Method used for preparing environment-friendly solid fuel from industrial waste material

Abstract

The invention discloses a method used for preparing environment-friendly solid fuel from industrial waste material. The method comprises following steps: 1, industrial waste material is subjected to dehydration, drying, and crushing to remove heavy metal, a microbe bacteriostatic agent solution is added for uniform stirring mixing; 2, an combustion improver is added into an obtained mixed solution, wherein the combustion improver comprises active carbon, copper nitrate, methyl formate, methanol, potassium perchlorate, calcium nitrate, nanometer magnesium oxide powder, and a liquid combustion improver obtained through mixing of amyl nitrite and distilled water; 3, an obtained mixed slurry is subjected to solid-liquid separation to obtain solid combustion aid and waste liquid, and the wasteliquid is discharged; 4, the solid combustion aid is subjected to grinding, ferrocene and a biomass adsorbent are added, an obtained mixed product is introduced into a fermentation tank, magnesium sulfate and active cellulase are added, an acidic liquid is added to adjust the pH value to 5.1 to 6.2 for fermentation; and 5, an obtained fermentation broth is subjected to air drying, crushing, and extruding successively so as to obtain the solid fuel. According to the method, recycling of industrial waste material is realized, and industrial by-product zero discharge is realized.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of resources, in particular to a method for preparing environmentally friendly solid fuel from industrial waste. Background technique [0002] With the development of society, the industrial organic waste produced by industrial production is also increasing day by day, mainly organic solid waste industrial waste produced by clothing, shoemaking, leather, textile, clothing, leather goods, packaging, plastic products, etc. They contain high levels of organic matter and certain heavy metals, etc. The traditional ways of disposing of waste mainly include landfill and incineration, but these two methods will cause secondary pollution to the environment, and it is difficult to meet environmental protection requirements. [0003] At present, there are methods of processing into uniform and easy-to-completely combustible particle-derived fuels, but this type of organic industrial waste h...

Problems solved by technology

[0002] With the development of society, the industrial organic waste produced by industrial production is also increasing day by day, mainly organic solid waste industrial waste produced by clothing, shoemaking, leather, textile, clothing, leather goods, packaging, plastic products, etc. They contain high organic matter and certain heavy metals, etc. The traditional ways of disposing of waste mainly include landfill and incineration, but these two methods will cause secondary pollution to the environment, and it is difficult to meet environmental protection requirements

[0003] At present, there are methods of processing into uniform and easy-to-completely combustible particle-derived fuels, but this type of organic industrial waste has poor adhesion and is difficult to form, which is not conducive to subsequent use; and the organic matter contains certain acidic substances and sulfur content. Pollution is easily generated during processing, and it is difficult to meet environmental protection requirements

[0004] The invention application with Chinese application number CN201310580802.X discloses a production method for preparing fuel oil from oil field waste, which mainly solves the problem of environmental pollution caused by oil field waste and by-products produced by chemical enterprises. The invention application with Chinese application number CN201210412343.X Disclosed is a biomass particle fuel produced by using tobacco leaf waste and its preparation method, which mainly solves the problem of environmental pollution caused by the incineration of tobacco leaf waste. The invention application with the Chinese application number CN201310656100. The method of producing biomass fuel from mushroom culture medium waste mainly solves the problem that a large amount of culture medium waste will pollute the environment during the cultivation of shimeji mushrooms. None of the above patents makes reasonable use of the carbon in the waste, resulting in a waste of energy At the same time, the process of converting waste materials into dyes produces gases that pollute the environment, increasing air pollution
