1. A pyrolysis vapor outlet anti-coking device of adsorbing medium self-recycling regeneration, comprising a particle flow adsorbing system and a medium burning regeneration recycling system in mutual communication; wherein
the particle flow adsorbing system is configured to enable tar to be adsorbed on an outer surface of an adsorbing medium to form a coking layer, and convey a coking adsorbing medium into the medium burning regeneration recycling system;
the medium burning regeneration recycling system is configured to burn the coking layer on the outer surface of the adsorbing medium to realize regeneration of the adsorbing medium and convey the regenerated adsorbing medium into the particle flow adsorbing system for recycling use;
the particle flow adsorbing system comprises a pyrolysis vapor pipe, one end of the pyrolysis vapor pipe is provided with a pyrolysis vapor inlet and a medium recycling inlet, the other end of the pyrolysis vapor pipe is provided with a pyrolysis vapor outlet and a medium recycling outlet, and a blocking net is disposed between the pyrolysis vapor outlet and the medium recycling outlet in the pyrolysis vapor pipe; and
the medium burning regeneration recycling system comprises a fluidized burning furnace, a gas-solid separator and a first blower, the medium recycling outlet of the pyrolysis vapor pipe is connected with a medium inlet of the fluidized burning furnace, an outlet of the fluidized burning furnace is connected with an inlet of the gas-solid separator, a medium outlet of the gas-solid separator is connected with the medium recycling inlet of the pyrolysis vapor pipe, and an air outlet of the first blower is connected with the fluidized burning furnace.
