Example Embodiment
[0037] Example 1
[0038] Start the reaction device, burn the bio-oil, heat the heat carrier to reach the predetermined temperature (560 ° C), use rice husk powder as the raw material of biomass waste, and transport it to the reaction device through the feeding system. The feeding rate of biomass waste is 2.33t / h.
[0039] The biomass waste and the heat carrier are in direct contact with heat exchange during the downward process, the heat carrier and the biomass waste are fully mixed, and their heat is transferred to the biomass waste. The biomass waste is heated to above 500°C in an instant (1-2s), and the biomass waste undergoes a thermal cracking reaction, and most of the volatile matter and moisture of the biomass waste form thermal cracking vapor. Most of the ash and fixed carbon of biomass waste form biochar.
[0040] After the thermal cracking reaction, the heat carrier is separated and sent to the heater. One or more sets of cyclone separators are used to separate t...
