Abstract
The invention discloses a method of producing zinc chloride and aluminum chloride by using waste zinc-aluminum alloy. The objective of the invention is to provide the method of producing zinc chloride and aluminum chloride by using waste zinc-aluminum alloy. The method comprises the following steps: A, fragmentation, which is realized by mechanically fragmentating large waste zinc-aluminum alloy blocks into small blocks or fragments and putting the small blocks or fragments into an enclosed container; B, chlorination, which is realized by allowing chlorine to enter into the enclosed container in step A and subjecting chlorine and waste zinc-aluminum alloy in the enclosed container to a chemical reaction; C, condensation and sublimation, wherein, sublimated aluminum chloride is collected through a condenser and then is packaged; D, removal of chlorine, which is realized by blowing out chlorine in the enclosed container with air and absorbing chlorine-containing tail gas with alkaline water; E, collection of zinc chloride, wherein, iron-containing zinc chloride in the enclosed container is dried and packaged after iron is removed. The method provided in the invention is mainly used for extraction of zinc chloride and aluminum chloride from waste zinc-aluminum alloy, thereby achieving the purposes of changing waste into valuables and posing no pollution to environment.

Technical field
The present invention relates to a kind of method of producing zinc chloride and aluminum chloride, relate in particular to a kind of method of utilizing useless aluminium zinc production zinc chloride and aluminum chloride.
Background technology
Along with the develop rapidly of industry, the renewal of a large amount of industry, aviation, building materials has produced a large amount of aluminium zinc waste materials, is sought after a kind of technology and handles this waste material, turns waste into wealth and purpose free from environmental pollution to reach.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing useless aluminium zinc production zinc chloride and aluminum chloride, to overcome above-mentioned shortcoming.
For realizing above-mentioned purpose, technical solution of the present invention is: a kind of method of utilizing useless aluminium zinc production zinc chloride and aluminum chloride is characterized in that following steps:
A, fragmentation become the useless aluminium zinc of bulk in fritter or fragment and the encloses container of packing into through Mechanical Crushing;
B, chlorination feed chlorine in the encloses container of steps A, make chlorine and useless aluminium zinc generation chemical reaction wherein;
C, condensation distillation are collected the back packing with the aluminum chloride that distillation is come out through condensing surface;
D, drive chlorine, blowing air blows off the chlorine in the encloses container, absorbs chloride tail gas with buck;
E, collection zinc chloride are packed the iron content zinc chloride deironing after drying in the sealed vessel.
The invention has the beneficial effects as follows: through series of steps such as chlorination, distillation, condensation, deironing, can from useless aluminium zinc, extract aluminum chloride and zinc chloride respectively, reaching turns waste into wealth and purpose free from environmental pollution.

3), the water-soluble rear oxidation deironing of chlorine Hua Xinjing, drying in the reaction kettle, through chemical examination, the grade of aluminum chloride is 99.42%, zinc content＜0.1%, and the zinc chloride grade is 99.15%, and wherein Al, Fe content are all＜0.1%.
Instance 2
Scoriform aluminium zinc (containing zinc 23.50%, the aluminium 55.40%) 100kg that gives up is crushed to granularity less than 5cm, and the grade that obtains aluminum chloride is 99.48%, and the zinc chloride grade is 99.64%, foreign matter content all＜0.1%, all the other are with instance 1.
Instance 3
Scoriform aluminium zinc (containing zinc 7.3%, the aluminium 60.40%) 100kg that gives up is crushed to granularity less than 1cm, and the grade that obtains aluminum chloride is 99.65%, and the zinc chloride grade is 98.94%, foreign matter content all＜0.1%, all the other are with instance 1.
Above-mentioned foreign matter content is meant zinc content and the Al in the zinc chloride, the Fe content in the aluminum chloride, is weight percentage.
