The chemical property of zinc is active, and a layer of thin and compact basic zinc carbonate film is generated on the surface of the zinc in the air at normal temperature, so that the zinc can be prevented from being further oxidized; when the temperature reached 225 ℃, the zinc oxidized drastically. Zinc has excellent atmospheric corrosion resistance, and a protective film is easy to form on the surface of the zinc at normal temperature, so that the zinc has the greatest application in the zinc plating industry and is mainly used for surface plating (such as galvanized plates) of steel products and steel structural members. A large amount of galvanized slag is produced in the galvanization process, and the galvanized slag is difficult to be used as a raw material for smelting in a zinc smelting plant, so that the galvanized slag can be effectively utilized in recycling and protecting the environment, and waste and pollution are avoided.
The zinc powder preparation method by using the galvanized slag provided by the prior art needs a heating-condensing-changing-heating repeated circulation process every time the zinc powder is prepared, and continuous production cannot be performed; in addition, the method provided by the prior art usually scoops out the zinc liquid directly when separating the metal zinc liquid from the oxidizing slag, so that the zinc liquid and the oxidizing slag are not thoroughly separated, and zinc with higher purity can be prepared by vacuum distillation, so that the preparation process is complex and potential safety hazard is increased.

There is a need for an improvement over existing vacuum distillation furnaces to reduce the hazard of zinc fouling.
