Description

Rotary kiln with quantitative recovery function for zinc oxide production

Technical Field

The invention relates to the technical field of rotary kiln devices, in particular to a rotary kiln with a quantitative recovery function for zinc oxide production.

Background

The rotary kiln is a rotary calcining kiln (commonly called a rotary kiln), has a similar appearance to a rotary kiln, is also called a rotary kiln, and belongs to building material equipment. Rotary kilns can be classified into cement kilns, metallurgical chemical kilns and lime kilns according to the materials to be treated. The cement kiln is mainly used for calcining cement clinker, and is divided into two main types, namely cement kiln produced by dry method and cement kiln produced by wet method. The metallurgical chemical kiln is mainly used for magnetizing roasting of lean iron ores in iron and steel plants in metallurgical industry; oxidizing and roasting chromium and nickel iron ores; roasting high alumina bauxite ore in a refractory material factory, roasting clinker in an aluminum factory and aluminum hydroxide; roasting chromium ore sand, chromium ore powder and other minerals in chemical plants. Lime kilns (i.e., active lime kilns) are used to calcine active lime and light burned dolomite for iron and steel plants and ferroalloy plants.

When extracting zinc element in solid waste, there is the oxidation-reduction equipment that is used to carry out the extraction, and the purpose is to collect after carrying out oxidation-reduction reaction gasification to zinc element in it becomes secondary zinc oxide gas, calcine it through the rotary kiln, and zinc element in it forms secondary zinc oxide, in order to avoid the circumstances that causes extravagant and difficult recovery when throwing the material to the rotary kiln inside, designs a zinc oxide production and uses rotary kiln with quantitative recovery function.
