Desalting well for cultural relics

Abstract

The invention provides a desalting well for cultural relics. The desalting well comprises an internal unit and an external unit, wherein the internal unit comprises a shell and a salt solution migration channel positioned in the shell; the external unit comprises a crystallization tank which is connected with the salt solution migration channel; and the salt solution migration channel and the crystallization tank both are filled with materials with water absorption performance. According to the desalting well, the damage of soluble salt to the cultural relics, especially large-scale and non-movable stony ruins, soil ruins and murals can be reduced.

Description

technical field [0001] The invention belongs to the field of cultural heritage protection, and relates to on-site protection of cultural relics and equipment for reducing or even removing the soluble salt content of cultural relics, in particular to a desalination well for cultural relics. Background technique [0002] The splendid civilization of the Chinese nation for thousands of years has left us many cultural relics that attract the attention of the world, such as stone, earthen ruins, murals and other large, immovable and precious historical and cultural relics. They are the precious wealth of human beings and are non-renewable. Invaluable cultural heritage and historical resources. [0003] These large, "immovable precious historical relics" are in contact with the groundwater in the soil, and participate in the movement and evaporation of groundwater, which leads to the continuous migration of soluble salts in the groundwater to the interior and surface of the cultur...

AI Technical Summary

Problems solved by technology

These methods are fast in desalting, but they are easy to cause damage to cultural relics during the process of soaking and pulp wrapping. During the rapid dissolution of crystalline salt contained in cultural relics, it is easy to generate greater stress on the pores of cultural relics, especially the inner walls of pores with loose structures. released, leading to damage to cultural relics during the desalination process
