The invention discloses a pyrolysis recovery device and working method utilizing waste heat of a fuel cell. The pyrolysis recovery device includes a pyrolysis furnace, a fuel cell arranged inside the pyrolysis furnace, a first gas supply system for delivering hydrogen to the fuel cell, and a second gas supply system for delivering air to the fuel cell , a third gas supply system for providing an oxygen-free environment for the pyrolysis furnace, a first recovery system for recovering pyrolysis gas of the pyrolysis furnace, and a second recovery system for recovering pyrolysis liquid of the pyrolysis furnace. The invention utilizes the waste heat generated by the fuel cell during operation to provide heat for pyrolysis. Solids, liquids and gases after pyrolysis can be recovered. The invention effectively utilizes the waste heat of the solid oxide fuel cell, improves energy utilization rate, and realizes full recycling of waste printed circuit boards.
Description
technical field [0001] The invention relates to the field of fuel cells, in particular to a pyrolysis recovery device and working method utilizing waste heat of fuel cells. Background technique [0002] Economic development and technological progress have accelerated the updating of electronic equipment, but at the same time, it has brought about the growth of electronic waste. Discarded printed circuit boards are a typical part of e-waste, and their increasing production has made the problem of e-waste increasingly serious. How to solve the problem of recycling waste printed circuit boards has attracted more and more attention. [0003] E-waste is both resourceful and harmful. From the perspective of resources, it is rich in recyclable useful materials such as metals, organic matter, and glass fibers. From the perspective of hazards, it contains some harmful substances, such as cadmium, mercury, chromium, polyvinyl chloride plastic, brominated resistors Combustion agents...
