Problems solved by technology

[0002] At present, the technology of using superheated steam as a heat carrier for carbonization has been widely studied, and its carbonization effect has also been recognized, but it has not been widely used in industrialization.
The main reason is that this technology has the shortcomings of low thermal efficiency, waste of water resources, and high cost of sewage treatment.
Looking at the existing superheated steam carbonization technology, heat is provided by superheated steam as a thermal fluid, which has strict requirements on equipment, high energy consumption for steam generation, large boiler footprint, high heat loss, large water resource consumption, and waste water. Due to the influence of conditions such as large emissions, the production cost is too high, the economy is poor, and t

Abstract

The invention provides a carbonization method implemented through gas cyclic heating. The method comprises the following steps: 1, introducing overheated water vapor into a carbonization device filled with materials to be carbonized, and getting the overheated water vapor involved into a carbonization reaction of the materials; 2, guiding gas in the carbonization device into heating equipment for reheating; 3, re-injecting the heated gas into the carbonization device for carbonization; 4, cyclically conducting step 2 and step 3 till the materials are sufficiently carbonized; 5, outputting and treating gas obtained after a reaction. The method has the advantages that heating efficiency is high, equipment operation cost is low, water resource consumption is little, pollution water treatment cost is low, the pressure and temperature are adjustable, no dioxin is generated in the treatment process, collected combustible gas is high in ratio, and a heated object can generate activated carbon high in specific surface area.
