Method and device for preparing carbon material by heating molten salt and pyrolyzing biomass through solar energy

Abstract

The invention provides a method and a device for preparing a carbon material by heating molten salt and pyrolyzing biomass through solar energy, relates to the technical field of preparing the carbon material through the biomass, and aims to solve the problems that the technology for preparing the carbon through the molten salt cannot continuously prepare the carbon, the energy consumption is relatively high, and the mass production is difficult to realize. And the carbon production quality is ensured, the carbon production time is shortened, and the carbon production efficiency is improved. In the pretreatment of the biomass, high-temperature hot gas obtained in the pyrolysis reaction is used for ensuring a drying system, so that waste gas resources are fully utilized, and meanwhile, the pipeline safety and the pyrolysis efficiency are also ensured. In the separation operation, a plurality of layers of filter screens and a push plate are utilized to separate the reacted fused salt from the prepared biomass charcoal, so that the physical properties of the fused salt and the prepared biomass charcoal at high temperature are utilized to perform effective separation, the reaction of the biomass charcoal and the circulation of the fused salt are not interrupted, and continuous carbon preparation is really realized.

Description

technical field [0001] The invention relates to the technical field of biomass carbon materials, in particular to a method and a device for solar heating molten salt pyrolysis biomass carbon materials. Background technique [0002] Agriculture is the main source of waste generation, and it is also a difficulty in the utilization of waste resources. Biomass wastes produced in human production and life come directly or indirectly from agriculture. Common biomass wastes are mainly the residual biomass after the death, harvesting, processing and utilization of organisms. [0003] As a single element, carbon can form various substances with different structures and properties. With the changes of the times and the progress of science, people continue to discover and utilize carbon materials, so the development and application of carbon elements have infinite possibilities. Carbon is a widely used material and is in high demand in many industries. Porous carbon can store hydroge...
