Embodiment Construction

[0054] figure 1 A zinc dust production plant 10 is shown. The apparatus 10 includes a vertical crucible melting furnace 12 , a vertical crucible vaporizer 14 and a condenser 18 . Molten material delivery means in the form of refractory tanks and launders 20 are provided between the melting furnace 12 and the gasification furnace 14 . A vapor delivery means 22 in the form of a silicon carbide jumper is provided between the vaporizer 14 and the condenser 18 .

[0055] The melting furnace 12 includes a refractory lining 24 through which a gas burner 26 protrudes, the burner being located on the inner side of the refractory lining 24 . The refractory lining is mounted on a hydraulically driven inclined table 28 . Inside said furnace lining 24 is provided a silicon carbide melting crucible 30 having an open end exposed to free atmosphere. A burner compartment 32 is defined between the outer wall of the melting crucible 30 and the interior of the refractory lining 24 . An outfl...

Abstract

A method of production of Zinc dust, which includes melting Zinc products in a melting furnace on a semi-continuous basis, transferring at least a part of the molten Zinc products to a vaporizing furnace, vaporizing the molten Zinc in the vaporizing furnace into Zinc vapour on a substantially continuous basis, transferring Zinc vapour from the vaporizing furnace to a condenser, and condensing the Zinc vapour to form Zinc dust and cycling the Zinc vapour in the condenser and making the Zinc vapour pass through a cyclone type cooler. A Zinc dust production device includes a vertical crucible melting furnace (12), a vertical crucible vaporizing furnace (14), a condenser (18) in fluid flow communication with the vaporizing furnace for receiving Zinc vapour into the condenser, wherein the condenser is provided with a heat exchanger in the form of a vapour cycle system (58).

Description

[0001] The present invention relates to the production of zinc powder. Specifically, the present invention relates to a method of producing zinc powder and a zinc powder production equipment. Background technique [0002] The present inventors are aware of zinc processing using retort furnaces, but have found that existing retort furnaces require the production of zinc powder to be carried out in batches. Batch processing of raw materials leads to inefficiencies in the production process. The purpose of the present invention is to solve this inefficiency and reduce energy consumption. Contents of the invention [0003] A first aspect of the present invention provides a method of producing zinc powder, the method comprising: [0004] Semi-continuous melting of zinc products in a melting furnace; [0005] transferring at least a portion of the molten zinc product to a vaporizer; [0006] substantially continuously vaporizing molten zinc into zinc vapor in said vaporizer; ...
