Embodiment Construction

[0018] As shown in Figure 1, the processing system described in this embodiment is composed of electrode melting furnace I, rotary retort II, decomposition combustion tower III, cooling tower IV, exhaust gas treatment tower V, and bag filter VI connected through pipelines.

[0019] Described electrode smelting furnace 1 is vertically provided with graphite upper electrode 3 and graphite lower electrode 4 on the same longitudinal axis in the middle of the furnace hall, the upper electrode can move up and down, the power supply mode of graphite electrode is DC or AC, and the working voltage is at 40 ~70 volts. A slag outlet 5 is provided at the bottom of one side of the furnace, and a copper outlet 6 is provided at the bottom of the other side of the furnace.

[0020] The rotary retort II has a hollow cylindrical barrel 2-1, which is supported by two supporting rollers 2-2 at the front and rear, and a ring gear 2-3 is welded on the barrel, and the ring gear is rotated by the gea...

Abstract

The invention relates to an innocent treatment system for copper powder containing organic matter and fiber glass and the treating process. Said system can not only recover valuable copper, but also can treat organic waste innocently. It is characterized by rational allocation, high purity of recovered copper powder, and thorough treatment of waste material and water gas. The innocent treatment system is characterized in that it is connected by electrode smelter, rotary retort, decomposition combustion tower, cooling tower, waste gas treating tower and jet cloth filter through conduit pipe. The invention can recover copper powder from waste wiring board, covering brass plate and other copper- containing rim leftover and can treat left waste material innocently.

Description

technical field [0001] The invention relates to a harmless treatment system and treatment process containing organic matter and glass fiber copper powder. It is suitable for recovering valuable copper powder from discarded circuit boards, copper-clad laminates and other copper-containing scraps and harmlessly disposing of the remaining waste. Background technique [0002] At present, the common method of discarding electronic circuit boards, copper-clad laminates and other copper-containing electronic wastes is: mechanically crush these wastes, and then use gravity separation and electrostatic separation technology to separate the metals and non-metals in them, and the recycled copper The powder is inevitably mixed with 5-20% non-metallic substances, such as resin and glass fiber in circuit boards, plastics and rubber in wires and cables. Direct smelting of this copper powder will produce volatiles that are very harmful to the human body, such as dioxin furans, bromobenzene...
