Abstract

The invention relates to an extraction device, in particular to an extraction device for arsenic in copper smelting waste residues. The technical problem to be solved is to provide an extraction device for arsenic in copper smelting waste slag, which can crush the waste slag so as to improve the extraction effect. According to the technical scheme, the extraction device for arsenic in the copper smelting waste residues comprises a containing box, a hot melting furnace, a material distribution box, a gas outlet frame, a material passing frame, a gas barreling mechanism and an explosion mechanism, the hot melting furnace is arranged on the upper side of the interior of the containing box, the material distribution box is arranged on the upper side of the containing box, a rotary disc is rotationally connected to the middle of the front side of the material distribution box, and the gas outlet frame is arranged on the left side of the material distribution box; a material passing frame is arranged between the upper portions of the front side and the rear side of the material distributing box, the front side and the rear side of the upper portion of the air outlet frame are each provided with two air barrel filling mechanisms in a threaded mode, and an explosion mechanism is arranged in the material passing frame. According to the arsenic extraction device, large-size waste residues can be extruded through the exploder, so that the crushed waste residues are smelted more easily, and the arsenic extraction effect is improved.

Description

technical field [0001] The invention relates to an extraction device, in particular to an extraction device for arsenic in copper smelting waste residue. Background technique [0002] In the process of industrial copper smelting, waste residues mainly composed of arsenic sulfide (As2S3) will be produced. The arsenic index in these waste residues exceeds the standard. If these waste residues are directly discharged without processing, they will easily cause water pollution, soil pollution and air pollution. Environmental problems such as pollution do not conform to the concept of sustainable development. Therefore, it is necessary to use some extraction devices for arsenic in copper smelting waste residues to solve this problem. [0003] The extraction of arsenic sulfide waste residue in China can be achieved by high-temperature oxidative roasting. Arsenic sulfide reacts with oxygen at high temperature to obtain the products arsenic trioxide (As2O3) and sulfur dioxide (SO2), ...
