Cooperative heat supply system for pyrolysis of waste circuit board and heat treatment method of waste circuit board

The invention belongs to the technical field of waste circuit board pyrolysis treatment, and particularly relates to a collaborative heat supply system for waste circuit board pyrolysis and a heat treatment method of a waste circuit board. The collaborative heat supply system for waste circuit board pyrolysis comprises an outer heat supply system and an inner heat supply system. The external heat supply system comprises a furnace body smoke jacket (20) and a combustion chamber (30), and a pyrolysis gas pipeline (40) of the pyrolysis furnace body (10) is communicated with the combustion chamber (30); the internal heat supply system comprises a superheated steam generator (50), and the furnace body clamping sleeve smoke outlet (22) is communicated with the superheated steam generator (50) so that high-temperature smoke passing through the furnace body smoke clamping sleeve (20) can provide a heat source for the superheated steam generator (50). Through cooperation of the superheated steam and the high-temperatu
