Controlled atmosphere cultural relic protecting device and controlled atmosphere cultural relic protecting process

Abstract

The invention discloses a controlled atmosphere cultural relic protecting device and a controlled atmosphere cultural relic protecting process. The device comprises an air compressor, a gas storage tank, a nitrogen making machine and a humidifying device which are connected in series, wherein the humidifying device is connected with a cultural relic cabinet; the cultural relic cabinet is connected with an exhaust electromagnetic valve and is internally provided with an LED (Light-Emitting Diode) lamp and a temperature and humidity sensor; a gas sampling port of the cultural relic cabinet is connected with a gas detection device; the gas detection device is connected with the nitrogen making machine; the input end and output end of a circuit control device with a touch screen are respectively connected with the electrical signal input ends of the temperature and humidity sensor, a pressure transmitter, the gas detection device and the device. The controlled atmosphere cultural relic protecting process comprises the following steps of inputting parameters; enabling an circuit control device to act; controlling the pressure of the gas storage tank; controlling the oxygen content. The controlled atmosphere cultural relic protecting device has the beneficial effects that by virtue of controlling the on and off of the air compressor, the nitrogen making machine and the humidifying device, the oxygen content and humidity in the cultural relic cabinet are always kept in a set range, the content of air contaminants in the cultural relic cabinet is effectively reduced and the purpose of prolonging the storage life of cultural relics is achieved.

Description

technical field [0001] The invention relates to a cultural relics protection device and its technology, in particular to an atmosphere-modulated cultural relics protection device and its technology. Background technique [0002] Cultural relics are a special kind of material material, and their preservation life largely depends on the preservation environment of cultural relics. The aging speed and damage degree of cultural relics are directly related to the environment such as temperature, humidity, light, air pollutants, harmful microorganisms and insects. [0003] Nitrogen protection technology is currently internationally recognized as the most ideal preservation technology for cultural relics. This technology uses nitrogen to replace the oxygen in the storage space of cultural relics and archives, so as to prevent chemical oxidation reactions between cultural relics, archives and oxygen, and prolong the preservation of cultural relics. , File preservation life.
