Abstract

The invention provides a continuous deacidification system based on dielectric barrier discharge. The continuous deacidification system comprises a deacidification solvent atomizing device, a radio-frequency discharge device, a driving device, a first insulation layer and a second insulation layer. The deacidification solvent atomizing device comprises a deacidification solvent tank, an atomizing generating mechanism and a spray head for applying deacidification solvent to a sample to be deacidified, wherein the deacidification solvent tank, the atomizing generating mechanism and the spray head are communicated in sequence. The radio-frequency discharge device comprises a discharge electrode, a grounding electrode and a matched circuit, wherein the grounding electrode is made of flexible materials and is wound into a conveyor belt for carrying the sample to be deacidified. The driving device is used for driving the discharge electrode and the spray head to change the position of the discharge electrode and the position of the spray head relative to the conveyor belt. The first insulation layer is affixed to the outer surface of the conveyor belt. The second insulation layer is arranged above the first insulation layer, a gap between the first insulation layer and the second insulation layer is a channel for the sample to be deacidified, and the discharge electrode is arranged above the channel. According to the deacidification system, sample deformation and color change are effectively avoided. The deacidification system is suitable for large-scale industrial application.

Description

technical field [0001] The invention relates to a deacidification system, in particular to a continuous deacidification system based on dielectric barrier discharge. Background technique [0002] my country is an ancient civilization with a long history and splendid culture. The invention of papermaking and printing records the development of human civilization. There are tens of thousands of precious modern books, calligraphy and paintings, newspapers, archives and other paper cultural relics preserved in various libraries, museums and archives institutions in our country. Historical and cultural value is the pillar of the spiritual civilization of the Chinese nation. [0003] However, with the passage of time, the acidification of paper documents has become more and more serious, and a large number of ancient rare books have become yellow, moldy, pulverized and fragmented. The protection of these cultural materials is facing severe challenges. A large number of modern pa...
