Drying device and method for paper immersion deacidification

The invention discloses a drying device and method for paper immersion deacidification. The method comprises the following steps: vertically placing a paper document soaked in deacidification liquid into an accommodating bin of a support frame body to enable the spine of the paper document to be in contact with the bottom of the accommodating bin, wherein the paper document leans on the oblique side wall of the accommodating bin in an open manner; heating the paper document by virtue of the support frame body, and maintaining the temperature when reaching the boiling agent of a deacidificationliquid carrier agent; and when the pressure difference between a tank body and the inside of a condenser reaches a preset value, opening a valve on a connecting pipeline between the tank body and thecondenser to enable gas in the tank body to flow into the condenser, carrying out cooling and condensing, and recycling the gas. According to the method, the drying time of paper can be shortened, and the deacidification safe
