Airtight air charging device for desalting of relics obtained from water

Abstract

The invention provides an airtight air charging device for desalting of relics obtained from water. The airtight air charging device comprises an airtight water tank, a bubble generation device, a water source, an inert gas source and a detecting device; a water outlet of the airtight water tank and the water source are connected with a water inlet of the bubble generation device through stop valves correspondingly; an outlet of the bubble generation device is connected with an inlet of the airtight water tank; an air inlet of the bubble generation device is connected with the inert gas source; the airtight water tank is connected with the detecting device; a gas exhaust valve is arranged on the airtight water tank; and a blow-down valve and / or a liquid sampling valve are / is further arranged on the airtight water tank. The bubble generation device is applied to protection of the relics obtained from the water, thus damage of chemical desalting to the relics is successfully avoided, and the relic protection effect is achieved; submicron bubbles enter surface-layer micropores of the relics obtained from the water so that deep cleaning and desalting can be conducted; and the submicron bubbles explode in the process of rising in the water to form local negative pressure, cleaning water is pushed to flow around the relics obtained from the, and efficient desalting can be achieved.

Description

technical field [0001] The invention belongs to the field of desalination, and in particular relates to an airtight inflator for desalination of water-exposed cultural relics. Background technique [0002] In the prior art, after being soaked in seawater for a long time, the surface and interior of the cultural relics containing water-soluble salts can only be soaked in water for a long time because the desalination of the cultural relics cannot be realized; however, various inorganic components form weak electrolytes, and a small amount of them in the water The combined effects of dissolved oxygen and other factors make the effluent metal cultural relics extremely prone to electrochemical corrosion and chemical corrosion. At present, conventional desalination methods for water relics include adsorption desalination, chemical cleaning, and special cleaning methods include steam jet cleaning, particle jet cleaning, laser cleaning, etc. Very unsatisfactory. [0003] At prese...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims to propose an airtight inflatable device for the desalination of cultural relics out of water to solve the problem of rapid desalination and dust removal after the cultural relics are salvaged out of the water, which may cause the cultural relics out of the water to be caused by salt analysis, electrochemical or chemical corrosion, etc. irreparable damage
