performing drying, crushing and other pretreatment on the combustible components in the domestic garbage, the coal liquefaction residues and the agricultural solid wastes; further mixing all the components according to the ratio, and uniformlystirring; and finally shaping. The regenerated fuel has the advantages of higher calorific value, stable combustion and low secondary pollution, and can realize resource utilization of the urban domestic garbage and the industrial and the agricultural solid wastes.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and energy, in particular to a multi-component regenerative fuel based on domestic garbage and a preparation method thereof, which is suitable for resource treatment of solid waste. technical background [0002] The annual output of municipal solid waste in my country is nearly 150 million tons, and it is increasing at an annual rate of 8%. According to incomplete statistics, the total stockpile of urban domestic waste in my country has reached more than 6 billion tons, and about two-thirds of the cities have fallen into the predicament of garbage siege. It is an urgent requirement from many aspects such as environment, economy and society to deal with municipal solid waste to make it reduce, harmless and recycle. [0003] Municipal solid waste is a complex mixture of various substances, consisting of dust, masonry, waste paper, waste plastic, waste textiles, metal, kitchen wast...
