[0013] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be further described in detail. It should be understood that the described embodiments are only part of the embodiments of the present application, not all embodiments. The specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0014] The present application provides a technical solution: a traditional Chinese medicine residue resource utilization process, characterized by comprising the following steps: S1, collecting the traditional Chinese medicine residue and then classifying and storing, and then chopping and drying, evaporating the water in the traditional Chinese medicine residue, and completing the pretreatment of the traditional Chinese medicine residue; The chopping of the traditional Chinese medicine residue is performed by using a chopper, and the particle size of the chopped traditional Chinese medicine residue is less than 2mm. The drying treatment is performed using a chain dryer, which is a full-closed 3-layer reciprocating structure. The chain dryer can prolong the residence time of the traditional Chinese medicine residues with high water content in the chain dryer, improve the drying efficiency, and prolong the residence time of the traditional Chinese medicine residues with high water content in the chain dryer to 16 minutes during normal operation.

[0015] During the drying process, chemical substances such as nitric acid are generated due to the chemical gas contained in the boiler flue gas, and a large amount of water vapor is also generated during the drying of the traditional Chinese medicine residues. This is easy to cause corrosion of the dryer. Therefore, the chain dryer framework is made of stainless steel, and the inner wall is integrally packaged with a stainless steel plate. On the one hand, the corrosion resistance is ensured, and on the other hand, the overall weight is also reduced as much as possible.

[0016] In addition, a layer of thickened heat preservation type color steel plate is integrally installed on the outer side of the stainless steel inner wall of the chain dryer as a heat preservation material. This can reduce the heat loss of the dryer, facilitate disassembly and replacement, and facilitate maintenance and maintenance during later use.

[0017] S2, the pretreated traditional Chinese medicine residues are subjected to biomass gasification treatment by using a biomass gasification treatment method; The biomass gasification treatment is performed in a gasification furnace, and the generated combustible gas is hydrogen, carbon monoxide and methane; S3, the combustible gas generated during the biomass gasification treatment is completely combusted by a gas generator to generate heat and electric energy. The temperature and oxygen content and other parameters during the gasification and combustion processes are controlled during the power generation process to ensure that the expected power generation effect can be achieved and the pollution to the environment is reduced as much as possible. At the same time, it can adapt to the physical and chemical properties of the traditional Chinese medicine residues, and improve the efficiency and reliability of the biomass power generation; S4, the residues after the biomass gasification treatment are subjected to carbonization treatment to achieve the effect of biomass carbon.

[0018] The carbonization treatment is a secondary treatment of the residues by a biomass carbon furnace, which includes three stages of evaporation and water reduction, high-temperature decomposition and carbonization reaction.

[0019] The evaporation and water reduction stage is an evaporation treatment of the residues by increasing the temperature in a closed environment. The high-temperature decomposition stage is a decomposition of the organic matter in the residues to form fuel gas and solid carbon. The carbonization reaction stage is a conversion of the generated solid carbon into high-carbon by further heating.

[0020] In this embodiment, the traditional Chinese medicine residues are subjected to shredding and drying pretreatment until the water content of the traditional Chinese medicine residues is reduced to below 10%. Then, the traditional Chinese medicine residues are subjected to biomass gasification treatment to generate combustible mixed gas containing hydrogen, carbon monoxide and methane. The gas can form a new energy source as a boiler production power, realize zero waste discharge of production waste, reduce pollution to the environment, and achieve resource recycling and economic practicability.
