Problems solved by technology

[0007] The purpose of the present invention is to provide a molding fuel mixed with combustible components of garbage and coal liquefaction residue and its preparation method in view of the serious waste of recyclable heat energy in the current municipal solid waste and the problem of by-product treatment caused by coal liquefaction technology. The briquette fuel uses the combustible components of domestic waste, waste paper and textiles, as the main raw material components, and uses high-calorific value, high-viscosity coal liquefaction residue as the combustion aid and binder, while realizing the reduction and harmlessness of domestic waste. Realized the resource utilization of household garbage and coal liquefaction residue

Embodiment 1

[0063] see Figure 1 to Figure 10 As shown, in this embodiment, the composition and weight percentage of the briquette fuel mixed with the combustible components of the garbage and the coal liquefaction residue are: 62.0% of the combustible components of household garbage, 28.0% of the coal liquefaction residue, and 10.0% of calcium hydroxide. Proceed as follows:

[0064] (1) The municipal solid waste is separated into long strips of plastic and textiles through the broken bags and picking and hanging of the two-stage drum screen, and then the plastic, waste paper and Textile scraps, the double-chamber multi-function wind separator separates plastic, waste paper and textile scraps and separates the combustible components of household waste composed of waste paper and textiles after further wind separation;

[0065] (2) Dry the combustible components of household waste at a temperature of 200°C to reduce the moisture content to 20%;

[0066] (3) Use shear crusher to crush com...

Embodiment 2

[0078] In this embodiment, the composition and mass percentage of the briquette fuel are: 70.0% of the combustible components of household waste, 21.0% of coal liquefaction residue, and 9.0% of calcium hydroxide. The drying temperature in the preparation step (2) was 230° C., the preparation step (3) was stored for 20 minutes, and other steps were the same as those in Example 1.

Embodiment 3

[0080] In this embodiment, the composition and mass percentage of the briquette fuel are: 70.0% of the combustible components of household garbage, 21.0% of coal liquefaction residue, and 9.0% of magnesium hydroxide. The drying temperature in the preparation step (2) was 230° C., the preparation step (3) was stored for 20 minutes, and other steps were the same as those in Example 1.

Abstract

The invention discloses a formed fuel mixed with combustible components in garbage and coal liquefaction residual and a preparation method, which are applicable to resource recycling of domestic garbage and coal liquefaction residual. The formed fuel is mixed by the following components in percent by weight: 62.0%-80.0% of combustible components in domestic garbage, 12.0%-28.0% of coal liquefaction residual and 8.0%-10.0% of desulfurizing agent. The preparation method comprises the following steps of: firstly sorting combustible components in the domestic garbage, and then drying and crushing the combustible components in the domestic garbage; then mixing the combustible components in the domestic garbage, the coal liquefaction residual and the desulfurizing agent according to the matching ratio, stirring uniformly; and finally forming. The formed fuel disclosed by the invention has the advantages that the heat value is high, the secondary pollution is low, the mechanical performance is excellent, the reduction and the harmlessness of the domestic garbage are realized, and meanwhile, the recycling of the domestic garbage and the coal liquefaction residual is realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection energy, in particular to a molding fuel mixed with combustible components of garbage and coal liquefaction residue and a preparation method thereof, which is suitable for resource treatment of domestic garbage and coal liquefaction residue. 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...
