Embodiment 1

[0055] The low-oxygen and constant-humidity rigid storage cabinet device of the present invention is used for low-oxygen and constant-humidity storage of bronzes. The volume of the hypoxic and constant humidity storage cabinet is 3m 3 , the ventilation rate is 0.02d -1 . Use iron-based oxygen scavenger to remove oxygen and control the oxygen content below 2%. The iron-based oxygen scavenger has the advantages of non-toxic, harmless and low cost. Use silica gel desiccant to control the humidity in the storage space. The target relative humidity is 30% ± 5%. The ambient humidity during storage is 68%, the temperature is 25° C., and the storage time is 6 months.

[0056] Calculate the dosage of oxygen scavenger according to the following formula:

[0057] m 1 =A 1 ·A 2 ·V·(C 1 -C 2 ) / Q+V·N·D·21% / Q;

[0058] Among them, A 1 = 1.3, A 2 = 1 (the space occupied by the bronze ware is very small, so it is ignored), V = 3m 3 , C 1 = 21%, C 2 =2%, Q=0.12m 3 / kg, N=0.02d...

Embodiment 2

[0070] The low-oxygen and constant-humidity rigid storage cabinet of the present invention is used to carry out low-oxygen and constant-humidity insecticide on ancient books. The volume of the hypoxic and constant humidity rigid storage cabinet is 2m 3 , ventilation rate 0.02d -1 . Use an organic type oxygen scavenger to reduce oxygen and control the oxygen content at 0.1% to 1% or below 0.1%, and maintain it for 2 weeks. Use silica gel desiccant for humidity control, and the target relative humidity is 55%±3%. The environmental limit humidity is 80%, and the temperature is 20±5℃.

[0071] Calculate the dosage of oxygen scavenger according to the following formula:

[0072] m 1 =A 1 ·A 2 ·V·(C 1 -C 2 ) / Q+V·N·D·21% / Q;

[0073] Among them, A 1 = 1.3, A 2 =0.5 (ancient books occupy 50% of the volume of the storage cabinet), V=2m 3 , C 1 = 21%, C 2 =0.1%, Q=0.04m 3 / kg, N=0.02d -1 , D = 14 days. Calculated by the above formula, M 1 ≈9.73 kg.

Abstract

The present invention relates to a low-oxygen constant-humidity device, which comprises an airtight enclosure having a volume of less than 20 m<3>; a deoxidant; wherein the deoxidant is configured toadjust and maintain the oxygen content in the airtight enclosure; a humidity control agent and/or a drying agent, which can be configured to adjust and maintain the humidity in the airtight enclosure;and wherein the amount of humidity control agent and/or drying agent and deoxidant is based at least in part on the volume and sealability of the airtight enclosure. The invention further relates toa regulation and control method of the low-oxygen constant-humidity device. According to the low-oxygen constant-humidity storage device and a storage method, an active oxygen reduction and humidity control device is not included, and the oxygen concentration and humidity in the airtight space in the storage cabinet can be kept constant without any ventilation equipment.

Description

technical field [0001] The present invention relates to a high sealed environment atmosphere protection technology (Controlled Atmosphere technology of High Sealed environment, CAHS), in particular to a low oxygen constant humidity storage device and a storage method thereof. Background technique [0002] The storage of cultural relics, ancient books and other collections has high requirements on the oxygen content and humidity of the environment. At present, due to the lack of effective control of the storage environment, some collections have appeared moldy and aging to varying degrees. The unanimous view in the existing technology is that only the active low-oxygen and constant-humidity air conditioning technology can keep the gas in the storage space in a low-oxygen and constant-humidity state for a long time, effectively reduce the mold and oxidation of the collection, and realize the long-term storage of the collection . However, the relatively high cost of active hu...
