Abstract
Description
Technical Field
[0001] This utility model belongs to the field of inorganic powder production technology, and specifically relates to a humidification and static electricity removal device for inorganic powder production. Background Technology
[0002] Electrostatic adsorption and agglomeration negatively impact the production of inorganic powders. Eliminating this effect typically involves static discharge, temperature and humidity control, using electrostatic jumpers for atomized humidification of the inorganic powders, and constructing constant temperature and humidity workshops. However, electrostatic jumpers only target the main body of the equipment and cannot eliminate static electricity generated on the surface of the inorganic powders inside. Atomized humidification inside the equipment has drawbacks such as high water consumption, uneven humidification, and the introduction of condensate, significantly affecting product quality. Constructing constant temperature and humidity workshops is expensive, energy-intensive, and yields minimal results in improving the adsorption and agglomeration of inorganic powders caused by excessive localized static electricity inside the equipment.
