2results about How to "Improve deacidification efficiency" patented technology

This application provides a method for deacidifying powder, comprising: moving the powder to be deacidified in the same direction as a first high-temperature gas flow in a conveying channel and directly contacting it for heat exchange, thereby preheating the powder to a target deacidification temperature within the conveying channel; the preheated powder then enters a deacidification space, into which a second high-temperature gas flow is introduced, causing the powder to undergo deacidification treatment under the action of the second high-temperature gas flow. This application completely separates the preheating process from the deacidification reaction process spatially, ensuring that the powder is preheated to the target deacidification temperature before entering the deacidification treatment space. This eliminates temperature fluctuations caused by the addition of cold material within the deacidification treatment space, significantly improving the stability of the deacidification temperature. This application also provides an apparatus for implementing the above-described powder deacidification method.
