Document Type and Number:
WIPO Patent Application WO/2021/031774
Kind Code:
A1
Abstract:
A large book deacidification device, comprising a liquid storage tank (1), a deacidification treatment tank (2) and a first gas pipeline (91) and a first liquid pipeline (92) penetrating the two, the first liquid pipeline (92) being positioned below the first gas pipeline (91), and the first liquid pipeline (92) having mounted thereon a first conveying apparatus (3). The gas pipeline (91) penetrating and between the deacidification treatment tank (2) and the liquid storage tank (1) aids transfer of deacidification liquid between the liquid storage tank (1) and the deacidification treatment tank (2), and prevents safety hazards caused by gas pressure in one tank being too high or too low because deacidification liquid is only delivered by means of a pump.
