Problems solved by technology

After the zinc vapor is distilled, the agglomerated ore residue balls containing a certain amount of carbon in the distillation furnace are now treated as waste by all zinc smelters and have not been utilized.
In addition, the tar waste produced by the gas generator in the zinc smelting plant is piled up like a mountain and cannot be used, seriously polluting the environment

Embodiment Construction

[0006] The invention utilizes zinc smelting waste to produce a fuel that can replace raw coal, and the content ratio of the fuel is: 100 kg of residue balls, 100 kg of tar, and 50 kg of calcium oxide. The method of producing the fuel is to heat the tar to 90-120°C, add a certain amount of calcium oxide in proportion, stir well at 90-120°C and cool to normal temperature to obtain a block mixture; take a certain amount of block mixture Then add a certain amount of residue balls in proportion, mix them at room temperature, crush them into a plane shape and stir evenly to obtain a fuel that can replace raw coal. The residue ball mentioned above is a lump ore residue ball containing a certain amount of carbon in the distillation furnace after the zinc vapor is distilled; after testing, 30% of the carbon in the residue ball has not been burned, but the residue ball cannot be reused in the zinc smelting plant , can only be disposed of as waste. The tar mentioned above is the tar pro...

Abstract

A process for preparing the fuel instead of crude coal from the residual dregs generated during smelting zinc includes heating tar oil to 90-120 deg.C, proportionally mixing it with calcium oxide, stirring, cooling, proportionally adding said spherical residual dregs, stirring and puvlerizing.

Description

1. Technical field [0001] The invention relates to a fuel and a production method, in particular to utilizing zinc smelting waste to produce a fuel and a method capable of replacing raw coal. 2. Background technology [0002] In the process of zinc smelting in vertical tanks by fire method, clean coal, zinc-containing materials, pulp binders, and mixtures are mixed in a certain proportion, and then passed through rod milling, rolling, compacting, and agglomeration to make qualified products. Raw agglomerates, the agglomerates are coked and put into the distillation furnace under high temperature conditions, and the distilled zinc vapor is condensed and cast into ingots to obtain products. After the zinc steam is distilled out, the lump ore residue balls containing a certain amount of carbon in the distillation furnace are all treated as waste materials in all zinc smelting plants now, and are not utilized. In addition, the tar waste produced by the gas generator in the zinc...
