Safety environment-friendly fuel and preparation technology thereof

Abstract

The invention relates to safety environment-friendly fuel and preparation technology thereof. The safety environment-friendly fuel comprises the following components in percentage by weight: 50-65 percent of waste coke powder, 10-20 percent of fly ash, 5-10 percent of anthracite, 2-5 percent of slag, 2-5 percent of high-heating-value waste slag, 5-9 percent of compounded curing agent and 10-14 percent of water. The preparation technology comprises the following steps: mixing the waste coke powder and the slag which are respectively ground and milled; adding the fly ash, the anthracite, the high-heating-value waste slag and the compounded curing agent and evenly mixing; and then adding the water and aging for 3-4 hours; and finally, forming the mixed material on a forming machine. The high-quality safety environment-friendly fuel is mainly prepared from low-cost byproducts of waste coke powder and fly ash by adding other combustible waste materials and the compounded curing agent and can replace the common coal product. The invention solves the problems of recycling utilization of waste materials and the problem of environment pollution caused by sulfur dioxide and carbon monoxide generated in the burning process of traditional coal products.

Description

technical field [0001] The invention relates to a fuel and a preparation process thereof, in particular to a safe and environment-friendly fuel and a preparation process thereof. Background technique [0002] Coal occupies a relatively important position in industry and people's daily life, especially with the soaring price of crude oil and natural gas, the share of coal in the fuel structure shows an increasing trend. Briquette is an energy-saving and environment-friendly coal-fired product. Traditional briquette occupies a more important position in industry and people's daily life. Especially with the soaring prices of crude oil and natural gas, the share of coal in the fuel structure has increased. In some areas, coal briquettes are even out of stock. However, traditional briquettes have disadvantages such as low combustion efficiency, large environmental pollution, and poor safety performance. Statistics show that more than 90% of the sulfur dioxide and soot in the na...

Problems solved by technology

[0004] The invention aims at the disadvantages of low combustion efficiency, dust pollution and poor safety performance in the traditional civil briquettes in the prior art. At the same time, the two waste resources of fly ash and coke powder, as well as enterprises such as chemical industry, light industry and papermaking, discharge a large amount of energy every year. The utilization rate of combustible waste is low, and the air and water environment are polluted, and a safe and environmentally friendly fuel and its preparation process are provided

[0006] The beneficial effects of the present invention are: aiming at the characteristics of waste coke powder and fly ash, two low-value by-products are used as main raw materials, and other combustible wastes and composite curing agents are added to make high-quality, safe and environment-friendly fuel to replace ordinary briquette products , which not only solves the problem of resource utilization of waste, but also solves the pollution problem of sulfur dioxide and carbon monoxide produced in the combustion process of traditional briquette products. At the same time, by adding a small amount of composite curing agent, the residue after product combustion has good gelling properties , which can ensure the cold and hot strength of the product, and can reduce the generation of dust.
