Embodiment 1

[0025] The ratio of renewable fuel is 30% of waste residue generated during the dismantling process of automobiles, 20% of oily sludge, 20% of waste paint residue, 10% of waste toner, 10% of waste resin, 9% of coking blocks, and 1% of desulfurization and dechlorination agent CaO . After mixing the above, stir evenly, place in a fuel sphere forming machine for compression molding, dry and consolidate to a moisture content of 14%, and obtain fuel spheres.

[0026] The calorific value of the fuel bulb was measured to be 4306kcal / kg, the sulfur fixation rate was 71.6%, and the chlorine fixation rate was 71.2%.

Embodiment 2

[0028] The ratio of renewable fuel is 40% of waste residue generated during the dismantling of automobiles, 25% of oily sludge, 15% of waste paint residue, 5% of waste toner, 5% of waste resin, 9.5% of coke, and desulfurization and dechlorination agent CaO0. 5%. The treatment method was the same as in Example 1, and fuel spheres with a water content of 10% were obtained.

[0029] The calorific value of the fuel bulb is 4257kcal / kg, the sulfur fixation rate is 69.4%, and the chlorine fixation rate is 70.4%.

Embodiment 3

[0031] The proportion of renewable fuel is 20% of waste residue generated during the dismantling process of automobiles, 15% of oily sludge, 30% of waste paint residue, 15% of waste toner, 10% of waste resin, 7% of coking blocks, and 3% of desulfurization and dechlorination agent CaO . The treatment method was the same as in Example 1, and fuel spheres with a water content of 5% were obtained.

[0032] The calorific value of the fuel bulb is 4681kcal / kg, the sulfur fixation rate is 80.3%, and the chlorine fixation rate is 81.1%.

Abstract

The invention discloses a generative fuel produced by using an industrial solid waste and a preparation method thereof. The method comprises the following steps: taking industrial solid wastes such as waste residues, oily sludge, waste paint slags, waste powdered ink, waste resin, coking blocks and the like generated in a car dismantling process as calorific value components; adding a desulfurization and dechlorination agent as an auxiliary component; evenly mixing, pressing and molding, and drying, so as to obtain the generative fuel. The heat value of the generative fuel disclosed by the invention is over 4,000kcal / kg, the generative fuel can be used as an alternative fuel for a cement plant and a power plant, and is good in inflammability, and free of any combustion improver; the burnt ash content is below 20%, the fire coal substitution rate can be up to 80%, the sulfur fixation efficiency is 69.4-80.3%, the chlorine fixation efficiency is 70.4-81.1%, the content of hazardous substances (based on S and Cl) in the combustion tail gas is reduced by 70-80%. The generative fuel and the preparation method thereof provided by the invention have outstanding environmental benefits.

Description

technical field [0001] The invention relates to the technical field of resource utilization of industrial solid waste and environmental protection energy, and in particular provides a recycling, harmless and reduction treatment method for refractory industrial solid waste. Background technique [0002] With the acceleration of my country's industrialization process, various domestic or foreign-funded chemical companies have sprung up, and more and more cities have established industrial parks. However, a severe environmental problem that follows is that the types and quantities of associated industrial solid wastes have increased significantly. Typical hazardous industrial wastes include waste paint slag, waste toner, waste resin, oily sludge, waste Organic paints, waste activated carbon and more. [0003] As hazardous solid waste, industrial solid waste has higher treatment standards and difficulties compared with domestic waste, and the operation is more complicated and t...
