Abstract

The invention discloses a smelting device and a smelting method for electronic scraps. The smelting device comprises a furnace body, a furnace top, a secondary combustion chamber and a spray gun, wherein a furnace hearth is defined in the furnace body; the furnace hearth is provided with an upper-end opening, and comprises a reaction region and a gas-phase region; a discharge hole is formed in the furnace body; the furnace top is connected with the furnace body and covers a part of the upper-end opening of the furnace hearth; a charge hole, a spray gun hole and a primary burner nozzle hole are formed in the furnace top; a secondary combustion chamber is defined in the secondary combustion chamber; a secondary burner nozzle hole is formed in the secondary combustion chamber; the secondary combustion chamber covers the other part of the upper-end opening, and the secondary combustion cavity communicates with the furnace hearth; a flue is arranged on the secondary combustion chamber, and the secondary combustion chamber is positioned at one side of a center line of the furnace hearth; and the spray gun is arranged in the spray gun hole in a penetrating mode, and the lower end of the spray gun extends into the reaction region. According to the embodiment of the invention, the smelting device for the electronic scraps can save fuels, improves smelting efficiency, and reduces emission of harmful gases.

Description

technical field [0001] The invention relates to the technical fields of non-ferrous metal smelting, hazardous waste treatment and resource recycling, in particular to an electronic waste smelting device and an electronic waste smelting method. Background technique [0002] Among the related technologies, the resource recycling technologies of discarded printed circuit boards, deflection coils, electronic components and other electronic waste in China are divided into two categories: one is physical technology such as dismantling, crushing, and sorting based on physical methods; Chemical techniques such as incineration, smelting, and acid dissolution are mainly chemical methods. Both of the existing methods have defects, for example, the physical method has limited opening of organic matter, the chemical method has low level of equipment, generally backward technology, and serious environmental pollution. [0003] With the needs of resources, environment and sustainable deve...
