Embodiment Construction
[0033] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, on the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0034] like figure 1 A resource recovery processing method for waste circuit boards shown includes the following steps:
[0035] (1) Crushing the entire waste circuit board into small pieces with a diameter of 0.5 to 1mm through a crusher;
[0036] (2) The fragmented circuit board obtained in step (1) is mixed together with additives by a mixer, and the additives include calcium carbonate and calcium oxide, wherein the mass ratio of the additive to the circuit board is 1.3;
[0037] (3) Add the mixture of step (2) into the pyrolysis furnace, and perform anaerobic pyrolysis treatment at a temperature of 600° C. to obtain pyrolysis solid products and pyro...
