Abstract

The invention discloses a device and method for producing zinc powder by using alcohol-based fuel. The device comprises an alcohol-based fuel burning system, a zinc powder furnace, a smoke exhaustingsystem and a zinc powder collecting device, wherein the interior of the zinc powder furnace is divided into a melting evaporation tank and a burning chamber by a flame separation plate which is transversely arranged; one side of the melting evaporation tank is connected to the zinc powder collecting device; and one side of the burning chamber is connected to the alcohol-based fuel burning system,and the other side of the burning chamber is connected to the smoke exhausting system. According to the device, the alcohol-based fuel burning system is used for providing heat to a horizontal zinc powder furnace body; and after being heated, a zinc ingot of the zinc powder furnace body is melted and evaporated to enter the zinc powder collecting device, and then is cooled to form zinc powder. Thealcohol-based fuel burning system is connected to the zinc powder furnace, so that alcohol-based fuel is used for providing heat and is fully burned; and after the alcohol-based fuel is burned, carbon dioxide and water vapor are generated, gases polluting environments are not generated, and the disadvantages such as lots of waste residue and phenol-containing wastewater difficult to treat generated by using coal as a heat source are completely avoided.

Description

technical field [0001] The invention relates to a device and method for producing zinc powder, in particular to a device and method for producing zinc powder using alcohol-based fuel. Background technique [0002] Zinc is a metallic element with an atomic number of 30 and a density of 7.14 g / cm 3 , with a melting point of 419.5°C. A layer of dense zinc carbonate protective film is easy to form on the surface of zinc metal under normal temperature air atmosphere to prevent further oxidation of zinc, so zinc has excellent atmospheric corrosion resistance. The most widely used zinc powder is the galvanizing industry, which is mainly used for the surface coating of various steel materials. [0003] At present, the furnace types used in the industrial production of zinc powder by the distillation condensation method mainly include horizontal furnaces and tower furnaces, among which the horizontal furnace is the most widely used furnace type, and its production process is to hea...
