Production equipment and preparation method of carbon composite

The invention relates to production equipment and a preparation method of a carbon composite. The production equipment comprises a pulverizer, a plant ingredient decomposition and enrichment device, an anaerobic fermentation device and a gas-fired boiler which are sequentially connected, wherein the plant ingredient decomposition and enrichment device is also sequentially connected with a first drying machine, a grinding machine, impregnating equipment, a filtering device, a second drying machine, a carbon material generator, a gas-solid separator and a bag type filter, the gas-solid separator and the bag type filter are respectively connected with a pressing machine, and the pressing machine is also sequentially connected with a rotary kiln, washing equipment and a third drying machine. The preparation method mainly comprises the following steps: pulverizing straws, carrying out solid-liquid separation, soaking with zinc chloride, activating, blending with an abandoned agricultural film, pressing into strips, and calcining. The production equipment and preparation method which are provided by the invention have the advantages that waste resources and energy sources are fully utilized, preparation cost is reduced, and adsorption performance of the carbon material is improved.
