Clean fuel prepared from traditional Chinese medicine residues

Abstract

The invention relates to a clean fuel prepared from traditional Chinese medicine residues, which comprises the following components in percentage by weight: 10-15 parts of coal gangue, 5-15 parts of jacobsite slag, 25-30 parts of industrial salt slurry, 1-5 parts of blast furnace slag, 30-40 parts of traditional Chinese medicine residue, 1-5 parts of combustion improver and 0.5-3 parts of synergist. The preparation process of the clean fuel comprises the following steps: baking the traditional Chinese medicine residues at high temperature to lower the water content to 1-4% below; and mixing and pulverizing the components, and finally, carrying out compression forming on the components by a forming machine. The clean fuel is simple in technique, provides a convenient environment-friendly treatment mode for traditional Chinese medicine residues discharged by the current enterprises, and converts the traditional Chinese medicine residues into energies, resources and harmless substances. After the traditional Chinese medicine residues and industrial solid waste are prepared into the clean fuel, the environmental pollution is reduced, and the economic value can be implemented.

Description

Technical field [0001] The invention relates to the technical field of waste treatment and clean energy, in particular to a new type of clean fuel prepared by using bulk industrial solid waste and traditional Chinese medicine residue. Background technique [0002] At present, China's industrial solid waste stockpiles reach 10 billion tons, and they continue to accumulate at a rate of 1 billion tons per year. The air and groundwater are all polluted in different ways. What's more serious is that during the storage of these industrial solid wastes, a large amount of heavy metal ions, such as lead, arsenic, mercury, cadmium, chromium, and cobalt, will enter the atmosphere, water, and soil, causing serious environmental pollution. Heavy metals in the human body can interact strongly with proteins and various enzymes, causing them to lose their activity. They may also be enriched in some organs of the human body. If they exceed the limit that the human body can tolerate, they will cau...

Problems solved by technology

Most of the composting process is natural and simple composting. Due to the long fermentation period, low degree of harmlessness and poor sanitary conditions, it is rarely used now; the use of traditional Chinese medicine dregs for edible fungus cultivation may inhibit the composting due to the complex composition of the dregs The growth of mycelium and the separation of medicinal residues are the bottleneck problems; when the medicinal residues are processed into feed additives, further in-depth and detailed research is needed on their medicinal functions and effects on animal growth and development

Due to the immaturity and limitations of the above utilization methods, none of them can be applied on a large scale. According to incomplete statistics, the dregs of traditional Chinese medicine disposed of by the above methods are only about 1% of the annual output, and there are still a huge amount of dregs of traditional Chinese medicine that cannot be processed. achieve effective disposal
